“综合与实践”作为一个独立的部分呈现在数学教材之中,是新课程改革的一个亮点,而且与“数与代数”、“图形与几何”、“统计与概率”并列为数学学习内容的四大板块。它在内容上既不是新知识,也不是对以前知识的复习,它注重培养学生的数学意识、数学实践与创新能力。作为四大学习内容之一来呈现,是“新”的,“综合与实践”又没有新知识的学习内容,它又不是“新”的,致使许多教师在教学理念上、教学形式与方法上、内容处理上、教学组织安排上有所困 As an independent part, “synthesis and practice” is presented in mathematics textbooks, which is a bright spot in the reform of the new curriculum. And it is closely related to statistics and probability of “number and algebra ”, “figure and geometry ”Tied for the mathematics learning content of the four plates. It is neither a new knowledge content nor a review of previous knowledge, it focuses on cultivating students’ mathematical awareness, mathematical practice and innovative ability. As one of the four major contents of study, it is a new content, which is not “new” but also “new” and “integrated and practicable.” As a result, many teachers, in their teaching philosophy , Teaching methods and methods, content processing, teaching organization and arrangements on the difficulties
