摘要
“空间观念”是图形与几何教学的首要目标．利用自编的“空间观念”测试卷对随机抽取的182名九年级学生进行测试，对测试结果进行分析得到如下结论：大多数九年级学生空间观念水平己达到了《标准》的要求；学生在投影、图形的运动变换方面的表现要优于在视图与展开、方位方面的表现；学业水平较高的学校与学业水平一般的学校的学生空间观念水平存在显著差异；九年级学生空间观念水平与其数学成绩之间存在显著正相关；九年级学生空间观念水平不存在显著的性别差异．
＂Space sense＂ is the primary goal of graphics and geometry teaching. In this paper, we use the self-compiled test paper to test 182 nine-grade students who were selected by random. We draw out the following conclusion by analyzing the test results： The level of space sense of most students has reached the requirements stated in the national curriculum standard. Students showed better performance in the projection and graphic motion change than that in the position and view and unfold. Students in better school have better development in the space sense, and has litter difference in the understanding of projection and graphic motion change, but still large difference in the view and unfold, position. Test of students in junior three shows that students has better space sense if they do well in their mathematic course. The gender difference is not obvious in the development of space sense.
