#NZCTech Day 10 Looking at Tech systems from a senior level

Excerpt from the systems explanatory paper

Operational parameters of systems refer to the boundaries and/or conditions within which the system has been designed to function. These concepts are important to understand when establishing the fitness for purpose of technological systems. Ethics play a significant part in the decisions around reliability and redundancy, as improvements in both these areas within a system inevitably comes with associated costs.

Technological systems in the junior technology programme
If you are attempting 91050, 91360, and/or 91614 
it is critically important to cover the Technological systems component at curriculum levels 3, 4, 5

Technological systems in the junior technology programme
Comments from the NCEA assessment reports:
  • had a limited understanding of what a system is
  • described non-technological systems such as managerial or organisational systems.
  • misunderstood what a subsystem is referring to components as subsystems e.g. LEDs

Technological systems
What is a technological system in terms of input / transformation / output and how technological systems differ from other systems.

Technological systems at curriculum level one
Students can:
  • identify the components of a technological system and how they are connected
  • identify the input/s and output/s of particular technological systems
  • Identify that a system transforms an input to an output.

Technological systems at curriculum level three

Students can:
  • describe what ‘black box’ refers to within a technological system and the role of particular black boxes within technological systems
  • identify possible advantages and disadvantages of having black boxed transformations within particular technological systems
  • describe how the components, and how they are connected, allow particular systems to be technical feasible and socially acceptable
  • describe particular technological systems using specialised language and symbol conventions.

Contexts to study systems

Technological systems
Don’t have to be ‘hi-tech’ systems

Programme planning
So…how is understanding of the Technological Systems component developed in your junior technology programme?

How is understanding of the Technological Systems component developed throughout your senior courses?

An issue is that the resource is no longer available.
