The Century-long Construction Of Chemistry Literacy In My Country's Middle School

As a programmatic document guiding teachers’ teaching and students’ learning,curriculum standards play an important guiding role in students’ growth.The proposal of core literacy in the 2017 senior high school chemistry curriculum standard has triggered a new round of upsurge in the cultivation of students’ literacy and ability.Studying the performance of discipline literacy in chemistry curriculum standards will help us clarify the development focus of curriculum standards and provide possible suggestions for the formulation of curriculum standards in the future.However,the current research in this field is not sufficient,especially the literacy research based on the Centennial chemistry curriculum standard.Based on this,this study will try to start from the Centennial chemistry curriculum standard,sort out its development context,and explore the performance and evolution logic of subject literacy in the curriculum standard,in order to provide targeted suggestions for the development of subject literacy in the chemistry curriculum standard.This paper collects and arranges a total of 43 chemistry curriculum standards from the constitution of Yinding middle school since 1902 to the chemistry curriculum standard of ordinary high school in 2017,and carries out the research by using the methods of literature research,text mining and qualitative text analysis.Firstly,using the literature research method,this paper combs the historical background and structural evolution of chemistry curriculum standards in the past century,and expounds the evolution characteristics and development laws of different periods and stages.Secondly,it analyzes the performance of discipline literacy in chemistry curriculum standards in the past century.On the one hand,it uses the big data analysis platform of nlpir master to convert the format of curriculum standard text content,process weight words,and grab the keywords of each stage of development,so as to analyze the content changes of discipline literacy in the four stages.On the other hand,the qualitative text analysis method is used to study the development of discipline literacy in the past century.The classification framework divides discipline literacy into four aspects: basic literacy,problem-solving,high-level literacy and general literacy according to the Pisa 2015 scientific discipline ability evaluation framework.Among them,basic literacy has two dimensions: basic ability and comprehensive ability,problem solving has five dimensions:practical application,experimental operation,cooperation and communication,scientific method and cognitive style,high-order vegetarian cultivation has two dimensions: discipline essence and innovative thinking,and general literacy has three dimensions: values,emotional attitude and personality quality.Finally,using the statistical analysis method,this paper makes a consistency analysis on the four aspects of subject literacy in the target text,content text and suggestion text.It is found that the development of China’s Centennial chemistry curriculum standards has a distinct era and historical evolution logic.The development of curriculum standard structure tends to be diversified and systematic from no clear structure,and the development of discipline literacy also presents certain stage characteristics.In the development process of the Centennial curriculum standard,chemistry discipline literacy generally presents a form of expression dominated by basic literacy and supplemented by problem-solving.In the evolution trend,the proportion of basic literacy gradually decreases,and other literacy gradually develops,especially problem-solving.In contrast,the development of high-level nutrition and general literacy is relatively weak and needs to be strengthened.For example,the basic way to promote the development of experimental and practical ability is to pay close attention to the basic aspects of the basic development of experimental ability and practical ability at the end of the 20 th century.After entering the 21 st century,the essence of the discipline has made a qualitative breakthrough,and has been completely explained in the concept and framework.The values have strong characteristics of the times.After the founding of new China,they have attracted attention and constantly carried out concept innovation.At the same time,cooperation and exchange,innovative thinking and personality quality are extremely scarce and need to be strengthened.In the research on the consistency of discipline literacy,it is found that the development of target text,content text and suggestion text is relatively balanced in problem-solving ability in junior and senior high school.Especially after entering the 21 st century,the proportion and proportion of the three texts are becoming more and more reasonable,which is the best among the four abilities.The other three abilities are unbalanced to varying degrees,especially the high-order vegetarian cultivation and general literacy.There are serious inconsistencies among the texts.
