Abstract. SPOC (small private online course) has recently evolved into a typical representative in post-MOOC (massive open online courses) times. Current researches about SPOC mainly focus on blended learning mode, teaching process, and teaching mode etc., paying less attention to online behaviors of learners. Based on online platforms of the general knowledge course Game Theory, this paper analyzes and researches online behaviors of SPOC learners. In addition, this paper summarizes differences of SPOC and MOOC in online learning behaviors by collecting online learning behavioral data of 145 learners and investigating their online behavioral characteristics during their learning process. The research reveals, learners are fond of video media in terms of the communication form, tend to answer questions instead of coming up with their own questions in terms of interactions, and focus on quizzes and homework due to pressures of credits.

The application of video resources has become extensive, and the demand to the video retrieval is growing intensely. How to access the video clips expected quickly and accurately from the massive video database has become the key issue in the development of the video information retrieval. The existing retrieval process based on keywords is no longer meeting the needs of users. Thus, video retrieval systems based on content have been proposed and become a hotspot of this field. This paper researches on teaching video retrieval process based on content, explores the search process and the key technologies for teaching video resources retrieval, which is applied in the "Course Review Platform on Basic Education".

Situated in the network-based learning environment, the non-rationality of the learners in the virtual learning community makes it a demanding for the establishment of the incentive mechanism to ensure the success of the learning community. First of all, this paper gives an outline to the prospect theory and the necessity e of the establishment of incentive mechanism in virtual learning environment is also illustrated. Then based on the theoretical framework of the prospect theory, some suggestions are put forward such as improving the network-base learning environment by the pulse type, dividing the awards program, modifying the performance manifestation, increasing the punishing measures for the low probability.
