A practical focusing on the synthesis, isolation, and hydrolysis of ammonia borane (AB), H[subscript 3]N·BH[subscript 3], was developed for first-year undergraduate students. By requiring students to propose their own experimental setup to measure the amount of gas produced upon hydrolysis, experimental design skills were introduced and developed…

Suggests a starting place for formal inquiry into distance education. Topics covered include: background on educational research and research on distance education; research paradigms that are applicable to distance education; subsystems of a distance education program; and a matrix for conceptualizing distance education research. (MES)

This paper deals with the design process of a remote laboratory for labwork in chemistry. In particular, it focuses on the mutual dependency of theoretical conjectures about learning in the experimental sciences and technological opportunities in creating learning environments. The design process involves a detailed analysis of the expert task and…

This study, conducted by the Basic Research and Implementation in DevelopinG Education Systems (BRIDGES) Project, demonstrates a relatively inexpensive way for governments to increase the effectiveness of their teaching force. The report describes distance teacher education programs in Sri Lanka and Indonesia as being cost-effective (the low…

A research project called Support Services for Flexible Delivery was commissioned by the Australian organization TAFE (technical and further education) Frontiers. Since 1995, the project has been conducted by using a research approach called the Generalizations from Case Studies (GCS) research method. The GCS method was developed, tested, and…

Design-based research is proposed as a strategy to address the need for innovation in educational contexts. The article argues the case for increased and more effective research and development in education, and then presents a discussion of design-based research as a methodological set of tools to address this need. The four phases of…
