Do Deep Neural Nets Display Human-like Attention in Short Answer Scoring?

no code implementations NAACL 2022 Zijie Zeng, Xinyu Li, Dragan Gasevic, Guanliang Chen

Deep Learning (DL) techniques have been increasingly adopted for Automatic Text Scoring in education.

Bigger Data or Fairer Data? Augmenting BERT via Active Sampling for Educational Text Classification

1 code implementation COLING 2022 Lele Sha, Yuheng Li, Dragan Gasevic, Guanliang Chen

Pretrained Language Models (PLMs), though popular, have been diagnosed to encode bias against protected groups in the representations they learn, which may harm the prediction fairness of downstream models.

Large Language Models Meet User Interfaces: The Case of Provisioning Feedback

no code implementations17 Apr 2024 Stanislav Pozdniakov, Jonathan Brazil, Solmaz Abdi, Aneesha Bakharia, Shazia Sadiq, Dragan Gasevic, Paul Denny, Hassan Khosravi

Incorporating Generative AI (GenAI) and Large Language Models (LLMs) in education can enhance teaching efficiency and enrich student learning.

Robust Educational Dialogue Act Classifiers with Low-Resource and Imbalanced Datasets

no code implementations15 Apr 2023 Jionghao Lin, Wei Tan, Ngoc Dang Nguyen, David Lang, Lan Du, Wray Buntine, Richard Beare, Guanliang Chen, Dragan Gasevic

We note that many prior studies on classifying educational DAs employ cross entropy (CE) loss to optimize DA classifiers on low-resource data with imbalanced DA distribution.

Does Ability Affect Alignment in Second Language Tutorial Dialogue?

no code implementations WS 2018 Arabella Sinclair, Adam Lopez, C. G. Lucas, Dragan Gasevic

We find that lexical priming in learner-tutor dialogues differs from that in conversational and task-based dialogues, and we find evidence that alignment increases with ability and with word complexity.
