The Research Of Teaching Case Design Under The Environment Of Information Technology

The disconnection of educational theory and practice is a problem commonly existed in the teacher education.The application of case teaching method can effectively solve this problem,improve the pertinence and adaptability of teacher education and to a certain extent promote the professional development of teachers.The key to the success or failure of case method lies in the design and development of teaching cases.For this reason,this study launches research on the analysis of the current situation of case methods and teaching cases,concept definition,theoretical basis,design and development of teaching cases,and application experiments of teaching cases and it tries to construct the teaching design model of teaching cases,it also develop six teaching cases for the curriculum of Modern Educational Technology to carry out experimental research and provides reference and reference for the development and application of teaching cases.First of all,on the basis of summarizing the development and application of teaching cases both in China and abroad,the definition of the teaching case is defined according to the opinions of experts and scholars in China and abroad on the teaching case concept.Secondly,inspired by Dick-Kerry's teaching design model and teaching-centered teaching design model,according to the proposed three-point model construction principle,teaching design model for teaching cases was constructed.Thirdly,according to the instructional teaching design model of the teaching case constructed,the corresponding text teaching case was developed in conjunction with the main contents of the "Modern Educational Technology" course,and a video teaching case was made.Finally,in the application of experimental teaching cases,by taking the undergraduate students as the subject of study and through the random determination of the experimental group and the control group,the six teaching cases of Modern Educational Technology are designed and developed by Baidu Yun disk as the transmission carrier,the WeChat group as the bridge so as to complete the application of teaching cases in the information technology environment.The statistical analysis of the data collected from the experiment shows that the learning effect of learners using teaching cases is better than that of traditional classroom teaching.
