Abstract

This study aims to determine the effect of the cooperative learning model, specifically the Teams Games Tournaments (TGT) type assisted by Quizizz, on the mathematical literacy skills of 11th-grade students at MAN 1 Mataram in the academic year 2024/2025. This research is a quasi-experimental study using a posttest-only control group design. The population consisted of three 11th-grade science classes with a total of 118 students, and the sample included two classes: XI IPA 1 as the control group, which received direct instruction, and XI IPA 2 as the experimental group, which received the TGT model assisted by Quizizz. The sampling technique used was cluster random sampling. Data were collected through a mathematical literacy skills test administered after the intervention and were analyzed using normality and homogeneity tests. Based on the results, a non-parametric test chi-square test was employed along with the calculation of the effect size. The findings showed a difference in the average scores between the control group (49) and the experimental group (78), indicating the influence of the TGT model assisted by Quizizz on students' mathematical literacy. The effect size value of d = 0.465 falls within the medium category, suggesting a moderate impact. Therefore, the TGT cooperative learning model assisted by Quizizz contributes positively to enhancing students' mathematical literacy, particularly in function-related topics such as trigonometry, logarithms, and algebra. Future studies are recommended to further explore the implementation of this model across different educational levels, subject matter, and broader learning contexts.

Abstract

This study aims to determine the effectiveness of the project-based learning model on student learning outcomes in circle material in grade VIII of SMP Negeri 1 Taliwang for the 2024/2025 school year. This type of research is a quasi experimental design with the nonequivalent posttest only control group design. The population in this study is all grade VIII students at SMP Negeri 1 Taliwang and the sample used is class VIII.4 as an experimental class and VIII.6 as a control class with the number of students in each class of 32 students selected using the cluster random sampling technique. The experimental class was treated with the application of a project-based learning model and the control class applied a conventional learning model. The research data collection technique uses test and observation techniques. The test instrument is in the form of a student learning outcome test (posttest) on circle material and observation sheets. The data analysis technique used the t-test. The results showed that there was a difference in the average learning outcomes of students who applied the project-based learning model, which was 91.2 and students who applied the conventional learning model, which was 68.2 The results showed that there was a significant difference between the learning outcomes of students in the experimental class and the control class. The average score of the students in the experimental class was higher than in the control class. Thus, project-based learning has been proven to be effective in improving students' mathematics learning outcomes on circular materials.

Abstract

The ability to think creatively is one of the important skills that needs to be developed in learning mathematics. This research aims to see that the Open-Ended Problem Based Learning (Open-Ended PBL) model can help improve students' creative mathematical thinking abilities. Using a quasi-experimental approach, research was conducted on class VII students at one of the state junior high schools in Central Buton Regency. Two classes were chosen randomly, namely one as an experimental group, namely class VII-B, which received learning using the Open-Ended PBL model, and the other as a control group, namely class VII-A, with conventional learning. After the learning process, students' creative thinking abilities are analyzed using statistical tests, starting with normality and homogeneity tests as well as the independent sample t-test. The results show that students taught with the Open-Ended PBL model experienced significant improvement, with an average N-gain of 0.42 and a significance value of 0.00. A p-value of less than 0.05 is evidence that the application of the Open-Ended PBL model has a significant influence on increasing students' creative mathematical thinking abilities. These findings show that the Open-Ended PBL approach not only helps students understand mathematics more deeply, but also encourages them to think more openly and creatively. This model can be a strategic choice for teachers in creating more meaningful mathematics learning.

Abstract

Indonesia's tourism sector experienced a drastic decline due to the pandemic, with the number of foreign tourists falling by 64.64% in 2020, disrupting contributions to the country's GDP and foreign exchange. The lack of application of stochastic models to predict foreign tourist arrivals nationwide is a challenge in policy planning. This research aims to build a Markov Chain-based prediction model to estimate the number of foreign tourists in 2026, overcoming the weaknesses of conventional approaches that are deterministic. The method used is the analysis of the probability of transition between states (Increase/Decrease/Stable) based on historical data of tourist arrivals. The prediction results show that the number of foreign tourists in 2026 reached 18,202,215 people, indicating an optimistic growth trend and potential recovery of the tourism sector. The conclusion of this study confirms that the Markov Chain model is effective for macro projection of tourist fluctuations, so that it can be a reference in the preparation of adaptive and data-based tourism policies.

Abstract

Perhitungan integral merupakan salah satu konsep penting dalam matematika yang sering digunakan untuk menentukan luas area di bawah kurva. Namun, tidak semua fungsi dapat diintegralkan secara analitik karena kompleksitas bentuknya. Oleh karena itu, metode numerik seperti metode Simpson 3/8 dan metode Boole diperlukan sebagai pendekatan untuk memperoleh nilai hampiran dari integral tentu. Kedua metode ini memiliki kelebihan masing-masing dalam hal akurasi dan efisiensi. Penelitian ini bertujuan untuk menganalisis efektivitas metode integral numerik Simpson 3/8 dan metode Boole dalam menentukan luas area di bawah kurva melalui implementasi dalam bahasa pemrograman PHP. Penelitian ini menggunakan pendekatan eksperimen murni dengan mengimplementasikan algoritma kedua metode ke dalam aplikasi berbasis web. Pengujian dilakukan pada berbagai jenis fungsi polinomial, transenden, dan trigonometri—dengan membandingkan hasil pendekatan terhadap nilai eksak. Analisis dilakukan berdasarkan dua aspek utama, yaitu efektivitas (dilihat dari akurasi) dan efisiensi (dilihat dari waktu komputasi). Hasil penelitian menunjukkan bahwa metode Boole memiliki tingkat akurasi yang lebih tinggi dibandingkan metode Simpson 3/8. Rata-rata galat yang dihasilkan oleh metode Boole untuk fungsi polinomial, transenden, dan trigonometri masing-masing adalah , , dan . Sebaliknya, metode Simpson 3/8 mencatat galat rata-rata sebesar , , dan 8 pada fungsi-fungsi yang sama. Di sisi lain, metode Simpson 3/8 lebih efisien dalam hal waktu eksekusi, dengan rentang waktu antara 0,49200 ms hingga 0,605625 ms, dibandingkan metode Boole yang membutuhkan waktu antara 0,475125 ms hingga 0,776625 ms. Selisih waktu ini, meskipun kecil, menunjukkan bahwa Simpson 3/8 lebih cocok digunakan pada sistem yang memerlukan kecepatan respons tinggi.

Abstract

The philosophy of mathematics plays a crucial role in explaining the origins and status of mathematical knowledge. In the context of mathematics education, epistemological understanding is increasingly relevant, given the persistent dominance of absolutist views that regard mathematics as a certain and final body of knowledge. However, approaches such as empiricism and fallibilism offer alternative perspectives that are more reflective and dynamic. This study aims to explore the philosophical ideas of empiricism and fallibilism in mathematics and analyze their implications for mathematics education. The research employs a systematic literature review with a thematic analysis approach to identify key themes from each perspective and their potential contributions to educational practice. The findings reveal that empiricism emphasizes the role of concrete experience in the formation of mathematical knowledge, while fallibilism highlights the open and non-absolute nature of mathematical truth. The integration of these two approaches has the potential to support a contextual learning environment that embraces error and fosters critical thinking. Therefore, this study contributes theoretically to the development of mathematics education that is more humanistic, reflective, and centered on students' understanding.

Abstract

Impulsive buying is a consumer behavior that makes purchases without prior planning. Impulsive buying is one of the consumer behavior phenomena that is increasingly widespread, especially on e‑commerce platforms such as Shopee during massive promotions on beautiful dates. Multiple Discriminant Analysis (MDA) is a method that has the advantage of classifying individuals into groups based on several predictor variables. The purpose of this study is to classify consumers into groups or categories based on their tendency to make impulse purchases on beautiful dates by analyzing the factors that influence them. The results of this study indicate that the beautiful date can affect the behavior of impulsive buying. The discriminant function model formed is able to distinguish categories of impulsive buying behavior with a good classification accuracy rate of 86.25% and the model shows that price is the most dominant or influential factor in distinguishing the category of impulsive buying of Shopee users on beautiful dates. This means that MDA Modeling is very helpful in classifying respondents into groups or categories based on the factors that influence them.
