A Comparative Study On The New And Old Teaching Materials Of "Molecule And Cell" Module In High School Biology

In 2003,the ministry of education issued the curriculum plan and curriculum standards(experiment)for ordinary senior high schools,which ha s guided the practice of curriculum reform in ordinary senior high schools for more than ten years.In December 2014,the ministry of education launched the revision of curriculum standards for all subjects in high schools,and completed the revision of the standards in early 2017.O n January 16,2018,the ministry of education held a press conference to officially promulgate the curriculum plan and curriculum standards for various subjects for ordinary high schools,including the biology curriculum standards for ordinary high schools(2017 edition)(hereinafter referred to as the "new curriculum standards"),and officially publish and use the new textbooks in 2019.In 2014 and 2017,zhejiang,Shanghai and Beijing,tianjin,shandong and hainan provinces launched the gaokao reform,respectively.In 2019,freshmen in senior high school in these provinces began to implement new courses and use new textbooks.In my internship in weifang shouguang in shandong province high school,as a high grade biology teacher,had the privilege of as the first use of the new teaching material's teacher,therefore,based on people's education press,the teaching material of countrywide middle and primary school authorized committee in 2004 first trial by the ordinary high school curriculum standard experiment textbook "creatures"(hereinafter referred to as the "old teaching material")and the 2019 national teaching committee approved the ordinary high school textbook "biology"(hereinafter referred to as the "new materials")required 1 "molecular and cellular" as the research object,using the method of comparative research,teaching material and content analysis method to compare the new textbook to the old teaching material improvements,Based on the specific practice,the author co mpares the two versions of biology teaching materials,helps teachers to quickly understand the changes and updates of the old teaching materials,and provides some references for teachers to prepare and teach.At the same time,the author puts forward his own views and Suggestions on how to better use the new teaching materials.This article mainly from the teaching material of the cover,table of contents,text content,program,the textbook illustrations,operation system and experiment of two materials in this seven aspects to comparative analysis of the system,and summarizes the advantage of the new teaching material,the specific content of mining development core literacy in the textbooks,and larger changes in the content of the section of teaching design,according to the practical problems encountered in the process of teaching and teaching feedback problems,in order to guarantee the student to biology more efficient learning,teachers to provide reasonable Suggestions to the teaching material.Based on the comparison of the old and new textbooks,it is concluded that the new textbooks have the following advantages over the old ones.1.More reasonable content arrangement;2.Guided autonomous and inquiry-based learning with a problem-driven approach;3.Knowledge points focus on the construction of biological concepts;4.Appropriately refine,explicitly or implicitly present the core accomplishment;5.Create real problem situations and develop core biological literacy;6.The textbook has clear pictures and close combination of pictures and texts.7.Multiple ways to strengthen students' self-evaluation;8.Obvious color differentiation on the page of the textbook;9.Add Chinese elements to reflect cultural confidence and enhance national pride;10.Improve the feasibility of student activities.Through comparison,the new teaching material is based on the old teaching material sublimation,improve,new teaching material basic inherit the old teaching material's content framework,careful analysis and retain the advantages of the old teaching materials,take its essence,in accordance with the requirements of new,innovative efforts,create the teaching content more conducive to development of students' biology core quality,improve the teaching material of educational value.Finally,according to the compilation characteristics of the new teaching materials and the requirements of the new curriculum standards,some Suggestions are put forward for the teaching materials and teachers based on the practical problems encountered in teaching and the teaching practice.
