The Visualization Research And Implementation Of Online Educational Data

With the rapid development of the Internet,more and more people pay attention to the online learning platform.In the network information technology,online learning has been at the forefront of the times,the students have no need to personally to the classroom lectures,as long as through the network will be able to learn and whenever and wherever possible,with humane education,24 hours online Q & A,low tuition,reduce the unfair distribution of educational resources and other benefits.In addition,the country also develops vigorously Internet plus network education,the network university diploma has been widely recognized by the society.Therefore,more and more students choose to study on the internet.At present,many of the problems encountered during the development of online learning platform,the teachers can't face-to-face interact with the students,for students of the situation can not be a good solution,a great impact on the traditional teaching mode.The other students have data too fragmented,individualized overall situation,it is difficult to fully grasp the teaching of students;for students who have no serious study and complete the quality and quantity of teacher assignments,educators from the network are difficult to investigate and understand;educators for students to learn everyday activity do not understand the lack of interaction,the enthusiasm of teaching itself is also very poor;educators are not an effective way to understand students' daily hot,can not solve the problem of students.For this reason,this paper attempts to study the students in the process of online learning in the process of data fragmentation,visualization work.Based on the one-dimensional data,online learning platform on the two-dimensional data,the hierarchical structure of these simple data types are simple visualization of online learning,for visualization of the complex structure of data platform are studied carefully.This paper introduces the spring model graph layout algorithm,and based on the spring model on the layout of the FR algorithm,and the application in FR algorithm,simulated annealing algorithm or Barnes-Hut algorithm can improve the visual effect of different extent.In order to study and test the effect of visual algorithm optimization,a visual testingsystem is designed and developed.The development and testing system plays a key role in the successful completion of the research and development work.In addition,in order to online learning platform can be easily applied to the visual function of educators,specially prepared the corresponding application interface.It makes use of the network platform of the school network and the continuing education college to do the visualization work.The ultimate purpose of this paper is produced by the online learning platform for data visualization work,found in online education and lack of oversight,in order to improve the teaching quality of educators in the online platform,and to understand the situation of students,improve teaching methods.
