Project-based Learning(Project-based learning,PBL)is a new teaching mode based on constructivist learning theory and task-driven,focusing on cultivating students' professional accomplishment.In this teaching mode,teachers combine theoretical knowledge with practical skills to design activities related to social hot issues,production and life.Students take the group as the unit to participate in the implementation of the project,complete the project within the specified time,and show and evaluate the project.In the project activities,students can not only master the theoretical knowledge of the subject,but also improve the relevant learning skills and promote the subject effective implementation of literacy.In recent years,the project-based learning model has attracted more and more attention from all walks of life.Under the control of traditional teaching mode,it is the general trend to design and develop a series of high school chemistry project learning courses.Therefore,based on the implementation of the core literacy of chemistry,this paper studies the high school chemistry project learning.With the rapid development of the times and the development of the core accomplishment of chemistry,the society demands more and more talents,and it is difficult for middle school students to transfer and apply the knowledge they have learned,and the comprehensive learning ability is weak.Based on the above problems,the author tries to use the project-based learning model to promote students' comprehensive ability and implement the core accomplishment of chemistry.Based on the analysis of domestic and foreign literature,this paper defines the concept of project-based learning and core literacy in chemistry,summarizes the four teaching design principles of "literacy-oriented ",fully excavates the connotation of literacy in teaching materials,and promotes the all-round development of students.Then the author The connotation of the core accomplishment of chemistry subject,the analysis and summary of the teaching procedure of the project-based learning model,provide reference for the design and development of a series of project curriculum resources.The project-based learning teaching design for developing the core accomplishmentof chemistry is the core content of this research.This topic selects three parts of silicon,chlorine,sulfur and its compounds in the compulsory "nonmetal and its compounds" unit of senior high school chemistry teaching edition to carry on the case design.After teaching practice,data collection and statistical analysis of experimental results are carried out by means of questionnaire survey and interview outline,based on the obtained results Data obtained,analysis of the application of project-based learning in chemistry classroom effectiveness and relevant recommendations. |
