【摘要】：随着人工智能技术和机器人技术的发展,机器人将拥有广泛的知识覆盖面与高度智能化水平,它为实现个性化教学和因材施教提供了一种可能,必定会为教育领域带来颠覆性的改变。在教育机器人的重多研究方向中,机器人辅助教学的研究还处于起步阶段,国内外的部分研究机构已开展了相关研究。机器人技术是辅助教学的手段,而“辅助教学机器人”作为实施机器人辅助教学的主要工具之一,目前仅仅是概念性的产品。机器人应用于教学过程,必将改变传统的课堂教与学的方式,也会促进教师工作的转型。本论文以机器人辅助教学作为研究对象,分别从理论和实践的角度展开研究,探究机器人应用于课堂教学实践的思路和方案,以期为机器人辅助教学领域带来突破和发展。本论文的主要研究工作如下:1.针对目前机器人辅助教学缺乏教学理念指导的问题,在建构主义教学设计的基础上,结合机器人的功能特点,提出一种基于建构主义的机器人辅助教学设计模式。借助系统动力学模型思想构建了教学设计系统变量集,并采用结构方程模型建模方法建立了教学设计模式的量化模型。2.分析了机器人辅助教学系统构成的核心要素及其相互关系,对C-RAI教学设计中的“建立学习定向点”和“探究学习”两部分进行细化,结合机器人技术和多媒体技术,分别提出机器人课堂讲授模式和机器人在线答疑模式。3.在综合分析RAI教学中机器人的功能需求的基础上,设计一款适用于RAI的辅助教学机器人,采用“机器人躯干+固定式底座”的人形结构设计,采用分层控制思想来架构机器人控制系统,实现机器人机械运动和语音合成等基本教学功能。并利用ROS MoveIt来搭建机器人的运动规划平台,对机器人运动进行模拟和仿真。4.根据C-RAI教学设计模式的基本框架完成详细的教学案例设计,将辅助教学机器人作为辅助教学的工具,应用于C-RAI教学案例,实施RAI教学实践。通过对比分析和调查分析的手段对教学结果进行分析,实践证明RAI这种新型的教学形式具有可行性,实现以学习者为中心,教师为主导,机器人为辅导的新型教与学的方式。
[Abstract]:With the development of artificial intelligence technology and robot technology, robots will have a wide range of knowledge coverage and highly intelligent level. It provides a possibility for individualized teaching and teaching students according to their aptitude, and will certainly bring subversive changes to the field of education. In the research direction of educational robot, the research of robot assisted instruction is still in its infancy, and some research institutions at home and abroad have carried out related research. Robot technology is the means of auxiliary teaching, and "auxiliary teaching robot", as one of the main tools to implement robot auxiliary teaching, is only a conceptual product at present. The application of robot in teaching process will change the traditional way of classroom teaching and learning, and will also promote the transformation of teachers' work. In this paper, robot assisted instruction is taken as the research object, which is studied from the point of view of theory and practice, and the ideas and schemes of robot application in classroom teaching practice are explored in order to bring breakthrough and development to the field of robot assisted instruction. The main research work of this paper is as follows: 1. In order to solve the problem of lack of teaching idea guidance in robot assisted instruction at present, a robot aided instruction design mode based on constructivism is proposed on the basis of constructivism teaching design and combined with the functional characteristics of robot. With the help of the idea of system dynamics model, the variable set of teaching design system is constructed, and the quantitative model of teaching design pattern is established by using structural equation model modeling method. 2. This paper analyzes the core elements of robot aided instruction system and their relationship, refines the two parts of C-RAI teaching design: "establishing learning orientation point" and "inquiry learning". Combined with robot technology and multimedia technology, the robot classroom teaching mode and robot online question answering mode are put forward respectively. Based on the comprehensive analysis of the functional requirements of robots in RAI teaching, an auxiliary teaching robot suitable for RAI is designed. The humanoid structure design of "fixed base of robot torso" is adopted, and the hierarchical control idea is adopted to construct the robot control system to realize the basic teaching functions such as robot mechanical motion and speech synthesis. ROS MoveIt is used to build the robot motion planning platform, and the robot motion is simulated and simulated. 4. According to the basic framework of C-RAI teaching design mode, the detailed teaching case design is completed. The auxiliary teaching robot is used as the auxiliary teaching tool, which is applied to the C-RAI teaching case and the RAI teaching practice is carried out. By means of comparative analysis and investigation and analysis, the teaching results are analyzed. The practice proves that RAI, a new teaching form, is feasible and realizes a new way of teaching and learning, which is learner-centered, teacher-led and robot-guided.
