Moodle Community Hub

One of the tools that we have selected to use at school is moodle, this provides teachers an online environment to put work and resources up online and use some of the activity modules to get feedback from the students.

We are now investigating the use of a community hub, though I believe that this will require a change in teachers minds. This allows teachers to publish there courses online for other teachers to use. There is the development of a New Zealand moodle hub through watchdog. http://hub.moodleinschools.org.nz. This is still under development and will hopefully be running by the end of the April school holidays, just requires some more testing to make sure all systems are go.

But will schools use it, one thing I will be pushing for at the next moodle meeting in Christchurch, is getting schools online and sharing resources, be it a quiz or total course. I also see a great need for it within our associations as well, to be able to collaboratively work and build a course up that others can use and modify.

I have another idea as well, but will have to debate this tonight.

Indicators of progression for Technology Learning Objectives

INDICATORS OF PROGRESSION FOR TECHNOLOGY LEARNING OBJECTIVES

These have now been released for Level 6 and 7, next year Level 8 will be released.
http://techlink.org.nz/curriculum-support/indicators/Learning-Objectives/index.htm

The Indicators of Progression (Indicators) provide support for teachers to interpret the Learning Objectives (LOs) for each specialist knowledge and skill technology component. They:
provide an overview statement that explains the focus of the Learning Objectives and an overview statement about student progression from curriculum levels 6-8;
restate the Learning Objectives for each level;
provide guidance to teachers on what they could do to support student learning at curriculum levels 6-8
provide indicators of what students should know or be able to do at curriculum levels 6-8; and
indicate the achievement standard(s) that align to the Learning Objective at curriculum levels 6-8.

Followup - Is Government failing ICT Teachers

ICT curriculum better, but support needed

ICT secondary school teacher says more professional development required

For 15 years Tania Samal has been teaching ICT to secondary school students at Whakatane High School. In that time she has seen three different governments, the introduction of NCEA, and for the last two years she has been looking at ways to integrate the new Digital Technologies standards into her school’s ICT curriculum.

Comments made by Hawkes Bay ICT educator Michael Peterson criticising the government’s support and focus on ICT, were understandable, but do not fairly reflect the progress that has been made in the curriculum in the past two years, says Samal.

“I feel he was a bit harsh towards the ministry. Maybe a couple of years ago it would be completely justified, but now the ministry is starting to get its act together,” says Samal.

In the last year the ministry has rolled out its new Digital Technologies standards for Level 1 NCEA , which were developed in conjunction with Canterbury University. A similar set of standards have been published for Level 2 this year, and the Level 3 standards will be available next year.

The new standards give teachers the option to teach a greater number of strands under the ICT umbrella, and gives them the tools to assess them using achievement standards instead of just the unit standards that were offered previously.

The ministry is not without its faults, says Samal.

“However, the ministry have run a lot of workshops in our region, but they’re held in Hamilton which is a two hour drive away. This, along with the tightening of our school budget means we’ve essentially been told that no one will be sent for Professional Development (PD) from our school,” says Samal.

Samal is also critical of the lack of resources provided to ICT teachers after the roll out of the new standards.

“We don’t have the time to create these curriculums completely from scratch. Right now teachers are helping other teachers by showing what they are doing in their own classes, but we need more resources from the ministry itself.”

John Creighton, president of the New Zealand Association for Computing, Digital and Information Technology Teachers (NZCDITT) says that in ICT, where content knowledge changes so rapidly, there is never enough PD.

The organisation, which was formed in 2009, has 400 secondary school members and associate members from tertiary institutions.

“PD has to be targeted to the teachers so they can be targeted to the students,” Creighton says, citing a recent collaboration between Canterbury University and Google to run a conference/workshop for teachers in Christchurch and Wellington.

He says NZACDITT is trying to develop regionally based PD programmes, but struggles to secure funding and resources.

The Minister of Education, Hekia Parata, has refused to comment. Computerworld’s questions to the ministry have yet to get a response.

Future of Technology

Why is it when I new technology comes out, especially these things I want them,

The Google glasses project sounds like a winner to me, I like the fact that they integrate with your phone, which means I still have control on what goes out. 

Questions that I am thinking about are: will it be available in my prescription? Are all of a sudden glasses going to be cool? Is there going to be a opacity control so it will not affect driving, walking?

from nzherald.co.nz
If you think texting while walking is dangerous, just wait until everyone starts wearing Google's futuristic, Internet-connected glasses.
Directions to your destination appear literally before your eyes. You can talk to friends over video chat, take a photo or even buy a few things online as you walk around.
These glasses can do anything a smartphone or tablet computer does now -and then some.
Google gave a glimpse of "Project Glass" in a video and blog post this week. Still in an early prototype stage, the glasses open up endless possibilities - as well as challenges to safety, privacy and fashion sensibility.
The prototypes have a sleek wrap-around look and appear nothing like clunky 3-D glasses. But if Google isn't careful, they could be dismissed as a kind of Bluetooth earpiece of the future, a fashion faux-pas where bulky looks outweigh marginal utility.
In development for a couple of years, the project is the brainchild of Google X, the online search-leader's secret facility that spawned the self-driving car and could one day let people ride elevators into space.
If it takes off, it could bring reality another step closer to science fiction, where the line between human and machine blurs.
"My son is 4 years old and this is going to be his generation's reality," said Guy Bailey, who works as a social media supervisor for Kennesaw State University outside Atlanta. He expects it might even be followed by body implants, so that in 10 years or so you'll be able to get such a "heads-up" display inside your head.
At its best, the goal is to make your life easier by putting the tools now at your fingertips in front of your eyes.
"There is a lot of data about the world that would be great if more people had access to as they are walking down the street," said Jason Tester, research director at the nonprofit Institute For the Future in Palo Alto, California.
That said, "once that information is not only at our fingertips but literally in our field of view, it may become too much."
Always-on smartphones with their constant Twitter feeds, real-time weather updates and "Angry Birds" games are already leaving people with a sense of information overload. But at least you can put your smartphone away. Having all that in front of your eyes could become too much.
"Sometimes you want to stop and smell the roses," said Scott Steinberg, CEO of technology consulting company TechSavvy Global. "It doesn't mean you want to call up every single fact about them on the Internet."
Still, it doesn't take much to imagine the possibilities. What if you could instantly see the Facebook profile of the person sitting next to you on the bus? Read the ingredient list and calorie count of a sandwich by looking at it? Snap a photo with a blink? Look through your wall to find out where electrical leads are, so you know where to drill?
"Not paint your house, because the people who looked at your house could see whatever colour they wanted it in?" pondered veteran technology analyst Rob Enderle.
Wearing the glasses could turn the Internet into a tool in the same way that our memory is a tool now, mused science fiction writer and computer scientist Vernor Vinge. His 2006 book, "Rainbow's End," set in the not-so-distant future, has people interacting with the world through their contact lenses, as if they had a smart phone embedded in their eyes.
"Things we used to think were magic, we now take for granted: the ability to get a map instantly, to find information quickly and easily, to choose any video from millions on YouTube rather than just a few TV channels," Google CEO Larry Page wrote in a letter on the company's website Thursday.
In Google's video, a man wearing the spectacles is shown getting subway information, arranging to meet a friend for coffee and navigating the inside of a bookstore, all with the help of the glasses. It ends with playing the ukulele for a woman and showing her the sunset through a video chat.
Google posted the video and short blog post about Project Glass on Wednesday, asking people to offer feedback through its Google Plus social network.
By Thursday, about 500 people did, voicing a mix of amazement and concern about the new technology. What if people used it in cars and got distracted? What about the effect on your vision of having a screen so close to your eye?
Some asked for prototypes, but Google isn't giving those out just yet. The company didn't say when regular people can expect to get their hands on a piece of Project Glass, but going by how quickly Google tends to come out with new products, it may not be long. Enderle estimates it could be about six months to a year before broader tests are coming, and a year or more for the first version of the product.
With such an immersive device as this, that sort of speed could be dangerous, he cautions.
"It's coming. Whether Google is going to do it or someone else is going to do it, it's going to happen," Enderle said. "The question is whether we'll be ready, and given history we probably won't be. As a race we tend to be somewhat suicidal with regard to how we implement this stuff."

enabling public_html user accounts in ubuntu

Running a ubuntu server distro for the students, we have encounted a number of issues which we have had to work through. One of these is to enable public_html in the users directory


In order to enable the user-specific public_html directory open up a terminal and switch to the apache module config directory:


cd /etc/apache2/mods-enabled

If you list all the files inside this directory you’ll notice that all of them are actually symbolic links. To enable mod_userdir, which is the module you’re interested in, you’ll have to create two symlinks to the relevant files:

sudo ln -s ../mods-available/userdir.load
sudo ln -s ../mods-available/userdir.conf

All done! Now restart Apache via:

sudo apache2ctl restart

We can now access the web applications stored in our /home/username/public_html directory via http://localhost/~username/

userdirectoryPHP enabled
https://wiki.ubuntu.com/UserDirectoryPHP

Webadmin Panel
Wondering if I should incorportae a web panel for this server?

Hack to the Future

This came in today on one of my feeds,

What is Hack To The Future?

It is an un-conference that aims to provide young digital creators aged 11 - 18 with positive experiences of computing science and other closely related fields, ensuring that the digital creators of today engage with the digital creators of tomorrow.
We plan to offer a day that will inspire, engage and encourage young digital creators in computing/programming so that they may:
  • consider developing a related interest/hobby
  • discover resources to support their continued interest
  • take part in other associated initiatives
  • be encouraged to study further
  • explore future careers in this field
  • benefit from meeting existing practitioners
  • see beyond gender stereotypes in technology 
Is this something that we should be looking at in our regions

Is the government failing ICT Teachers?


Govt failing ICT teachers says tech educator

Head of ICT at Hukarere Girls' College says barriers in the curriculum makes it difficult to teach employable skills.
The Ministry of Education is failing ICT teachers, and by doing so the New Zealand technology industry, says one Hawkes Bay educator.

Michael Peterson is head of department for ICT and technologies at Hukarere Girls’ College near Napier. He says barriers in the ministry’s curriculum make it difficult to teach employable IT skills, and discourage students from taking it up as a career.

“They’re failing ICT teachers, the students, and they’re failing the industry,” says Peterson.

But associate professor of computer science and software engineering at the University of Canterbury Tim Bell, who advises the ministry on its IT programme, disagrees, although he does admit that the professional development required to teach new standards has been “haphazard.” This is because the roll out was affected by the earthquakes in Christchurch last year.

“There were a lot of professional development courses, but the roll out was bumpy. It was made worse when the quakes struck,” says Bell.

“Many of the members of the New Zealand Association of Science Educators (NZASE) who we partnered with for the courses were in Christchurch, and understandably they went off the radar for while after February.”

Bell says the ministry has not done enough to support teachers in adopting the new standards. He recommends it does more to cover the associated costs involved, such as travel and accommodation, which are currently not paid for by schools.

“The standards themselves are excellent, and if the ministry could help the teachers out it would be by getting more of them onboard with it and giving them the professional development they require.”


NZQA focuses on “static” IT skills

Peterson says the current ministry-provided ICT curriculum for senior students (Years 11, 12, and 13) focuses on outdated and “static” IT skills, instead of general “IT thinking” like programming theory, strategy, and logic; which would prepare students for higher education in ICT and careers in the sector.

Because of NZQA guidelines regarding how credits can be earned, Peterson says there is very little room to change the teaching plan for seniors.

But Bell says the introduction of new standards for ICT will help alleviate some of the pain felt by ICT teachers like Peterson.

The new standards introduce a range of topics to the ICT subject at a secondary level, including addressing some of the complaints made by Peterson. There is a new focus on the technical side of computing; including programming, computer science, electronics, digital media and infrastructure.

Bell says the first of these standards were published last year for Level 1 NCEA, and include achievement standards instead of the lesser unit standards. Level 2 has been rolled out this year, and Level 3 will be available in 2013.


Focus on Year 9 and 10

In the meantime, Peterson says ICT teachers like him are having to take matters into their own hands and are teaching those skills to secondary school juniors.

“They [the ministry] have little control over us in Years 9 and 10. It’s at Year 11 that we need to conform to NZQA standards,” says Peterson.

“Some of my colleagues in teaching ICT aren’t too sure about what they should be doing. Quite a few people like me have a damn good idea what we should be doing, and we’re doing it – regardless of what the ministry thinks.”

In Peterson’s class, he teaches his Year 9 students about robotics, general programming theory, and the Alice and Scratch graphical programming languages.

Five students from Hukarere Girls’ College came third in the 2008 Robocup Junior robotics competition with their haka-performing entry.

Peterson says what little ministry guidance ICT teachers are given for Years 9 and 10, is better suited “for children of two decades ago”.

“The year nines are coming into school much more advanced than they were a few years ago, so much so that a lot of my juniors are capable of doing year 12 work, which has become very static... The ministry underestimates these kids. We’re teaching them how to do Powerpoint documents, which is good but doesn’t really impress an employer when it’s put on a CV,” says Peterson.

“In my class of 25 students, I’m running eight to ten different programmes at different levels, and it changes depending on the student,” says Peterson.

“That would be very hard in any other subject, but IT is perfect for it. It lends itself to this kind of teaching and the children are generally thrilled about what we do.”

Peterson says what frustrates him the most is what he perceives as a lack of interest from the ministry in ICT as a subject.

“We secondary school teachers can be enthusiastic about IT, and show our students what’s possible in an IT career, but it’s hard when it seems the ministry doesn’t give a damn,” says Peterson.

Peterson agrees with recent comments made by Orion Health CEO Ian McCrae in Computerworld, that ICT should be taught as the fourth science. He says most senior students take ICT as an easy way to earn unit standards to pass other subjects. It is not until ICT is given the same weighting as the other sciences that we will see more students take IT as a career option, says Peterson.

When asked if he or his school could face repercussions for his comments, Peterson replied simply, “It’s something that’s got to be said.”

Computerworld has approached Education Minister, Hekia Parata, and the Ministry of Education for comment. The minister has declined to comment, referring our questions to the ministry. The ministry has failed to respond so far.

things are broken

Creating a strategic plan
The school I am at last year went through a Core Ed IT Review, this was to help the school plan for the next five years, while for some of us that turn up at the Professional development, are following twitter and Virtual learning Network are up with the play, there is a large amount of people that are just doing the bare minimum. Yes it is nice to have Ultra Fast Broadbast, the School Network Upgrade Project happening, it is how you use it, do we look at a BYOD programme, what do we need to run a BYOD programme in the school. A lot of people look at the infrastructure needed, but I think its more than that. I think its the community, staff and students needing to have a conversation about learning. I am sorry to say that teaching and learning has changed from when the parents of these students went to school, that the Grandparents on the Board of Trustees that come in and sit in the same seats in the same room that they were taught in the 1960’s that Teaching and Learning has changed, and we as a school need to keep up with the changes. Ok, Tradition does have an impact on our school, and I am not wanting to remove that, however, the traditions that we have can be built on and improved. We talk about excellence and high standards with our students, then why does the introduction of technology in ones teaching and learning seem to make people think that the grades will not come out of it. I love listening to Derek Wenmoth talk about the work that he has been doing. If a teacher is only looking at technology as the answer to everything they are looking at it wrong, they need to include the pedagogically driven decisions to make it work.

Three days later.
The strategic plan has just been thrown out the window and all roads lead to a fun and exciting time, even though some people at school don’t think so and are upset at the decisions that have been made. We have been under a bit of stress at present around school as the closure of classrooms due to buildings not meeting code. Getting the school started was the priority of the board and marquees and changes to other spaces to replace 6 classrooms were needed. However these were a short term measure, the time has come for changes to happen, as the days get colder and the wind picks up these marquees are becoming unsuitable for human cohabitation. So the senior leadership made the decision to look at how we are using the spaces in the school. The original idea was to remove all the computers out of the library computer space, though this leads to some interesting things happening, we lose one of the most valuable spaces in the school. I believe that libraries are almost like our chapel at school. they are a place of learning and research, and should be a place where students come together to gather information, analyze it and communicate there findings. It is an English teachers second home. The space currently has 28 computers in it and has been upgraded in its cabling. The space right beside it will be for the Video Conferencing equipment. The space also has glass around three walls, this would seem like you are teaching in a goldfish bowl.

We have another space at school, The 3rd Computer Suite, this is a space that is a converted classroom only 3 years ago. This classroom was designed and built by one of the current staff at the school. The computers in it are a good quality and the room is heavily booked. However, the core ed document and current discussions are that computer labs will be a thing of the past in a few years time. As BYOD comes in and netbook classes are developed these rooms will no longer exist. The suggestion was to look at netbooks now, this is 12 months ahead of where we were looking at. The installation of wireless also needs to happen to take advantage of the opportunity as well. This is huge financial hit for the college, however it is also a saving as well. With the cost of the marquees taking a good hit of the college funds and no idea if the costs will be meet by insurance companies as the buildings have been taken out as they don’t meet code, not earthquake damage, although there is damage been done, it may not mean that the building is unsafe. It is a catch 22 situation. With the marquees gone and the changes of space until other decisions have been made we get to advance on the path towards BYOD. The netbooks will be setup the same as our computer labs, same software and access to resources, though they will need there SSID as they will require access to the entire network. The same setup as the teachers will require. It also means that we can get teachers trying out different things, they can experience and develop their teaching to make use of the BYOD devices when they come into school. They can try out layouts in the class, work through blended learning. This all requires some form of PD, though we are currently writing a document for some assistance towards this as the ICT group see this as of greatest need. We are reviewing our core ed document and items that we were developing for terms 3 and 4 and now going to have to be pushed up to terms one and two.

Beginning of the year itis

I think it could be that it is the beginning of the year and all the wonderful holiday stuff is now a distant memory. But do I really want to continue. It is coming up to 10 years of teaching next year, and all I can think of was the wonderful refreshment leave I took just over three years ago.
No matter what school people seem to be in, there are issues around technology, class sizes and peoples perceptions of the curriculum and what needs to be covered.
I think one of the biggest issues for me currently is the school is still struggling to develop where it is and where it wants to go. It seems to be following what others are doing are not developing its own ideas and developments. Last year the development started with the introduction of a new digital teacher, this started the development of the schools learning management system and google apps. However, this has been great, there has not been the adaption of the system, why... the students can only access it from home or in a school computer lab, 4 labs of 30 machines. Not enough. Why would one of the four curriculum areas provide information on the system when they are unable to access it in class. I see this as being a great way to assist students with the divergence in there ability, there is another word, but I can not think of it at the moment.

Can we afford to be another year behind?

There is also the issue of class size, 28 year 13 students in one class...

The school needs to think about the future and where they want students be, a graduate profile would be of great assistance, where do we see our students, what values, what ideas, are the New Zealand Curriculum Key Competencies enough?

stories from todays news

iPads highlight need for tech-savvy teachers
School is back for most students this week and many will return to class rooms kitted out with the latest gadgets like iPads.
There are concerns teachers might not be able to keep up with their increasingly tech-savvy students, with the Government rolling out ultra-fast broadband to schools across the country.
Knowing how to work the latest technology is becoming increasingly important as many schools are putting iPads on stationery lists.
Education consultant Dr John Langley says those able to use technology has come along in leaps and bounds over the past two decades.
“When I look at the ability that children and adults have to access information today, it's just vastly superior to anything that occurred 10, 20 years ago,” he says.
But Dr Langley is concerned that some teachers may not have moved as fast as the technology has.
“For the older teachers it's much more of a struggle,” he says. “I think in that case, what we do require for them is quite significant ongoing professional development.”
The Government says the biggest issue for schools is getting connected in the first place. It is aiming to give most of them access to ultra-fast broadband within three years and is confident teachers will be ready.
Prime Minister John Key says it is up to the principal of the school to ensure teachers feel comfortable with what they are using.
“Those who are technologically friendly are assisting their other teachers, and there are always training courses that we can and do send teachers on.”
The Post Primary Teachers' Association (PPTA) says professional development in information technology is woefully inadequate. It wants the Government to provide more so that teachers are not being left to struggle on their own.

Trying to work out what the difference is...

This came through a post last week, where the author mentioned three different types of teacher.
e-teachers, m-teachers and c-teachers, so what is the difference...

e-teacher
E-teachers are the new generation of teachers who will work in an Internet environment in both regular and virtual classroom situations. They will build new concepts of working in time and space. E-teachers collaborate, build and discover new learning communities and explore resources as they interact with information, materials and ideas with their students and colleagues.

m-teacher
M-teaching- Teaching with the support of mobile, handheld devices.

c-teacher
Doesn't use any devices in there learning at all?

Shut down or Restart

The Royal Society in Great Britain has just released a ground-breaking new report called Shut Down or Restart: The Way Forward for Computing in UK Schools which clearly demonstrates that the current challenges we face in K-12 computer science education are indeed global challenges..
The work behind this impressive report was carried out by the Computing at School project which did a comprehensive review of computing in UK schools. According to the Royal Society, the key points of the report are as follows:
1. The current delivery of Computing education in many UK schools is highly unsatisfactory. Although existing curricula for Information and Communication Technology (ICT) are broad and allow scope for teachers to inspire pupils and help them develop interests in Computing, many pupils are not inspired by what they are taught and gain nothing beyond basic digital literacy skills such as how to use a word-processor or a database. This is mainly because:
a. the current national curriculum in ICT can be very broadly interpreted and may be reduced to the lowest level where non specialist teachers have to deliver it
b. there is a shortage of teachers who are able to teach beyond basic digital literacy
c. there is a lack of continuing professional development for teachers of Computing
d. features of school infrastructure inhibit effective teaching of Computing
2. There is a need to improve understanding in schools of the nature and scope of Computing. In particular there needs to be recognition that Computer Science is a rigorous academic discipline of great importance to the future careers of many pupils. The status of Computing in schools needs to be recognised and raised by government and senior management in schools.
3. Every child should have the opportunity to learn Computing at school, including exposure to Computer Science as a rigorous academic discipline.

4. There is a need for qualifications in aspects of Computing that are accessible at school level but are not currently taught. There is also a need for existing inappropriate assessment methods to be updated.
5. There is a need for augmentation and coordination of current Enhancement and Enrichment activities to support the study of Computing.
6. Uptake of Computing A-level is hindered by lack of demand from higher education institutions.

computer science and obama

I found this youtube video the other day, this looks like it could be a good one to use with the students, to get them to give an explanation why Obama is right, as well as giving an explanation on what other methods could be used.

Also I came across this site http://apcentral.collegeboard.com/apc/public/courses/teachers_corner/4483.html

In this there are some team problems to be solved using computer science,

They are meant to be done by pairs of students during a class period. I tell my students to try to finish by the end of the period; if they can't, they may complete the assignment for homework and turn it in at the beginning of the next class. Each pair of students (or trio, if you have an odd number of students) turns in one solution, although it may contain one or more pages written by each team member. Each problem is worth 15 points and each student on the team gets the same score unless there is evidence that one student did all or most of the work. An overarching goal of all the problems is to give students experience in working with at least one other person to solve a substantial problem (that is, "substantial" for them at that point in the course). The "larger" nature of the problems lends itself to team solution. In some cases, the problem sheet suggests a way that the two students can divide the work.

Here is a list of the problems.
  1. Averaging Numbers: Write an algorithm for averaging a list of numbers. Focus first on the problem of knowing when the user is finished entering the numbers.

    Objective: To make students think about this standard algorithm before they develop a program for it in subsequent classes or labs

    Prerequisite knowledge: How to input and output numbers; For and While loops

  2. Putting Numbers in Ascending Order: Draw a flowchart for the problem of arranging three numbers in ascending order. Then trace the flowchart using a given set of test data.

    Objective: To have students develop the if-then-else logic required to solve this standard problem before they write the code for it in subsequent classes or labs

    Prerequisite knowledge: How to draw a flowchart with input/output and decision symbols

  3. String Searches: Apply a "brute-force" method to determine if a given string is contained in another string. Then apply the Boyer-Moore algorithm to the same task and note the reduction in the number of steps.

    Objective: To have students apply a search algorithm that is not part of their regular classwork

    Prerequisite knowledge: How to use a pointer to move through a string; comparing characters

  4. Swapless, Pushless Sorting: Develop an algorithm to sort a list of integers into descending order without swapping any values or pushing values up or down.

    Objective: To have students create a sort algorithm that is more efficient than the ones they have learned to code (e.g., Shuttle-Interchange, Bubble)

    Prerequisite knowledge: At least one sorting algorithm, so as to understand the idea of comparing numbers in a list and swapping those that are out of order

  5. Dealing Cards: Develop several algorithms for dealing a deck of cards and storing them in the computer's memory.

    Objective: To have students develop multiple approaches to a problem that underlies numerous card games, including poker and solitaire

    Prerequisite knowledge: How to store data in one- and two-dimensional arrays; random number generation; if-then logic

  6. File Compression: Apply the LZ algorithm to recreate a file from its condensed version and to condense a given file as much as possible.

    Objective: To apply a compression/decompression algorithm to "unzip" and "zip" files

    Prerequisite knowledge: Understanding of the concept of file compression and the LZ algorithm

  7. Seven Segment Display: Apply the techniques of Boolean algebra to design circuitry to run a seven-segment display for one digit (as used for calculators, cell phones, etc.).

    Objective: To apply Boolean algebra techniques to a "real-world" problem that students are familiar with

cypher

Looking at getting students caught with level 2 computer science, one of the things that we have to look at is cyphers, looking at what movies have cyphers in then. One is Allendorf Cipher

I hope this video will still exist when I goto teach this unit www.youtube.com/watch?v=KqI3SwDYbj8

Yet another is the playfor? Cypher

The elephant in the room

This is going to be a post that will evolve over time, I came across this blog post this evening which has got me thinking about the difficulties of teachers evolving in schools with technology. http://blog.core-ed.org/derek/2011/11/elephant-in-the-roo.html - by Derek

Consider the following notes so I can get my thoughts in order, they are direct quotes from the link above.
  • The avoiders – "I'll make time for the ICT PD once I've done everything I need to for NCEA implementation…
  • The excuse makers – "My laptop has never functioned properly, so I can't really do that.."
  • The apologists – "I just don't seem to be able to make it work, it must be my glasses or something…"
  • The debaters – "We really need to be sure we're using the technology for the right reasons, not simply because it's there…"
  • The pessimists – "Technology is leading us down a road to destruction, there are so many problems lurking online…"
Consider now the case in a school, where, after consultation with the staff and parents, the decision is made to establish an online environment where resources and learning support can be made available for students to access in their own time. The school and its community agree that this is a positive thing to do in supporting students to become self-managing learners, and provides parents with the ability to take a more active interest in the work their offspring are engaged in. The action is included in the school's strategic plan and signed off by the BOT, with the expectation that every staff member will make a contribution to the online resource pool in order to make the online offerings complete. How do we then regard the teacher who, at the end of the  year, hasn't made any move to contributing, and defends his/her position with excuses/apology/debate etc.? No student has died. No student has been put at risk (apparently). But the fact remains that an expectation, agreed by the BOT and school management hasn't been met.


This is the elephant in the room. We don't want to offend sensitivities. We make excuses for the teacher(s) involved – they are overworked, they are too old (or too young), they have had a rough year, etc. Other staff attempt to 'fill the gap'. Resentments loom large and rifts begin to occur among staff. Expectations are revised, and in the subsequent year's strategic plan putting materials online for students becomes an 'option' for staff. The refusers win, and the learners lose.
Having heard of and witnessed such concerns for some time now, I have come to the following conclusions:
  1. It's time for leaders to lead. They must be prepared to take responsibility for following through on the strategic goals set by the school. These are not to be treated as a 'wish list', but as a plan containing specific actions and expectations backed up by evindence-based decision making.
  2. Every teacher should be be provided with opportunities for professional development that is relevant to their needs, and assists them in fulfilling the requirements of the job they do. Without it, such requirements become un-enforceable.
  3. Schools need to have a robust process for involving all staff and their communities in developing a vision and strategic plan, particularly where new initiatives are contemplated. Such decisions need to be reached on the basis of informed, future-focused thinking that is focused primarily on preparing students for their future.
  4. Teachers in schools need to be held to account for the contribution they are expected to make to the agreed strategic direction of the school. there ought to be clear links between the intentions of the school's strategic plan, and the objectives included in a teacher's performance review at the beginning of each cycle.
Such instances in schools may be rare – but where they do occur, it is the impact on students that I am concerned about – and of schools who remain continually unable to achieve the goals they set for themselves in terms of meeting their students needs. How much longer can this be tolerated?

Southland accent

The good Lord blessed me with a thick Southland accent, including the famous Southland 'R' - misrepresented by Jim Mora in this mercifully brief documentary, which makes the spurious claim that the Southland 'R' pulls chicks.

Another feature of Southland speech is our single, multi-purpose vowel, which is best pronounced with a closed mouth and also sounds like 'R'.   Combine these two potent features of Southland dialect - the R and the R vowel - and you're living in a powder keg and giving off sparrrrrrrrrrrks.

Pencilchat outcomes

  1. No, we don't have an Acceptable Use policy for pencils. I refuse to do this, because I don't have a policy for slates, for compasses (for more dangerous, in my opinion) or for chalk. If you want it to be an issue of compliance, I'll comply - but only through paperwork. I don't believe in it.
  2. Pencil predators are real, but most abuse happens in-person via close social relationships. I suggest an open dialogue with parents about monitoring pen pal letters. 
  3. Pencils aren't making kids narcissistic. They're in junior high which means they are naturally self-centered. The good news is that pencils provide a platform for self-awareness.
  4. I see your concern about Pencil Citizenship and it's being addressed, but I'd like to push back a little and suggest that ethics and social justice might be a better approach. And not just with pencils, but with life. 
  5. Banning pocket paper devices (i.e. tablets) is a really bad idea. Yes, they pass notes, but they're also learning to use these tools well. Let's allow students to learn how to use these tools for learning.
  6. Please quit banning Bullying is a real issue, but the most common method is still verbal and the most common site is still the cafeteria. Are we going to ban food next?
  7. Students aren't addicted to paper. Really, they're not. They're addicted to social interaction in the same way they are addicted to water and to oxygen. 
  8. I see your concern with violent games, but I played Hang Man and I'm not violent. It's really not as big a deal as you think.
  9. Teachers are motivated to use pencils. The real issue is self-efficacy. Many of them want to use the tools, but they're scared. Slate-based testing is a major component to this. There is a fear that learning can't transfer from one medium to the next. 
  10. The real issue is pedagogy. The power in the pencil is the nuance, the paradox, the gray area. It's in the idea of portability and permanence. It's about empowering each student to learn in a personalized way. It's a chance to erase and thereby move away from summative and toward formative assessment.

Ar drone and Getting student to learn to operate and challenge
Use vc unit to have real challenges with other students
Take mk you think to cs4hs and get teachers stumped over rules, when the rules havent been defined.
Challenge between schools, vs and over a number of days/afternoons throughout the year challenge students to think outside the square and be able to explain why/how technology has influcended there decisions
CCES competition to look at thinking skills rather than person that can do it.

Cup stacking competition - this is actually a sport and available in New Zealand - http://www.speedstacks.co.nz
What is sport stacking?
Sport Stacking with Speed Stacks is an exciting individual and team sport where participants of all ages and abilities stack and unstack 12 specially designed cups (Speed Stacks) in specific patterns with amazing precision and dexterity. Competitors stack on a StackMat®, either individually against the StackMat clock or head-to-head in relay teams.
Active and healthy, sport stacking improves ambidexterity, concentration and hand-eye coordination. A university study has shown that sport stacking increases bilateral proficiency; equal performance on both sides of the body, which helps develop awareness, focus, creativity and rhythm.

This is more about think and problem solving than doing
Byod debate, as part of the christchurch debating programme and record these for byod vln to show student voice
Newspapers from the press, contact them for numbers to help with no tech challenge. To take back bp tech challenge from science and win because we are technology. 10 challenges with points up for grabs between the schools, needs a trophy to make the point with principals.
Needs to be formalized and come with with a structure to show for students to come up with an answer. Want to move away from spegittei and marshmallows.
Shared course that we can develop.
Friday challenge days. Me to see if he can find the blog on the companies Friday afternoon challenge, ie graphic design,logo,game character, web site creation based upon existing work and imitating.
Main development is around thinking, key competencies!!!!

perfect computer lab

Having traditional computer labs and not allowing kids to bring their own devices is not preparing them for college or life.

missing Get Lost!

I am missing Get Lost! this year, a project that captured my imagination and use of Technology to solve puzzles, challenge students and all in all have a good time. However, with moving schools comes different challenges.

The school I am at has two activity days. I decided that I wanted to do something different as what I have done in the past is not available to me currently. There is no CBD, there are a massive amount of fences that surround it. There are other opportunities, but the two day period is prohibitive on creating something exciting.

So Get Cranked was born. Two days of Mountain Biking with a group of four students using the car as a way of getting from venue to venue, some hundreds of kilometres apart.

Day two's venue had to be changed due to information received last week.
An Alert was posted on the DOC website as well as the vorb.org.nz that Poulter River track was closed
Poulter Valley Track is closed
The track is closed between the Poulter Bridge (Mt White Rd) and Pete Stream due to recent flooding completely destroying the track in numerous sections. The washed-out sections cannot be safely crossed.

So a trip to Hamner Springs is on the cards instead, going and having some fun on the Mountain Bike Tracks, yes it does have some Key Competency links with the New Zealand Curriculum, but not the same as Get Lost!

In the last couple of weeks since working out what I was going to do I have thought about some other projects, more related to Community.
There is a community garden that is at the old Edmonds Factory site which had a large amount of liquefaction destroy its ponds and gardens, grabbing a car load of students and a trailer would have been a wonderful project to help assist one of the cities assets to come back to life.

Another was the idea of an outdoor classroom, in the middle of RE:start, for students to go around and document the development of the CBD as well as some of the emptiness around the town. Though we are not quite there yet with our technology it would have been possible to find some laptops and cameras and give it a go to develop a site to show those outside of the city what we have. Maybe this could be a field trip next year?
