Numeracy is an important skill that elementary school students must have, but in reality it is still relatively low because learning tends to be conventional and less contextual. Numeracy does not only include the ability to count, but also the ability to understand, use, and interpret numbers and data in various daily life contexts. One of the causes of low student numeracy is a learning approach that is less interesting and not related to real situations. This study aims to test the effectiveness of the contextual learning model (Contextual Teaching and Learning/CTL) in improving students' mathematical numeracy skills. The research design used was a one-group pretest-posttest experiment with 23 fifth-grade students of SDN 002 Teluk Bintan as subjects. The instrument in the form of a numeracy test was given before and after the implementation of CTL, then the data were analyzed using prerequisite tests (normality and homogeneity) followed by a paired sample t-test. The results showed a significant increase in students' numeracy skills. The average pretest score of 24.78 increased to 73.91 in the posttest with a significance value of 0.000 <0.05. This increase proves that CTL is effective in helping students master numeracy through a learning process that links mathematical concepts with real experiences. Thus, the contextual learning model can be an alternative learning strategy that is relevant for increasing elementary school students' numeracy, while emphasizing the importance of implementing a more applicable approach in mathematics learning.

Elementary education is the fundamental stage in shaping students’ character, attitudes, and learning motivation. Learning interest plays a vital role in determining students’ success in understanding and mastering the lessons. However, differences in background, abilities, and learning styles often cause significant variations in students’ interest. Therefore, it is necessary to apply an analytical method that can group students based on their level of learning interest so that teachers can provide appropriate learning strategies. This study aims to implement the K-Means Clustering algorithm to identify the learning interest of students at Sekolah Dasar Negeri Puu Naga. The research method used is a quantitative approach with data collected through questionnaires consisting of several indicators of learning interest, such as perseverance in completing assignments, enthusiasm during lessons, attention to teacher explanations, and participation in class activities. The collected data were then analyzed using the K-Means algorithm to form several clusters of learning interest. The data processing stages included determining the number of clusters, selecting the initial centroid, calculating the distance of data to the centroid, grouping data, and iterating until a stable clustering result was achieved. The results of the study show that the K-Means algorithm successfully grouped students into three main categories, namely high, medium, and low learning interest. Students in the high-interest group consistently demonstrated active learning behavior and strong intrinsic motivation, while those in the medium group showed fluctuating interest influenced by external factors such as the learning environment and teaching methods. Meanwhile, students in the low-interest group displayed a lack of attention and motivation, thus requiring special interventions. These findings provide valuable insights for the school, especially teachers, in designing adaptive and personalized teaching strategies. In conclusion, the application of the K-Means algorithm is proven effective as an analytical tool to identify students’ learning interest.

This study was motivated by the low performance of students’ drop shot skills in elementary school badminton extracurricular activities, where the success rate of shots remained low despite regular training. The aim of this research was to analyze the effect of drop shot training using two methods—fixed targets and variable targets—on improving students’ shot accuracy. The study employed an experimental method with a pretest-posttest control group design. The sample consisted of 30 students selected through purposive sampling, with the requirement of having participated in badminton extracurricular activities for at least one year. The participants were divided into two groups: 15 students underwent fixed-target training, and 15 students underwent variable-target training. The training program was implemented over six weeks with a frequency of three sessions per week. The results indicated that both training methods significantly improved students’ drop shot accuracy. However, the variable-target training group showed greater improvement compared to the fixed-target group. This was due to the training variation, which required better concentration, adaptability, and decision-making, making it more similar to real game conditions. These findings highlight the importance of applying varied training methods in developing students’ basic badminton skills. Therefore, this study provides practical implications for coaches to prioritize variable-target training methods in coaching programs to enhance the effectiveness of technical skills, particularly the drop shot.
