Determined which form of kinetic structure (high or low) and/or micrograph content (unified or varied) was most effective on introductory college biology students' (N=100) achievement of reading micrograph skills. Findings, among others, suggest that high kinetic structure instruction does not affect actual reading micrograph skills, but…

Describes a paper-and-pencil test for high school biology students measuring science process skills, such as developing hypotheses; making predictions; identifying assumptions; analyzing data; and formulating conclusions. Reports some data on reliability and validity of the test. Provides all 35 items of the test. (YP)

Discussed is the conceptualization, development, and formative evaluation of a series of science education videodiscs. The formative data indicated that videodisc programs can enhance the effectiveness of teachers and substantively impact student achievement and attitudes. (Author/CW)

The question of how children solve force and motion problems in computer simulations without explicit knowledge of the underlying physics was investigated. Keystroke sequences made by children were saved and analyzed, and children were interviewed to understand their perception of the relationship between keyboard input and on-screen action. (CW)

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 impact of enhanced observation or enhanced prediction on scientific reasoning about heat energy and temperature problems was investigated. Instruction was successful in improving prediction and observation skills in the microcomputer-based laboratory environment. (CW)

Describes and evaluates science teachers' implementation of microcomputers at a field-test site that was part of a program to encourage literacy of science teachers in the use of microcomputers (ENLIST-Micros). Discusses why only 33 percent of the teachers used computers one year after the training. (Author/YP)
