With the comprehensive development of quality education, many schools are becoming more and more stringent in the assessment of students’ hands-on ability and operation ability. The mechanical profession is a very practical profession, and the knowledge of various mechanical principles is profound and complex, so in order to improve students’ understanding of mechanical principles and at the same time improve students’ mechanical design level, it is necessary to actively strengthen the experimental teaching efforts. Currently some institutions of mechanical principles and mechanical design teaching away from the fundamental purpose of practical education, so that mechanical principles and mechanical design experimental teaching mode can not meet the requirements of development, many years of teaching experience and facts prove that in the process of teaching mechanical principles and mechanical design, the use of traditional classroom theory teaching and teaching method is no longer applicable.
In the era of quality education, mechanical principles and mechanical design teaching should pay more attention to practical education, with experimental teaching as the core, the students’ hands-on ability to cultivate.
Mechanical principles and mechanical design experimental teaching common problems
1. Experimental teaching concept is old
At present, many teachers in the process of teaching mechanical principles and mechanical design, although they began to pay attention to experimental teaching, the experimental course as an important part of the teaching of mechanical principles and mechanical design, but in the teaching process did not correctly recognize the objectives of experimental teaching of mechanical principles and mechanical design, the understanding of the experimental education objectives is not very clear, thus leading to mechanical principles and mechanical design experimental education level is not high.
2. Experimental teaching methods are relatively old
Teaching methods are influenced by the teaching philosophy, mechanical principles and mechanical design experimental teaching is bound by the traditional education concept, in the actual teaching process teaching methods are relatively old, some teachers only according to the syllabus textbook to explain the experimental content, ignoring the subjectivity and enthusiasm of the students to stimulate, thus leading to many students although the completion of the experimental learning, but did not master the real practical skills, from The content learned from the experiment is not much.
3. Insufficient hardware facilities
Experimental teaching can not be separated from a variety of experimental facilities and equipment, in the process of education and teaching, the school did not actively strengthen the construction of experimental bases, resulting in the mechanical principles and mechanical design experimental teaching process of hardware facilities and equipment can not meet the teaching requirements, the impact on the level of mechanical professional teaching.
Mechanical principle and mechanical design experimental teaching innovation strategy
1. Change the teaching concept
In mechanical education, mechanical principles and mechanical design is an important and basic content, experimental teaching is an important way to improve students’ understanding of this engineering specialty, mechanical principles knowledge is more abstract, complex, mechanical design requirements are high, many students only by theoretical knowledge on the textbook, and can not grasp its deep meaning.
In this regard, it is necessary to strengthen the importance of experimental teaching, to clarify the purpose of experimental teaching of mechanical principles and mechanical design, to incorporate experimental teaching into the teaching tasks of mechanical principles and mechanical design, to cultivate students’ hands-on ability, independent thinking ability and analytical ability as the main goal, to pay attention to practicality in the process of setting up mechanical principles and mechanical design courses, teaching evaluation and teaching activities, and to consider Students’ learning basis, design experimental projects step by step, and promote the improvement of students’ learning level.
2. Improve the experimental teaching mode
2.1 Strengthen group cooperative experimental teaching. Teaching process is the best process to exercise students’ comprehensive ability level, and students can receive better practical exercise by changing teaching methods in the teaching process. Group cooperative teaching is a more common mode of teaching in the process of quality education, its fundamental purpose is to exercise the students’ ability to work together, can stimulate students’ interest in independent learning, in the process of teaching mechanical principles and mechanical design experiments should guide students to group discussion, analysis of various experimental projects.
For example, in the process of mechanical design, to complete the design of mechanical transmission device, the teacher does not explain, let the students themselves according to what they have learned on the principle of transmission device,?C mechanical composition, design structure, etc. to discuss, and to verify the design program, and then through group cooperation to complete the experimental project, and then the teacher to judge the results of the students’ experimental design. This way can stimulate students’ learning enthusiasm and enthusiasm, and motivate students to learn to think independently, solve various problems and reduce the dependency mentality.
2.2 Change from verification experiments to design and innovation experiments
In the process of teaching mechanical principles and mechanical design experiments, we should pay attention to inspiration, students should develop the habit of thinking, in the process of teaching mechanical principles and mechanical design, we should change from traditional demonstration experiments to participation experiments, from traditional verification experiments to design experiments, traditional experimental teaching is the teacher to explain, students operate, to complete the various experimental content in a step-by-step manner.
In the modern education process, students should be guided to actively participate in the experimental design and verification process, can design experimental projects of different difficulty levels, so that students of different levels can choose experimental projects according to their actual situation, and learn various knowledge from the experimental process.
3. Strengthen the improvement of hardware facilities and equipment
In the experimental teaching process of mechanical principle and mechanical design, we should actively strengthen the laboratory construction, supplement some new machinery and typical mechanical models and objects, we can collect the failed parts or mechanical equipment of some enterprises, which can be used for students to strengthen their cognition of mechanical components and mechanical principles, and deepen their understanding of the working principle of machinery through practical operation of machinery, so as to help students Conduct experimental design and complete mechanical design tasks.
