Since pair programming appeared in the literature as an effective method of teaching computer programming, many systems were developed to cover the application of pair programming over distance. Today's systems serve personal, professional and educational purposes allowing distributed teams to work together on the same programming project. The current research focuses in distributed pair programming systems which are suitable for supporting students in learning computer programming. Systematic review of publicly available systems revealed that there is an absence of effective collaboration support for the students. The main drawbacks of pair programming, such as uneven workload distribution and infrequent role switches, cannot be addressed with available systems. While building an enhanced version of a distributed pair programming system, successful instructional strategies in similar collaborative learning systems were explored, in order to improve students' interactions when applying pair programming over distance. As a result, the new system allows students to practice distributed pair programming in the form of collaboration scripts. This paper presents the features and the underlying concepts of the system, and the results of its first evaluation. The study showed that distributed pair programming attracted positive feedback from students, and that scripted collaboration affected students' engagement in programming, and resulted in an evenly distribution of learning objectives among pairs.
Collaboration scripts provide an integrated framework aimed to foster fruitful collaboration in collaborative learning settings. Since pair programming is also a form of collaborative learning, we explored whether collaboration scripts can improve collaboration in distributed pair programming. For this purpose, we incorporated collaboration scripts in an existing distributed pair programming system. We conducted a pilot study to evaluate the new system by a group of students. Our goal was to examine students' perceptions of computer mediated scripted collaboration and furthermore to evaluate the effectiveness of adaptive role switching in students' participation. The study showed that students' attitude toward distributed pair programming and scripted collaboration was quite positive, however they prefer to distribute tasks by themselves which led half of them not to follow system's suggestions for role distribution.
Pair programming (PP) has become popular in the research and software industry as well as being studied for a number of years in computer science courses with positive findings on student performance and attitudes. Advantages of PP reported in the literature are satisfaction, design quality, code productivity, team building, and communication. More recently, distributed pair programming (DPP), which enables two programmers to work remotely, has also attracted the interest of researchers and instructors. The difference between DPP and PP is that the former allows geographically distributed teams to collaborate and share program code. Such collaboration is, thus, only feasible if an underlying infrastructure supports all necessary interactions. The integrated development environments (IDEs) for DPP should cover the basic requirements for remote software development as well as address common PP problems, such as unequal contributions from each member of a pair, feedback during DPP sessions, and communication problems. This paper presents the findings of a study on student performance and attitudes towards DPP in an object-oriented programming (OOP) course. The factors examined were student performance, in terms of assignment grade, exam grade and implementation time in relation to students’ programming experience, and confidence, as well as student attitudes towards DPP, i.e., the feelgood factor, working alone or with a partner, and the perception of their partner’s technical competence. The results suggest that a students’ performance is associated with their programming experience and confidence in programming but not with how comfortable they feel during DPP sessions. Students evaluate the DPP sessions positively regardless of their confidence on programming or their perception of their partners’ technical competence. Students who consider themselves to have about the same programming competence as their partners tend to be more satisfied with DPP sessions. Overall, students prefer working with a partner regardless of their confidence on programming.
This paper reports students’ perceptions and experiences attending an object-oriented programming course in which they developed software using the Distributed Pair Programming (DPP) technique. Pair programming (PP) is typically performed on one computer, involving two programmers working collaboratively on the same code or algorithm. DPP on the other hand is performed remotely allowing programmers to collaborate from separate locations. PP started in the software industry as a powerful way to train programmers and to improve software quality. Research has shown that PP (and DPP) is also a successful approach to teach programming in academic programming courses. The main focus of PP and DPP research was PP’s effectiveness with respect to student performance and code quality, the investigation of best team formation strategies and studies of students’ attitudes. There are still limited studies concerning relationships between performance, attitudes and other critical factors. We have selected some of the most common factors which can be found in the literature: academic performance, programming experience, student confidence, feelgood factor, partner compatibility and implementation time. The main goal of this study was to investigate correlations between these attributes, while DPP was used as the main programming technique.
