Research On Teaching Strategies Based On The Comparison Of Textbook Image System

The image system of biological textbooks is the most intuitive,visually impactful,and most capable of organizing and integrating important information.It plays an irreplaceable role in carrying information,developing students’ core literacy,and realizing the value of educating people.This research takes the biological textbook image system in 2019 and 2007 as the research object.Through the literature method,comparative research method and interview method,it summarizes its appearance characteristics,content characteristics and educational functions,and analyzes the 2019 Core literacy,based on this as a basis to propose image teaching strategies.The purpose is to provide reference and help for teachers to use textbook image system deeply and efficiently in teaching.There are six chapters in this paper:The first chapter is the introduction.The author determined the research direction of the thesis by combing the research background of the comparison of image systems of biology textbooks and teaching strategies.The third chapter is about the object,content and method of the thesis.The fourth chapter is the comparison results of the visual features,content features,and functions of the two editions of the textbook image system and the presentation results of the core literacy of the 2019 textbook.In the 2019 edition of the textbook,there are more structured images,combined images,large-format images,color images and three-dimensional images.The organization of images and text is more reasonable,and the content of interdisciplinary is more,more scientific and appropriate,which reflects the core quality of the discipline.The fifth chapter is the image teaching strategy.According to the characteristics of the 2019 version of the textbook image system,combined with the teaching experience of frontline teachers,the selection strategy,presentation strategy and use strategy of image teaching are proposed.Combining the teaching content to choose physical images,model diagrams or schematic diagrams,etc.;choose larger,bright colors,high-quality images with high definition.The presentation of static images should take into consideration the feedback of students and adjust the hold time immediately.The presentation of dynamic images must combine visual,auditory,and tactile sensory stimuli.Before presenting the images,it is necessary to build a teaching scaffold for students,and pay attention to the organization and deployment of images.When using images,we must pay attention to the modification and processing of the image system,be good at combining other teaching elements,and pay attention to the penetration of teaching concepts in image teaching.The sixth chapter is conclusions and recommendations.Summarize the research results of this paper,and put forward three suggestions for teachers to use image teaching:1.Improve the understanding of textbook image system 2.Develop the practical ability of processing images 3.Practically cultivate the core literacy of students.
