Overview

Large Language Models (LLMs) have emerged as powerful tools in artificial intelligence, capable of understanding and generating human-like text. This means that computers can now engage in natural conversations, answer complex questions, and generate educational content at scale. In educational settings, these models offer unprecedented opportunities for personalized learning, automated content creation, intelligent tutoring, and assessment automation. However, their integration raises significant concerns about academic integrity, data privacy, algorithmic bias, and the pedagogical implications of AI-driven education.

This comprehensive review, based on a systematic analysis of 150 primary studies from 2018-2023, proposes a novel theoretical framework for integrating LLMs into education. Specifically, the framework addresses three interdependent pillars: Personalized Learning Models, Ethical and Pedagogical Balance, and Learning Adaptability Framework. For example, personalized learning models enable adaptive content delivery based on individual student performance and preferences.

Key Finding

LLMs like ChatGPT demonstrate significant potential in education, achieving 96% accuracy on Basic Life Support (BLS) tests and 92.1% on Advanced Cardiovascular Life Support (ACLS) examinations. Because these models can provide accurate information and personalized feedback, they serve as effective supplementary educational tools for both formal learning and self-study scenarios.

Theoretical Framework for LLM Integration

The review proposes a novel theoretical framework built on three interdependent pillars to guide ethical and effective LLM integration in education:

Pillar Description Key Components
Personalized Learning Models Tailored educational content meeting individual student needs through adaptive systems Student data analysis, learning pace adaptation, dynamic feedback loops, performance tracking
Ethical and Pedagogical Balance Strategies addressing AI bias, data privacy, and overreliance while enhancing critical thinking Human-in-the-loop approaches, bias detection, transparency protocols, teacher oversight
Learning Adaptability Framework Flexible AI systems adapting to diverse educational contexts (K-12, higher education, online) Multimodal integration (AR/VR), cross-context scalability, cultural sensitivity
