"Official Document Mathematics" is a mathematical training model implemented in Japan after long-term practice. Its advantage lies in cultivating students' self-study ability, forming good study habits, and improving unit study time efficiency and calculation accuracy. At the beginning of the school year, we introduced the advanced teaching method of "official document mathematics" in our teaching, so that students can keep training for 15-20 minutes every day and persevere. A considerable number of students in grade three or four have reached the level of grade one or two in junior high school.
Four years' practice has proved that students' autonomous learning ability and enthusiasm for learning mathematics have been improved, bad study habits have been corrected, students' "diligence" and "intelligence" have been organically combined, and each student's potential ability has been excavated and developed to the maximum extent.
The origin of official document mathematics;
1954, Mr. Gong Wengong, a senior high school math teacher at that time (the founder of Japan Official Document Education Research Association) wrote a set of math problem sets for his eldest son in the second grade of primary school, which is the origin of official document learning method. Its effect can not only improve students' mathematics ability, but also cultivate students' self-study ability and lay a good learning foundation.
Since then, the document learning method has been popularized in 30 countries around the world as an effective way to develop students' ability, and more than 2 million students are using the document learning method to study. Since the publication of the official mathematics textbook, it has been constantly absorbing experience from practical application and constantly revising, striving to improve the textbook in terms of the number of questions, order and examples, so as to achieve the best learning effect.
