Generalized Mass Teaching Behavior Based Analysis Of The Data

With the development of information technology providing the foundation of technology for schools’modernization of education, technology instructional setting in schools reflects the intelligent interaction. During a period of the school teaching, educators take advantage of multi-network, cross-platform and cross-platform terminal information systems to support a new way of learning and blended learning, such as digital learning, collaborative learning, mobile learning, which generally result in the large volume of data, the user data gathering and the data accumulation, has reached a massive extent.The tremendous data, is referred as the vast amounts of data, it may be GB, TB or even PB grade level. Tremendous educational data mining applications become increasingly evident in the field of teaching, as a complex technology of teaching-oriented applications, and are currently still in the preliminary stages of development.From these vast amounts of teaching behavioral data has extracted teaching tacit knowledge, to analyze and grasp the teaching behaviors and mode related to the teachers and students, to put it into practice, to guide and promote new teaching data generation, form benign iteration loop between data and infonmation.Generalization analysis for these teaching behavioral data is utilizing the data reduction approach of teaching behavior to build analytical models and visualization process. Firstly, collect, preprocess data from distributed data sources; secondly, combine with evaluation index to perform data processing and build a concrete analysis of algorithms; then establish a data cube by layering different dimensions of concept, fine-grained division of teaching relationship, abstract multidimensional data model for generalization analysis; finally, build and implement the system platform by using J2EE and various visualization techniques specific charts that show the multidimensional data model; while use database optimization techniques such as creating an index and temporary tables is to improve the retrieval speed.Generalization analysis platform is used for teaching case-control data for horizontal, vertical trend analysis, frequency distribution of classroom behavior and multidimensional data analysis pooled analysis of the number of frequencies. It aims to objectively reflect the statistical facts for teaching by analyzing the results. It is enabling teachers and students to focus on teaching and students process with the way of normal analytical methods. That is to further interactive teaching and learning.
