Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Comparing paired models sharing the same base, additional test-time reasoning produced no measurable improvement on expert-rating or learning-gain alignment, and chain-of-thought prompting findings were similar. → Michael Hardy 2026

q2 · i? · causal · r1
Paired comparisons in Sec. 5.2 of reasoning variants against their base models (e.g., DeepSeek-R1 vs DeepSeek-V3.1) on both Kendall's tau alignment axes. The article concludes additional reasoning context alone does not repair the core mismatch.
"we findno measurable improvementon either axis of alignment in Figure 4. Findings comparing the chain-of-thought prompt were similar"

Related Claims¶
- Tutoring quality belongs to the base model and agent harness together rather than either alone, as adapter rankings reorder across tiers — related
- Curricular chain-of-thought prompting improves competency-classification accuracy over zero-shot, with gains concentrated in larger models, while definition-based prompting does not improve performance — reports the opposite
- Chain-of-thought prompting improved LLM multistep reasoning, operationalized via decomposition and interleaved planning approaches — related
- Chain-of-thought prompting yields higher-quality GenAI feedback on argumentative essays than Zero-shot prompting and teacher feedback — related
- Zero-shot prompt type has minimal impact on LLM-human coding concordance — related
- Enforcing an explicit multi-step reasoning structure yields no significant improvement for the two studied models, which already self-organize an effective reasoning structure — related
- Prompting with category information or few-shot examples yields limited improvement in distribution alignment, with zero-shot closest for most models — related
- Chain-of-thought and reasoning prompting significantly improve LLM proportional match with human-authored distractors over direct prompting on both math and science MCQs — related
- GenAI models span multiple agent types, mainly model-based and goal-based, but categorisation is difficult without model specifics — related
- DTR (Deep-Thinking Ratio) does not predict tutoring quality despite predicting math accuracy — related
- Model and prompt choice account for only a small share of misalignment error, which concentrates in transcript-conditioned higher-order interactions — related
- The author reports that prompt phrasing and the specific foundational model had secondary impact on final material quality compared with the structure of the workflow itself. — related
