In computer science, an expected outcome of a student's education is programming skill. This working group investigated the programming competency students have as they complete their first one or two courses in computer science. In order to explore options for assessing students, the working group developed a trial assessment of whether students can program. The underlying goal of this work was to initiate dialog in the Computer Science community on how to develop these types of assessments. Several universities participated in our trial assessment and the disappointing results suggest that many students do not know how to program at the conclusion of their introductory courses. For a combined sample of 216 students from four universities, the average score was 22.89 out of 110 points on the general evaluation criteria developed for this study. From this trial assessment we developed a framework of expectations for first-year courses and suggestions for further work to develop more comprehensive assessments.

Personal response systems (PRS)-also called student response systems (SRS), or more commonly, "clickers"-can be a catalyst for transformation of a learning environment from one of silence to one rich in dialogue and interaction. But how is this transformation achieved? In this paper, we present three case studies of instructors who use PRS in undergraduate science and math classes at a research-intensive institution in the Midwest, USA. All three instructors reported having to make significant adjustments to their teaching over time in order to transform their respective learning environments and fully realize the benefits of PRS. These adjustments included (1) modifying activities to overcome the tension between the students' desire for anonymity and the need for interactivity to enhance learning, and (2) revising PRS questions in response to student behavior. We contend that transformation of the environment with PRS is neither instantaneous nor straightforward. As such, faculty who introduce PRS to their classrooms may benefit from substantial pedagogical and technological support. Finally, we note that the ongoing feedback about student learning in the classroom that PRS provides may act as a powerful catalyst to transform faculty, moving them from teacher-centered conceptions and approaches to teaching to student-centered conceptions and approaches.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
