Abstract

The study aims to identify the forms of students’ learning difficulties and the factors underlying them. This research employed a descriptive qualitative method involving seven sixth-grade students at SDN Tegalharjo, Surakarta. Data were collected through semi-structured interviews, classroom observations, and document analysis, and then analyzed using the Miles and Huberman model. The results indicate that most students have a good understanding of basic statistical concepts due to the contextual learning approach applied by the teacher; however, the main difficulties arise at the calculation stage, particularly in calculating the mean with decimal results and determining the median due to a lack of accuracy in ordering data. The factors contributing to these difficulties include limited arithmetic skills, low accuracy, and varying levels of learning support from families. Students’ learning motivation is relatively high, especially when the material is linked to real-life experiences and practical activities. These findings emphasize the need to strengthen basic numeracy skills, improve accuracy, and involve the learning environment to enhance elementary school students’ understanding of Statistics. Based on these findings, it can be concluded that improving elementary students’ understanding of Statistics should focus on reinforcing basic numeracy skills, accuracy in calculation processes, and synergy between contextual learning strategies and learning environment support.   Keyword: Mathematics, Elementary School, Statistics.

Abstract

This study aims to analyze the application of the Problem-Based Learning (PBL) model in developing elementary school students' statistical literacy skills. This study used a descriptive qualitative approach involving 16 sixth-grade students from Sanggrahan Public Elementary School in Surakarta City. Data were obtained through observation, interviews, and document analysis, then analyzed using the Miles & Huberman model. The results showed that the application of PBL was able to improve students' data interpretation skills, critical thinking, and active involvement in statistics learning. Students admitted that it was easier to understand the material because the learning activities involved real experiences and group discussions, while teachers and the principal stated that PBL had a positive impact on the quality of learning even though it required more preparation and time. Factors supporting success included teachers' mastery of PBL, adequate facilities and infrastructure, and school support; while obstacles included time constraints and the need for intensive preparation. This study confirms that PBL is an effective approach to improve elementary school students' statistical literacy and is relevant for application in contextual mathematics learning.   Keyword: Problem-Based Learning, Statistical Literacy, Elementary School.

Abstract

This study aims to systematically optimize the hyperparameters of an Artificial Neural Network (ANN) using an algorithm-based approach to obtain the best configuration, as well as to compare the air temperature prediction accuracy of ANN with other machine learning algorithms. Feature selection was performed using a physical approach to identify variables that significantly influence air temperature, while ANN hyperparameter optimization was conducted using the Random Search method. The ANN model was compared with Linear Regression (LR), Random Forest (RF), and Support Vector Regression (SVR) in predicting air temperature. Model performance was evaluated using Mean Squared Error (MSE), Root Mean Squared Error (RMSE), Mean Absolute Error (MAE), Mean Absolute Percentage Error (MAPE), and the coefficient of determination (R²). The results indicate that the ANN model generally achieved lower MSE, RMSE, MAE, and MAPE values and higher R² values compared to the other methods across four study locations: Banyuwangi, Juanda, Sangkapura, and Pasuruan. These findings demonstrate that ANN with properly optimized hyperparameters can provide more accurate air temperature predictions..   Keywords: Artificial Neural Network, East Java, Machine Learning, Air Temperature
