Multiple representations are a valuable tool to help students learn and understand physics concepts. Furthermore, representations help students learn how to think and act like real scientists. These representations include: pictures, free-body diagrams, energy bar charts, electrical circuits, and, more recently, computer simulations and…

Previous studies have shown that people with mild intellectual disabilities have difficulty in "weighing-up" information, defined as integrating information from two different sources for the purpose of reaching a decision. This was demonstrated in two very different procedures, temporal discounting and a scenario-based financial…

The article contains figures that can be photocopied to make the planisphere. (Contains 2 figures.)

The author visited the Galapagos Islands in 2009 and here looks at their biodiversity through pictures taken then. The diverse habitats of the Islands are reflected in the great diversity of flora and fauna found on them, with many species endemic to the Islands. The stories of the land iguanas, control of introduced species and the giant…

This paper describes the creation of a poster for the poster session that was part of the ACRL Science and Technology Section program "Federal Friends: Creating Greater Access to and Support for Science and Technology Information," at the American Library Association Annual Conference in June 2010. Details about the making of the poster up to and…

The author believes that a stimulating learning environment can offer benefits to the general classroom conduct of young people through the different charts displayed in his classroom. Students see the teacher taking pride in their shared working environment and wall or table graffiti. He mentions that he does not only care for his students'…

This article presents a timeline of events, ideas, and technological innovation that provides a foundational historical record on the confluence of teaching and…

What type of display helps students learn the most and why? This study investigated how displays differing in terms of signaling, extraction, and localization impact learning. In Experiment 1, 72 students were assigned randomly to one cell of a 4 x 2 design. Students studied a standard text, a text with key ideas extracted, an outline that…
