A. 诊断性评价B. 配置性评价C. 常模参照评价D. 标准参照评价正确答案:BB[解析]本题考查教学测量与评价的分类。
从教学评价的功能看,有配置性评价与诊断性评价之分。
选项B配置性评价,或称准备性评价,一般在教学开始前进行,摸清学生的现有水平及个别差异,以便安排教学。
通过配置性评价,教师可以了解学生对新学习任务的准备状况,确定学生当前的基本能力和起点行为。
选项A诊断性评价有时与配置性评价意义相当,指了解学生的学习基础与个体差异;有时指对经常表现学习困难的学生所做的评价,多半是在形成性评价之后实施。
选项C常模参照评价是指评价时以学生所在团体的平均成绩为参照标准(即所谓常模),根据其在团体中的相对位置(或名次)来报告评价结果。
选项D标准参照评价,是基于某种特定的标准,来评价学生对与教学密切关联的具体知识和技能的掌握程度。
所以,本题的正确答案为B。
