Designed to instruct both elementary school teachers and students in the practical use of computers, this manual contains 20 sample drill and practice examples of computer aided instructional programs. The programs were written using a TRS-80 Model III microcomputer, but can be adapted to most other microcomputers that utilize the BASIC language. The manual begins with an introduction to the programs, including simple suggestions for starting up the computer, inputting information and saving it, and the use of commands such as NEW, RUN/STOP, SAVE, and HOME. The sample programs include title, purpose of instruction, and a print-out of line numbers, text, and commands for inputting the program. Program titles are: Missing Letters; Guess the Letter; Alphabetical Order--Letters; Alphabetical Order--Beginnings; Alphabetical Order--Words; Ending Sounds; Capitalization; Spelling Test; Punctuation; Addition Practice; Subtraction Practice; Multiplication Practice; Division Practice; Greater Than/Less Than; Reducing Fractions; Fraction Conversion; Grouping Vertebrates; History Sequences; Presidents; and States and Capitols.
