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)

Reports the positive effects of a school-based program including classroom health education, vigorous physical education, and lower fat and sodium school lunches on improving students' diet and physical activity. However, staff development and policy changes would have to accompany any widespread implementation. (CJS)

Describes a study of undergraduates that examined the effects of behavioral versus cognitive review strategies on learning outcomes and depth of processing during computer-based instruction. Near and far transfer learning are discussed, the use of locus of control is explained, and posttest differences are examined. (eight references) (LRW)

Compares computer-assisted instruction in an online library tutorial with the traditional classroom approach to bibliographic instruction. Results of pretests and posttests were compared with students who did not participate in instruction and it is suggested that further research is needed in the area of confidence levels and library use.…

Compares the use of a print and multimedia program to teach Spanish to second through fifth graders from quantitative and qualitative perspectives. Showed that achievement and proficiency of students using print or multimedia materials did not differ at posttest. A small but statistically significant difference in achievement emerged at the…

Describes the development of Building Family Foundations, 10 competency-based interactive multimedia modules for preparing social workers for child welfare issues they may encounter in professional practice. Discusses results of pre- and post-tests that evaluated the program in terms of students' content knowledge, self-efficacy, and attitudes…

Compares two approaches for preparing students to take standardized reading tests. Discusses study that used a pretest-posttest design with reading-comprehension passages and questions to assess improvement. Suggests that measurable gain in short-term developmental programs may require focusing on a more modest number of teaching objectives,…

We investigated the relationship between three potential markers for reading difficulties (phonemic awareness, verbal short-term memory, and rapid automatized naming) and students' responsiveness to Reading Recovery instruction. At pretest, students' most prevalent weakness was on phonemic awareness, but more than half were below average on rapid…

Design-Based Science (DBS) is a pedagogy in which the goal of designing an artifact contextualizes all curricular activities. Design is viewed as a vehicle through which scientific knowledge and real-world problem-solving skills can be constructed. Following Anderson and Hogan's (1999) call to document the design of new science pedagogies, this…

This investigation was designed to determine the influence of metaphorical priming on students' comprehension of issues and concepts pertaining to the U.S. Constitution when students studied the subject matter in a problem-based hypermedia instructional system. Sixty-five high school seniors studied the system for 5 days after receiving relevant,…
