Abstract

The purpose of this study was to determine the increase in student learning outcomes using the Kahoot application in class XI IPS 1 SMA Negeri 3 Palembang. The research method used was classroom action research (CAR) with a sample size of 35. The data collection method used tests to obtain learning outcomes in the pre-cycle with an average grade of 65.4, then cycle I with an average grade of 73.5 , and cycle II with an average value of 85.6 which experienced an increase. It can be concluded that the application of the Kahoot application can improve the learning outcomes of students in class XI IPS 1 SMA Negeri 3 Palembang.

Abstract

The purpose of this research is to examine the relation between mathematical problem-solving ability and mathematical communication ability by applying k-means clustering in grouping students. This research uses a quantitative approach with a correlational research method. The population of this research is the eighth-grade students of SMP Negeri 3 Purwakarta, with a total of 355 students. The sampling technique uses simple random sampling and is calculated using the Slovin formula, so the total sample is 79 students. The instrument used in this research is a subjective test in the form of questions of mathematical problem-solving ability and mathematical communication ability. The data analysis technique in this research is k-means clustering to group the data and correlation hypothesis test. The results show that  37 students fall into Cluster 1 (high-ability), 28 students into Cluster 2 (medium-ability), and 14 students into Cluster 3 (low-ability). In all samples and cluster 1, it is stated that at the 95% confidence level there is a significant relationship between mathematical problem-solving ability and mathematical communication ability. However, in all samples, it shows a weak relationship and the contribution of mathematical problem-solving ability to mathematical communication ability is 9.22%, and vice versa. While in Cluster 1, it shows a medium relationship and the contribution of mathematical problem-solving ability to mathematical communication ability is 31.2%, and vice versa. In Cluster 2 and Cluster 3, the analysis indicates that although there is a relationship at the 95% confidence level, it is not statistically significant.
