| Junior middle school chemistry extracurricular activities are an effective supplement to classroom teaching.However,due to various reasons,most chemistry teachers fail to carry out effective extracurricular activities according to their contents in teaching practice.Extracurricular activities in junior middle school chemistry can transform knowledge imparting activities into knowledge exploration activities under the Task-driven,which allow students to develop proactive learning attitude,using their own knowledge and experience to analyze problems and complete tasks through independent exploration and group cooperation.In the course of completing the activity task,students not only exercised their ability to find problems,respect objective facts,analyze problems rationally,and solve problems by hands-on,but also enhanced their ability to communicate and cooperate with others in their interaction with peers.The research is mainly based on previous studies of chemistry extracurricular activities,trying to build a task-driven teaching model of junior middle chemistry extracurricular activities and conducting preliminary teaching practice research.This paper firstly summarizes the previous studies of “the Task-driven” and “extracurricular activities” and “the application of Task-driven teaching mode in junior middle school chemistry teaching”.On this basis,the theoretical of this study is put forward: analyzing the teaching value of junior middle school extracurricular activities under the Task-driven.Discussing mission design requirements and combining examples to analyze three types of chemistry extracurricular activities: handcrafting,arts and culture,and scientific inquiry.This paper constructs basic link of the junior middle school chemistry extracurricular activities under the Task-driven: analyzing teaching objectives and designing tasks;Create situation and publish the task;Analyze tasks and clarify activity objectives;Team work to complete the task;Display tasks and evaluate summary.The paper applied the theoretical to carry out the teaching practice for 1 academic year and12 extracurricular activities,which presented the melodrama of “Analysis of the essence of electrolyzed water from a microscopic point of view” and “The Natural Circulation of Water”,the extracurricular activities of “Investigation on the Color of the Solution after the Reaction of Copper Oxide and Dilute Hydrochloric Acid” and “Reaction of baking soda and white vinegar,reaction of egg shell and white vinegar”.The paper also discussed the teaching effect through interviews with students and thought that,carry out extracurricular activities in junior middle school chemistry under the Task-driven is conducive to stimulating students’ interest in learning and training students’ comprehensive practical ability. |
