Abstract

Mathematics is a learning whose material is abstract. This causes students to find it difficult to understand mathematics, feeling that mathematics is difficult and boring. This condition occurred at Karitas Watuneso Vocational School. This Community Service aims to provide socialization and innovation in mathematics learning using trigonometry as a medium so that it is hoped that students will be more able to understand and be interested in learning mathematics. The results of the service with questionnaires that have been filled in by students show that the use of trigonometry teaching aids in their learning is 85% strongly agree and 15 percent agree, the method of delivering the material is 88% strongly agree and 12% agree, and students' understanding of the use of learning media is 80% strongly agree and 20% agree, while how to use it, 85% strongly agree and 15% agree. Thus, it can be concluded that students feel that the use of trigonometry teaching aids can facilitate students' understanding of trigonometry material and students are enthusiastic in this activity.

Abstract

In the ever-evolving digital era, education faces unprecedented challenges and opportunities. Technology is now an integrated part of the learning process, providing various tools that can increase the effectiveness and efficiency of education. One technological innovation that has great potential to support educators is ChatGPT. This ability can be utilized by teachers for various purposes, including in making learning tools. With the help of ChatGPT, teachers can save time and energy in designing teaching materials, assignments and learning evaluations that suit students' needs (Kharis et al., 2024). The teachers at SMP PGRI 8 Sidoarjo have not made much use of technology that makes it easier for them to prepare learning tools. This can be seen from the results of initial observations which show that 71.4% of teachers have never used applications or technology that makes it easier to create learning tools. This Community Service implementation was carried out with the aim of introducing, socializing and assisting teachers in utilizing ChatGPT to develop learning tools more quickly, effectively and efficiently. The results of participant responses regarding the implementation of activities are measured by participant satisfaction, which is the average of participant satisfaction with the satisfaction indicator factors. In this activity, 84.46% of participants gave an average rating of very good to the statement items in the questionnaire, which can be interpreted as meaning that 84.46% of participants were very satisfied.

Abstract

As a maritime nation with significant marine potential, integrating maritime contexts into secondary education in Indonesia is essential for preparing students to understand mathematical concepts and their applications in various maritime professions. To support this goal, we developed scietific numeracy tasks by integrating maritime concepts. We designed the tasks based on a literature review related to maritime concepts and referred to the PISA framework, which was then realized in the form of a maritime numeracy conceptual framework. This framework consists of four main subcontexts: navigation, marine engineering, oceanography, and maritime economics. We developed tasks for each subcontexts, which were evaluated by three experts. The experts validated based on relevance of the maritime context, involvement of maritime concepts, suitability in measuring numeracy, and quality of the tasks from pedagogical aspect. The evaluation results showed that the quality of the tasks was in the very good category in all aspects, with a moderate and good level of agreement among the experts, indicated by the interclass correlation coefficient score of 0.538. This research is expected to contribute to the innovation of numeracy task design with scientific contexts that specifically accommodate maritime concepts and support efforts to improve students’ numeracy in Indonesia.

Abstract

The method used in this study is Classroom Action Research (CAR) using teaching aids to find out whether there is an increase in learning outcomes and the motivation of students in class VI SD Inpres Lisabheto in mathematics, especially material building. Based on the pre -survey results, explaining that many student learning outcomes in pre -cycles have not yet reached the KKM, as well as the low motivation to learn students. This can be seen at the first meeting with an average learning outcome of 65.85 completeness level of 50% and the second meeting averaged 75.78 disjolized 1 so that the completeness level of 68.75%. Because there are learning outcomes that have not yet reached the KKM, they will be continued. On average in the second cycle the first meeting was 90.01 completeness level of 100% and at the second meeting an average of 95.63 with a completeness level of 100%. In this second cycle it has reached KKM with a value of ? 66. While the motivation of student learning in the first cycle with an average of 49.9 and the second cycle reaches 62.8. Based on the average learning motivation in cycle 1 and cycle 2 it can be concluded that the media of teaching aids can affect student motivation so that it provides maximum learning outcomes after evaluating class VI at SD Inpres Lisabheto Academic Year 2021/2022

Abstract

Kehidupan sehari-hari sangat bergantung pada matematika (Tasar et al., 2018). Berdasarkan hasil wawancara siswa SMPN 1 Waigete, matematika sering dianggap oleh siswa sebagai mata pelajaran yang menantang dan membosankan. Untuk menjawab permasalahan dalam matematika, seseorang harus mampu berpikir kritis (Rahmawati et al., 2024). Model pembelajaran kooperatif metode make-a-match merupakan salah satu strategi pembelajaran matematika yang harus dikembangkan agar dapat membantu siswa dalam memahami konsep matematika dan mengidentifikasi hubungan yang bermakna dalam menyelesaikan masalah. Oleh karena itu tujuan penelitian ini adalah untuk mengetahui apakah ada pengaruh model pembelajaran make a match iterhadap pemahaman konsep matematika siswa kelas VII di SMPN Waigete. Menggunakan metode penelitian kuantitaif dengan menguji hipotesis didapatkan hasil bahwa nilai t hitung yang diperoleh dari perhitungan uji-t adalah sebesar 2,52. Dengan derajat kebebasan (db) = 53 dan taraf signifikansi (α) = 0,05, maka nilai t tabel yang diperoleh dari tabel tersebut adalah 1,67. Seperti yang ditunjukkan oleh hasil perbandingan antara t hitung dan t tabel, t hitung lebih besar dari t tabel. Ini menunjukkan bahwa pendekatan pembelajaran Make A Match mempengaruhi pemahaman konsep matematika siswa SMPN 1 Waigete.

Abstract

Adaptive assessment systems depend on question banks whose difficulty rises in a credible way and whose items can distinguish learner performance. This study reports the design and validation of a 90-item question bank for adaptive learning in maritime mathematics at Politeknik Pelayaran Surabaya. The bank covered six STCW-aligned topics (speed-distance-time, ETA calculation, compass correction, great circle navigation, tidal height, altitude correction), arranged them across three progressive difficulty levels, and linked them to an AI-tutor system using a 2-up/2-down adaptive staircase algorithm. Validation had two parts. The maritime mathematics curriculum committee first conducted an expert pedagogical audit with a rubric covering curriculum alignment, difficulty progression, answer correctness, and linguistic clarity. Simulated pilot testing with synthetic learner profiles was then used to check whether the adaptive engine behaved as expected. In that audit, 15 of 90 items needed revision, mainly for clarity and difficulty calibration, while 75 were retained without modification. After revision, the bank still showed a balanced spread across topics and difficulty levels and maintained appropriate content validity. Simulation results likewise confirmed the intended pattern: difficulty shifted only after two consecutive correct or incorrect responses. For that reason, expert review paired with simulation offers a workable validation route for adaptive assessment systems in specialized vocational education contexts, especially when large-scale learner pilot testing is not yet feasible.
