Automated Personalized Feedback Improves Learning Gains in An Intelligent Tutoring System

Abstract: We investigate how automated, data-driven, personalized feedback in a large-scale intelligent tutoring system (ITS) improves student learning outcomes. We propose a machine learning approach to generate personalized feedback, which takes individual needs of students into account. We utilize state-of-the-art machine learning and natural language processing techniques to provide the students with personalized hints, Wikipedia-based explanations, and mathematical hints. Our model is used in Korbit, 5 a largescale… Show more

“…Our approach contrasts considerably with existing feedback models, such as Rus, Niraula, and Banjade (2015) and Kochmar et al (2020). While these systems can capably guide students towards fixing incorrect ideas, they cannot directly comment on which concepts the students have misunderstood.…”

“…Many ITSs provide feedback guiding students towards the correct solution in an exercise (Ramachandran et al 2018;Rus, Niraula, and Banjade 2015;Nye, Graesser, and Hu 2014;Ventura et al 2018;Al-Nakhal and Abu-Naser 2017;Al-Dahdooh and Abu-Naser 2017;Tamura et al 2015;Guo et al 2016;Shah, Shah, and Kurup 2017;Serban et al 2020;Kochmar et al 2020). However, to our knowledge, none have previously employed a neural discourse-based mechanism for personalized feedback.…”

“…Those are collected in a knowledge base in which TF-IDF and lexicon-based features techniques are applied to provide valuable insights to improve the overall teaching quality and methodology. Kochmar et al (2020) presented automatically generated personalized feedback. The proposal uses the Korbit learning platform from which automated and personalized feedback is generated considering students' individual needs; thus, the feedback is without expert mediation or predefined rules.…”

“…Personalized natural language feedback can be used for such reinforcement, which has been shown to lead to substantial learning gains. 21 Furthermore, as the competent learner is capable of filtering extraneous information and stimuli, increased fidelity and immersion become appropriate at this stage of learning:It is herein recommended that the more immersive end of the XR continuum, where AR, MR, and VR are combined, would be most suitable to support advancing trainees from the advanced beginner to competent stage.…”
