PAPER CITATION
Sampson, V., & Clark, D. (2009). The impact of collaboration on the outcomes of scientific argumentation. Science Education, 93(3), 448–484.
In this study, researchers investigated the commonly held view that collaboration improves scientific argumentation. The study tested the perspective that in collaborative investigations individuals build off each others' ideas, taking advantage of different cognitive and monitoring resources in the group, in order to develop more compelling and accurate scientific arguments than they would have if they had been working alone. The study results showed a mix of outcomes for the students.
The authors investigated three questions: (1) Do groups of students craft higher quality arguments than students working alone? (2) To what extent do students who work in groups adopt the arguments generated by their group? (3) Do students who work in groups generate better arguments on mastery and transfer questions than individuals who are working alone?
To answer these questions, the authors set up 168 high-school chemistry students in an experimental design so that they worked in collaborative or individual conditions. The students were introduced to a framework intended to help them understand and evaluate a high-quality argument, which included explanation, evidence, and reasoning. The students worked on a task that required them to produce an argument articulating and justifying an explanation for a discrepant event. They then completed mastery and transfer problems individually.
Although they had worked in small groups in their classes to complete laboratory exercises, the students did not have prior experience with the collaboration and argumentation expected of them here. This was a purposeful strategy by the authors to see what students would do and learn when first asked to engage in a foreign practice in their classroom.
Results for each of the research questions and implications for practice are given below:
- Research question 1 – Student collaboration did not improve the quality of the argument they produced. This finding was contrary to other past studies, but suggests that when students have little experience with collaboration, educators will need to do more than design a meaningful task. Teachers and educators may need to teach students how to introduce ideas into a discussion, to value intellectual rigor, give and get constructive criticism, and to challenge ideas.
- Research question 2 – Individual students adopted at least some of their group’s argument, but a significant proportion later developed better quality arguments individually than they had with the group. The authors believe that the interactions within some groups constrained, rather than enhanced, the collaborative process. As noted above, they believe that targeted instruction on how to collaborate may help improve outcomes.
- Research question 3 – When asked to individually solve mastery and transfer tasks, the students who had been in the collaborative groups did better. The opportunity to bounce ideas off each other, to listen to others' viewpoints, and to think about the problem or what counts as good arguments seems to have been more important than coming to agree within the group.
