From Problem-Solving to Teaching Problem-Solving: Aligning LLMs with Pedagogy using Reinforcement Learning (2025.emnlp-main)
Copied to clipboard
| Challenge: | Large language models (LLMs) are often optimized for direct question-answering, but their effectiveness is often undermined by strategically withholding answers. |
| Approach: | They propose an online reinforcement learning-based alignment framework that can quickly adapt LLMs into effective tutors using simulated student-tutor interactions. |
| Outcome: | The proposed model outperforms proprietary models like LearnLM and can be used to enhance interpretability and pedagogical quality. |
MathTutorBench: A Benchmark for Measuring Open-ended Pedagogical Capabilities of LLM Tutors (2025.emnlp-main)
Copied to clipboard
| Challenge: | Evaluating the pedagogical capabilities of AI-based tutoring models is critical for guided progress in the field. |
| Approach: | They propose an open-source benchmark for holistic tutoring model evaluation. |
| Outcome: | The proposed model can discriminate between expert and novice teachers with high accuracy. |
q2d: Turning Questions into Dialogs to Teach Models How to Search (2023.emnlp-main)
Copied to clipboard
| Challenge: | Recent dialog generation models use external search APIs to generate grounded responses. |
| Approach: | They propose an automatic data generation pipeline that generates dialogs from questions . they use a large language model to create conversational versions of question answering datasets . |
| Outcome: | The proposed method improves query generation models on a QReCC dataset. |

| Challenge: | Apertus is a fully open suite of large language models (LLMs) designed to address responsibility shortcomings in today’s open model ecosystem, namely data responsibility and global representation. |
| Approach: | They propose to release a fully open suite of large language models (LLMs) that address data responsibility and global representation shortcomings in today’s open model ecosystem. |
| Outcome: | The proposed model is pretrained on openly available data and suppresses verbatim recall of data while retaining task performance. |
