机械工程材料课程教学探讨中英翻译.doc

engineering material course teaching to explore chinese-english translation 机械工程材料课程是机械类专业学生的技术基础课，是一个倾向于叙述性质的课程体系，既有高度浓缩的基础理论，又有实践性很强的操作工艺技术机械类专业教学大纲明确指出，该课程是联系设计类课程与制造类课程的纽带，是从基础课学习转向专业课学习的桥梁，其特点主要表现为“三多一少”，即内容头绪多、原理规律多、概念定义多、理论计算少另外，该课程也是一门与实际工程紧密结合、实践性较强的课程，在整个教学过程中约占 48（含实验 8 学时）学时因此，摆在机械工程材料课程教师面前亟待解决的课题是怎样利用有限的学时和条件，组织和协调好课堂理论教学与实践教学的配合，使学生尽可能掌握、理解该课程内容，进一步探讨如何拓宽学生的专业视野，提高学习兴趣，培养实际动手能力，训练他们系统掌握工程材料综合运用能力，使该课程与后续专业课程融为一体Mechanical engineering material course is a technical basic course for students majoring in machinery, is a tendency in the narrative nature of the course system, both the basic theory of the highly concentrated, and practical operation techniques. Mechanical engineering syllabus clearly pointed out that the course is contacting design and manufacture course of link, the bridge from basic course learning to professional course learning, its characteristic is mainly about “a little“, namely content idea, principle of law, concept definition and theoretical calculation. In addition, this course is a closely integrated with the actual engineering, practical stronger course, in the whole teaching process accounts for about 48 class hours (including eight hours). Before mechanical engineering material course teachers, therefore, subject to be solved is how to utilize the limited class hours and conditions, good organization and coordination of classroom theory teaching and practice teaching, make students master as much as possible, understand the course content, to further explore how to broaden the students' professional vision, improve the learning interest, cultivate the actual beginning ability, train their master engineering material system comprehensive utilization ability, make the course and the follow-up professional courses. 1 本课程在教学体系中的现状1 status in the system of teaching this course of the course object is mechanical professional students, to train mechanical engineer for the purpose of [1]. Mechanical engineer, emphasis of the training is to be able to correct materials, timber, and reasonably selecting machining method, formulation process route, need an engineering design and manufacturing materials closely related knowledge and skills, which understand the characteristics of the material in the process of shaping and use, to grasp the essence of materials. So teaching basic requirements must be accord with the actual work to be a mechanical engineer, to put this to use, but also reflects some current teaching process deficiency in [2]. 对于机械工程材料课程教学活动，数学校安排在第三学期进行，授课对象正处于开始专业基础课的学习阶段，缺乏实践经验和机械加工制造工艺的感性知识，因此进入专业基础课学习时感到茫然，学习欲望不强烈。

另外，该课程繁杂、枯燥、抽象、灵活的特性，要求学生具备较好的综合能力，较强的灵活运用能力但学生的思维方式、学习方法、掌握能力均不太适应，往往事倍功半，学习效果不明显，从而影响了学习的积极性For mechanical engineering material teaching activities, the paper by paper union collect several school arranged in the third semester, the teaching object is at the stage began to professional basic course of study, lack of practical experience and perceptual knowledge of mechanical processing manufacturing process, thus bewildered when entering the professional basic course learning, learning desire is not strong. In addition, the course is multifarious, boring, abstract, flexible features, students are required to have good comprehensive ability, strong ability of flexible use. But students way of thinking, learning method, grasps the ability were not too orientation, often the wasted effort, the learning effect is not obvious, thus affecting the enthusiasm of learning. 近几年，课程教学改革不断深入，随之而来的是不断压缩课时，而教学内容有增无减。

因此，为了完成教学工作，大多数课堂教学仍以灌输知识为主，教师把主要精力放在按规定学时把所有的教学内容灌输给学生，偏重课程知识、内容孤立传授，而对学生如何运用 recent years, the curriculum reform unceasingly thorough, followed by continuous compression class, the teaching content increase. Therefore, in order to complete the teaching work, the majority of classroom teaching is still mainly on knowledge, teachers focus on school required all the lessons of the teaching content to students, curriculum knowledge, instruction content isolation of lay particular stress on, and on how students use knowledge ability to solve practical problems, analysis the lack of training. Basic is in a state of passive accept students in the classroom, is not conducive to mobilize students' learning enthusiasm, initiative, teaching efficiency is not high, directly show the course completion test scores on the low side. 实践教学是人才培养的重要环节，在学生能力和综合素质提高方面有其独特的作用。

但目前机械工程材料课程的实验大多属于验证性实验，即学生根据实验指导书按部就班操作即可得到实验结果，几乎不需要思考，因此学生对实验课的投入不够，缺乏兴趣另外，许多院校在实践过程中普遍存在一些问题，如学生逐年增多，而实验设备得不到及时更新和购置；因课时限制，学生不能。
