1设计说明1.1学情分析本节课针对中等偏上学习层次的学生而设计。“运用不同方式确定物体的位置”是图形与几何中要求达到灵活和综合运用层次的学习内容,确定“运动中的点的坐标”是学生普遍存在的一个难点。本设计以运动中的点的坐标为载体,在探索规律和图形变换中培养学生的空间想像能力、抽象思维能力、逻辑推理能力和创新能力,提升数学建模、数学运算、数据分析等数学素养,积累数学活动经验。1.2设计思想运动中的点,主要分为两类,一类是具有运动规律或排列规律的点,另一类是图形变换中的点。确定
1 Design Notes 1.1 Academic Analysis This lesson is designed for students with medium to high levels of learning. Determining the location of an object in different ways is a learning content that requires flexibility and comprehensive use in graphics and geometry. Determining the coordinates of a point in motion is a ubiquitous problem for students. This design uses the coordinates of the points in the movement as a carrier to cultivate students’ spatial imagination ability, abstract thinking ability, logical reasoning ability and innovation ability in the exploration of laws and graphic transformations to improve mathematical literacy in mathematical modeling, mathematical operation and data analysis , Accumulated experience in math activities. 1.2 Design Ideas Movement in the points, divided into two categories, one is the law of movement or arrangement of points, and the other is the point in the graphics transformation. determine
