Artificial Intelligence (AI) is no longer a distant futuristic concept. It is rapidly changing many aspects of our lives, including education. From kindergarten classrooms to university lecture halls, AI is reshaping how teachers teach and how they prepare to use advanced technology in their work.
A recent comprehensive study by researchers from The Education University of Hong Kong reviewed nearly a decade’s worth of research, from 2015 through mid-2024, to understand AI’s growing role in education. The findings reveal both exciting opportunities and real challenges in how AI technologies are integrated into teaching and teacher professional development.
Steady Growth in AI Research for Education
Research focusing on AI in teaching and teacher professional development has grown significantly in recent years. While AI use in education started gaining traction in 2019, there was a notable surge in publications starting in 2022. This jump coincides with the rise of generative AI technologies such as ChatGPT, which have opened new doors for intelligent tutoring, personalized learning, and automated feedback.
What AI Technologies Are Being Used?
The study categorized AI technologies in education into five main types:
- Conversational AI and related technologies: Chatbots like ChatGPT that help with student engagement, feedback, and content generation.
- AI-driven learning and assessment systems: Platforms that analyze student performance and automate assessments.
- Immersive technologies: Augmented reality (AR), virtual reality (VR), and educational robots.
- Visual and auditory computing: Speech recognition and emotion analysis tools.
- Teaching and learning analytics: Tools that help teachers assess and tailor educational experiences through data analysis.
Among these, conversational AI—especially chatbots—have become the most frequently used technologies, supporting teachers and students in diverse disciplines and settings.
Teacher Perspectives: AI’s Role in the Classroom
Of the 95 studies examined, 65% addressed how AI is applied directly in teaching, across disciplines like English, mathematics, computer science, science, and languages. Higher education saw the most focus, followed by secondary and primary education, with growing attention on special education.
AI tools help teachers deliver personalized instruction, automate routine tasks such as grading, and provide real-time feedback to students. For example, chatbots assist language learners in practicing vocabulary and pronunciation, while immersive AR/VR tools enhance creativity in art and improve language proficiency.
However, integrating these diverse technologies demands teachers acquire new technical skills and adapt pedagogy, which can be overwhelming without adequate training.
The Gap: Professional Development for Teachers
While AI in teaching has attracted much scrutiny, the study found that only 35% of research focused on how teachers develop professionally to use AI effectively. This gap means many teachers lack structured support and training to keep pace with AI innovations.
Key elements shaping AI-related professional development include knowledge acquisition about AI, applications in the classroom, ethical considerations, and building confidence and self-efficacy. Programs are increasingly designed around these principles but need to evolve from short-term workshops to continuous, immersive learning experiences.
Encouraging Progress: AI Supporting Teacher Training
Multiple studies showed promise in using AI tools to enhance teacher training. Chatbots can simulate classroom scenarios, provide personalized coaching, and help teachers design lessons using AI-generated content. For example, ChatGPT-assisted training was found to boost pre-service teachers’ confidence and higher-order thinking skills more effectively than traditional methods.
AI-enabled platforms also help teachers analyze their teaching styles and student interactions via real-time data, providing valuable feedback for professional growth.

Challenges and Future Directions
The study underscored several challenges:
- Technological Skill Demands: Teachers require ongoing training to handle diverse AI tools effectively.
- Ethical Concerns: Privacy, bias, and accountability issues arise with AI use in classrooms.
- Mismatch in Training: Teachers often find that existing professional development does not meet practical classroom needs.
- Unequal Access: High costs of certain technologies may deepen educational inequalities.
To address these, experts recommend:
- Expanding research on AI in teacher professional development.
- Developing comprehensive, continuous AI literacy training for educators.
- Creating evaluation frameworks to assess the effectiveness of AI professional development.
- Addressing ethical and technological challenges proactively.
