Biology · Pedagogy of Science
In a lesson on light-dependent reactions of photosynthesis, the teacher presents data from an experiment where algae are exposed to varying light intensities and wavelengths. Students must calculate oxygen evolution rates, identify anomalous results, and propose mechanistic explanations linking pigment absorption to photophosphorylation. The teacher encourages reflection, justification of hypotheses, and comparison with peer reasoning. Which pedagogical approach MOST effectively promotes reasoning, metacognition, and conceptual understanding in this activity?
- 1Memorization of reaction steps and pigment functions, followed by simple data reading
- 2Teacher demonstration of oxygen evolution with calculation examples, but students do not generate hypotheses
- 3Guided inquiry with quantitative analysis, peer discussion, and reflective justification of hypotheses✓
- 4Inquiry-based data collection with peer discussion, but no structured reflection or hypothesis evaluation
Correct answer
Guided inquiry with quantitative analysis, peer discussion, and reflective justification of hypotheses
