On the "interchangeability and techniques to measure the" project to explore the teaching curriculum

Abstract: Analysis of the <<interchangeability and techniques to measure the>> introduce curriculum reform projects in teaching the meaning, objectives, describes the project pedagogy in the course of implementation, and implementation results and problems. Proof of the main body of students as learning, training project by completing the theory and practice together, not only can improve the theoretical level and operational skills, but also foster a spirit of cooperation and problem solving comprehensive ability.

Keywords: interchangeability and technical measurement, project teaching, Research and Practice

teaching the meaning of Application projects
Modern engineering education is to combine the teaching of engineering practice and training in line with industry needs with the overall capacity and quality of engineering talent in the project of teaching is a competency-based teaching methods, according to the knowledge of the complete project organization, to the students to do, to learn, repeatedly in the project-based learning, learn the necessary knowledge to form a variety of capacities. The idea is to project a relatively independent tasks to the students independently, from the collection of information , program design and implementation to complete the evaluation by the students in charge, teachers play advice, guidance and answers to difficult role, not only to teachers with the knowledge and skills transfer readily available to students, through a project of practice, to make all students understand and grasp the completion of the project's basic requirements for every aspect of the focus of the entire process, difficulties in the process of teaching students to acquire knowledge, apply knowledge to solve problems, discover new knowledge and practical experience, teamwork, communication and exchange with people's capabilities and innovative capacity, to achieve the students the purpose of the overall professional quality.

Application Project Approach curriculum objectives of the reform
Since <<interchangeability and techniques to measure>> of this course the theory is strong, combined with traditional teaching methods, we did some innovation and reform, curriculum reform goals is to train students with tolerance and with other aspects of the theory knowledge and control of both the technical means and methods of measurement, both according to the requirements of the drawings to produce qualified products, but also the quality of correct detection.

Specific terms from the following: (1 in skills, students should be able to know a variety of cognitive and measuring instruments, measuring instruments commonly used to master the use of methods and maintenance methods, the correct selection and use of measuring instruments commonly used in the production site, to the general geometry and measurement and detection of typical parts, know how to care for measuring instruments, and the establishment of this awareness (2 in the knowledge level, requiring students to initially establish interchangeability of the basic concepts and understanding of well-known hole and shaft limit bias and coordination, shape and position tolerances and testing, surface roughness and testing, measurement techniques based on interchangeability of rolling bearings, keys and interchangeability with the detection cone interchangeability and testing gear interchangeability and measurement, interchangeability and thread detection, size chain knowledge, deepen understanding of the concept of interchangeability of basic, common understanding of geometric tolerances and with the Application (3 in the student's own learning process, students learn initiative, communication and interaction skills, teamwork and coordination capabilities, students can take the initiative to learn and think, can be found in the detection of problems through communication with others, to seek solutions to problems.

<<Interchangeability and Technical Measurement>> Curriculum design training programs
After a series of curriculum reform to explore, to build a "teaching, learning, doing" integrated teaching model. Theory of curriculum implementation in the professional knowledge to enable students to lay a solid foundation, try to guide students to think independently and to ask questions, apply their integrated knowledge to solve problems, develop the habit of independent thinking, not just relying on the limited common textbooks instill knowledge Practice is designed to carry out a series of specific measurements, in order to smoothly carry out training, designed to prepare teachers to hospital training instructions and training reports, the content shown in Table 1.

In the training process, the emphasis on mobilizing the initiative of students, so students switch roles from passive to active role and can apply the theoretical knowledge and measurement methods set the task to complete the project, the project encountered in the actual solution problem in the entire training process, teachers play a guiding role, the students for group discussions and put forward solutions to the problem complete the training program while training by completing reports and answering divergent questions, students can grasp a more flexible, the use of knowledge, to think about the relationship between professional knowledge through collaborative team of students and coordination ability and language ability to communicate.

Training project implementation
Based on the above ideas and design the content of curriculum, teachers do the appropriate preparation, the content of training courses to adjust the course schedule, class methods, so in the context of the setting to discuss the agreement, the implementation of the project training program Table 2.

Training effectiveness and project implementation problems
Results carried out from the course, the students of the physical, has great interest in measuring devices, measurements are happy hands, want greater autonomy, want their own ideas to solve the problem, learning efficiency and enthusiasm high the student to reflect this learning, the curriculum by doing good effect, to enhance their practical skills, to develop a way of thinking.

But in the course of the implementation process, there are also some problems: (1 student management is difficult, too many students, Classroom training is difficult to control. (2 instrument management is difficult, very curious students, to ensure the integrity of certain equipment The difficulty now is to take measures to operate training teachers to the students, there are strict requirements, each of the instruments used to inspect and make detailed records, so a great increase in the workload of teachers (3 teachers of the link between communication, progress, unity of teaching experiments have some difficulties.

Despite the difficult, but with the student exchange, the results were pretty good feeling, students have the initiative, there is great interest, willing to measure themselves, with their own ways of thinking to solve problems, improve learning passion, depicting increased their overall ability. In short, the <<interchangeability and techniques to measure the>> introduce this course pedagogy of teaching reform project of the initial exploration and practice, now it seems initial success.
