Comparative Research On Instructional Design Of Four Types Domestic Online Courses

Using Content Analysis, the article took four types domestic online courses as the object of study, such as quality video open class, high-quality goods resource sharing lessons, micro lessons and MOOCs. Starting with the five elements of instructional design, this paper anlyses form five aspects about the teaching goal, learner characteristics, teaching strategies, learning environment and teaching evaluation, doing a comparative study on the five teaching design dimensions of the four types network curriculum,which in order to explore the construction of the four categories network courses and put forward their applicability.Comparative analysis showes that most theme of the courses are not clear and their content are fuzzy, only high-quality goods resource sharing lessons conform to the standard. At present, different academic season prefer different network curriculum, the number of quality video open class, high-quality goods resource sharing lessons and MOOCs focus on college students, which micro lessons focus on junior middle school. Micro lessons' video recording is given priority to the picture in picture technology and the other three kinds of network courses prefer outside recorded inside hybrid switch. The enthusiasm of interaction between students and teachers is not high. The course type of boutique video courses, high-quality goods resource sharing lessons and MOOCs focus on professional basic courses and public elective courses, mostly the micro lessons impose compulsory courses. Disciplines focus on science and technology, but micro gives priority to the three main subjects such as C hinese, mathematics and English of junior middle school. Most teaching evaluation of the network courses is not perfect, simple and lacks of initiative.The research showes that the construction of network courses should have clear teaching goal and the teaching evaluation should be improved. It is necessary to broaden the object of the network courses, set up incentive mechanism and enhance the interaction between teachers and students. Courses creators need to improve their technical expression. The use and construction of the network courses should be consistent.
