Abstract: In view of the complex knowledge system on agricultural Internet of Things, case teaching playsthe especially important role in deepening the graduate students’ understanding of the basic principles and concepts of agricultural Internet of Things technology, and cultivatingstudents’ ability to analyze and solve practical problems. Combined with the teaching reform of “Agricultural Internet of Things Technology” set up by the agricultural engineering postgraduate program, this paper focusedon the teaching objectives and content of the “Agricultural Internet of Things Technology” course, and collected and analysed four teaching samples, including the data collection, transmission of the Internet of Things and control technology, blueberry facility agricultural production intelligent control, intelligent irrigation IoT equipment integration platform, animal husbandry IoT intelligent sensing system and edible fungus IoT environmental control system. A new teaching mode of multi-stage, multi-level and emphasizing practical operation was formed with “classroom theory teaching + online demonstration + field operation” as the main form. Teaching methods such as project task-driven, heuristic, discussion, and on-site instruction wereadopted. Through practice, theteaching content, teaching modes and teaching methodsof case teacing have achieved the expected teaching goals.

Key words: agricultural IOT technology, case teaching, new teaching mode
