It is now required for teachers to incorporate computational thinking (CT) into their science classes. Our research modifies the existing structure of a science methods course for preservice teachers to include CT via modeling and simulations. In the first study, preservice teachers were introduced to the basics of coding through an Hour of Code…

The purpose of the current study is to explore the impact of associating animations with concrete models on eleventh-grade students' comprehension of different visual representations in organic chemistry. The study used a post-test control group quasi-experimental design. The experimental group (N = 28) used concrete models, submicroscopic…

Two experiments investigating the benefit of computer-based applications in geography education are presented. The computer-based methods employ concepts of visualization, including animation and interactivity, to facilitate active learning. These computer-based methods are compared with physical (i.e. tangible) models, which themselves can be…
