Evidence¶

Cheng 2026¶

Cheng, N., Liu, H., Xu, X., Zhao, W., Qiao, L., & Zhang, G. (2026). Enhancing Human-Generative Artificial Intelligence Online Collaboration Outcomes: The Pivotal Function of Symbiotic Role Design. The International Review of Research in Open and Distributed Learning, 27(2), 46–66. https://doi.org/10.19173/irrodl.v27i2.9189

q3 · i? · causal · r?

Self-report perception measures collected in the pretest-posttest quasi-experiment with 58 graduate students. The article reports the role design "improved perceived usefulness and ease of use of GAI among learners"; no effect size is printed in the supplied text.

"(c) improved perceived usefulness and ease of use of GAI among learners, although it also led to a moderate increase in collaborative cognitive load"

Cheng 2026 (2)¶

q3 · i? · causal · r?

Perceived collaborative cognitive load was measured as an outcome in the same quasi-experiment. The article states the intervention "led to a moderate increase in collaborative cognitive load"; no effect size is printed in the supplied text.

"(c) improved perceived usefulness and ease of use of GAI among learners, although it also led to a moderate increase in collaborative cognitive load"
