Designed to aid teachers, school administrators, librarians, students, and parents in selecting educational software for preschool through grade 12, this guide lists 231 programs chosen from 6,000 evaluations conducted by 35 education software evaluation efforts in the United States and Canada. The introduction provides a detailed explanation of how the programs were selected, and the first of four major parts of the guide presents an alphabetical listing by title of the 185 highest rated programs as well as a listing by the following subject areas: arts, college entrance exams, early childhood education, foreign language, health education, language arts, mathematics, problem solving, science, social studies, student helpers, tool programs, and typing. The description for each of these programs includes the subject area, the copyright date, grade level(s), hardware requirements, cost, type of program, a brief description, teaching tips, a summary of evaluation conclusions, and bibliographic citations for several reviews that appeared in magazines. The second part lists 46 "alert" or "highly promising" new programs that had fewer excellent or good evaluations than the highest rated programs. The 158 highest rated programs in 1989 are listed alphabetically within subject areas in the third part. Each listing includes the producer, computer requirements and price, grade level(s), and copyright date. The final section provides the names, addresses, and telephone numbers of the producers of software listed in this edition. (BBM)
