Investigation And Research On Chemical Energy View Of Science Students In Senior Three

Energy is an important material guarantee for a country's stable social development and sustained economic growth.Energy has become a hot issue in the world.Major countries in the world regard energy security strategies as an important part of their national security strategies.Developed countries such as the United Kingdom,the United States,and Japan,as well as developed regions such as Taiwan,are actively engaged in energy education in the basic education stage in response to the energy crisis.In 2017,China promulgated the curriculum standards for ordinary high school chemistry,which emphasizes the cultivation of students' core discipline quality of "scientific attitude and social responsibility" and sets up the concept of sustainable development and green and low-carbon energy.The concept of energy is one of the core concepts in chemistry learning.At present,there are only a few literatures about energy view.Therefore,this study provides a certain empirical basis for the study of chemical energy education to a certain extent.In this study,literature review and questionnaire survey were used to study the students' views on chemical energy.Firstly,the definition,connotation and construction of related concepts of chemical energy concept are determined through literature review.Then statistics and analysis of junior high school,high school chemistry curriculum standards and energy-related content of the textbooks are made.Secondly,on the basis of the dimensions and contents of the “Chemical Energy View” questionnaire,the opinions of relevant experts were consulted,and the three dimensions of “Chemical Energy View”,namely “concept of energy”,“the perception of energy” and “the application of energy” were finally determined.A questionnaire that can investigate the status quo of students' chemical energy view was compiled,and the reliability and reliability of the questionnaire were tested.Finally,the author selected the high school science students from 8 schools in Chongqing to conduct surveys for the respondents,and issued a total of 415 questionnaires and 361 valid questionnaires.Through statistical analysis of the data,the following conclusions can be drawn:(1)The understanding of the concept of chemical energy of high school science students is not deep;(2)The understanding of the perception of chemical energy of high school science students is not comprehensive;(3)The chemistry energy application ability of science students in senior three is low;(4)students of different genders have significant differences in their chemical energy view,and students of schools in different regions have significant differences in their chemical energy view.Based on the survey results,the following suggestions are put forward :(1)Chemistry teachers should pay attention to the education of high school students' chemical energy view;(2)Chemistry teachers should conduct in-depth research on the relevant content of energy in chemistry textbooks;(3)Chemistry teachers should explore the factors that influence the formation of students' energy view,and cultivate students' chemical energy view in a targeted manner;(4)The chemistry teaching process adopts the teaching strategy guided by the problem group.
