The Classroom Learning Activities Checklist (CLAC) is a brief classroom observation measure that assesses task-oriented and self-regulated learning in early childhood environments. We assessed the tool’s dimensionality and validity in predicting prekindergarten (PreK) learning gains. The study sample is from the Midwest Child-Parent Center (MCPC) program, an evidence-based PreK–3rd grade school reform model providing comprehensive educational and family support services. Data from 1358 enrolled students in 72 observed classrooms indicated that a 2-factor model—instructional responsiveness and student engagement—explained 50% of the variance in item scores. Evidence for construct validity was strong. Linear and probit regression analyses indicated that CLAC scores independently predicted learning gains in literacy (ES = .34 SD) and math (ES = .30 SD) on the Teaching Strategies Gold Assessment System, a standardized performance assessment. Findings support the validity of the CLAC in assessing the classroom learning environment. Implications for program monitoring, evaluation, and professional development are discussed.

学前班课堂学习活动清单的维度和预测有效性


课堂学习活动检查表 (CLAC) 是一项简短的课堂观察措施，用于评估幼儿环境中任务导向和自我调节的学习。我们评估了该工具在预测学前班 (PreK) 学习成果方面的维度和有效性。研究样本来自中西部儿童家长中心 (MCPC) 计划，这是一个基于证据的学前班至三年级学校改革模式，提供全面的教育和家庭支持服务。来自 72 个观察教室的 1358 名注册学生的数据表明，二因素模型（教学响应性和学生参与度）解释了 50% 的项目分数差异。结构有效性的证据是强有力的。线性和概率回归分析表明，CLAC 分数独立预测了教学策略黄金评估系统（一种标准化绩效评估）中读写能力 (ES = 0.34 SD) 和数学 (ES = 0.30 SD) 的学习收益。研究结果支持 CLAC 在评估课堂学习环境方面的有效性。讨论了对项目监控、评估和专业发展的影响。
