A Study On Chemistry Preview Of Senior One Based On "Advance Organizer" Theory

Pre-class preview is one of the important ways to guide students to learn,and the ability of a pre-class preview reflects the core quality of being good at learning.However,in today’s educational environment,many teachers ignore the preview before class,and there is no clear preview plan to guide students in learning,resulting in a poor preview effect.How can the preview effect for students be improved? Through extensive literature search and analysis,I found that the famous educational psychologist Ausubel put forward the “advance organizer” as a leading material,this introductory material has high generality and abstraction higher and stable and clear characteristics that can be used as a student of known knowledge associated with the content of the new study set up a “bridge”.Ausubel claimed that an “advance organizer” can be used before or during class to promote meaningful learning when students learn new content.As a result,this work proposed that the “advance organizer” theory be applied to senior chemistry pre-class preparation to encourage students to learn independently,increase the efficiency of chemistry preclass preparation,and provide pre-class practice reference cases for high school chemistry teachers.This paper’s main contributions are as follows:The research background,theoretical foundation,and concept definition were covered in the first section.The research background of this paper was clarified through consultation and sorting of relevant literature and materials,and the research status of domestic and foreign scholars on“advance organizer” and “pre-class preview” were sorted out.The research contents of this paper were determined by the practical research on the pre-class preview of senior chemistry class based on the theory of “advance organizer”.Simultaneously,the terms “advance organizer” and “high school chemistry preview” were defined to clarify the scope of the study.This study expounded on the guidance and enlightenment of meaningful learning theory,constructivism learning theory,and assimilative learning theory.The second section was to investigate the current state of chemical preview in senior one.A questionnaire was created using three dimensions of cognition: current situation,problems,and expectations,to investigate the current scenario of chemistry preview for senior students to better understand the current situation of chemistry preview senior students.The current status of chemistry preview organized by chemistry instructors in senior one,as well as the implementation of the “advance organizer” theory in chemistry preview,were grasped through interviews with senior one chemistry teachers.The third section was to study the construction of senior one chemical preview based on the“advance organizer” hypothesis.Firstly,the current form and type of “advance organizer” in the senior chemistry preview were examined.Secondly,the three-stage teaching method of “advance organizer” was used to build the chemistry preview plan,which was based on the design principle of the “advance organizer” approach in the chemistry preview of the senior one.The fourth content covered the chemical class preview design and implementation.This section selected the contents of the first volume of compulsory chemistry in the new edition of the People’s Education Press.The chemical preview scheme was designed by combining it with the theoretical foundation of previous research,the related concept definition,the current status of higher chemical preparation,design principles,and teaching mode.The theory of “advance organizer” was applied in the experimental classes for chemical class preview,while the control class did not need the preview plan for preview.Following the practice research,the preview effect was assessed using classroom observation,interviews with experimental class students,a monthly test,and test question analysis.According to the findings of this paper’s practical research,applying the “advance organizer” theory to the chemical class preview can improve students’ interest in learning chemistry,promote students’ active self-preparation,change students’ learning attitude,promote students’ thinking and problem-solving skills,improve the efficiency of students’ preview and chemical performance,and improve teaching efficiency.
