A modified technique for demonstrating the magnitude of Avogadro's number using a new Raspberry Pi computer and the Python language is described. The technique also provides students the opportunity to review dimensional analysis.

This paper advocates the use of symbolic computation packages as another aid in teaching geometry. The need for such packages and their use in computerized proofs are demonstrated by a problem in high school planar geometry. (LZ)

Briefly reviews drill and practice, tutorial, simulation, and computer modeling software for teaching about Europe. Provides titles, names, and addresses of the eight vendors' software featured in this review. (JDH)

A review of BioTutor which is software to accompany the third edition of Neil Campbell's textbook, "Biology," is provided. The review includes a brief description of the software and a discussion of good and bad features of the software. In the closing words, the reviewer expresses a considerable amount of concern regarding the quality of this…

This guide is intended for use in a course to help students become familiar with computer disk operating systems and the applications of various types of computer software.

Describes how a Minnesota high school developed the use of microcomputers throughout every facet of the school during the past decade. (MD)

Discusses the term microworld; develops a conceptual framework to analyze the sense in which the world metaphor may or may not hold; and describes a study of high school physics students working individually with the computer microworld "Elmira" that was conducted to analyze how their thinking was worldlike. (Contains 11 references.)…

Evaluates the technical efficacy of the V-Scope in measuring motion produced by a phonograph turntable, a template furnished by the manufacturer, a free-fall apparatus, some pendula, a gyroscope, and three air tables. Concludes that the V-Scope gives excellent results and is easy to use. (MDH)

The effectiveness of software use alone or in combination with teacher intervention on the acquisition of multiplication facts was evaluated in a study of a 16-year-old male student with a specific mathematics disability. The computer assisted instruction alone produced only transitory effects, while the combined approach resulted in maintenance…
