Research On The Relationship Between Chemistry Learning Strategy And The Key Competences Of Chemistry Discipline In Senior High School Students

The concept of "key competences" is one of the important ideas in the curriculum reform of basic education in China,and it is also the theoretical conception of carrying out the fundamental task of "cultivating people with morality" in the 18th national congress of the communist party of China in the new historical period.As an important part of the development of students' key competences in chemistry,it is important to explore its influence mechanism and find strategies to improve it.Therefore,taking high school students in hubei province as the research object,the research questions are put forward as follows:(1)the core quality level of key competences of chemistry disciplinethe and chemistry learning strategies of high school students in hubei province?(2)are there significant differences in the key competences of chemistry in demographic background factors?(3)do chemistry learning strategies affect the acquisition of high school students' key competences in chemistry?What is the mechanism?(4)does family socioeconomic status have a moderating effect on students' chemistry learning strategies and key competences of chemistry?The study consists of five parts.The first part is the introduction,including the question,the theoretical and practical significance of the research,the research content,research ideas,research methods.The second part is the literature review,which explains the core concepts of "key competences of chemistry discipline","learning strategy of chemistry",as well as the relevant research review and theoretical basis at home and abroad.The third part is the research design,which explains the questionnaire data source and sampling,variables,questionnaire reliability and validity test,research hypothesis and hypothesis model.The fourth part,through the statistical analysis software SPSS 24.0,descriptive statistics,correlation analysis,the mean difference test,multiple hierarchical regression analysis,key competences of chemistry discipline and the present situation of chemistry learning strategies' to describe,the correlation between variables,and chemical differences between the demographic background of subject core literacy test,the main effect of chemistry learning strategies inspection and the regulation effect of family socioeconomic status.The fifth part expounds the conclusion,enlightenment,innovation and limitation of this research.The main conclusions are as follows:1.The level of key competences of chemistry discipline of senior high school students in hubei province is above average,from high to low,it is macro identification and micro analysis,change concept and balance thought,scientific attitude and social responsibility accomplishment,scientific inquiry and innovation consciousness accomplishment,evidentiary reasoning and model cognition accomplishment.2.The overall level of chemistry learning strategy of senior high school students in hubei province is above average,from high to low,it is followed by academic help strategy,adjustment strategy,retelling strategy,monitoring strategy,time management strategy,and processing and organization strategy.3.There are gender and grade differences in the key competences of chemistry discipline.The level of girls' key competences in chemistry discipline is significantly higher than that of boys.The key competences level of chemistry discipline in the second year of senior high school is significantly lower than that in the first and third year of senior high school,and there is no significant difference between the first and third year of senior high school.4.Chemical learning strategies positively affect the key competences of chemistry discipline of senior high school students.The combined predictive power of chemical learning strategies on macro identification and micro analysis,change concept and balance thought,evidential reasoning and model cognition,scientific inquiry and innovation consciousness,scientific attitude and social responsibility is 50.1%,52.3%,53.6%,52.3%and 49.7%,respectively.Specifically,processing organization strategy,adjustment strategy,and time management strategy rank the top three among the three chemical learning strategies in influencing each dimension of the key competences of the chemistry discipline.5.Family socio-economic status has a weak moderating effect on some dimensions between the various dimensions of chemical learning strategies and the key competences of chemical discipline.This paper studies the influence mechanism of chemistry learning strategy on the key competences of chemistry discipline,considers the moderate effect of family socio-economic status,and provides practical results for the reform of basic chemistry curriculum.It not only enrichs the key competences theory of chemistry subject,but also has certain guiding and enlightening significance for the practical research of chemistry education.
