Instructional labs are widely seen as a unique, albeit expensive, way to teach scientific content. We measured the effectiveness of introductory lab courses at achieving this educational goal across nine different lab courses at three very different institutions. These institutions and courses encompassed a broad range of student populations and instructional styles. The nine courses studied ha...

The purpose of this study was to investigate the relative effectiveness of different types of visuals (static and animated) and instructional strategies (no strategy, questions, and questions plus feedback) used to complement visualized materials on students’ learning of different educational objectives in a computer-based instructional (CBI) environment. Five hundred eighty-two (N = 582) under...

Anthropomorphized robots are regarded as beneficial tools in education due to their capabilities of improving teaching effectiveness and learning motivation. Therefore, one major trend of research, known as RobotAssisted Language Learning (RALL), is trying to develop robots to support teaching and learning English as a foreign language (EFL). As more practical studies on materials development h...

Inexpensive software applications designed to teach reading, writing, mathematics, and other academic areas have become increasingly popular. Although previous research has demonstrated the potential efficacy of such applications, there is a paucity of research that compares applications instruction (AI) with traditional teacher-directed instruction (TDI), and the relative effectiveness and eff...

Current teaching strategies mainly follow instructional or constructive pedagogical models. In instructional model learning, contents are authored for teaching and evaluation of a concept. Whilst in constructive model, a student is exposed to the learning environment that allows him to learn new concepts, and his actions provide an evaluation of his understanding of the concept. Manual authorin...

Internet enabled hybrid audio-data collaboration delivers high quality audio over telephone lines and data interaction over packet switched Internet connections, thus distributing the transmission load between two highly accessible but limited bandwidth media. This paper explores the need for hybrid audio-data collaboration and describes two complementary studies comparing the performance and s...

This paper reports the results and insights of an exploratory investigation of the effectiveness of a prototypic virtual problem-based learning (VPBL) exercise delivered via the WWW, that uses Hypermedia Assisted Instructional Technologies (HAIT). The study targeted all first year medical students at a south-central University School of Medicine who were enrolled in the human physiology course ...

We investigated whether augmenting instructional animations with a body analogy (BA) would improve 10- to 13-year-old children's learning about class-1 levers. Children with a lower level of general math skill who learned with an instructional animation that provided a BA of the physical system, showed higher accuracy on a lever problem-solving reaction time task than children studying the inst...
