Abstract

Penelitian ini bertujuan untuk mengembangkan asesmen portofolio elektronik berbasis STEM (Science, Technology, Engineering, Mathematics) untuk menilai habits of mind pada topik faktor-faktor yang mempengaruhi laju reaksi yang valid dan reliabel. Dengan metode Research and Development-4D dengan tahapan yang dilaksanakan yakni 3 tahap (define, design, dan develop). Penelitian ini melibatkan 27 peserta didik kelas XI di salah satu SMA di Kota Bandung. Task yang dikembangkan terdiri dari, laporan praktikum, soal esai, dan poster. Instrumen divalidasi berdasarkan pertimbangan para judgment yang terdiri dari tiga dosen Pendidikan kimia dan dua pendidik mata pelajaran kimia sebagai validator. Uji reliabilitas dilakukan dengan metode inter-rater menggunakan 5 orang rater. Hasil menunjukkan bahwa instrumen tersebut valid dengan nilai CVR 1 dan reliabel dengan hasil Intraclass correlation coefficient (ICC) 0,774-0,948. Secara keseluruhan, didapat rata-rata skor N-Gain adalah 0,753 yang menunjukkan kategori tinggi. Berdasarkan uji coba terbatas terhadap asesmen penilaian portofolio elektronik berbasis STEM, menunjukkan bahwa asesmen yang dikembangkan berupa task dan rubrik dapat menilai habits of mind peserta didik pada topik faktor-faktor yang mempengaruhi laju reaksi. This study aims to develop a STEM-based electronic portfolio assessment (Science, Technology, Engineering, Mathematics) to assess habits of mind on the topic of factors affecting reaction rates that are valid and reliable. With the Research and Development-4D method with the stages carried out, namely 3 stages (define, design, and develop). This study involved 27 students of class XI in one of the high schools in Bandung City. The tasks developed consisted of practicum reports, essay questions, and posters. The instrument was validated based on the judgment of three chemistry education lecturers and two chemistry educators as validators. Reliability test was conducted with inter-rater method using 5 raters. The results showed that the instrument was valid with a CVR value of 1 and reliable with Intraclass correlation coefficient (ICC) results of 0.774-0.948. Overall, the average N-Gain score was 0.753 which showed a high category. Based on the limited trial of the STEM-based electronic portfolio assessment, it shows that the assessment developed in the form of tasks and rubrics can assess students' habits of mind on the topic of factors that affect the reaction rate.
