Abstract

This study aims to investigate the effect of design-based STEM learning on students' scientific creativity in the context of solar energy. The study involved 64 tenth-grade students from a public Madrasah Aliyah in Jakarta, who were split into two groups: an experimental group that used design-based STEM learning and a control group that used conventional learning. Both groups were given a scientific creativity posttest in the form of seven open-ended questions. The study results showed that the experimental group's average scientific creativity score was higher than the control group's. Furthermore, the subdimensions analysis revealed that the experimental group's flexibility and originality significantly affected their scientific creativity. The study shows that design-based STEM learning positively impacts students' scientific creativity in the context of solar energy, although with a low category. This research can be a reference for future research to investigate the influence of design-based STEM learning on students' scientific creativity in various contexts.

Abstract

This study explores the effect of project-based learning (PBL) integrated with STEM on improving students' systemic thinking abilities. The study employed a quasi-experimental pretest-posttest control group design as its research method. The population consisted of 244 students enrolled in the tenth grade during the odd semester of the 2023-2024 academic year, and participants involved in the study were 68 tenth-grade students from one of the Islamic Senior High Schools of the State in Jakarta. The experimental group used PjBL STEM, while the control class used 5E learning (engagement, exploration, explanation, elaboration, and evaluation). The researcher developed a system thinking instrument adapted from Melinda based on pre-requirement, basic, intermediate, and coherent expert levels. In this study, data analysis used the non-parametric Mann-Whitney U test and Wilcoxon test. The research findings indicate a significant improvement in the system thinking ability of the experimental group students, while the control group's system thinking ability did not improve significantly. The results showed that the effect of PjBL STEM improvement in the experimental class was 0.54 (effect size) on students' systems thinking ability but was still in the low category and did not improve either in the control class. In addition, the level of systems thinking increased in the expert category, while the intermediate level did not increase. This study can be a reference for further research investigating the effect of PjBL STEM on students' systems thinking in different contexts.

Abstract

Kurangnya pengelolaan kondisi laboratorium dan keterbatasan alat praktikum menghambat pemahaman pada materi Fisika. Penelitian ini dilakukan untuk membuktikan cepat rambat bunyi di udara yang umumnya diketahui bernilai 340 m/s. Nilai cepat rambat bunyi diperoleh dari perhitungan setelah mendapat nilai frekuensi yang diukur menggunakan aplikasi pengukur frekuensi pada smartphone. Aplikasi yang digunakan yaitu Phyphox, Frequency Counter, dan Sound Level Meter yang akan dibandingkan hasilnya berdasarkan akurasi, presisi, dan tingkat ketelitian. Hasil penelitian menunjukkan cepat rambat di udara pada tiga aplikasi bernilai dari 325-337 m/s dengan besar kesalahan relatif terbesar yaitu 3,52%. Berdasarkan hasil analisis pada tingkat akurasi, presisi dan ketelitian aplikasi Frequency Counter menempati urutan paling baik. Jadi, peneliti merekomendasikan aplikasi Frequency Counter untuk digunakan sebagai pengganti alat ukur Sound Level Meter (SLM) di laboratorium.
