Abstract

This research aims to increase students' self-confidence in learning mathematics through the "numeracy literacy" program as part of the Teaching Campus initiative. The research method used was qualitative with a library study approach and direct observation at SMP Negeri 5 Sorong City. Initial observations show that interest in studying mathematics in grade 8 students is very low, as reflected in the low level of visits to the school library. The numeracy literacy program is carried out in groups, where students work on numeracy questions and then read the results of their work aloud and with the right intonation. The research results showed that after two weeks of implementing the program, there was a significant increase in self-confidence and interest in learning mathematics, as well as being able to read clearly and loudly, as well as the ability to speak in public. Apart from that, students' self-confidence in expressing opinions and speaking in public also increases. In conclusion, the numeracy literacy program is effective in increasing students' interest in learning mathematics and self-confidence. This program supports national education goals by making the nation's life smarter and realizing social justice through equitable and integrated education. The Teaching Campus Program, as part of Merdeka Belajar, plays an important role in assisting the teaching and learning process in schools and increasing student competency.

Abstract

This study aims to analyze the errors made by Grade XI students of SMA Teknologi Kota Sorong in solving inverse function problems and to identify the factors causing these errors. The approach used is qualitative with a descriptive method, where data were obtained through diagnostic essay tests and observations of 15 students. The analysis results show that students' errors fall into four main categories: conceptual errors at 7%, principal errors at 7%, factual errors, which dominate with a percentage of 47%, and operational errors at 20%. A total of 20% of students were able to answer all questions correctly. The primary causes of errors include a lack of understanding of the basic concept of inverse functions, improper application of formulas, and inaccuracy during calculations. External factors such as ineffective teaching methods and low student motivation further exacerbate the level of errors that occur. This study provides important contributions to the development of more effective learning strategies, helping teachers create a more meaningful mathematics learning process that focuses on students' comprehensive understanding.

Abstract

A preliminary analysis at SMA Muhammadiyah Al Amin Sorong identified limited use of interactive learning media, low student engagement, and insufficient integration of Islamic values in mathematics learning. Therefore, this study aimed to develop an interactive digital mathematics module based on Problem-Based Learning (PBL) and integrated with Islamic values for grade XI students studying regression analysis. The study employed the ADDIE development model, consisting of Analyze, Design, Development, Implementation, and Evaluation stages. The study involved 42 eleventh-grade students, consisting of 10 students in a small-group trial and 32 students in a large-group trial. Data were collected using expert validation sheets, student response questionnaires, a single pretest-posttest assessment instrument, student activity observation sheets, and questionnaires measuring problem-solving skills and Islamic character. The module was validated by three experts in material, media, and language. The validation results showed high validity, with scores of 0.92 for media, 0.89 for language, and 0.85 for material. The practicality results showed average scores of 84% in the small-group trial and 92.5% in the large-group trial, categorized as practical and very practical, respectively. The effectiveness analysis showed a significant difference between pretest and posttest scores (p < 0.05), with an average N-Gain of 67.06%, categorized as moderately effective. Student activity observations indicated engagement in group discussions, problem-solving activities, and responsibility, while questionnaire results showed 90% for Islamic character and 88% for problem-solving skills, both categorized as very effective. Because the study used a one-group pretest-posttest design without a control group, these findings provide preliminary evidence that the module can support improvements in students’ learning outcomes and problem-solving performance while fostering Islamic character. Further research using a control or comparison group is needed to confirm its effectiveness.
