Penguasaan Konsep dengan Pembelajaran STEM Berbasis Masalah Materi Fluida Dinamis pada Siswa SMA
Abstract
Abstract: Concept mastery is the ability to understand concepts theoretically and apply the concept to solve a problem. Dynamic fluid is a material that is difficult for students to understand because of the complexity of the underlying physical concepts that lead to concept mastery of student dynamic fluid low. This study aims to determine the effect of STEM-based learning problems on mastery of student concepts in dynamic fluid materials. This research method is Mixed Methods Embedded Experimental Design. The subjects consisted of 27 students of SMA Negeri 3 Batu. Data were collected through pretest and posttest using tests, questionnaires and interviews. Quantitative data analysis using Wilcoxon Signed Rank Test, Normalized Gain Score, and Effect Size. Qualitative data analysis using Coding, Data Reduction, Data Display, and Conclusion Drawing/ Verification. Wilcoxon Signed Rank Test results obtained by Asymp.Sig. (2-tailed) value of 0.000 <0.005. Normalized Gain Score calculation results obtained value of 0.58 (medium). Effect Size calculation results are worth 1.44 (strong). The results showed that there is an effect of STEM-based learning problems on mastery of student concepts in dynamic fluid materials.
Abstrak: Penguasaan konsep merupakan kemampuan untuk memahami konsep secara teoritis dan menerapkan konsep tersebut untuk memecahkan suatu permasalahan. Fluida dinamis adalah materi yang sulit dipahami siswa karena kompleksitas konsep fisika yang mendasarinya sehingga menyebabkan penguasaan konsep fluida dinamis siswa rendah. Penelitian ini bertujuan untuk mengetahui pengaruh pembelajaran STEM berbasis masalah terhadap penguasaan konsep siswa dalam materi fluida dinamis. Metode penelitian ini adalah Mixed Methods Embedded Experimental Design. Subjek penelitian terdiri atas 27 siswa SMA Negeri 3 Batu. Data dikumpulkan melalui pretest dan posttest menggunakan tes, kuesioner, dan wawancara. Analisis data secara kuantitatif menggunakan Wilcoxon Signed Rank Test, Normalized Gain Score, dan Effect Size. Analisis data secara kualitatif menggunakan Coding, Data Reduction, Data Display, dan Conclusion Drawing/Verification. Hasil perhitungan Wilcoxon Signed Rank Test diperoleh nilai Asymp.Sig.(2-tailed) sebesar 0,000 < 0,005. Hasil perhitungan Normalized Gain Score diperoleh nilai 0,58 (sedang). Hasil perhitungan Effect Size bernilai 1,44 (kuat). Hasil penelitian menunjukkan bahwa terdapat pengaruh pembelajaran STEM berbasis masalah terhadap penguasaan konsep siswa dalam materi fluida dinamis.
