Discusses current uses of computers in United Kingdom schools, specifically in biology, chemistry, economics, geography, and physics classrooms. Suggests reasons why teachers are using computers and describes their application for simulations; construction, evaluation, and modification of models; and for academic games. (DS)

Tested were all-verbal or verbal-pictorial presentations followed by either pictorial practice or a control task with 96 undergraduates; results favored pictorial presentation with review. Also tested were effectiveness of pictorial review tasks to a read-twice control with 50 different undergraduates. Pictorial review facilitated performance and…

Described is an attempt to establish a program on chemical demonstrations through the use of workshops and symposia for high school, junior colleges, and university teachers. Included are types of papers presented at the symposia by high school and university teachers, an outline of demonstrative programs, and importance of demonstrative symposia.…

Courseware was developed to facilitate knowledge transfer between lecture and laboratory for general chemistry at the University of Notre Dame (Indiana). One project uses a tutorial strategy. Another uses tool-based courseware for modeling and manipulation of simulated representations of chemical systems; worksheets guide student use of courseware…

Discusses the format of a semester course and provides details about grading, formative assessment, research papers, lecture activities, cooperative examinations, use of spreadsheets, and open-ended laboratory projects. Contains 15 references. (DDR)

The purpose of this investigation was to evaluate the effectiveness of six instructional programs with the aim of alleviating the problems encountered by students in visualizing rotation in molecular diagrams. Models were filmed rotating around the three different axes with different speeds with and without shadows. (KR)

Presented are 29 science activities for secondary school science instruction. Topic areas include botany, genetics, biochemistry, anatomy, entomology, molecular structure, spreadsheets, chemistry, mechanics, astronomy, relativity, aeronautics, instrumentation, electrostatics, quantum mechanics, and laboratory interfacing. (CW)

Discusses criteria that can be used to determine whether it would be effective to integrate computers into classroom instruction. Highlights include improving the quality of instruction; the use of appropriate courseware for difficult subjects, such as algebra and chemistry; drills and practice; improving motivation; and the role and effectiveness…

Describes two chemistry computer programs: (1) "Eureka: A Chemistry Problem Solver" (problem files may be written by the instructor, MS-DOS 2.0, IBM with 384K); and (2) "PC-File+" (database management, IBM with 416K and two floppy drives). (MVL)

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)

Describes two applications of the microcomputer for laboratory exercises. Explores radioactive decay using the Batemen equations on a Macintosh computer. Provides examples and screen dumps of data. Investigates polymer configurations using a Monte Carlo simulation on an IBM personal computer. (MVL)

Described is the use of automated control using microcomputers. Covers the development of the microcontroller and describes advantages and characteristics of several brands of chips. Provides several recent applications of microcontrollers in laboratory automation. (MVL)

Discusses electron spin resonance, a form of magnetic resonance spectroscopy, used to study electronic structure of molecules with unpaired electrons. Studies benzosemiquinone radical anions which are long-lived and inexpensive. Uses a Project SERAPHIM computer program to perform a Huckel molecular orbital calculation. (MVL)

Describes a two-day forensic science course that is offered to eighth grade students enrolled in Science, Mathematics, and Technology Magnet Schools. Provides sample student activity sheets for the course. (Author/RT)

Describes three software packages: (1) "MacMendeleev"--database/graphic display for chemistry, grades 10-12, Macintosh; (2) "Geometry One: Foundations"--geometry tutorial, grades 7-12, IBM; (3) "Mathematics Exploration Toolkit"--algebra and calculus tutorial, grades 8-12, IBM. (MVL)
