【摘要】：随着现代科学技术的发展,社会对人才的需求从单一向多元化方向发展,毕业生具有基础理论知识适度、技术应用能力强、知识面较宽、素质高等特点,中等职业教育人才培养模式也发生了改变,即以培养技术“应用型”人才为根本任务,以适应社会需求为目标,以“应用”为宗旨构建课程和教学内容体系。这使中职教育的教学思想发生改变,各中职学校为提高自身的竞争力,对学校的课程设置、教学内容做了一系列的教育改革实践。计算机技术的不断发展,CAD/CAM自动制造技术在机械行业中得到广泛应用,这就需要学生有三维建模的能力以及逻辑思维能力,这种能力的培养需要学生主动建构知识框架。因此,本文研究机械制图教学实践的根本意义不在于如何改进学生知识吸收的效果,而在于如何通过引入新技术(特别是新媒体技术)提升学生相应的基础能力。本文通过解决(1)区分三视图与平面图以建立正确的空间概念体系；(2)建立正确的立体映射机制；(3)建立正确的视图逻辑层次三个关键问题。在建构主义教学理论基础上,将传统与现代教育手段相结合,提出了改进的机械制图的教学设计和实践。本文第四章中,通过对改进的机械制图课程教学设计与实践的效果分析,对比了传统的教学设计效果,证明了所提出新型教学设计的有效性和实用性。
[Abstract]:With the development of modern science and technology, the social demand for talents has developed from a single to a diversified direction. Graduates have the characteristics of moderate basic theoretical knowledge, strong technical application ability, wide knowledge, high quality and so on. The mode of talents training in secondary vocational education has also changed, that is to say, the basic task is to train technical "applied" talents, and the goal is to meet the needs of the society. The purpose of "application" is to construct the curriculum and teaching content system, which makes the teaching thought of secondary vocational education change. In order to improve their own competitiveness, each secondary vocational school has set up the curriculum of the school. The teaching content has done a series of educational reform practice. With the continuous development of computer technology, CAD / CAM automatic manufacturing technology has been widely used in the mechanical industry, which requires students to have the ability of three-dimensional modeling and logical thinking ability. The cultivation of this kind of ability needs the students to construct the knowledge frame actively. Therefore, the fundamental significance of the study of mechanical drawing teaching practice in this paper is not how to improve the effect of students' knowledge absorption. It lies in how to improve students' basic ability by introducing new technology (especially new media technology). This paper sets up a correct concept system of space by solving the problem of distinguishing three views from the plan. (2) establishing the correct stereo mapping mechanism; On the basis of constructivism teaching theory, combining traditional and modern educational means, this paper puts forward the teaching design and practice of improved mechanical drawing. In chapter 4th, by analyzing the effect of the teaching design and practice of the improved mechanical drawing course, the author compares the effect of the traditional teaching design, and proves the validity and practicability of the new teaching design.
