Research On The Instructional Design Of "Number Sequence" Based On "Understanding By Design"

In view of the phenomenon of fragmentation of students' knowledge,the new curriculum standard proposes to "grasp the teaching content as a whole",and emphasizes that this is also the main means of "promoting the continuity and stage development of mathematics core literacy".In order to realize the overall grasp of teaching content,the author carried out a research based on "number sequence" of "Understanding by Design".The author aims to explore the unit design under the perspective of the theory of The Contrary Course Design.This study mainly discusses three issues :(1)the teaching design procedure based on "Understanding by Design";(2)specific teaching design cases based on "Understanding by Design";(3)teaching strategies based on "Understanding by Design".The research adopts several scientific methods,including literature research,questionnaires,observations,interview,and case studies.Firstly,establish the framework and template of unit design by exploring specific procedure in teaching design based on "Understanding by Design".Secondly,based on current situation analysis for math teaching and the content of “number sequence” in senior high school,study "number sequence" in unit design in terms of template mentioned above,and form a demonstration case on the basis of practice;Finally,make summaries and reflections upon the teaching design and acquire the teaching strategies of the mode,thus providing more teaching design experience to promote students' understanding.The conclusions consists of two parts: firstly,the steps of teaching design procedures to "Understanding by Design" are: analysis of mathematical content → analysis of learning situation → design of teaching objectives → design of teaching evaluation →determination of teaching strategies → specific design of teaching process.From which,the teaching design program table is acquired.Secondly,according to the gain and loss analysis of teaching cases,the teaching strategies to "Understanding by Design" are as follows:(1)Confirm the main problems in the unit,and help students to establish learning expectations;(2)The evaluation design need precede the teaching design,improve teaching pertinence;(3)Help students choose information and train basic methods;(4)Help students to organize information and clarify content logic;(5)Help students integrate information,and promote meaningful learning;(6)guide students to reflect and Improve the quality of thinking.
