Hochstein, LorinNakamura, TaigaShull, ForrestZazworka, NicoVoelp, MartinZelkowitz, Marvin V.Basili, Victor R.The classroom is a valuable resource for conducting software engineering experiments. However, coordinating a family of experiments in classroom environments presents a number of challenges to researchers. This paper describes an environment that simplifies the process of collecting, managing and sanitizing data from classroom experiments, while minimizing disruption to natural subject behavior. We have successfully used this environment to study the impact of parallel programming languages on programmer productivity at multiple universities across the United States.en-USsoftware engineering experimentscollecting datamanaging datasanitizing dataparallel programming languagesuniversitiesTechnical Report
