Discusses the complicating effects of ambivalence on the validity of science attitude measurement scales. Cites studies indicating that the positive and negative effects about a particular psychological object are not necessarily bipolar. Suggests the use of factor analysis to check dimensionality in instruments. (TW)

Discusses a study which assessed the effect of a brief kinematics unit on: (1) students' ability to translate between a physical event and the graphic representation of it, and; (2) the effect of real-time on graphing skills. Reports the success of the use of a microcomputer-based laboratory with graphing velocity and distance. (ML)

Examines (1) how students evaluate information obtained in the science laboratory; (2) the effects of use of microcomputer-based laboratory; and, (3) the effects of explicit instruction on critical evaluation skills. Discusses results in terms of students' propensity to accept incorrect graphs and in terms of the effect of the enhanced instruction…

This study describes grade 12 students in Israel (N=2277) and examines the relationships between certain background variables and student achievement in science. Discusses findings related to achievement and the variables of gender, major field of study, home background, school-related practices, prior studies, and future intentions. (ML)

Identifies specific science skill activities and discusses how they can be enhanced using the microcomputer in a laboratory setting. Highlights the benefits, advantages, and applications of microcomputers in physics laboratories. (ML)

Reports on a study into the effectiveness of implementing an interactive videodisc science lesson on titration into a high school science program. Describes the titration lesson and the equipment used in two chemistry classes. Results were generated from achievement and attitude instruments, along with observational data. (TW)

Details the features of BASIC used in mathematics programming and provides the information needed to translate between the Apple II and IBM PC computers. Discusses inputing a user-defined function, setting scroll windows, displaying subscripts and exponents, variable names, mathematical characters and special symbols. (TW)

Describes an approach to teaching population genetics and evolution and some of the ways models can be used to enhance understanding of the processes being studied. Discusses the instructional plan, and the use of models including utility programs and analysis with models. Provided are a basic program and sample program outputs. (CW)

Discusses why creation science could be discussed in a high school biology class. Examines the debate that exists between scientific creationists, biblical literalists, and traditional scientists regarding the teaching of creation science in schools. Describes how discussion of this debate could help students understand the nature of science. (CW)

Describes a field trip activity to measure changes in elevation across the dunes of a barrier beach, measure wind velocity along the transect line, and observe the distribution of ground cover in the study area. Discusses equipment, materials, procedures and follow-up activities for each study. (CW)

Lists five experiments or demonstrations involving hypodermic syringes. The titles of experiments are Boyle's Law, Charles' Law, Atmospheric Pressure, Expansion of Gases, and Boiling at Reduced Pressure. Provides a list of materials, the typical data, and graphs where appropriate. (YP)

Presented is the use of a microprocessor for mechanics experiments. Described are the experimental set-ups, experimental method, and conclusions. Includes several diagrams and pictures. (YP)

Reviews a computer courseware package for mechanics at the high school and introductory college level. Discusses one-dimensional collisions, two-dimensional collisions, and simple harmonic motion programs. Shows two typical monitor displays. Rates this program as good overall. (YP)

Describes an introductory chemistry experiment that can be used for lead-in discussions for a variety of topics. Stresses this experiment's ease because of measuring simplicity and familiarity of materials, and its value of reinforcing proper observation and recording techniques while getting students to think about techniques and concepts of…

Decribes a study which compared computer assisted instruction (CAI) with a parallel paper-and-pencil module to assess the impact on students' achievement and attitudes in chemistry. Supports the contention that CAI works as well or better than more traditional methods and tends to promote positive attitudes. (RT)
