Research On The Chemical Language Expression Ability Of Rural Junior High School Students Based On Scientific Enlightenment

The chemical language is a specialized language for expressing chemical thoughts.Chemical language is not only the basis of chemistry learning,but also a tool for us to use chemical knowledge.The expressive ability of chemical language is the basic manifestation of students' chemical literacy and is a necessary subject ability for learning chemistry.Due to the constraints of teachers and teaching conditions in rural areas,rural students are still in a disadvantageous environment in the formation of chemical language expression ability.The ninth grade is not the beginning of chemistry knowledge learning.Students have received a certain degree of scientific enlightenment before they learn chemistry.Then,based on the ability formed by the scientific enlightenment,some problems appear in rural junior high school students at the beginning of chemistry learning.Therefore,this study is based on the in-depth understanding of the essence of the chemical language expression of rural junior high school students based on scientific enlightenment,and puts forward the specific meaning and implementation suggestions of the integrated training of science and education.This research is based on the theory of development stages,Constructivist learning theory and the theory of learning habits.Nine 9th grade students from a rural school in H province in northeast China are selected to study the current situation of their chemical language expression skills when they learn chemistry.Semi-structured interviews are used.And narrative research.Through interviews and observations,conduct in-depth research on the specific expressions of students' written chemical language,oral chemical language,and chemical language manipulation.From the perspective of scientific enlightenment before chemistry studies,students' chemical language expressions based on scientific enlightenment are obtained.After the performance data,this study sorts out,summarizes and analyzes it,sorts out and summarizes the specific problem performance of rural junior high school students in various forms of expression,and analyzes the impact on their specific performance based on rural scientific enlightenment.Explore the direction and implementation suggestions of the integration of rural science education.The research found that under the different memory levels of the written expression ability of chemical language of rural junior high school students,the performance of written expression is related to the teaching methods and recitation learning methods they receive in the scientific enlightenment,and they are also affected by the learning formed in the scientific enlightenment.Habits and scientific literacy foundation;the flexibility of chemical language oral expression in communication is lacking,and the oral expression ability of chemical language of rural junior high school students is shown in the creation of the situation: the oral expression in the scientific enlightenment The creation of the situation tends to be closed questions make students accustomed to the verbal expression situation of fixed question and answer.This kind of thinking style of question situation is formed in middle school.Even in the open question situation,they still show dependence on fixed question and answer.The content of oral expression is presented: students are still in a fixed and unified chemical language,lacking independent thinking and oral expression under divergent thinking,facing different objects in chemical language oral expression,presenting oral communication that is biased towards classroom teaching questions and answers The preference of choice,in the immediate feedback evaluation of oral expression in chemical language,students are more concerned about the degree of difference between oral expression and recitation,and the teacher's affirmation of its accuracy.In the expression of chemical language operation of rural junior high school students,the students' experience in basic experimental operation in the scientific enlightenment is still blank,and the lack of basic operation knowledge and expression in terms of knowledge and skills,process and methods,emotional attitudes and values,operational expression skills and methods are not standardized,and emotional attitudes and values still need to be further improved.After the discovery of problems,the combing and analysis of materials,the researchers further from the three aspects of the construction of the teaching team based on the integration of science and education,the specific teaching practice guidance based on the integration of science and education,and the guarantee of the effect of the integration of science and education.Set out to put forward specific suggestions in terms of teacher team building,teacher teaching guidance,and effect guarantee.
