新课程标准指出有效的数学学习活动不能单纯地领会模仿与记忆,动手操作也是学生学习数学的一种重要方式.课程标准下的新教材非常重视学生操作能力的培养,提倡学生在“做数学”中学数学,注意发挥学生主体在认识活动中的主动和能动作用.近年来的中考也频频出现了“动手操作型”试题,让学生在动手操作的基础上探索相关的图形和数量,以考查学生的创新精神和实践能力.现略举几例加以浅析:
The new curriculum standard points out that effective mathematics learning activities cannot simply understand imitation and memory, and hands-on operation is also an important way for students to learn mathematics. New textbooks under the curriculum standards attach great importance to the cultivation of students’ operational ability, and encourage students to “do mathematics”. In middle school mathematics, attention is paid to the active and active use of student bodies in cognitive activities. In recent years, there have been “hands-on operation” test questions in the middle school entrance examination, allowing students to explore relevant figures and numbers on the basis of hands-on operations to examine students. The spirit of innovation and practical ability. Here are a few examples to explain:
