Which of the following operations comes under the pre-active phase of teaching according to Philip W. Jackson?

Deciding about teaching strategies is a pre-active operation, the planning done before entering the classroom.

Diagnosis of the learners occurs in the interactive phase while teaching is underway.

Actions and reactions between teacher and taught belong to the interactive phase.

Selecting appropriate testing devices is a post-active operation of evaluation.

The pre-active phase fixes objectives, content, sequence and methods in advance.

Philip W. Jackson described these three phases of teaching in his work Life in Classrooms (1968).
