上一学年,银川城区文教科数学教研组,因地制宜,积极开展教研活动.他们的主要做法是——专题探讨,改进口算教学针对目前教学中普遍存在的运算不灵活,计算过程烦琐、速度慢、准确率低等情况,他们开展了“培养学生口算能力”的专题研究.他们首先要求各学校组织数学教师认真学习教学大纲,明确口算 In the previous academic year, the Yinchuan Urban Arts and Mathematics Mathematics Teaching and Research Section actively carried out teaching and research activities according to local conditions. Their main approach was to discuss the topic and improve the teaching of oral arithmetic. The computational process is inflexible, slow and accurate. In the case of low rates, they conducted a special study on “cultivating students’ ability to calculate oral calculations.” They first asked schools to organize mathematics teachers to seriously study the teaching syllabus and make clear oral statements.
