补充资料：可控性与非可控性投入
可控性与非可控性投入
可控性与非可控性投人可控性投入指学校和教育行政部门可以控制的教育资源投入。学校可以对教学负担、班级规模、课程教学单元的数量、每个教师承担的学科教学任务的平均量等可控性投入进行调节和平衡，以改进教学质量。教育行政部门可以对教师的专业准备程度、教学经验、培训要求、教师工资、设备供应、生活费用、图书馆藏书等投入进行选择，以调节教育的供给与需求。而非可控性投入指学校和教育行政部门不能控制的教育资源投入。如学生的种族、性别、年龄及家长的社会经济背景等无法控制的因素对教育有着不同程度的影响。教育部门不能控制学生家长的教育水平和收入状况，但应当推动教育机会平等的社会经济环境的实现。
