In each of three studies, students using computer assisted instruction for supplemental drill and practice in a first organic chemistry course performed consistently higher than control students on sections of the course examinations related to the content of the programs. (AL)

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)

Examines college students' perception of an interactive videodisc learning system as an alternative to the conventional laboratory for learning biology skills and concepts taught under classroom laboratory conditions. Reports that the videodisc instruction gave more experimental and procedural options and more efficient use of time than the…

The purpose of this study was to analyze the effectiveness of long-term, tutorial-type computer assisted instruction (CAI) in high school chemistry. Analysis showed scores of non-CAI students significantly higher than the CAI group. However, CAI students learner material faster. (PS)

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)

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…

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)
