| Education reform has always been concerned,and the key of education reform is curriculum reform,which focuses on the reform of teaching materials.The biology curriculum standard(2017 Edition)of senior high school requires that the teaching materials should take "core literacy as the purpose","content focus on big concept","teaching process focus on practice" and "academic evaluation promotes development" as the basic concepts.In order to implement the requirements of curriculum standards and achieve the teaching objectives more effectively,this study uses the advantages of other versions for reference.This paper makes a comparative analysis of the textbooks of 2019 and 2007,aiming to explore and analyze the characteristics of the two editions and the implementation of the new curriculum standard...It provides reference and suggestions for teachers' teaching and students' learning.In this paper,the research object is the 2007 and 2019 edition of molecular and cell,which is the compulsory course of senior high school biology.Based on the general senior high school biology curriculum standard(2017 Edition),and based on the cognitive development theory,humanism theory,constructivism learning theory and lifelong education learning theory,the relevant literature is summarized by using the literature research method.By using the method of comparative analysis,this paper makes a comparative study on the content characteristics,significance and value,compilation structure,exercise design,illustration configuration,column setting,experiment type and quantity setting of the textbooks in 2007 and 2019.The results are as follows:(1)there is little difference between the2019 edition and the 2007 edition in the compilation structure,which is arranged in the order from micro to macro,from simple to complex.On the basis of the textbook of 2007 edition,2019 edition has made fineadjustments to the content,which is more in line with the students' understanding rules and teachers' teaching principles.The curriculum standard "the selection of teaching material content should meet the requirements of students' cognitive law,psychological characteristics and knowledge base".(2)There are two types of exercises in the 2019 edition textbook section: concept testing and extended application;chapter exercise types are connected with college entrance examination questions,which are divided into multiple-choice questions and non multiple choice questions,with a large number of questions.It embodies the value of education and the characteristics of the course,and creates the examination questions to examine the core quality of students.The curriculum standard "guides students to establish life concept,scientific thinking,scientific exploration and strong sense of social responsibility" Requirements of biological science literacy.There are various types of exercises and chapter exercises in 2007 edition.(3)The illustrations of2019 edition and 2007 edition have their own characteristics.Some illustrations of 2019 edition are arranged in two pages with novel style and three-dimensional image.The illustrations in 2007 edition are vivid and beautiful.Both editions of the textbooks have reached the goal of "the overall style of the textbooks is the same,forming their own characteristics".(4)There are differences in column settings between2019 edition and 2007 edition.2019 edition column integrates 2007 edition textbook with clear column contents,reflecting the principle of "less but better" in curriculum standard "curriculum design and implementation".There are various column settings in the 2007 edition,which are very rich.(5)The number and types of experiments in 2019 and 2007 are basically similar.There are many exploratory experiments in 2019,which emphasize the creation of real experimental situations and the cultivation of students' creative thinking.It is in line with the requirements of the curriculum standard that "based on the real situation,guide the students to think actively,explore actively,and innovatebravely in the process of exploration,so as to develop the core quality of students".The detailed experimental steps in the 2007 textbook are helpful to improve the students' practical operation ability.On the basis of inheriting the advantages of 2007 edition,2019 edition textbooks have been optimized and updated,paying more attention to practice,improving students' scientific literacy,and cultivating students' creativity and exploratory spirit.The 2007 edition is generally written in a style that conforms to the characteristics of students' thinking and pays attention to the learning of basic knowledge and the connection between disciplines.Suggestions are put forward on how to write the teaching materials,how to teach better and how to learn more efficiently.The suggestions for the compilation of teaching materials are: to strengthen the content of emotional education and safety education in the experimental content.The suggestion for teachers is to organize inquiry learning and pay more attention to the development of students' biological literacy.We should pay attention to the education of mutual relations among science,technology and society.The advice for students is to find a suitable memory method and avoid rote memorization.And in learning biological knowledge,we should pay attention to the contact with daily life,and more extracurricular practice. |
