The mediating effect of task presentation on collaboration and children's acquisition of scientific reasoning

There has been considerable research concerning peer interaction and the acquisition of children's scientific reasoning. This study investigated differences in collaborative activity between pairs of children working around a computer with pairs of children working with physical apparatus and related any differences to the development of children's scientific reasoning. Children aged between 9 and 10 years old (48 boys and 48 girls) were placed into either same ability or mixed ability pairs according to their individual, pre-test performance on a scientific reasoning task. These pairs then worked on either a computer version or a physical version of Inhelder and Piaget's (1958) chemical combination task. Type of presentation was found to mediate the nature and type of collaborative activity. The mixed-ability pairs working around the computer talked proportionally more about the task and management of the task; had proportionally more transactive discussions and used the record more productively than children working with the physical apparatus. Type of presentation was also found to mediated children's learning. Children in same ability pairs who worked with the physical apparatus improved significantly more than same ability pairs who worked around the computer. These findings were partially predicted from a socio-cultural theory and show the importance of tools for mediating collaborative activity and collaborative learning

Fostering multidisciplinary learning through computer-supported collaboration script: The role of a transactive memory script

For solving many of today's complex problems, professionals need to collaborate in multidisciplinary teams. Facilitation of knowledge awareness and coordination among group members, that is through a Transactive Memory System (TMS), is vital in multidisciplinary collaborative settings. Online platforms such as ICT tools or Computer-supported Collaborative Learning (CSCL) have the potential to facilitate multidisciplinary learning. This study investigates the extent to which establishment of various dimensions of TMS (specialization, coordination, credibility) is facilitated using a computer-supported collaboration script, i.e. a transactive memory script. In addition, we examine the effects of this script on individual learning satisfaction, experience, and performance. A pre-test, post-test design was used with 56 learners who were divided into pairs based on disciplinary background and randomly divided into treatment condition or control group. They were asked to analyse, discuss, and solve an authentic problem case related to their domains. Based on the findings, we conclude that a transactive memory script in the form of prompts facilitates construction of a TMS and also improves learners' satisfaction with learning experience, and performance. We provide explanations and implications for these results

Facilitating Learning in Multidisciplinary Groups with Transactive CSCL Scripts

Knowledge sharing and transfer are essential for learning in groups, especially when group members have different disciplinary expertise and collaborate online. Computer-Supported Collaborative Learning (CSCL) environments have been designed to facilitate transactive knowledge sharing and transfer in collaborative problem-solving settings. This study investigates how knowledge sharing and transfer can be facilitated using CSCL scripts supporting transactive memory and discussion in a multidisciplinary problem-solving setting. We also examine the effects of these CSCL scripts on the quality of both joint and individual problem-solution plans. In a laboratory experiment, 120 university students were randomly divided into pairs based only on their disciplinary backgrounds (each pair had one partner with a background in water management and one partner with a background in international development studies). These dyads were then randomly assigned to one of four conditions: transactive memory script, transactive discussion script, both scripts, or no scripts (control). Learning partners were asked to analyze, discuss, and solve an authentic problem that required knowledge of both their domains, i.e., applying the concept of community-based social marketing in fostering sustainable agricultural water management. The results showed interaction effects for the transactive memory and discussion scripts on transactive knowledge sharing and transfer. Furthermore, transactive memory and discussion scripts individually, but not in combination, led to better quality demonstrated in both joint and individual problem solutions. We discuss how these results advance the research investigating the value of using scripts delivered in CSCL systems for supporting knowledge sharing and transfer

Perceptions and experiences of, and outcomes for, university students in culturally diversified dyads in a computer-supported collaborative learning environment

The introduction of computer-supported collaborative learning (CSCL), specifically into intercultural learning environments, mirrors the largely internet-based and intercultural workplace of many professionals. This paper utilized a mixed methods approach to examine differences between students’ perceptions of collaborative learning, their reported learning experiences, and learning outcomes when they collaborated in a CSCL environment working with a culturally similar or dissimilar partner. Culturally diverse student dyads worked together to perform an online learning task in the domain of life sciences. Our sample of 120 BSc and MSc students was comprised of 56 Dutch and 64 international students, representing 26 countries. The results showed that students from an individualist cultural background had a more negative perception of collaborative learning than did students with a collectivist background, regardless of group composition. For women, working in a culturally similar dyad consisting of students from an individualist cultural background resulted in a more negative perception of collaborative learning than did working in this type of group for men or women working in a culturally similar dyad consisting of students from a collectivist cultural background. Students from an individualist cultural background achieved better learning outcomes than did students with a collectivist background, regardless of group composition. These findings suggest that cultural background adds an important dimension to collaborative learning, which requires students to manage collaboration that is not only virtual but also intercultural
