教学理念在“图形的认识”的教学中,体现“从生活抽象出图并应用于生活”的教学理念。图形的认识是低年级学习的基础,由开始的点、线段、角到后来的复杂的图形,学生的认知水平的提高不断深入,循序渐进。为此,在低年级的时候教师就要让学生感受到认识图形的方法,要重视从生活中抽象出图形的过程,还要反过来将图形及其特征应用到生活中去,才是最佳选择。《义务教育数学课程标准》中指出:教师应激发学生的学习积极性,向学生提供充分从事数学活动的机会,帮助他们在自主探索和合作交流的过程中 Teaching philosophy in the “understanding of the graphics ” teaching, embodies the “abstract from life graph and applied to life ” teaching philosophy. The understanding of graphics is the basis of the lower grades, from the beginning of the point, line, angle to the later complex graphics, the student’s cognitive level to deepen, step by step. For this reason, in the lower grades, teachers should let students feel the way to know the figure, pay attention to the process of abstracting the figure out of life, and in turn, apply the figure and its characteristics to life to be the best select. The standard of compulsory education mathematics curriculum states: teachers should stimulate their enthusiasm for learning and provide students with the opportunity to fully engage in math activities to help them in their own exploration and cooperation and exchange of information
