Abstract

This study aims to predict student achievement based on parental income and attendance. This study uses a quantitative approach with the population included all ninth grade students at SMP Swasta YP Utama Medan and the sample taken was 25 students. This study used instruments in the form of questionnaires and documentation. Data analysis used multiple linear regression to predict student academic achievement based on the variables of parental income and attendance. Prediction of students' achievement in grade IX at SMP Swasta YP Utama Medan based on parents' income and attendance patterns resulted in a Multiple Linear Regression equation that shows a positive relationship between economic conditions, students' attendance patterns and students' academic achievement. The accuracy level of prediction of student academic achievement based on parental income and attendance patterns shows that there are 16% of students getting excellent and 84% of students getting good grades

Abstract

This study focused on identifying the magnitude of the impact of a deep learning approach assisted by GeoGebra-based interactive PowerPoint media and animated videos on junior high school students’ conceptual understanding, particularly on the topic of straight-line equations. The research employed a quasi-experimental methodology with a pretest–posttest design involving two groups: the experimental group and the comparison group. The measurement instruments consisted of essay questions, and the data were analyzed using normality testing, homogeneity testing, and an independent t-test. The findings revealed a significant improvement in the experimental group’s conceptual understanding. The higher average posttest score compared to the control group confirmed that the use of interactive media enhanced students’ understanding of the material in a more visual and engaging way. Furthermore, the deep learning strategy optimized students’ active involvement in understanding and connecting relevant material to real-life situations. Thus, the synergy between digital media and this learning strategy was proven to effectively enhance conceptual understanding.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh penerapan media pembelajaran interaktif Desmos terhadap pemahaman siswa mengenai materi fungsi kuadrat. Penelitian dilakukan di SMP Swasta Utama Medan dengan menggunakan desain eksperimen One-Group Pre-test-Post-test. Sampel penelitian terdiri dari 27 siswa kelas IX yang mengikuti pembelajaran menggunakan media pembelajaran interaktif Desmos berbasis pendekatan Realistic Mathematics Education (RME) pada topik fungsi kuadrat. Intrumen penelitian terdiri atas soal-soal pre-test dan post-test yang telah dirancang untuk mengukur pemahaman siswa terhadap konsep fungsi kuadrat, khususnya mengenali jenis-jenis grafik fungsi kuadrat dan sifat koefisien fungsi kuadrat yang mempengaruhi perubahan bentuk grafik fungsi kuadrat. Hasil penelitian menunjukkan bahwa terdapat peningkatan nilai rata-rata dari 34,81 pada pre-test menjadi 70,37 pada post-test. Hasil uji-t menunjukkan bahwa terjadi peningkatan signifikan secara statistik () dan nilai probabilitas =  sehingga dapat disimpulkan bahwa penggunaan media pembelajaran interaktif Desmos memberikan pengaruh signifikan terhadap hasil belajar siswa pada materi fungsi kuadrat.
