Exploring Self-Doubt In Community College Computer Science: Evidence From Exploratory Factor Analysis, Trent W. Dawson

Research & Publications

Community college (CC) students make up a growing portion of introductory computing courses, yet little is known about their attitudes going into early programming experiences. This pilot study explored CC students’ initial perceptions of readiness for introductory computing. Exploratory factor analysis revealed two initial dimensions: a higher-perceived-ability factor based on positively framed items and a lower-perceived-ability factor based on negatively framed items. The higher perceived ability factor showed little difference between students with and without programming experience, indicating that early optimism may limit distinctions on positively worded items. In contrast, the factor of lower perceived ability indicated evident differences between …
