The first of two studies reported was conducted to determine whether unemployed aerospace engineers who received computer science training as well as the Nightengale-Conant attitude change packages would have a significantly higher course completion rate than control classes who were given the same training without the attitude change packages. The experimental class totaled 30. They listened to the Nightengale-Conant tapes and were given class instruction concerning attitudes and goals. Findings showed that Ss benefitted from both the occupational training and the experience of learning to set personal goals and to change attitudes. The second study was conducted to determine whether the application of Nightengale-Conant attitude change packages to low-income, minority community college students would increase their grade point averages and retention rates. Ss were 24 low-income minority students who enrolled in Fall 1972 at San Jose City College and were awarded California Extended Opportunity Program grants in aid. Tapes were checked in and out by student supervisors; little, if any, effort was made to discuss with students ideas on the tapes. Results showed that the GPA and retention rates of these students were higher than the GPA and retention rates of the comparable control group. (KM)
