Research On Teaching Mode Of Chemistry Experiment In High School Based On Innovation Literacy

In contemporary world,creativity,which is the most powerful force,promotes social and economic development.How to cultivate the innovative talents has become the survival of a nation.In recent years,the research,which is based on innovation literacy,has become a popular issue in the field of education.How to improve students' innovation literacy level,discussing the cultivation path of innovation literacy is the key.Chemical experiment is an important carrier for cultivating students' innovative accomplishment.Therefore,it is of far-reaching significance to explore how to develop students' innovative literacy by using high school chemistry experiments.There are two common ways to cultivate innovative literacy: one is to set up special experiment courses or experiment series,so as to specifically cultivate innovative literacy;The other one,reforming the teaching content and mode to infiltrate the cultivation of innovative capacity,this study belongs to the latter.In this study,according to the classification of high school experiments in experimental Chemistry,an elective course of high school chemistry in Jiangsu Education Edition,and aiming at the three dimensions of innovative literacy,some types and contents of chemical experiments were selectively selected and rearranged,and the modified PBL teaching mode was adopted to cultivate innovative literacy.Based on literature analysis,this study defined concepts such as innovation literacy,teaching model and PBL,explained the importance and necessity of cultivating students' innovation literacy through the process of chemical experiment inquiry,and discussed the applicability of PBL teaching method to promote the development of innovation literacy in experimental teaching.On this basis,it summarizes the elements and framework of students' innovative accomplishment.Aiming at the development of innovation literacy,the PBL based chemical experiment teaching model process framework was constructed,namely "project introduction ——project conception —— project practice ——project evaluation".From the teaching materials in the experiment to select the material separation and purification experiment(extract iodine in kelp),material inspection and identification experiment(scientific use of 84 disinfectant),electrochemical problem inquiry experiment(homemade drive small fan ideal battery)and material preparation and synthesis experiment(acetylene preparation and properties of test)four types of experiment,design based on PBL teaching plan,Taking two classes of students from Q Middle School in Qinzhou City,Guangxi Zhuang Autonomous Region as the research object,and aiming at cultivating students' innovative qualities,the practical research on the teaching mode of chemistry experiment in high school is carried out.Finally,the students' innovation literacy level was measured by using the student selfevaluation scale,teacher observation scale and student mutual evaluation scale,and the teachers' and students' evaluation of the teaching mode was understood by using the interview method,so as to evaluate the high school chemistry experiment teaching mode based on the cultivation of innovation literacy from different angles.The results show that the teaching mode of this study can enhance the capacity of innovation;The experimental class students have been remarkably enhanced in the subelements of of innovative thinking,such as divergent thinking,convergence thinking and recombination thinking and in the sub-elements of innovation practice,the ability of planning and design,the ability of cooperation and coordination and the ability of hands-on.Therefore,the mode of the study can enhance the development of students' innovative accomplishment.This study explored the operational mode of developing students' innovation literacy based on chemical experiments,and provided a reference scheme for the effective cultivation of innovation literacy.In addition,this study further enriched the research on the ways and methods of chemical experiment teaching,and laid a foundation for promoting the effective development of chemical experiment teaching.
