Demonstrate logical problem solving and error detection techniques

Season:1

Describe different approaches to problem solving.

The description identifies the different problem solving techniques.

The description identifies situations where specific problem solving techniques would be more suitable than others

The description utilises the top-down problem solving approach in real life problems known to the learner.

The description allows for the practice of problem breakdown in picture drawing applications.

Season:2

 

Usage describes the logical operators by drawing truth tables

Usage provides examples of problem situations where a specific operator can be used

Usage identifies which of the operators should be used to represent given situations.

Usage combines different operators to form Boolean expressions by setting up truth tables.

 

 

 

 

Season:3

 

Simplify Boolean expressions with Boolean algebra and Karnaugh maps.

The simplification describes the rules of Boolean algebra.

The simplification uses the Boolean algebra rules to simplify given expressions.

The simplification uses Karnaugh maps to represent Boolean expressions.

The simplification involves writing down the simplified expression from the map.
