Tudy On The Connection Between The Module Of Homeostasis And Environment Of High School Biology And The Teaching Of Junior Middle School Biology

The convergence of junior and senior high school biology teaching content has received increasing attention.ince the junior year of the junior year does not involve biology,it is difficult for students who have advanced to high school to connect junior high school and high school biology knowledge.At the same time,compared with the junior high school biology knowledge,the difficulty and span of the high school biology knowledge are increased.The learning method of students in junior high school is no longer suitable for the study of high school biology.There is a problem that it is difficult to connect with junior high school biology knowledge.Adopting proper teaching connection principles and methods in high school biology teaching can effectively improve this phenomenon.Based on the questionnaire survey,this article takes the "steady state and environment" module of high school biology as an example,on the "regulation through the nervous system and the composition of the nervous system,the basic way of neuroregulation","through hormone regulation and hormones" The four sections of "Regulation","Ecosystem tructure and Understanding the Biosphere","Immune Regulation and Planned Immunity",in the form of teaching cases,analyze the connection principles and methods with the corresponding junior high school biology teaching content.The principle of connection includes the principle of subjectivity,the principle of operability and the principle of feedback;the methods of connection include the method of problem situation connection,the old method of introducing new ones,and the method of constructing knowledge networks.According to the research results,the following suggestions are made:first,teachers should fully grasp the academic condition,understand the students' knowledge base,and guide students 'learning methods according tothe actual situation;secondly,junior high school teachers should strengthen communication,and it is best to organize collective lesson preparation activities and deal with it well.The teaching arrangement of the connection content of junior high school;in the end,both teachers and students should pay attention to the connection point of the content of the junior high school textbook,analyze the textbook in depth,grasp the key,and make full use of the students' existing knowledge base to prepare for the explanation and learning of new knowledge.
