| The"Compulsory Education Mathematics Curriculum Standard(2011)Edition"pointed out that students'understanding of knowledge and the connection between mathematical knowledge is the primary task of mathematics teaching.At present,in order to adapt to the cognitive abilities of students at various stages,the layout of junior high school mathematics textbooks has the characteristics of decentralization and spiraling,but this method may cause the fragmentation of the knowledge accepted by the students,which is not conducive to the formation of a complete knowledge structure.As an important course type of unit teaching,unit initial course teaching has the macro-leading role of allowing students to see"forest"and"trees"later,guiding students to independently construct a knowledge framework and develop thinking skills,and form a scientific cognitive structure,have the role of command unit.However,in actual teaching,the unit starting class has not been paid much attention to compared with the specific class hours with obvious teaching effect,so that its advantages have not been highlighted.Therefore,the unit starting class based on structured teaching brings new ideas to the teaching of unit starting class.This article mainly combines the current teaching situation of the unit starting class,and conducts research on the unit starting class teaching based on structured teaching.First,through studying the literature,the meaning of structured teaching is researched.It also studies and studies the theoretical foundation of the unit starting class in advance organizer theory,system theory,and constructivist theory,and studies the teaching practice of the unit starting class in recent years.Secondly,a questionnaire survey was conducted on the teaching status of the unit introductory class for teachers in two schools in a certain area to understand the development of the unit introductory class.Finally,based on the relevant questions reflected in the questionnaire and combined with theoretical foundations,the research is carried out,combined with the structured teaching concept,and it is proposed that the teaching goal of the unit starting class should be based on the construction of the unit knowledge structure,and the depth of the specific content of the control unit should be reasonably controlled.The constructivism theory is different from the passive acceptance learning in the past.It guides students to form a mathematical thinking structure and a structured thinking ability in the unit starting class,based on the cultivation of lifelong learning ability.Under the guidance of the system view theory,the chapters are integrated,breaking through the limitations of chapters,and focusing on large units to guide students to independently construct knowledge frameworks and structures.Secondly,it proposes a structured instructional design method for the unit starting courses of the two categories of knowledge at the beginning of the module and knowledge under the node.Among them,the knowledge of the module starting point refers to the concepts,graphics,and algorithms that students are exposed to for the first time.The primary task of the unit introductory course for this type of knowledge is to guide students to establish a framework for studying such issues based on the relevant theories of constructivism,and to be the first organizer material for follow-up research,so as to play a demonstrative and leading role,and then achieve the overall construction of knowledge,The purpose of thinking development coherence.For the knowledge under the node,it is based on the knowledge with hierarchical relationship pointed out by the system view theory.For the unit initial course teaching of the knowledge under the node,the teaching of the unit of the knowledge under the node should focus on guiding the students to connect and expand from the perspective of the knowledge connection within the system to establish a hierarchy.,And the knowledge structure of organic connections between levels. |
