An understanding of how sensemaking unfolds when elementary students engage in engineering design tasks is crucial to advancing engineering teaching and learning at K-12 levels. Sensemaking has been widely studied in the context of science as a discipline. In this paper, we seek to contribute to the more nascent efforts to build theory about the…

Science education researchers have highlighted how uncertainty can foster meaningful scientific sense-making, supporting students to re-evaluate their understandings of scientific phenomena and pursue deeper causal accounts. However, facilitating whole-class conversations motivated by uncertainty is complex and challenging, calling for further…

Compared "extended discretion" (ED) learning approach to traditional Biological Sciences Curriculum Study (BSCS) laboratory investigations. Found that although ED students are more capable of exercising independent judgment for greater lengths of time while BSCS demanded more teacher time, all teachers were still reluctant to accord…
