Abstract

This study aims to investigate the effect of lecture timing on learning outcomes in Multivariable Calculus using One-Way ANOVA. The type of research is quantitative. The subjects of this study are students of the Mathematics Education program at Jember University from class of 2023, for the Academic Year 2024-2025, enrolled in the regular Multivariable Calculus course. The samples were purposively selected: Class A (morning class) with 35 students, Class B (afternoon class) with 37 students, and Class E (evening class) with 30 students. The sample data were free of outliers, normally distributed, and homogeneous. The results show that and p-value < 0.05, indicating that at a 95% confidence level, there is at least one pair of treatments with significantly different average learning outcomes. Based on the Post Hoc test, significant differences in average learning outcomes were found between Class A and Class B, and between Class A and Class E, while betweet Class B and Class E did not show significant differences in average learning outcomes. Keywords: learning outcomes, lecture timing, One-Way ANOVA

Abstract

Education in Indonesia faced significant challenges during the COVID-19 pandemic, particularly with the transition from face-to-face to online learning. Many obstacles occur in this online learning system which may affect student achievement. This research aims to analyze the effect of the COVID-19 pandemic on student achievement which is reviewed statistically descriptively and inferentially. This research was conducted at SMK Ma'arif 9 Kebumen with a sample of one class X. The research method used was using a quantitative approach, namely the Wilcoxon Signed Rank Test. The analysis results show that based on a 95% confidence level, there is a significant difference between the average learning achievement of students before the pandemic and after the COVID-19 pandemic occurred, with a decrease in the average student scores of 2.98% from the average student scores before the COVID-19 pandemic. Keywords: Wilcoxon Signed Rank Test, COVID-19's Impact, Learning Achievement

Abstract

Artikel ini bertujuan untuk mendeskripsikan kemampuan penalaran matematis mahasiswa yang tergambar melalui hasil mini riset pada mata kuliah Logika Fuzzy. Penelitian ini menggunakan metode deskriptif kualitatif untuk mendeskripsikan kemampuan penalaran matematis mahasiswa dalam konteks Logika Fuzzy, yang tergambar melalui hasil mini riset pada mata kuliah Logika Fuzzy. Hasil penelitian menunjukkan bahwa sebagian besar mahasiswa mampu mengjukan dugaan, manipulasi matematika, menyusun bukti, dan menarik kesimpulan yang relevan. Namun, beberapa laporan mini riset mahasiswa menunjukkan kesulitan dalam memverifikasi argumen dan menarik kesimpulan yang lebih akurat. Dari penelitian ini dapat disimpulkan bahwa mahasiswa menunjukkan kemampuan penalaran matematis yang baik dalam konteks Logika Fuzzy, meskipun beberapa aspek masih perlu ditingkatkan.

Abstract

The book writing training with an International Standard Book Number (ISBN) for teachers at SMA Negeri Plus Sukowono was carried out as an effort to improve literacy and writing productivity among educators. Teachers’ enthusiasm for writing was quite high, but most still faced difficulties in preparing systematic manuscripts and understanding the procedures for publishing ISBN books. This community service activity was implemented using a participatory approach through three main stages, namely needs identification, material delivery, and writing assistance. The training materials covered finding book ideas, understanding structures and types of books, and avoiding plagiarism in writing. The activity was conducted in the form of interactive lectures, hands-on drafting practice, and question-and-answer sessions. The final results showed a significant increase in participants’ understanding of the training materials. Some participants successfully compiled outlines and began writing their own book manuscripts. This activity served as an initial step in establishing a school literacy culture centered on teachers’ work, while also opening up opportunities for higher-quality publications in the future. ABSTRAK Kegiatan pelatihan penulisan buku dengan International Standard Book Number (ISBN) bagi guru SMA Negeri Plus Sukowono dilaksanakan sebagai upaya untuk meningkatkan literasi dan produktivitas karya tulis di kalangan pendidik. Antusiasme guru dalam menulis cukup tinggi, tetapi sebagian besar masih menghadapi kendala dalam menyusun naskah yang sistematis dan memahami prosedur penerbitan buku ber-ISBN. Pengabdian ini dilaksanakan dengan pendekatan partisipatif melalui tiga tahapan utama, yaitu identifikasi kebutuhan, penyampaian materi, dan pendampingan penulisan. Materi pelatihan mencakup menemukan ide penulisan buku, sistematika dan jenis-jenis buku, serta menghindari plagiarisme dalam penulisan buku. Kegiatan ini berlangsung dalam bentuk ceramah interaktif, praktik langsung penyusunan draf buku, serta sesi tanya jawab. Hasil akhir menunjukkan peningkatan signifikan dalam pemahaman peserta terhadap materi pelatihan. Sebagian peserta berhasil menyusun kerangka dan mulai menulis naskah buku masing-masing. Kegiatan ini menjadi langkah awal dalam membangun budaya literasi sekolah berbasis karya guru, sekaligus membuka peluang bagi lahirnya publikasi yang lebih berkualitas di masa mendatang.
