Practical Research On Biology Diagrams In The Teaching Of Important Concepts In Junior Middle School Biology

In the Compulsory Education Biology Curriculum Standard(2011),teachers are required to pay attention to the teaching of important concepts,put forward "pay attention to the learning of important concepts",which points out the core position of "important concepts" in the knowledge system of biology discipline,and the important concepts become the existence that must be discussed in the current biology teaching of junior middle school.The new curriculum reform requires the cultivation of students' ability of hands-on operation and self-study.The sketch of biology can not only be abstracted into concrete,but also help students better understand the important concepts of biology.The teaching method of independent drawing can also cultivate students' drawing ability and promote students to solve practical problems.According to the observation,at present,the first-line teachers do not have a high awareness of letting students draw the biology sketch independently,and at the same time,the students' drawing ability is relatively weak,so it is necessary to get the results through scientific investigation and put forward solutions.This paper uses literature review method to sort out the research status at home and abroad and define the core concepts.The current situation obtained through investigation and research is as follows: 1.Most schools attach importance to the application of biology sketch in the teaching of important concepts;2.Some novice teachers rely too much on textbooks and multimedia,and draw less biology sketch;3.Students have high interest in drawing,weak drawing ability,and less opportunities for independent drawing;4.Teachers seldom use drawing biology sketch in biology concept teaching method.In view of the above problems,this paper puts forward the specific teaching strategies of biology sketch in the teaching of important concepts: 1.Introducing and viewing the map,introducing the important concepts;2.Blackboard supplement map,forming the important concepts;3.Independent drawing,processing the important concepts;4.Applying sketch,storing the important concepts;5.Working drawing,improving the important concepts.According to the design of teaching cases in LiaoNing Province Experimental School for practice,the final evaluation and analysis of teaching effect.The conclusions of this study are as follows: 1.Based on the investigation and research,we found the current situation of the application of biology sketch in junior high school biologyteaching;2.Based on the current problems,we put forward the teaching strategy of applying biology sketch to promote the learning of important concepts;3.Through practice and evaluation,we proved that the teaching strategy has achieved good teaching effect.The teaching strategy of biology sketch in the teaching of important concepts of biology has the value of teaching application to a certain extent,and it has certain reference for the teaching of biology teachers.
