Research On Teaching Big Data Collection Model For Learner's Knowledge Construction Process

Under the traditional education system,most of the students' data are results files such as final exam scores.Each student's data amount is only a few Kb,and the data tracking and recording of the learning process is almost zero,and interpretable teaching data cannot be formed.It is impossible to analyze the student's learning process and knowledge construction process,and it is difficult to teach students according to their aptitude.The drawbacks of exam-oriented education are further highlighted in the era of big data.At the same time,with the widespread use of smart phones and the current status of wireless campus network coverage,more and more students are bringing mobile terminals into classroom teaching to provide conditions for the collection of teaching big data.This study first analyzes the current domestic and international teaching big data and data acquisition status,summarizes the current shortage of teaching data collection,and follows and analyzes the learning object metadata in CELTS(Network Education Technology Standard System),learning Model,learning management,put forward the construction principles of data collection model,learn from user behavior analysis,ie URL: access-activity-transaction,and the multi-dimensional and multi-level thinking of network learning behavior system,summed up the learning process.The three aspects: behavioral subject,behavioral environment,and behavioral flow.Based on these,a “page access-interactive operation-learning activity” model was constructed,and according to this model,the teaching data collection index was formulated for the data acquisition app.The design and development provide the basis.Secondly,combined with constructivism theory and knowledge construction theory,the user needs and feasibility analysis,in order to not only meet the learner's basic learning function,but also to achieve the data acquisition function,determine the system interface color and layout,design Five modules are closely integrated with learning theory: curriculum,notes,tasks,inquiry learning,and communication.Through the two roles of teachers and students,the function and use of each module are described separately.Finally,according to the constructed model and the interface and module design,the author used the page creation tool Dreamweaver cc,the development technology HTML5 and JQuery,the database MongoDB,the mobile terminal to use phoneGap to develop and implement the system,and demonstrated the realization of some interfaces and some technologies.At the same time,the significance of teaching big data is indicated in the form of data volume.
