On exploration and practice of case teaching

Abstract: We introduce the safety case method training, which would be true to actual work scenarios to typification process, the formation of reflection and analysis for the case of students, through independent research and mutual discussions, students analyze problems and to improve problem-solving abilities.

First, the case method's advantages
1, practical. Petrochemical business is high-risk industries, safety is a prerequisite for the development of enterprises, employee safety training should focus on to enhance the safe operation of skill-based, for example, for the prevention of hazardous chemicals, fire, through a combination of materials in our theory expounded by the cracking of the factory took place in winter carbon four tank fire analysis and discussion of this typical case, to achieve the following teaching objectives: ⑴ four carbon copies of the winter dehydration operation should pay attention to what, ⑵ for containing succinic en storage and transportation of materials in the production process of how to properly operate, ⑶ the relevant safety regulations which are so in case teaching, the practice is very conducive to student ability.

2, to stimulate the students interest in learning, training of dangerous chemicals from the production of the selected cases the actual work, convincing strong. Some cases directly from the students about, and then analyzed and discussed, we take the initiative to explore solutions to the problem, active classroom atmosphere in the case teaching process, student interest in learning and be excited to a higher level of theoretical knowledge is conducive to learning and understanding the same time, students are lead by the passive acceptance of knowledge into the past to accept and to actively take the initiative to explore, easy cases revealed students master the relevant issues, through careful thought, to propose solutions.

3, help to improve the overall level of teachers, first teachers have to collect, collate appropriate case, the case involved in the relevant knowledge should be a more profound understanding. Aforementioned cases, the teachers in the knowledge of fire prevention, cracking Winter storage of carbon four comprehensive understanding of operating outside the law, while the carbon four production storage conditions, the nature of butadiene, also have to have a more profound understanding. Secondly, in the actual teaching process, teachers must seize the opportunity to organize coordinate Finally, teachers should also have a strong comprehensive capacity, so as to end of the discussion in the case study summary and review.

Second, the case method the general steps
1, to prepare the case through years of practice and exploration, we believe that the choice of cases, both typical and also close to the actual production. So we often go to the production line to collect material, constantly updated cases in the case of teaching, students are lead teachers will be prepared in case of pre-class students informed, so that students understand the contents of the case and requires students to find the necessary information, speak well prepared.

2, to explain to discuss the case. To discuss the case is the case the central part of the teaching process, teachers should try to mobilize the initiative of students, guide students to discuss the case closely around, the whole class together to discuss ways can also be divided into group discussions in hazardous chemical safety training, we use modern teaching methods, simulation of the accident, causing the students are vivid, and thus greatly improve the effectiveness of teaching.

3, summarizes the case in the case of participants to analyze, discuss, draw conclusions, the teacher should be summarized, to make just the right evaluation. The main problem for the case to make emphasis, so that students deepen their knowledge and point to grasp. discussion is not deep enough for the students, not the exact place, do highlight the same time teachers should also highlight, through case analysis and discussion, students should learn what kind of lessons learned.

Third, the teaching notes
1, choose the high quality of teaching needs cases. First, the case must be true and accurate and representative. Petrochemical enterprises are people with every accident case in exchange for blood or life, safety training is a valuable asset, and therefore fully use of some typical cases with industry analysis to explain the accident, so that we truly understand that "every order into a blood-stained, and then the blood can not be verified," the deeper meaning. The second is to focus on practical cases. selected cases to work with students reality, through case studies, practical help to improve students' practical skills. Third, the comprehensive principle should consciously choose a certain degree of difficulty of some accident cases, to stimulate student in-depth research and careful analysis and evaluation, facilitate these difficulties and to understand and grasp the key issues to achieve better teaching results.

2, to in-depth and thorough case studies Case teaching is important that through the analysis of the case, so that students improve skills, specifically for a similar operation, how to master the correct way to prevent accidents, so case studies can not just stop at the surface in-depth and thorough analysis is essential.

Fourth, the effect of case method
1, improving the students analyze and solve problems. Dangerous chemicals will be applied to the case method of teaching the process of training, the purpose is to promote students to use their learned knowledge, through in-depth and detailed analysis to solve practical work problems. Students can give full play to their talents, combined with actual work, find out the answer as they see fit. precisely because of this feature of the case method, so it can encourage students to conduct a comprehensive analysis and continuously improve the analysis and solving problems.

2, improving the students practical skills is most characteristic of case teaching students to work close to the actual and enhance the attractiveness of teaching and the interaction force, prompting students to apply what they have learned comprehensive initiative to identify problems, analyze and solve problems so that students will be learned quickly into application capabilities. specific issues, to identify the risks, and to control risk in order to avoid possible accidents.

3, improve the comprehensive capacity of teachers to Case Teaching the teachers put forward higher requirements, teachers must thoroughly understand the focus of the case involved issues, but must also grasp the issues involved in a series of theoretical basis, and thus concluded that end of the discussion in the full case summary and review.

Case study with its closely linked with the actual, operable features were in hazardous chemical safety training, set up a bridge between theory and practice. After years of exploration and practice to achieve good results, which will be safe technical training trends.
