NCTE Transcripts
收藏资源简介:
NCTE Transcripts是由斯坦福大学开发的,包含1660条4至5年级小学数学课堂的转录数据集。该数据集收集于2010至2013年,涵盖了317名教师在四个主要服务历史边缘化学生的学区。数据集不仅包含匿名化的转录文本,还附带丰富的元数据,如对话性话语移动的逐轮注释、课堂观察分数、人口统计信息、调查回复和学生测试成绩。此数据集旨在通过自然语言处理模型识别对话性话语移动,并探索这些移动与课堂观察分数及学习成果之间的关联,从而为研究人员、教育者和政策制定者提供了解和改进K-12教学的可能性。
NCTE Transcripts is a dataset developed by Stanford University, consisting of 1,660 transcripts of elementary mathematics classrooms for grades 4 and 5. Collected between 2010 and 2013, the dataset covers 317 teachers across four major school districts that historically serve marginalized student populations. In addition to anonymized transcript texts, the dataset also provides rich metadata, including turn-by-turn annotations for conversational discourse moves, classroom observation scores, demographic information, survey responses, and student test scores. The core objectives of this dataset are to identify conversational discourse moves via natural language processing models, and to investigate the correlations between these moves, classroom observation scores and student learning outcomes, thereby offering researchers, educators and policymakers opportunities to understand and improve K-12 instructional practices.
