一、引言为了促进学生有意义学习,培养其问题解决能力,《小学数学课程标准》强调利用现代信息技术为学生创设利于开展探索性数学活动的学习环境。在该《标准》指引下,一线教师致力于在教学中利用现代信息技术创建具体的问题情境来引导学生积极观察、实验、测量、验证和推理一些简单的数学实际问题。一个公认的事实,数学课程是被分为数、代数、几何、统计与概率等几个独立领域教授给学生的,这样一来学生通过课堂教学也只能学 I. INTRODUCTION In order to promote students’ meaningful learning and develop their problem-solving abilities, the Primary Mathematics Curriculum Standard emphasizes the use of modern information technology to create a learning environment conducive to exploratory mathematical activities for students. Under the guidance of the “standard”, front-line teachers are committed to using the modern information technology in teaching to create specific problem situations to guide students to actively observe, experiment, measure, verify and reason about some simple mathematical practical problems. An accepted fact is that math courses are taught to students in several separate areas such as numbers, algebra, geometry, statistics and probability, so that students can only learn through classroom teaching
