Student-Centered Learning Environment Based on Multimedia Big Data Analysis

The application of current information technology in education, especially multimedia network technology, has brought about major changes the content and methods instruction. It replaced conventional teacher-centered, textbook-centered, classroom-centered teaching environment with a student-centered, technology-based learning that includes rich resources virtual reality. Through interaction between students environment, can acquire knowledge on basis observation, understanding, cognition, so as to grasp essence things. is an effective cognitive tool for explore freely visualize various skills. Therefore, teacher no longer authority imparting, but learner’s guide helper or even senior partner activities. This shift will allow staff focus more design development environments resources. paper proposes new clustering algorithm CURE, which overcomes shortcomings detection rate stability classical suitable solving problem big data analysis. Experiments are carried out some international standard security dataset KDDCUP101, running time 1230 s. results show proposed increased by 30.22% 10.98% compared common algorithm. Compared global K-means algorithm, complexity also greatly enhanced.
