新课程下,如何创设高质量的问题情境,并以此引导学生主动地学习数学、深入地思考数学、有效地提升数学修养,已成为数学教师不容回避的问题。上半年,笔者受邀听了一节“一元一次不等式组(第1课时)”公开课,对其问题情境的设计、使用颇有感触,本文就此谈些思考。片段一:新课导入。师:前面我们学过一元一次不等式,请一位同学来说说解一元一次不等式的步骤。 Under the new curriculum, how to create a high-quality problem situation and guide students to take the initiative to learn mathematics, think deeply about mathematics and improve mathematics accomplishment effectively has become an unavoidable problem for math teachers. In the first half of the year, the author was invited to listen to a section titled “Unary Inequalities (Lesson 1)” and “Open Lessons”. Fragment one: a new lesson into. Teacher: In front of us once learned inequality, ask a classmate to explain the steps of inequality once a dollar.
