Describes two types of computer-based experiments: simulation (which assumes no student knowledge of the workings of the computer program) is recommended for experiments aimed at inductive reasoning; and modeling (which assumes student understanding of the computer program) is recommended for deductive processes. (MLH)

Examines a number of factors that might influence performance in a college laboratory chemistry course. Compares the achievement and time for students doing a simulated or a laboratory experiment. Tries to identify differences in performance for students of different aptitude and possible interaction between types of experiment and student…

Three variations of computer assisted instruction feedback were used with college astronomy students. On only one measure, a posttest, did subjects' achievement by treatments differ significantly. Significant differences in attitudes according to treatment group were not observed. (CP)

Determined the effect of computer assisted instruction (CAI) materials on college students' attitudes toward computers and chemistry. Includes the finding that the attitude of women toward computers was improved by using CAI.

This study investigated what constitutes exploratory learning and what effects instructional support measures have on it. Among the conclusions were that students were reluctant to apply learning processes that are considered characteristic for exploratory learning. Students had problems with the process, especially with the process of generating…

Presents data indicating that learning can be enhanced when information is presented that illustrates how science information can be used to solve problems. The experiments showed positive results through use of video-based macro-contexts. (ML)

Compared two methods of instruction for improving the computer literacy of preservice elementary teachers (N=94): computer assisted instruction in an earth science course and computer programming in a mathematics education course. Computer literacy was measured by the Minnesota Computer Literacy and Awareness Assessment. Methodology, findings, and…

Beginning physics students (n=42) were constrained to analyze mechanics problems according to a hierarchical scheme that integrated concepts, principles, and procedures. After five one-hour sessions, students increased their reliance on the use of principles in categorizing problems according to similarity of solution and in writing qualitative…

Found that a text mode of programed instruction and tutorial computer-assisted instruction are equally effective modes of instruction for teaching internally- and externally-oriented preservice elementary teachers (N=81) the integrated science process skills. (JN)

Investigated were the effects of interactive computer-generated homework on unit tests, a final examination, and a comprehensive test given near the end of a Physical Science I course. The results indicated that the use of the homework reduced the effectiveness of the American College Test scores as a predictor of course achievement. (YP)

The purpose of this study was to examine the effects of three instructional methods and conceptual systems orientation on achievement in a freshman general chemistry laboratory course. Traditional approach, learning cycle, and computer simulations are discussed. (KR)

Concept mapping with "Learning Tool," a computerized mapping program, was used to assess changes in the content and organization of 17 preservice teachers' concept maps for the topic of effective teaching. This study illustrates how concept mapping can be useful in describing students' evolving constructions of knowledge in a particular…

Reports a study examining the concurrent validity of concept maps as vehicles for documenting and exploring conceptual change in biology. Elementary education science methods students who were instructed on marine life zones showed significant differences on their concept maps on this topic. (PR)

This study addresses the need for research in three areas: (1) teachers' understandings of scientific inquiry; (2) conceptual understandings of evolutionary processes; and (3) technology-enhanced instruction using an inquiry approach. The purpose of this study was to determine in what ways "The Galapagos Finches" software-based materials created a…
