Literacy-oriented Teaching Exploration Of Common Functional Groups In Organic Chemistry

The 2017 edition of senior high school chemistry curriculum standard(referred to as the new curriculum standard in this paper)proposes to develop the core literacy of senior high school students in chemistry,to carry out "literacy-oriented" teaching and to evaluate the core literacy of chemistry.In the new curriculum standard,both compulsory courses and elective courses have specific content requirements and academic requirements for functional group-related knowledge.However,in the current actual teaching,most students cannot fully integrate and absorb functional group-related knowledge and establish an effective cognitive model of functional group transformation due to the influence of factors such as traditional teaching mode,single teaching means,teachers' time arrangement or school conditions,etc.Therefore,it is the significance of this study that how to make students break through the important and difficult points of organic chemistry functional groups and build cognitive models to achieve the purpose of developing chemical core literacy.In this study,through combing the literature related to chemical core literacy and functional group teaching,and interviewing teachers and students,we know the degree of mastering functional group knowledge of senior two students,find out the obstacles and difficulties that students encounter in learning functional groups in organic chemistry,and analyze and determine the teaching mode of functional groups based on the existing research combined with the characteristics of disciplines.Choose common items in life,organize core literacy-oriented classroom cases in the form of review lessons,and carry out teaching practice.Through case implementation and effect evaluation,it is verified that this functional group innovation experiment inquiry teaching can enhance students' understanding of functional groups and develop students' chemical core literacy,and its research cases can provide reference for teaching practice.The paper consists of five parts:In the first part,through analyzing the literature,we know the research status of the core literacy of chemistry and the teaching of functional groups in organic chemistry,and summarize the characteristics and shortcomings of the status quo,so as to clarify the main direction and significance of this research;Define the related concept in this paper.In the second part,according to the current research situation,the research objectives,research methods and research ideas of this study are clarified,and the overall framework of this study is constructed.In the third part,through interviews and surveys,we can find out the degree of the students' mastery of functional groups in senior two,and find out the obstacles and difficulties that students encounter in learning functional groups in organic chemistry.Based on the guidance of chemical core literacy,innovative teaching cases of Inspection of Common Functional Groups and Transformation between Common Functional Groups are designed.The fourth part,practice and evaluation.Based on the definition and division of chemical core literacy in 2017 edition of chemistry curriculum standard,the evaluation index of chemical core literacy was established,and the questionnaire questions were designed based on the description of functional groups.Two parallel classes are selected for a comparative experiment,and the pre-and post-test data of the two classes are analyzed horizontally and vertically to verify whether this teaching practice can effectively improve students' chemical core literacy.The fifth part summarizes the research,draws the research conclusions and analyzes the research deficiencies.Through the research,it is found that,compared with the traditional experimental teaching mode,this literacy-oriented functional group activity teaching case can improve students' learning enthusiasm and understanding of functional groups,and can improve the core literacy of chemistry to varying degrees.At the same time,there are still some shortcomings in this study.
