The use of technology in the pedagogical process is growing at a phenomenal rate and has revolutionized the way students learn. As a result, there is a need for integrating technology into students’ mathematical activities. GeoGebra is a technology software that supports teaching and learning mathematics, especially geometry, algebra, and statistics. This study investigated the students’ knowledge of the integration of GeoGebra in learning mathematics in lower secondary schools in Wakiso District, Uganda. The study utilized quasi-experimental and cross-sectional designs with 42 senior two students in the experimental and 43 in the control group. Data were collected using pre-tests, post-tests, and questionnaires to identify the students’ difficult geometric concepts when learning mathematics, establish the impact of GeoGebra-based training on the students’ learning, and examine the relationship between students’ perceived ease of use of GeoGebra and its integration in learning mathematics. Independent samples t-test, Pearson's linear correlation, and descriptive statistics such as mean, standard deviation, percentages, and frequencies were employed to analyze the data. The study revealed that reflection on the Cartesian plane was the most abstract geometric concept to learn. The results further revealed a statistically significant mean difference between pre-test and post-test scores in favour of the experimental group after the intervention. Furthermore, a moderately significant positive linear correlation existed between students’ perceived ease of use of GeoGebra and its integration in learning reflection on the Cartesian plane. Therefore, the study recommends urgently training students to incorporate this interactive educational software into their mathematics learning.<p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/soc/0871/a.php" alt="Hit counter" /></p>
