In the theory and practice of robot education in K-12, it is widely believed that robot education is to teach students how to design and build autonomous robots. However, an edutainment robotic system called robotic-computer interactive system (RCIM) also deserves our attention. In view of this, this paper adopts literature research method and analyzes the composition of robot hardware and computer program from the perspective of input and output combined with the features of RCIM. And it also discusses the specific application types of RCIM from two dimensions of function and human-computer interaction. Then this paper constructs an interesting interactive model (IIM), which is both instructive and operational based on project teaching model. Experimental research shows that compared to traditional teaching models, IIM can significantly improve students' attitudes towards learning and the integrity and interactivity of students' artifacts as well.%在中小学机器人教学的理论与实践中, 普遍认为机器人教学就是让学生设计和制作能够独立运行的机器人作品, 而忽略了另外一种颇具寓教于乐意义的机器人联机交互系统.为弥补这一缺失, 文章采用文献研究方法, 结合机器人联机交互系统的特点, 从输入、输出的角度刻画了机器人硬件端与计算机程序端的组成结构, 并从作品功能和人机交互方式两个角度分析了其具体应用类型;以此为基础, 结合项目教学模式, 构建了一个兼具指导性与操作性的趣味交互型教学模式.实验研究表明, 相比传统项目教学模式, 趣味交互型教学模式能够明显改善学生学习机器人的态度及学生作品的完整性与交互性.
