Synthesis: Ratniyom, Boonphadung, Intaraprasit, and Chumkaeo (2026) analyze how pre-service science teachers across achievement levels perceive the distinct roles of human instructors versus ChatGPT in a ChatGPT-enhanced formative assessment of stoichiometry. The human instructor was viewed as an adaptive expert, toggling between Simplifier and Elaborator roles depending on learner achievement; ChatGPT was perceived as a personalized self-regulated-learning tool whose role shifted by achievement — a Patient tutor for low-achievers, a Personal Coach for medium-achievers, and an Intellectual Sparring Partner for high-achievers. The authors propose an Instructor–AI Synergistic Learning Ecosystem model reframing human–AI collaboration as complementary partnership rather than competition.

Design

  • Data: secondary qualitative analysis of interviews with pre-service science teachers, stratified into high-, medium-, and low-achieving groups.
  • Context: ChatGPT-enhanced formative assessment in stoichiometry learning.
  • Setting: 13 pre-service science teachers from a single Thai university (case study).

Findings: distinct instructor vs. GenAI roles

The human instructor was predominantly viewed as an adaptive expert, adept at toggling between two roles based on learners' achievement:

  • Simplifier for lower-achieving students (breaking down complex content)
  • Elaborator for higher-achieving students (extending and deepening understanding)

ChatGPT was perceived as a personalized tool for self-regulated learning, its role shifting with achievement:

  • Patient Tutor for low-achievers — non-judgmental, always-available support
  • Personal Coach for medium-achievers — guided practice and Feedback
  • Intellectual Sparring Partner for high-achievers — challenging and probing ideas

The Instructor–AI Synergistic Learning Ecosystem model

The study's principal contribution is an Achievement-Based Instructor–AI Synergistic Learning Ecosystem model that reframes human–AI collaboration not as competition but as complementary partnership. It positions the instructor as the adaptive expert delivering context-aware feedback while GenAI functions as a personalized SRL tool scaling individualized formative feedback — turning the long-standing challenge of scaling formative assessment in large classes into a pedagogical opportunity. This connects directly to the wiki's Human AI Collaboration concept.

Limitations

The findings are context-specific (13 pre-service teachers, single university, stoichiometry with ChatGPT); perceptions relied on self-reported descriptions rather than full interaction logs; and the model lacks a developmental/longitudinal dimension.
