Temporal Analysis of Elementary Teachers’ Affective Change in Indischool: Focusing on the Educational Issues Board(2022.9.–2025.6.)

This study conceptualizes online teacher discourse as ‘affective practice’ to trace the collective affect trajectory surrounding the 2023 Seoi Elementary incident. Analyzing 268,903 ‘Indischool’ posts (Sep 2022–Jun 2025) via Large Language Models and Bayesian Change Point detection, we identified a three-phase transformation: ‘Accumulation(chronic discontent) – Explosion (ambivalent solidarity) – Submergence(structural powerlessness).’ Results show teacher affect reached a critical threshold two weeks pre-incident, acting as a catalyst rather than a root cause. Subsequently, rage and solidarity surged simultaneously. Post-September 4th protests, indicators declined below pre-incident levels, marking a ‘submergence’ into a pervasive atmosphere of resignation. These results frame the teaching crisis as a collective affective phenomenon rooted in institutional contradictions, requiring structural reform rather than individual adaptation.
