Research On The Data Visualization Of Blended Teaching Based On The Platform Of Rain Classroom

With the rapid development and in-depth application of modern information technology,the use of information technology to promote education and teaching innovation has received increasing attention.The combination of online and offline teaching combined with the advantages of traditional teaching and online learning is considered to be an important starting point for advancing education informatization and classroom reform.In the actual mixed teaching process,a large amount of online and offline teaching related data is recorded on the teaching platform.Due to the constraints of educators' time and energy,information literacy and other factors,a large amount of teaching data collected is often not analyzed in depth,and there are problems such as a single presentation mode,unintuitive,and ineffective application,which seriously hinder the advantages of mixed teaching.Therefore,the study applies data visualization technology to mixed teaching,and presents teaching data in a more intuitive way of expression.It can improve the speed of people's understanding and analysis of data,and help educators to more effectively discover the underlying data.Information is important to better review and improve the teaching process.This article takes various teaching-related data generated in the process of mixed teaching as the research object,and starts with the mixed teaching based on the Rain Classroom platform.Through literature review and analysis and related technology frontier investigation,the visualized method and application of mixed teaching data based on the Rain Classroom are carried out.In-depth research.It mainly includes the following three aspects:First,the core concepts and theoretical foundations related to the research on the visualization of the teaching data based on the Rain Classroom platform were clarified,and the elements and implementation process of the mixed teaching environment based on the Rain Classroom were analyzed.The Rain Classroom platform was generated from three stages before,during,and after the lesson.Among the various teaching data,a corresponding hybrid teaching data collection model based on the Rain Classroom platform was constructed,including student data,teacher data,and teaching dynamic generation data.Secondly,combined with the general process of data visualization,a visual analysis framework of mixed teaching data was constructed.The realization process and mechanism of mixed teaching data visualization were discussed from the two dimensions of timeliness and media form.Numerical values,texts,and numerical and textual information were introduced.The visual processing method of mixed data is discussed,and the interactive presentation process of visualized results is discussed.Finally,the teaching practice research of visualized application of mixed teaching data based on the Rain Classroom platform was carried out.The practice of applying the data visualization results to the public lectures of Teacher Education in "Applied Modern Education Technology" based on the Rain Classroom shows that the experimental class that comprehensively applied the data visualization results achieved better results than the reference classes that did not apply the data visualization results.Teaching effect.The experiment verifies the effectiveness of the visualization application of mixed teaching data.This research also gives suggestions for optimizing the application strategy of data visualization technology in mixed teaching,hoping to provide a reference for the implementation of data-driven precise teaching process.
