Stress. The perception of a stimulus in the form of an event or condition and requires an individual to adjust from normal life. Stressors can be positive or negative depending on the individual's reaction to the experience (Gadzella, 1994; Romano, 1992). Stress was operationalized with use of the Student-life Stress Inventory (SSI) with constructs of frustrations, conflicts, pressures, changes and self-imposed stress. Summary In summary, learning styles theory has become popular as pragmatic educators can easily see its existence in the classroom. However, many learning style instruments have proven to be unreliable and invalid. There is little empirical evidence that dissimilar learning styles contribute to understanding stress, motivation, and engagement; these are common variables found in the undergraduate classroom. Kirton's theory of A-I provides a framework to distinguish cognitive style from cognitive level to help understand the influences of the aforementioned variables. As faculty members become more accountable for student engagement and look for instructional methods to promote learning, evidence is needed to determine the importance of learning styles in student engagement. Kirton's definition of cognitive style and psychometrically sound instrument to measure cognitive style may be of particular use.
