Analysis Of Teaching Material Of Modern Biotechnology Elective 3 In Human Education Edition Of Senior Middle School Biology And Discussion On Teaching Strategy

As the first-hand materials that teachers and students come into contact with in the daily teaching process,teaching materials are an important bridge connecting teachers 'teaching and students' learning of biological knowledge.Compulsory textbooks focus on basic knowledge learning,elective textbooks are dedicated to the individualized development of students and broaden their knowledge.The elective 3 textbooks,while expanding students 'knowledge reserves,present the forefront of biotechnology and become an important material for cultivating students' experimental exploration ability.However,due to the limitations of fast technical updates and strong practicality,there are some problems in the course.Based on the actual teaching,this paper conducts a comprehensive analysis of the human biology version of the elective 3 textbooks,provides a basis for teachers to reasonably grasp the content of the textbooks and promote classroom teaching.At the same time,combined with the investigation and research on the teaching situation of the Biology Elective 3 textbooks,suggestions are made based on the actual problems in the teaching to promote the teaching and learning of Elective 3.This article mainly solves two problems:(1)conducting a comprehensive research and analysis on the human biology version of the elective 3 textbook;(2)investigating the relevant teaching situation of the elective 3 textbook and making suggestions.The first question,the author collected and researched a large number of literature related to the analysis of teaching materials,first interpreted the description of the elective content in the curriculum standards,then established the research of this thesis on the basis of previous studies.The analysis of the background of the times and the overall analysis of the textbook,the overall analysis of <structural system,external contact,internal contact>)and microscopic(surface and deep systems).Finally,the difficulty of the textbook and the consistency of the textbook with the 2003 curriculum standards are analyzed.The second question,the author mainly adopts the questionnaire survey method and interview method.Taking advantage of the opportunities for the continuing education and training of teachers of the Xinjiang Production and Construction Corps,a questionnaire survey was used to collect data from teachers in 17 schools around the Corps and then random interviews were conducted.At the same time,author also conducted interviews with students at the internship school.Finally,the author combined the results of textbook analysis and survey data analysis,put forward suggestions on teaching and learning of elective 3 textbooks,where the textbooks can be improved.Through investigation,it was found that teachers have the following problems in elective 3 teaching: the choice of elective textbooks tends to be less experimental;the use of tutorial and theoretical columns in textbooks is higher,the use of practical columns is lower;the teaching method is single,lacking teaching video and picture materials of elective 3;lack of experimental experience related to technical operation of elective 3 textbooks.When students study the content of elective 3,due to the content is more theoretical,they are difficult to understand at the micro level,they have a sense of burnout,they also don't have a good habit of reading the textbook carefully after class.In summary,the author proposes improvements from the following aspects:(1)At the social level,related enterprises and scientific research units can provide learning opportunities such as visits;(2)At the school level,the middle school establishes a connection with the university,promotes the biology teaching in the middle school with the help of the university platform;(3)At the teacher level,try to use a variety of teaching methods to enrich classroom teaching,learn to integrate and choose between textbooks content,pay attention to the practice column teaching,increase teachers' opportunities for training of experimental modules;(4)At the student level,return to the textbook itself,effectively use the textbooks to learn,set up a biology Study groups,to compare knowledge,summarize and learn.
