Abstract

Penelitian ini berlatarbelakang pada rendahnya kemampuan pemecahan masalah matematis karena kurang optimalnya pelaksanaan pembelajaran. Penelitian ini tujuannya untuk mendeskripsikan proses serta kualitas hasil dari desain produk berupa media pembelajaran berbasis STEM Design Thinking berbantuan video animasi untuk meningkatkan kemampuan pemecahan masalah matematis siswa. Penelitian ini menerapkan metode R&D beserta model pengembangan ADDIE. Instrumen yang dipergunakan yakni angket validitas desain dan materi, angket praktikalitas untuk guru dan siswa, angket efektivitas untuk siswa, serta tes kemampuan pemecahan masalah matematis. Penelitian dilaksanakan di SMP Islam Al-Falah Jambi dengan siswa kelas VII 1 sebagai subjek penelitiannya. Penelitian ini menghasilkan bahwa media pembelajaran berbasis STEM Design Thinking berbantuan video animasi telah teruji kualitasnya meliputi kevalidan, kepraktisan, serta keefektifan. Media pembelajaran dinyatakan layak digunakan di mana persentase skor penilaian 93,03% pada kriteria sangat valid untuk aspek kevalidan, 88,51% pada kriteria sangat praktis untuk aspek kepraktisan, dan 84,09% pada kriteria sangat efektif untuk aspek keefektifan. Selain itu, keefektifan juga diukur melalui analisis N-Gain di mana didapat angka N-Gain senilai 0,63 atau 63% dengan kriteria cukup efektif. Jadi, kriteria kualitas produk berupa valid, praktis, maupun efektif terpenuhi, karenanya media pembelajaran layak digunakan dalam pembelajaran matematika.AbstractThe foundation of this research bolstered by the low ability of mathematical problem solving because the learning implementation has not been ideal. This research’s purpose is to describe the process and quality of product development result in the form of STEM Design Thinking-based learning media assisted by animated videos to increase students’ mathematical problem solving ability. This research is using R&D method with ADDIE development model. The used research instruments are design and material validity questionnaire, practicality questionnaire for teacher and students, effectivity questionnaire for students, and mathematical problem solving ability tests. This research was held in SMP Islam Al-Falah Jambi with students of class VII 1 as the research subjects. The results of this research are concluded that quality of STEM Design Thinking-based learning media assisted by animated videos has been tested, including the validity, practicality, and effectivity. The developed learning media deserve to be used with the percentage of assessment score reached 93,03% with the very valid criteria for the validity aspect, 88,51% with the very practical criteria for the practicality aspect, and 84,09% with the very effective criteria for the effectivity aspect. Besides that, the effectivity is measured by N-Gain analysis too and the N-Gain value obtained is 0,63 or 63%, so the learning media is effective enough to increase students’ mathematical problem solving ability. Therefore, learning media meets the criteria of being valid, practical, and effective so it is worthy to be used mathematics learning.

Abstract

This research aims to increase students’ speaking ability by using flashcard props (picture cards). The method used is qualitative. The sample of this research is the students of class V SDN 205/IV Jambi, Academic Year 2022/2023. The results showed an increase in English speaking skills, which refers to the results of the final test and interviews given to students. Thus, the use of contextual learning models assisted by flashcards can improve the English speaking skills of students in class V SDN 205/IV Jambi.

Abstract

This qualitative study explores Perseverance in Mathematical Reasoning (PiMR) in a junior high school student while solving a Data Presentation problem. A qualitative approach was chosen to gain an in-depth and contextual understanding of the subject's reasoning process and behaviors. The background for this study is the low level of mathematical reasoning perseverance among Indonesian students, which is a crucial ability. This study used a PISA-model written test and an interview with one seventh-grade subject. Data were analyzed using the Miles and Huberman model through data reduction, data display, and conclusion drawing. In general, the subject successfully demonstrated some indicators of PiMR, such as exploring solutions and attempting to correct answers. However, the main finding reveals the subject's inability to adjust strategies when facing an impasse, which resulted in the final answer remaining incorrect. The implication of this research emphasizes the need for targeted educational support to develop mathematical reasoning perseverance in students that is not only persistent but also more adaptive and sustainable.

Abstract

This study aims to analyze the development of publications on mathematical connections in Indonesia from 2020 to 2025. A total of 91 articles were analyzed using a bibliometric approach based on metadata obtained from Google Scholar, SINTA, and national journal databases. The analysis focused on annual publication trends, productive journals and their indexation status, research methods, educational levels examined, and dominant keywords. The findings show an increase in publications over the last five years, especially in 2023–2024. Most articles were published in national journals indexed by SINTA, while publications in international indexed journals remain limited. The dominant research method was qualitative-descriptive (52 articles), followed by quantitative (22 articles), mixed methods (5 articles), R&D (5 articles), and literature review (7 articles). Junior high school/MTs was the most researched education level, with 47 articles, followed by high school with 34, while research at the elementary and higher education levels was still limited. The most dominant keywords used were mathematical connections and mathematical connection ability, along with problem-solving and contextual learning. This study highlights mathematical connections as an important focus in mathematics education research in Indonesia and suggests further exploration across varied education levels and methodologies.

Abstract

This study investigates the strategic use of Duolingo as an interactive learning medium to enhance oral communication skills among vocational high school students. Employing a mixed-methods convergent parallel design, data were collected from 30 students and two English teachers through pre- and post-speaking tests, motivation and engagement questionnaires, classroom observations, and semi-structured interviews. The data were analyzed using complementary quantitative and qualitative techniques. The quantitative results demonstrated significant improvements across all speaking dimensions, with the most tremendous gains in communicative competence (M gain = +1.6). The questionnaire findings revealed high levels of motivation and engagement, driven by Duolingo's gamification features, although self-regulation remained a challenge. Qualitative data confirmed that students developed greater confidence and improved vocabulary retention, while teachers emphasized the benefits of integrating Duolingo with communicative tasks, such as role-playing and group discussions. Classroom observations further indicated progressive increases in participation, vocabulary use, and enthusiasm throughout the intervention. These findings suggest that Duolingo is most effective when strategically embedded within interactive classroom practices, aligning with the Merdeka Belajar curriculum by fostering learner autonomy, motivation, and communicative competence. This research offers a novel contribution by demonstrating that, despite these challenges, the effectiveness of technology-enhanced learning ultimately hinges on the overlooked yet critical roles of teacher mediation and institutional support.
