PENINGKATAN KUALITAS PEMBELAJARAN PPKN MELALUI PENERAPAN PROBLEM BASED LEARNING DI SMP

Penelitian ini bertujuan untuk meningkatkan kualitas pembelajaran PPKn melalui penerapan model Problem based learning di kelas VIII A semester 1 SMP Negeri 2 Manisrenggo Kabupaten Klaten tahun akademik 2014/2015. Penelitian ini merupakan penelitian tindakan kelas (classroom action research) dengan desain Kemmis & Taggart yang dilaksanakan dalam III siklus. Jenis tindakan yang dilaksanakan adalah penerapan model Problem based learning dalam pembelajaran PPKn. Langkah-langkah pembelajaran meliputi mengidentifikasi masalah, menggali sumber informasi yang relevan, belajar secara mandiri, menyelidiki dan menginterpretasi data yang terkumpul, memilih beberapa alternatif solusi masalah, dengan mempertimbangkan pendapat atau informasi dari kolabolator. Pengumpulan data dilakukan melalui observasi, tes tertulis, wawancara, dan catatan lapangan. Analisis data dilakukan secara kualitatif dengan teknik yang dikembangkan Miles dan Huberman. Hasil penelitian menunjukan bahwa penerapan model Problem based learning dapat meningkatkan kualitas pembelajaran PPKn pada aspek proses pembelajaran dan hasil belajar yang komprehensif (kognitif, afektif, dan psikomotorik). THE IMPROVEMENT OF THE CIVIV EDUCATION LEARNING QUALITY THROUGH THE APPLICATION OF THE PROBLEM BASED–LEARNING AT SMPAbstractThis study aimed to improve the Civic Education learning quality through the application of the problem- based learning model at Grade VIII A of SMP Negeri 2 Manisrenggo in semester 1 of the 2014/2015 academic year. This was a classroom action research (CAR) study employing the design by Kemmis & MacTaggart, carried out in three cycles. The action implemented was the application of the problembased learning model in the Civic Education learning. The learning steps included identifying problems, looking for relevant information sources, learning autonomously, investigating and interpreting the collected data, and selecting several alternative problem solutions by taking into account of opinions or information from the collaborator The data were collected through observations, tests, interviews, and field notes. The data were qualitatively analyzed using the technique developed by Miles and Huberman. The results of the study showed that the application of the problem-based learning model was capable to improve the Civic Education learning quality in the aspects of the learning processes and outcomes which were comprehensive (comprising cognitive, affective, and psychomotor aspects).

The aim of this study is to improve students' critical thinking skills through a problem based learning model in class IV SDN Ende 1. The type of research used in this study is classroom action research consisting of several interrelated cycles and the model chosen in this study is a Kemis and Mc Tagart model which consists of several stages namely planning, action, observation and reflection, where actions and observations are carried out together. The subjects of this study were 21 students in class IV SDN Ende 1. Based on the results of data analysis in classroom action research shows that the learning feasibility by applying the learning model Problem Based Learning has increased namely 81.5% in the first cycle and 94% in the second cycle, therefore it can be said that the learning process has been carried out very well and in accordance with the reference in the lesson plan that has been made. While the results of observations of student activities during learning by applying model of problem based learning have increased, which is proved by the increase in the average score of student learning activities in the first cycle by 55% and the second cycle by 87%. This improvement shows that during the learning process students were actively involved in solving problems. The results of the students’ critical thinking ability test of the first cycle can be seen that, there are 9 students or 43% who reach the KKM standard, while 12 students or 57% do not reach the value of 70 in accordance with the minimum completeness criteria set by the school. While the second cycle is known that as many as 21 students (100%) have succeeded and reached the indicator of critical thinking. The highest score obtained by student is 90 and the lowest score is 70 with an average value of 80% in the critical category. Therefore, the implementation of research by applying the problem based learning model ends in the second cycle . So, through research that has been done, by applying the Problem Based Learning model it is proven that it can improve the critical thinking skills of class IV students whose critical thinking test results are complete or meet the minimum completeness criteria (KKM).
