Research On Causes And Correction Of Negative Migration In Senior High School Students' Chemistry Learning

This text is based on the study of high school students in a middle school in Shiyan,Hubei province.Under the guidance of the theory of pedagogical research,the research dimension of this study is determined.In the course of the study,the students and teachers were investigated by questionnaire to explore the causes of negative migration in high school students' chemistry learning.By improving teaching methods and carrying out paper and pencil test,we can verify whether the strategy is effective in teaching practice.The full text is divided into five parts.Chapter One Introduction:this part combines the educational background of the new curriculum reform,through referring to the relevant literature at home and abroad,understands the significance and present situation of the research,and clarifies the thinking and methods of the research.Chapter Two Relevant theoretical review:the meaning and characteristics of negative migration,the classification of high school students' negative migration in chemistry learning were determined by reading and combing a laige number of relevant literature.Chapter Three The negative migration law in high school chemistry teaching investigation and analysis:A questionnaire survey is conducted on the negative migration rules between teachers and students to investigate the negative migration status in the chemical learning and summarize the causes of negative migration.Chapter Four An experimental study on the causes and correction of high school students' negative migration of chemistry learning:After the pre test,the students were guided to analyze the errors.The appropriate teaching suggestions are put forward according to the results of the students' error analysis and the questionnaire survey.After a period of teaching practice,the chemistry results(average and average negative mobility)of the students were compared to verify the effectiveness of the proposed correction strategy.Chapter Five Research conclusion and reflection:Many factors may lead to the occurrence of negative migration,and the whole research process is practical.However,there are still some shortcomings,such as inadequate research object and incomplete strategy.Via this study,I found that the students' bad mentality,poor learning methods and imperfect cognitive structure,the teachers' improper teaching methods,improper test arrangements and bad textbook arrangement,would lead to high school students' negative migration in chemistry learning.Through the proper improvement of the teaching methods,the effectiveness of the strategy is verified in the teaching practice.The results show that through the full use of multimedia teaching to help students understand thoroughly;using the mind map to strengthen the memory of the students;writing the knowledge list and chemical reaction formula regularly to measure and evaluate the students' learning effect,and so on,effectively reduce the occurrence of negative migration.
