Design And Application Of High School Chemistry Guide Case Based On Anchored Teaching

With the promulgation and implementation of the Chemistry Curriculum Standard of General High School(2017 edition),how to help students to learn and change the way of passive learning has become a difficult problem for most educators.The teaching mode of guiding case is to guide students to study independently and explore cooperatively,as well as emphasizes on student-centred.But the guiding case isn't good in the process of teaching practice.For example,the content design of guiding case is lack of inquiry,and its completion rate is low and so on.The Chemistry Curriculum Standard of General High School(2017 edition)writes: Real and specific problem situation is an important platform for the formation and development of students' core literacy in chemistry.Anchored teaching emphasizes the role of learning situation,and puts forward the cooperative activity based on solving real problems as the main way for students to learn knowledge.Therefore,this paper tries to combine the guiding case based on anchored teaching to form a new teaching mode,that is the senior high school chemistry guiding case based on anchored teaching.There are three main points in this paper:(1)to understand the current situation of conducting the guiding case in the chemistry in the middle school and the students' demand for the composition of the guiding case;(2)composition and principles of high school chemistry guiding case based on anchored teaching;(3)case design and practice analysis.At first,this paper uses the questionnaire survey from the perspective of the students to understand the guiding case in high school and the demand of students to guiding case,which will determine its composition as follows: learning goals,difficult point,self-study before class,scene creation,classroom inquiry,consolidation and upgrading,and activity evaluation,and the same time it can lay a realistic foundation for the construction of the model.Based on the analysis of the theoretical basis of the model construction,this paper determines the principles of the composition of the guiding case based on anchored teaching.And then,under the Chemistry Curriculum Standard of General High School(2017 edition),taking the knowledge of metal element compounds in the compulsory chemistry course 1 of senior high school as an example to design the guiding case based on anchored teaching.Through the second and third unit test scores comparison and questionnaire survey,this paper analyzes the implementation of the senior high school chemistry guiding case based on anchored teaching.Study shows that compared with the traditional teaching method,use the guiding case withanchored teaching in teaching can improve students' autonomous learning and self-monitoring.
