新课程指出,学生是学习的主体。我们要提高小学数学的有效性,就要首先关注好学生,关注他们每一个学习过程中的细节,不断反思,不断改进。其次,我们要精心处理好教材,在兼顾知识体系的同时,更要促成知识的教育形态的形成,即知识是以学生易于接受的形态呈现的。同时,教师要在教学前下足工夫,即要从“精致备课”中求“轻负高质”。细致一:在课件的运用中,可以体现细致。很多教师经常出现这样的问题——雁过无痕。例如,上“两步计算应用题”一课时,经过师生的共同整理,师在大屏幕上逐一出示了三道题,分别让学生尝试解答,并一一加以反馈,最后引导学生对三道题加以比较。
The new curriculum points out that students are the main body of learning. If we want to improve the effectiveness of primary school mathematics, we must first pay close attention to the students, pay attention to the details of each of them in the learning process, constantly reflect on and continuously improve. Secondly, we must carefully handle the teaching materials, while taking into account the knowledge system, but also to promote the formation of the educational form of knowledge, that is, knowledge is presented in a form acceptable to students. At the same time, teachers should make the necessary preparations before teaching, that is, from the “exquisite lesson preparation” in the “light negative high quality.” A detailed one: the use of courseware, you can reflect the meticulous. Many teachers often have such a problem - goose no trace. For example, on the course of “Two-Step Calculation of Application Problems”, after a teacher-student collation, the teacher showed three questions one by one on the big screen, each of which allows the students to try to answer them one by one and feedback them one by one to guide the students Three questions to be compared.
