【摘要】：国家十三五规划中提出推行产教融合、校企合作的模式,积极培养应用型和技术型人才,并且强调全面实行通识教育和专业教育相结合的培养制度,为了培养学生的创新精神和创造力,更是需要深化实践教学。越来越多飞速发展的高新技术逐步深入教育教学中,AR技术则是其中之一。AR(增强现实,Augmented Reality)是通过计算机技术将现实世界中不存在的虚拟对象重合在真实环境中,也就是把虚拟对象和真实世界重合在同一空间的一种技术。普通高中通用技术属于技术操作型课程,主要培养学生的技术素养。而高中通用技术实验课程教学的开展由于对课程重视程度不够,教育经费不足导致实验设备的缺乏,教学设备使用率不高,部分实验存在危险性以及教师缺乏有效的教学经验等因素的限制,达不到课程的教学目标。本研究以AR技术为基础,将其在计算机中建立的虚拟世界和现实世界的信息交互的核心思想应用到实验演示平台的体系架构中,开发出一套基于AR的实验演示平台,结合传统教学的模式,将现有的实验设备图像形式在教学及学习过程中转化为立体的、动态的、交互性的数字化实验设备。并对整个教学及学习过程进行准实验研究,从而对平台的科学性、逻辑性、易用性等方面进行实践的验证。通过对学习者使用平台后的学习成果进行检验、分析等,对该实验演示平台进行不断的优化和完善,使之成为有利于教学及学习的实验演示平台。解决学校对课程的重视程度不够、教学设备使用率不高、教师经验不足以及实验存在的危险性等问题。对于学习者来说,不仅提高学习兴趣,同时有助知识的建构并提高教学效果。对于教学者来说,优化实验课程教学,提高教学质量。同时为新一代的实验演示平台提供理论依据和应用模型,也为其他技术性课程提供技术指导。
[Abstract]:In the 13th Five-Year Plan of the State, it was proposed to promote the pattern of integration of industry and education, cooperation between schools and enterprises, and actively train applied and technical talents, and emphasized the comprehensive implementation of the training system of combining general education with professional education. In order to cultivate students' creative spirit and creativity, it is necessary to deepen practical teaching. More and more rapid development of high and new technology in education and teaching is one of the AR (augmented reality) through computer technology, the virtual objects that do not exist in the real world are overlapped in the real environment. That is, a technology that overlaps virtual objects with the real world in the same space. General technology in senior high school belongs to technical operation course, which mainly trains students' technical literacy. However, due to the lack of attention to the curriculum, the lack of educational funds, the lack of experimental equipment and the low utilization rate of teaching equipment, Some experiments are dangerous and teachers lack effective teaching experience and so on, which can not reach the teaching goal of the curriculum. Based on AR technology, the core idea of information interaction between virtual world and real world is applied to the architecture of experimental demonstration platform, and a set of experimental demonstration platform based on AR is developed. Combined with the traditional teaching mode, the existing experimental equipment image form is transformed into three-dimensional, dynamic and interactive digital experimental equipment in the process of teaching and learning. And the whole teaching and learning process of quasi-experimental research, so as to the platform of scientific, logical, easy to use and other aspects of practical verification. Through the test and analysis of learners' learning results after using the platform, the experimental demonstration platform is continuously optimized and perfected to make it an experimental demonstration platform conducive to teaching and learning. To solve the problems such as insufficient attention to curriculum, low utilization rate of teaching equipment, lack of teachers' experience, and the danger of experiment, etc. For learners, it not only increases their interest in learning, but also helps to construct knowledge and improve teaching effect. To the teacher, optimize the experiment course teaching, improve the teaching quality. At the same time, it provides theoretical basis and application model for the new generation of experimental demonstration platform, and also provides technical guidance for other technical courses.
