Abstract

Learning concentration plays a crucial role in students' academic success and can be influenced by various factors, including sleep quality. This study examines the relationship between sleep quality and mathematics learning concentration among seventh-grade students (VII-3) at SMPN 4 Medan. A descriptive correlational method with a quantitative approach was used. Data were collected using a sleep quality questionnaire based on the Pittsburgh Sleep Quality Index (PSQI) and a learning concentration questionnaire. Statistical analysis included the Chi-Square test, Pearson and Spearman correlation, and Odds Ratio estimation. Results showed that 54.5% of students had poor sleep quality, while 45.5% had good sleep quality. Regarding concentration, 54.5% of students exhibited good concentration, while 45.5% struggled to focus. Statistical tests confirmed a significant relationship between sleep quality and learning concentration (p = 0.007), with a moderate positive correlation (r = 0.467). The Odds Ratio indicated that students with good sleep quality were eight times more likely to have high concentration. These findings emphasize the importance of proper sleep habits in improving students' focus and academic performance.

Abstract

Penelitian ini merupakan kajian literatur sistematis yang bertujuan untuk mengevaluasi efektivitas pendekatan open-ended problem terhadap kemampuan pemecahan masalah dan berpikir kreatif matematis siswa. Kajian dilakukan terhadap 30 artikel terpilih yang diperoleh dari berbagai database ilmiah. Metode analisis yang digunakan adalah content analysis dengan klasifikasi berdasarkan jenjang pendidikan, konteks geografis, pendekatan metodologis, serta dimensi kemampuan yang dikaji. Pada tingkat SD hingga perguruan tinggi, pendekatan open-ended problem efektif dalam menumbuhkan kemampuan berpikir kreatif dan pemecahan masalah, mulai dari eksplorasi ide, keterampilan analisis, refleksi, dan fleksibilitas. Secara geografis, penelitian luar negeri cenderung mengadopsi pendekatan yang lebih beragam dan inovatif dengan hasil yang konsisten positif, sementara penelitian dalam negeri juga menunjukkan efektivitas yang baik meski masih menghadapi beberapa tantangan. Hasil kajian menunjukkan bahwa open-ended problem secara umum efektif dalam meningkatkan kemampuan pemecahan masalah dan berpikir kreatif siswa. Faktor yang paling berpengaruh terhadap efektivitasnya meliputi kualitas perancangan soal, kompetensi guru, serta keterlibatan aktif siswa dalam proses pembelajaran. Studi ini merekomendasikan integrasi open-ended problem dalam praktik pembelajaran matematika untuk menumbuhkan keterampilan berpikir tingkat tinggi.

Abstract

This study aims to determine the effect of problem-based learning model on students' mathematical critical thinking skills. The population of this study is all seventh grade students of SMP Negeri 1 Natar even semester of the 2023/2024 academic year as many as 371 students distributed into eleven classes, namely VII A to VII K. Sampling was carried out using purposive sampling technique, so that VII A class of 34 students was selected as the experimental class and VII D of 33 students as the control class. The design used was pretest-posttest control group design. The data in this study are quantitative data obtained through the mathematical critical thinking ability test. Based on the Mann-Whitney U test results, it was found that the improvement in mathematical critical thinking skills of students who participated in learning with problem-based learning was higher than the improvement in mathematical critical thinking skills of students who participated in conventional learning. In addition, based on the results of the proportion test, it was found that more than 60% of students who participated in problem-based learning were categorized as good. So it can be concluded that the problem-based learning model has an effect on students' mathematical critical thinking skills.

Abstract

Aljabar Lie dari grup Lie Aff(n,R) dinotasikan oleh aff(n,R)  di mana setiap anggotanya dapat dinyatakan dalam bentuk matriks berukuran (n+1) x (n+1). Sifat Frobenius ini mengakibatkan adanya Frobenius fungsional yang bekorepondensi dengan bentuk simplektiknya.  Tujuan penelitian ini adalah untuk menentukan bentuk simplektik pada aff(3,R). Pendekatan yang digunakan dalam penelitian ini adalah kombinasi dari metode kuantitatif berupa penentuan rumus eksplisit simplektik linear 2-form pada aff(3,R) dan metode kualitatif berupa studi literatur. Hasil yang diperoleh bahwa setiap  Frobenius fungsional dari aljabar Lie affine  senantiasa dapat dikonstruksi simplektik 2-form linear yang bersifat skew-simetrik dan non-degenerate sedemikian sehingga aljabar Lie affine aff(3,R) ini bersifat Frobenius. Hasil penelitian ini dapat dikembangkan untuk rumus umum bentuk simplektik aff(n,R), n>=4.

Abstract

Numerical methods play a crucial role in solving non-linear equations that cannot be solved analytically. This study compares the use of two software tools, Matlab and Maple, in determining the roots of non-linear equations using the bisection method. This method iteratively divides the root search interval into two parts until the specified error tolerance is reached. The research employs a descriptive qualitative approach, where two non-linear equations are tested using Matlab and Maple. The analysis results show that both software tools provide nearly identical outputs, with minimal differences due to variations in numerical representation. Matlab excels in numerical programming flexibility and data visualization, while Maple is easier to use as it has built-in functions for the bisection method. The findings of this study are expected to provide insights for users in selecting appropriate software to solve numerical method problems.

Abstract

Statistics is often considered a challenging subject, where high levels of anxiety can hinder understanding of the material, affect results, and hinder the development of statistical skills. This study aims to analyze effectiveness of four learning strategies namely tutorial learning, presenter learning, project online learning, and project face to face learning in improving students' statistical literacy skills. This study used a quantitative approach with a posttest group design research design involving 140 students who were divided into four treatment groups. The analysis technique used is MANOVA (Multivariate Analysis of Variance) with the stages of normality test, homogeneity, multiple comparisons, and Tukey HSD further test. The results show that Tutorial Learning, Presenter Learning, and Project Face to Face Learning strategies have a more significant impact on improving statistical literacy. The three strategies showed relatively balanced effectiveness in improving students' statistical skills. This finding confirms the importance of selecting appropriate learning strategies to promote a deep and meaningful understanding of statistics. This research provides an empirical contribution to the development and selection of appropriate learning strategies, especially in statistics education at the tertiary level. It also recommends further exploration of innovative, contextual, and adaptive combinations of learning strategies to students' needs.
