Subclaims¶

q2 i? SC produced highly stable scores across three runs (total-score intra-LLM ICC (2,1) = 0.990, mean within-response SD = 0.098) while its agreement with teacher mean scores remained weaker (ICC (2,1) = 0.537). → Baicheng Lin 2026

Abstract-reported result substantiated in Results Tables 1 and 4: SC total-score intra-LLM ICC (2,1) was 0.990 with mean within-response SD 0.098, yet teacher agreement ICC (2,1) was 0.537. The article states "SC showed weaker agreement with teacher mean scores (ICC (2,1) = 0.537), despite stable scores."

"SC showed weaker agreement with teacher mean scores (ICC (2,1) = 0.537), despite stable scores."

Discussion¶

Related Claims¶

• Under single-pass deployment, Fs+CoT prompting yields the strongest agreement with teacher mean scores for music-analysis essay scoring (r = 0.795, ICC (2,1) = 0.657) — related
• Median aggregation across three runs produces only minor changes in agreement and does not alter the ordering of prompting strategies — related
• Prompting strategies produce distinct directional bias profiles: Fs+CoT under-scores (bias = -1.730), RAG over-scores (bias = 1.787), and SC shows minimal directional bias (bias = -0.083) — related
