Based On UbD Model Reverse Instructional Design Of High School Function Monotone Unit

The new curriculum standard puts forward the idea of unit teaching with three main lines of content as the theme,and emphasizes the need to grasp the teaching content as a whole as an important means to promote the development of mathematics core literacy.Based on this,the author carried out the research on the unit instructional design of "functional monotonicity" under the guidance of "UbD" model theory with "functional monotonicity" as the main line.The purpose is to discuss the unit instructional design of reverse teaching,specifically to discuss three questions:(1)The instructional design based on the pattern of "UbD" program;(2)Instructional design case of function monotonicity based on "UbD" model;(3)Teaching strategies based on "UbD" model.This study adopts literature research method,questionnaire survey method,classroom observation method,interview survey method and case study method.Firstly Through literature search,based on "UbD" model,specific steps of reverse instructional design are discussed,and corresponding unit design template and framework are formed;Secondly,by analyzing the current situation of function concept teaching and the content of "function monotonicity" unit with "function monotonicity" as the main line,and combining with the specific steps of unit design template,the unit teaching design of "function monotonicity" is studied and a demonstration case is formed which is based on practice;Finally,this paper summarizes and reflects on the teaching design,and obtains the mathematics teaching strategy based on "UbD" model of reverse teaching,hoping to provide some teaching design experience.The conclusions of this study are mainly composed of two parts:First,the instructional design program based on "UbD" model is as follows: analysis of instructional content,design of teaching objectives,analysis of learning situation,design of instructional evaluation,analysis of instructional strategies,design of instructional process,and generation of corresponding program framework table of instructional design;Secondly,through the analysis of the gain and loss of the specific design case of the functional monotonicity unit,the mathematical teaching strategy that is beneficial to the reverse teaching of "UbD" model is obtained as follows:(1)determine the main problems of the unit and set learning expectations;(2)teaching evaluation precedes instructional design to improve teaching pertinence;(3)help students learn how to choose information and summarize basic methods;(4)help students learn how to organize information and make clear the content structure;(5)help students integrate information to promote meaningful learning;(6)help students learn to reflect effectively and improve their math literacy.
