《数学课程标准》提出:数学教学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,教师的数学教学首先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。在此,整理出本人在全市青年教师优质课比赛中所听到的《认识钟表》的教学片断,谈谈灵活再现生活情境,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 The Mathematics Curriculum Standard puts forward that mathematics teaching should let students experience the process of abstracting practical problems into mathematical models and explaining and applying them. Therefore, the teacher’s mathematics teaching must first guide students to pay attention to the phenomenon of life, and through the phenomenon to explore the existence of mathematical phenomena; secondly, we must think deeply about the mathematical nature after the phenomenon so as to comprehend the laws of mathematics and grasp the mathematical skills. Here, sorted out the teaching piece of “know the clock” heard by the young people in the city’s high-quality teachers’ class competition, talked about the flexible reproduction of life situations, made the knowledge more close to the students’ life, promoted the students’ understanding and accelerated the learning. And optimize to achieve effective learning and
