Design And Implementation Of K12 Education Online Lesson Preparation System Based On TypeScript

In recent years,with the continuous innovation of various technologies,the Internet is not easily aware of all aspects of our lives,which has stirred up our lives and brought a new way of life.How to change the educational model,combined with Internet technology in all aspects of teaching,is a question worth considering.At present,domestic education-related products are mainly focused on how to lower the learning threshold of all walks of life and promote knowledge sharing.That is,more attention is paid to the student side,and little attention is paid to how to reduce the teaching pressure of teachers.As the most critical link in all stages of education,K12 education has been entrusted with the parents' heavy expectations,and the teachers' work is heavy and trivial.Through the research on the history of the preparation of foreign lesson preparations,the in-depth needs analysis of the online preparation system of K12 education has been carried out on the research and use of influential and teaching-related software products that have been put into operation in China.Five modules,such as picture processing,courseware material,courseware management,and shortcut operation.The text processing and image processing modules are divided into text and image insertion and post-insertion style adjustment operations,which are the key modules of the system.The courseware material module contains a large amount of courseware material for reference during class preparation.The courseware management module shows all the courseware after the user has completed the lesson preparation and provides a variety of courseware management functions.The shortcut module implements a variety of shortcut operations,optimizes system interaction,and enhances the user's preparation experience.The K12 Education Online Lesson Preparation System is a componentized project built with TypeScript and React.Due to the relatively high system state and complex structure,Redux and Immutable.js are used as the manager of the application state.The system involves frequent operations of text and images.In order to improve the performance of the page,RxJS is added to convert the data in the page into a data stream,which makes processing asynchronous data simple and convenient.In general,the design and implementation of the K12 education online preparation system will make teachers feel the benefits of Internet popularization.
