Problem solving is an essential skill in the study of genetics. Genetics problems have traditionally come from laboratory activities and textbook situations. Recently computer-based problems have been available to complement these standard sources. This report focusses on the use of computer-based problems in the study of genetics. Discriptions…

The Systems Thinking and Curriculum Innovation (STACI) project is a multi-year research effort intended to examine the cognitive demands and consequences of learning from a systems thinking approach to instruction and from using simulation-modeling software. This study tests the potentials and effects of integrating the systems approach into…

Analogy is widely considered to be an important mechanism of scientific thinking and a source of creative insight in theory development. In this paper the implicit constraints that determine analogical soundness are considered. It first examines the constraints that govern analogical reasoning as it is predicted today. The scientific uses of…

Models of the motion of an object through space are discussed. The material begins with the simplest view possible in which gravity is the only force examined. Discussion progresses to an examination of the drag force, which is the resistive air force of the wind. Suggestions for further improvements are made at the conclusion of the presentation.…

This paper describes a model for the adolescent's understanding of the motion of objects, and the application of this model to the design of beginning physics instruction in mechanics. Students' difficulties in learning classical Newtonian mechanics are described and integrated into current cognitive science research. Research findings on physics…

Offers perspectives and specific ways of developing and nurturing critical and creative problem-solving skills with engineering students. Provides examples of exercises and approaches that aim in stimulating creativity and in providing understanding of course material. (ML)

Describes an introductory geology course for non-science majors that focuses on problem solving and group dynamics at The Ohio State University. Reviews its format and contents and compares it with other course options for non-science majors. Includes evaluative comments and provides a listing of group studies project topics. (ML)

Describes a student learning activity used to teach the meaning of percentage composition, mole concept, selective precipitation, and limiting factors. Presents two word problems and their solutions. (CW)

Discusses a study that examined which reasoning patterns are necessary for success in high school chemistry. Based on student (N=170) scores from the "Classroom Test of Formal Reasoning," it was revealed that students who use formal reasoning patterns are capable of greater achievement in chemistry. (ML)

Explains how self-produced software can be used to perform rapid number analysis or number-crunching duties in geology classes. Reviews programs in mineralogy and petrology and identifies areas in geology where computers can be used effectively. Discusses the advantages and benefits of integrating department-generated software into a geology…

Offers a way of teaching quantitative thinking through a software program called, "Hot Dog Stand." This simulation provides students with practice in planning expenses, in computing problems, and in dealing with a situation in which outcomes depend on random events. Also includes suggestions for computer use during non-scheduled time. (ML)

Describes an interactive, self-prompting BASIC program that can be incorporated in introductory and intermediate hydrology courses. Exlains how the program can be used to evaluate pumping test data and also to calculate transmissivity and storativity values of confined aquifers. The program is written for the IBM PC. (ML)

Describes three microcomputer programs that allow geology students to deform two-dimensional images on a computer screen and then to measure changes in angular relationships. Two of the programs simulate pure and simple shear and the third simulates variations in shear strain that occur in shear zones. (ML)

Describes an audiovisual teaching unit on the chemical laboratory technique of recrystallization which was developed along problem-solving lines and based on observation of student laboratory behavior. Discussion includes usual procedures for developing such units, how this unit solves problems typically associated with teaching, and its general…
