Furthermore, Kirton's (1976) measure of learning style is harmonious with learning from problem solving. To learn from problem solving, a learner manipulates a principle and interprets the meaning from the manipulation. For effective learning from a problem, Pask (1976) claims the learner must use both holist and serialist cognitive styles. Although Pask and Kirton measure cognitive style differently, they are much the same when considering description and categorization (Cassidy, 2004). Both of these measures of cognitive style are representative of problem solving style. Other types of learning defined by Gange (1965) may be compatible with specific learning styles. For example, the Group Embedded Figures Test (GEFT) (Witkin, Oltman, Raskin & Karp, 1971) measures whether an individual is either field independent or field dependent by the individual's ability to identify embedded figures within geometric shapes. The cognitive processes used to complete the GEFT gives some evidence that field independence and field dependence is a style of concept learning (Gange, 1965). Concept learning is defined as comparing and distinguishing properties of similar items based on knowledge of those items (Gange). However, Witkin (1973) has found that his measure of learning style does have implications for problem solving with regards to the need for structure. Field dependent learners tend to prefer more structure in learning while field independent learners prefer less structure. This corresponds to Kirton's (2003) adaptive individuals who favor structure and innovative individuals who prefer less structure in the effort of problem solving. Learning Style and Learning Process Most psychologists concur that learning occurs through a process or cycle. Research of the brain has found five stages for effective learning (Jensen, 2000), including preparation-background recall of information, acquisition-inputting
