近几年来,进入中高等职业学校学习的学生基础普遍较差,大部分学生的认知特点是形象思维长于逻辑思维,实践学习长于理论学习,动手能力长于动脑能力。如果在专业课教学中沿用传统的理论和实习教学各自独立进行的方法,则很难实现“以服务为宗旨,以就业为导向,以能力为本位”的职业教育教学目标。尤其是技术性强,不进行训练难以掌握的课程,如数控编程加工。数控设备种类多样、价格昂贵,由于教学中人机比过大,资金有限,这些给数控实践教学带来了极大困难,数控仿真软件的引入有效解决了这个难题。 In recent years, the foundation for students entering secondary and higher vocational schools is generally poor. Most students’ cognitive characteristics are that their thinking in thinking is longer than that in logical thinking, and practical learning is longer than theoretical study. Their practical ability is longer than that of their brain. If we follow the traditional theory and practice teaching methods independently in the teaching of specialized courses, it is very difficult to achieve the goal of vocational education of “serving for the purpose, taking the employment as the guidance and taking the ability as the basis”. Especially technical, training difficult to master the course, such as CNC programming. The variety of numerical control equipment, expensive, due to excessive human-machine teaching, limited funds, which brings great difficulties to CNC practice teaching, the introduction of numerical simulation software to effectively solve this problem.
