AbstractThe purpose of this paper is to describe some of the alms and characteristics of the computer course An Introduction to Computer Science via Logo, developed at the Israeli Logo Center, the Technion. The article investigates, in a case study context, the effects of these aims and characteristics on high school learners’ attitudes toward computer programming principles. The effect of class size and socioeconomic status (SES) on these attitudes will also be considered. The findings indicate that after being exposed to the Logo course, learners from low SES backgrounds had attitudes toward programming principles that were at least as positive as, if not slightly more positive than, those of learners from high SES backgrounds. This was the case despite the fact that lower SES students attended larger classes, had lower achievement levels, and initially had lower self-evaluations concerning their own mastery of computer programming.
