Based On The UbD Theory Of Linear Function Teaching Practice Research

As proposed in the 2022 Edition of Mathematics Curriculum Standards,mathematics curriculum should cultivate students’ core qualities,and the cultivation concept of core qualities has become an important concept leading the development of classroom teaching and teachers’ teaching design.Therefore,scientific and efficient instructional design can not only improve the quality and efficiency of teaching,but also promote the development of scientific teaching and professional teachers.This paper studies the instructional Design based on the theory of UbD(Understanding by Design),reviews the unit instructional design strategies under the theory of UbD by referring to literature,and takes the lesson of the image and property of primary function in Chapter 19 of junior middle School Mathematics in the Human Education Edition as an example for practical verification.The author carried out a functional image and property investigation among the eighth grade teachers and students of w Middle School,where he taught.Through literature review,teaching practice comparison,pre-teaching and after-learning testing of students,result investigation and analysis,interviews with teachers and students and other practical actions,the author carried out the research.After teaching through traditional instructional design and UbD theory-based instructional design respectively,two classes at the same level are compared and analyzed the students’ mastery of knowledge,so as to find out the existing and exposed problems in the teaching process of teachers and students in the learning process,respectively from the perspective of teaching and learning,analyze the results and get reasonable suggestions.Through the comparative analysis of the classroom performance of the experimental class and the control class and the completion of the pre-test and post-test questions of the students,combined with the interview results,the following findings can be made: First,the classroom atmosphere under the UbD teaching model is more active than that in the traditional classroom according to the actual situation of the classroom,and the students have higher enthusiasm and participation.Students change from passive to active way to explore new knowledge,through independent thinking and exploration,the image and nature of the first function to build a knowledge framework,understand the essence of the image,the application of knowledge is more flexible;Second,through a comprehensive analysis of the interview records of three front-line teachers,UbD teaching model can guide teachers to start from the teaching objectives,reverse design the teaching process,and appropriately increase the proportion of formative evaluation in the evaluation.Teachers’ time allocation in class will also be transformed from focusing on practice to focusing on understanding,and guide students to sublimate on the basis of in-depth understanding of concepts.Complete the exploration and recreation of knowledge.3.Problems found in the research: students’ vague concept of the movement change of functions,weak awareness of the combination of number and form,lack of understanding of the connection and distinction between knowledge,lack of reading ability,which leads to the inability to obtain topic information in practical word problems,and the change of thinking set from intuitive to abstract requires time to adapt.
