Improving Science Processes Skills and Learning Outcomes of Junior High School Students on Problem Based Learning

This study aims to improve the science process skills and student-learning outcomes with problem based learning management. This study used embedded experiments. The population of this study was Junior High School students, the samples taken specifically for students in studying Civic, Citizenship and Human Rights Education. Research variables are the skills of process science and learning outcomes. Data taken by observation and tests and processed by regression analysis, one sample t-test and gain test. The results showed that this learning scenario was able to raise the science process skills to achieve an average score of 77.98, in a good category; the experimental class learning outcomes increased the average of N-Gain to 0.61 in the medium category, while the control class was only 0.21, in the low category. Based on the regression process science skills have a positive effect on learning achievement, by 72%. Evidently, the experimental class learning achievement is better than the learning achievement of the control class. It can be concluded that the learning model by giving before face-to-face meetings, discuss exchanging knowledge, can strengthen the mastery of the concept of student learning achievement.
