PEMBELAJARAN MODEL PROBLEM POSING PADA MATERI PEMANASAN GLOBAL UNTUK MENINGKATKAN KETERAMPILAN PROBLEM SOLVING SISWA

IMPLEMENTATION OF PROBLEM POSING MODELS ON GLOBAL WARMING CHAPTER TO IMPROVE STUDENT’S PROBLEM SOLVNG SKILLS

Penelitian ini bertujuan untuk mendeskripsikan keterlaksanaan pembelajaran, peningkatan keterampilan pemecahan masalah, dan respons siswa setelah diterapkan model Problem Posing. Penelitian ini merupakan penelitian Pre-Experimental Design dengan menggunakan rancangan percobaan One Group Pretest-Posttest Design. Instrument penelitan yang digunakan meliputi Lembar Observasi Aktivitas Guru, Lembar Tes Keterampilan Problem Solving Siswa dan Angket Respon Siswa yang dianalisis secara Deskriptif kuantitatif. Sampel yang digunakan dalam penelitian ini adalah siswa kelas VII-F SMPN 26 Surabaya. Hasil penelitian menunjukkan keterlaksanaan pembelajaran terkait aktivitas guru berlangsung sangat baik dengan skor rata-rata pertemuan I sebesar 3,4 dan pertemuan II sebesar 3,6. Keterampilan pemecahan masalah siswa meningkat dengan kriteria tinggi dengan rata-rata gain score sebesar 0,73. Peningkatan keterampilan Problem Solving terlihat dari hasil gain score ternormalisasi bahwa sebanyak 28 siswa pada kategori tinggi, 9 siswa dalam kategori sedang, sedangkan 1 siswa pada kategori rendah.  Siswa memberikan respon positif terhadap penerapan model Problem Posing pada materi pemanasan global dengan persentase sebesar 93,20% dengan kategori baik sekali. Hasil ini menyatakan bahwa penerapan model Problem Posing dapat meningkatkan keterampilan Problem Solving siswa pada materi pemanasan global.

This study aims to describe the implementation of learning, improvement of problem solving skills, and student responses after applying the Problem Posing model. This research is a Pre-Experimental Design study using the One Group Pretest-Posttest Design experimental design. The research instruments used included Teacher Activity Observation Sheet, Student Problem Solving Skills Test Sheet and Student Response Questionnaire which were analyzed descriptively quantitatively. The sample used in this study was grade VII-F students of SMPN 26 Surabaya. The results showed the implementation of learning related to teacher activities took place very well with an average score of meeting I of 3.4 and meeting II of 3.6. Students' problem solving skills increase with high criteria with an average gain score of 0.73. Increased Problem Solving skills can be seen from the normalized gain score results that as many as 28 students in the high category, 9 students in the medium category, while 1 student in the low category. Students gave a positive response to the application of the Problem Posing model in the matter of global warming with a percentage of 93.20% with excellent category. These results state that the application of the Problem Posing model can improve students' Problem Solving skills on global warming material.
