It is essential for introductory level chemistry students to understand atomic models and how atoms interact to form chemical bonds. The tactile model in this article utilizes marbles to represent subatomic particles, a cup to represent the nucleus and wooden rings to simulate the electron orbitals. These inexpensive items can be combined to…

This paper is about "augmented reality" (AR) and its potentials to support students in handling scientific representations. For this purpose, first representations are examined from a science educational and instructional psychology perspective. After giving a short overview of AR in general and how it can be delineated from…

Writing and balancing equations of chemical reactions is one of the most difficult elements of chemistry education for students, which is why it was decided to analyse part of the process which is the most difficult. The process itself consists of multiple stages. it is important to highlight that the focus of research was not only on balancing…

In this study, it was aimed to investigate the effects of microscope simulation software on prospective science teachers' laboratory achievements, microscope use, laboratory reports and views on microscope which was prepared for general biology laboratory. The case study design was adopted for the research. The participants were 49 science teacher…

This project originated with the desire to offer general biology students a laboratory experience which emphasizes scientific thinking rather than a review of lecture content. To create investigative laboratories without many of the practical problems of their implementation, this project uses a combination of "methods modules" for…

Describes the effects of one computer program used in a nonmajors biology course to provide a model for implementing and validating the use of software programs that incorporate tutorials with laboratory simulations. (Contains 27 references.) (MDH)
