Research On The Construction Of Evaluation System Of Chemistry Classroom Teaching In Senior Middle School

Classroom teaching evaluation is an organic part of classroom teaching and an important part of the new curriculum reform.It is significant to improve teachers' overall teaching quality,students' learning efficiency and classroom teaching level.This research takes the chemistry classroom teaching evaluation of senior high school as the breakthrough point,and aiming at some problems existing in the current high school chemistry classroom teaching evaluation in our country: the evaluation of students is mainly about achievement,only paying attention to the absorption of students' knowledge,It neglects the cultivation of its emotional attitude and values,the singularity of the evaluation subject,the discrimination of the evaluation function and the backwardness of the evaluation idea.Based on the "three dimensional objective" in the curriculum standard,and from the point of view of the students' evaluation of the classroom,this paper constructs the classroom teaching evaluation scale of the common chemistry teaching types in senior high school,and forms the students as the main body of the evaluation.Moreover,the evaluation system of chemistry classroom teaching in senior high school pays attention to process evaluation.The evaluation system of chemistry classroom teaching in senior high school is studied by literature retrieval,field interview,questionnaire investigation,experimental method and statistical analysis.Literature retrieval is used to analyze the research results of classroom teaching evaluation at home and abroad,and a questionnaire survey is used to investigate the students' understanding of "three dimensional goals" and the degree of classroom participation.At the same time,the present situation of classroom teaching evaluation under the new curriculum standard is analyzed by using the method of teacher interview.Under the guidance of the theory of multiple intelligence,constructive,metacognitive theory and chemistry curriculum standards,the author integrates the five kinds of classes that often appear in high school chemistry classroom,according to the characteristics of each class.Construct different evaluation scales.The scientific and maneuverability of the evaluation system is studied empirically by the method of experiment.Finally,the SPSS19.0 software is used to test the data of the evaluation system by using the principle of educational statistics.The experimental results show that:(1)The application of the evaluation system can provide students with the direction of self-inquiry before class.According to the evaluation scale before class,the students have a certain understanding of what tasks should be completed and the degree to which they should complete each link of the class,and at the same time,the students' learning goals are more clear,and the important and difficult points are more prominent.(2)The application of the evaluation system enables students to monitor and test themselves effectively.The evaluation system can clearly tell the students the key concepts,knowledge and so on.The students can check themselves against the detailed contents of the evaluation system.(3)The application of the evaluation system provides a scaffold for students to integrate the contents of the class into the existing cognitive structure.In the evaluation system,students can clearly see the relationship between the classroom content and the existing concepts,thus it is easy to construct the relationship between concepts and improve the original cognitive structure.(4)The application of the evaluation system is helpful for teachers to understand the students' classroom mastery in time and make corresponding teaching adjustments.Students evaluate their classroom learning through the scale,and then feedback the results to the teachers.The teachers can judge the "distance" between their teaching activities and their goals,and find out the problems in teaching.These will directly affect the teacher's future teaching preparation,implementation and effect.In a word,the evaluation system of chemistry classroom teaching in senior high school can help students to master knowledge and test the effect of learning in high school chemistry classroom.This kind of evaluation model with students as the main body has good application effect.
