Three subtests and the two-thirds items ofWPPSI were replaced. C-WYCSI consists of two sets of norms, one is madeup of urban children (N=2200) and another is made up of rural children(N=1120). The following psychometrical characteristics of the scale are considered: most floors of th...             本文介绍了中国-韦氏幼儿智力量表(C-WYCSI)的编制情况。C-WYCSI是以WPPSI为蓝本编制,包括城市常模(N=2200人)和农村常模(N=1120人)。作者从心理测量学角度对常模的构成、测验项目的筛选及上下限、信度和效度等问题进行了分析与讨论。结果提示:尽管C-WYCSI改变很大,但项目的难度和区分度是较满意的;城市常模的测验下限明显改善,但上限不及原量表;各种信度均达到测量学认可的水平;效度研究结果表明:C-WYCSI较好地保持了WPPSI的功能。 文摘来源          This thesis expounds the construct-ing of the Chinese Reading AchievementScale for third year students in juniormiddle school.We format the scale andadministered it to the general middleschool standard samples in GuangZhou.The results show that its diffi-culty is appropriate,its discriminationis rather good,and its reliability andvalidity are relatively high.It is suit-able for measuring the level of Chi-nese reading for third year students injunior middle school.             本研究介绍了初中三年级《语文阅读水平量表》的编制情况。我们编制了这个量表,用它对广州市完全中学标准化样本进行测试,结果表明,该量表难度恰当,区分度较好,信度效度较高,适合完全中学初三级作为测量语文阅读水平的量具. 文摘来源   << 更多相关文摘         相关查询: 条目区分度 区分度系数 项目区分度 区分度指数 区分度分析 试题区分度 双可区分度 区( 分度 难度和区分度 区 词的位置区分度  对查询结果不满意
