On the Teaching Concept of Higher Vocational Education in the Information Age

Paper Keywords Higher Vocational Computer Teaching Mode

Higher vocational education is an effective way to solve China's employment problem and improve social productivity. Traditional educational methods can no longer meet the needs of the information age. This paper describes some problems existing in higher vocational education, expounds the transformation of education from theory-practice-theory to practice-theory-practice, and puts forward a new concept of applying computer software technology to higher vocational education in view of the rapid development of computer technology.

1 Problems in teaching

Modern teaching has made great progress compared with the previous ones, but we find that the working ability of current higher vocational graduates is greatly reduced compared with the previous graduates, and few people can be independent, which shows that education in China is still derailed from society.

1. 1 theory-practice-theory teaching mode. In the process of teaching and educating people, teachers have played a great role. Whether a course can really be taught to apply what you have learned is a test for teachers. Now, most teachers in our higher vocational colleges are still continuing the consistent teaching method, that is, theory-practice-theory. Usually, the education of engineering is to talk about the theory first, then arrange the corresponding practice class after learning the theoretical knowledge, and finally take the theoretical examination. Students first accept the concept of dryness. Taking mechanical design as an example, we should learn mechanical parts. In the past, teachers used to draw parts on the blackboard to explain. Now we have ppt, which is more intuitive for students to learn, or teachers will bring objects to the classroom to show them, making it easier for students to learn. But with such abstract knowledge, students will feel abrupt. Students who are not sensitive to machinery are even more confused. This makes it impossible to use theoretical knowledge well in the follow-up practice, which leads to half the effort in theoretical teaching.

1.2 attaches importance to theory and ignores practical training. This teaching tendency pays attention to the integrity of the theoretical system, basically adopts the textbooks of ordinary colleges and universities, and spends most of the time on theoretical teaching. Another reason for this tendency is that many vocational colleges recruit a large number of newly graduated students to teach. These people are highly educated and theoretical. In order to give full play to their own advantages, they are bound to be unable to understand the characteristics of vocational education and lay particular stress on theory. Due to the uneven quality level of higher vocational education, it is impossible to teach thoroughly in some colleges, and the training opportunities are reduced. Moreover, training is often only carried out in a simulated environment, and students lack sufficient training and feelings in combining theory with concrete practice. As a result, students have limited theoretical knowledge and average practical ability, and become ordinary people who can't reach high or low.

1.3 pays more attention to practical training than theory. This tendency is to emphasize practical ability, and theoretical teaching is based on sufficient foundation. This tendency emphasizes and values practical training, while theoretical teaching is relatively simple. In order to be full, some courses that will help students enhance their innovation ability in the future have been cut. This tendency is more and more obvious, and the students we train are not just simple operators. This enables students to cope with their current jobs, but they have no stamina.

2 thinking of teaching philosophy

2. 1 Make the theory completely practical. Higher vocational education is in great demand for training applied technical and technical talents. Therefore, higher vocational education should integrate the curriculum and teaching content across disciplines according to the needs of cultivating professional ability and the requirements of various positions in actual production and operation, that is, change the current learning first in the teaching process? What is this? , study again? Why? Professional teaching should not start from theory, but should be completed according to such a process: practice (understanding the actual professional activities)? Theoretical teaching? Comprehensive practice (application ability training)? Innovation and the cultivation of thinking ability. Specifically, it includes the following links:

2. 1. 1 Let students work in the corresponding major for a period of time, without putting forward professional requirements for students, and observe more than participate. The purpose is to let students understand and feel the professional characteristics, work content and ability requirements of this major, and understand the current ability gap and the professional knowledge that needs to be mastered. This process should not be too short. Students should be given enough time to feel, have a clear overall understanding of their future career, post, history, present situation and development of work content, understand what knowledge and skills they need to master in order to engage in this work, and figure out why they should learn and what they should learn.

The first round of theoretical teaching 2. 1.2. In this link, relevant theoretical teaching contents can be arranged interdisciplinary according to the post ability requirements. Because students already have perceptual knowledge, at this stage, the teaching of professional theoretical knowledge accounts for the main part, and the training time can be shorter. In the school training room, the progress of theoretical teaching is carried out on a case-by-case basis.

The second round of training 2. 1.3. In this training stage, students are required to be employees in real professional positions. A good evaluation method can inspire students to see through what needs to be improved, think about how to improve, deeply understand the relationship between theory and practice, and raise theoretical understanding to a new level. This link should be carried out in the enterprise with sufficient time, and it should be a complete business cycle or process, so that students can have full experience and feelings, and it is also convenient for assessment.

The second round of theoretical teaching 2. 1.4. At this stage, students should have a sublimation in theory on the basis of completing the above three links. Mainly in the form of various special courses, big case teaching should occupy a key position, encourage and guide students to make full preparations for taking the title examination. The purpose is to further cultivate students' comprehensive professional ability and innovative thinking ability, so that students can further their studies.

In this way, students learn while doing, from practice to theory, and then from theory to practice, using their brains and hands, emphasizing the discipline of professional quality in the whole teaching process, and the teaching effect is self-evident. Among them, the key to the implementation effect lies in the design of the teaching scheme of the above links.

2.2 Abstraction into concreteness. Some courses belong to professional basic courses, and because of the characteristics of the courses themselves, they do not have the conditions to practice first, such as mechanical drawing. Mechanical Drawing is a compulsory professional basic course in higher vocational colleges. The purpose of teaching is to cultivate students' drawing and reading ability. The difficulty of teaching is to cultivate students' spatial ability and spatial imagination. The teaching idea is to first talk about the principle of point, line and plane projection, then talk about the three views of basic body, and finally talk about the three views of parts. The study of mechanical drawing directly affects the study of subsequent specialized courses. This kind of teaching thinking increases the learning difficulty of students. It is difficult for students to fully understand things that are too abstract, and the whole teaching process cannot be separated from graphic display. At present, the commonly used teaching mode is to help students establish the concept of space with static wall charts and slides, old and difficult-to-carry physical teaching AIDS. There are some shortcomings. Wall charts, slides and models can only reflect the results, but cannot express the formation and change. Teachers must accurately, vividly and vividly describe and repeat. Even so, it is difficult to achieve better teaching results. It also increases the difficulty for teachers to teach.

Today, with the rapid development of computer technology, if computer technology is applied to teaching, it will make abstraction concrete and make students easy to learn. In view of students' proficiency in computers, it is not difficult to learn software. It is easy to learn Solidworks 3D software before learning mechanical drawing. Students only need to learn some drawing commands and 3D and 2D conversion commands, which can be completed in a few class hours. After completing this part of the teaching, go to learn three views. In learning, the combination of three-dimensional and three-dimensional views in Solidworks can enhance students' thinking ability in images through repeated three-dimensional and two-dimensional transformations.

2.3 Simplify the complex. In colleges and universities, many courses are very principled and theoretical, such as mechanics of materials. Material mechanics is a basic course for engineering students, in which the stress and strain distribution of components under load has always been the focus and difficulty of teaching. If the relationship between load and component stress distribution can be vividly displayed to students, it will certainly deepen students' understanding and mastery of relevant knowledge and achieve twice the result with half the effort. In order to achieve good teaching effect, ready-made three-dimensional design software is used. Using the COSMOSXpress function provided by SolidWorks, the stress distribution of components under load can be easily analyzed and the corresponding analysis diagram can be generated. This function has the advantages of simple operation, accurate analysis and clear drawing, which can be used as a reference for the teaching of material mechanics. Using COSMOS and Xpress to complete the analysis requires the following five steps: (1) building an equivalent component model; (2) Define the material of the component model; (3) determining the constraint position; (4) adde corresponding load; (5) Analyze the components and check the analysis results. If necessary, the results can also be displayed in the form of animation.

SolidWorks software can completely satisfy the virtuality of various stress and strain conditions in material mechanics. Nowadays, multimedia teaching methods have been widely used in higher vocational education. As long as you are good at learning and using for reference, many abstract and complicated theoretical knowledge in engineering teaching can be concretized and visualized, thus effectively promoting teaching and improving teaching effect.

All education is trying to pass on knowledge to students. The temporality and professionalism of higher vocational education require teachers to master correct teaching concepts and methods. Regardless of the dual system, integration of theory and practice and situational teaching advocated now, the most important thing is the teaching process. If every teacher can explore effective teaching methods in his own curriculum, China's vocational education will expect faster development.
