Research On Teaching Strategies Of High School Chemistry Experiments Under The Background Of New Curriculum

On September 3rd,2014,the State Council issued Opinions on the Implementation of the Examination and Admissions System,which officially launched a new round of college entrance examination reform.The college entrance examination points have been gradually promoted throughout the country.This reform has made great changes in high school textbooks,curriculum standards and evaluation methods.For chemistry subject,it is a natural science which based on experiments,and experimental teaching is the focus of this reform.Based on the background of the new curriculum,this research focuses on the analysis of the impact of the new curriculum reform on chemistry experimental teaching in high school,proposes chemistry experimental teaching strategies that conform to the reform trend,and strives to effectively improve the efficiency and quality of chemistry experimental teaching,aiming at providing some references and ideas for those frontline chemistry teachers in senior high schools,which also makes some preliminary explorations in the implementation of the new curriculum reform in chemical experimental teaching.This article first analyzes the changes in the content of chemistry experiments in senior high schools under the background of the new curriculum,which also highlights the characteristics,curriculum requirements and the status of experimental teaching.Secondly,the following five experimental teaching strategies are proposed:(1)in the formulation of experimental teaching objectives,deeply understand the connotation of core literacy and scientifically setting experimental teaching objectives;(2)in the creation of experimental teaching environments,the development of real problem situation materials promotes the transformation of students 'learning methods;(3)for the key points of the content of experimental teaching,focusing on the curriculum standards and experimental prototypes,and improve students' knowledge transfer ability;(4)carefully design experiments and inquiry activities to cultivate students' higher-order thinking ability;(5)on the evaluation of experimental teaching effects,implement the integration of teaching,learning and evaluation,and carry out experimental daily learning evaluation.Then apply the chemical experimental teaching strategy proposed in this article to the experimental teaching design of Converting Chemical Energy into Electrical Energy —— Primary Battery,and set up experimental classes and control classes for teaching practice through educational experiment method,and by the questionnaire survey,interviews,written tests and other methods to test the effectiveness of the strategy.Finally,the analysis and survey data confirm that the high school chemistry experimental teaching strategy can guide teaching in the background of the new curriculum,achieves the higher goals,better classroom satisfaction,higher teaching efficiency and quality,and has advantages in the construction of chemistry subject knowledge.
