Growing concern for an improvement in the formal learning situations experienced by adults is reflected in much of the literature currently available. Evidence from studies of adult learning suggests that (i) adults are generally well able to accept a significant degree of responsibility for the management of their own learning, and (ii) that an adult's learning is enhanced if the learning situations are matched to the preferences and strengths of the learner. In this study a design for adult instruction, which takes these factors into account, is developed. The Educational Cognitive Styles of 47 adult learners are mapped using a self-report inventory. The profiles thus obtained are used in the development of instructional techniques for the learners who are enrolled in a first-year, TAFE, para-professional course. Comparison of this experimental group with a control group indicates that the attrition rate is reduced, learners have more positive feelings toward their course of study, and performance on a content achievement test is, arguably, improved.
