“解决问题”教学版块是人教版《义务教育教科书·数学》的一个亮点。在这部分内容的教学中,设计了“阅读理解”“分析解答”“回顾反思”三个教学环节。针对低年级学生的学习特点,提供了以下“解决问题”的初级思维模型:“知道了什么——怎样解答——解答正确吗”。纵观一、二年级四册教材,解决问题的新课例题达到32个,除了最基本的加减乘除外,还涵盖了几何、时间、重量等生活中的实际问题。因此,优化小学数学“解决问题”课型的教学环 “Problem solving ” teaching section is a highlight of the PEP “compulsory education textbook mathematics”. In this part of the content of teaching, designed the “reading comprehension ” “analytical solution ” “retrospective reflection ” three teaching links. For the learning characteristics of lower grade students, the following primary thinking model of “problem solving” is provided: “know what - how to answer - correct answer ”. Throughout the first two and four volumes of textbooks, the new curriculum to solve the problem reached 32, in addition to the most basic addition and subtraction multiplication and addition, but also covers the geometry, time, weight and other practical problems in life. Therefore, optimizing the primary school mathematics “problem-solving ” class teaching ring
