Wambsganss, T., Benke, I., Maedche, A., Koedinger, K., & Käser, T. (2025). Evaluating the Impact of Learner Control and Interactivity in Conversational Tutoring Systems for Persuasive Writing. International Journal of Artificial Intelligence in Education. https://doi.org/10.1007/s40593-024-00409-x

q3 · i? · causal · r?

Assessment-quality gains: TG1 mean 0.052 (SD = 0.605) vs CG mean -0.052 (SD = 0.704); "The results show no significant difference between TG1 and CG".

"Students using WritingTutor rated their perceived learner autonomy with a mean value of 5.521 (SD = 0.946) and showed an improvement in learning outcomes of 0.052 between the pre- and post-tests (SD = 0.605). Students in the control group rated their perceived learner autonomy with a mean of 5.22 (SD = 1.09); however, they did not show an improvement in learning outcomes between the pre- and post- tests (mean = -0.052, SD = 0.704). The results show no significant difference between TG1 and CG"
