Teaching Design And Practice Research Of "Exponential Function And Logarithmic Function" Under UbD Theory

With the implementation of High School Mathematics Curriculum Standards(2017 Edition,2020 revision)(hereinafter referred to as curriculum standards),Cultivating students’ core quality has become a topic of concern in the educational circle.How does mathematics classroom teaching cultivate students’ core quality? What teaching processes and methods are adopted to ensure the implementation of core literacy? How to evaluate students to achieve the corresponding core quality? Based on the above thinking,this study combined with the Ub D theory to solve these problems put forward a new idea.Therefore,this study combines the Ub D theory with the content of "exponential function and logarithmic function" to conduct teaching design and practice research,Hope to provide some help for the teaching work of frontline teachers.In this paper,literature analysis is adopted to analyze the Ub D theory,unit teaching design,"exponential function and logarithmic function" and other aspects,so as to understand the research status and lay a foundation for the following research.Then questionnaire survey method,Then the questionnaire method,the interview method and the statistical analysis method were adopted,Understanding the current situation of teaching "exponential and logarithmic functions".Finally,experimental research method and statistical analysis method are adopted to verify the effectiveness of Ub D theory for students to learn "exponential function and logarithmic function".The thesis consists of seven chapters:The first chapter is an introduction,The background of this study is explained,the significance of teaching Ub D theory with "exponential and logarithmic functions" is analyzed,and the specific design of this study is introduced.The second chapter is a literature review,which compares the preparation of this paper,defines the core concepts of this paper,analyzes the status of domestic and international research on "Ub D" theory and "exponential and logarithmic functions",and explains the theoretical basis related to this paper.The third chapter is the investigation of the teaching status of "exponential function and logarithmic function".Firstly,questionnaire survey is adopted to survey the research objects.In order to better understand the learning status of students in "exponential function and logarithmic function" and find out the problems and difficulties of current students,test papers are prepared to test students,and finally,interview method is adopted to understand the teaching status of teachers.The fourth chapter is a detailed analysis of the "exponential function and logarithmic function" teaching content.Determine teaching content and teaching objectives of this chapter.The fifth chapter is the construction of instructional design framework based on Ub D theory.According to the instructional design framework of Ub D theory,the instructional design of "exponential function" and "logarithmic function" is formulated,taking "Exponential Function" and "Logarithm and its Operation" as examples.The sixth chapter is the research of teaching practice under Ub D theory,combining the content of "exponential function and logarithmic function" with Ub D theory.In practice,in the first grade,two classes with similar levels were selected as subjects.Among them,the experimental class uses the teaching design under the Ub D theory,while the control class uses the traditional teaching design.The results of the post-test scores showed that there was a significant difference between the scores of the two classes,and the mean score of the experimental class on the post-test was 5.4 points higher than the mean score of the control class on the post-test,which confirms the validity of the Ub D theory to some extent.Chapter seven is the conclusion and shortcomings of this paper.This paper mainly summarizes the whole research process.Due to the short teaching time and lack of teaching experience,there are still many shortcomings in this study.Therefore,I reflected on the problems existing over the course of the study,hoping to provide some reference for the follow-up research.
