Changes in attitudes of learners when programed instruction is interpolated between two conventional instruction experiences.

5parallel forms of a 26-item Likert-type attitude scale were administered in counterbalanced order to 70 airmen studying radiation detection and 53 airmen studying camera repair. Both courses included several wk. of lecture, a programmed unit, and several more wk. of conventional instruction. Students' attitudes were significantly more favorable during the programed unit in both courses. Changes were considerably more pronounced for the 17 highest ability students. (15 ref.)
