一九八六年秋,我用课程教材研究所小学数学教材研究实验组编的五年制小学课本《数学》第一册进行了教改实验,为了搞好实验,达到减轻学生过重负担,提高教学质量的目的,我们根据教学大纲的要求及我校的具体情况,集中研究了几个课题,其中一个就是:如何提高学生的口算能力。 我班有学生52人,其中8岁半以上21人,5～6岁半的31人,19人未上过幼儿园。因此学生的计算能力特别是口算能力是比较差的。20以内加减法的口算不仅是笔算的基础,也是小学实验教材第一册的主要内容,这部分内容学得如何,对学生日后计算能力的培养,起着重要的影响。为了使学生
In the autumn of 1986, I conducted a teaching reform experiment with the first volume of “Mathematics”, a five-year primary school textbook compiled by the Experimental Teaching Material Group for Primary School Mathematics in the Curriculum Materials Institute. In order to do a good job in experimenting, it is necessary to reduce the heavy burden on students and improve teaching According to the requirements of the syllabus and the specific conditions of our university, we focused on several topics, one of which is how to improve the students' ability to communicate effectively. There are 52 students in my class, of whom 21 are 8 years old and over, 31 are 5 ~ 6 years old and 19 have not attended kindergarten. Therefore, students' ability to calculate, especially the ability to account, is relatively poor. The calculation of the addition and subtraction within 20 is not only the basis of the calculation, but also the main content of the first volume of experimental teaching materials in elementary schools. How this part of learning can play an important role in the cultivation of students' computing abilities in the future. To make students
