Research On The Design Of Online Learning Activities To Promote The Development Of Critical Thinking

The rapid development of "Internet + education" accelerates the promotion and popularization of education informationization and education modernization,and also promotes the deep integration of education and technology.At present,more and more information technology means have entered the classroom,providing opportunities for the online learning activities supported by the information technology environment to promote the cultivation and promotion of students' high-level thinking.At a time when technology promotes educational change,it is not only limited to students' academic performance,but also focuses on cultivating students' high-level thinking and skills,such as critical thinking.As an important part of core literacy,critical thinking is indispensable for human development.The cultivation of critical thinking will not only improve the students' learning effect and the teaching efficiency of teachers,but also enhance students' way of thinking and cultivate students' information literacy and skills to adapt to the future life and social development rhythm.This study mainly uses "Ketangpai" as the online learning platform,taking the"Professional English" course as the practical goal,and taking the 2018 education technology graduate students in a university in Shanghai as the research object,and designing online learning activities to promote the cultivation and promotion of students' critical thinking.First of all,combing,analyzing and researching a large body of literature related to critical thinking and online learning activities,aiming at determining the theoretical framework of research,laying a theoretical foundation for the design of online learning activities to promote the development of students' critical thinking,and providing research and design direction.Secondly,using the design research method,the learning environment model of the online learning activity,the learning activity content,the learning activity process,and the online learning activity practice model are designed to provide a platform for the next classroom practice.Then,the case study method was used in the practice and development of a one-semester online learning activity,taking the postgraduate class of 2018 education technology in a university in Shanghai as an example.In the process of practice,mainly guide students to familiarize themselves with the classroom and quickly participate in online learning activities,and actively participate in online synchronous or asynchronous communication discussions.And collecting a large number of online discussion utterances based on "Ketangpai",which provides an important basis for the evaluation of students' critical thinking and promotion;Then,through the collation,coding and analysis of the student's online discourse,using social network analysis and visualization methods,depicting and sketching the dynamic process of cultivating and elevating students' critical thinking.In addition,combined with in-depth interviews with students,further understanding and evaluating the effectiveness and scientificity of online learning activities designed to promote students' critical thinking development Finally,summarize,reflect and forecast the entire study,and provide reference and experience for the development and implementation of subsequent similar researchThe study found that online learning activities based on "Ketangpai" have a positive effect on promoting the cultivation and promotion of students' critical thinking(I)As the course progresses and online learning activities advance,the change of students' critical thinking dimensions gradually shows the trend of "gradual to higher-order dimensions".And through the path of "knowing?understanding?analysis?evaluation ?creation ?reflection",each dimension interacts with each other and complements each other.(II)Through in-depth interviews and analysis of students,it is found that:through the participation of online learning activities,the critical thinking has been significantly improved,not only in the process of discussion with other people,but also in daily life,study and work.The purpose of this study is to promote the development of students' critical thinking by designing online learning activities.On the one hand,it provides meaningful guidance for the design of classroom online learning activities in the era of "Internet + education",on the other hand,it also provides reference and lessons for cultivating and enhancing students' critical thinking.
