  The purpose of this study is to determine the effect of the problem based learning model of learning on students' ability to solve science problems at SMPN 1 Siman Ponorogo. That is because PBL learning models that take advantage of real-world (contextual) problems will provide opportunities for students to hone, grow, and improve their ability to solve science problems so that they can be applied in dealing with problems in daily life. This study uses a quantitative approach. This research method is quasi experimental design and the type of research used is experimental research with a non-equivalent group design experimental design. Data collection was performed using posttest questions which were then analyzed using inferential statistical data analysis techniques. The sampling technique used in this study is purposive sampling. The population in this study were all eighth grade students of SMPN 1 Siman. The sample in this study was class VIII A as an experimental class and Class VIII B as a control class. From the study obtained post test results which showed that the class with a problem based learning model through a contextual approach had a higher average value when compared to the class using conventional methods, namely 84.54 and 50.45. Hypothesis test results obtained tcount> ttable is 11.747> 1.681, so Ha is accepted and H0 is rejected. From these calculations it can be concluded that there is a significant influence on the Problem Based Learning model through a contextual approach to the ability to solve science problems of Grade VIII students at SMPN 1 Siman Ponorogo.

The current learning process of students is directed in a one way process. The teachers have to explain and the students are listening to them instead of being actively involved. It degrades their cognitive learning outcome. The application of Think Pair Share affects the students to become actively involved and giving an opportunity for those who want to comprehend their argument into the class. The additional approach of the method may support to make the students feel their own learning method which goes meaningful. The goal of this research is to know the role of Think Pair Share learning method toward the cognitive learning outcome of senior high school students. The research uses quassi experiments in terms of control class and experiment class approach. The result shows that the reduction of them are 33,53 and 17,21. The normality test result defines that the significance value is 0,0066 (>0,05). It means they have accepted H0, meanwhile the pretest and posttest mark of each class control and experiment distribute normally. The homogeneity test results show a value of 0.439 (> 0.05) so that H0 is accepted, which means that the pretest and posttest values from the experimental and control classes come from the same or homogeneous population. The result of ANACOVA test show that SPSS result is 0,000 (>0.05) so the H1 is accepted. It proves that Think Pair Share method using observation experiment is effectively significant towards the cognitive learning outcome of the students. From this situation, it concludes that the approach is having an impact into the cognitive learning outcome of the students
