The Features And Case Analysis Of The New Textbook Of The "Molecule And Cell" Module For High School Biology

With the rapid development of science and technology,and the explosive growth of knowledge,the society has put forward higher requirements for people's comprehensive literacy,and school education should undertake the improvement of students' Scientific Literacy.In order to carry out the fundamental task of cultivating people with morality and deepening curriculum reform,the Ministry of Education launched the revision of the curriculum standards for all subjects in senior high schools in December 2014,and issued the "General High School Biology Curriculum Standards(2017 Version)" in 2018.The textbook writing is recreated on the basis of curriculum standards.Therefore,the promulgation of new curriculum standards will inevitably lead to the re-compilation and revision of high school biology textbooks.With the official launch of the new textbook of the People's Education Edition in September 2019 and the official release,the study of new textbooks has gradually become a hot spot,through consulting a large number of documents.It is found that the relevant researches are mostly focused on a certain angle of the teaching materials.This article will start with the systematic study of teaching materials,using literature research,comparative research,theoretical research and other analytical methods.Taking the new textbook molecular and cell of Senior High School Biology Human Education Edition as the research object,molecular and cell is the required content of senior one students,the core knowledge in the required course,and the primary learning module.At the same time,taking the experimental teaching materials as a reference,the characteristics of the new teaching materials are presented in terms of the selection of the times,the characteristics of education and the changes of the knowledge structure of the teaching materials.And according to the content of the two editions of the design of specific teaching cases,analysis of the characteristics contained in the teaching materials,to help teachers and students to make full use of the new teaching materials to grasp the context of changes in the new teaching materials,to provide a thin force for the implementation of the new teaching materials module of high school biology "molecules and cells".Compared with the old textbook,the changes of the new textbook of molecule and cell are as follows: first of all,the compilation concept of the textbook changes with the times,and the new textbook pays more attention to the development of students' core literacy in biology.Secondly,it analyzes the educational characteristics of the new textbook.Thirdly,the new textbook's educational objectives,knowledge structure arrangement system,presentation form,textbook exercise design and language and text further show the characteristics of the new textbook: 1.The column setting and activity type of the new textbook are more abundant;2.The new textbook pays more attention to the connection between knowledge and students' life experience;3.The knowledge distribution between the chapters of the new textbook is more reasonable and the connection is tight 4.The experiment of the new textbook is easy to operate.The new textbook pays more attention to the unified development of students' subject core literacy and curriculum knowledge goal.Based on the analysis of the characteristics of the new textbook,this paper puts forward the following suggestions according to the current situation of the compilation and teaching of the new textbook: 1.teachers should constantly strengthen their own learning and improve their professional quality.The new textbook increases the relevant cutting-edge scientific and technological knowledge,and puts forward higher requirements for teachers' knowledge background.2.Strengthen the understanding of the new curriculum standards,and integrate the basic concepts in the curriculum standards into the actual classroom teaching activities.3.We should study the textbook carefully and keep it close to the textbook.We should not adjust the teaching content under the old teaching inertia thinking.We should have an overall grasp of the depth and breadth of the content of the new textbook,which is based on the achievement of the core literacy of the biology subject.4.Attach importance to the active learning characterized by inquiry.Teaching is not only the process of teachers' explanation and demonstration,but also the interactive process of teachers and students' communication and common development.Attach importance to the creation of problem situation,which is connected with students' life experience,and promote students to change from passive acceptance of knowledge to active inquiry learning.Based on the analysis of the characteristics of the new textbook,this paper selects the new textbook protein,which is the main undertaker of life activities,to design a teaching case.Compared with the reference cases in the old teaching materials,the case design of the new teaching materials adjusts the order of teaching contents,conforms to the cognitive logic of students,embodies the compilation concept of the new teaching materials,and changes from paying attention to the internal logic of subject knowledge to paying attention to the cognitive law of students.On the basis of continuing the teaching objectives of the old teaching materials,the teaching objectives of the new teaching materials are integrated and improved The new textbook structure arrangement system conforms to the requirements of the new curriculum standard of "follow the logical sequence of knowledge from easy to difficult,step by step",which is helpful for students to understand and construct important concepts.In a word,through the systematic analysis of the characteristics of the new textbook and how to fully reflect the characteristics of the new textbook in the design of teaching cases,this paper will provide useful reference for teachers and students to use the new textbook efficiently.
