Design Conflicts

Product design needs great team efforts from multi-disciplinary participants, even external partners, for collaborative problem solving. Design conflicts within and between functional teams do occur in such a collaborative design process. Detection and resolution of design conflicts through design conformance checking therefore becomes a critical activity in the joint design problem solving. This paper presents the development of a J2EE application prototype to support the STEP-based design conformance checking. A STEP-compliant information model has been specified to represent 3D CAD objects and other design information, while a knowledge representation model been proposed to describe design rules and constraints. The STEP objects and rule objects are managed and processed by the enterprise Java beans of a J2EE application server, which continuously applies the rule objects to the STEP objects and finally draws a conclusion for the design conformance checking. Application scenarios are discussed in the paper to illustrate the effectiveness of both the STEP/rule objects modeling approaches and the prototype system for support of the design compliance checking in distributed environment.

Scrum methodologies that support cross-functional writing teams to develop polished increments of writing instead of lengthy drafts of documents stand to improve productivity and learning within organizations. Scrum methodologies may be deployed in higher education as well as in nonacademic settings to achieve purposeful knowledge transfer across disciplines and across academic/industry borders. Key to scrum is an emphasis on productivity within fixed time frames, with productivity facilitated by learning that emerges in cross-functional teams. Higher education is similarly a domain in which productivity in fixed time frames takes the measure of student learning. Across the disciplines, scrum methodologies show promise for improving the quality of collaborative problem-solving in writing projects in college and at work.

This article presents a practical and collegial model of problem solving that is based upon the literature in supervision and cognitive learning theory. The model and the procedures it generates are applied directly to supervisory interactions in the public school environment. Specific principles of supervision and related recommendations for collaborative problem solving are discussed. Implications for public school supervision are addressed in terms of continued professional growth of both supervisees and supervisors, interdisciplinary team functioning, and renewal and retention of public school personnel.

Abstract. Skilful collaborative problem-solving is becoming increasingly important in various life areas. However, researchers are still seeking ways to assess and foster this skill in individuals. In this study, we developed a computer-assisted assessment for collaborative behavior (COLBAS) following the experiment-based assessment of behavior approach (objective personality tests; Cattell, 1958 ). The instrument captures participants’ collaborative behavior in problem-solving tasks using the MicroDYN approach while participants work collaboratively with a computer-agent. COLBAS can thereby assess problem-solving and collaborative behavior expressed through communication acts. To investigate its validity, we administered COLBAS to 483 German seventh graders along with MicroDYN as a measure of individual problem-solving skills and questions regarding the motivation to collaborate. A latent confirmatory factor analysis suggested a five-dimensional construct with two problem-solving dimensions (knowledge acquisition and knowledge application) and three collaboration dimensions (questioning, asserting, and requesting). The results showed that extending MicroDYN to include collaborative aspects did not considerably change the measurement of problem-solving. Finally, students who were more motivated to collaborate interacted more with the computer-agent but also obtained worse problem-solving results.

Collaborative Construction

AbstractThe important role of student agency in collaborative problem-solving has been acknowledged in previous mathematics education research. However, what remains unknown are the processes of agency in open-ended tasks that draw on real-life contexts and demand argumentation beyond “mathematical”. In this study, we analyse a video recording of two student groups (each consisting of four students) taking part in collaborative problem-solving. We draw on the framework for collaborative construction of mathematical arguments and its interplay with student agency by Mueller et al. (2012). This original framework is supplemented by (i) testing and revising it in the context of open-ended real-life tasks, with (ii) student groups rather than pairs working on the tasks, and by (iii) offering a strengthened methodological pathway for analysing student agency in such a context. Based on our findings, we suggest that the framework suits this new context with some extensions. First, we note that differences in student agency were not only identified in terms of the discourse students drew on, but in how students were able to shift between various discourses, such as between “mathematical” and “non-mathematical” discourses. We identify a novel discourse reflecting student agency, invalidation discourse, which refers to denying other students’ agency by framing their contribution as invalid. Finally, we discuss the need to reframe “mathematical” arguments—and indeed student agency—while the task at hand is open-ended and concerns real-life contexts.
