Improving Students' Problem Solving Skills in Learning Problem Based Learning Integrated with Predict, Observe, Explain Model on Global Warming Material

In the following study, the aim is to analyze the improvement of students' problem solving skills in learning activities with problem-based learning models integrated with predict, observe, explain models, especially for global warming material. The study was conducted using quantitative methods with 33 participants of class X students at one of the SMAN Cimahi City which was determined based on convenience sampling technique. The data collected in the following study was conducted through a problem solving skills test instrument in the form of pretest and posttest questions. To analyze the data obtained, using N-Gain testing on the data from the pretest and posttest scores. The results showed that each aspect of problem solving skills experienced a moderate increase. In addition, the acquisition of hypothesis testing proves that there is a difference in the application of the PBL-POE model in improving students' problem solving skills.
