Lapierre, Keith R.; Flynn, Alison B. – Journal of Research in Science Teaching, 2020
In this study, we investigated how students organized their knowledge about organic chemistry reactions in a transformed curriculum, including their choices, abilities, and changes over time. This transformed curriculum focuses on interpreting the underlying mechanistic patterns of chemical reactions and emphasizes the principles of reactivity in…

Göhner, Maximilian Felix; Bielik, Tom; Krell, Moritz – Journal of Research in Science Teaching, 2022
Worldwide, teachers are expected to engage their students in authentic practices, like scientific modeling. Research suggests that teachers experience challenges when integrating modeling in their classroom instruction, with one explanation that teachers themselves lack the necessary modeling competence. Currently, theoretical conceptualizations…

Shemwell, Jonathan T.; Chase, Catherine C.; Schwartz, Daniel L. – Journal of Research in Science Teaching, 2015
Evaluating the relation between evidence and theory should be a central activity for science learners. Evaluation comprises both hypothetico-deductive analysis, where theory precedes evidence, and inductive synthesis, where theory emerges from evidence. There is mounting evidence that induction is an especially good way to help learners grasp the…

Feldon, David F.; Timmerman, Briana Crotwell; Stowe, Kirk A.; Showman, Richard – Journal of Research in Science Teaching, 2010
Poor instruction has been cited as a primary cause of attrition from STEM majors and a major obstacle to learning for those who stay [Seymour and Hewitt [1997]. Talking about leaving: Why undergraduates leave the sciences. Boulder, CO: Westview]. Using a double-blind design, this study tests the hypothesis that the lack of explicit instructions in…

von Aufschnaiter, Claudia; von Aufschnaiter, Stefan – Journal of Research in Science Teaching, 2003
In the literature, learners' cognitive development is mainly discussed with respect to changes in learners' content-dependent knowledge (conceptual change or growth). Additional dimensions of time and complexity may also be taken into account to describe cognitive processes in at least three dimensions. We discuss these three dimensions of…

Taylor, Joseph A.; Dana, Thomas M. – Journal of Research in Science Teaching, 2003
This article describes an exploratory case study of secondary school physics teachers' conceptions of scientific evidence. The nature of teachers' conceptions of evidence was derived from an analysis of data collected from 1 preservice and 2 in-service teachers. Each teacher responded to a series of research prompts in multiple interviews and…
