在教学实践中,我认为可以通过创设问题情境来优化口算教学,从而激发学生的学习兴趣,提高学生的口算能力。笔者以《两三位数乘一位数、整十数的口算》一课为例,分析我的几点具体做法:一、创设课前问题情境,激发学生学习口算的兴趣;二、创设生活化问题情境,让口算教学源于生活;三、创设合作探究问题情境,实现口算方法多样性;四、创设游戏化问题情境,实现口算教学学以致用。
In teaching practice, I think that we can optimize the oral teaching by creating problem situations so as to arouse students 'interest in learning and improve students' ability to communicate. The author takes the lesson of “Number One and Two Digits by One Digit and Number Ten Mouth Counting” as an example to analyze some of my specific practices: First, create situations of pre-class questions and stimulate students' interest in learning oral arithmetic; Second, create life Third, create cooperation to explore the situation of the problem, to achieve the diversity of the oral arithmetic; Fourth, the creation of the game of the problem context, to achieve the purpose of oral teaching.
