“方向感”带你轻松辨方向——三下“认识东南西北”一课的教学与所得

Identifying Directions Easily through the Sense of Direction:Teaching Reflections on the Lesson "Learning about Directions" for the Second Semester of Grade Three

"路痴"是与生俱来的吗?科学家们对小老鼠脑中负责辨认方向的细胞进行研究,然后推知人类的方向感是与生俱来的,但会随着后天空间经验的增多而不断完善。这样,对许多人而言,与其说他们没有方向感,不如说是方向感没有被很好地开发、利用。培养小学生的方向感,对其今后的生活工作会带来很多便利。义务教育课程"图形与几何"中专门有一部分内容学习位置与方向。三年级下册《认识东南西北》则是让学生理性地、数学化地去认识东南西北,将生活积累的空间观念进行完善。培养学生的方向感,使他们在生活中轻松地去辨认方向。

To find out whether ＂having no sense of directions＂ is an inborn defect, scientists researched the cells responsible for i- dentifying directions in a little mouse＇s brain, and then inferred that people＇s sense of direction is inborn, but it will be improved with the accumulation of space experience during their growth. For many people, we would rather say their sense of direction has not been well developed and used than say they have no sense of direction. The cultivation of pupils＇ sense of direction will bring much convenience to their future life and work. There is a content specifically for position and direction learning in the compulsory course ＂Graphics and Geometry＂. The lesson ＂Learning about Directions＂ for the second semester of Grade Three is to improve pupils＇ accumulation of space concepts, and cultivate their sense of direction, so as to help them to identify directions easily.
