提高数学课堂教学的有效性是每个教师不断追求的目标,而设计有效问题成为教学关键环节。数学有效问题设计的具体措施有:问题设计要抓住数学的本质,让学生在思考中体会数学概念的内涵;问题设计要符合学生的知识水平和认知规律,使学生在最近发展区构建知识体系;问题设计要给予学生思考的空间,让学生思维能够在思考中发展。
Improving the effectiveness of classroom teaching in mathematics is the constant goal pursued by each teacher, and designing effective problems becomes the key link in teaching. Specific measures to design effective mathematical problems are as follows: Problem design should grasp the essence of mathematics so that students can understand the connotation of mathematical concepts in their thinking. The problem design should meet the students’ knowledge level and cognitive rules so that students can build knowledge in the nearest development area System; problem design to give students the space to think, so that students can think in thinking development.
