Research On Analogy Cognitive Design Of The People’s Education Edition High School Chemistry Textbooks (2019 Edition)

With the advancement of the reform of “New curriculum standards and New textbooks”,the “scientific method” repeatedly mentioned in the “General High School Chemistry Curriculum Standards(2017 Edition)” has attracted researchers’ widespread attention.The analogy method is one of the important cognitive methods in chemical science methods.Textbooks are important resources for teaching and learning.And building textbook content system based on students’ cognitive psychology is a basic requirement for textbook compilation.Currently,there are few studies focusing on the content and process design of analogical cognition in textbooks from the perspective of psychological teaching materials.This research will design an analytical framework suitable for analyzing the analogical cognitive design of high school chemistry textbooks on the basis of theoretical and empirical research of analogical cognition.The analysis framework takes the elements of analogical cognitive content and the elements of analogical cognitive process as the first-level dimensions,further forming a secondary dimension that includes analogy source,analogy target,relationship,encoding-retrieval,mapping,reasoning and application-verification,as well as multiple tertiary dimensions and specific coding items under its jurisdiction.Based on the above analytical framework,text analysis was conducted on the2019 edition of the high school chemistry textbooks.This study draws some conclusions through the collation and statistical analysis of encoded data.It was found that when the source of analogy is interdisciplinary knowledge,the real situation is mostly used.Abstract theoretical chemistry and structural chemistry are the most numerous knowledge modules of analogical cognitive design.The analogy sources of the elemental chemistry knowledge module are based on the knowledge of the subject.The vast majority of the analogical source and analogy target attributes are nature attributes,and the analogical target is understood from the perspective of “what it is and what it has”.Nearly 70% of the analogical cognitive design has a relatively complete analogical cognitive process,mainly based on the design of“encoding-retrieval-mapping-inferring-application”.The validation and inferring sessions are the most missing sessions.In general,the number of analogue cognitive designs is small,and the analogue cognitive content design is quite reasonable,but there is room for improvement.The design of analogous cognitive processes lacks clear correlation and also can be improved.According to the research results,this study puts forward some optimization suggestions for the compilation of textbooks to increase the number of analogical cognitive designs linked to macro reality,improve the connection between social production and life and knowledge,and focus on the interaction between analogy cognitive mapping and inferring sessions.At the same time,this study also puts forward some teaching suggestions for teachers to clarify and improve the analogical cognitive process,and explore more analogy materials about life,and pay attention to students’ use of textbook analogy methods.
