Abstract

This study aims to describe the use of AR: GeoGebra 3D Calculator in improving students' understanding of mathematical concepts in three-dimensional materials. This study uses a quantitative approach with a pseudo-experimental method. The sample consisted of 69 eleventh grade students from MAS Al-Washliyah 22, which was divided into an experimental group (35 students) using AR: GeoGebra 3D Calculator and a control group (34 students) using conventional methods. The data collection technique is carried out through a concept comprehension test, namely pretest and posttest. Data analysis was carried out quantitatively on the test results obtained using an independent t-test test for normalized gain. The results showed that the experimental group showed a significantly higher increase in average scores from pretest to postes compared to the control group. The results of the independent t-test of the postes scores showed that there was a significant difference between the two groups. The normalized gain analysis further confirmed that the experimental group achieved a higher improvement (0.61) than the control group (0.41), with a significant difference (t = 4.876, p <0.001). The results of this study show that the use of AR: GeoGebra 3D Calculator significantly improves students' understanding of concepts in three-dimensional materials compared to conventional methods

Abstract

This research aims to describe gamification-based learning using Kahoot to enhance students' interest in online learning. This study employs a quantitative approach with a quasi-experimental method. The design used is one group pretest-posttest. The sample in this study consists of 30 students from the Physical Education, Health, and Recreation study program. Data collection techniques were conducted through a learning interest questionnaire given before the learning (pretest) and after the learning (posttest) and an observation sheet for the implementation of learning. Data analysis used paired t-test. The research results indicate that there is a 15.5% increase in student learning interest with a t-value of 15.847, p < 0.001, which means there is a significant difference in the increase of student learning interest before and after the implementation of gamification-based learning with Kahoot. The success rate of the learning implementation is 88.75% across all observed aspects, including lesson preparation, execution, student activities, and time management. These findings indicate that gamification-based learning using Kahoot can enhance student learning interest in online learning.

Abstract

This research aims to improve the computational thinking (CT) skills of elementary school students through unplugged coding activity sheets in mathematics learning. The research uses a quantitative approach with a One Group Pretest-Posttest Design pre-experimental design. The subjects of the study are 25 fourth-grade students from Muhammadiyah 18 Medan, selected through purposive sampling. Data was collected using a CT ability test administered before and after the learning session. Data analysis was conducted using a paired sample t-test and N-Gain calculation. The research results show a significant increase in students' CT ability with an average score rising from 54.48 (pre-test) to 73.32 (post-test), a t-statistic value of -86.782, and a significance level of 0.000 (p < 0.05). The N-Gain value of 0.65 indicates the effectiveness of learning in the medium category. All CT indicators showed improvement, with generalization experiencing the highest increase (39.6%), followed by decomposition (39.3%), abstraction (38.9%), and algorithmic thinking (38.6%). However, the debugging and iteration indicators showed relatively lower increases of 28.7% and 23.6%, respectively. This research demonstrates that mathematics learning with unplugged coding activity sheets can be a solution to develop the CT abilities of primary school students with limited technological devices.
