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.

Abstract

Masalah (problem) adalah suatu kesenjangan atau perbedaan dalam situasi sekarang dan apa yang terjadi. Masalah yang terjadi bisa saja bersifat universal dimana situasi yang sama juga akan terjadi untuk semua orang atau mungkin secara khusus kepada individu atau sekelompok orang tertentu. Konsep pemecahan masalah (problem-solving) menjadi satu pendekatan baru yang berkembang untuk menjadi solusi dalam menyelesaikan masalah dalam pembelajaran matematika. Akan tetapi, beberapa penelitian yang berkaitan dengan proses pemecahan masalah matematis menunjukkan bahwa belum banyak guru yang menerapkan pendekatan pemecahan masalah dalam pembelajaran di kelas. Oleh karena itu, tujuan dari kegiatan pengabdian kepada masyarakat yang akan dilakukan ini adalah melaksanakan suatu pelatihan kepada guru matematika untuk mampu menerapkan berbagai strategi dalam pemecahan masalah matematis. Metode pengabdian dilakukan dengan pemodelan dimana tim pengabdian kepada masyarakat mendemonstrasikan teknik dan strategi pemecahan masalah, selanjutnya dilakukan simulasi dengan memberikan beberapa problem yang harus diselesaikan oleh guru matematika yang tergabung dalam MGMP Muaro Jambi. Kegiatan pengabdian kepada masyarakat telah dilaksanakan pada tanggal 18 September 2024 di SMP Negeri 30 Muaro Jambi. Peserta yang hadir dalam kegiatan ini adalah guru matematika yang berjumlah 27 orang yang merupakan guru MGMP Matematika SMP Kabupaten Muaro Jambi dengan informan (narasumber) adalam tim pengabdian kepada masyarakat Prodi Pendidikan Matematika FKIP UNJA. Hasil pengabdian menunjukkan bahwa guru dapat meningkatkan kemahiran mereka dalam pemecahan masalah yang pada akhirnya memberdayakan mereka untuk menumbuhkan keterampilan berpikir kritis pada siswa secara efektif. Berdasarkan data hasil pengabdian, dapat disimpulkan bahwa perlu terus dikembangkan strategi pemecahan masalah yang dilakukan oleh guru agar keterampilan berpikir matematis siswa semakin meningkat.

Abstract

This research investigates the combined influence of scientific attitude, active learning, and friendly character on the science learning outcomes of junior high school students in Kota Jambi. It explores how these factors contribute to student's academic performance and social development in science education. A mixed-methods approach was used, integrating quantitative data from questionnaires with qualitative insights from interviews. The sample consisted of junior high school students in Kota Jambi. Data analysis was performed using multiple regression tests with SPSS to examine the relationship between the variables. The results indicate that scientific attitude, active learning, and friendly character significantly and positively affect students' science learning outcomes. Active learning enhanced students’ engagement and critical thinking skills, while a strong scientific attitude improved their curiosity and problem-solving abilities. Students with well-developed, friendly character traits also demonstrated better social interactions, leading to more effective collaboration in group-based learning activities. Despite these positive outcomes, the study highlights the challenge of translating scientific concepts into real-world applications, which requires greater emphasis on contextual learning and motivation. This study offers a fresh perspective by integrating social-emotional traits such as friendly character into analyzing science learning outcomes, an area often overlooked in previous research. It provides actionable insights into how fostering active learning and positive social interactions can create a more engaging and effective science learning environment.

Abstract

This study aims to analyze and describe students' intuitive thinking abilities in solving mathematical problems on the topic of integers. This research employs a qualitative descriptive method. One research subject (S1) will be selected using purposive sampling based on their ability to demonstrate initial indications of intuitive thinking, such as the accuracy and speed of their initial response to a problem. The research instrument consists of one integer problem-solving test question designed to assess intuitive thinking abilities. Data is collected through triangulation using the think-aloud technique during the problem-solving process, followed by a semi-structured interview to explore the subject's (S1) reasoning and intuitive thought processes. Data is analyzed qualitatively through the stages of data reduction, data presentation, and conclusion drawing. The results reveal that intuition, specifically the common-sense type, acts as a cognitive bridge that accelerates the emergence of ideas and the formulation of problem-solving strategies. This intuitive thinking characteristic is demonstrated through the application of systematic strategies, logical reasoning, and a strong reliance on prior learning experiences. These findings indicate that learning experiences can serve as a crucial foundation in forming effective mathematical intuition. Therefore, mathematics instruction should be designed to enrich student experiences through a variety of problem-solving tasks to develop students' intuitive thinking abilitie

Abstract

Schools play a critical role in enabling students to discover, develop, and express their creative potential. However, instructional practices that explicitly promote students’ creative thinking skills in mathematics learning remain limited. Therefore, this study aims to examine and describe the creative thinking processes of junior high school students in solving mathematical reasoning problems. This study employed a qualitative case study design involving 35 eighth-grade students. A mathematical reasoning test was administered to identify students’ levels of creative thinking. Based on the results, four students representing different categories of creative thinking (imitative, routine, creative, and very creative) were purposively selected as research subjects. Data were collected through students’ written work, in-depth interviews, and document analysis. The findings indicate that each category demonstrates distinctive characteristics in terms of problem-solving strategies, flexibility of ideas, and originality in constructing solutions. Students in the higher creative categories tended to generate multiple strategies and more original solution processes. These findings emphasize the importance of designing mathematics learning activities that encourage exploration of diverse strategies, idea generation, and reflective thinking.

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

 Rapor Pendidikan diluncurkan Kemdikbud pada 2022 untuk menampilkan profil mutu satuan pendidikan dan menjadi dasar perencanaan berbasis data. Hasil rapor digunakan sekolah untuk refleksi, analisis, perencanaan, dan tindak lanjut peningkatan mutu secara berkelanjutan. Perencanaan berbasis data juga mendorong penggunaan anggaran yang efektif, akuntabel, dan tepat sasaran. Namun, tidak semua sekolah dasar di Kecamatan Tebo Tengah menunjukkan capaian yang baik. Beberapa sekolah mengalami penurunan nilai rapor pendidikan tahun 2024 dibanding 2023, bahkan masih terdapat kategori merah atau kurang. Kondisi ini dipengaruhi oleh ketidaksiapan siswa menghadapi Asesmen Nasional, metode mengajar guru yang masih konvensional, serta program sekolah yang belum sesuai data riil. Karena itu, kepala sekolah membutuhkan pendampingan untuk menyusun strategi peningkatan rapor pendidikan dan perencanaan berbasis data. Program pengabdian dilaksanakan selama delapan bulan melibatkan pengawas, kepala sekolah, dan guru. Hasilnya, peserta mulai memahami indikator rapor pendidikan serta mampu merancang tindak lanjut sesuai kebutuhan siswa di masing-masing sekolah dengan lebih terarah dan sistematis. Abstract.  The Education Report Card was launched by the Ministry of Education in 2022 to present the quality profile of schools and serve as a basis for data-driven planning. The report results are used by schools for reflection, analysis, planning, and follow-up actions to improve quality sustainably. Data-based planning also encourages effective, accountable, and targeted budget use. However, not all elementary schools in Central Tebo District showed good performance. Some schools experienced a decline in their 2024 report card scores compared to 2023, and several remained in the red or low category. This condition was caused by students’ lack of readiness for the National Assessment, teachers still using conventional teaching methods, and school programs not aligned with actual data. Therefore, principals needed assistance in designing strategies to improve education report cards and data-based planning. The community service program was conducted for eight months involving supervisors, principals, and teachers. As a result, participants began to understand the report indicators and were able to design follow-up actions according to students’ needs in each school more systematically.

Abstract

The low level of mathematical problem-solving skills among junior high school students necessitates effective heuristic-based instructional strategies. This quasi-experimental study, employing a pretest-posttest two-group design, aimed to compare the effectiveness of the Decomposing-Recombining (DR) and Working Backwards (WB) approaches on Linear Equations and Inequalities in One Variable. The research sample consisted of 49 eighth-grade students (DR: N=24, WB: N=25) in Muaro Jambi, selected through purposive sampling. Instruments included mathematical problem-solving tests and instructional observation sheets. Results indicated that the DR approach met all effectiveness criteria, achieving a post-test mean score of 78.47 and a high-category improvement (N-Gain significantly exceeding 0.70, p < 0.05). Conversely, the WB approach only reached a moderate improvement with a post-test mean of 53.72. The Mann-Whitney U test confirmed a significant difference in effectiveness between the two groups (Z = -4.091, p < 0.001), with the DR approach consistently outperforming WB in enhancing problem-solving abilities. This study concludes that the DR approach is a more effective explicit instructional strategy for strengthening students' conceptual and procedural mathematical structures.

Abstract

Students often struggle to express mathematical ideas through multiple external representations, particularly when learning polyhedral geometry that requires coordination of visual, verbal, and symbolic forms. This study aims to design a project-based learning worksheet and examine its validity and feasibility through the Geometrocity project. In this activity, students construct a miniature city as a contextual medium to explore geometric concepts while engaging with structured representational tasks. The study follows the ADDIE development framework and is limited to the development stage. The focus lies on producing a valid and feasible learning tool rather than measuring classroom effectiveness. Two material experts and one media expert evaluated the worksheet using validation instruments that assess content accuracy, language clarity, instructional presentation, and graphical design. Quantitative ratings were analyzed using descriptive statistics, while qualitative feedback supported iterative product revisions. The results indicate that the Geometrocity worksheet achieved high validity scores across all assessed aspects and met the criteria for feasibility. These findings suggest that the worksheet is suitable for use in further implementation studies. This study contributes a project-based worksheet that integrates structured representational activities within contextual geometry tasks.

Abstract

The rapid development of artificial intelligence (AI) in education has created new opportunities to enhance students’ mathematical conceptual understanding and support more personalized learning experiences. This study aims to explore students’ mathematical conceptual understanding when using AI chatbots in learning the Pythagorean Theorem. This study employs a descriptive qualitative approach, involving eighth-grade junior high school students selected through purposive sampling based on their level of conceptual understanding. Data were collected through a perspective questionnaire, an essay-based test, and semi-structured interviews, and analyzed using data reduction, data presentation, and conclusion drawing. The findings reveal that students were able to meet all indicators of mathematical conceptual understanding, with AI helping them understand definitions, visualize geometric relationships, obtain immediate feedback, and recognize real-world applications of the Pythagorean Theorem. However, students still face difficulties in meeting some of the indicators of mathematical conceptual understanding in the Pythagorean theorem, which were influenced by a tendency to rush and the suboptimal use of AI features. In conclusion, although AI can effectively support conceptual understanding, its integration in learning should be accompanied by teacher guidance to foster metacognitive awareness and deeper, more reflective learning.
