A study evaluated the use of computer-based video anchors to increase photograph recognition by two students with severe intellectual disabilities. A substantial increase was made in the number of photographs correctly selected with the computer program with results generalizing to selection of photographs on each participant's augmentative…

Examines key management issues involved in delivering geographic information services on the World Wide Web, using the Geographic Information Center (GIC) program at the University of Virginia Library as a reference. Highlights include integrating the Web into services; building collections for Web delivery; and evaluating spatial information…

Identifies a function generator as an instrument that produces time-varying electrical signals of frequency, wavelength, and amplitude. Sending these signals to a speaker or a light-emitting diode can demonstrate how specific characteristics of auditory or visual stimuli relate to perceptual experiences. Provides specific instructions for using…

Investigates the impact created by the use of videoconferencing technology in a large MIS class where, traditionally, lecture had been used. Even though 85% of the students who participated in the classes were non-MIS majors, students in the videoconferencing section perceived it to be more useful, challenging, attractive, and clear compared to…

Describes an active learning approach used in an introductory biology class and evaluates the project with student surveys. Presents students' answers to survey questions. (Contains 16 references.) (YDS)

This study divided 119 undergraduates into low and high prior knowledge groups and assigned them to three instructional treatments (control, instructor-provided imagery, learner-generated imagery) of the human cardiovascular system. Determined that there was no interaction between student prior knowledge and imaging strategy and that all imagery…

Instructional designers and researchers are attempting to identify the factors that determine which type of graphic visuals to employ in a specific situation as well as how best to utilize available resources. The use of three-dimensional graphics in a variety of media formats is addressed, including a discussion of specific instructional…

Study (35 international students) of the effects of graphics within a computer-assisted instructional program about the rules of American football. Subjects receiving lessons with supplemental graphics received higher post-test scores, completed the test in less time, and reported higher motivation with computer-assisted instruction than those…

Taking into consideration some gaps observed in SLA research--noticing, recasts, input enhancement (IE),…-- and in CALL/CMC research, a study was conducted among 12 advanced FL Spanish learners to assess whether and how, by communicating with a Spanish native speaker in 5 chat-room sessions, their language competence would develop in the following…

The educational aim of this genealogical study of ribbon workers as popular educators is to expose activist and voluntary organisations, not only as generative sites of learning, but also as sites of habituated learning and stereotypical colour assumptions. This study urges popular educators and activists to reflect critically on the popular…

In the study reported here, I examined the diagrams that mathematically capable high school students produced in solving applied calculus problems in which a diagram was provided in the problem statement. Analyses of the diagrams contained in written solutions to selected free-response problems from the 1996 BC level Advanced Placement Calculus…

Poster presentations are one way scientists present their latest research findings at professional meetings. This format also works well in the classroom and gives students the opportunity to communicate the results of their experiments (perhaps the most critical portion of their studies). In a performance-based task such as a poster session,…

A general Web-based system for use in education, the tutor-web, has been developed for storage and presentation of electronic slides for classroom use, along with reference material, examples and quizzes. The primary novelty of the system is the structured linkage between the various pieces of information, to maintain coherence and focus on the…

Visual representations play a critical role in the communication of science concepts for scientists and students alike. However, recent research suggests that novice students experience difficulty extracting relevant information from representations. This study examined students' interpretations of visual representations of DNA replication. Each…

Computer technology can be integrated into science inquiry activities to increase student motivation and enhance and expand scientific thinking. Fifth-grade students used the visual thinking tools in the Kidspiration[R] software program to generate and represent a web of hypotheses around the question, "What affects the distance a marble rolls?"…
