Low retention rates in third-level computing courses, despite continuing research into new and improved computer teaching methods, present a worrying concern. For some computing students learning programming is intimidating, giving rise to lack of confidence and anxiety. The noncognitive domain of anxiety with regard to learning computer programming is investigated in this paper and programming anxiety, a constituent component of computer anxiety, is defined. The paper describes a longitudinal research study that has been conducted, which investigates the variance of anxiety amongst undergraduate computing students, with specific emphasis upon their learning programming during their first year in higher education.
