ITEM DEVELOPMENT AND PILOT TESTING OF THE MINI-MAP

开发技术公司提出开发迷你地图，简称 筛查试验，以确定哪些学龄前儿童有患癌症的风险 学习障碍。迷你地图将在研究的基础上发展 米勒学龄前儿童评估(MAP)，一个更全面的， 预测仪器，并作为地图的配套产品。这个 迷你地图是为了直接回应出版商的要求而提出的 和消费者开发一个版本的地图，它将是可靠的，但 长度更短，价格更便宜。全面的项目选择将 符合公认的测试开发心理测量学标准 实际考虑。项目选择将基于：广泛的， 以前的项目研究和预测效度，重测，以及 每个项目的可靠性系数；成本；管理时间；以及 营销方面的考虑。由此产生的项目池将进行试点测试 关于160名科罗拉多州儿童(N=120名正常，N=40名高危儿童)，数据将是 分析(对项目难度和辨别力的估计)。在第二阶段， 迷你地图将以3200名儿童为样本进行全国标准化 按年龄(2至6岁)、种族、性别和社会经济地位分层 根据美国人口普查统计数据。制造和营销将是 由一家大型出版公司承接。残障的盛行 条件结合现有的教育和医疗努力 尽可能小地识别儿童为儿童创造了巨大的市场 建议的学龄前筛查工具。

Developmental Technologies proposes to develop the Mini-MAP, a short screening test to determine which preschool aged children are at risk for learning disabilities. The Mini-MAP will be developed from the research of the Miller Assessment for Preschoolers (MAP), a more comprehensive, predictive instrument and serve as a companion product to the MAP. The Mini-MAP is being proposed in direct response to requests from publishers and consumers to develop a version of the MAP that would be as reliable but shorter in length and less expensive. Comprehensive item selection will occur to meet recognized psychometric standards for test development and practical considerations. Item selection will be based on: extensive, previous item research and predictive validity, test retest, and reliability coefficients for each item; cost; administration time; and marketing considerations. The resulting pool of items will be pilot tested on 160 Colorado children (N=120 normal, N=40 at risk) and data will be analyzed (estimates of item difficulty and discrimination). In Phase II, the Mini-MAP will be nationally standardized on a sample of 3200 children stratified by age (2 to 6 years), race, sex, and socio-economic status according to U. S. Census statistics. Manufacturing and marketing will be undertaken by a major publishing firm. The prevalence of handicapping conditions combined with existing educational and medical efforts to identify children as young as possible creates a large market for the proposed preschool screening instrument.
