Subclaims¶

q2 i? Groups composed only of students with high previous activity showed the highest productivity; heterogeneous groups scored slightly worse than these but better than homogeneous-average and homogeneous-low groups. → H. Ulrich Hoppe 2021 q2 i? High-level individual students were more productive in heterogeneous groups, whereas low-level students were more productive in homogeneous groups. → H. Ulrich Hoppe 2021

Evidence¶

H. Ulrich Hoppe, et al. (2021). Using Sequence Analysis to Determine the Well-Functioning of Small Groups in Large Online Courses. International Journal of Artificial Intelligence in Education. https://doi.org/10.1007/s40593-020-00229-9

q2 · i? · associational · r1

Prior observational analysis of group formation strategies in the CmC course (cited as Wichmann et al. 2016), where productivity combined delivered text volume, domain concepts and forum contributions, and formation levels were based on prior forum activity, not pre-knowledge. No effect sizes are printed.

"It was also interesting to see that high-level individual students were more productive in heterogeneous groups, whereas low-level students were more productive in homogeneous groups."

Discussion¶

Related Claims¶

• Between- or within-class homogeneous ability grouping has a small negative effect on low-ability primary students but no effect on other students — reports the opposite
• Homogeneous grouping for reading instruction and heterogeneous grouping for discussion groups each serve distinct purposes — related
• Groups outperform individuals when devising creative solutions to real-world complex problems — related
• Collaborative situations often fail to be productive in practice, so orchestrating collaboration is not simple — a broader claim this one bears on
• The heterogeneous group ranks second on individual achievement gains, behind the high homogeneous group — related
