J276 Computing 2.2 Programming techniques

This is a very comprehensive revision lesson (for Year 11 GCSE students) covering 2.2 in the OCR Computing spec.

• the use of variables, constants, operators, inputs, outputs and assignments
• the use of the three basic programming constructs used to control the flow of a program:
  * sequence
  * selection
  * iteration (count and condition controlled loops)
• the use of data types:
  • integer
  • real
  • Boolean
  • character and string
  • casting
• the common arithmetic operators
• the common Boolean operators.

The concepts are illustrated with Python examples and there are questions built into the PowerPoint.

The worksheet asks students to show their understanding of the concepts covered in the lesson, by identifying them within a Python program.

There is also a link to a Quizizz online multichoice test. (This is actually a resource that anyone can access but was written to support this lesson)
