Decoding Student Dialogue: A Multi-Dimensional Comparison and Bias Analysis of Large Language Models as Annotation Tools
arXiv:2604.04370v1 Announce Type: new Abstract: Educational dialogue is critical for decoding student learning processes, yet manual annotation remains time-consuming. This study evaluates the efficacy of GPT-5.2 and Gemini-3 using three prompting strategies (few-shot, single-agent, and multi-agent reflection) across diverse subjects, educational levels, and four coding dimensions. Results indicate that while multi-agent prompting achieved the highest accuracy, the results did not reach statistical significance. Accuracy proved highly context-dependent, with significantly higher performance in K-12 datasets compared to university-level data, alongside disciplinary variations within the same educational level. Performance peaked in the affective dimension but remained lowest in the cognitiv
Developing Authentic Simulated Learners for Mathematics Teacher Learning: Insights from Three Approaches with Large Language Models
arXiv:2604.04361v1 Announce Type: new Abstract: Large Language Model (LLM) simulations, where LLMs act as students with varying approaches to learning tasks, can support teachers' noticing of student thinking. However, simulations using zero- or few-shot prompting often yield inauthentic knowledge and language, directing teachers to unrealistic reasoning. We evaluate three approaches (Fine-tuning, Multi-agent, and Direct Preference Optimization; DPO) to improve the authenticity and pedagogical utility of simulated students. All approaches improve cognitive and linguistic authenticity, compared with few-shot prompts. Interviews with elementary mathematics pre-service teachers and researchers (\textit{n} = 8) reveal distinct pedagogical affordances. The fine-tuned model produces realistic, b
EcoAssist: Embedding Sustainability into AI-Assisted Frontend Development
arXiv:2604.04332v1 Announce Type: new Abstract: Frontend code, replicated across millions of page views, consumes significant energy and contributes directly to digital emissions. Yet current AI coding assistants, such as GitHub Copilot and Amazon CodeWhisperer, emphasize developer speed and convenience, with energy impact not yet a primary focus. At the same time, existing energy-focused guidelines and metrics have seen limited adoption among practitioners, leaving a gap between research and everyday coding practice. To address this gap, we introduce EcoAssist, an energy-aware assistant integrated into an IDE that analyzes AI-generated frontend code, estimates its energy footprint, and proposes targeted optimizations. We evaluated EcoAssist through benchmarks of 500 websites and a control

[SYCL] Add Q8_0 reorder optimization (~3x tg speedup on Intel Arc) ( #21527 ) Extend the existing reorder optimization to Q8_0. The reorder separates scale factors from weight data for coalesced memory access -- was implemented for Q4_0/Q4_K/Q6_K but Q8_0 was missing. On Arc Pro B70 (Xe2), Q8_0 tg goes from 4.88 to 15.24 t/s (3.1x) on Qwen3.5-27B. BW utilization: 21% -> 66%. The key fix beyond the kernels: Q8_0 was missing from the type check in ggml_backend_sycl_buffer_init_tensor() that allocates the extra struct carrying the reorder flag -- so the optimization was silently skipped. AI (Claude) was used to assist with root cause investigation and writing the kernel code. All code was human-reviewed and tested on real hardware.
