Pre-Post-Test GOCUT Data: Senior 4 Rwandan physics students

Geometric Optics Conceptual Understanding Test (GOCUT). We collected items from existing inventories to form this test, GOCUT. It was used to test the effect of PhET simulations and YouTube videos as instructional tools on students' active learning of optics. The data may be reused in various ways. The MS Excel file contains the raw data and little analysis. The test itself is also uploaded for anyone to use. The following publications are linked to this dataset: https://doi.org/10.1080/18117295.2020.1818042 https://doi.org/10.1007/s10956-021-09913-4几何光学概念理解测试（Geometric Optics Conceptual Understanding Test，GOCUT）。本测试从现有题库中选取试题编制而成，用于评估PhET仿真（PhET simulations）与YouTube视频作为教学工具对学生主动学习光学知识的教学效果。本数据集支持多种途径的重复使用，配套的MS Excel文件包含原始数据与少量分析内容。测试题本也已上传，可供所有使用者使用。本数据集关联的已发表文献如下：https://doi.org/10.1080/18117295.2020.1818042 https://doi.org/10.1007/s10956-021-09913-4
