Research On The Strategy Of Preparation And Revision Of Chemistry Experiment In Senior Three Based On Core Literacy

Since the reform and opening up,my country's basic education has undergone several important reforms,and it has gone through three stages: from dual basics to three-dimensional goals and then to core literacy."Double base" refers to basic knowledge and basic skills,and "three-dimensional goal" refers to knowledge and skills,process and methods,emotional attitudes and values.The core literacy of the subject is a concentrated expression of the value of subject education,which is gradually formed by students through subject learning Correct values,essential character and key abilities.The basic education reform from double basics to three-dimensional goals to core literacy is gradually spiraling upward while meeting people's needs for education.The reform of basic education is a reflection on "what kind of people we are going to cultivate" and "what qualities and abilities do students need to survive,live and develop".Each stage has issued curriculum standards that meet the development requirements of this stage,and the curriculum standards at different stages have different requirements and evaluations for student development.Both "General High School Chemistry Curriculum Standards" and "Chinese College Entrance Examination Evaluation System" emphasize the importance of subject literacy and have certain requirements for subject literacy.Chemistry is an experiment-based science.Learning experimental knowledge can greatly promote the study and research of chemistry.In the teaching process in recent years,I discovered that the topic of chemistry experiment is more difficult for both the freshman students in high school or the second and third year students.Aiming at how to conduct the experiment teaching of chemistry in the third year of high school under the core literacy,this article explores the review preparation strategy for the experiment topic in the third stage of the experiment from the perspective of teacher "teaching".The author found that many students have memorized a lot of basic experimental knowledge by rote,but they have no wayto start when they encounter some innovative explorations and comprehensive experimental problems.This phenomenon is mainly aimed at this phenomenon.The author seriously reflects on the teaching in recent years,consults the literature,and researches for the past five years.The national exam papers for the college entrance examination questions summarize the implementation of the necessary knowledge and core literacy of the subjects examined in the college entrance examination questions.To study the connotation of the core literacy of the chemistry subject,on the basis of a deep understanding of the core literacy of the chemistry subject,listen to lectures and discuss,interview teachers and some students,and start from the textbook,summarize the high school chemistry compulsory one,compulsory two and elective four of the People's Education Press,Select some key experiments in the five textbooks,and give some reference to the teaching of key experiments.In the end,the author summarized some strategies for preparing for the exam preparation for chemistry experiments in the third stage: attach importance to textbook experiments,attach importance to the training of basic experiment operations,attach importance to the cultivation of experimental and exploratory thinking,let students participate in experimental design and evaluation,study the syllabus and curriculum standards,Research hot test sites to predict the direction of the test.At the same time,some suggestions are also given for high school chemistry experiment teaching.In teaching,we must not only teach students the necessary knowledge,but also cultivate students' key abilities,subject quality,and core values.The strategy put forward by this research is practiced in the actual teaching process of the author.During the communication with students before and after class,I learned that students are not worried about some basic experimental problems,and analyze their usual test scores and experimental questions.The score has also improved significantly.Therefore,the results of this study have a certain reference value for the review of senior chemistry experiment topics.
