Which of the following activities is considered part of the post-active phase…

Concept: The teaching process is commonly divided into three phases — the pre-active phase (planning, before teaching begins: selecting objectives, choosing and sequencing content, and deciding/allocating teaching strategies), the interactive phase (the live teaching-learning exchange: presenting content, diagnosing learners' needs, questioning, reinforcement), and the post-active phase (evaluation, after teaching ends: judging whether objectives were achieved and revising the approach based on the evidence collected).

Application: The question asks which activity is classified under the post-active phase. In this three-phase model, evaluating how the teaching went and revising the approach for the future is the defining task of the post-active phase. "Changing the strategies in terms of evidences gathered" is exactly this look-back, evidence-based revision, which is why it is classified as post-active rather than as a planning or in-lesson activity.

Cross-check — classifying the other activities:

• Deciding which teaching strategies to use and allocating them is a planning task carried out before teaching begins, which places it in the pre-active phase.

• Diagnosing learners' needs while presenting and questioning them during the lesson is part of the live teaching exchange, which places it in the interactive phase.

• Deciding the order in which content elements will be presented is a planning task finalised before the lesson is delivered, which places it in the pre-active phase.

So among the four offered activities, only "changing the strategies in terms of evidences gathered" is classified under the post-active phase, since it is the look-back evaluative revision that follows teaching rather than a planning or in-lesson action.
