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.
