《农业物联网技术》研究生课程教学案例内容建设探索

Content construction for postgraduate course of agricultural IOT technology based on case teaching

针对复杂的农业物联网知识体系,如何加深研究生对农业物联网技术的基本原理和概念的理解,培养学生分析问题和解决实际问题的能力,案例教学尤为重要。结合农业工程专业开设的《农业物联网技术》研究生课程教学改革,以科研反哺教学,围绕《农业物联网技术》课程教学目标和内容,梳理并凝练了物联网数据采集、传输及控制技术教学案例,包括蓝莓设施农业生产智能控制、智能灌溉物联网装备集成、畜牧养殖物联网育繁智能监控系统和食用菌物联网环境控制系统等。形成了课堂理论教学+网络在线演示+现场操作等分阶段、多层次、重应用、动手操作的教学新模式,采用了项目任务驱动、启发式、讨论式、现场指导式等教学方法。经实践,其案例教学内容及教学模式与方法达到了预期的教学目标。

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.
