| Since the new curriculum reform,middle school biology curriculum has been paying more and more attention to students' participation in class and cultivating students' exploration ability.Based on the existing research foundation,this paper focuses on the construction of physical model in classroom teaching.Through the theoretical arrangement of modeling teaching,the representative contents of teaching materials are selected for teaching design and practice.The author believes that through the implementation of the teaching model based on the construction of physical models in teaching,it is helpful to improve students' classroom participation and learning effect.The teaching cases in this paper can also provide some references for the frontline teachers.Through the research of this paper,it is found that in the construction of physical model in biology class of senior high school,the corresponding content in the textbook can be read up first,and the part suitable for the construction of physical model can be screened out.Then according to the classroom teaching time to choose the appropriate construction of the physical model,focus on the student activities from the teaching design.At last,statistical analysis was made on students' grades,and comparative analysis was made on students' classroom study notes,and questionnaires were issued to draw research conclusions.In this study,the "flow Mosaic model of biofilm","the process of photosynthesis","the process of aerobic respiration" and "the process of mitosis" in required biology course 1 of senior high school were selected as teaching cases to construct the teaching design of physical model and implement.Considering the limited learning time in class,the final teaching practice is to construct graphical and graphical models to help students achieve their learning goals. |
