In the context of a dynamic teaching environment, which of the following statements is true?

In a dynamic teaching environment the teacher is an independent variable and the student is a dependent variable.

The teacher is independent because the teacher's action is the cause that is deliberately varied.

The student is dependent because the learning outcome is the effect that responds to the teacher's action.

Option A reverses the roles, wrongly making the teacher dependent and the student independent.

Option C wrongly labels both as intervening variables, which are inferred inner links, not the main cause and effect.

Flanders' interaction analysis similarly studies how teacher talk shapes and influences student behaviour.
