Investigation And Research On Current Situation Of County High School Chemistry Experiment Teaching In Henan Province

In the 2017 edition of the chemistry curriculum standards,the Ministry of Education put forward the teaching objectives of the core literacy of chemistry disciplines for the purpose of quality education.This requires teachers to fully understand the core literacy,and to understand and innovate the teaching methods based on the core literacy of students.The “Knowledge Center” turned to the “Capacity Center”.Anchored instruction is based on real and infectious events or problems.It is a teaching method that emphasizes the concept of “student main body”.It is in line with the requirement that the education reform be changed from “teacher center” to “student center”,which is conducive to cultivating students' core accomplishment.The core literacy of this paper is to cultivate the core literacy of middle school students,and use the anchored instruction mode to design teaching cases.The main work is as follows:1.Using literature research,questionnaires,interviews and other methods to discuss the background and research status of core literacy;to investigate the understanding of the core literacy concepts of chemistry subjects and the targeted cultivation of students' core literacy,online survey The first-line teachers of 200 middle schools in the Central Plains area,statistics show.56.76% of teachers have a general understanding of core literacy,and 24.24% of high school first-line chemistry teachers have been consciously cultivating students' core literacy of chemistry;but 3.03% of teachers said they don't understand core literacy.No contact,9.09% of the teachers said that they never considered the core literacy of students in teaching,and did not deliberately consider or choose reasonable teaching methods and models.2.The core literacy concept and its connotation are investigated and analyzed.The data shows that 51.67% of the teachers believe that the core of core literacy should be the most important and most important ability for students' lifelong development;17.28% of teachers believe that the "core" of core literacy refers to several important qualities that are conducive to lifelong development;65.64% of teachers believe that scientific thinking ability plays a key role in the lifelong development of high school students;78.79% of parents in the survey pointed out that Scientific thinking ability will play a key role in the future development of the child,so the scientific thinking ability is the most critical ability for the lifelong development of high school students.3.The discussion analyzes the core concepts of middle school chemistry core literacy and the specific methods of cultivating scientific thinking ability,aiming at improving students' core literacy,and discussing the basis,method and implementation strategies of anchored instruction mode in high school chemistry teaching and specific links.Choosing the PEP version of the high school chemistry must be a "separation and purification of matter","quantity of matter-Moore" and "enriched in the elements of seawater-chlorine",using the anchored instruction model to design teaching cases.4.Select the experimental class and the control class to carry out comparative experiments.According to the psychological and mental characteristics of high school students,the scientific thinking ability is divided into three levels: analytical problem ability,knowledge transfer ability and logical thinking ability.The evaluation of scientific thinking ability is designed.Evaluation scales at various levels;use behavioral quasi-experimental research methods to observe and test students' class attendance,and collect data through after-school interviews,mid-term and final-term score tests.The first factor excellent rate and the second factor excellent rate of the problem analysis ability of the experimental class and the control class were 40.2%,42.5%,36.3%,and 31.5%,respectively,The experimental class was significantly higher than the control class;The excellent rate of knowledge transfer ability of the experimental class and the control class were 34.3%,38.9%,40.1%,40.6% and 32.2%,34.7%,37.6% and 39.2%,respectively.The experimental class also showed a significant improvement over the control class;In the two grades at the end of the period,the average score of the experimental class exceeded the control class.After the difference analysis,the difference of the true level of the two classes in the period was not significant(P > 0.05);in the final grade,Z=2.02(02.02 > 1.96),Significant differences in the overall level of the experimental and control classes(0.01 < p < 0.05).The data results show that the anchored instruction mode is conducive to improving students' scientific thinking ability and cultivating students' core literacy on the basis of ensuring students' stable performance.
