Secondary Chemical Process Design And Evaluation Of Exploring Experimental Teaching

With the deepening of the modern vocational education reform and development of the vocational school education goal also in change is not only to cultivate primary practical technical talents is to cultivate more work in a line of high-quality workforce. Vocational school students is common to the academic starting point on the low side, chemistry course is health vocational schools all kinds of required main culture basic course for students. Health vocational school chemistry teacher, should according to the characteristics of students, subject characteristics, professional characteristics according to their aptitude.The traditional teaching experiment mainly validation experiments, its implicit knowledge mainly focuses on the experience knowledge represented by experimental phenomena and represented by the experiment principle of theoretical knowledge. However, the purpose of the experiment not only validation rules, training experiment skills, but to make students through the experiment in scientific study and research methods to obtain perceptual experience. From this point, the function of the traditional chemical experiment is relatively old and narrow, is not conducive to the cultivation of the modern secondary school chemical experiment teaching goal, is not conducive to training high skill talents conform to the requirements of The Times. The zetetic chemical experiment can effectively overcome the disadvantages of verification experiment, the function of experimental teaching should have adequately. Therefore, the reform of chemistry experiment teaching, it is imperative to advocate the zetetic chemical experiment. Should reflect the scientific understanding process, to strengthen the teaching of chemistry exploratory experiment, play to the subjectivity of the students, promote the students’personality development, implement diversified evaluation.On the secondary vocational schools to carry out exploratory chemistry experimental research, although is still in its infancy, but its theory, is more mature. From a practical point of view, however, is comparatively weak. This article is on the basis of practice, combined with the characteristics of the chemical experiment, draw lessons from domestic and foreign research progress about the experimental teaching of the main, the secondary chemistry zetetic experiment teaching make a preliminary discussion on the design and evaluation. In this paper, first of all, this paper expounds the necessity of reform of secondary vocational chemistry experiment, and through the analysis of the meaning and function of chemistry zetetic experiments, the definition of chemistry exploratory experiment. Then discussed the theoretical basis of chemistry exploratory experiment, content, design principle and its content design, teaching process design, evaluation design, finally, summarizes the teaching practice of chemistry exploratory experiment.The chemistry exploratory experiment is based on the theory of multiple intelligences. This is the focus of this article. Means that teachers should be abandoned in the process of teaching in teachers as the center, emphasis on knowledge,the students as the object of knowledge infusion of traditional teaching methods, adopting new teaching methods and teaching design thought. To design chemistry exploratory experiment, on the content design, want to combine teaching with contact life, pay attention to the ideas and outstanding problems. On the process of chemistry exploratory experiment teaching, this paper designed three stages:preparation stage, implementation stage, conclusion acquisition stage. Evaluation is essential in teaching a little ring, chemistry exploratory experiment teaching evaluation is different from the raditional teaching evaluation. It attaches great importance to the experimental results, and also attaches great importance to the experimental process; The evaluation subject from teachers to students; The content of the evaluation is not how much knowledge, but the spirit of the ability of autonomous learning and cooperative learning etc. Multiple intelligent evaluation standard; Using multivariate intelligent evaluation method and the mode of the ratings.Practice has proved that under the theoretical guidance, to construct chemistry exploratory experiments by the theory of multiple intelligences, and can effectively arouse the students’ learning enthusiasm, initiative and creativity, to cultivate students’ability of learning to learn, to improve their scientific literacy, so as to exert the whole course education function. Health vocational schools the zetetic experiments of chemical education is necessary, also is feasible.
