Design,Development And Application Of Mobile Learning Platform Based On Wechat Miniprogram

The continuous innovation of mobile communication technology and the continuous development of interconnection technology and the constant update of learning concept have given birth to the new learning form of mobile learning.Compared with the traditional classroom teaching,mobile learning is not constrained by time and space,and learners can access learning resources anytime and anywhere.In 2017,WeChat launched the WeChat miniprogram.The appearance of WeChat miniprogram provides a new idea for the development of mobile learning.Compared with native apps and web apps,WeChat has the feature of ‘easy reach,convenient leave',which is very suitable for learners to use fragmented time to carry out learning activities.In 2018,WeChat officially launched the cloud development function.The cloud development function weakened the concept of the back end,provided three major capabilities of cloud storage,cloud functions and cloud databases,and provided a large number of development-related API.Developers do not need to set up a server to implement functions similar to the back end,making it easier for developers to focus on the development of core business on the front end.Developers do not need to set up servers to achieve similar back-end functions,so that developers can focus on the development of the front-end core business.Therefore,this study aims at the complex development process and fewer functional modules of the current mobile learning platform based on WeChat miniprogram,and adopts cloud development technology to carry out the development work to simplify the development process and ensure that the functional modules of the platform meet the needs of teachers and learners.This study mainly adopts the design-based research paradigm,and the specific research contents are as follows:(1)Design: Design the overall architecture and page structure of WeChat miniprogram,and use MINA framework and cloud development function to develop WeChat miniprogram;The function modules of WeChat miniprogram are determined,and six modules are proposed,including "course access module","teaching resource module","interactive comment module","homework display module","after-class exercise module" and "user login module".(2)Development: The preparation work in the process of WeChat miniprogram development,including the account registration of WeChat miniprogram,the selection of development tools and the opening of cloud development function are introduced in detail.At the same time,the realization of each functional module is also described in detail.(3)Application and Evaluation: After the launch of WeChat miniprogram,two courses of Lanzhou University,"Foundation of University Information Technology" and "Blockly Creative Fun Programming",were taken as examples to carry out a trial of WeChat miniprogram and verify the usability of WeChat miniprogram.According to users continue to use "WeChat miniprogram will theory model" prepare the questionnaire,to carry out the investigation and study,results show that the WeChat miniprogram "LZU palm class " in perceived usefulness,and expect to confirm degree,perceived ease of use,customer satisfaction,continuous use will and with good results,comparative advantage and so on six aspects of learners at the end of the trial,is willing to continue to use "LZU palm class".
