Study On Strengthening The Evaluation Of Oral Examination In The Chemistry Teaching Of Middle Schools

After a new round of curriculum reform,the evaluation of chemistry learning in compulsory education stage has been extended from the past only focusing on cognitive evaluation to the comprehensive evaluation of students,and the diversification of evaluation methods has been emphasized.Therefore,because of the difficulty of evaluating the two hidden goals of "process and method" and "emotion attitude and values",the single paper pen test can't meet the requirements of the new curriculum reform.In view of this,this paper is taking the evaluation of "process and method" and " emotional attitude and values" as the core of the research work in the Chemistry Teaching of middle schools,strengthen the evaluation of oral examination in the chemistry teaching of middle schools,in order to promote students' language ability,improve the thinking ability of chemistry and form positive learning emotion.The thesis consists of 5 parts.The first part is the background,significance,content and method of the subject research.Through the literature,based on the understanding of domestic and international research on the reform and innovation of the oral evaluation,expounds the practical significance of strengthening the evaluation of oral examination in the chemistry teaching of middle schools,briefly introduced the research contents,methods and steps.The second part is mainly surveys the teaching evaluation methods of chemistry in middle school from two different perspectives.One is a questionnaire to understand the chemistry learning evaluation of all the students at grade 2014 in the fuhe branch of Chengdu railway middle school.Another one is an interview with experts and front-line teachers.The three is to organize the "oral examination can effectively eliminate cheating in the exam" discussion.Through the investigation,we can find out the real idea of students' learning evaluation and the necessity of introducing new evaluation methods in the chemistry teaching of middle schools,so asto carry out the experiment research in a targeted way.Through discussion,it is affirmed that oral examination plays a positive role in eliminating the misconduct of exam.The third part is the empirical research on strengthening the evaluation of oral examination.This part takes the fuhe branch of Chengdu railway middle school in early 2014 class 4and class 6 students as the research object,mainly expounds the preparation before the experiment from three aspects: the determination of the oral examination concerns,the formulation of the oral evaluation criteria and the setting of the test questions.This paper introduces the preparation before implementation,and introduces the process of improving the experiment implementation plan.In view of the lack of speech and speech in the experimental class,this paper summarizes the pertinent teaching strategies,and applies teaching strategies in the fuhe branch of Chengdu railway middle school grade2014 students.The fourth part is mainly based on statistical experimental data,comparative analysis of the four changes which include students' learning emotion and learning attitude,Language expression ability and chemical thinking process,learning methods before and after the experiment,so as to draw experimental conclusions.The fifth part is mainly about reflection and outlook.The conclusion of this study shows that chemical oral examination can effectively improve the chemistry quality of middle school students.It is meaningful to strengthen the evaluation of oral examination in the chemistry teaching of middle schools.Although the evaluation of oral examination has many difficulties in operation,it can effectively eliminate cheating in exams and can not be replaced by other evaluation methods.Hope that more Chemical counterparts can pay attention to oral assessment in teaching,and make more research and practice in this field,and constantly improve the application of oral assessment in the chemistry teaching of middle schools.
