This project was composed of two major research experiments and four subsidiary experiments, designed to test alternative ways of constructing and applying occupational problem-solving materials. In Part I, Difficulty Level of Simulated Vocational Problems in Encouraging Career Exploration, it was found that the difficulty level did significantly interact with initial occupational interest when knowledge of the occupations studied was used as a measure. Part II includes four subsidiary studies: (1) Simulated Work Experience: An Attempt To Encourage Career Exploration, (2) An Optimal Grade Level for Career Exploration?, (3) Vocational Information-Seeking Behavior as Affected by a Problem-Solving Work Kit and Set Establishment, and (4) Simulated Work Experience: How Realistic Should It Be? Results from Part III, Orienting Stimuli in Vocational Problem-Solving as Factors in Promoting Career Information Seeking, indicate that subjects who receive their first choices of vocational stimulation kits reported varied information-seeking activities more than did subjects who were denied their first choices. Also, subjects who receive specific questions comparing occupations achieved higher scores on occupational information tests than did subjects who received general questions. (CH)
