Abstract

This study aims to analyze students' math problem-solving skills based on gender. The subjects involved were 6 students of the Mathematics Education Department, where three of them were female and the rest were male. The instrument used is a description question on the topic of Three Variable Linear Equation System that adapted through PISA standard questions. The analytical tool used is the problem-solving stage introduced by Polya. The results showed that at the stage of understanding the problem, male students were more able to understand the questions and some of them were able to rewrite them based on their own words. At the stage of making a solution plan, all male subjects could make a mathematical model of the given problem as well as for two female subjects, while there was one female subject who was unable to make a mathematical model. At the stage of carrying out the plan, the three male subjects were again able to complete the plan properly, while the female subject still had difficulty solving the problems given. At the review stage, all male subjects had re-examined, while all female subjects did not reach this stage. In general, male subjects have better problem solving abilities than female subjects.

Abstract

This study aims to develop and evaluate a Problem Based Learning (PBL)-based Student Worksheet (LKPD) on polynomial material for 11th-grade students at SMAN 1 Lingsar. The development of the LKPD follows the modified 4-D model, which includes the Define, Design, and Develop stages, due to time and budget constraints. This research employs a one group pre-test and posttest experimental design, involving 30 11th grade students as subjects. The LKPD was validated by two experts: a content expert (80%) and a media expert (90%), who assessed aspects of content accuracy, instructional relevance, clarity, language, simplicity, visual design, and the integration of PBL components. The practicality of the LKPD was measured through questionnaires given to both teachers and students, with results showing a practicality level of 97% in terms of usability and instructional value. The effectiveness of the LKPD was tested through a mathematical literacy assessment given before and after the learning intervention. Data analysis was performed using a paired sample t-test, which showed a statistically significant improvement (p < 0.05) in students' mathematical literacy scores, particularly in problem formulation and solving indicators. These findings empirically support the use of the PBL model as a framework for designing instructional materials that can enhance mathematical literacy. The use of Canva as a design tool also increased student engagement through appealing and functional visual displays. The results of this study demonstrate that contextual and visually designed instructional materials can be effective pedagogical instruments, especially for abstract mathematics topics like polynomials. This research contributes to mathematics education by presenting a validated PBL based LKPD design model that can be adapted for various subjects and educational levels.

Abstract

Pengabdian ini bertujuan untuk meningkatkan kapasitas pedagogis guru matematika dalam mengembangkan perangkat ajar berbasis Ethno-STEM yang kontekstual dan berakar pada nilai budaya lokal. Permasalahan utama yang dihadapi mitra adalah rendahnya inovasi pembelajaran dan minimnya integrasi budaya lokal dalam perangkat ajar. Kegiatan ini dilaksanakan melalui model pelatihan dual-phase yang terdiri dari pelatihan in-service dan on-service dengan pendekatan deep learning. Metode ini memungkinkan guru untuk memperoleh pemahaman teoritis sekaligus menerapkannya dalam konteks nyata. Hasil kegiatan menunjukkan adanya peningkatan signifikan dalam kualitas perangkat ajar yang dikembangkan, keterlibatan aktif guru, serta kemampuan mengintegrasikan budaya lokal dalam pembelajaran matematika. Selain itu, pendekatan Ethno-STEM juga terbukti mendorong siswa berpikir kritis, kolaboratif, dan terlibat aktif dalam proses belajar. Dampak jangka panjangnya terlihat dari peningkatan pemahaman konseptual siswa dan keberlanjutan praktik pembelajaran berbasis budaya oleh guru setelah pelatihan. Pengabdian ini memberikan kontribusi nyata dalam pengembangan model pembelajaran kontekstual di tingkat SMP serta mendukung pencapaian Tujuan Pembangunan Berkelanjutan (SDGs), khususnya SDG 4 dan SDG 11. Assistance in Developing Ethno-STEM-Based Learning Materials to Optimize Student Learning Outcomes Abstract This community engagement aimed to enhance mathematics teachers' pedagogical capacity in designing contextual Ethno-STEM-based learning tools rooted in local cultural values. The main issue faced by partner schools was the lack of innovation and cultural integration in lesson plans. The program was implemented through a dual-phase training model consisting of in-service and on-service training with a deep learning approach. This method allowed teachers to gain theoretical understanding while practicing it in real classroom contexts. Results indicated a significant improvement in the quality of instructional tools, active teacher engagement, and their ability to integrate local culture into mathematics learning. Furthermore, the Ethno-STEM approach encouraged students to think critically, collaborate effectively, and participate actively in the learning process. In the long term, the program fostered conceptual understanding among students and empowered teachers to continuously implement culturally responsive teaching practices.  This program provides a practical contribution to the development of contextual learning models at the secondary school level and supports the achievement of Sustainable Development Goals (SDGs), particularly SDG 4 and SDG 11.
