Abstract

This study investigates the key indicators of interest and motivation in mathematics learning using confirmatory factor analysis (CFA) to validate their relevance and reliability. Conducted in Bandar Lampung, Indonesia, the research involved 111 junior high school students selected through cluster random sampling. Two latent variables were examined: interest, represented by four indicators (feeling of happiness, student curiosity, student attention, and student involvement), and motivation, represented by five indicators (perseverance, tenacity, sharpness of attention, achievement, and independence). Results revealed that only student curiosity (KMO = 0.611) and student involvement (KMO = 0.507) were valid indicators of interest, while perseverance (KMO = 0.685), tenacity (KMO = 0.628), and sharpness of attention (KMO = 0.616) were valid indicators of motivation. The validated indicators highlight the intrinsic and participatory nature of engagement, emphasizing the importance of fostering curiosity, involvement, and resilience in mathematics learning. The findings contribute to the theoretical integration of interest and motivation as interconnected constructs and offer practical implications for designing targeted instructional strategies. This study provides a robust framework for understanding student engagement in mathematics and serves as a foundation for future research on contextual and longitudinal dynamics of these constructs.

Abstract

The Covid-19 pandemic has significantly impacted adolescents, particularly within the learning environment. Despite the low prevalence of COVID-19 among adolescents and the general mild symptoms or asymptomatic nature of their cases, the pandemic has induced significant psychological changes and social challenges. Therefore, this study focused on quality of life and mental health of students at Indonesian religious colleges during the COVID-19 pandemic, where religious aspects are integral to the curriculum. It adopted a cross-sectional design with an initial analysis using SPSS version 29. The sample included 395 students from various educational programmes, comprising 14% males and 86% females, with an average age of 19.65 years (SD = 1.03). The results showed that mental health was a crucial factor affecting students quality of life, particularly within the Preschool Education programme. Gender disparities were observed in areas such as physical health and depression, necessitating customised support in educational settings. Variations in students' perceived health status were also identified in specific programmes, such as mathematics and guidance education, showing the impact of academic environments. Generally, the study showed the crucial need for targeted interventions to address mental health issues and support students' quality of life during and after the pandemic.

Abstract

Geometri sebagai salah satu bidang kajian dalam materi matematika sekolah memperoleh porsi yang besar untuk dipelajari oleh siswa di sekolah. Dari distribusi penyebaran standar kompetensi untuk satuan pendidikan SMP, materi geometri mendapatkan porsi yang paling besar (41%) dibandingkan dengan materi lain seperti aljabar (29%), bilangan (18%), serta statistika dan peluang (12%). Namun demikian, penguasaan siswa dalam memahami konsep geometri masih rendah dan perlu ditingkatkan.Pengajaran geometri di sekolah diharapkan memberikan suatu sikap dan kebiasaan sistematik bagi siswa untuk bisa memberikan gambaran tentang hubungan-hubungan di antara bangun-bangun geometri serta penggolongan-penggolongan di antara bangun-bangun tersebut, untuk itu agar dalam pembelajaran geometri siswa dapat memvisualisasikan, menggambarkan, serta memperbandingkan bangun-bangun geometri dalam berbagai posisi, sehingga siswa dapat memahaminya dibutuhkan sebuah model pembelajaran berbasis software komputer dynamic geometry software yaitu GeoGebra. Dengan bantuan software ini siswa lebih memahami konsep-konsep dalam geometri. Pertimbangan tentang penggunaan dynamic geometry software seperti GeoGebra dalam pembelajaran matematika, khususnya geometri, diantaranya memungkinkan siswa untuk aktif dalam membangun pemahaman geometri.Pembelajaran geometri berbasis GeoGebra pada proses pembelajaran terbukti secara signifikan dapat meningkatkan kemampuan komunikasi matematis siswa, selaian itu sikap kritis dan kreatif selama pembelajaran ditunjukkan siswa. Peningkatan kemampuan komunikasi matematis siswa yang mendapat pembelajaran geometri berbasis GeoGebra berada pada kategori sedang. Hal ini menunjukkan bahwa siswa telah mengalami peningkatan kemampuan komunikasi matematis lebih baik dibandingkan hasil sebelumnya.

Abstract

Pembelajaran dengan menggunakan buku ajar elektroniksemestinya memiliki nilai lebih dibandingkan dengan buku cetak biasa yang banyak beredar. Nilai lebih tersebut ada karena pemakaian BAE harus menggunakan alat bantu berupa komputer (PC), e-book reader, tablet,  maupun smartphone untuk membukanya. Dengan alat bantu yang digunakan, sepatutnya BAE mampu menampilkan simulasi-simulasi yang interaktif dengan ditambahkan fitur-fitur berupa video, animasi, suara maupun gambar. Buku ajar seperti ini dikenal dengan istilah Buku Ajar Elektronik Interaktif (BAEI). Madrasah dan Perguruan Tinggi Islam dewasa ini mulai mengembangkan pengintegrasian ilmu-ilmu sains ke dalam nilai-nilai keislaman. Pengintegrasian nilai-nilai keislaman dalam buku ajar matematika setidaknya dapat tergambar dalam contoh soal, soal latihan dan soal ujian yang mengangkat masalah-masalah yang terjadi dalam perpekstif islam tanpa mengubah standar kompetensi yang terkandung dalam kurikulum yang telah ditetapkan.Visualisasi yang ditampilkan dalam BAEI yang dapat digerakkan dan diubah bentuk serta ukurannya, memberi kesempatan kepada siswa untuk melakukan eksplorasi dan observasi dengan mudah sehingga kemampuan koneksi matematis dapat meningkat. Hal ini terbukti dari hasil penelitian yang telah dilakukan.Penelitian ini merupakan penelitiankuasi eksperimen berdisain pretes-postes dengan tujuan menjawab permasalahan apakah terdapat peningkatan kemampuan koneksi matematis siswa dengan menggunakan bahan ajar elektronik interaktif yang terintegrasi nilai-nilai keislaman. Subyek penelitian sebanyak 32siswa kelas XI, instrumen yang digunakan dalam penelitian ini berbentuk tes dan terdiri dari dua perangkat tes untuk kemampuan koneksi matematis. Hipotesis statistik dalam penelitian ini diuji menggunakan uji t dengan taraf signifikansi 5%. Hasil uji statistik menunjukkan bahwa terdapat peningkatan kemampuan koneksi matematis siswa dengan menggunakan bahan ajar elektronik interaktif yang terintegrasi nilai-nilai keislaman.
