PEMBELAJARAN MATEMATIKA MENGGUNAKAN MEDIA GEOGEBRA PADA HASIL BELAJAR SISWA SMPI DARUDDA'WAH KELAS VIII

The research was motivated by the low learning outcomes of students on the topic of congruence and similarity, as well as the limited use of interactive learning media. This research aimed to determine the improvement in students’ learning outcomes through the implemntation og mathematics learning using Geogebra as a supprting tool at SMPI Darudda’wah. This research employed a quantitative approach with a pre-expremental research design using a One Group Pretest- Posttest Design. The sample consisted of all 15 Grade VIII student at SMPI Darudda’wah, selected using a saturated sampling technique. Data were collected through observation and tests in the form of prest and posttest. The learning outcome data were analyzed using descriptive statistics and the N-Gain test. The results showed that the implementation og learning using Geogebra as a supporting tool achieved a percentage of 88.75%, which was categorized as very good. The descriptive statistical analysis showed that the average pretest score of 35.20 increased to 81.33 on the posttest. The minimum score increased from 24 to 72, while the maximum score increased from 48 to 96. The N-Gain analysis resulted in an average score of 0.70, which was categorized as high. Of the 15 students, 8 students achieved a high N-Gain category and 7 students achieved a medium category. Based on these results, it can be concluded that the implementation of mathematics learning using Geogebra as a supporting tool was accompanied by an improvement in students’ learning outcomes on the tropic of congruence and similarity in Grade VIII at SMPI Darudda’wah.
