PENERAPAN MODEL PEMBELAJARAN BERBASIS MASALAH UNTUK MENINGKATKAN HASIL BELAJAR KIMIA

Abstract

The aimed of this study was to improve the quality of learning by analyzing and finding out accurately: (1) chemistry learning plan design focusing on redoks materials using problem based learning model, (2) process of chemistry learning, (3) assessment instruments at the end of the learning activity, and (4) improvement of learning outcomes in chemistry.This study was an action research with 3 cycle. Data were collected using observation and tests, and the quantitative descriptive analysis. The research result were : (1) the learning plan was made by initially determining student needs , followed by constructing learning objectives that measure the ability to solve the problems, (2) during learning, students observed activity is observed honestly, cooperation, discipline and curiosity (3) assessment instrument using a written test which the description of the instrument has been tested and the results are valid 0,77 and reliable 0,76 average difficulty level of items, and the distinguish power of items is well.

Penelitian bertujuan memperbaiki kualitas pembelajaran dengan menganalisis dan menemukan: (1) rencana pembelajaran kimia materi redoks dengan model PBM (2) proses pembelajaran kimia yang tepat, (3) instrumen assessment di akhir pembelajaran, (4) peningkatan hasil belajar kimia.Penelitian ini merupakan penelitian tindakan dengan tiga siklus. Data dikumpulkan dengan observasi dan tes, dan dianalisis deskriptif kuantitatif. Hasil penelitian (1) pembuatan rencana pembelajaran diawali dengan kebutuhan belajar peserta didik yang belum memahami materi redoks, selanjutnya menyusun tujuan pembelajaran untuk mengukur kemampuan pemecahan masalah pada materi redoks, (2) selama pembelajaran, aktifitas peserta didik yang diamati adalah kejujuran, kerjasama, disiplin dan keingintahuan, (3) instrumen assessment menggunakan tes tertulis uraian dengan validitas 0,77, reliabilitas 0,76, tingkat kesukaran sedang, dan daya pembeda soal baik.

Kata kunci: hasil belajar, kimia, model PBM
