Experimentation with graphical methods for data presentation is important for improving graphical communication in science. Several graphical methods are discussed including full scale breaks, dot charts, and multibased logging. Full scale breaks are suggested as replacements for partial scale breaks since partial scale breaks can fail to provide…

A list of mathematical posters available in England are listed. Addresses and prices for obtaining copies are given together with a brief descriptive comment and a recommended age range. (JP)

This brief guide discusses the mounting of overhead transparencies on frames, the types of mounts, the proper masking for presentation, and the use of overlays. Numerous line drawings provide the reader with a helpful visual reference. (RAO)

Numerous studies indicate that the overhead transparency is an effective means of communicating in the instructional process and is favored by both the instructor and the student because of its flexibility and interest value. This index to overhead transparencies lists over 50,000 main titles and provides information on each about its size and…

The second in a two-volume set on educational overhead transparencies, this volume contains the second half of the alphabetical listing of transparencies by title. It also contains directories of producers and distributors--one alphabetical by code and one alphabetical by name. (PF)
