The present study describes the development and field testing of a simple apparatus-based diagnostic instrument (SABDI) that examines undergraduate students' understanding of the underlying physics principles that explain how simple acoustic apparatuses work. SABDI comprises 13 items. Based on previous research studies and the history of science,…

Background: Although teaching nature of science (NOS) has been continually emphasized in many major reform efforts in science education, researchers claim that students do not possess adequate views of NOS. Insufficient understanding of NOS can be associated with the ineffectiveness of curricular or instructional approaches. Consequently,…

Most undergraduate chemistry courses and a few high school honors courses, which focus on physical chemistry and quantum mechanics, are highly mathematically-oriented. At the Technion, Israel Institute of Technology, we developed a new module for high school students, titled "Chemistry--From 'the Hole' to 'the Whole': From the Nanoscale to…
