Education is an active process in which instructors apply various devices to make the material to be taught more suitable for students' perception. As the capabilities of available devices improve, so should the methods of teaching make the best use of them. No tool can ever replace an instructor, but tools can enhance the efficiency of…

Describes the development of the microcomputer-based educational software, DNAzoom, which was designed to introduce undergraduates in molecular biology to computer analysis of DNA protein sequences. Highlights include graphical presentation of data, the functional use of color, a menu-oriented interface, and students' evaluations of the software.…

Describes an interactive computer program, COLOR-TEST, that was developed at the Technical University of Sofia (Bulgaria) to teach color harmony and color coordination to industrial design students. A brief evaluation of the program is presented, and further developments for the program are suggested. (nine references) (LRW)

Describes: the chemical history of a pencil; a simple solar camera for measuring the sun's diameter; the experimental comparison of the thermal stability of metal carbonates; and the introduction of the concept of weight as a force to young children. A computer program listing on color mixing is also provided. (JN)

Describes microcomputer-based courseware designed for the simulation of the microbiological analysis of drinking water, including digitalized color images. The use of HyperCard is described and evaluation procedures are explained, including evaluation of the learning and of the class. The evaluation questionnaires are appended. (20 references)…

Describes the development of interactive, multimedia courseware based on Josef Alber's book, "Interaction of Color." Alber's ideas and teachings on the perceptions of color are explained, and steps involving computer graphics, hardware, and software that resulted in the use of CD-ROM and videodisc with an Apple Macintosh II are detailed.…
