Say What? Automatic Modeling of Collaborative Problem Solving Skills from Student Speech in the WildPugh, Samuel; Subburaj, Shree Krishna; Rao, Arjun Ramesh; Stewart, Angela E; Andrews-Todd, Jessica; D’Mello, Sidney K (, Proceedings of The 14th International Conference on Educational Data Mining)We investigated the feasibility of using automatic speech recognition (ASR) and natural language processing (NLP) to classify collaborative problem solving (CPS) skills from recorded speech in noisy environments. We analyzed data from 44 dyads of middle and high school students who used videoconferencing to collaboratively solve physics and math problems (35 and 9 dyads in school and lab environments, respectively). Trained coders identified seven cognitive and social CPS skills (e.g., sharing information) in 8,660 utterances. We used a state-of-theart deep transfer learning approach for NLP, Bidirectional Encoder Representations from Transformers (BERT), with a special input representation enabling the model to analyze adjacent utterances for contextual cues. We achieved a microaverage AUROC score (across seven CPS skills) of .80 using ASR transcripts, compared to .91 for human transcripts, indicating a decrease in performance attributable to ASR error. We found that the noisy school setting introduced additional ASR error, which reduced model performance (micro-average AUROC of .78) compared to the lab (AUROC = .83). We discuss implications for real-time CPS assessment and support in schools.more » « less

Andrews-Todd, Jessica; Forsyth, Carol M. (, Computers in Human Behavior)New challenges in today’s world have contributed to increased attention toward evaluating individuals’ collaborative problem solving (CPS) skills. One difficulty with this work is identifying evidence of individuals’ CPS capabilities, particularly when interacting in digital spaces. Often human-driven approaches are used but are limited in scale. Machine-driven approaches can save time and money, but their reliability relative to human approaches can be a challenge. In the current study, we compare CPS skill profiles derived from human and semiautomated annotation methods across two tasks. Results showed that the same clusters emerged for both tasks and annotation methods, with the annotation methods showing agreement on labeling most students according to the same profile membership. Additionally, validation of cluster results using external survey measures yielded similar results across annotation methods.more » « less
