Transforming EdTech with Conversational AI Teaching Assistants

Education technology has come a long way in the past 5 years, blending innovation with accessibility. The ubiquity of virtual classrooms, online courses, and digital tools have significantly expanded educational opportunities. However, as EdTech adoption increases, it has exposed several gaps in the online learning experience, including low student engagement and course completion rates, limited personalization, and practical constraints that prevent instructors from effectively addressing individual student needs.

Conversational AI is poised to address these challenges and improve the online education experience. By leveraging advanced large language models (LLMs), conversational AI can facilitate realistic, interactive learning experiences through virtual teaching assistants (TAs).

AI Teaching Assistants: Always On, Always Engaged

AI-powered teaching assistants can transform traditional EdTech solutions by providing intelligent, personalized interactions. For example, AI teaching assistants can instantly adapt to student needs, enabling efficient, personalized, one-on-one instruction with the following capabilities:

• Real-Time Interaction: Conversational AI simulates authentic dialogue, providing continuous practice and immediate feedback, which is especially valuable in language learning.
• ‍Continuous Instructor Presence: AI TAs act as a constant support system, helping students remain engaged and motivated even beyond class hours. ‍
• Bridging Learning Gaps: AI-driven interaction enables targeted follow-up and reinforcement of key lesson concepts between sessions, ensuring that students stay on track. ‍
• Personalized Learning Experiences: AI can tailor learning paths based on student performance, quiz results, and historical engagement, creating a unique and optimized learning experience for each student.

Tailoring AI Teaching Assistants to Your Curriculum

To get started with AI-powered TAs, EdTech providers can integrate their existing educational content with a powerful LLM using Retrieval Augmented Generation (RAG), enabling scalable and personalized student support.

RAG, is an AI framework that enhances the capabilities of large language models (LLMs) by incorporating information retrieval. It works by retrieving relevant information from specific sources like knowledge bases or course content and using this retrieved information to tailor the LLM's generation process, leading to relevant responses for specific use cases, like education on a specific topic or language.  

This integration process typically involves the following steps:

1. Ingest Course Content: Institutions upload their curricular materials, creating a foundational knowledge base for the LMM that will be used to power the AI teaching assistant. ‍
2. Create Virtual TAs: Connect the customized LLM to a service for conversational AI that enables real-time voice interaction.
3. ‍Integrate AI TA Into Learning Platform: Integrate your voice AI TA into your application or learning platform.
4. ‍Enable AI Instruction: Allow students to join learning sessions with the AI-powered TA to reinforce lesson material, ask questions, facilitate verbal quizzes or language practice,  and more.  

Leading the Way: Real-World AI Learning Example

Several EdTech companies are already using conversational AI to improve learning outcomes. Companies like Duolingo and Praktika.ai effectively use conversational AI to revolutionize language learning with personalized language learning and adaptive practice with an AI avatar.  

For example, Duolingo’s AI-powered video calls offer live conversation practice with an AI avatar named Lily. The feature is designed to simulate natural dialogue and provides a stress-free, interactive practice environment for speaking skills. The AI adapts to the learner's skill level, making it accessible for beginners and helpful for more advanced students as well.

The avatar features expressive animations to react to what the user is saying, provides transcripts for review, and occasionally calls the learner to initiate practice. This AI assisted approach makes language practice engaging and sustainable, significantly improving student motivation and retention.

Agora's Conversational AI: Advancing EdTech Innovation

As illustrated by platforms like Duolingo and Praktika.ai, conversational AI holds immense potential for EdTech innovation. However, educational institutions aiming to leverage these capabilities require technology that enables natural, engaging interactions at scale. Agora’s Conversational AI Engine makes this possible with ultra-low latency voice interaction, powered by a global real-time network.

Key features of Agora's Conversational AI Engine include:
