Application And Practice Of Task Card Teaching Mode In Chemistry Experiment Teaching In Senior High School

Chemistry is a natural science based on experiment.Therefore,experimental teaching plays an irreplaceable role in chemistry teaching.The main purpose of this study is to explore how to apply the task card teaching mode in the teaching of high school chemistry experiment,so as to improve the quality of chemical experiment teaching effectively.Based on core literacy of high school chemistry,constructivism learning theory,humanistic learning theory and zone of proximal development theory,this study creatively combined with the characteristics of chemical experiment teaching,constructed the task card teaching mode of high school chemistry experiment teaching,and designed three high school compulsory part of the experimental teaching cases according to the five basic links of task card teaching mode,which were applied in teaching practice in order to test the effectiveness of the teaching mode.This study mainly includes the following five parts:The first part: from the requirements of the new curriculum reform and high school chemistry curriculum standards for high school chemistry teaching,as well as the problems existing in the current chemical experiment teaching in China,it's stated that the improvement of chemical experiment teaching mode is imperative.By analyzing and summarizing the research status of this teaching mode at home and abroad,it's showed that the application of task card teaching mode in high school chemical experiment teaching is meaningful and feasible.The second part: the design principles of task card teaching,the operational framework and basic links of task card teaching mode and the theoretical basis of task card teaching mode are specifically analyzed.Theoretically,the task card teaching mode conforms to the requirements of new curriculum reform objectives and high school chemistry curriculum standards,and meets the requirements of chemical experiment teaching.The third part: after designing the evaluation tools and analyzing the feasibility,the task card teaching mode is designed and applied.The teaching effect of task card teaching mode in chemical experiment is verified through teaching practice.The fourth part: by analyzing the data obtained from practice,including after-school testing,final examination,student evaluation scale,questionnaire survey,interview and other data,it is tested the effectiveness of task card teaching mode in high school chemistry experiment teaching.The fifth part: it is summarized the positive role of task card teaching mode in high school chemistry experiment teaching,reflected the shortcomings of the research,and provided some ideas for future scholars to improve the research.The teaching practice shows that the application of task card teaching mode in chemical experiment teaching can help students improve their chemistry scores,enhance their interest in learning chemistry,and mobilize their subjective initiative in learning chemistry to the greatest extent.It can also strengthen their mastery of basic knowledge and skills,improve their awareness of cooperation and interpersonal skills,and cultivate the core literacy and the way of thinking of chemistry.
