    Abstract

    Penelitian ini bertujuan untuk mengembangkan instrumen asesmen portofolio elektronik berbasis STEM pada materi pengaruh suhu terhadap laju reaksi untuk menilai keterampilan berpikir kritis peserta didik. Penelitian menggunakan model pengembangan 4D (Define, Design, Develop, Disseminate) yang dibatasi hingga tahap Develop. Subjek penelitian adalah peserta didik kelas XI SMA yang dipilih secara purposive. Instrumen penelitian yang digunakan terdiri dari lembar wawancara, lembar analisis capaian pembelajaran, lembar validasi, lembar reliabilitas, serta lembar penilaian task dan pretest-posttest. Uji validasi menggunakan Content Validity Ratio (CVR) menunjukkan bahwa instrumen berada pada kategori sangat valid dengan syarat perbaikan. Uji reliabilitas menggunakan Intraclass Correlation Coefficient (ICC) menunjukkan nilai berkisar dari kategori sedang hingga sangat baik. Hasil uji coba lapangan menunjukkan adanya peningkatan keterampilan berpikir kritis peserta didik setelah pemberian feedback, yang dibuktikan dengan uji Wilcoxon Signed Rank Test (p < 0,05) pada nilai setiap tugas. Peningkatan terjadi pada seluruh task, meskipun beberapa aspek masih memerlukan penyempurnaan rubrik penilaian. Penelitian ini menyimpulkan bahwa instrumen asesmen portofolio elektronik berbasis STEM layak digunakan untuk menilai keterampilan berpikir kritis peserta didik pada materi pengaruh suhu terhadap laju reaksi. This study aims to develop a STEM-based electronic portfolio assessment instrument on the material of the effect of temperature on reaction rates to assess students critical thinking skills. The study uses a 4D (Define, Design, Develop, Disseminate) development model limited to the Develop stage. The research subjects were grade XI high school students selected purposively. The research instruments used consisted of interview sheets, learning achievement analysis sheets, validation sheets, reliability sheets, task and pretest-posttest assessment sheets. The validation test using the Content Validity Ratio (CVR) showed that the instruments were highly valid with conditions for improvement. The reliability test using the Intraclass Correlation Coefficient (ICC) showed values ranging from moderate to very good. The field trial results showed an increase in students' critical thinking skills after feedback was given, as evidenced by the Wilcoxon Signed Rank Test (p < 0.05) on each task score. The improvement occurred in all tasks, although some aspects still required refinement of the assessment rubric. This study concludes that the STEM-based electronic portfolio assessment instrument is suitable for assessing students' critical thinking skills in the subject of the effect of temperature on reaction rates.
