The Design And Application Of University Physics Difficulties SPOC Course Resources

With the development of education informationization and the "Internet +" strategy,the revolution of online teaching resources to traditional education have been attracted worldwide attention in nowadays.MOOC online teaching platform,which is characterize by "massive and open" features,have been widely known in education industry,but the intrinsic defect has also been involved in dispute,such as the high dropout rate,low utilization and so on.In this case,The SPOC,which is more pertinence and privacy,was rise up as a powerful strength for online education.Meanwhile,the amount of physics knowledge has increased exponentially over the past few centuries so that the content of college physics course become more and more abundant.It makes the student be very puzzled in physics lessons even the so-called good student.That means the requirement of the student on physics guidance curriculum should not be overlooked.The pertinence feature of SPOC is satisfied well with the personalized demand on guidance curriculum resources.Hence we design the SPOC course resources carefully from the course difficulty standpoint so as to construct a more efficient ways to impart knowledge to help student learn how to learn.Based on course difficulty model,cognitive load theory and the constructivism theory,we using the literature analysis,interview,questionnaire methods to carry out this research.Firstly,the content analysis method is used to reorganize the current research situation of SPOC teaching mode,teaching video and course difficulty.In this paper,we construct the objective difficulty model of physical knowledge point based on the research of course difficulty.Utilizing this model,we analyzed the difficulty of Electricity section of college physics.Then,we conducted a survey of learners’ learning background and the difficulty of studying physics.By analyzing the present situation of university physics learning,we can preliminary understand the difficulty of college physics for the student.And on this basis,we elaborate the design of the college physics SPOC resources,and proposed the development process of video resource,the resource design scheme for the knowledge point and the application model of SPOC resources in actual teaching effort.Finally,we conduct empirical research on the cases of "dielectric polarization" and "Gauss theorem in dielectrics".And we developed and applied the case to small-scale testing to evaluate the practical application of resources.The results of the evaluation show that the resources,which are developed by the complexity of knowledge,can be remarkably increasing the college physics record of students and to help the student to understand the college physics course more sufficiently.Based on the difficulty model of physical knowledge point,this paper analyzed the objective difficulty of knowledge points and the subjective difficulty of learners.And the SPOC video resources designed on this basis are important auxiliary resources for students’ after-class learning,which is an efficient ways to improve the ability to learning independently.This work has the practical reference significance for the online teaching of college physics course.
