Analyzing and mining education big data is the inevitable way for achieving smart education. This project focus on the problem of ‘Mining, analysis and utilization of cross-modal classroom big data’. The study aims at studying the definition and formalization of teaching activity elements, identifying the elements of teaching activities, deeply mining and analyzing the teaching model from the micro- and macro- perspectives, establishing corresponding teaching model bases that describe the teaching process and organization strategies, and proposing a scientific, standardized, effective, and calculable classroom teaching quality evaluation method. It will overcome the difficulties of teaching activity and model representation, multi-task recognition, similarity calculation, and multi-source evaluation fusion decision caused by dynamic relevance of the elements of teaching activities, complexity and diversity of the types, high-dimensional features, sparse values and multisource-based evaluation and decision. It will be verified and demonstrated in the undergraduate teaching of Xi'an Jiaotong University. The research results will effectively support the scientific evaluation and precise supervision of classroom teaching quality in colleges and universities, and promote the formation of a benign operating mechanism of big data-driven teaching quality and drive the scientific management of education. This research proposes to publish above 10 pieces of high quality international journals and conferences papers. |
