《机械制图》是机械专业中一门实践性较强的基础课,它主要培养学生看图、画图及空间思维能力。由于职校生本来基础就差,各科知识跟不上,而传统的教具、模型很有限,挂图又显得不够灵活,因此,常常是教师在讲台上描述比划半天,学生们还是一脸茫然。近几年,随着计算机技术的飞速发展及现代教学设备的普及,使得集音、图、像于一体的多媒体教学手段迅速进入课堂。其新颖、直观、形象、动态的特点受到广大教师的普遍好评,并在具体教学中起着举足轻重的作用。 Mechanical drawing is a practical basic course in mechanical engineering. It mainly develops students’ drawing, drawing and thinking skills in space. Due to the poor foundation of vocational school students, the knowledge of each subject can not keep up. However, the traditional teaching aids and models are limited and the flip charts are not flexible enough. Therefore, teachers often describe the gestures on the podium for a long time and the students are still at a loss. In recent years, with the rapid development of computer technology and the popularization of modern teaching equipment, the multimedia teaching methods integrating sound, picture and image have quickly entered the classroom. Its novel, intuitive, visual and dynamic features are widely praised by the majority of teachers and play an important role in specific teaching.
