The video "A Private Universe" evokes surprise and dismay among educators and scientists by demonstrating that even the brightest students fail to grasp a seemingly simple and fundamental concept--the reason for seasons. This literature review describes the findings of 41 studies that collectively illustrate why the concept proves difficult to…

Describes a computer program presenting four genetics problems to monitor the problem solving process of college students. Identifies three main areas of difficulty: computational skills; determination of gametes; and application of previous learning to new situations. (Author/YP)

The Educational Technology Center (ETC) Complex Systems Project was initiated to explore ways of using computers to help students understand systems which have often proven too complex for most high school students to understand. Preliminary work concentrated on the cognitive processes involved in modeling simple systems. This paper describes an…

Investigated the appropriateness of microcomputer-based laboratories (MBLs) for elementary school students. Reports that children expanded their repertoire of graph-making and interpreting skills and MBLs supported scientific inquiry for and by the children. (28 references) (Author/JRH)

Describes an intelligent tutoring system named MENDEL, including problem GENERATOR, TUTOR, student MODELER, ADVISOR, hypothesis CHECKER, and problem SOLVER. This software may be used by high school or university biology students as a tool for learning concepts and problem-solving strategies in transmission genetics. (YP)

Evaluates the attributes of a microcomputer software package as a supplement to chemistry instruction. Reports higher scores among the students in a control group. Discovers no significant interaction between treatment and development stage. Discusses several implications for further research. Provides the General Chemistry Test and error analysis…

Graphs of objects in motion are frequently used in introductory high school or college physics courses since they offer a valuable alternative to verbal and algebraic descriptions by offering students another way of manipulating the developing concepts. If graphs are to be a valuable tool for students, then the level of the students' graphing…

The Scientific Theory and Method Project (STAMPS) is concerned with students' understanding of two areas of science in secondary schools. One is understanding what a scientific theory is, and the other is understanding the methods used in conducting scientific research. In the science curriculum these topics are often described as the process of…

Describes a research strategy designed to examine learning and behavior when students interacted with microcomputers and software interfaced with a videotape cassette recorder (VCR). Utilized the VCR to record the video output from the microcomputer and students' verbal comments using a microphone unit. (TW)

Discusses a microcomputer-based laboratory (MBL) study (n=75) which uses multiple temperature gathering devices (mercury thermometer, digital thermometer, and computer probe) and graphing methods (hand graphs, delayed computer graphs, and real-time graphs). Reports that MBL real-time graphing provides significant increases in graphing skills. (MVL)

This paper is a summary of much of the available research on college science laboratory instruction of the past decade with a focus on the effects of specific laboratory teaching strategies upon student learning outcomes. Some tentative interpretations from a review of the literature found are: (1) inquiry or investigative approaches in college…

Describes two computer programs for chemistry: (1) "A Microcomputer Simulation of Fractal Electrodeposition" (provides for the study of fractal aggregrates, BASIC 4.0); and (2) "Counters on Grids" (a game to illustrate the distribution of energy). Notes the programs are available from the authors. (MVL)

The Educational Technology Center (ETC) has devoted the last five years to studying ways of using the computer and other information technologies to teach understanding in science, mathematics, and computing in the nation's elementary and secondary schools. The Center's research has focused on targets of difficulty, topics and concepts that are…

This volume presents a compilation and review of more than 400 research studies on science teaching and the preparation of science teachers that were reported in 1988, organized into 10 sections. The sections are: (1) "Professional Concerns"; (2) "Teacher Education"; (3)"Programs"; (4) "Curriculum"; (5)…
