With the proposal of "Made in China 2025", the intelligent manufacturing industry is constantly upgrading and innovating. Intelligent production modes such as intelligent workshop, intelligent factory and intelligent detection are constantly emerging, and emerging technologies and new jobs are emerging in an endless stream. As a quality assurance method for industrial development, NDT technology is developing towards the direction of intelligence, high precision, high efficiency and modularization, and has become an important support and guarantee means for the development of intelligent manufacturing industry.
The National Vocational Education Reform Implementation Plan issued by The State Council in 2019 clearly states that vocational education and general education are two different types of education with equal importance. Today, with the rapid development of high-end equipment manufacturing industry, higher vocational education has trained a large number of high-quality technical personnel for China.
Shaanxi institute of defense industry professional technology institute of intelligent manufacturing of mechanical product testing technology (hereinafter referred to as the inspection professional) positive docking key technique of the detection in intelligent manufacturing industry, following the NDT industry development, update the professional post skills, adopt integration "in + out" theory and practice of teaching methods, "the school full-time + adjunct" teaching team, Actively practicing the reform of the three education, promoting the reform of "nondestructive testing" course teaching, effectively supporting the new demand for testing professional personnel training, and providing talent support for the development of intelligent manufacturing industry.
Analysis on teaching problems of "Nondestructive testing" course
The teaching content
Due to the nature of the course and the limitation of class hours, what students learn from books is only theoretical knowledge, there is no skill training. This leads to the lack of knowledge and skills of students. It can be seen that the current teaching situation of "nondestructive testing" course is not only difficult to support the talent training needs of testing specialty, but also fails to consider the adaptability of vocational education development, that is, it fails to strictly standard the laws and requirements of vocational education.
Practical conditions
Contrast "NDT" curriculum knowledge and skill, the school did not establish a nondestructive testing training center, but in the testing professional training room, on the basis of precision measuring scattered acquisition and radiographic testing, ultrasonic testing, eddy current testing and other related technical training equipment, and has no skill points against curricula, and to develop advanced practice testing project, only courses in a test, The content is relatively simple, the training skills are not clear, and there is a lack of professional and systematic "NDT" course practice teaching platform for teachers and students to "learn".
Course team and teaching methods
The curriculum team of the school only has teachers of specialized courses in the school, but no part-time teachers from enterprises, and no specialized information database of part-time teachers has been established, which brings great inconvenience to the off-campus practical training of later courses. The teaching method is traditional classroom teaching and experimental practice, which leads to low learning interest of students and poor teaching effect. Moreover, the school does not provide an off-campus training environment, which is not conducive to the accumulation of post experience and the formation of school-enterprise co-education and co-management talent training mechanism.
In order to adapt to the adjustment of the industrial structure of intelligent manufacturing and the industry's new demand for testing talents, form a better professional structure and optimize the training of talents, the university has decided to carry out the teaching reform of "nondestructive testing".
The reforms
There are 2 small classes in each grade of testing major. Since the curriculum reform of Testing major was implemented in 2018, the testing class 3181, as a pilot class, has performed well in curriculum assessment, vocational qualification examination, skill competition and other projects. The comparison of data between pilot class and non-pilot class is shown in the following table.
Number of course examinations passed | The number of vocational qualification certificates obtained | The number of winners of the school skills competition | ||
detection3181 | 34 | 11 | 13 | 39 |
detection3182 | 21 | 2 | 4 | 40 |
In addition, in terms of the actual teaching situation, students in the pilot class show a strong interest in learning, the depth of understanding of knowledge points and skilled degree of skill points are obviously higher than those in the non-pilot class. As can be seen from the above table, with the continuous deepening of the curriculum reform of "NDT", students' engineering practical ability and employment competitiveness have been significantly improved, and they have demonstrated their skilled professional skills.
The detection major takes moral cultivation as the fundamental task, strengthens the students' professional competence and sustainable development ability as the goal, strengthens the students' engineering practice ability and labor consciousness cultivation, promotes the integration of talent cultivation with industrial demand, the course content ADAPTS to technological development, and the teaching process matches the production process. The strategy of jointly developing curriculum content, jointly implementing professional teaching and student management, and jointly carrying out teaching evaluation should be carried out by the school and enterprise, so as to reconstruct teaching contents, teaching methods, academic evaluation and other talent cultivation elements, and strengthen students' professional skills and professional qualities.
conclusion
With the upgrading of intelligent manufacturing industry, the demand for high-quality technical personnel of modern NDT is expanding. As the highland of technical personnel training, the educational reform of vocational colleges is imperative. Shaanxi National Defense Industry Vocational and Technical College keeps up with the technological change of intelligent manufacturing industry, focuses on the trend and requirements of professional personnel training, implements the curriculum reform of "nondestructive testing" for testing specialty, puts forward specific reform strategies and requirements, and carries out pilot work. Practice has proved that advanced teaching content and teaching methods provide an effective way for students to cultivate their skills. This curriculum reform can provide example and reference for vocational education curriculum reform.
