We introduce an AI learning companion designed to enhance STEM education by providing personalized, adaptive learning experiences. The companion dynamically adjusts the difficulty of experimental activities in online STEM labs and delivers targeted feedback based on real-time student performance, ensuring a more efficient learning process. Teachers can use the companion’s authoring tool to create tailored educational scenarios that cater to students at various performance levels. This work emphasizes a student-centered approach, supporting critical thinking and problem-solving skills.
