Recent increased interest in computational thinking poses an important question to researchers: What are the best ways to teach fundamental computing concepts to students? Visualization is suggested as one way of supporting student learning. This mixed-method study aimed to (i) examine the effect of instruction in which students constructed…

Electrochemistry is found to be a difficult topic to learn due to its abstract concepts that involve three representation levels. Research showed that animation and simulation using Information and Communication Technology can help students to visualize and thus enhance students' understanding in learning abstract chemistry topics. As a result, an…

Discusses the merits of three familiar classroom tools: overheads, whiteboards, and television monitors. Notes that each of these different tools offers a different means by which to introduce ideas and information, illustrate connections, and organize information. Concludes that using resources is important in the light of cutbacks many teachers…
