A Survey Study On The Level Of Chemistry Basic Concepts In Senior High School Students

To improve the Core literacy of the students for the purpose of the Chemistry curriculum reform,requiring chemistry teaching must go beyond the specific knowledge of learning,and guide students through a high level of thinking to form chemistry basic ideas,from "knowledge-based" teaching to "ideas construction",to cultivate students' academic thinking and ability.This paper takes the "level of chemistry basic ideas of senior high school students" as the research core,under the guidance of chemistry basic ideas and the teaching theory of "ideas construction",drawing on the results of relevant research at home and abroad,on the basis of analyzing the connotation of chemistry basic ideas and the relationship with the teaching contents,the test volume of chemistry basic ideas is compiled and the level of chemistry basic ideas of 240 high school students in Ningxian H Middle School was measured,the survey data were analyzed for descriptive and inferential statistical analysis by SPSS18.0.The results show that first,the senior students' energy idea,classification idea and chemical values can basically reach the level of understanding,which can basically achieve the level of memorization for element idea,particle idea,change idea and experiment idea.Most students focus only on the knowledge itself,neither focuses on the formation of knowledge nor the consciousness and ability to apply chemistry basic ideas to solve problems.The chemical concepts and theories are simply mechanical memories that lack a deep understanding.Second,there is no significant difference in chemistry basic ideas between male and female students.It shows that gender has no significant effect on chemistry basic ideas of senior students.Third,there are significant differences in element idea,change idea,classification idea,experiment idea and chemical level,and there is no significant difference in the level of particle idea between regular class and the major work class students.This study aims at the level of chemistry basic ideas of students,and puts forward the chemistry teaching strategy based on "concept construction",including the promotion of teacher's own chemistry basic ideas' level,penetration chemistry basic ideas in the teaching process and through the reviewing and summarizing to enable students to establish the overall level of chemistry basic ideas,etc.
