(1B) Methods of representing and measuring data electronically

2. Structure – How does it work?
Lab activates are not the same as you typical lessons. You should think of them a mini Challenges that you must complete in order. There are three types of challenge
Theory – This will be based on your classwork or reading
Practical – For this you must interact with the equipment and solve a simple problem
Identify – For this you must find a piece of hardware of information contained within the operating system

3. How do I know if I am doing well? (making progress)
Every task contains a checklist. You must first tick the red box to indicate you have started.
When you have finished the task you must draw an arrow to indicate if you managed to either
+ Red – Have completed the task but could not repeat the task without support
+ Amber – completed the task with a high level of support (but can now demonstrate the skill with ease)
+ Green – Have completed the task with low level support / / /

4. High Vs Low level support
We are expecting you to independently support yourself to complete each of the tasks.
The purpose of this is to develop your problem solving and researching skills.
Low level support is defined as:
+ Experimenting
+ Peer support
+ Websites (including youtube)
+ Book
High level support is defined as:
+ Using this presentation to support your tasks
+ Direct teacher intervention (teacher has to directly demonstrate beyond class teaching or has to do part of the task for you)
