Presents a model for solving genetics problems when problem statements include information on which alleles are dominant/recessive and on what forms of a trait are coded for by the alleles. Includes procedural steps employed in a solution and conceptual knowledge of genetics/meiosis allowing students to justify what they have done. (Author/JN)

An instructional system at the University of Maine (Orono) was developed to address problems unique to this institution. The system consists of biology instructional modules, variable pacing through computer-generated examinations, and variable credit. Although lectures were initially eliminated, they were reinitiated to motivate students and help…

Describes steps for in-house production of Super-8 mediated learning packages for automotive and life science courses. The individualized instructional format of the packages encourages student interaction, provides hands-on experience in skill development, allows students to proceed at their own pace, and enables students to enter a course at any…

Describes an experiment simulating a real-life structure elucidation problem through isolation, characterization, and chemical transformation of an "unknown," naturally occurring monoterpene, with extensive use being made of spectroscopy and aided by biogenetic considerations. Information given to students, procedures, results, and discussion of…

Uses of Zenith Z-100 microcomputers by chemistry students at Clarkson College are discussed. These include: (1) programing; (2) word processing; (3) numerical methods, statistical/plotting programs; (4) laboratory data acquisition and manipulation; (5) simulations; (6) computer assisted instruction; and (7) computer managed instruction. (JN)

Investigated development of propositional logic and three formal logical schemata (underlying generic problem solving processes/operations) in adults (N=59) enrolled in their second year of medical school. Two students were formal on the 12-Piagetian tasks used, and the 57 remaining were classified as transitional formal. Implications are…

Discusses experiments involving classical conditioning of planarians. Suitable for advanced high school students or college-level independent study, flatworms are trained to curl up under a bright light. Then the planarians to are subjected to controlled reproduction experiments to determine whether the learned behavior is inherited by their…

Outlines a course in which toys are used to demonstrate physics concepts, stressing available or easily constructed toys. A recent lecture sequence included toys demonstrating equilibrium, force/torque, linear/angular momentum conservation, energy conservation/storage, flying, vibrations, programed music, and others. Illustrations of selected toys…

The construction of a homemade Kelvin water-drop electrostatic generator is suggested as an activity for teacher workshops. Materials needed before the workshop and instructions (including a diagram) for preparing the generator are provided. Suggested questions to pique workshop group's curiosity are also provided. (JN)

Reviews software for college/advanced high school-level physics designed to instruct/test students in vector arithmetic and analysis. Written for Apple II/II+ (Applesoft), the program menu contains seven items (including graphing and straight line fitting procedure). Excellent use of graphics and sound tutorial approach keep students' interest and…

Reviews "Laws of Motion" computer program produced by Educational Materials and Equipment Company. The program (language unknown), for Apple II/II+, is a simulation of an inclined plane, free fall, and Atwood machine in Newtonian/Aristotelian worlds. Suggests use as supplement to discussion of motion by teacher who fully understands the…

Discusses college and university learning resource centers, emphasizing the use of computer-based materials in the centers. Topics/issues addressed include advantages of computer use, lack of suitable materials, material evaluation, and criteria for good computer-based learning materials. (Author/JN)

Theses proposed in C. P. Snow's book "The Two Cultures," including uncommunicative scientific and literary groups, gap between rich and poor, overpopulation, and nuclear war remain viable topics. Discusses the scientific and literary cultural gap and what can be done in general studies science courses to ameliorate the condition.…

Describes instructional strategies used in a biology program to develop students' knowledge of biological concepts and skills needed to interrelate and apply the concepts. Discusses student progress in developing desired skills, (using pretest/posttest scores) examining these variables: major (major/nonmajor), sex (male/female), and high school…

Although the landscape may be examined without background information, one's appreciation increases by using resources to interpret changing landscapes. Many geologic maps and road guides have been published for this purpose. The use of one such guide is described and sources of specific guides and maps are included. (Author/JN)
