The Research On Mathematics Teaching Instruction Unit Under PBL Teaching Mode In High School

Since the implementation of the new curriculum standards,teaching design has paid more attention to the process of students ’ learning,emphasized the construction of students ’overall knowledge,and encouraged students to actively participate in the learning process and acquire knowledge independently.Unit teaching takes knowledge points as the core,integrates relevant knowledge and skills,and forms a complete teaching unit,which can better promote students ’ overall understanding of knowledge.PBL teaching mode enables students to master necessary knowledge,skills and experience through independent learning,cooperative learning and inquiry learning in the process of solving problems.It can effectively organize problems many times and encourage students to think actively and explore independently.Therefore,this paper will study the teaching design of mathematics unit based on PBL teaching mode.Firstly,based on the relevant literature,the related concepts and theoretical basis are understood.Secondly,the current situation of unit teaching design is investigated and analyzed,aiming to find out some problems existing in unit teaching,so as to better carry out teaching design guided by PBL theory.Then,the integration of PBL teaching mode and unit teaching is studied.Finally,combined with the problems found in the survey,based on the PBL teaching mode,the teaching design is carried out with the isometric sequence as an example,and the teaching design is applied to the actual teaching.The learning situation of the experimental class and the control class was tested and analyzed through the test paper.Through practical test,the following conclusions are drawn : the teaching design of high school mathematics unit under PBL teaching mode is helpful to improve the effect of classroom teaching.
