Key technologies and case implementation of online course

To adapt to the needs of teaching modes such as network distance education and mobile online learning, and overcome the space-time limitation of traditional offline education, the construction of online courses has become an important task of informatization in education. The research analyzes several key technologies for the construction of online courses and proposes solutions for making dynamic maps and demonstration animations, sharing relevant teaching resources, cloud classroom design, special experiment design, and online testing and question & answer (Q & A). On this basis, with the index system of "Modern Distance Education Standards" as a reference, the national standard and evaluation plan of online courses as guides, and computer technology and multimedia technology as means, the research develops an online course case of Marine Geographic Information System (MGIS). Based on the.NET platform, construct a teaching resource website supporting MGIS. The online course and its supporting teaching resources website have realized the characteristic function of personalized self-learning, dynamic demonstration of knowledge, online testing according to different learning stages, interesting experiments to stimulate learning enthusiasm, intelligent feedback learning effect, and so on. Through application and practice in teaching, the website of online courses and resources has achieved a good teaching effect.
