数学活动经验是数学教学的重要目标。这一目标早已为广大教师所重视,但是在实践活动中一个普遍的现象就是效率太低,本文笔者结合“长方体和正方体的认识”这一案例阐述了相关策略,以期能帮助学生提升在活动中积累经验的效率。《义务教育数学课程标准(2011年版)》特别指出:“数学活动经验的积累是提高学生数学素养的重要标志,帮助学生积累数学活动经验是数学教学的重要目标。”但是在实践
Mathematical activities experience is an important goal of mathematics teaching. This goal has long been valued by the majority of teachers, but a common phenomenon in practice is that the efficiency is too low. In this paper, the author combines the case of “the understanding of cuboids and cuboids” to elaborate the relevant strategies in order to help students improve The accumulation of experience in the activity of efficiency. “Compulsory Education Mathematics Curriculum Standard (2011 Edition),” In particular: “The accumulation of mathematical activity experience is an important symbol of improving students’ mathematical literacy, to help students accumulate experience in math activities is an important goal of mathematics teaching.” However, in practice
