Research On The Teaching Of Chemical Experiment In Senior High School Based On Flipped Classroom

In 2017 th edition of "The Ordinary High School Chemistry Curriculum Standard",experiment teaching was paid more attention.And it pointed out that teachers should help the students master the basic experimental methods and skills,and to experience the basic process of experiment exploring,and to develop the skills of the students to solve comprehensive practical problem.Flipped class model combined learning before class and teaching in class,could help students complete experiment foundation knowledge before class to help the students finish learning of basic experiment knowledge before class and cause the deep thinking of the students of the experiment.Then they could carry out high quality study of experiments in class learning,fully realizing the value of the chemistry experiment teaching.Based on the recent research situation of flipped class model,constructivism learning theory,learning effect pyramid theory and the STS education theory were chose to rely on,and classification of chemical experiment basing on cognitive goal of skills was chose as well.According to characteristics of different types of experiments,high school chemical experiment teaching strategies based on flipped class model were put forward.Specific cases were designed,and two classes with equal grades were chose as the control groups,and the practical research was carried out.By means of quantitative research and qualitative research,the teaching effect of the proposed strategies and the attitude of the students were evaluated by the following test questions and questionnaires.The study showed that the chemical experiment teaching strategies based on flipped class model followed the cognitive regularity of students,and could give full play to the advantages of "blended learning" mode--"self learning before class + in class teaching".The application of the proposed teaching strategies could create more opportunities for students to consolidate their operation skills,experience the exploration process and stimulate innovative thinking.In the course of teaching,we focused on cultivating comprehensive ability of students all the time.
