Adopting new instructional materials is an important way to support reform in science education, but implementation can be challenging and complex. Therefore, we conducted a contrasting case study of two middle schools implementing new curricular materials. We conducted semi-structured interviews with teachers and leaders and collected…

Quantum mechanics is an integral course for physics students. An understanding of quantum concepts is imperative for enrollment in physics graduate programs, participating in research within physics fields, and employment with companies developing quantum technologies. This study analyzes 188 U.S. research-intensive institutions' course catalogs…

The FCE (field-based chemistry experiment) model was developed to cultivate pre-service science teachers' ability to teach chemistry experiments in secondary classrooms. We describe the process of developing the FCE model and student activities via feedback from experts and analysis of the implemented program. This study evaluated the…

Representations have been widely applied to teaching and learning in Western classrooms and recently in several Asian countries. More and more Asian schools are calling for the application of this approach in teaching science. However, little has been known about how the construction of representations could enable teachers to make changes in…

This article argues that what is most at risk in schooling during a global pandemic, or other similar broad challenges to normal functioning, are those elements that might be considered the less traditional and so the most progressive. After setting out some general background common to the challenge faced by schools and school teachers, this…
