Abstract

This research is motivated by the low utilization of technology in mathematics learning. Although students are accustomed to using digital devices such as smartphones, the reality in the field still shows obstacles in optimally implementing technology. Therefore, innovative learning media are needed to utilize technology optimally and attract student learning interest, one of which is through e-learning platforms such as Desmos. This study aimed to determine the effectiveness of the application of Desmos learning media on students' mathematics learning outcomes in the quadratic function material of class X of SMA Negeri 5 Palangka Raya. This research was conducted in May 2025. The subjects of this study were 36 students of class X-2 of SMA Negeri 5 Palangka Raya in the even semester of the 2024/2025 academic year. This type of research uses applied research with qualitative and quantitative data analysis. Data collection techniques were carried out through observations of teacher and student activities, student response questionnaires, and written tests. The results of the study showed that the use of Desmos in learning quadratic functions positively impacted student learning outcomes. The average final test score reached 80.3%, with a classical completion rate of 80%, and student responses to Desmos were in the "good" category, with an average of 72.83%. Based on these results, Desmos has been proven to increase student active engagement and understanding of quadratic functions.

Abstract

A lesson study is a plan of models, strategies, approaches, methods, and techniques effectively implemented in the classroom. The objectives of community service activities are as follows: Assist mathematics teachers in creating learning tools through lesson plans, LKPD, learning videos, PBL, and PjBL-based assessments, as well as increase teachers' understanding in compiling and planning to learn so that it is more effective and has an impact on student's abilities. Service activities are carried out in 2 stages of lesson study, including Stage 1 Plan, held on Tuesday, August 2023, at SMAN 2 Kasongan. Stages 2 and 3 were implemented on Thursday, September 2023, by teacher readiness and implementation location at SMKN 1 Katingan Hilir. After implementation, all teachers provide reflections and share experiences to improve the learning that has been implemented. The PkM results have been uploaded on the YouTube channel of the UPR Mathematics Education Study Program.

Abstract

Mata pelajaran Bahasa Indonesia menuntut penguasaan keterampilan menyimak, berbicara, membaca, dan menulis, di mana kemampuan menulis kalimat menjadi dasar penting untuk mengembangkan paragraf. Penelitian ini bertujuan mendeskripsikan efektivitas penggunaan media kartu kata terhadap kemampuan menulis kalimat siswa kelas III SDN 1 Menteng Kota Palangka Raya. Metode penelitian yang digunakan adalah kuasi eksperimen dengan desain pretest and posttest control group design, melibatkan kelas III A sebagai kelas eksperimen dan kelas III B sebagai kelas kontrol. Data dikumpulkan melalui tes unjuk kerja dan dianalisis menggunakan uji deskriptif serta uji inferensial (uji normalitas, homogenitas, dan T-Welch). Hasil analisis deskriptif menunjukkan bahwa rata-rata skor kemampuan menulis kalimat siswa pada kelas eksperimen meningkat dari 65,80 pada pretest menjadi 77,40 pada posttest, sedangkan pada kelas kontrol meningkat dari 64,75 pada pretest menjadi 72,10 pada posttest. Hasil uji hipotesis dengan T-Welch menghasilkan nilai Sig. (2-tailed) sebesar 0,078 (> 0,05), sehingga hipotesis alternatif ditolak dan hipotesis nol diterima. Dengan demikian, penggunaan media kartu kata tidak memberikan efektivitas yang signifikan terhadap kemampuan menulis kalimat siswa, meskipun secara deskriptif terdapat peningkatan hasil belajar pada kedua kelas. Oleh karena itu, disarankan agar guru mengombinasikan kartu kata dengan media atau strategi pembelajaran lain yang lebih interaktif untuk meningkatkan keterampilan menulis kalimat siswa secara optimal.
