Thank you for the insightful review on pedagogical approaches in fostering innovation among K-12 STEM learners. While the paper presents a broad and systematic synthesis, I would like to raise a few points for clarification:
1. Could you elaborate on how they defined and measured “innovation” across the included studies, given its varied interpretation in educational contexts?
2. What criteria were used to assess the quality or rigor of the selected studies beyond meeting the inclusion/exclusion requirements?
3. The review highlights various pedagogical strategies, but how were their comparative impacts on student innovation evaluated or ranked?
4. Given the diversity of countries represented, how did the authors account for cultural or systemic differences that may influence the implementation and effectiveness of these pedagogies?
These clarifications would strengthen the applicability and theoretical grounding of this valuable work.
