Research And Practice On Real-Life Context-Based Chemistry Instruction In Middle School

It has been a hot issue in the history of education regarding the relationship between education and life. This is also true of the curriculum reform in China and foreign countries. The new curriculum reform in basic education in our nation advocates that the curriculum content and teaching methodology should be closely related to the students' life and experiences. Chemistry is a kind of science, which is closely connected with the life world. The "Exploring from the life world into the world of chemistry and the exploring from the world of chemistry into the life world" is such a discipline, which is very much related with the life. In teaching practice, teachers are accustomed to paying more attention to chemistry first, life second, that is, they teach students chemistry knowledge first, then guide them to apply it in the life world from the knowledge they have learned. But they pay less attention to explore from the life world into the world of chemistry. The problem exists in the educational beliefs and doubt they hold. This thesis puts forward the idea of middle school chemistry teaching being closely related with the real life world based on the belief that chemistry is part of life.The thesis uses documentary methods, questionnaires, interviews and case studies. Based on the theories of constructivism, situated cognition and STS education integrated with the chemistry instruction in middle school with authentic life as the basis, we have investigated the relationship between different real-life contexts and students' interest differences, their formation and transfer of concepts, between their contextualized problems in life and the research and practice of chemistry...
