Abstract

Students with different personality types have different levels of visual-spatial intelligence. One of them is a koleris student who has level 1 in the category of imagination and conceptualization. Visual-spatial intelligence is a part of spatial ability that is related to the ability of the brain. In this study, it will be described regarding the spatial abilities of koleris students which include the ability of spatial perception, spatial visualization, and mental rotation. The research subjects were students of class X MIPA 1 of SMAN 1 Jember who were classified as personality types based on the results of the questionnaire. Next, two students from the koleris type were given the spatial ability test questions and were interviewed to test the credibility of the students' answers. The results of the analysis of answers to the test questions and interviews will be described in full and then drawn conclusions. The results showed that the spatial ability profile of koleris students was able to fulfill all indicators of spatial perception, two indicators of spatial visualization, and two indicators of mental rotation. A good organizational system makes students koleris able to draw three-dimensional shapes well and correctly

Abstract

Higher Order Thinking Skills (HOTS) refer to students' ability to solve problems by analyzing, evaluating, and creating. HOTS are essential for 21st century learning. Solving combinatorics problem troubleshooting requires HOTS. The aim of this research is to examine of senior high school students’ higher order thinking skills in solving combinatorics problems. This descriptive research describes the analysis of senior high school students’ higher order thinking skills in solving combinatorics problems. Class XII IPA 6 SMA Negeri 1 Trenggalek has a total of 21 students. Data was collected through a written test containing combinatorics problems and interviews. The results of the study show the senior high school students’ higher-order thinking skills in solving combinatorics problems: 38% of the students have "excellent" performance; 14% are rated as good; 10% are classified as enough; 38% are classified as low; no one is very poor. The most common indicator of higher-order thinking skills was analyzing (58%), followed by evaluating (55%). The creating rate is the lowest at 47%. This study can develop students' higher order thinking skills and evaluation for teachers in implementing higher order thinking skills in school.DOI : https://doi.org/10.22342/jpm.16.1.15121.89-102

Abstract

Media pembelajaran merupakan penghubung dalam rangka memudahkan dalam pelaksanaan pembelajaran serta dapat meningkatkan keterampilan berpikir kreatif siswa terkait materi yang sedang dipelajari. Penelitian ini merupakan pengembangan media pembajaran yang menggunakan bantuan perangkat lunak Geogebra. Pemilihan Geogebra karena pada perangkat lunak ini memiliki tampilan sangat menarik serta sudah memiliki kelas tersendiri yaitu Geogebra Classroom yang dapat digunakan sebagai media untuk meyampaikan materi. Materi yang disampaikan pada media ini adalah materi persamaan lingkaran. Model pada penelitian ini menggunakan model Thiagarajan (model 4D). Model 4D memiliki empat tahap yaitu pendefinisian, perancangan, pengembangan, dan penyebaran. Subjek pada penelitian ini adalah siswa kelas XI MIPA 3 SMAN 3 Lumajang. Analisis pada penelitian ini dibagai menjadi tiga tahap. Pertama, tahap validasi yang dilakukan oleh dua dosen pendidikan matematika Universitas Jember dan satu guru mata pelajaran matematika SMAN 3 Lumajang yang menghasilkan kategori valid. Kedua, analisis kepraktisan ditunjukan dari angket respon pengguna yang berhasil mendapatkan kategori praktis. Ketiga, analisis keefektifan ditunjukan melalui hasil pengerjaaan soal pre-test dan post-test dengan menghasilkan kategori efektif. Berdasarkan hasil pre-test dan post-test siswa membuktikan bahwa media pembelajaran berbasis discovery based learning berbantuan geoegebra classroom dapat menigkatkan keterampilan berpikir kreatif siswa.

Abstract

Atherosclerosis is a leading cause of coronary heart disease. This study analyses how elliptically shaped stenoses alter blood-flow velocity in coronary arteries. The governing equations are discretised with the finite-volume method, coupling pressure and velocity through the SIMPLE (Semi-Implicit Method for Pressure-Linked Equations) algorithm and accelerating convergence with the Successive Over-Relaxation (SOR) technique. A weighted Gauss–Seidel iteration whose over-relaxation factor ( in this work) damps low-frequency error modes, cutting the number of iterations needed for residuals to fall below 10⁻⁴ by roughly 40 % compared with the standard Gauss–Seidel scheme. Simulations of 30 %, 50 %, and 70 % constrictions were carried out in MATLAB R2013a and ANSYS Fluent. Quantitative and qualitative cross-validation of the two software packages confirmed consistent velocity and pressure fields, though minor discrepancies arose from differing numerical schemes and model assumptions, underscoring the need for experimental verification. The highest centre-line velocity occurred at 70 % stenosis—0.72075 m/s in MATLAB versus 0.90 m/s in Fluent—while the lowest was recorded at 30 %. Velocity–pressure profiles showed that increasing inlet velocity or degree of narrowing elevates velocity but decreases pressure, with the largest drop (11492.4 Pa in MATLAB; 11747.32 Pa in Fluent) again at 70% stenosis. Study limitations include modelling blood as a Newtonian fluid and idealising arterial geometry; future work should incorporate non-Newtonian rheology and patient-specific shapes to enhance physiological accuracy.

Abstract

Abstrak Kemampuan pemecahan masalah matematis merupakan salah satu kompetensi penting yang harus dimiliki oleh siswa, dan kepercayaan diri diyakini memiliki kontribusi signifikan terhadap pencapaiannya. Penelitian ini bertujuan untuk mengetahui hubungan antara kepercayaan diri (self-confidence) dan kemampuan pemecahan masalah matematis siswa SMP. Penelitian ini menggunakan metode kuantitatif dengan desain korelasional. Subjek penelitian adalah 87 siswa kelas VIII di SMP Negeri 12 Jember pada semester genap tahun ajaran 2023/2024. Data dikumpulkan melalui angket kepercayaan diri dan tes kemampuan pemecahan masalah matematis. Berdasarkan analisis deskriptif, nilai rata-rata kepercayaan diri siswa adalah 96,08 dengan kategori dominan berada pada tingkat sedang (74,71%). Hasil analisis korelasi menunjukkan terdapat hubungan yang positif antara kepercayaan diri dan kemampuan pemecahan masalah matematis. Kesimpulan dari penelitian ini adalah semakin tinggi tingkat kepercayaan diri siswa, maka semakin baik kemampuan mereka dalam menyelesaikan soal-soal matematika secara problematis. Implikasi dari temuan ini menunjukkan pentingnya strategi pembelajaran yang tidak hanya fokus pada aspek kognitif, tetapi juga afektif siswa, seperti penguatan rasa percaya diri guna mendukung keberhasilan akademik, khususnya dalam pembelajaran matematika. Abstract Mathematical problem-solving ability is one of the essential competencies students must possess, and self-confidence is believed to significantly contribute to its achievement. This study aims to determine the correlation between self-confidence and junior high school students’ mathematical problem-solving ability. The research employed a quantitative method with a correlational design. The subjects were 87 eighth-grade students at SMP Negeri 12 Jember during the even semester of the 2023/2024 academic year. Data were collected through a self-confidence questionnaire and a mathematical problem-solving test. Based on descriptive analysis, the average self-confidence score was 96.08, with the majority (74.71%) falling into the average category. The results of the correlation analysis showed a positive relationship between self-confidence and mathematical problem-solving ability. The conclusion of this study indicates that the higher the level of students’ self-confidence, the better their ability to solve mathematical problems. The implications of these findings highlight the importance of learning strategies that focus not only on cognitive aspects but also on students’ affective domains, such as enhancing self-confidence to support academic success, particularly in mathematics learning.
