《数学课程标准》明确指出:要使学生“初步学会从数学的角度发现问题和提出问题,综合运用数学知识解决简单的实际问题,增强应用意识,提高实践能力。”当下,为了应试的需要,我们在数学教学中更多注重的是技能、技巧的训练,数学课堂上只讲抽象的数学公式和结论,不讲数学知识的实际来源和应用方法。本文从课堂教学、实践活动二个方面阐述了如何实行课堂和课外相结合,提高学生的数学应用能力,实现数学源于生活,数学用于生活的目标。 “Mathematical Curriculum Standards” clearly states: To enable students to “learn from the mathematical point of view to identify problems and raise questions, the comprehensive use of mathematical knowledge to solve simple practical problems, and enhance the sense of application, improve practical ability.” "At present, in order to test Need, we pay more attention to mathematics teaching skills, skills training, math class only abstract mathematical formulas and conclusions, not to mention the actual source of math knowledge and application methods. This article elaborates how to combine classroom and extracurricular activities from two aspects of classroom teaching and practical activities to improve students’ ability to apply maths and achieve the goal of using mathematics from life and using mathematics to life.
