Based on the cultivation of innovative ability, we will carry out hierarchical experimental teaching. In the arrangement of experimental teaching content, the students' practical ability and innovation consciousness are also cultivated, and the students' knowledge level and individuality difference are also reflected. The experimental teaching content can be divided into basic experiment, comprehensive experiment and indexing experiment. The level will combine students' theory and practice, basic hands-on ability, scientific research and innovation ability as the starting point and destination of experimental teaching, and get rid of the old model of experimental teaching with the theoretical knowledge as the clue.
The basic experiment, that is, the principle, method, algorithm, application, etc. in the theoretical teaching of verification experiments, aims to master the experimental skills and deepen the understanding of the basic knowledge learned in the classroom. Through the experiment, students can evaluate the level of understanding and mastery of the staged knowledge. Such experiments often provide the purpose, requirements, experimental conditions, experimental principles, experimental procedures, experimental methods, and experimental results of the experiment. Students can perform the steps according to the contents of the experimental instructions, and then verify the experimental results. Correctness.
The comprehensive experiment is based on the basic knowledge, the relevant knowledge points of the comprehensive course, and the experiment with certain difficulty and complexity. The purpose is to reflect the internal interconnection between the knowledge points, which is an extension of the basic experiment. Evaluating students' ability to integrate knowledge and ability to analyze problems and solve problems often provides experimental purposes, requirements, experimental environments, and experimental principles. Students give experimental steps and experimental results.
The design experiment is a comprehensive knowledge of a course, a class of courses or a subject direction. It has comprehensive and developmental characteristics. It is used to evaluate students' comprehensive application level and development ability, and also makes students feel that learning is useful. Learn to use it. Such experiments often only provide experimental purposes and experimental requirements, and others are independently completed by the students, "eight immortals crossing the sea", each showing supernatural powers.
At present, in many experimental syllabuses of colleges and universities, three levels of experimental content have been set up more or less. On the surface, it has already reflected the level of teaching, but in fact it has not really been implemented. The content of the experiment is unreasonable. The comprehensive experiment and the design test are not obvious. The difficulty of the experiment does not meet the requirements of the course and the professional level of the teacher. On the other hand, the theoretical foundation of the student is not solid, and it is difficult to completely complete the comprehensive experiment and design experiment. Leading to the "downgrading" of comprehensive experiments and design experiments to basic experiments. In view of this, the experimental teaching functional departments are required to check the teaching links, carefully review the experimental syllabus, check the experimental teaching schedule, organize and manage the experimental process. Encourage and help students complete comprehensive and design experiments, allowing students to experience their own experimental results.
University laboratories are an important support for student training and scientific research. With the continuous expansion of the scale of colleges and universities and the number of enrolled students in recent years, the laboratory resources of colleges and universities are increasingly open, the number of personnel entering the laboratory and the mobility are increasing, and the limitations of experimental houses are The laboratory safety work is facing more and more problems, and the safety of the laboratory is becoming more and more prominent. How to improve the safety of the laboratory has become an urgent problem for every university.
1 Significance of conducting safety training
1.1 Lack of safety skills education is the main cause of major accidents and casualties In recent years, laboratory safety accidents have occurred, bringing great property losses and many casualties to colleges and universities. Analysis of the causes of college safety accidents, we do not Difficult to find: laboratory safety accidents have hardware construction problems, but also software construction reasons, prominent in the safety system is not perfect, security awareness is weak, security technology is lacking, and emergency measures are not effective. After specifically analyzing the major safety accidents that cause serious property damage and casualties, we will be distressed to find that if each accident occurs, the correct treatment, correct rescue measures and personnel escape methods can be adopted. The damage caused by the accident can be reduced to a small extent. Therefore, in the safety management of laboratories, safety skills education and training should be placed in a more prominent position.
1.2 Safety Production Skills Definition Safety production skills refer to the skills and abilities of people to safely complete their work. It includes work skills, proficiency in the skills of the work safety device, and the ability to properly handle it in an emergency situation .
1.3 The necessity of safety skills education The training of safety skills is the training of the practical work ability of the practitioners. Laboratory safety requires not only safety knowledge, but also the necessary safety practices. Safety knowledge education only solves the problem of “should know”, while skill education focuses on “should be met” to meet the requirements of “giving it to fish” as we usually say. This kind of "capability" education can avoid and reduce the occurrence of laboratory accidents, and it is likely to reduce the loss of property and personnel caused by accidents.
1.4 Safety Skills Education Targets Teachers and students are the main participants in the laboratory of the university. The laboratory teachers are the main managers and participants of the laboratory safety work. Their quality conditions, whether they have knowledge of safety and environmental protection, and the importance of safety work. Directly or indirectly affect the level of laboratory safety management.
