PENGEMBANGAN INSTRUMEN TES BERPIKIR KRITIS

BERORIENTASI PRODUK PJBL-STEAM TERINTEGERASI

EDUCATION FOR SUSTAINABLE DEVELOPMENT (ESD) PADA PEMBELAJARAN FISIKA

DEVELOPMENT OF CRITICAL THINKING INSTRUMENT

TEST PRODUCT-ORIENTED PJBL-STEAM AND

INTEGRATED EDUCATION FOR SUSTAINABLE DEVELOPMENT (ESD) IN PHYSICS LEARNING

Penelitian ini bertujuan untuk menganalisis kualitas meliputi validitas, reliabilitas, dan tingkat kesukaran instrumen tes berpikir kritis berorientasi produk PjBL-STEAM terintegerasi ESD pada materi energi terbarukan dan tak terbarukan, menganalisis profil keterampilan berpikir kritis peserta didik, serta mendeskripsikan respon peserta didik dan guru terhadap instrumen tes yang dikembangkan. Penelitian ini merupakan jenis penelitian RnD dengan memodifikasi model pengembangan Formative Evaluations Teesmer. Subyek utama penelitian yaitu 28 peserta didik putra kelas X Science 1 SMA Trensains Tebuireng Jombang yang telah menyelesaikan pembelajaran PjBL-STEAM pada materi yang sama sebelumnya. Teknik pengumpulan data menggunakan instrumen tes esai sebanyak 3 item (terdiri dari poin A hingga F) dan angket. Teknik analisis data berdasarkan analisis Rasch Model dengan bantuan software Ministep. Hasil penelitian telah menunjukkan bahwa: 1) instrumen tes yang dikembangkan dinyatakan valid, reliabel, dan tingkat kesukaran ix item terdistribusi merata 2) rata-rata profil keterampilan berpikir kritis peserta didik berada pada kategori sedang, 3) rata-rata respon peserta didik dan guru berada pada kategori sangat positif. Berdasarkan hasil penelitian di atas, dapat disimpulkan bahwa rangkaian pembelajaran PjBL-STEAM terintegerasi ESD beserta penilaian sumatif individu menggunakan instrumen tes berpikir kritis yang dikembangkan pada penelitian ini dapat digunakan sebagai alternatif guru untuk menerapkan sistem pembelajaran pada materi fisika lainnya.

This study aims to analyze the quality including the validity, reliability, and level of difficulty of the critical thinking instrument test product-oriented PjBL-STEAM and integrated ESD on renewable and non-renewable energy materials, analyze the profile of students' critical thinking skills, and describe the responses of students and teachers to the instrument. This research is a type of RnD research by modifying Teesmer's Formative Evaluations development model. The main subjects of the study were 28 male students in class X Science 1 at Trensains Tebuireng Jombang High School who had completed PjBLSTEAM learning on the same material before. The data collection technique used an essay test instrument consisting of 3 items (consisting of points A to F) and a questionnaire. The data analysis technique is based on the Rasch Model analysis using Ministep software. The results of the study have shown that: 1) the developed test instruments are declared valid, reliable, and the item difficulty levels are evenly distributed 2) the average profile of students' critical thinking skills is in the medium xi category, 3) the average responses of students and teachers are in the very positive category. Based on the results of the research above, it can be concluded that the ESD-integrated PjBL-STEAM learning series along with individual summative assessments using the critical thinking test instrument developed in this study can be used as an alternative for teachers to apply learning systems to other physics materials.
