关于选考科目等级赋分的改进:历史经验、现实限制与可能方向

The Improvement of Percentile Band Score: Experience,Restriction and Possible Direction

由高考科目调整引发的不同科目成绩之间的可比性问题,已多次成为高考改革面临的一个难题。有关省份的改革经验表明,标准分在分数转换上有着明显弊端,并不是解决这一难题的理想方案。在原始分主导、总分录取等诸多前置条件的约束下,现行等级分也是一种简化的"标准分"。等级分在解决分数的可比性、总分的可加性上做出了有益探索,但也带来了一些不符合教学导向的消极影响。在不打破当前高考分数使用方式的前提下,等级分在考试技术层面仍具有改进的空间。

The score comparability of different subjects in Gaokao reform has always been a big concern in recent years.Experience in some provinces shows that standard score reform is not a proper solution to this problem because of its technical flaws in the process of score conversion.Percentile band score,despite some restrictions like using total raw score in admission,seems a compromised choice.To some extent,percentile band score,as a kind of simplified standard score,makes it possible to compare the scores of different subjects before adding them together while leaving some negative influence on teaching and learning.However,technically,percentile band score still needs improving given the existing practice of using Gaokao scores.
