Studies On Combined Evaluation In Collegial Chemical Experiment

Education evaluation research is one of the three greatest realms of the education science research with education basic theory research and education development research. Education evaluation has abundant function in the education activity, and become a necessary main factor in the education activity. The writer discovers a lot of problems in the evaluation of the chemistry experiment, while engaged in the teaching chemistry experiment. For this, the writer made a questionnaire to parts of students in Jilin University at the end of 2006 found that there are a lot of problems in the chemistry experiment evaluation. After analyzed the result of the investigation, writer combined current evaluation trend to develop a set of university chemistry experiment mode, in order to improve the university experiment evaluation and make the evaluation offer a better service for the experiment teaching.At the beginning of the research, we did a review for the education evaluation and student evaluation. The thesis makes the education evaluation and student evaluation tow definitions clear, namely: education evaluation means a scientific process of judging various education activity, education process and education result that under the guide of a certain education value, by the determinate goal of the education using a certain technique method. The study evaluation means a kind of worth judgment which takes the students as the evaluate object using a certain technique according to a certain standard. In the meantime, we looked back the evolution of the education evaluation, namely the three different histories period of ancient traditional examination,modern times science examination and the contemporary evaluation. And then we also elaborate the development and characteristics of each period evaluation and stress introduced the famous "eight years study " in the development history of evaluation. Immediately, we compartmentalize the type of the student evaluation: according the different function of student the evaluation in the teaching activity, we divided three types that are the student evaluation for examine evaluation, the development evaluation and summary. From of dissimilarity, The student evaluation can be divided into opposite evaluation,absolute evaluation and individual evaluation according to the different value evaluation standard. According to the different contents of the evaluation, it can be divided into the student's studies evaluation and the student's moral qualities evaluation. According to different evaluation purpose, the student evaluation can be divided into the selection evaluation,qualified evaluation and the development evaluation. Then we emphasized the function of evaluation such as management function,examine function,leading function and development function etc.,and make clear the purpose and the meaning of the evaluation. Finally, we discussed the contemporary student evaluation theory and development trend, namely: we initiate to set up evaluation system which takes the development as core. It also is a development evaluation. We instant the quantity evaluation mode of the quality evaluation mode; and emphasize the reliability and scenario of measure and evaluation, it also is the request for the true evaluation. We should encourage a student take part in the evaluation, namely a student participate the evaluation, and attach importance to the thinking process , suggest the process evaluation.In the second part of the thesis, we analyzed and explained the related problems of the university chemistry experiment though the feedback information .There are three aspects related problem in the university chemistry experiment: The first, the students didn't believe the result of the experiment evaluation, and thought that the results ware unilateral and subjective. The second, the evaluation is difficult for the teachers. The third, the application of the evaluation is not enough. According to above-mentioned problems, we analysis the two angles from the characteristics of the experiments and evaluation oneself and evaluated perfect. On the analytical foundation, we did a related request to the evaluation of the university chemistry experiment, and hope to design a new evaluation mode to resolve the problems existed in the current evaluation. According to this request, we put forward the compound evaluation mode of the university chemistry experiment, and it's three points, namely: the compound of the learning process and the evaluation process, the compound of the teacher evaluation and students'evaluation and the compound of the quality evaluates and quantity evaluation. In the third part of the thesis, we discussed the contents and the movements of the university chemistry compound evaluation systematically and completely. Because of the process of the university chemistry compound evaluation top evaluation, our research divided the university chemistry compound evaluation into preview evaluation,practice evaluation and summarize evaluation . In the traditional teaching and the study activity, the preview evaluation is usually neglected. Although teachers and students have certain understanding about the effect and importance, the evaluation is almost a blank in this realm. We analyzed the problem in preview from the chemistry t contents. Namely: no pertinency, no deepness, comprehends of the experiment lack incorporate and organic. On the basic, we think the need to be evaluated, and discuss the related affairs of the preview evaluation, namely: the evaluators of the preview evaluation are teachers and students, the evaluation of the contents should be the contents of the experiment and it's blue print, and also discussed the evaluation standard and the expression of evaluation result. During the evaluation practice stage, we inquired the main factor of the practice stage evaluation first, namely: the experience result, the fulfillment degree of the experiment operation, experiment of attitude, feedback of experiment and the innovation in the experiment. We analyzed the problems exist in the evaluation of practice stage in talking foundation of the main factors of the experiment evaluation, and art the same time, we contraposed the existent problem, put forward the a series of reform target, include: evaluator,the evaluation standard and the method of choice , the express of evaluation result and it's application etc. It elaborated a new conceive of the university chemistry experiment evaluation systematically, which is the university chemistry compound evaluation mode. During the period of the summary of evaluation, we understood the request to the evaluation contents and the evaluation result. On this foundation, we discussed and analyzed the problems of summary evaluation in the chemistry experiment currently. And we did related provision towards evaluator, evaluate standard, choose method etc on the foundation of analyses. In the aspects of evaluator, we encourage students to participate actively, and complete the evaluation mission with teachers together. In the meantime we can make more people take part in the evaluation with the modern information technique; in the aspects of evaluate standard, we established three standards: teacher impression evaluation, student's comprehensive evaluation by oneself, evaluation given by the classmates. In the aspect of method choosing, we adopt the way that the quality and quantity turn to combine together, given the students the true evaluation.The university chemistry experiment compound evaluation is according to the evaluation development trend, put forward some new ideas that aims at the related problem in the university chemistry evaluation, and it is development evaluation of more dimensions. The university chemistry experiment compound evaluation takes student as origin, takes development as a purpose. We expect it can play an important role in the student's chemistry experiment.
