Research On Chemistry Experiment Practice Teaching In High School Based On Cultivating Students' Scientific Inquiry Ability

The 2017 version of the curriculum standards has made clear the basic teaching concepts with chemistry subject literacy as the core,and it is an important task of chemistry teaching to cultivate students' chemistry subject core literacy,the chemical experiment teaching is the main way to cultivate and develop students' ability of scientific inquiry.This paper takes the effective implementation of scientific inquiry ability as the starting point,discusses the High School Chemistry Experiment Teaching Mode based on training students' scientific inquiry ability,and develops the case teaching,this paper summarizes the influence of experiment inquiry teaching on the cultivation and development of students' scientific inquiry ability,and provides some references for the cultivation and development of high school chemistry experiment teaching and scientific inquiry ability.Firstly,based on my own teaching experience and related literature reading,this paper summarizes the basic situation of chemistry experiment and scientific inquiry ability in senior high schools at home and abroad.This paper analyzes the first-level elements of scientific inquiry ability,and further determines the second-level elements of scientific inquiry ability in this study according to the level division of scientific inquiry ability in the 2017 version of the curriculum standard.On this basis,a questionnaire was developed to evaluate the ability of scientific inquiry of high school students.Secondly,on the basis of theoretical research and previous research,this paper discusses the high school chemistry experiment teaching mode based on cultivating students' ability of scientific inquiry,and designs the teaching and practice of experimental content.At last,the paper analyzes and summarizes the effect of practical teaching through question test,questionnaire survey and interview.The research shows that experimental inquiry teaching improves academic performance and arouses students' enthusiasm to participate in scientific inquiry activities.Experimental inquiry teaching effectively promotes the cultivation of students' ability of scientific inquiry,especially in the four dimensions of "the formulation of experimental scheme","the implementation of experiments","the analysis of phenomena and conclusions" and "communication and reflection".In experimental inquiry teaching,students make experimental plans and test theirfeasibility through hands-on operation,which exercises students' hands-on operation and thinking ability and deepens students' intuitive feelings towards abstract things.Cooperative inquiry strengthens students' ability of expression and communication.In the process of reflection and evaluation,students' questioning thinking is exercised,and their spirit and consciousness of scientific inquiry are accelerated.However,in the process of experimental inquiry,students' ability of "data collection","analyzing phenomena and drawing conclusions" and other dimensions is relatively weak.Students have a positive attitude towards experimental inquiry teaching;Although students' ability of scientific inquiry has been developed,the effect is not very obvious.In view of the above research results,this paper puts forward a teaching advice of chemistry experiment in high school based on cultivating students' ability of scientific inquiry: creating problem situation and stimulating the desire of inquiry.Create real problem situation,guide students to question and raise questions,stimulate students' desire to explore learning,and then develop students' scientific attitude of critical thinking;Pay attention to the process of inquiry and learn the method of inquiry.Teaching should emphasize students' process experience and real feelings,discover knowledge in solving problems,master the basic methods of scientific inquiry,and take the initiative to complete the meaning construction.Advocates cooperative learning and promotes expression and communication.Let students learn to express themselves and appreciate others in the "collective",and form a "learning community".
