Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran kooperatif tipe GI  terhadap hasil belajar siswa pada materi pokok hukum newton di kelas X Semester I SMK Swasta Santo Paulus Martubung T.P 2018/2019. Jenis penelitian ini adalah quasi experiment dengan desain two group pretest-posttest. Populasi dalam penelitian ini adalah seluruh siswa kelas X dan sampel penelitian diambil dengan teknik random sampling terdiri dari dua kelas yaitu kelas eksperimen X TKR dan kelas kontrol X TKJ yang masing-masing berjumlah 36 orang siswa. Instrumen yang digunakan adalah tes tes hasil belajar yang telah divalidasi dalam bentuk pilihan berganda sebanyak 12 items dan lembar observasi aktivitas siswa yang dilakukan oleh dua observer. Hasil nilai pretest  diperoleh 41,69 dan posttest 74,8. Analisis uji t diperoleh thitung lebih besar daripada ttabel sehingga dapat disimpulkan ada perbedaan akibat pengaruh model pembelajaran kooperatif tipe GI  terhadap hasil belajar siswa pada materi pokok hukum newton di kelas X pembelajaran kooperatif tipe GI  terhadap hasil belajar siswa pada materi pokok hukum newton di kelas SMK Swasta Santo Paulus Martubung T.P 2018/2019.T.P 2018/2019.Kata Kunci : Kooperatif Tipe Group Investigation, Hasil Belajar, Hukum Newton

Abstract

This study addresses the issue of suboptimal student academic performance, which is frequently linked to the selection of instructional strategies that do not actively engage learners. Learning outcomes represent a multidimensional construct involving knowledge acquisition, attitude development, and skill formation. Therefore, the application of an appropriate learning model is essential to support meaningful learning experiences. This research aims to investigate the impact of implementing a Problem Based Learning (PBL) model supported by audio-visual media on students’ academic achievement. A quantitative approach with a quasi-experimental design was employed. The study involved two groups: an experimental class receiving the PBL intervention and a control class experiencing conventional instruction. Data were collected through pretest and posttest assessments and analyzed using both descriptive and inferential statistical techniques. The findings reveal a statistically significant difference between the two groups, indicated by a significance value below 0.05. This confirms that integrating problem-based strategies with audio-visual support contributes positively to improving students’ learning outcomes. The results highlight the importance of student-centered learning environments in fostering deeper understanding and engagement.

Abstract

This study aims to analyze the influence of financial literacy and financial behavior on students' investment interest. The background of this study is based on the low investment interest of students, indicated by the dominance of neutral to disagree responses on various investment interest indicators. The research method used is a quantitative approach with data collection techniques through questionnaires. The population in this study were students of the Economics Education Study Program at Nusa Cendana University, class of 2022-2025, with a sample of 209 respondents determined using a purposive sampling technique. Data analysis was performed using the classical assumption test, multiple linear regression, t-test, F-test, and coefficient of determination test. The results showed that financial literacy has a positive and significant effect on investment interest with a coefficient value of 0.539 and a significance of 0.000. Financial behavior also has a positive and significant effect on investment interest with a coefficient value of 0.335 and a significance of 0.000. Simultaneously, financial literacy and financial behavior have a significant effect on investment interest with a calculated F value of 159.661 and a significance of 0.000. Furthermore, the coefficient of determination test results showed an R-square value of 0.608, indicating that the two independent variables were able to explain 60.8% of the variation in investment interest, while the remainder was influenced by factors outside the study. Therefore, it can be concluded that improving financial literacy and financial behavior are important factors in increasing students' investment interest.Keywords: Financial Literacy, Financial Behavior, Consumer Behavior
