Research On The Application Of Daily Necessities In Junior Middle School Chemical Experiments

Chemistry is a science based on experiments.Chemical experiment plays a fundamental role in chemistry teaching and is also one of the ways for students to learn chemistry.According to the experimental teaching content of the PEP chemistry course,which is compulsory but close to the students' daily life,and focusing on training students to use the chemistry knowledge and chemistry principles they have learned to explain the phenomena in life and solve problems.Combining with chemistry experiment teaching in junior middle school,the application of daily necessities in junior middle school chemistry experiment is proposed;aiming at chemistry experiment teaching to be carried out orderly and effectively in junior middle school.In turn,the students' experimental ability would be improved and their craving for chemistry in the enlightenment stage would be stimulated then,at the same time,their core qualities are cultivated as well.Combined with the four principles of scientificity,safety,practicability and environmental protection,this research is based on the theory of Sachman's Inquiry Training Model,Bruner's theory about Discovery-Learning,Dewey's "Learning by Doing" theory and humanistic learning theory,targeting daily development of daily necessities for junior high school chemistry experiment teaching class after holding a deep understanding of the chemistry teaching progress and the teaching materials in junior high school.Under the characteristics of daily necessities used in chemical experiments and the actual situation in this area,the daily necessities are used to develop and design junior high school chemical experiments to improve students' experimental ability and let them truly experience the chemistry in life.There are 6 chapters in this thesis,of which chapters 3,4,and 5 are the focus.The content is to investigate the development of the application of daily necessities applied to the chemical experiment teaching in junior high schools in the county,including teachers and students' attitudes to chemical experiments on daily necessities,related comprehensive skills and other conditions providing a basis for the research of this thesis.Combined with the actual situation in this area,7 extracurricular experimentally chemical activities such as kitchen series experiments and water-related series experiments were carried out orderly and effectively in our school,which fully demonstrated that daily necessities were used in junior high schoolchemistry experiment teaching is possible,feasible and controllable.The research of this topic shows that the junior high school chemistry experiment of daily necessities greatly enhances students' interest in chemistry learning,creates a daily atmosphere in classroom and focuses on the close connection between chemistry and life,and then to cultivate students' love of science and yearning for a better life.This research will continue to enrich and improve the daily life experimental cases and effective classroom records in chemical experiments,to provide more experimental materials for chemistry teaching in Yuanjiang County and better serve the first-line chemical experiment teaching.
