Exploration And Practice Of High School Chemistry Life-oriented Teaching Based On Core Literacy

To meet the requirements of talents training for the new era,the new curriculum reform puts forward the idea of attaching importance to the cultivation of students’ core literacy.It is clearly required that teaching should be based on students’ interests and experiences and should pay attention to the connection between knowledge and life,and classroom teaching should focus on students’ "autonomy,cooperation and exploration".Under the requirements of talent training,the life-oriented teaching should use many ways to let the study return to the life and improve the students’ core literacy.First of all,this paper uses document analysis method to summarize the development of life-oriented teaching,analyses the domestic and international research status,to have a deep understanding of life-oriented teaching model and core literacy.According to the characteristics of lifeoriented teaching model,this paper creates teaching cases from the aspects of environmental protection problems around students,interesting experiments upgraded fromteaching materials experiment,social practice close to production,family healthy life experiment and so on.Secondly,through questionnaire survey,this paper is here to have a understanding of the current situation of life-oriented teaching in the No.1Senior High School in Lishu County,and to analyze the students’ interest and needs in chemistry teaching.Teachers there pay attention to the combination of life cases and knowledge,the guidance of students.However,there are still some problems such as the lack of students’ experiments and social practice activities.On this basis,this paper uses real cases to make up for the problems in the above-mentioned teaching practice.Thirdly,on the basis of understanding the needs of students’ interest,the teaching practice research is carried out.The teaching content comes from the the key chapter of the college entrance examination such as the material and its change,the important non-metallic element in the chemical production,the chemical reaction and the energy as well as the basic nutrition.To cultivate students’ abilities of "macro-identification and micro-analysis","change idea and balance thought","scientific spirit and social responsibility","evidence reasoning and model understanding" and "experimental exploration and innovation consciousness" by analyzing the structure and experimental phenomena,combining the students’ experiments and life cases.Through the results of practice,this paper analyzes the improvement of students’ chemical core literacy,and the problem whether it can solve the problems of students’ experiment and lack of social practice activities.Finally,through the data of questionnaire(post-test)and the comparison of the results between the experimental class and the control class,this paper concluded that while improving the performance of students’,the lifeoriented teaching can also promote the cultivation of students’ learning ability,application-transfer,self-study and exploration-practice ability,which proved the important role of the life-oriented teaching in the cultivation of students’ core literacy,and at the end of this paper,the deficiency and prospect of this research are analyzed.
