Study On The Influence Of "Cooperative And Inquiry-based" Experimental Teaching On Chemistry Learning Effect Of Senior High School Students

With the formal promulgation of Chemistry Curriculum Standards for General High School(2017 edition,2020 revision),the focus of educators is senior high school chemistry core literacy,and the primary task of senior high school chemistry teaching is to cultivate and improve the comprehensive quality of students."Cooperation and inquiry-based" is a new learning mode in which group members learn by themselves,discuss and communicate through cooperation between teachers and students,and acquire knowledge,skills,attitudes and values by means of operation and exploration,because it can effectively improve the comprehensive quality of students received more and more attention.Chemistry is an experiment-based discipline,experimental teaching of chemistry is an important way to improve students’ core literacy of chemistry.Therefore,the integration of "cooperative and inquiry-based" learning into experimental teaching is consistent with the requirements of the new curriculum reform,which can improve students’ chemistry learning effect,cultivate students’ scientific inquiry ability and innovation consciousness,develop students’ core literacy of chemistry.And it is of great significance.In June 2022,the author selected some senior one students from H and G middle schools in Chongqing as investigation objects to investigate the application status of "cooperative and inquiry-based" experimental teaching in senior one chemistry teaching,And select chemistry teachers of different ages from different schools to interview the current implementation of "cooperative and inquiry-based" experimental teaching of chemistry in senior high school as well as their views and suggestions on that.According to the survey results,senior one students had strong interest in chemical experiments,strong desire for exploration and strong sense of cooperation,but weak ability of cooperative exploration.In addition,the "cooperative and inquiry-based" experimental teaching of chemistry in senior high school is less carried out and needs to be further strengthened.Therefore,the author designs the chemical experiment in compulsory Course I of Human Education Edition(2019 edition),and carry out "cooperative and inquiry-based" experimental teaching in senior one,which can satisfy students’ desire for inquiry,and the overall learning effect of students,improve the status quo of "cooperative and inquiry-based" experimental teaching.Four teaching cases: "Exploring the influencing factors of the preparation of ferric hydroxide","Exploring the mystery of the reaction between sodium and water","Exploring the mystery of the ‘Su sisters’ " and " Exploring the mutual conversion of ferric salt and ferrite " was designed in this study.In September 2022,two parallel classes in senior one of G Middle School in Chongqing was selected for teaching practice for one semester.Before practicing,the chemistry and chemistry experiment scores of the two classes were analyzed,and it was found that there was no significant difference between the two classes.After practicing,Through students’ evaluation and teacher interview of the experimental class,it was found that students’ interest in chemistry learning and willingness to cooperate have significantly improved.Through the paired sample T test of chemistry learning internal motivation of students in experimental class,it was found that students’ internal motivation had also been significantly improved.By comparing the chemistry and chemistry experiment scores of the experimental class and the control class,it was found that there was a significant difference.The causes of the influence of cooperative "cooperative and inquiry-based" experimental teaching on the learning effect of senior one students was further analyzed by the author.By interviewing students with different levels of internal motivation,it was found that the higher the internal motivation of students,the higher the interest in learning and cooperative exploration consciousness of students,and better the learning attitude;Through the regression analysis between chemistry scores and internal motivation,it was found that internal motivation has a significant positive influence on academic achievement.Based on this,it can be concluded that the main reason for the positive influence of "cooperative and inquiry-based" experimental teaching on the learning effect of senior high school students is the improvement of students’ internal motivation.Research conclusions:(1)Carrying out "cooperative and inquiry-based" experimental teaching,it can positively influence the chemistry learning effect of senior high school students.(2)The internal motivation of senior high school students to learn chemistry can be improved by carrying out "cooperative and inquiry-based" experimental teaching.(3)"Cooperative and inquiry-based" experiment teaching promotes the improvement of students’ internal motivation,which is the main reason for the improvement of students’ chemistry learning effect.The innovation of this research is reflected in the following aspects:(1)Cooperative learning and inquiry learning are applied to experimental teaching at the same time,giving full play to the synergistic effect of the two learning styles.(2)Developed a case of "cooperative and inquiry-based" experiment teaching suitable for senior one students for peer reference.(3)It further analyzes the causes of the influence of "cooperative and inquiry-based" experimental teaching on chemistry learning effect of senior high school students,and make clear the relationship among "cooperative and inquiry-based" experimental teaching,internal motivation and learning effect.(4)Teaching practice are used to verify the research results of this paper,which improves the credibility of the conclusions and expands the research depth of "cooperative and inquiry-based" experiment teaching...
