The usability of interactive whiteboards vs. computers was evaluated on three dimensions (visibility, legibility and comprehension) in the secondary school pupils. The visibility assessment consisted in detecting a visual stimulus varying in luminance using a staircase procedure, legibility was assessed with a target-search task, and we…

The purpose of this study is to develop a new approach and assess the application for the science and technology student-teachers to gain varied laboratory methods in science and technology teaching. It is also aimed to describe the computer-assisted POE application in the subject of "Photosynthesis-Light" developed in the context of…

This study proposed a novel instructional approach, a two-stage LED simulation of Project-based learning (PBL) course with online peer assessment (OPA), and explored how to apply OPA to the different structured problems in a PBL course to enhance students' professional skills in LED design as well as meta-cognitive thinking. The participants of…

A method is described for building a cost effective digital circuit capable of monitoring the solar radiation incident upon a remote solar cell. The circuit is built in two sections, the first, digitises the analogue voltage produced by the solar cell at a remote location and transmits the received signal to the second receiver circuit which…

Explores the potential of the RAY learning environment in improving learning about optics. Results indicate that this environment, which includes a flexible ray-tracing simulation, had a significant effect on the spontaneous and correct use of the model by students in solving problems and a limited effect on conceptual understanding, but promoted…
