The impact of growing numbers of personal computers at Dartmouth College was assessed. During one academic year (1984- 1985), the number of personal computers (mostly Macintoshes) grew from less than 50 to almost 2,000. The assessment focused on three areas: purchase and admissions data, student life, and the curriculum. Tentative findings include: blacks and females bought Macintoshes at significantly lower rates than did whites and males. These same groups also made less use of other campus computing resources. Students who purchased Macintoshes had higher quantitative scores on the Scholastic Aptitude Test (SAT) than nonbuyers but there were no differences in verbal SAT scores. Students seemed to like their Macintoshes; they used them primarily for word processing and they believed that their performance had improved by having one. Student communications improved greatly as a result of the personal computers. Faculty and students felt generally positive about the effect of the Macintoshes on the curriculum, but there was no evidence that the amount of learning had increased in courses using the computers. Statistical findings and the study questionnaire are appended. (SW)
