The analysis of the process of collaboration is a central topic in current CSCL research. However, defining process characteristics relevant for collaboration quality and developing instruments capable of assessing these characteristics are no trivial tasks. In the assessment method presented in this paper, nine qualitatively defined dimensions of(More)
The definition of appropriate interaction analysis methods is a major research topic in Computer Supported Collaborative Learning. Analysis methods can be totally or partially supported by computer-based tools that provide for better and more efficient analysis processes. The current research in this field shows that most interaction analysis tools have(More)
Scaffolding learners, i.e. helping learners to attain tasks they could not accomplish without support, entails the notion of fading, i.e. reducing the scaffolding for learners to become more and more self-regulated. Fading implies to tailor support for collaboration, such as collaboration scripts, to the particular needs of the specific collaborators. In(More)
An experiment was designed to study the drawing of inferences from a set of shared and unshared information in dyads collaborating on a specially developed task. Three types of inferences (common, individual, and collaborative) were distinguished based on information sharedness and distribution. In addition, two kinds of instructional support were explored(More)
The Atmospheric Processing Module (APM) is a Mars In-Situ Resource Utilization (ISRU) technology designed to demonstrate conversion of the Martian atmosphere into methane for use as rocket propellant for an ascent vehicle. The Martian atmosphere mainly consists of 95% carbon dioxide (CO2) and residual argon and nitrogen. APM utilized cryocoolers for CO2(More)
One important way in which learners can co-construct new knowledge is by drawing collaborative inferences from distributed information. However, groups rarely use members’ complementary knowledge resources to their best potential. In this experiment, student dyads were trained to apply collaborative inferencing strategies. Training improved students’(More)
