【案例主题】学生积极参与,从不同角度分析问题,体现了活动、自由、创新等现代教学理念。【背景】新课标要求,应使学生经历从实际问题中建立数学模型,并估计、求解和验证解的正确性与合理性。本节内容是在学生掌握了一元一次方程应用和解一元一次不等式的基础上的新内容。在课堂上让学生学会从具体问题情景中抽象出数学问题,建立数学关系式,获得合理的解答。【事例】我在进行七年级数学下册《一元一次不等式的应用》
Case Theme Students actively participate in the analysis of problems from different perspectives and embody the modern teaching concepts of activity, freedom and innovation. 【Background】 The requirements of the new curriculum should enable students to experience the establishment of mathematical models from practical problems, and estimate, solve and verify the correctness and rationality of the solution. The content of this section is based on the student’s mastery of a unitary equation to solve the unary inequality. In class, students learn to abstract math problems from specific problem scenarios, establish mathematical relationships, and get reasonable answers.
