The use of electronic mail in the science classroom is discussed. Several applications of the use of this technology in the science classroom are described. Optional activities on computer networks are suggested. (CW)

Describes a problem-solving activity integrating a laboratory investigation with a database activity using Appleworks. Presents typical displays of the databases. The objective of the laboratory was to determine the identity of a pure substance by measuring physical properties and searching the database. (Author/YP)

Describes a study designed to assess the effectiveness of 2 science simulation programs for 11- and 12-year-olds in a developing country (Guyana). Computer-assisted learning (CAL) results are compared with results from written assignments, effect size is discussed, gender differences are examined, and ability levels are considered. (14 references)…

Reviews two software packages for the Macintosh series. "Course Builder 2.0," a courseware authoring system, allows the user to create programs which stand alone and may be used independently in the classroom. "World Builder," an artificial intelligence software package, allows creative thinking, problem-solving, and…

Provides a method to use superscripts and subscripts on the screen by using graphics screen modes. Gives two methods and provides a listing of a sample BASIC program. (MVL)

Includes a list of favorably reviewed science and mathematics microcomputer software for instructional use in preschool through grade 12. Developed as an aid to educators in locating programs they may want to preview. (MVL)

Examined student behaviors during laboratory activities and the amount of time involved in each behavior. Approximately 89 percent of the student time was spent interacting with others. The amount of time spent on various activities appeared to be dependent on the nature of the activity and on the make up of the laboratory group. (YP)

Described are two methods which use microcomputers to illustrate the use of the electrocardiogram and the function of the heart. Included are a simulation and a method of collecting live electrocardiograms. Hardware, software, and the use of these systems are discussed. (CW)

Described is a project in which information about the moral issues surrounding tissue transplants was obtained and videotaped for classroom use. Moral positions and possible educational strategies are discussed. Examples of student statements are presented. (CW)

Eight articles are included in this collection. Topics include: multicultural science, teaching science with metaphors, development of a graded assessment scheme in science, relative performance of boys and girls in chemistry, promoting science understanding, formative evaluations, science background of primary teachers, and promoting creativity…

Surveyed 1200 students in a second semester general chemistry course at Purdue. Investigates areas where student and faculty perceptions of the content of chemistry courses differ. Elaborates on each area and suggests explanations for the findings involved. (MVL)

Discusses some of the contributing factors and chemical reactions involved in the production of acid rain, its effects, and political issues pertaining to who should pay for the clean up. Supplies questions for consideration and discussion. (RT)

Uses a modular approach so the Local Area Network (LAN) can be easily dismantled and reassembled for each class. Notes the course is evolving to keep pace with rapid advances in networking technology although only in its second year. Expands the basic LAN through the addition of second generation personal computers. (MVL)

Discusses a device that enables computer images to be projected using an overhead projector. Describes possible uses for the liquid crystal displays (LCD) along with its advantages and disadvantages. Provides several suggestions for purchasing an LCD. (MVL)

Discusses under what conditions computer simulations should be used. Considers the aspects and qualities of computer simulations used in simulating science laboratory experiments. Provides suggestions for selecting or designing simulations. Examines the idea of transfer when using simulations. (MVL)
