Peffer, Melanie E.; Renken, Maggie; Enderle, Patrick; Cohen, Jonathan – Research in Science Education, 2021
Young children can struggle to learn difficult disciplinary content and important skills for practicing science. Problem-based learning (PBL) may be useful for addressing such difficulties, yet evidence to support its usefulness in elementary school-aged children is limited. We considered the role of a PBL unit in improving students' genetics…
