Research Team: Korea, Learner's Perspective Study

This collection consists of data collected in Korea (2004) as part of the Learner's Perspective Study, a sixteen-country international project to document "well-taught" mathematics classrooms. Data was collected through the use of three cameras (on the teacher, class as a whole and a student group), supplemented by post-lesson video-stimulated interviews (audio and video records) with students and teachers, test data, teacher questionnaires, and copies of student and teacher written material.

Data was collected from three schools and from a sequence of at least ten year 8 mathematics lessons in each school, which were generally focussed on the same topic e.g. algebra.

This collection includes: video files (format: H.264); lesson materials (jpg, pdf), including a seating plan for the classroom with names of students (de-identified); lesson form table, a detailed deconstruction of the lesson; teacher questionnaire; time-coded transcriptions and translations (where relevant); student's work from the lesson (scanned pdf file); researcher field notes; consent forms; syllabus; school timetables; research team bi-annual meeting minutes.

The collection is housed on RAID5 fibre channel array connected to the videoportal server. The ICCR also maintains hard copies (DVD/CD/Pocket Hard Disk) of all data as it was originally delivered.

Collection size: 26GB

作为一项覆盖16个国家、旨在记录教学精良的数学课堂实况的国际合作计划——“学习者视角研究（Learner's Perspective Study）”的一部分，本数据集为2004年在韩国采集所得。数据采集通过三台摄像机分别拍摄教师、全班课堂场景及学生小组活动完成，并辅以面向师生的课后视频激发式访谈（含音视频记录）、测试数据、教师问卷以及师生手写材料副本。

数据采集自3所学校，每所学校均采集至少10节连贯的八年级数学课程，且课程主题基本统一，例如代数模块。

本数据集包含以下内容：视频文件（格式：H.264）；课堂教学材料（格式：JPG、PDF），其中包含已完成去标识化处理的带学生姓名的教室座位平面图；课程解构记录表（用于对单节课程开展详细拆解分析的表格）；教师问卷；带时间编码的转录文本及相关翻译（如适用）；学生课堂作业（扫描版PDF文件）；研究人员实地笔记；知情同意书；教学大纲；学校课程表；研究团队半年度会议纪要。

该数据集存储于连接至视频门户服务器的RAID5光纤通道阵列中。ICCR同时留存所有原始交付数据的纸质副本，存储介质涵盖DVD、CD及便携式硬盘。

数据集总容量为26GB。
