Pedagogical & Methodological Comparison of AI-in-Education Studies

This table compares five contemporary education-technology studies that span LLM alignment, LLM adoption reviews, K–12 AI interventions, early-childhood digital math, and peer-based prompt literacy. Each row is a paper and columns are concise attributes (year, type, method, sample, data, impact, evidence, innovation, limitation, recommendation). Use this table to quickly locate methodological choices, measured outcomes (e.g., digital literacy, alignment, engagement), and recommended next steps (e.g., prompt tuning, controlled trials, teacher professional development) across small-scale experiments, large reviews, and qualitative studies.
