Designing Safe and Relevant Generative Chats for Math Learning in Intelligent Tutoring Systems
Designing Safe and Relevant Generative Chats for Math Learning in Intelligent Tutoring Systems Abstract Large language models (LLMs) are flexible, personalizable, and available, which makes their use within Intelligent Tutoring Systems (ITSs) appealing. However, their flexibility creates risks: inaccuracies, harmful
Analyzing Student Attention and Acceptance of Conversational AI for Math Learning: Insights from a Randomized Controlled Trial
Analyzing Student Attention and Acceptance of Conversational AI for Math Learning: Insights from a Randomized Controlled Trial Abstract The significance of nurturing a deep conceptual understanding in math learning cannot be overstated. Grounded in the pedagogical strategies of induction, concretization,
Students’ perceived roles, opportunities, and challenges of a generative AI-powered teachable agent: a case of middle school math class
Students’ Perceived Roles, Opportunities, and Challenges of a Generative AI-powered Teachable Agent: A Case of Middle School Math Class Abstract Ongoing advancements in Generative AI (GenAI) have boosted the potential of applying long-standing “learning-by-teaching” practices in the form of a
Math Multiple Choice Question Generation via Human-Large Language Model Collaboration
Math Multiple Choice Question Generation via Human-Large Language Model Collaboration Abstract Multiple choice questions (MCQs) are a popular method for evaluating students’ knowledge due to their efficiency in administration and grading. Crafting high-quality math MCQs is a labor-intensive process that
Automated Feedback for Student Math Responses Based on Multi-Modality and Fine-Tuning
Automated Feedback for Student Math Responses Based on Multi-Modality and Fine-Tuning Abstract Open-ended mathematical problems are a commonly used method for assessing students’ abilities by teachers. In previous automated assessments, natural language processing focusing on students’ textual answers has been
