Describes a study conducted in a Hong Kong primary school that compared the effects of learning LOGO programing with a process-oriented approach and a content-oriented approach to problem-solving skills. Transfer of training to nonprograming problem solving is discussed, and instruments used to assess students are explained. (33 references) (LRW)

Describes a study of undergraduates studying genetics that compared the effectiveness of a computer simulation used before and after formal instruction. Treatment of the experimental and control groups is explained, and results are reported which support the theory that the effectiveness of the simulation is dependent on the sequence of…

Describes a study of novice and advanced preservice teachers that explored the effect of a computer simulation on decision-making training for planning lessons. Treatments of the experimental and control groups are described, results of pretests and posttests are analyzed, and further research is suggested. (14 references) (LRW)

Discusses the integration of different media and describes Bunkyo Museum of Literature, a hypermedia system developed in Japan. A study that tested the instructional effectiveness of the system with college students is described, including results related to level of interest, learning of factual information, and degree of perceived participation.…

Describes a study of undergraduates at Iowa State University that tested the effectiveness of a computer simulation of electric circuits used in combination with a conceptual change approach to science instruction. Erroneous preconceptions of scientific concepts are discussed, and the use of traditional text is compared with conceptual change…

Describes design and evaluation of an instructional video for use with low-achieving junior high school students in Trinidad and Tobago. A moderate level of learning with the video is reported, and further work on targeting learning needs of the mainstream population and facilitating learner capability to link information is suggested. (19…

Objectives of this study were to create a prototype of an interactive hypermedia textbook and to explore the relationships between learners' performance and use of available learning tools (i.e., textbook glossary and navigation map). The effects of prior knowledge on textbook use and performance were also investigated. (11 references) (EA)

A study examines the influence of a Sunship Earth education program on fifth and sixth grade students (n=578). Results indicate that students who attended the program increased their ecological knowledge significantly. Participation did not result in more positive environmental attitudes. (17 references) (MCO)

Describes the use of concept mapping (CM) in design, instruction, and assessment related to microbiology lessons prepared for high school students in Israel. Indicates that students utilizing CM displayed an overall, higher achievement gain than students in traditional classes. Recognizes that some teachers did not thoroughly exploit the potential…

This study focuses on secondary students' (n=79) understanding of ecological concepts and the influence of field instruction strategies on their understanding and retention. Results indicate all groups exhibited statistically significant posttest gains and showed evidence of retaining the targeted concepts. (Author/MCO)

The effects of variations in learner control were examined for an interactive lesson presented as a videodisc visit to an art museum. The 101 first and second grade subjects were assigned to program control, learner control, and learner control with advisement conditions, or to a control group. Data on achievement and curiosity were analyzed. (28…

Effects of animated presentations and practice were studied in a computer-based science lesson involving 55 fourth graders and 64 fifth graders. Results suggest that animated graphics can promote learning, and they demonstrate successful application of interactive graphics in the design of cognitively based practice activities. (SLD)

Discussion of hypertext structures focuses on three studies of preservice teachers that assessed the effects of different methods of explicitly mapping expert knowledge structures onto hypertext on the acquisition of structural knowledge. Topics addressed include time on task, semantic networking, cognitive limitations of browsing behavior, and…

Describes a study that tested the applicability of the Tennyson-Cocchiarella concept teaching model for undergraduate nursing education, and investigated the effects of three different learner control strategies on concept learning. The computer-based concept lesson used is described, and effects on recall and retention are discussed. (33…

Reported is the evidence of significant changes in a university faculty's practices and attitudes toward uses of instructional technologies and active learning strategies for undergraduate mathematics and science instruction after a one-year project. (JJK)
