I have read many books, but I seldom write my own thoughts. This winter vacation, I read "Primary School Mathematics Research" edited by Zhang Diandi. In fact, this is not the first time to read this book, because director Huang Shengying originally recommended us to read this book. I have read it all before, but I have never read it completely from beginning to end. However, the book "Primary School Mathematics Research" is very good and worth reading by math teachers. It can improve the teaching level, and the most important thing is to pass on the most accurate mathematical ideas to students and benefit our students. The study of primary school mathematics takes the content of primary school mathematics as the research object, and analyzes, expands and perfects the important content of primary school mathematics from a lofty standpoint. For primary school mathematics teachers, learning and deeply understanding this knowledge will definitely promote and promote primary school mathematics teaching.
As a math teacher, I often encounter some difficult problems in teaching, and sometimes I have a little knowledge of the problems that I couldn't figure out in primary school, but this book is very accurate and scientific, and even simple questions tell the truth and convince people. Such as why natural numbers start from 0 instead of 1, why the smallest even number is 0 instead of 2, why the smallest digit is 1 instead of zero, and so on. In this book, I found the answers to the questions and arguments discussed by teachers, and understood the reasons, which really made people suddenly realize.
Because the study of primary school mathematics can profoundly explain the regularity of primary school mathematics. For example, the thinking method contained in primary school mathematics proposed in the first chapter allows us to critically deepen our grasp and understanding of primary school mathematics from a higher level. Mathematics is the proposition of "relationship", which further reveals the profound essence of primary school mathematics content. All mathematical problems exist in the relationship, which can be said to have a guiding and programmatic role in the study of mathematical knowledge in primary schools.
Therefore, this book has become my mentor and assistant in my work. I will open the questions I don't understand, and I will read them carefully when I have time. From this book, I not only understand the development and history of pi, the essence of translation and rotation, and the true meaning of equations in primary school mathematics, but also understand the profoundness of mathematics. As a math teacher, I should not only teach students the knowledge in books, but also understand the internal relationship of math knowledge. I really understand the content of the textbook thoroughly, so I feel that if I want to be an excellent primary school math teacher, I have to keep charging, learn my own math professional knowledge and improve my professional level. So I sincerely recommend this book to our math teacher.
