Abstract

This study aims to analyze the effectiveness of integrating Project-Based Learning (PjBL) with Science, Technology, Engineering, and Mathematics (STEM) and virtual laboratories in enhancing 21st-century scientific literacy among junior high school students. A quasi-experimental design employing a one-group pretest–posttest model was used, involving 25 seventh-grade students from SMP Negeri 11 Yogyakarta. Data were collected using a scientific literacy test encompassing three dimensions: explaining phenomena scientifically, interpreting data and scientific evidence, and evaluating and using scientific information. The results revealed a significant difference between pretest and posttest scores (p < 0.05), with a normalized gain score of 0.62 categorized as medium. The greatest improvement occurred in the dimension of explaining phenomena scientifically (0.83), followed by interpreting data and scientific evidence (0.67), and evaluating and using scientific information (0.58). The integration of PjBL-STEM with virtual laboratories enhanced students’ conceptual understanding, scientific reasoning, and inquiry skills through interactive and contextual learning experiences. These findings demonstrate that the hybrid PjBL-STEM model, supported by virtual laboratory simulations, effectively promotes 21st-century scientific literacy. Moreover, this study provides empirical evidence on how the integration of PjBL-STEM and virtual laboratories can bridge the gap in scientific literacy development within Indonesian secondary education.

Abstract

Instrumen penilaian yang berkualitas diperlukan untuk mengukur hasil belajar peserta didik secara akurat dan dapat dipertanggungjawabkan. Penelitian ini bertujuan menguji secara empiris kualitas achievement test pada materi sistem peredaran darah dalam pembelajaran IPA terintegrasi Augmented Reality. Uji empiris dilakukan pada satu kelas dengan jumlah peserta didik sesuai kondisi lapangan. Sebanyak 50 butir soal dianalisis menggunakan SPSS untuk mengetahui validitas, reliabilitas, tingkat kesukaran, dan daya pembeda. Hasil analisis menunjukkan bahwa sebagian besar butir soal memiliki nilai korelasi di atas r-tabel dan reliabilitas KR-20 berada pada kategori tinggi. Mayoritas butir juga berada pada tingkat kesukaran sedang serta memiliki daya pembeda yang baik. Dengan demikian, achievement test yang dikembangkan dinyatakan layak digunakan sebagai instrumen evaluasi pembelajaran IPA. Instrumen ini diharapkan dapat mendukung evaluasi pembelajaran berbasis teknologi serta menjadi acuan dalam penelitian lanjutan terkait pembelajaran IPA terintegrasi AR.
