Engaging students in designing, testing, and revising engineering models using mathematical representation of data from scientific investigations helps them embody the science and engineering practices highlighted in the "Next Generation Science Standards" (NGSS Lead States, 2013). The practices of modeling, conducting failure analysis,…

As environmental changes become a significant societal issue, elementary science curricula need to develop students' understanding about the key concepts of energy and climate change. For teachers, developing quality learning experiences involves establishing what their students' prior understanding about energy and climate change are. A survey…

To reduce curricular fragmentation in science education, reform recommendations include using common, unifying themes such as scaling to enhance curricular coherence. This study involved 215 participants from five groups (grades 5, 7, 9, and 12, and doctoral students), who completed written assessments and card sort tasks related to their…
