The problem of this study was to describe and analyze the computer programming abilities and thought processes of five-year-old children using a conventional microcomputer and the Apple LOGO language. This dissertation reports on the behavior of five kindergarten children and the counts they made as they learned to program in LOGO on an Apple XI Plus microcomputer. The five participants were randomly selected from a group of ten five-year-olds who passed a screening test of numeral and capital letter recognition. The sample included three girls and two boys, all of whom were white. The students met individually with the researcher and the computer for about twenty minutes every day during a ten-week period.
