Hartelt, Tim; Martens, Helge; Minkley, Nina – Science Education, 2022
Students possess alternative conceptions of many science topics, and these conceptions can act as obstacles for learning scientific concepts. In the field of biology education, students' alternative conceptions of evolution have been widely investigated. However, there is little research on how teachers diagnose and deal with these alternative…

Romine, William L.; Todd, Amber N.; Clark, Travis B. – Science Education, 2016
We developed and validated a new instrument, called "Measuring Concept progressions in Acid-Base chemistry" (MCAB) and used it to better understand the progression of undergraduate students' understandings about acid-base chemistry. Items were developed based on an existing learning progression for acid-base chemistry. We used the Rasch…

Heddy, Benjamin C.; Sinatra, Gale M. – Science Education, 2013
Teaching and learning about complex scientific content, such as biological evolution, is challenging in part because students have a difficult time seeing the relevance of evolution in their everyday lives. The purpose of this study was to explore the effectiveness of the Teaching for Transformative Experiences in Science (TTES) model (Pugh, 2002)…
