The Application Of Model-construction Teaching Of Biology In Senior High School

High school biology knowledge abstraction, is various, the photosynthesis and respiration are two important physiological processes, occupy very important position in the high school textbooks, are involved in the calendar year the university entrance exam, is the teacher’s teaching and student learning biological tough "crack". In this paper, the cause of the research on model construction, its applied in the teaching practice of the two chapters, using questionnaire investigation and practice study to study to solve the following problems:(1) higher in 48 students know the situation of the construction of the model and the model and the reason analysis; (2) of the construction of the model of general procedures applied to the actual classroom teaching have effect; (3) to find the best opportunity to use modeling teaching and strategies.This study to model construction as the carrier design questionnaire, understanding of the high student model and model construction situation investigation, survey showed that:(1) the students understanding of model is one-sided, remains to be improved; (2) students in biology class at ordinary times is rarely used modeling; (3) the teachers in the teaching process is not attach importance to the application of the model, also won’t be able to implement the new standard requirements for students to grasp the method of model. In view of this, on the basis of the author to the photosynthesis and respiration sections as the research content, the teaching model construction respectively applied to the two new lesson teaching, practice, review classes are brought up two classes in the classroom teaching practice, and the two classes as that in comparative classes and experimental classes, construction model is used in experimental class teaching, the use of conventional teaching that in comparative classes. After have a special test for the results obtained by these two class, with the advantage of data analysis model to construct the teaching, the problems existing in the teaching reflection and thinking to the problem. With the practical action for the superiority of model and model construction, reference for teachers, enhance the confidence of the teachers to construct the teaching by using the model.In this study the following conclusions:(1) model to construct the teaching can effectively help students break through biological difficult point content; (2) model to construct the teaching is beneficial to students integrated biological knowledge, constructing knowledge framework; (3) the model construction speed and quality of teaching can improve students’ problem solving; (4) modeling teaching help teachers change the teaching idea.
