教学学具的运用并不是只有在物理和化学教学中,除此之外还有数学,特别是在小学数学中的运用。因为小学生往往只对身边所存在的事物熟悉,而不自知世界之外的事件,所以教师需要运用教学学具展开小学生的学习之窗,为学生展开另一项通往世界之窗,以让学生看到“世界”之外的事物。就学具的有效使用,及开展“世界之窗”开展了探讨。 Teaching the use of teaching tools is not only in physics and chemistry teaching, in addition to mathematics, especially in elementary mathematics. Because pupils tend to be familiar with what is around them and do not know the events outside the world, teachers need to use teaching tools to start the pupils’ window of learning and start another pupil’s window to the world Students see something other than “world”. Effective use of learning tools, and to carry out “Window of the World ” carried out discussions.
