This courseware evaluation rates the "Grab a Byte" program developed by tne National Dairy Council. (The program--not included in this document--is divided into three sections: Grab-a-Grape uses a quiz-show format to examine students' knowledge of food groups; Nutrition Sleuth reinforces students' nutrient knowledge; and Have-a-Byte analyzes meals in terms of students' nutrient needs.) Part A describes "Grab a Byte" in terms of subjects (food and nutrition) and hardware requirements (Apple II and peripherals), indicates its suitability for 7th-10th grade individual or small group instruction, and lists accompanying materials (instructor and user guides, food list) and time estimate (25-40 minutes). Availability information includes cost ($30.00) and contact address. Part B contains the evaluation criteria in eight categories; reviewer ratings appear as yes, somewhat, no, and not applicable, with explanatory comments. Part C summarizes the evaluation. The strengths of this program are its interesting, easy-to-follow game format and topic. A weakness is that answers are provided too readily in the Nutrition Sleuth section. Summary ratings in the eight categories include the following: subject matter, technical presentation, student interaction, and program interaction--yes; documentation--somewhat; and student evaluation, work behaviors and application programs--not applicable. The final rating highly recommends this courseware as a fun way to learn sound nutrition information. (SK)
