Penelitian ini dilatarbelakangi oleh rendahnya tingkat kreativitas siswa dalam proses pembelajaran IPAS di kelas V SD Negeri 1 Bojong. Tujuan utama dari penelitian ini adalah: (1) untuk menganalisis perbedaan tingkat kreativitas antara siswa yang mengikuti pembelajaran dengan model Project Based Learning dan siswa yang memperoleh pembelajaran melalui model ekspositori, serta (2) untuk mengetahui peningkatan kreativitas siswa setelah penerapan model Project Based Learning di kelas eksperimen. Penelitian ini menggunakan pendekatan kuantitatif dengan desain quasi eksperimen. Model Project Based Learning bertindak sebagai variabel bebas, sementara kreativitas siswa merupakan variabel terikat. Subjek penelitian terdiri atas 55 siswa kelas V SD Negeri 1 Bojong tahun ajaran 2024/2025, yang terbagi dalam dua kelompok: 29 siswa pada kelas eksperimen dan 26 siswa pada kelas kontrol. Data dikumpulkan melalui angket dan lembar penilaian produk, kemudian dianalisis dengan menggunakan uji-t, serta uji N-Gain. Hasil penelitian menunjukan terdapat perbedaan yang dibuktikan dengan hasil uji t, selain itu diketahui ada peningkatan yang dibuktikan N-Gain yang signifikan antara kemampuan kreativitas siswa yang menggunakan model pembelajaran Project Based Learning dan siswa yang menggunakan model pembelajaran ekspositori. Selanjutnya, hasil uji N-Gain menunjukkan bahwa kelas eksperimen memperoleh nilai 0,74 (kategori tinggi), sedangkan kelas kontrol memperoleh nilai 0,37 (kategori rendah). Dengan demikian, model pembelajaran Project Based Learning terbukti memiliki pengaruh dalam meningkatkan kemampuan kreativitas siwa kelas V SDN 1 Bojong dibandingkan dengan model pembelajaran ekspositori.

This study is motivated by the low level of student creativity in the IPAS learning process among fifth-grade students at SD Negeri 1 Bojong. The main objectives of this research are: (1) to analyze the differences in creativity levels between students who participate in learning through the Project Based Learning (PjBL) model and those who receive learning through the expository model, and (2) to determine the improvement in student creativity following the implementation of the Project Based Learning model in the experimental class. This research employs a quantitative approach with a quasi-experimental design. The Project Based Learning model serves as the independent variable, while student creativity is the dependent variable. The research subjects consisted of 55 fifth-grade students at SD Negeri 1 Bojong in the 2024/2025 academic year, divided into two groups: 29 students in the experimental class and 26 students in the control class. Data were collected through questionnaires and product assessment sheets, and analyzed using the t-test and N-Gain test. The results of the study show a significant difference, as evidenced by the t-test results. In addition, a significant improvement was found through the N-Gain test between the creativity levels of students who used the Project Based Learning model and those who used the expository learning model. Furthermore, the N-Gain test results indicate that the experimental class achieved a score of 0.74 (high category), while the control class scored 0.37 (low category). Thus, the Project Based Learning model has been proven to have an impact on improving the creativity skills of fifth-grade students at SDN 1 Bojong compared to the expository learning model.
