Relationships of mathematics achievement with self-determined motivation and mathematics anxiety among senior two students in Northern Rwanda.

The most important factors affecting students' mathematics achievement are affective-motivational factors. Grounded on self-determination theory, expectancy-value theory, and control-value theory, we examined the relationship between self-determined motivation (i.e.

Dataset for measuring the conceptual understanding of optics in Rwanda.

This dataset is an accumulation of data collected to test Rwandan physics students' conceptual understanding of light phenomena and to assess instructional tools for active learning of optics. We collected and analysed data from 251 grade 11 (senior 5) students using our Light Phenomena Conceptual Assessment (LPCA) tool and from 136 grade 10 (senior 4) students using Geometric Optics Conceptual Understanding Test (GOCUT) in 2019. Before collecting data, we designed and validated LPCA and GOCUT, and tested their reliability.

Classroom observation data collected to document the implementation of physics competence-based curriculum in Rwanda.

Classroom observation has played a role in documenting classroom practices to improve teaching and learning outcomes. This dataset allows teachers, researchers, and educational policymakers to reanalyze it depending on the interest variables and understand Rwanda's current physics education. The data was collected among qualified teachers from selected schools in Kigali city and rural eastern province in Rwanda.
