Tsinghua University
Ph.D. in Computer Science
Tsinghua University is where Wang Wei pursued the Ph.D. in Computer Science (2010 – 2015).
Tsinghua University is the institution where Wang Wei earned his Ph.D. in Computer Science. He entered the doctoral program in 2010 and defended his thesis in 2015, under the supervision of a professor in the Department of Computer Science and Technology.
Dissertation
Wang's dissertation, Graph-based modeling of student knowledge-state evolution in MOOCs, examined how the historical interaction sequence of a student across MOOC platform exercises could be modeled as a graph of knowledge-concept transitions, and how that graph could be used to predict near-future performance on unseen exercises. The work was grounded in a dataset of approximately three million interaction records from an early Chinese MOOC platform that Tsinghua co-operated at the time. Wang's contribution was the graph formulation and the corresponding training procedure; downstream evaluations were conducted by collaborators at the partner platform.
Publications
During his doctoral studies, Wang published five peer-reviewed papers across the educational-data-mining and learning-analytics venues. The thesis itself was awarded the department's annual outstanding dissertation designation in 2015, and elements of the graph-formulation contribution have since been cited in approximately 90 follow-on papers (Google Scholar, accessed 2026).
Aftermath
Wang has cited the Tsinghua period as both the technical foundation for his subsequent classroom-teaching career and the intellectual root of Codeleaf: the basic question of "what is a student actually learning, and how do we know" was carried forward from the dissertation into the curriculum-design work at the startup, only with a much smaller and more controllable dataset of his own students.
