Integrated Teaching Design of Junior High School "Parallelograms" Unit Based on UbD Theory

Abstract

The "Mathematics Curriculum Standards for Compulsory Education (2022 Edition)" require "teachers to conduct overall teaching design for each unit to promote students' understanding of knowledge". The teaching design using UbD method, through three stages of "determining expected results", "seeking evaluation evidence", and "designing learning activities", can enable students to achieve true understanding and overcome the drawbacks of traditional education such as "indoctrination teaching" and "isolated teaching activities". Firstly, propose the design basis for the overall unit teaching design based on UbD theory; Secondly, conduct a textbook analysis of the "parallelogram" unit in middle school mathematics published by People's Education Press in terms of "textbook content" and "core content"; Again, based on the UbD theory, a unit based overall teaching design for "parallelogram" is carried out, and the first lesson of the first section, "Properties of Parallelograms", is taken as an example for lesson teaching design;  Finally, reflect on the teaching design of the "parallelogram" unit based on UbD theory.
