The purpose of this study was to investigate not only the effectiveness of dynamic versus static visualizations on learning star motions but also the influence of students' spatial abilities with these two types of visualizations on their learning. We assigned 155 fifth-grade students to either a dynamic or a static condition. We used a science…

This paper reviews 12 research-based principles for how to design computer-based multimedia instructional materials to promote academic learning, starting with the multimedia principle (yielding a median effect size of d = 1.67 based on five experimental comparisons), which holds that people learn better from computer-based instruction containing…

The paper describes the procedure model AKUE, which aims at the improvement and assurance of quality and cost efficiency in the context of the introduction of e-learning and the development of digital learning material. AKUE divides the whole planning and implementation process into four different phases: analysis, conception, implementation, and…

In the Singapore primary school Mathematics curriculum, students are taught the model method that uses bar diagrams to visualize the problem structure in a given word problem. When these students progress to secondary school, they learn the algebraic way of solving word problems. Studies (e.g. Ng et al.) have shown that poor bridging of students…

Describes an approach to the design of interactive multimedia materials being developed in a European Community project called ILDIC (Integrated Learning Design in Interactive Compact Disc). The dialog that is needed between technologists and teachers is discussed; and the generic model for learning design used in the project is explained. (11…

Explains courseware abstraction as a method of creating generalized computer assisted learning (CAL) lessons that can then be applied to provide as many concrete examples as desired. Topics discussed include generative CAL; cost efficiency; lesson verification; student evaluation; and factually exhaustive lessons. (nine references) (LRW)

Examines the status, issues, and trends of multimedia instructional support. Presents examples associated with the development of CD-ROMs and interactive Web sites to illustrate important considerations for such development. Some issues considered include: degree of interactivity, performance, accessibility, dependability, and development dynamic.…

This discussion of educational technology and the role of computers is based on the author's experiences with the United Kingdom's National Development Programme in Computer Assisted Learning (NDPCAL). Highlights include curriculum development; teachers' roles; research and development; evaluation; control group experiments; instructional…
