Curriculum planners and career educators are advised to review the literature on infusion with this question in mind: "Does the integration of career education into the regular secondary classroom make a difference in student learning of subject matter and career information?" The philosophy and objectives of career education infusion were described in four monographs. Hoyt (1976), Preli (1978), and Ristau (1976) stressed the importance of using career education in the classroom to improve students' achievement and motivation. They also found that inservice is necessary to help teachers integrate career education into regular classroom instruction. Suhor (1979) theorized that methods of instruction depend on the district's approach; a district-wide program was instrumental to successful programs. Recent legislation has provided financial support to local school districts for developing career education programs. Congressional hearings supporting the Elementary and Secondary Education Act of 1977 indicated that infusion of career education into the regular classroom resulted in growth in decision-making skills and school-work relationships. Research reports consisted of a variety of methods including surveys, pre- and post-tests, and comparative studies between experimental and control groups using psychometric measures. Three researchers (Bhaerman 1979; Herr 1977; and Wilson 1977) concluded that students exposed to career education infusion had better achievement records than students with no infusion programs. Others, however, noted problems. The following areas need further research: program evaluation, teacher training, and instruction. (KC)
