The importance of learning styles to student retention and career decision guidance is considered. Learning style is the way people process information and solve problems. Research on right and left brain processing, which indicates that the left hemisphere controls thoughts that are predominately rational and the right hemisphere controls thoughts that are predominately intuitive, has implications for learning styles. Findings indicate both kinds of processing are equally valuable; yet, education concentrates heavily on the left brain while ignoring the development of the right. Since students differ in learning style, certain educational approaches are more effective than others for each individual. Some researchers have theorized that learning style and mapping can be used to help determine the style of work for which one is best suited. Retention in school may also be strengthened when students are able to find the right major based on knowledge and learning style. Measures that are designed to identify learning styles are described as follows: Group Embedded Figures Test (Witkin, Oltman, Raskin, and Karp), Learning Style Inventory (Kolb), Learning Style Inventory (Dunn, Dunn, and Price), Prescription for Learning (Dixon), Learning Style Inventory (Renzulli and Smith), Cognitive Style Interest Inventory (Hill), Inventory of Learning Process (Schmeck), Learning Style Inventory (Silver and Hanson), and Transaction Ability Inventory (Gregoric). In addition, preliminary findings of research studying the relationship between learning style, grade point average, American College Testing scores, attrition, and choice of major are briefly reviewed.
