This article describes a computer simulation of bacterial physiology during growth in a chemostat. The program was designed to help students to appreciate and understand the related effects of parameters which influence plasmid persistence in bacterial populations. (CW)

Two alternative representations for the concept of common multiples are presented. These representations can be modeled on or off the computer. (PK)

Contains six abstracts of papers from the National Educational Computing Conference of 1986. Topics of the papers focus on the effects of teacher involvement, computer programs in applied mathematics and physics, microcomputer labs in science, graphing misconceptions, science simulations, and mastery learning with computers. (ML)

A study was conducted to assess effectiveness of a computer simulation which exposed students to three levels of real-life research situations as laboratory experience accompanying graduate level research design course. Simulation effects on achievement, perceived research competence, interest in research, and effects of differing amounts of…

Defines computer literacy and describes a computer literacy course which stresses ethics, hardware, and disk operating systems throughout. Core units on keyboarding, word processing, graphics, database management, problem solving, algorithmic thinking, and programing are outlined, together with additional units on spreadsheets, simulations,…

The JASON Multimedia Science Curriculum (JMSC) was developed in 1989 by the JASON Foundation for Education (www.jason.org), and is a multimedia, interdisciplinary, inquiry-based science curriculum that responds to the dual demands of teachers having to teach state standards while engaging students in scientific inquiry. The JMSC encourages…

We report the findings of an empirical analysis of the performance of a group of middle and high school students before and after an after-school algebra enrichment program using the SimCalc software incorporating classroom networks. The results highlight statistically significant gains in their learning and briefly outline contributing factors of…

In a project designed to provide training for entry-level job skills in high tech industries, a combination of narrative and technology was employed to aid learners in developing the necessary soft skills (dependability, responsibility, listening comprehension, collaboration, et cetera) sought by employers. The EnterTech Project brought together a…

Discussed is the concept of mirroring in which computer programs are used to enhance the use of mathematics manipulatives. The strengths and weaknesses of this approach are presented. The uses of the computer in modeling and as a manipulative are also described. Several software packages are suggested. (CW)

Provides a listing of a software graphics program that investigates the law of reflection and Snell's law of refraction. Written in BASIC for the Apple II personal computer. (MVL)

Describes a program which allows students to identify and characterize several kinetic inhibitory mechanisms. Uses the generic model of reversible inhibition of a monosubstrate enzyme but can be easily modified to run other models such as bisubstrate enzymes. Uses MS-DOS BASIC. (MVL)

States there is little direct evidence that the current laboratory instructional method is an important component of chemistry instruction. Provides a historical account of laboratory work. Studies individual work versus demonstrations, and computer simulations. Urges the use of computer based methods to provide a rich laboratory experience. (MVL)

Describes an activity that combines manual and computer simulation of a population undergoing selection using three alternative genetic models. Discusses procedures used, model and how the computer simulation works. Stresses the advantage of using the student involvement of the manual exercise in combination with the speed of the computer…

The results of an experiment in teaching engineering graphics using the traditional lecture-homework-laboratory technique are compared to a newer lecture homework proposal. Although the newer method reduces professor-student contact, it may prove to be as effective as the older method requiring laboratory instruction. (KR)

Biology knowledge and understanding is important not only for the conversion of the loftiest dreams into reality for a better life of individuals but also for preparing secondary pupils for such fields as agriculture, medicine, biotechnology, and genetic engineering. But a recent study has revealed that many aspects of school science (biology…
