SUGGESTED ANSWERING TECHNIQUES. 1.

INSTRUCTIONS 1.1

Teachers should explain the suggested techniques on how to answer questions to the pupils.

1.2

Ensure that pupils can identify the Master Keys which are the manipulated variables or what to change (MV / wtc) and the responding variables or what to observe (RV / wto). Clarify about the fixed variables or what to keep the same (RV) too.

1.3

Pupils should be exposed to the method of identifying parameters and patterns of (MV / wtc) and (RV / wto)

1.4

Enable pupils to write (MV / wtc) and (RV / wto) in the master key diagram found in the questions.

1.5

Teachers can use the time frame suggested in the module table.

1.6

Discuss the answers and correct the mistakes. The result can be filled in the assessment form.
