The Establishment Of Inquiry Chemistry Teaching Cases In Junior High School

With the rapid development of economy and culture,the society has higher standards for the requirements of talents.As a fundamental task of education,"Morality Education"needs students to develop in an all-round way,and education should advance in a modernized direction.The China Professional Degree Teaching Case Center was officially launched in 2013 with the aim of benefiting more teachers and students.Different from the regular teaching cases,the professional teaching cases are more prominent in story,locality and conflict.It is more readable and has a wider audience.Both front-line teachers and ordinary students can learn to read.With the further promotion of case writing and warehousing,various disciplines in various fields are actively implementing the innovation of case teaching mode,and chemistry education is no exception.The cases utilize the Constructivism as the theoretical support,with the principle of professional teaching case writing.Using the literature and case study method to sort out the current status of professional teaching cases and inquiry teaching,which can provide the basis for subsequent case writing.Before writing professional teaching cases,it needs to record excellent examples and videos,focus on restoring conflict points and story-telling plots.Then,selecting the three sections of junior high school chemistry in Science and Education to design and write different types of teaching cases,follow the format template of professional teaching cases.It will focus on planning different case thinking questions for the students to analyze and understand.The course of"Chemical Properties of Metals"is mainly from the perspective of inquiry experiment,through various exploration activities combined with history,life and application,etc.It will cultivate students’ability in all ways,encourage students to boldly innovate,and let students to show more.The course of "Preparation of Oxygen" is mainly to complete the transformation from "Three-dimensional goal" to "Core Literacy".It focus on cultivating students’ experimental inquiry and innovation consciousness as well as scientific spirit and social responsibility fused with relevant requirements."Water Purification" is mainly to create a variety of teaching situations,using different ways such as questioning,life,cooperation and practice to guide students to explore relevant knowledges and complete activities in a relatively relaxed atmosphere.The use of professional teaching cases is not limited to teachers,and its can be extensive.It is a self-improvement for teachers and a process of accumulating teachers’ professional qualities.People in the same course will have lots of designs,and teachers can find the type that suits themselves according to the "Lesson with Heterogeneous".Trying to write your own teaching case is a way for self-reflection and sublimation.Teachers will find problems that are subjectively unrecognizable from the third perspective.For students,professional teaching case is a supplement to knowledge.Students can use spare time to read it and self-study.Junior high school chemistry has its own unique position as a link between elementary science and high school chemistry.It emphasizes basic knowledge and experimental application,and inquiry-based teaching is suitable.The development of professional teaching cases has many advantages for individuals and the entire educational environment.Strengthening the study and writing of professional teaching cases is a powerful means to realize the new curriculum reform and cultivate all-round talents.
