Early Childhood Longitudinal Study: Birth Cohort, 2001-2002, Preschool Data [United States]

The Early Childhood Longitudinal Study (ECLS)is designed to provide decision makers, researchers, child care providers, teachers, and parents with detailed information about children's early life experiences. The birth cohort of the Early Childhood Longitudinal Study (ECLS-B) looks at children's health, development, care, and education during the formative years from birth through first grade. This third wave of the data was collected when the cohort was preschool aged. For the preschool collection, the ECLS-B child assessment protocol was modified to take into account the study children's growing competencies and to focus more on indicators of school readiness. The BSF-R was replaced with an early reading and mathematics assessment similar to the assessments used in the Early Childhood Longitudinal Study, Kindergarten Class of 1998-99 (ECLS-K) kindergarten and first grade collections. Unique to the preschool wave was the assessment of children's knowledge of basic colors. Fine motor skills were assessed by asking children to copy a series of forms/shapes drawn by assessors and to build structures using blocks. Gross motor skills were assessed by asking children to jump, balance on one foot, hop on one foot, skip, walk backward along a line, and catch a bean bag. Additionally, as in the previous waves, children's social interactions with the parent respondent were assessed using the Two Bags Task. All children had their height, weight, and middle-upper arm circumference (MUAC) measured, and children born with very low birth weight had their head circumference measured.

《早期儿童纵向研究》（ECLS）旨在为决策者、研究人员、儿童保育提供者、教师以及家长提供关于儿童早期生活经历的详细信息。早期儿童纵向研究（ECLS-B）的出生队列考察了儿童在从出生至一年级这一形成期内的健康状况、发展、照料和教育。本数据集的第三波收集发生在该队列处于学龄前阶段。在学龄前数据的收集过程中，ECLS-B的儿童评估方案经过调整，以适应研究儿童日益增长的技能，并更专注于学校准备指标的评估。BSF-R被替换为与早期儿童纵向研究（ECLS-K）1998-99届幼儿园及一年级收集所使用的评估相类似的早期阅读和数学评估。在学龄前阶段，独特之处在于对儿童基本颜色知识的评估。精细运动技能通过要求儿童复制评估者绘制的系列形状/图案以及使用积木搭建结构来评估。粗大运动技能则通过要求儿童跳跃、单脚站立、单脚跳、跳绳、沿直线后退行走以及接住豆袋等方式进行评估。此外，与之前的数据收集波次一样，使用两个包裹任务来评估儿童与家长受访者的社会互动。所有儿童均测量了身高、体重和中上臂围（MUAC），而出生体重极低的儿童还测量了头围。}
