Describes a "no-cost" apparatus designed to demonstrate rotational inertia. Also describes and evaluates a microprocessor-based instrument (Versatile Laboratory Aid) that performs a large variety of timing and data acquisition tasks encountered in introductory and advanced physics laboratories. (JN)

Outlines various misconceptions about problem-solving (PS) and several strategies to improve intellectual skills and strategies. Also describes the Covington Productive Thinking Program (designed to help develop PS skills) and several lesson problem sets from this series of 15 books. (JN)

Organic chemistry students (N=64) completed questionnaires requesting demographic data; data on ability, previous science courses, attitudes toward self when studying chemistry, attitudes toward chemistry; and preference, difficulty, and importance of chemistry compared to other courses. These data are used to develop a profile of the successful…

Lists postulates on which the author bases his approach to large class instruction. Suggestions are given for such administrative, operational, and academic procedures as organizing handouts and class information; avoiding "busy work"; finding out about the students (personal and academic); making an assignment due every class; and providing quick…

Hypothesizes that overloading the working memory may leave no space for thought and organization such that faulty (or even no) learning takes place. Provides examples of this hypothesis and possible remedies. These remedies focus on design of laboratory manuals and equipment and on curriculum content order. (JN)

Describes technology-oriented courses or programs at five institutions of higher education. Course/program objectives and format, instructional strategies, and types of learning experiences offered to students are considered. (JN)

Describes an apparatus which demonstrates the stability of equilibrium of multidimensional objects and helps students to understand the concept of a lever arm. Also describes an alternative to the standard black, mercury "student cell" used as a reference voltage for calibrating a slide-wire potentiometer. (JN)

Recommends an experiment which will help students experience the physical evidence that floors, tables, and walls actually bend when pressure is exerted against them. Set-up includes: laser, radio, solar cell, and wall-mounted mirror. When the beam is moved by pressure on the wall, participants can "hear the wall bend." (DH)

Lists 15 commonly encountered misconceptions/misunderstandings in biology, together with specific suggestions to help teachers and textbook authors clarify each misconception. Included are problems related to understanding differences between acellular and multicellular, respiration and photosynthesis, egestion and excretion, and homeostasis and…

The expected thrust for theoretical chemistry in the next decade will be to combine knowledge of fundamental chemical steps/interactions with advances in chemical dynamics, irreversible statistical mechanics, and computer technology to produce simulations of chemical systems with reaction site competition. A sample simulation (using the enzyme…

Discusses the diversity and dynamic nature of the chemical components of postharvest crops. Also discusses the role of respiration and genetic control in chemical transformations leading to desirable and undesirable changes in the quality of edible plants after harvest. The role of enzymes in producing these changes is considered. (JN)

Describes an easily constructed, small laboratory computer that can be programed in BASIC. The computer is easy to use with analog to digital and digital to analog converters so that it can serve as a control or data logging computer. (Author/JN)

Investigated relationships between visual-spatial abilities and achievement and what influence these abilities have on the high attribution rate characteristic of many introductory college-level science courses. Results, among others, using physics students (N=136) and nonscience majors (N=52), indicate that visual-spatial abilities influence…

Discusses remote sensing principles and applications and the status and needs of remote sensing education in the United States. A summary of the fundamental policy issues that will determine remote sensing's future role in environmental and resource managements is included. (Author/BC)

Describes an attempt to facilitate the learning of biology by students with poor reading skills through the integration of computer-assisted-instruction with a classical audio-tutorial biology course. Results indicate that performance of poor readers can be improved when they are provided with updated advisement information about their achievement…
