A Research On The Constructivism-based Teaching Connection Of Elements And Compounds In Junior And Senior High School

Since the curriculum reform,the Curriculum standards of Junior and senior high school have undergone great changes.Compared to junior high school,the new curriculum standards of high school have higher requirement for students.For the first grade students of high school,chemistry is a relatively difficult course.Especially for the elements and compounds,students always feel that knowledge is scattered and messy,and there is too much contents need to remember.So it is more difficult to learn.This paper combines constructivism theory,and discusses how to solve the problems of the teaching convergence of elemental knowledge in junior and senior high school.The results showed that,constructivism takes the student as the subject,and let students construct knowledge forwardly.This idea plays an important role in the connection of the knowledge between junior and senior high school.And it can help students form a good learning habits,enhance the enthusiasm and initiative of learning chemistry.Thus students can enter the high school curriculum stage successfully.This paper studies the theory of constructivism,sum up the problems of elements and compounds in bridging teaching which should be pay attentioned to.And work out reasonable teaching designs,at the same time conduct a teaching experiment.This teaching research is carried out in a high school in pulandian district of dalian.This test aims at two parallel classes in the first year of high school,and the test time is three months.This article is based on the analysis and collation of related literature,and sums up previous experience.And use inteiviwe and questionnaire method.To understand the teacher's views for the teaching convergence and the study questions that students generally exist in the high school first grade.Starting from the knowledge of element compounds in junior high school,and analyzing its convergence situation.Improved on the basis of the original teaching model.Using the theory of constructivism to carry out teaching design.And select two representative lessons plan for reference.Through a questionnaire survey of students and the analysis of the test results after teaching experiment,gets a conclusion that achieves better results using constructivist teaching model when students have similar basic level.The class implement teaching connection bases on constructivism,its performance is significantly higher than the other class in the traditional teaching model.This means the method has great benefit to the convergence of elements and compounds content,and it can solve the problem of teaching convergence in elements and compounds content effectively.
