The purpose of this quasi-experimental study was to explore how 111 7th graders in the United States developed argumentation skills and science knowledge in a computer-assisted project-based learning environment. The findings indicated that with the computer-assisted program, the quality scores of collaborative argumentation were high and consistent. The difference in argumentation structure and quality of argumentation might explain a difference in science knowledge as well counterargument and rebuttal skills (argumentation) between both conditions.
