Keywords: vocational, fine chemical production processes, integration and reconstruction, project-based teaching

Courses constitute the core elements of training model, and curriculum reform, innovative training model is the core of concern. Our traditional curriculum to the professional curriculum as the main concern is to build students' knowledge structure, emphasizing the knowledge of their own integrity, systematic, although the curriculum will help teachers organize the teaching and student mastery of subject knowledge, but the lack of direct contact with the work, is not conducive to the students and work process knowledge of technical mastery, and these two types of knowledge is often The core content of Vocational Education.

Project Approach is a typical professional tasks rely on constructivist learning content, which requires teachers in teaching activities according to occupational status of knowledge and skill requirements, from the typical professional tasks in the rational design of teaching programs, students in the teacher's guide the actual work process under the full program, complete the teaching project. this process, the students through the "learning to do" and "doing", can be general to understand the potential occupational status of the main tasks, and to the overall of work situations to recognize their competent work, and understand and master the technical knowledge required courses and job skills, access to analyze and solve problems.

<<Vocational fine chemical production processes>> course is a core of specialized courses, which is characterized by the implementation of the project decided to help students get more teaching positions corresponding professional competence and professionalism of students to cultivate.

Clear <<vocational fine chemical production processes>> Teaching objectives
Vocational Education and training objectives is "to train production, construction, management and service needs of first-line advanced Technology-based expertise," this talent between skilled and between the academic type, with a certain degree of theoretical knowledge, skills, structure places mental skills, creative skills-based, its theory and Technology to master the Technology, rather than experience and Technology.

Therefore, the <<vocational fine chemical production processes>> should be demand-oriented teaching, in curriculum, teaching content, teaching methods, and follow "to apply for the purpose, with the necessary and sufficient for the degree" of teaching principle, a student-based, so that students have the ability to apply chemical technology for the chemical Industry demands for qualified personnel to enable them to better compete in the market. a specific curriculum objectives are divided into the following areas.

Ability to target through this course, students can choose a typical fine chemical synthesis routes, will analyze the typical production of fine chemicals, raw materials and products used in the indicator, can read and draw a typical fine chemical production flow chart, able to correctly analyze a typical fine chemical production factors, according to the typical reaction of fine chemicals production characteristics of selected reactor, and to operate its production process and control, product standardization can be familiar with technology, the production of accident analysis and processing, can be found in the production process of insecurity, and environmental pollution problems, familiar with fine chemical products commonly used in some of the common test equipment to analyze and apply complex technology to fine chemicals with the formula to work through the kinds of media resources to find the Information that can self-learn new knowledge, new technology, with product development capabilities, can work independently or in collaboration group plan and implement, can actively search for scientific methods to analyze and solve problems.

Knowledge and understanding of the typical target the nature of fine chemicals, use, production and packaging and storage products, fine chemicals, to master the typical purification of raw materials and production with the use of catalysts, to master the production of fine chemicals typical reaction principle and the production process factors affecting the familiar typical production process of fine chemicals, fine chemicals production are familiar with the typical equipment of the structure and characteristics of a typical fine chemicals to master standards-based technology products; familiar with the process of production process organization, safety and environmental protection issues, familiar with fine small chemical product formulations.

Quality objectives through the implementation of project tasks, develop students entrepreneurial spirit, teamwork, communication skills, sense of responsibility, professional ethics, professional standards and overall quality.

Fine chemical production processes vocational curriculum design
This course during development, the first for the positions of relevant chemical research, access to job tasks, and then invite Industry experts held technical and business seminars, joint analysis of job requirements, establish professional competence and work process status, and to summarize positions typical tasks, and the production line and technical personnel together to develop curriculum standards and build a closer and ability to meet the needs of the practical application of skills training systems, and finally, for the actual work done during the various tasks should have the professional capacity, the typical tasks into learning tasks, the design of learning programs, outstanding students around the establishment of professional ability and professionalism to develop the main line to form an integrated theory and practice for the construction of curriculum reform ideas.

Content of fine chemical process involving a variety of teaching fine chemicals production, reactor and process, which is characterized by many kinds of fine chemical products, recipes and ingredients, involving more than the basics, covering more than academic knowledge. Given the large knowledge systems, how the characteristics of fine chemicals and professional training objectives, combined with the characteristics of our school in the place and development needs, the limited teaching hours, so that both the choice of teaching content focus, but also enable students in the fine chemical Industry have a certain breadth of knowledge, and ability to understand the area and some of the latest developments in research, teaching is a fine chemical process of the key issues.

Fine chemical production processes vocational curriculum integration and reconstruction
Age group to follow this course, practical, and the principle of local characteristics, the use of project teaching the original <<Fine Chemical Technology>> Course and <<Fine Chemicals comprehensive experimental>> curriculum was integrated. The past is to teach complete technology courses, and then on the courses, this traditional mode of teaching theory, light practice, teaching theory, teaching planning time first, teaching the theory and practice of teaching independently, this teaching method can not meet the modern high-skill training practical talents need the project of teaching the theory and practice of teaching can make a good convergence theory can be applied to maximize the guidance and practice to help students go fight in training, full technical students comprehensive ability and professional skills for students after graduation in fine chemical production and development of new varieties to lay the necessary theoretical and technical basis.

Production of fine chemicals raw materials to prepare experienced, chemical reaction, product processing and comprehensive utilization of waste treatment process and the typical real tasks as a teaching vehicle, and in accordance with the laws and the ability to form cognitive characteristics of 10 study programs designed , respectively, surfactants, adhesives, coatings, food additives, feed additives, synthetic materials, additives, pesticides, detergents, cosmetics, flavors and fragrances, to build a systematic work process based on the <<vocational fine chemicals production process>> project-oriented courses (see Figure 1.

Curriculum, the teacher can analyze project requirements, the mission statement issued to the students according to each type of fine chemicals in a typical product, a project designed several tasks in order to paint the study, for example, the assignment is as follows.

Task One: Oil-degree red alkyd paint production. Task Two: amino alkyd enamel production. Task Three: the production of epoxy novolac. Task 4: white thermosetting acrylic baking finish production. Task Five : the production of vinyl acetate emulsion. Task 6: Polyurethane emulsion coatings.

(5 alkyd resin production equipment are familiar with the structure and characteristics. (6) master degree of Oil red alkyd paint formulations (7 familiar with the paint process. (8 understand alkyd paint alkyd resin production and preparation process safety and environmental issues.

Fine chemical production processes of vocational courses to implement the teaching methods of teaching
Teaching the use of Information for each project, planning, decision-making, implementation, inspection and evaluation of six-step teaching.

Information the students according to mission requirements, to find relevant Information independently, and the point of self-learning knowledge, students in the learning process if you have questions, you can ask the teacher.

3071 plans to fine chemical classes, for example, the class 40 students were divided into 10 groups of four, after consultation within the group to discuss the Information received, considering various factors, develop a preliminary work plan.

Making preliminary plans developed by students in group discussions, teachers review, that the scientific and can be implemented, then the plans. Decision-making through the implementation of the plan in accordance with, the group is expected to complete work tasks, each team randomly selected one person for public defense. Here we must note that, due to the dangerous goods involved in the chemical Industry and more serious environmental pollution, harsh operating conditions, not may, as some professionals in the school building as a large number of training base, in addition, fine chemical technology confidentiality and also determines the monopoly in the school-enterprise cooperation, the plant is limited to allow students to visit the type of internship. Therefore in the implementation stage necessary to take a variety of ways to accomplish tasks, such as the use of internal and external training base of training methods, use of corporate law to visit the factory, the use of laboratory experiment, the simulation software, simulation method, etc. In short, students are asked not only to use collected information, write a project report to deal with teachers, such as degree of red alkyd paint Petroleum production method to take a factory tour and laboratory methods are two ways to complete.

Check this link to be turned over to the student learning outcomes, including project reports, products in kind. Through student self-examination, peer review, the teacher checks to see completion of the task.

Evaluation evaluation criteria are divided into three parts, one professional competence, including specialized data access conditions and information processing capabilities, the abilities of the implementation phase, the project completion report and of the rational, PPT production and reporting capabilities, knowledge assessment (through paper forms ; Second, social skills, including attitude, unity and collaboration, communication and presentation skills, third, innovation, ability to work in the discovery of new problems, and propose new ways to work creatively. This assessment is not only the learning outcomes for students static evaluation, but also dynamic evaluation of the learning process, this dynamic evaluation is given the task of starting from the student teachers from time to time to master. Finally, reviews by teachers to help students complete the task summed up the process and methods, identify deficiencies and improvement measures, to learn the knowledge and skills within, along to group and individual scoring.

Through the Jilin Institute of Fine Chemical Industry and Technology 3061 and 3071 to implement two classes, "fine chemical production processes vocational" courses teaching experiments show that the project, the implementation of the project-based teaching, the most active students increased significantly, students work on the technical knowledge and process knowledge to grasp the situation well.

In the <<vocational fine chemical production processes>> the project of teaching the course, the typical production of fine chemical products as the starting point for students to develop professional competence and professionalism to develop the main line to the work process-oriented, with typical job task analysis, based on real production process as a carrier to school part-time teachers, teachers and business-led, student-centered, in accordance with professional jobs and professional capacity-building requirements, so that students professional competence, methods, capabilities and social skills been improved, but also to stimulate the students interest in learning our teaching program group in the future work, will continue to explore the fine chemical production processes based on the work process of curriculum development and application.
