Working solutions to problems are not definitive end points. As a result, code that is technically correct can still be treated as needing revising -- a practice in computer programming known as refactoring. We document how late elementary to middle school students and their undergraduate instructors weigh the possibility of refactoring working…

High-quality talk about issues that raise high-intensity emotions in the public sphere is timely needed. Still, researchers committed to the fostering of high-quality types of school talk generally disregard the role of emotions. We show that this disregard is not accidental and that it conveys a customary reluctance in schools to consider the…

Museum researchers have long acknowledged the importance of dialogue in informal learning, particularly for open-ended exploratory exhibits. Novel interaction techniques like full-body interaction are appealing for these exploratory exhibits, but designers have not had a metric for determining how their designs are supporting productive learning…

The use and effects of a CSCL-tool are not always predictable from the properties of the tool alone, but depend on how that tool is appropriated. This paper presents the findings from a case study about the appropriation of a graphical shared workspace. When students are presented with a new tool they may encounter competing constraints and…

Although protocol analysis can be an important tool for researchers to investigate the process of collaboration and communication, the use of this method of analysis can be time consuming. Hence, an automatic coding procedure for coding dialogue acts was developed. This procedure helps to determine the communicative function of messages in online…
