The effects of a 14 week creativity training program (the Purdue Creative Thinking Program) on the creativity in written expression of 25 learning disabled (LD) students (11 to 12 years old) was measured. The program consisted of 28 audio tapes and printed exercises designed to foster divergent thinking in areas of verbal and figural fluency, flexibility, and originality. A typical session consisted of a 3 to 4 minute segment designed to teach a principle for improving creative thinking, a 10 to 12 minute story about a famous American pioneer, and three or four exercises based on the story content. Analysis of pre- and post-tests on the Torrance Tests of Creative Thinking revealed that Ss in the training group made significantly higher scores than a control group on verbal fluency, verbal flexibility, verbal originality, and the total verbal creativity score.
