Unit Teaching Design Practice And Research On Improving The Core Accomplishment Of Chemistry Discipline In Senior High School

The goal orientation of China’s new round of curriculum reform is to develop students’ core accomplishment.with the release of the Ministry of Education’research result on China’s student development core competencies,the results of education starting from "teaching" to "cultivating people." At present,in high school chemistry teaching,the teaching methods of teachers are still greatly affected by traditional teaching.The common phenomenon is that class time is used as the basic unit of instructional design,and the fragmented knowledge is directly instilled to students,we just focus on the language skills for a long time and the development of contempt ability and students’ self-construction of knowledge were disregarded.in the senior high school The chemistry teaching,which is under the guidance of the core accomplishment of chemistry discipline requires front-line teachers to analyze and grasp the contents of teaching materials,transforms the teaching mode and students’ learning methods.The knowledge fragment that has the same teaching theme forms a structured teaching unit,and the effectiveness of the teaching design is ensured through the creation of scenes and the implementation of teaching activities.This article will mainly describe the basic ideas of unit teaching design based on the core accomplishment of chemistry discipline.It is based on the “ properties and applications of Sulfur Compounds” in the compulsory version of Senior High School Chemistry 1.with the guidance of the connotation and constructivism in the core discipline of chemistry.we can consider more about the design of unit teaching objectives and teaching activities and construct teaching unit more suitable.Through the method of action research,the specific cases were implemented in the classroom,and conclusions were drawn from questionnaires,student interviews and classroom observations.
