Viewing and manipulating three-dimensional (3D) structures in molecular graphics software are essential tasks for researchers and students to understand the functions of molecules. Currently, the way to manipulate a 3D molecular object is mainly based on mouse-and-keyboard control that is usually difficult and tedious to learn. While gesture-based…

Design solutions have become increasingly complex and based on a rapidly growing body of knowledge. In order to articulate a design solution to a client, the graphic use of the design narrative can effectively communicate complex ideas. Two case study interventions were conducted in an interior design program in which students were introduced to…

The authors have developed a computer-based learning module on the unit cell of various types of crystal. The module has two components: the virtual unit cell (VUC) part and the subsequent unit cell hunter part. The VUC is a virtual reality simulation for students to actively arrive at the unit cell from exploring, from a broad view, the crystal…

It is generally accepted that the ability to visualize is an important tool for engineers and technologists especially in engineering graphics. Enhancing the spatial visualization abilities of engineering students has long been a focus of engineering graphics educators. Over the years a variety of test and procedures have been developed to…

This paper chronicles the Teaching Mathematics Using Interactive Videodisk (TMMUIV) pilot project. The project emerged in response to the need to train pre-service teachers in, among other things, the use of mathematics manipulatives. The project now can offer a video database and pilot instructional program that combines full-motion video,…

Previous studies indicate that only 6 percent of the nation's population possess the minimum level of understanding of science and technology needed to function minimally as citizens and consumers. Many educators speculate that scientific illiteracy originates in elementary school classrooms, not from intellectual inferiority, but rather from…

This paper presents a research study of children using on-screen manipulatives (objects represented graphically on the computer screen) in learning mathematics. The paper begins by offering the rationale for the use of manipulatives in mathematics education, an assessment of why manipulatives are not more commonly used in schools, and a discussion…
