Conference PaperMediating Students’ Scientific Argumentation to Support Model RevisionZhou, J. Hmelo-Silver; C. E.; Danish, J.; Ryan, Z.; Cruz Gonzalez, C.; Duncan, R. G.; Chinn, C. A.; Murphy D.A. Weinberger; W. Chen; D.Hernández-Leo; D., B. ChenScientific argumentation and modeling are both core practices in learning and doing science. However, they are challenging for students. Although there is considerable literature about scientific argumentation or modeling practice in K-12 science, there are limited studies on how engaging students in modeling and scientific argumentation might be mutually supportive. This study aims to explore how 5th graders can be supported by our designed mediators as they engage in argumentation and modeling, in particular, model revision. We implemented a virtual afterschool science club to examine how our modeling tool – MEME (Model and Evidence Mapping Environment), provided evidence, peer comments, and other mediators influenced students in learning about aquatic ecosystems through developing a model. While both groups that we examined constructed strong arguments and developed good models, we show how the mediators played different roles in helping them be successful.2022-07-0110336588Computersupported collaborative learning107-1141573-4552https://doi.org/1761019National Science Foundation
