From the Foreign Packaging Engineering Experimental Teaching

Experimental teaching is an important way to cultivate students' innovative ability. However, there are still many places in traditional experimental teaching that are incompatible with the innovation education. The author intends to give an example of a foreign packaging engineering school's teaching curriculum setting for analysis and comparison: they are quite different from experimental teaching. Pay attention. In the teaching schedule, the first-year experimental class accounted for 20% of the total teaching hours; the second academic year increased to 30%; in the third year of the factory internship stage, still maintain about 15% of experimental teaching classes. This is a far cry from the experimental course arrangement of our engineering department. Still taking the packaging engineering teaching in our country as an example, according to incomplete statistics, the general experimental class only accounts for about 10% of the total class schedule. Although various institutions or disciplines are not the same, this relationship is a matter of improving the quality of students and nurturing practical talents. It cannot but attract people's attention. This requires that we must strengthen the reform of experimental teaching, and innovate experimental teaching from the aspects of educational concepts, teaching content, teaching methods, and assessment mechanisms, so as to explore a new path for innovative education through experimental teaching.

Experimental Teaching is the Basis of Cultivating Students' Creative Ability

The laboratories of institutions of higher learning are set up and served to match multiple discipline groups. Such as light industry, textiles, packaging and packaging engineering related to machinery, automation, structural design and processing and manufacturing. At the same time, there are also vast areas of contact and collaboration for production companies and research machinery outside the colleges.

The experimental teaching and practice link of colleges and universities is the most vivid and crucial link in cultivating students' innovative spirit and innovative ability. Its advantage lies in enabling students to combine the theory and practice they have learned, and focus on the cultivation of students' knowledge and the use of knowledge and innovation. It has both the inheritance of knowledge and hands-on practice. Its main education follows the rules of human understanding. , To discover and recognize scientific theories in scientific experiments, and to test the practical teaching of the theory obtained in scientific experiments. It has intuitive, practical, comprehensive, innovative and other educational features.

Experimental capabilities include basic experimental capabilities and creative experimental capabilities. The former refers to basic experimental capability operations, and the latter refers to the ability of scientific and technological innovation and development established in practical experience based on the former. Without a solid basic experimental ability, it is impossible to discover creative experimental capabilities. Therefore, innovation ability is a creative experimental ability in basic experimental ability. Their success is all achieved in the laboratory. The development of modern science and technology, especially the emergence of a large number of cross-disciplinary and marginal disciplines, further demonstrates the importance of solid experimental capabilities in scientific development and innovation.

Experimental teaching is the main method for colleges and universities to cultivate students' experimental ability. It has the irreplaceable role of theoretical teaching in cultivating students' innovative ability. First of all, it shows that the experimental teaching has cultivated students' basic ability to observe, analyze and solve problems, and has cultivated interest and laid a foundation for exploring innovation. Followed by comprehensive experiments and design experiments in experimental teaching, to guide and motivate students through their own unremitting efforts and practice, and to achieve their own will to temper and creative ability to play the joy, to strongly stimulate the desire to innovate and cultivate the students Creative thinking. Only by scientifically developing creative thinking on this basis can we create talents with creative abilities.

How to Cultivate Students' Creative Ability in Experimental Teaching

The reform of experimental teaching lies in the innovation of educational ideas and ideas. The current misunderstandings in education are mainly reflected in: (1) The importance of experimental teaching to the cultivation of innovative talents is insufficient. In college teaching, long-term attention has been paid to the teaching and examination of curriculum theory and knowledge points, and the cultivation of experimental teaching and experimental abilities has been neglected. This has led to the lack of students’ ability to observe, analyze and solve problems, and lacks the potential for innovation. (2) The experimental teaching model is outdated. In teaching methods, indoctrination methods, spoon-feeding methods, and closed-type teaching methods account for the majority of students. The students only completed the experimental report “by the paintings and scoops”, which seriously hampered the cultivation of students’ innovative ability. (3) Insufficient attention was paid to the construction of laboratories, and the experimental equipment was outdated, and the management personnel were seriously lacking.

To fully correct this misunderstanding, we must have a comprehensive change and innovative understanding of the concept of experimental teaching, and truly put experimental teaching in the new layout of modern engineering teaching.

Student-centered experimental teaching is a way to cultivate students’ creative thinking and ability

(1) Prepare experimental teaching content meticulously and scientifically. The selection of experimental content should be based on the basic principles of strengthening basic skills, highlighting comprehensive design, and fostering innovation. In terms of basic skills, it is necessary to emphasize the content that must be mastered, but also to design experimental content at different levels according to students’ abilities, interests and specialties, and to guide students who have spare capacity and have aspiration in the experiment to higher requirements and Difficult to enter, let it self play and stand out. In the aspect of comprehensive design, according to modern advanced technology and curriculum setting, some comprehensive design topics with strong comprehensiveness, high practicability and wide creation space are arranged to cultivate and enlighten students' innovative thinking.

(2) Innovative student-centered experimental teaching methods. In the experimental class, teachers try to talk less about the experimental process, operation methods, and matters needing attention. The teacher only strengthens the inspection and guidance in the experimental class, letting the students to carry out their own experiments, and the whole process of the experiment is to find problems in the students. , asking questions and solving problems, the effect of the experiment seems to be not good, but both teachers and students feel a reward, teachers can find differences in the ability of different students, easy to teach students in accordance with their aptitude. At the same time, the students through their own efforts and the teacher's instructions to complete the experiment, impressive, really learned from the experimental process of knowledge, training ability. In addition, the writing of experimental reports shifted from focusing on experimental results to attaching importance to experimental discussions. Highlight the opinions of the report with outstanding opinions and look for information to strive for action.

(3) Carry out a variety of extracurricular science and technology activities to create opportunities and conditions for students' creativity. Can make full use of laboratory resources to develop students' knowledge and guidance, develop students' innovative ability, guide students to analyze certain devices and experimental methods in teaching materials, identify their shortcomings and shortcomings, and then carry out experimental improvement and innovation. Students' enthusiasm for participating in this activity is very high. High, some students even spent the rest of the day in the laboratory, there are many experiments to improve success. We absorb some students and teachers to engage in scientific research, so that students can voluntarily sign up to participate in teachers’ research projects according to their hobbies and expertise, and provide them with an open, independent, inspiring and innovative science and technology experimental environment. It can be conducted in cross-departmental laboratories so that students can participate in real scientific research and development under the direct guidance of teachers in the undergraduate study. Practice has proved that all students who participate in extracurricular science and technology activities have been well-trained in their hands-on and creative abilities, and the quality of their thesis has been significantly improved.

Build a new assessment mechanism around measurement of innovation capabilities

As an important part of experimental teaching, assessment should play an active role in improving students' innovative ability. The new assessment mechanism must focus a series of learning activities on students to innovation, and gradually establish a new assessment mechanism that promotes the cultivation of students' innovative ability.

(1) The contents of the experimental assessment. The content of the experimental assessment should shift from basic knowledge measurement and basic skills to ability measurement. The assessment of basic knowledge and basic skills runs through the assessment of competence. The assessment focuses on students' ability to use basic knowledge and basic skills to solve practical problems.

(2) The method of experimental assessment. As an independent experimental course, the method of experimental assessment should be used in various ways. It should combine written examinations, oral examinations, and operation assessments, and increase the proportion of operation assessment. In written examinations, it is necessary to increase the proportion of subjective test questions, reduce the proportion of objectivity test questions, and highlight the ability to analyze student's analysis, strain, and comprehensive ability.

The world of the 21st century belongs to the age of knowledge economy. Science and technology are advancing by leaps and bounds. Talents and knowledge will occupy a more important position. How higher education can train high-quality talents for the knowledge economy through teaching reforms is a new topic that is being explored. We believe that Through constant exploration, summarization and practice, it will surely be able to take on the historic mission given in the new century.
