Research and Practice of Training Modern Packaging Talents (II)

3 Innovative practice of teaching content and teaching methods

3.1 Integrating scientific research and teaching reform into classroom teaching In terms of teaching content, our university has always attached importance to the integration of scientific research and teaching reform into classroom teaching. For example, in the teaching of “packaging structure design”, a series of new packaging theories enrich the teaching materials and teaching content.
a. The packaging structure is placed under the “human-package-product-environment” system for research. In a large system, the packaging should be “people-oriented” and “environment-friendly”. In the subsystem, the packaging design resides in packaging. The dominant position of the project, packaging structure in the packaging design of the basic position. From the point of view of packaging design as a system, a new concept of "three-three" principle of paper packaging design, and "ideal size ratio" and "best size ratio" are proposed;
b. It proposes to divide the folding carton into four types according to its forming method, namely tubular box, disc box, tube disc type box and non-tube non disc type box, and organize teaching materials and teaching according to this classification;
c. The study summarized the structure and molding characteristics of the back wall, the self-locking wall lining and the non-disc type wallpaper box, summarized the design skills of mxn (P-type, Q-type) wallpaper boxes, and introduced The more complex mixnj (combination of P, Q mixes and different sizes of interior contents) design enriches the teaching content.
d. An in-depth study of the Carey-Kart formula was made to propose the Karibart constant for multi-wall corrugated board and the international standard unit constant.
3.2 Constantly updating and revising teaching content In the teaching process, we constantly raise and study new issues, and we dare to deny our own opinions. Negative is progress.
In the forthcoming national "Tenth Five-Year Plan" textbook "Packaging Structure Design (Second Edition)", we have revised some of the original views. The content of these amendments is due to the continuous emergence of new structures, or It is a new breakthrough in the way of thinking, or a new spark among teachers and students in the exchanges inside and outside class. The revised content will not only improve the original theoretical basis, but may also give rise to new ideas.
The preconditions of the original self-locking bottom design were negated, and it was recognized that as long as the working line design is reasonable, any tube box can be designed with a self-locking bottom. At the same time, the work line was further studied, some box structures were modified, and some new box types were designed. The box type designed according to the principle of the working line can be adapted to automatic forming and automatic packaging.
The definition of non-tube non-disc cassettes was revised, and the non-disc non-disc type was proposed to be characterized by relative displacement rather than positive-reverse forming. The original concept of positive-to-rectangular molding was adapted to all the partition boxes. From this point of view, a systematic study was conducted on the partition boxes.
3.3 Innovative Education in Classroom Teaching Our school integrates innovative ideas into classroom teaching to develop students' innovative potential.
The understanding of innovation education should not be limited to the creation of one or two theoretical courses to conduct the teaching on paper, but should incorporate innovative ideas into teaching content, develop students' innovative ability in a subtle manner, and tell students that any structure is It is a product of scientific and technological advancement. It will inevitably leave behind the mark of the times. Historical limitations can be found. Therefore, it is necessary to critically examine them with critical eyes, correct defects, and correct defects, and it is possible to design an innovative structure. As long as the practice of practice is enhanced, there will be more imitations, more designs, more thinking and more innovation. By combining knowledge learning, ability development and quality improvement, a combination of theoretical and practical learning methods fosters the ability to ask questions, analyze problems and solve problems, and in particular foster hands-on and innovation capabilities.
For example, when explaining a non-standard carton, analyze the advantages and disadvantages of the 0201, WA, N-WA, and F-WA boxes, and find out the basis for the successful innovation of the F-WA box. As shown in Figure 1.

Another example is the teaching of non-tube non-disc folding cartons, starting with the basic 1 x 2 partitions, and gradually speaking to the complex m×2. m includes two series of odd and even numbers, and different series take different design methods. as shown in picture 2.
3.4 Carry out "research", "heuristic" teaching, and reform of teaching methods.
The "16th" Congress proposed to construct a system of lifelong education. In fact, it requires teachers not only to impart knowledge, but also to teach learning methods.
Conduct research teaching, raise questions in the classroom, organize students to think, and absorb students' fresh ideas.
Focusing on heuristic teaching, increase the use of methods of induction, analysis, and synthesis. Pay attention to cultivating students' self-learning abilities, analyzing problems and problem solving skills and hands-on skills. Pay attention to selected contents for students of different majors and different levels. In accordance with their aptitude.
3.5 Actively develop CAI courseware and implement multi-media teaching Our school packaging engineering teachers actively develop CAI courseware, and modernize teaching methods as an important content of teaching reform. Some CAI courseware can be animated. It not only improves the teaching effect but also improves students’ interest in learning and understanding.

4 Educational reform results

a. While carrying out research projects of the Ministry of Education, our school also actively organizes teachers to conduct research on various types of education reform projects at all levels. At present, there are 4 municipal education reform projects under study;
b. Actively carrying out teaching materials construction, since the establishment of the major, we have jointly edited 13 teaching materials and monographs, some of which are common in the national packaging colleges, and the “Packaging and Testing Technology” has won the award for excellent teaching materials at the ministerial level, and “Packaging Structure Design” has been awarded the Tianjin Municipal Level. Teaching achievement award;
c. Due to the solid foundation of students and the strong ability to innovate, they are generally praised by employers. The employment rate of graduates for three consecutive years ranks among the top ranks of our school. This year, a total of 18 students in our college took graduate students, and two of them obtained Nankai University’s corporate management and In the legal profession, one took a degree in industrial design from South China University of Technology, and another three students obtained dual bachelor degrees in our school.

5 Conclusion

Through the research and practice of training modern packaging talents, we have profoundly realized that "innovation is the soul of a nation's progress and the inexhaustible driving force for a nation's prosperity". The packaging education should firmly establish the concept of “quality education, lifelong education, and innovative education” and realize the transition from “specialists to generalists, teaching to education, teaching to learning”, training a large number of specialized talents and top-notch innovations for packaging and related industries. Talent.
