High School Chemistry Alien Concept And Change The Text Research

Conception is not only an important content of chemistry knowledge in high school, but also is the premise and basis to mastering and understanding other knowledge, the high school teachers should attach importance of learning conception. The conception "chemical equilibrium" is not only one of the most important basic conceptions but also one of the most difficult conceptions in high school chemistry.The paper’s topic is Research of the alternative conceptions and conceptual change texts of high school chemistry and chemical equilibrium as a case. It discusses the ingredient and structure of conception, the basic theoretical and influencing factors of conceptual change, the ordinary teaching course of conceptual change, the rationale of conceptual change text, the content and characteristic of chemical equilibrium’ conception, the common alternative conceptions and the reasons of producing cause, the interview with teachers and students which including22persons about the understanding conceptions and the forms and reasons of producing alternative conception, compiling questionnaire and examining the147students of grade two, teaching practice to13students who come from the examined which use four conceptual change texts which compiled according to the conclusion of inspecting, examine the13students with an other questionnaireThe teaching practice shows, after using conceptual change texts in the teaching process, it can reduce study difficulty, improve chemistry performance, increase interest in chemistry learning and expand question thinking of students. At the same time, we draw three conclusions. The first, alternative conception is ubiquitous in chemistry studying and we should pay attention to it. The second, it must have reasons of producing alternative conceptions and we should find it and utilize it. And the last we should attach importance to conceptual change text in the chemistry teaching process. The results and conclusions of this study can provide references and application samples for the conceptions teaching of chemistry curriculum in high schools.
