Vocational Study Mechanical Drawing Of Instructional Design And Practice

With the development of modern science and technology, the social demands for talents from single to diversify the direction of development, students with moderate basic theoretical knowledge, technology applied ability, broad knowledge, quality is advanced characteristic, secondary occupation education training mode has also changed, is to cultivate technology "applied" talent as a fundamental task, in order to adapt to the social needs as the goal, to "application" for the purpose of constructing the system of curriculum and teaching content.The secondary vocational education teaching idea change, the secondary vocational schools to improve their own competitiveness, on the school curriculum, teaching content to do a series of educational reform and practice.The continuous development of computer technology, CAD/CAM automatic manufacturing technology in mechanical industry is widely used, which requires students to have three-dimensional modeling ability and logical thinking ability, the ability required students to construct knowledge actively framework.Therefore, this paper studies the mechanical drawing teaching practice of fundamental significance does not lie in how to improve the students’ knowledge absorption effect, but in how the introduction of new technology (especially the new media technology) to enhance students’ ability of corresponding foundationThrough solving (1) distinguish between three views and plans to establish the correct concept of space system;(2) establishing the correct three-dimensional mapping mechanism;(3) to establish a correct view of logic levels are three key problems, in the constructivist teaching basis, traditional and modern education means combines, put forward improvement the mechanical drawing teaching design and PracticeIn the fourth chapter, through to the teaching of mechanical drawing course design and practice effect analysis, contrast the traditional instructional design, instructional design shows that the proposed model is effective and practical.
