Research On Unit Teaching Design Based On Core Accomplishment Of Mathematics

With the continuous deepening of the new curriculum reform,people pay more and more attention to the integrity of mathematics teaching and the cultivation of students' core literacy.The unit teaching design based on math core literacy has gradually become a "hot spot" for development.As a direct practitioner of the new curriculum and the concept of "new curriculum standard",front-line teachers should expand their teaching horizons and break away from the preparation of lessons in one section as soon as possible,and explore "what to teach and how to teach" with new concepts.An eternal topic of teacher teaching.At the same time,the plane vector is not only the core knowledge of high school mathematics,but also the important content of the high school students compulsory,the college entrance examination must be tested,but due to the instrumental characteristics of the plane vector knowledge,in the process of plane vector teaching,heavy application,light concept The phenomenon is widespread,which causes high school students to generally only perform mechanical algebraic operations,unable to grasp the deep geometric content of plane vectors,thus losing interest in mathematics learning,seriously hindering the development of students' core literacy.In view of this,the author determined to use "plane vector and its application" as an example to develop a unit teaching design based on mathematical core literacy.This study mainly discusses the following two questions:(1)Combining the current situation of planar vector teaching,how to systematically design the unit of "plane vector and its application" based on mathematical core literacy?(2)By comparing traditional time-based instructional design,what are the specific advantages of unit-based instructional design based on mathematical core literacy in teaching practice?This study adopts the literature method,questionnaire survey method and interview method.Firstly,based on a large amount of literature,the author summarizes the related research on math core literacy and unit teaching design.Secondly,through the questionnaire survey,the current teaching situation of high school plane vector is analyzed;Finally,combined with the teaching practice,the unit teaching design based on mathematical core literacy is applied to the "plane vector and its application",and it iswilling to provide some reference and reference for the deep development of the new curriculum reform.This study has two conclusions: First,based on the core literacy of mathematics,the research ideas of unit teaching design for "plane vector and its application" are:determining unit teaching content ? unit teaching content analysis ? unit learning condition analysis ? unit teaching goal analysis ?Unit teaching strategy analysis?Unit teaching time design?Unit teaching implementation and its effect analysis.Secondly,compared with traditional teaching design,the unit teaching design based on math core literacy has the following advantages: First,from the teaching content It is understood that the teaching unit based on the mathematics core literacy unit teaching design is the teaching content system that the teacher reorganizes and optimizes the content of the textbook according to the requirements of the new curriculum standard and the actual teaching needs,which is in line with the integrity and continuity characteristics of mathematics knowledge.From the perspective of teaching objectives,the mathematics core literacy unit teaching design pays attention to the achievement of high-level goals(such as mathematical essence,mathematical thinking and mathematical core literacy)while paying attention to knowledge and skills.From the perspective of teaching strategy,based on mathematics Core literacy unit teaching design The creation of easy-to-student initiative and independent learning situations.
