通过对师生简算的调查表明,学生在实际应用中未能很好地运用简算知识解决问题,究其原因是教师在教学中忽视了对学生简算意识的培养。因此,简算教学应在发展学生简算技能的同时,帮助学生形成简算意识,让学生灵活、合理地选择运算途径,并逐步形成和不断强化这种思维方式,从而提高计算能力。一、抓好口算,练好口算基本功,为简算打好基础口算不仅是笔算是基础,而且是简算教学的主要重要组成部分,因此要学会简算,提高计算速度,就要从加强口算入手,让学生练好口算基本功。
According to the simple survey of teachers and students, it shows that students can not use simple knowledge to solve the problem well in practice. The reason is that teachers neglect to cultivate students’ simple-mindedness in their teaching. Therefore, the simple teaching should not only develop students’ basic abilities, but also help students form a simple sense of consciousness so that students can choose the ways of calculation flexibly and rationally, and gradually form and continuously strengthen this way of thinking so as to improve their calculating abilities. First, do a good job, do a good job accounting basic skills, lay a good foundation for simple calculation Not only is the basis of pen calculations, but also a simple teaching an important part of the important, so to learn simple calculations, to speed up the calculation, it is necessary to strengthen the calculation Start, let students practice good oral basic skills.
