Group discussion, teacher-student discussion is very important for student learning, but there are many restrictions in the implementation of regular classes, while the hybrid teaching and curriculum sharing model is an important way to promote learning effectiveness bull bear. 1. Mixed teaching: MOOCs + flip the classroom "Mixed teaching" is the new trend of current international educational technology development. It combines the traditional face-to-face teaching and network E-learning the advantages of both, with the help of interactive web-based learning platform to build a large number of online learning videos for students to learn; the same time through face-to-face interactive classroom discussions, students Q & Comprehensive ability of students. Hybrid teaching allows students to learn to build their own knowledge structure, so that teachers have more time to communicate with students. This teaching mode has realized three major changes: from passive learning to active learning, from the teaching mode to the inquiry mode, and from individual learning to group learning. Hybrid teaching has many advantages: (1) online tutorials can be repeatedly studied to help solve the problems that students do not understand; (2) students schedule their own learning and make efficient use of time; (3) students independently decide on the difficulty and content of learning; (4) to avoid the teacher repeated mechanical work; (5) transparent teaching, quality control, traceability; (6) the learning effect of transparency, timely feedback of students can be traced back; (7) (8) students to express and think ability to get exercise and training wine class. The mainstream form of blended instruction is "flip the classroom." The specific practices are as follows: teachers first create video and ask questions; students can learn the video content before class, find information and conduct self-study and deepen understanding through group discussions; face-to-face communication between students and teachers in class, student reports on learning outcomes, teacher guidance, Solution. "Flip class" let students become the protagonist of learning,In addition to this, the pioneering lunar mapping techniques developed by the Department of Land Surveying and Geo-Informatics has been deployed in the topographical analysis and landing site selection of Chang. This is a huge milestone in the history of hk research studies in related to national projects.
