Peningkatan Hasil Belajar Peserta Didik melalui Implementasi Pembelajaran Berbasis Assessment for Learning pada Materi Kesetimbangan Kimia

Improvement of Student Learning Outcomes through Implementation of Assessment for Learning on Chemical Equilibrium

Penelitian ini bertujuan untuk mendeskripsikan keterlaksanaan pembelajaran berbasis assessment for learning, aktivitas peserta didik pada saat kegiatan pembelajaran, peningkatan hasil belajar materi kesetimbangan kimia dan respon peserta didik terhadap kegiatan pembelajaran berbasis assessment for learning. Subyek dalam penelitian ini yaitu peserta didik kelas XI MIPA 4 di SMAN 3 Surabaya. Penelitian ini menggunakan jenis penelitian pra-eksperimen dengan menggunakan One Group Pretest-Posttest Design. Hasil dari penelitian menunjukkan bahwa (1) Kualitas keterlaksanaan pembelajaran berbasis assessment for learning mendapatkan kriteria sangat baik dalam tiga kali pertemuan dengan rata-rata persentase secara berturut-turut sebesar 91,08%, 95,16%, dan 95,76%; (2) Selama pembelajaran, aktivitas peserta didik yang relevan memiliki persentase lebih besar dibanding aktivitas peserta didik yang tidak relevan yaitu sebesar 93,47% pada pertemuan ke-I, 94,34% pada pertemuan ke-II, dan 94,44% pada pertemuan ke-III; (3) Hasil belajar peserta didik telah mencapai ketuntasan klasikal sebesar 90,91% dan telah mengalami peningkatan dengan persentase peserta didik yang memperoleh N-gain pada kriteria tinggi sebesar 87,88%, sedangkan persentase yang memperoleh N-gain pada kriteria sedang sebesar 12,12%; (4) Respon peserta didik setelah diterapkan pembelajaran berbasis assessment for learning mendapatkan persentase respon positif sebesar 90,12% dengan kriteria sangat baik.

The aim of this research was to describe the implementation of assessment for learning, student activities during learning activities, improving learning outcomes of chemical equilibrium material, and student responses to assessment for learning. The subjects of this study were students of class XI MIPA 4 at SMAN 3 Surabaya. This study uses a pre-experimental research design using One Group Pretest-Posttest Design. The results of this study show that (1) the quality of the implementation of assessment for learning got very good criteria in three meetings with an average percentage of 91.08%, 95.16%, and 95.76%, respectively; (2) During learning, the relevant student activities have a more significant percentage than the irrelevant student activities, which is 93.47% at the first meeting, 94.34% at the second meeting, and 94.44% at the second meeting; (3) The learning outcomes of students have achieved classical completeness of 90.91% and have increased with the percentage of students who obtained the N-gain on the high criteria of 87.88%, while the percentage who obtained the N-gain on the medium criteria is 12.12%; (4) The response of students after the assessment for learning was implemented got a positive response percentage of 90.12% with very good criteria.
