"Compulsory Education Mathematics Curriculum Standards (2022 Edition)" (hereinafter referred to as "New Curriculum Standard") proposes the curriculum concept of "design that reflects the characteristics of structural characteristics" and "the overall analysis of the teaching content，Help students establish the essence of mathematics discipline、Teaching suggestions for the future learning that supports supportive and structured mathematical knowledge systems "。Under this concept，The new curriculum standard adjusts the arrangement and specific content of the curriculum。Curriculum content structured can properly form a whole，Avoid students from learning knowledge in isolation。Structural process analysis and refine the subject essence of learning content，helps to promote students' deep understanding and comprehensive grasp of knowledge。The staged characteristics of the structured results are also progressive in order to achieve learning、Spiral advanced creation may。

Unit design is one of the key factors that reflect the structure of the curriculum。Specific to practice，Find the "Leader" for the unit design，and use this as the core organization unit learning content，Unit content and subject knowledge、Establishing logicized in the real world、Concentration and integrated structure。The concept is the actual leader、Augmented concepts of experience and subject essence，It has the essence of knowledge、Disciplinary discipline structure、The characteristics of other disciplines or real worlds bet365 live casino games associated，It has important value for design structured teaching units。

Ability is conducive to the integration of concepts to gather into learning logic。The organization of the curriculum has many ways，Follow the discipline development、Student cognitive or practical experience，Different organizational philosophy constitutes a curriculum structure of different samples。The concept can integrate the concepts and factors in all aspects，Integrated textbook unit and experience unit，Then it becomes a learning logic that promotes students' understanding and migration，Make the course content "visible"。For example，Human Education Edition Primary School Mathematics "Large Cognition" Unit，Teaching recommendations up to 12 lessons，But by finishing、Analysis and fusion，It can be aggregated into three rural concepts for understanding and expression，that is, 1 is the basic counting unit，Natural numbers use decimal count，How many one can be used in any number、Ten、Bai et al. Express。The "Large Cognition" unit of the logical logic of the concept，"In -depth coverage of a small amount of theme to replace the surface coverage of all themes in the subject field，These few themes make the key concepts in the discipline understand "。It not only reflects the nature of the natural number，It is also in line with the law of children's cognition，It is conducive to the basic composition of students to understand the number of nature、The relationship between numbers and numbers, and read and write rules。

Abnormal concepts are conducive to reflecting the essence of the consistency sequence。The main learning theme of the primary school mathematics course，It is arranged in three sections bet365 best casino games in the form of spiral ascension，Therefore, you need to use one or more core concepts as the lead，penetrate the entire theme，Reflect the common essence，Composition with long -term significance、Study task sequence of consistent features。For example，Cognition and calculation，You can use the concept of "how many counting units" as the leader，Make integer、decimal、The understanding of scores constitutes the same task sequence。Specifically，The first school section，Learning within 10,000 to allow students to understand the meaning of "digital"，Understand the number of numbers in different digits，3003_3024。Second learning paragraph，The focus is to learn the decimal counting method and score unit，Experience integer、decimal、The scores are all expressing the expression of "how many units"。Third Study Paragraph，Through induction、Summary，Complete the relationship between them。

Ability concepts are conducive to connecting units to form a curriculum overall。The concept can explain and predict the core of discipline knowledge within a large range of things and phenomena，You can even be between units or even other discipline concepts、A close relationship occurs between knowledge，Promoting knowledge association。For example，The content of the course of the "Graph Movement" of the Elementary Education Edition of the Education Edition is arranged in three sections，General teaching，Students often think that learning "axisymmetric graphics" is to draw the other half of the symmetrical shaft，It has nothing to do with "exercise"，Translation、Rotating is to draw the position after exercise，The relationship between the three is blurred，Understand Bet365 app download "Failure"。If in the "Movement of Graphics"，Use "What changed、What is the same and how to change "to lead these contents，can make students understand the relationship between the three movements better，The units of three sections of segments are connected into a integrated "large unit"。

　Design structured teaching solution with the use of concepts

The development of the new curriculum standard provides reliable standards and basis for the development of academic requirements for the development of reverse design，The stage of the textbook based on the characteristics of the student's cognition，Leading the concept of concept becomes urgent demand。The following "rectangular and square" units with the third grade of primary school mathematics，Several modes that have been formed by the unit design around the concept，Show the framework and technology of the design -oriented unit design under the perspective of the perspective of the perspective。

First，Determine the expected results of learning。First，Determine with reference target。That is, find out the target content or words related to this unit from the school goal of the new curriculum standard。Curriculum target corresponding to this unit is: Knowing common plane graphics，Surveying the measurement process of the circumference of the plane graphics，Calculation method of exploring the rectangular perimeter and area。Next，Understand the concept。Unit design，Except for teachers, they need to use the concepts to organize knowledge，It is also necessary to let students understand the corresponding unit concepts，In order to deeply understand the knowledge and lay the foundation for migration and application。The common concepts of this unit can be summarized bet365 best casino games as three points: experienced the essence of measurement is the accumulation of the unit; understanding the perimeter is a further portrayal of the graphic characteristics;，To obtain the formula and specific method of calculating the perimeter。To promote students' understanding and use of components，This unit establishes three basic problems: which part of the circumference of the graphic refers to? How can the perimeter be measured?，Clarify the "Four Base" goals。New curriculum standards according to the level of development of students' core literacy，Combined with course content，Developed academic quality standards。So，According to academic requirements and students' pre -experience，Formulating basic knowledge and skill goals，Development requirements for basic ideological methods and activity experience。

2，Clear and appropriate evaluation evidence。Under the perspective of the perspective of the perspective, the design requires teachers to think like "Evaluations"，Think about how to determine whether the students have the "four bases" and understand the concept。Based on this，This unit except unit volume、Workbook、Self -reflection，also designed a expressive task to evaluate the level of conceptual understanding of students: in the rectangular garden，Design a small road from the pavilion to the fish pond，Divide the garden into two parts，The upper part of the left is converted into "Taoyuan"，The upper part of the left is converted into "Taoyuan"。Taoyuan one week planting peach tree，Li Yuan planted Li Shu a week，The interval between the trees is the same，The total number of peach trees and Li Shu is the same，means "Tao Li Man Tianxia"。Please design one or more solutions and suggestions for students。bet365 live casino games Expressive tasks are authentic、Features of complexity and openness，Make students' performance results multi -dimensional、Diverse features，The level of performance also has a richer level。To better determine the level of understanding of students，Need to use some theories and basis，Describe the evaluation of different response levels，For teachers to judge students' tasks to complete。

third，Learning tasks of the planning unit。Under the guidance of the unit of the unit，Combined with the content of the textbooks and academic analysis to carry out reorganization，Design the learning of the "rectangular and square" unit into an advanced process。The first stage focuses on understanding the concept of week long，That is the accumulation and portrayal of a weekly length of graphics or things。Follow the special relationship between the edge and the edge in the second stage，The relationship between the metamorphosis attribute and the graphic elements，Therefore, the calculation formula of common graphics is reasonable。Third stage through migration, use and evaluation activity，Deeply understand the essence and general significance of the circumstances of the figure。

fourth，Check the consistency of the design of the unit。This structured unit design，With the concept of "reverse design"，The "top -down" design program，I also chose an effective organizer -concept。But in the specific operation process，It should also carry out the "consistency" inspection procedures of the "consistency" of the course。The so -called curriculum consistency，is the goal of the course、Teaching、Evaluation matches each other，that is, after completing the unit design，Bet365 app download find the corresponding "evaluation basis"，and find the corresponding detail from the expected results such as "Four Base Targets", "Understanding the Concepts" and "Reference target"，so that specific learning tasks and evaluation evidence、The expected results remain highly matched，Reached a strong structured unit design。
