    Abstract

    Penelitian ini bertujuan mengembangkan instrumen asesmen portofolio elektronik berbasis STEM yang valid, reliabel, dan efektif untuk menilai keterampilan berpikir kritis peserta didik pada materi kesetimbangan kimia. Metode yang digunakan adalah Research and Development (R&D) dengan model 4D (Define, Design, Develop, Disseminate) yang dibatasi hingga tahap Develop. Subjek penelitian terdiri atas 25 peserta didik kelas XI di salah satu SMA di Kota Bandung. Instrumen yang dikembangkan berupa task dan rubrik penilaian, yang mencakup mind mapping, LKPD, dan teks esai. Hasil penelitian menunjukkan instrumen valid dengan nilai CVR 1,00 dan reliabel dengan Cronbach’s Alpha 0,771–1,000 (kategori baik hingga sangat baik). Uji Wilcoxon pada ketiga task menunjukkan signifikansi (p-value < 0,05), menandakan adanya perbedaan signifikan antara hasil sebelum dan sesudah feedback. His study aims to develop a STEM-based electronic portfolio assessment instrument that is valid, reliable, and effective for evaluating students’ critical thinking skills on the topic of chemical equilibrium. The research employed a Research and Development (R&D) approach using the 4D model (Define, Design, Develop, Disseminate), which was limit up to the Develop stage. The subjects of the study consisted of 25 eleventh-grade students from a senior high school in Bandung City. The developed instrument included tasks and assessment rubrics, covering mind mapping, student worksheets (LKPD), and essay texts. The results indicated that the instrument was valid with a CVR score of 1.00 and reliable with Cronbach’s Alpha values ranging from 0.771 to 1.000 (categorized as good to very good). The Wilcoxon test on the three tasks showed significance (p-value < 0.05), indicating a significant difference between the results before and after feedback.
