Discussed is the use of volunteers to teach an astronomy laboratory course. Amateur astronomy groups were recruited to help teach this course. Advantages of using volunteers are listed. A list of student field experiences is included. (KR)

Described is a mobile hands-on science program called "Light Works" that is brought directly into the classroom. The reasons for the implementation of "Light Works" into primary classrooms is discussed. The advantages and operation of this program are included. (KR)

The effect of intervention lessons designed to accelerate the development of formal operations taught over a period of two years to adolescents was assessed. Results indicated that the experimental group had achieved a significantly greater gain in cognitive levels than the control group. Implications are discussed. (CW)

Described is a means of logging data from remote sensors in data files and then transferring the data to a spreadsheet for processing. The presentation of the data in tabular or graphical form is discussed. An example using temperature data from a model house is provided. (Author/CW)

Describes a multiple choice, pencil and paper, diagnostic instrument used to measure student understanding of covalent bonding and structure concepts. Reports evidence of seven commonly held misconceptions. (MVL)

Described is an activity which can be used to investigate heat expansion in a solid. Included are background, materials, procedures, and suggested discussion questions. A diagram of the apparatus is provided. (CW)

Two classroom activities designed to help students learn to distinguish science from superstition are presented. Procedures are discussed and the two activities are compared. (CW)

Discusses the classroom management, instructional design, and interactive grouping of cooperative learning. Lists six of the positive results of cooperative learning. (YP)

Introduces microcomputer interfacing as a method for explaining and demonstrating various aspects of the concept of function. Provides three experiments with illustrations and typical computer graphic displays: pendulum motion, pendulum study using two pendulums, and heat absorption and radiation. (YP)

Identifies some mathematics and science skills required for successful performance in entry-level positions filled by high school graduates and determines if a group of high school graduates in the work force have those skills by using a needs assessment technique. (YP)

Presents abstracts from the National Educational Computing Conference held in Dallas, Texas on June 15-17, 1988. Selected topics include: a physical science interactive videodisc project, impact of calculators and computers in secondary math, relationships between graphing and functions, effectiveness of computer use, training science teachers,…

Presented is a summary of the results of two research reviews on the use of educational technology in the classroom. Criticisms of research methods are discussed. Three centers for research in educational technology are described. Summaries of five specific research reports are provided. (CW)

The use of concept maps, Vee diagrams, flow charts, and productive questions to increase student understanding of laboratory exercises and to improve student attitudes toward lab classes is discussed. Examples of each are provided. Student responses to these teaching methods are described. (CW)

Describes methods for teaching mechanics. Concepts included are force, inertial frames, and rotation. Emphasizes how to feel or observe them. (YP)

Evaluates 5 courseware packages covering the topics of simple harmonic motion, 7 packages for wave motion, and 10 packages for sound. Discusses the price range, sub-topics, program type, interaction, time, calculus required, graphics, and comments of each courseware. Selects several packages based on the criteria. (YP)
