Which of the following is NOT an effective strategy for teaching-learning?

Effective teaching-learning strategies are those that actively engage learners in constructing knowledge — through their own reasoning, actions, interactions, and inquiry — rather than having them passively receive and repeat information exactly as given. Constructivist and experiential views of pedagogy hold that learners build understanding rather than simply absorb it, so a genuinely effective strategy must activate the learner's own thinking, action, or social exchange.

Judged against this principle, a strategy that lets learners guess, experiment, or discuss activates their own reasoning and engagement. A strategy that only asks learners to reproduce information exactly as presented, however, keeps them in a passive, receptive role and does not require them to think, act, or interact with the material.

• Encouraging intuitive guesses activates learners' own reasoning and hypothesis-forming, so it is an effective strategy.

• Experimentation and exploration let learners construct understanding through direct, hands-on engagement, so it is an effective strategy.

• Dialogue and discussion engage learners in articulating and refining ideas with others, so it is an effective strategy.

• Focusing on reproduction of knowledge as given keeps learners in a passive, receptive role with no reasoning, action, or interaction required, so it is not an effective strategy.

Reproducing knowledge exactly as given, without requiring learners to reason about it, question it, or build their own understanding of it, is therefore the strategy that is NOT an effective approach to teaching-learning.
