Analysis Of Structure And Characteristics Of After-class Exercises Of High School Biology "Molecule And Cell" Module

Biology is an important science course in high school.The textbook is compiled according to the curriculum standard,which fully implements the teaching content and curriculum objectives.That is to say,the teaching material is the written presentation of the teaching content,curriculum concept and so on.The use of teaching materials can better achieve the teaching objectives and play the educational effect.Exercises after class as an important part of the teaching materials,The after-class exercises play an important role in consolidating the biological knowledge.The first is that after-class exercises can consolidate knowledge and skills;the second is that after-class exercises can expand the knowledge field;the third is to cultivate students,thinking and ability;the fourth is to cultivate students,emotional attitude and values;the fifth is the feedback function;the sixth is the evaluation function.So how to effectively use after-school exercises has been praised by messages and biology teachers attention.In this study at home and abroad on the basis of summarizing the research situation of after-school exercises,the journal of molecular and cellular module after class exercises of the structure,characteristics,content and so on are analyzed,And as a case in Inner Mongolia Chi Feng City Ke Shen Ke Teng Qi Jing Peng Mongolian Middle school conducted a questionnaire survey,obtained the local high school students on the "molecules and cells" module after-school exercise attitude,degree of knowledge,the use of first-hand information.The results are as follows: 1.In terms of the structure of the exercises,the order of exercises,the type of exercises and the content of exercises are discussed.2.In terms of the characteristics of after-class exercises,it is concluded that the after-class exercises of this module are systematic,practical and open.3.As an example,investigates the Inner Mongolia Chi Feng city Jing Peng Mongolian Middle school,high school students to this module related questions of after-school exercises,obtained the following results:(1)the student to the homework problems understanding and evaluation of investigation can be seen that a majority of the students has a positive attitude to this module after-school exercises,this module and the class has a general understanding of the importance of the problem sets and function.(2)The investigation on the use of biology exercises after class shows that although students have a clear understanding of the function of the exercises after class,they do not make full use of the exercises after class.They will only choose the easier basic questions and will often ignore the more difficult extension questions.(3)The analysis and investigation of the reasons for students' neglect of after-class exercises.It can be seen from the reasons for restricting students' use of after-class exercises that the use of after-class tutorial books,the improper difficulty of after-class exercises,and the amount of questions for after-class exercises all limit students' use of after-class exercises to some extent.(4)A survey on the role of exercises after class and aspects to be improved.There are various answers to the open questions about the role of exercises after class,but most students think that exercises after class can help them consolidate the content and expand their scope of knowledge.When asked if there is anything to be improved in the exercises after class,most of the students said no.(5)In terms of students' Suggestions on using exercises after class,most students said that it would be better to do the exercises by themselves first and then explain them by the teacher.Other students think pictures and tables can help them understand the text more easily.In short,through research to understand the keshiketengqi Mongols high school students on the "Molecules and cells" module of the cognitive status quo,use of exercises after class exercise and ignore the reasons for exercise.At last,the paper puts forward the suggestion of using after-class exercises,that is,teachers should pay attention to the gradient of after-class exercises and the difference of students;Teachers are required to flexibly use the style of after-class exercises to realize the expansion of teaching functions;Teachers also need to create after-class exercise situation,pay attention to the link with real life;Attach importance to the study method guidance in the exercises after class.
