Pair Programming in Introductory Programming Labs

ABSTRACT: This project looks at the practice of pair programming as a vehicle for improving the learning environment in introductory computer science labs, a nearly universal course for all engineering students. Pair programming is a practice in which two programmers work collaboratively at one computer, on the same design, algorithm, or code. Prior research indicates that pair programmers produce higher quality code in essentially half the time taken by solo programmers. A multiyear project is currently underway at North Carolina State University, looking at the efficacy of pair programming in an introductory Computer Science (CS1) course. Results indicate that student pair programmers are more self-sufficient in lab and are more likely to complete the class with a grade of C or better. The effect of pair programming on specific graded exams and projects are less clear. Demographic data, prior achievement scores, and current course scores were brought together with interview data, attitude surveys, and in-lab observations to guide the evaluation. As part of the in-lab data collection, novel techniques are being developed to better understand pair dynamics and student/instructor interactions. Collectively, these evaluative methods have guided the iterative implementation of paired programming instructional methods. Current challenges being addressed include lab instructor training, student/instructor concerns over equity in effort on assignments, pair dynamics in lab, and collaborative logistics of pair programming outside of lab.
