In recent years, student-generated stop-motion animations (SMAs) have been employed to support sharing, constructing, and representing knowledge in different science domains and across age groups from pre-school to university students. The purpose of this review is to give an overview of research in this field and to synthesize the findings. For…

The vast extent to which quantitative prerequisites vary among post-secondary geoscience programs often presents a challenge for educators and students alike in courses for which math and physics are foundational. This study discusses the design of GEOAppS, a suite of educational numerical models, and its application toward lowering the…

My dissertation evaluates two efforts to improve undergraduate economics education---the College Fed Challenge (CFC) competition and requiring intermediate algebra as a prerequisite for taking introductory economics courses. Using survey data of undergraduate students who participated in the CFC competition and a control group of students who did…

Consumer electronics are creating huge job markets for graduates with the programming back-ground, and more and more computer science departments are launching embedded software subjects to meet this demand. However, most students majoring computer science do not have the background in electronics, or even circuits. Due to this reason, how to…

In this paper the augmentation of worked examples with animations for teaching problem-solving skills in mathematics is advocated as an effective instructional method. First, in a cognitive task analysis different knowledge prerequisites are identified for solving mathematical word problems. Second, it is argued that so called hybrid animations…

Most undergraduates lack the scientific background to read and appreciate much of the primary literature in physiology. Even when the underlying concepts are elegantly simple, the inherent complexity of contemporary papers often makes the work inaccessible to them. However, with a little help, they can be guided to an understanding of the creative…

This article reports on the problems experienced by the Department of Distance Education, Makerere University, Uganda with the B.Ed. (External) programme with specific reference to the technology needs and expectations of the programme. With a total enrollment of nearly 3,500 students in 2003, this programme was one of the largest distance…

Interviews with 18 teachers in high school technical classes indicated that instructional setting demands are very similar to those in general academic classes and pose serious challenges to the literacy and mathematical skills of students with learning disabilities. Special educators are urged to collaborate with technical teachers to apply…

This research review examines the effects of instructional variables on the learning of handicapped and nonhandicapped individuals. The research review begins with an historical look at learning disabilities research. An overall analysis of the differential effects of instructional variables on learning-disabled and nonhandicapped individuals…

Reports results of procedures directed at isolating and identifying students' difficulties in comprehending the concepts involved in lessons about gas exchange and respiration. Indicates that pupils (n=137) had deficient understanding of prerequisite concepts and tended to operate at the concrete operational level, whereas the highly abstract…
