A one-degree angle would certainly be difficult to draw accurately, especially without the aid of other tools like a protractor. However, mentally making a one-degree angle in visualized imagination is not only possible, but it is important for students' emergent understandings of angular measure. When students begin learning about length,…

The use of visual metaphors has received growing attention in recent years, but their widespread use is not without certain challenges.

This article reviews 3D display…

Stereoscopy's potential as a tool for science education has been largely eclipsed by its popularity as an entertainment platform and marketing gimmick. Dozens of empirical papers have been published in the last decade about the impact of stereoscopy on learning. As a result, a corpus of research now points to a coherent message about how, when,…

We investigated whether and how student performance on three types of spatial cognition tasks differs when worked with two-dimensional or stereoscopic representations. We recruited nineteen middle school students visiting a planetarium in a large Midwestern American city and analyzed their performance on a series of spatial cognition tasks in…

The article discusses problems that arise from comparing different kinds of presentation modes such as texts, pictures or animations with regard to learning outcome. These comparisons are confounded with or depend on other variables like quality of the instructional design, learning content, familiarity with the presentation mode as well as…
