Research On The Teaching Design And Practice Of "Basic Inequality" Based On "Teaching-Learning-Evaluation Consistency

"The consistency of teaching,learning,and evaluation" is an inherent demand in current curriculum teaching.Its teaching philosophy assists in the implementation of the new curriculum standards.As a preliminary knowledge for the transition from junior high school knowledge to senior high school knowledge,basic inequality content is an important foundation for the proof of inequality in senior high school.It contains mathematical ideas such as the combination of numbers and forms,from special to general,and reduction.At the same time,basic inequality is also widely used in other disciplines and daily life.In the context of the current new curriculum reform and double reduction,it is difficult for teachers to implement "teaching learning evaluation consistency" in the classroom.Based on this,this study is based on the teaching concept of"teaching learning evaluation consistency" to study the content of basic inequalities in Senior One.Specifically,this study designs the following three research questions:What is the construction of an instructional design model based on "teaching learning evaluation consistency"?2.Based on the instructional design model,how to design instructional design for basic inequalities?How effective is the teaching practice based on the basic inequality teaching design of "teaching learning evaluation consistency"?In order to solve research problems,this study constructs a teaching design model framework based on the teaching concept of "teaching learning evaluation consistency",based on the theoretical foundations of reverse instructional design and mathematical problem solving teaching,starting with the core literacy of the mathematics discipline.Then,based on the framework of the "teaching learning evaluation consistency" instructional design model,instructional design is conducted for the two class hours of "proof of basic inequalities" and "application of basic inequalities".In order to test the effectiveness of the two class hour instructional design based on the teaching concept of "teaching learning evaluation consistency",namely,"proof of basic inequalities" and "application of basic inequalities",the author applied the instructional design of this study to teaching practice,and summarized the teaching effectiveness through teaching video analysis,student self-evaluation analysis,and teacher interview analysis to provide suggestions for frontline teachers.Based on the results of teaching practice analysis,this study draws the following conclusions:1.Design teaching based on the teaching concept of "consistency in teaching,learning,and evaluation" to effectively achieve the goals.Designing teaching based on the teaching concept of "consistency in teaching,learning,and evaluation" is conducive to improving students’ interest in learning and exerting their subjective initiative.Designing teaching based on the teaching concept of "consistency between teaching,learning,and evaluation" is conducive to implementing the teaching concept of evaluation in the new curriculum standard,giving play to the functions of evaluation such as guidance,feedback,motivation,improvement,and research.
