Examples of the use of various kinds of mobile information technology are explained for use in the classroom or laboratory. Individual or group work can make use of such devices, avoiding the need to move the class to a computer room or wait for a turn to use a computer in the laboratory. Many different applications are available. This article…

Extols the virtues of PowerPoint as a teaching aid yet cautions against inappropriate use of it which may cause students to learn very little. Explains a number of features of slide preparation and presentation techniques that enable teachers to give effective lessons. Includes examples of PowerPoint presentations. (Author/NB)

Reviews current research into the use of PowerPoint in instruction and offers guidance for secondary science teachers on how to achieve the best learning outcomes for their students using the program. (Author/NB)

Modeling is important in science and in science education. Computer-based modeling opens up new possibilities for learning science, particularly now that appropriate software is available. This article describes high school students' use of Model Builder software in high school classrooms. (PR)

Discusses the use of a microcomputer in the assessment of middle school pupils in science classes. Describes experimental details, the computer program, test procedures, and results. Concluded that pupils benefit from the immediate feedback provided by computer assessment compared to traditional methods. (CW)

Discusses a new computer modelling system and compares a teaching strategy that uses computers to explore exponential decay with a teaching method employing the Cellular Modelling System in which the monitoring of a real experiment and the development of a model representing the experiment are done at the same time.

States that quantitative modelling allows teachers to concentrate more on qualitative understanding. Suggests the main benefits as (1) repetitive calculations are reduced allowing greater attention to be focused on underlying models; (2) more "what if" models can be tested; and (3) a wider variety of data can be used to test models.
