Engineering Drawing "multi-media Instructional System Design And Application

With the development of multimedia, modern educational technique and multi- media courseware techniques,multimedia teaching methods are used widely. Modern teaching methods have rapidly developed in these years. Multimedia teaching is an efficient new digital teaching methods. Especially for Engineering drawing which lays heavy stress on"drawing", it is a special important major in teachings because of its special contents,forms and show methods. In this thesis, according to the characteristics and different teaching contents of engineering drawing and it's status in profession, multimedia teaching methods and traditional teaching methods can be combined well.At the same time, according to the characteristics of this course and the different specific characteristics of every student, every chapter, we should design the multimedia teaching well and use reasonably. It is the key of this investigative problem too. This problem creates a new teaching method for engineering drawing. According to the design and applied investigation of this multimedia teaching system,the teaching methods would be modern. At one time,current educational methods and traditional teaching methods (model, wall map, teaching-kinescope)can be combined organically too. The teachers can carry out space transposition between 2D model and 3D model on the computer quickly. So, 3D animation will make the teaching contents more active, intuitive and clear.This thesis is based on the course's teaching characteristic. According to the appliance of the multimedia teaching system, the thesis finishes CAI courseware and introduces the composing, producing, designing ideals of this system. When Authorware is used as compiler platform, we can use goods (AutoCad2008,3dsmax, Authorware, Caxa, Flash) to achieve the compilation of text, sound, picture, cartoon in the multimedia teaching courseware. Establish needed Footage Library according to the form of the database. teaching process would become more direction. The contents of the database can be appended,deleted,altered,editored at any time. Basic materals can be managed and maintained ;teaching contents can be optimized; the structure of teaching can be adjusted. We can establish teaching demonstration ledge by the use of Pro/Engineer,Visual C++,Access, we also can research transformation technology of the virtual solid modeling technology, 3Dmodeling, 3D solid, 2D pattern. So, to some difficult concepts, teaching demonstration ledge can help the students to realize major knowledge and improve learning interest.
