IMPLEMENTASI PEMBELAJARAN BERBASIS ASSESSMENT FOR LEARNING UNTUK MENINGKATKAN HASIL BELAJAR PESERTA DIDIK MATERI IKATAN KIMIA 

IMPLEMENTATION OF ASSESSMENT FOR LEARNING TO IMPROVE STUDENT'S COGNITIVE LEARNING OUTCOMES IN CHEMICAL BONDING MATERIALS

Tujuan dari penelitian ini ialah untuk mendeskripsikan keterlaksanaan pembelajaran berbasis Assessment for Learning, aktivitas peserta didik, peningkatan hasil belajar kognitif dan respon peserta didik setelah diterapkan pembelajaran berbasis Assessment for Learning. Jenis penelitian ini yaitu pra-eksperimen dengan desain penelitian one group pretest posttest design. Subyek penelitian kelas X sebanyak 39 peserta didik. Hasil penelitian yang dilakukan menunjukkan bahwa keterlaksanaan pembelajaran berbasis Assessment for Learning selama pertemuan pertama, kedua dan ketiga dinyatakan terlaksana dengan sangat baik dengan persentase sebesar 93.6%, 94.9% dan 98.6%. Peserta didik beraktivitas baik selama tiga kali pertemuan sesuai dengan prinsip-prinsip dalam Assessmen for Learning dengan persentase sebanyak 94.9%, 92.9%, 97.0%. Peningkatan hasil belajar peserta didik setelah diterapkannya pembelajaran berbasis Assessment for Learning diperoleh sebanyak 92.3% peserta didik dalam kategori n-gain tinggi dan 7.7% peserta didik dalam kategori n-gain sedang serta diperoleh ketuntasan hasil belajar secara klasikal sebesar 94.8%. Respon peserta didik terhadap pembelajaran berbasis Assessment for Learning mendapatkan respon baik dengan persentase sebesar 89%. Kesimpulannya pembelajaran berbasis Assessment for Learning dapat meningkatkan hasil belajar peserta didik kelas X pada materi ikatan kimia.

The purpose of this study is to describe the implementation of Assessment for Learning-based learning, student activities, improving cognitive learning outcomes, and student responses after applying Assessment for Learning-based education. This type of research is a pre-experimental research design with one group pretest-posttest design. The research subjects for class X were 39 students. The study results showed that the implementation of Assessment for Learning-based learning during the first, second and third meetings was stated to be very well carried out with the percentages of 93.6%, 94.9%, and 98.6%. The students did suitable activities for three meetings by the principles in the Assessment for Learning with 94.9%, 92.9%, 97.0%. After the implementation of Assessment for Learning-based learning, the increase in student learning outcomes was obtained as many as 92.3% of students in the high n-gain category and 7.7% of students in the medium n-gain category and obtained classical learning completeness of 94.8%. Student responses to Assessment for Learning-based learning get a good response with a percentage of 89%. In conclusion, Assessment for Learning-based learning can improve the learning outcomes of class X students on the chemical bonding material
