Empirical Study of Learning Losses in Frontline Regions of Ukraine (2025)

This dataset contains empirical data collected as part of PhD dissertation research on learning losses in Ukrainian general secondary education during the war. Data were collected in partnership with the Ukrainian Association of Education Researchers (NGO DOCCU), within the "12 Steps to Overcoming Learning Losses" professional development programme. The dataset comprises three components: (1) diagnostic test results of 714 students in grades 4–11 from Kharkiv, Donetsk, and Sumy oblasts across five subjects (English, Mathematics, Natural Sciences, History, Ukrainian Language), collected in November 2025; (2) structured survey responses from 875 teachers across three waves (January, February, and September 2025), covering their perceptions of learning losses, affected topics, prior experience, and professional development needs; (3) qualitative Padlet board data from the same three waves, capturing teachers' open-ended responses to two prompts: "What I know about learning losses" and "My expectations from the programme." All personally identifiable information (full names and email addresses) has been removed from quantitative files. Padlet responses are retained as collected, as they were visible to all programme participants on a public board.本数据集收录了为开展“战争期间乌克兰普通中等教育学习损失”相关博士学位论文研究而采集的实证数据。本数据由乌克兰教育研究者协会（非政府组织DOCCU）合作采集，依托“克服学习损失的12步”专业发展项目开展。 本数据集包含三个组成部分： (1) 2025年11月采集的诊断测试结果，涉及哈尔科夫州、顿涅茨克州和苏梅州4至11年级共714名学生，测试覆盖英语、数学、自然科学、历史与乌克兰语五门学科； (2) 三轮（2025年1月、2月及9月）共875名教师的结构化问卷反馈，内容涵盖教师对学习损失的认知、受影响的教学主题、既往从教经验以及专业发展需求； (3) 同三轮采集的Padlet留言板质性数据，收录教师针对两个开放式提示的回复：“我所了解的学习损失”与“我对本项目的期望”。 所有量化文件均已移除个人可识别信息（全名及电子邮箱地址）。Padlet留言板回复则按原始采集状态保留，因其在公开面板中对所有项目参与者均可见。
