口算是计算的重要组成部分,也是笔算、估算和简算的基础,培养小学生快速、准确的口算能力必有助于他们今后的数学学习。然而,口算练习枯燥乏味,学生一般不喜欢主动练习,课堂教学中也没有足够的练习时间。针对这些问题,我设计制作了网络版《口算大师》软件,采用多种激励措施,引入游戏形式,让学生提升学习兴趣、提高练习效率,并减轻学生、家长和老师的负担。本文介绍了这个软件及其设计理念和应用实践的收获。 Mouth calculation is an important part of calculation, but also the basis of calculation, estimation and calculation. Training pupils’ quick and accurate calculation ability will help them to study mathematics in the future. However, oral exercises are boring, students generally do not like active practice, classroom teaching, there is not enough practice time. In response to these questions, I designed and produced the online version of “Mouth Masters” software, introduced various forms of encouragement and introduced game forms to enhance students’ interest in learning, improve practice efficiency and ease the burden on students, parents and teachers. This article describes the software and its design concepts and application of the harvest.
