Based on the project practice of education technology course as an example, this article has set up a platform of experimental teaching based on Moodle platform. It mainly illustrates from the course management, self-regulated learning test,toprocedural evaluation and so on. This platform gives full express to the advantages of double main teaching model in which the teacher is dominant while students are the main body, and it has significance on reference to the practical and experimental curriculum.展开更多

文摘Moodle platform is the international popular course management system. Based on the project practice of education technology course as an example, this article has set up a platform of experimental teaching based on Moodle platform. It mainly illustrates from the course management, self-regulated learning test,toprocedural evaluation and so on. This platform gives full express to the advantages of double main teaching model in which the teacher is dominant while students are the main body, and it has significance on reference to the practical and experimental curriculum.
