一、指导思想与理论依据新教材更关注学生的经验与兴趣,通过现实生活中的生动素材引入新知,使抽象的数学知识具有丰富的现实背景,努力为学生的数学学习提供生动活泼主动求知的材料与环境。另外新教材以发展人文精神为宗旨,以提高学生的综合素质为目标,以贴近学生生活实际为导向,遵循学生的认知规律,由易到难,由浅入深,总把所要学习的知识渗透到特定的情境中,让学生入境生情,在身临其境的氛围中学习数学。二、教学背景分析 I. Guiding Ideology and Theoretical Basis The new teaching materials pay more attention to the students ’experiences and interests, introduce new knowledge through the vivid material in real life, make abstract mathematical knowledge rich in realistic background, and strive to provide vivid and active knowledge for students’ mathematics learning Materials and environment. In addition to the new textbook to develop the human spirit as the purpose, to improve the overall quality of students as the goal, in line with the actual student-oriented life, follow the cognitive rules of students, from easy to difficult, from shallow to deep, the total knowledge to be learned In specific situations, students are allowed to enter the country and learn math in an immersive atmosphere. Second, the teaching background analysis
