Exploration And Practice Of The Scaffolding And Exploratory Teaching Mode Of High-school Chemical Experiments Under The New Curriculum Standard

The new curriculum standards focus on the development of students' core literacy,advocating students to carry out independent cooperative learning,attaching importance to the development of literacy-based teaching,and comprehensively developing students' abilities in all aspects.Chemistry is an experiment-based discipline,and the teaching of chemical experiments is self-evident for students to learn chemistry.With the deepening of curriculum reform,the education model is constantly pursuing innovation.The traditional experimental teaching mode has not met the requirements of the new curriculum standards for students' ability development.The majority of front-line teachers who are chemical educators must actively explore adaptation.The effective strategies and approaches of high school chemistry experiment teaching have changed the teaching methods of ignoring the subjectivity of students,passive “doing experiments” and mechanical memory in the past experimental teaching.The scaffold-based inquiry teaching mode is one of the three teaching modes under the constructivist theory.It takes the "recent development zone" as the fundamental theoretical foundation and focuses on cultivating students' ability of independent learning and cooperative inquiry.This thesis combines the scaffolding inquiry teaching mode with the chemistry experiment teaching.Based on the related literatures of the "General High School Chemistry Curriculum Standards(2017 Edition)" and the Scaffolding Teaching Model,through questionnaire survey and interview method(including pre-test and post-test method),the questionnaires for the teachers and students of Fuzhou No.4 Middle School on the scaffolding inquiry teaching mode and the related learning situation were designed.By selecting the experimental class and the control class for comparison,the specific teaching cases and teaching practice were designed.This study includes three teaching design including "two-liquid" primary battery,the working principle of the electrolytic cell and explore the hydrolysis of salt.By analyzing the learning ability and the changes in academic performance of the experimental and control classes and after the practice,the conclusions of the experiment were finally obtained.Combining the scouting exploratory teaching with the chemistry experiment teaching under the new curriculumstandard is beneficial to improve the students' self-learning ability and stimulating students' interest in chemistry,and helpful for cultivating students' cooperative inquiry ability and innovation consciousness.Moreover,it will promote the cultivation of students' core literacy to a certain extent.Finally,this thesis put forward the reforming suggestions and research prospects for scaffolding inquiry teaching.
