关于理与法结合学好小学计算课的思考

Reflections on the Combination of Comput ational Principle and Algorithm to Learn Computational Course in Primary School

目前,理解算理与掌握算法成为计算教学的首要任务,为了完成这两个教学目标,很多教师都在不断的努力着,但是在过程中出现了重法轻理或者重理轻法的现象。重理轻法使得学生在学习计算的时候只明白算理,也大致清楚计算的方法,但是由于计算方法的练习相对少,所以在计算能力上就会相对薄弱,经常会出现算错或不会算的现象。重法轻理则是学生知道计算的方法,但是随着学习的知识越来越多,很多的方法类似,学生在记忆过程中出现了混淆,因此在学习计算时出现了方法运用混乱的现象,又不能及时纠正自己的问题,阻碍了学习计算课的兴趣。因此在计算课的教学中既要重视算理,也要关注算法的掌握,只要两者结合起来,学生既明理又懂法才能游刃有余地"游走"在计算课中。所以计算课的学习算理是根本,算法是学生必须掌握的底线。学生通过理解算理,形成计算方法,然后在实践中辨理证法,才能加深对计算内容的认识,学好小学计算课。

At present,understanding calculation theory and mastering algorithm have become the primary task of calculate teaching.In order to accomplish these two teaching goals,Many teachers are constantly working hard,but in the process there has been a neglect computational theory or contempt for calculation methods phenomenon.The emphasis on calculation theory and the neglect of calculation methods allow students when learning to calculate,only understand the reason,and the method of calculation is generally clear.However,due to the relatively little practice of calculation methods,So it's relatively weak in computing power,computational errors or can not calculate often occur.Attaching importance to the calculation method and belittling the calculation theory makes Students know how to calculate,but with more and more knowledge,many methods are similar.In the process of memorizing,students are confused,so there is confusion in the use of methods in learning calculation.And can not correct their own problems in time,hindered the interest of learning computing class.Therefore,in the teaching of computing class,we should not only pay attention to the calculation of the rationale,but also pay attention to the grasp of the algorithm,as long as the combination of the two,students are both calculation theory and understanding of the calculation methods can be easily"Very good learning"in computing class.So the learning of calculation theory is fundamental,algorithm is the bottom line that students must master.Students can deepen their understanding of the content of calculation by understanding the theory of calculation,forming a calculation method,and thenIn practice,it is necessary to justify the calculation theory by proving the correctness of the calculation method,so as to deepen the understanding of the calculation content and learn the elementary school calculation course well.
