《数学课程标准》提出:数学教学是要让学生亲身经历将实际问题抽象成数学模型并进行解释与应用的过程。因此,首先数学教学要引导学生关注生活现象,并透过现象探寻数学现象的存在;其次,要深入思考现象之后的数学本质,从而领悟数学规律、掌握数学本领。现就全县骨干教师优质课汇报活动中的《认识钟表》教学片段,谈谈如何灵活再现生活情境,让知识更加贴近学生的生活,促进学生的领悟,加速学习的深入和优化,以实现有效学习和高效课堂的教学理想。
The Mathematics Curriculum Standard puts forward that mathematics teaching is to make students experience the process of abstracting practical problems into mathematical models and explaining and applying them. Therefore, first of all, mathematics teaching should guide students to pay attention to the phenomena of life and explore the existence of mathematical phenomena through phenomena. Secondly, we should think deeply about the mathematical nature after phenomena so as to comprehend the laws of mathematics and grasp the mathematical skills. Now on the county’s backbone teacher quality class report activities in the “cognitive watch” teaching fragment, talk about how to reproduce the flexibility of life situations, so that knowledge closer to the student life, to promote students’ understanding and accelerate the learning in-depth and optimization in order to achieve effective Learning and efficient classroom teaching ideals.
