通过《中小学数学》看到同行们把几何画板应用于教学中起到了良好的效果,笔者在给学生讲解一道求两线段之和最小值问题时,也尝试着用这种信息技术手段作了辅助教学,并对解决这个问题的教学提出了一些浅陋的看法,望各位同行不吝赐教.

Through the “primary and secondary mathematics” to see the counterparts to the geometric drawing board used in teaching has played a good effect, the author explain to students a minimum of two-line and the minimum problem, but also try to use this information technology has assisted Teaching, and put forward some humble opinions on the teaching of solving this problem, hope all of you have generous comments.
