在小学数学应用题教学中,分数应用题教学是其中的重点,又是一个难点,如果对这部分知识传授得不具体,就会影响学生的逻辑思维能力和解题能力。在教学中,我发现有少部分教师讲授这类应用题时不能很好地给学生讲清其中的数量与份数的关系,就用列方程的方法讲解倒推出其中的式子,这样当然能得出算式,但不能使学生正确掌握列式的方法。这种方法是不妥的,它违背了教学的原则,忽略了根据题意正确列式这种逻辑思维能力的培养。
In elementary mathematics application teaching, the teaching of fractional application problem is one of the key points, but also a difficult point. If this part of knowledge is not taught concretely, it will affect students' ability of logical thinking and problem solving. In teaching, I found that when a small number of teachers teach such applications, they can not explain the relationship between quantity and number of copies well, Get the formula, but can not make students correct grasp of the column method. This method is inappropriate, contrary to the teaching principle, ignoring the cultivation of logical thinking ability based on the correct formulation of the questions.
