情境是联系生活与学生学习之间的重要桥梁,是将固化的课程知识转化为鲜活的生命形态的重要载体。而有效的问题情境则是课堂教学的润滑油、催化剂,它不仅能激发学生的学习兴趣,更重要的是能启迪学生的思维,培养学生的创新意识,从而提高教学的有效性。因此,在数学教学中,教师应精心设计问题情境,帮助学生更好地发现问题、分析问题、解决问题。在此,笔者结合教学实践谈谈以下几点看法,与读者交流。1创设悬疑性问题情境问题的设计要注重策略,我们应竭力点燃学生思维的火花,激发他们的求知欲,并有意识地为他们提
Situation is an important bridge between contact life and student learning. It is an important carrier for transforming the curriculum knowledge into a vivid life form. However, the effective problem situation is the lubricant and catalyst of classroom teaching. It not only can arouse students’ interest in learning, but more importantly it can enlighten students’ thinking and cultivate students’ sense of innovation so as to improve the effectiveness of teaching. Therefore, in mathematics teaching, teachers should carefully design the problem situation, help students to better identify the problem, analyze the problem and solve the problem. Here, I combine the teaching practice to talk about the following views, and readers exchange. 1 create suspense problem Situational problems should be designed to focus on strategies, we should try their best to ignite the spark of thinking, stimulate their thirst for knowledge, and consciously for their mention
