摘　　要：培养和发展中小学生的几何直观能力,是我国数学新课改的重要目标之一。对我国东、中、西部三个地区83,792名八年级学生进行几何直观能力学业质量监测,结果显示:我国八年级学生的几何直观能力总体水平一般;不同地域、不同学业水平学生之间的几何直观表现存在明显差异,不同性别学生之间的几何直观表现基本没差异;相较于几何问题和统计问题解决能力,学生利用图形解决代数问题的能力相对较弱。为了提高学生的几何直观能力,教师应该运用图形直观指导学生认识新知识和解决问题,发挥现代教育技术可视化的支持作用,同时在数与代数领域着重提高学生的几何直观水平。It is one of the important goals to cultivate and develop the geometry intuition of students in primary and secondary schools. By monitoring the academic quality of geometric intuition among 83,792 students in grade eight among three regions of eastern,central and western China,results show that the overall performance of students' geometric intuition in grade eight is general;there are obvious differences in geometric intuitions between students from different regions and academic levels,and no difference in those between different gender students;compared to solving abilities about geometric problems and statistical ones,students are relatively weak in solving algebraic problems using graphics. In order to improve students' geometric intuitions,teachers should direct students to understand new knowledge and solve problems by using graphics,take on the role of technology visualization of number education,and focus on improving the students' geometric intuition level in the field of number and algebra.
