 the performance of each lecturer on a daily basis. We typically have multiple instructors for each course, with each instructor focusing on separate topic areas. We believe this allows our instructors to focus, and offer more in-depth teaching, on their specific areas of expertise within a subject.
Classroom-based learning
Our learning centers function as classrooms for delivering lectures. As of December 31, 2024, we directly managed a total of 218 learning centers in 53 cities across mainland China for our STEM education business. Learning centers for our STEM education business vary in terms of size, ranging between approximately 300 and 700 square meters. The number of students vary according to different courses, with typically around 6 to 8 students in small classrooms and 12 to 15 students in large classrooms.
In 2024, STEM education learning centers are distributed in 53 cities, and the student enrollments of STEM education were approximately 191,200.
Our students are generally required to physically attend classes at our learning centers. We believe physical attendance is important as it creates a disciplined and focused learning environment for students to effectively master the course content. Requiring students to physically attend classes also facilitates the delivery of personalized and systematic tutoring. Our classroom technology infrastructure allows students to interact with instructors online to receive help on course materials and to use online modules to take notes and conduct practice exercises.
Online learning modules
Our live distance instruction and classroom-based learning are supplemented by our proprietary online learning modules featured on our TTS platform. TTS has the following five core functions:

●   Course content. TTS contains lecture slides, key lecture video recordings, case studies, practice exercises and supplemental reading materials. In addition to recordings of past lectures, TTS also features exclusive online videos on key course materials. To foster effective learning of our course lecture materials, especially theoretical knowledge points, TTS features case studies and practice exercises. TTS contains supplemental reading materials on key areas of study. TTS also allows students to download various STEM materials and study notes.

●   Self-assessment examinations. TTS features daily and weekly interactive assessments to measure learning outcomes. TTS provides students with progress tests related to the course contents and asynchronous review videos that synchronize the course curricula and study pace, serving to help students review, memorize and better apply the key points learnt at the class. Teachers can leverage the TTS platform to monitor the review progress and learning results of individual students and answer their questions on a timely basis. Students and/or their
