Abstract

This research aims to increase learning activities and learning outcomes through the application of problem solving methods guided to the basic laws of chemistry class X Mia. This study was conducted in class X sma Negeri 1 Tompaso with a sample number of 20 people. This study is a Class Action Research consisting of 2 cycles. Each cycle includes 4 stages, namely planning, implementation, documentation observation, tests and questionnaires. Data analysis uses descriptive methods. The results showed that the application of guided problem solving methods can increase learning activity (from 64% in cycle 1 to 85% in cycle II) as well as affective aspects (from 68.16% to 75.44%) in the basic laws of chemistry class X Mia Sma Negeri 1 Tompaso school year 2018/2019.

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui rata-rata hasil belajar siswa dengan menerapkan media video pembelajaran pada materi asam basa di kelas XI MIPA SMA Negeri 1 Langowan. Penelitian ini adalah penelitian kuantitatif menggunakan metode eksperimen dengan menggunakan desain posttest only control group design. Sampel dalam penelitian ini adalah kelas XI MIPA 2 sebagai kelas eksperimen dan XI MIPA 3 sebagai kelas kontrol dengan masing-masing kelas berjumlah 30 siswa. Pengambilan data dilakukan dengan memberikan posttest setelah proses pembelajaran. Data hasil penelitian yang diperoleh berupa selisih nilai rata-rata posttest kelas eksperimen dan kelas kontrol yaitu sebesar 36,2. Dengan rata-rata nilai posttest kelas eksperimen yaitu 83,37 sedangkan rata-rata nilai posttest kelas kontrol yaitu 47,17. Uji hipotesis pada penelitian ini menggunakan uji t pada . Hasil analisis data untuk hasil belajar diperoleh yaitu thitung = 12,201 ttabel = 2,001. Dengan demikian dapat disimpulkan bahwa rata-rata hasil belajar siswa dengan menggunakan media video pembelajaran lebih tinggi dari pada rata-rata hasil belajar siswa dengan menggunakan metode ceramah pada materi asam basa di SMA Negeri 1 Langowan.

Abstract

The purpose of this study was to determine the Effectiveness of the Implementation of the ICARE Learning Model on Student Chemistry Learning Outcomes in Acid-Base Material. This research was conducted in class XI MIA SMA Budi Luhur Kembang Mertha in the 2022/2023 academic year. A total of 24 students of class XI MIA were selected as the research sample. This research is a quantitative study using an experimental method with a one-group pretest-posttest design. The data collection technique uses a learning achievement test which is given a pretest before the learning process is carried out and a posttest after the learning process is carried out. From these results it can be concluded that the implementation of the ICARE learning model can effectively improve students' chemistry learning outcomes in the subject matter of class XI acids and bases at SMA Budi Luhur Kembang Mertha.
