Test Analysis And Teaching Reflection Of Chemistry Electrochemical Part In Shannxi Province College Entrance Examinarion

Electrochemical module, one of the most important part in high school chemistry, occupies significant academic values. Ofen Important and diffucult question types presented in college entrance examinations, electrochemical questions were also an inevitable part in shaanxi province test. Since the implementation of new curriculum reform, great success has been made in innovation, integrity, difficulty and practice about electrochemical questions in shaanxi province examination.According to statistical results, students' main learning difficulties were summarized when they learned electrochemical knowledge. Mainly two aspects of subjective and objective were divided into, subjective aspect mainly including the effect of students' mind-set and the disability to analyze problems, Objective aspect was mainly affected by the intersection of knowledge and the difficultly. of the examination.After a overall detailed analysis of electrochemical test questions nearly six years in shaanxi province college entrance examination, it was found that type of choice was the most common form and a little was in the form of small questions. Basic scores were approximately possessed a stable value of 6-15 points. Examination content mainly including the working principle of thtere battery and electrolytic cell. In recent years, the secondary power supply and the fuel cells were hot and innovative topic, The investigated contents were mainly focuses on the total equation of battery, equation of electrode, electrode materials, judgment, writing, moving directions of ion electrode products and the change of solution pH, respectively. Subject were all classified medium-hard type, therefore, students need to strengthen training. This paper offers a reference and guidance for a glimmer of teachers and students to make directions more clearly.In the end, a profound reflection involveing teaching content, teaching process and teaching strategy has been made on electrochemical classroom teaching, It is necessary to strengthen the ability to basic knowledge and skills and pay more attention to the expansion of knowledge for teaching content. The multidimensional interaction and more encouragement should be implemented in the process of teaching. In order to improve the classroom teaching efficiency, reasonable teaching strategies could be selected, such as organizing small puzzle games, selecting better samples and establishing systematic solving and thinking methods.
