ABSTRAK
Tujuan penelitian ini adalah untuk mengetahui 1) perbedaan kemampuan berpikir kritis peserta didik antara penggunaan model Problem Based Learning, model Problem Based Learning disertai diagram Fishbone, dan model pembelajaran ekspositori, 2) perbandingan model Problem Based Learning dan model pembelajaran ekspositori terhadap kemampuan berpikir kritis peserta didik, 3) perbandingan model Problem Based Learning disertai diagram Fishbone dan model pembelajaran ekspositori terhadap kemampuan berpikir kritis peserta didik, dan 4) perbandingan model Problem Based Learning disertai diagram Fishbone dan model Problem Based Learning terhadap kemampuan berpikir kritis peserta didik kelas X IIS SMA Negeri 1 Surakarta Tahun Ajaran 2014/2015.
Metode penelitian yang digunakan adalah eksperimen semu dengan desain penelitian Posttest Only with Nonequivalent Control Group Design. Populasi dalam penelitian ini adalah seluruh peserta didik kelas X IIS SMA Negeri 1 Surakarta Tahun Ajaran 2014/2015. Teknik pengambilan sampel menggunakan sampling jenuh dengan hasil kelas X IIS 3 sebagai Kelas Kontrol, kelas X IIS 2 sebagai Kelas Eksperimen I, dan X IIS 1 sebagai Kelas Eksperimen II. Teknik pengumpulan data kemampuan berpikir kritis menggunakan tes dalam bentuk urian. Teknik analisis data menggunakan uji anava satu arah dan uji lanjut pasca anava dengan metode Scheffe’ pada taraf signifikan 5%.
Berdasarkan analisis data, dapat disimpulkan bahwa 1) terdapat perbedaan kemampuan berpikir kritis peserta didik antara penggunaan model Problem Based Learning, model Problem Based Learning disertai diagram Fishbone, dan model pembelajaran ekspositori, 2) model Problem Based Learning lebih efektif dibandingkan model pembelajaran ekspositori pada kemampuan berpikir kritis peserta didik, 3) model Problem Based Learning disertai diagram Fishbone lebih efektif dibandingkan model pembelajaran ekspositori pada kemampuan berpikir kritis peserta didik, dan 4) model Problem Based Learning disertai diagram Fishbone lebih efektif dibandingkan model Problem Based Learning pada kemampuan berpikir kritis peserta didik kelas X IIS SMA Negeri 1 Surakarta Tahun Ajaran 2014/2015.
Kata Kunci : Problem Based Learning, diagram Fishbone, kemampuan berpikir kritis
ABSTRACT
This research is intended to find : 1) differences in student’s critical thinking ability among applications of Problem-Based Learning Model, Problem-Based Learning Model with Fishbone Diagram, and Expository Learning Model, 2) comparison between Problem-Based Learning Model and Expository Learning Model towards student’s critical thinking ability, 3) comparison between Problem-Based Learning Model with Fishbone Diagram and Expository Learning Model towards student’s critical thinking ability, and 4) comparison between Problem-Based Learning Model with Fishbone Diagram and Problem-Based Learning Model towards student’s critical thinking ability of X Social Majors of State Senior Highschool 1 Surakarta in academic year of 2014/2015.
Type of this research is Quasi Experiment using Posttest-Only with Nonequivalent Control Group research design. Populations of this research are the whole students of X Social Majors of State Senior Highschool 1 Surakarta in academic year of 2014/2015. This research is using saturation sampling which results X Social 3rd class as the control class, X Social 2nd class as the 1st experiment class, and X Social 1st class as the 2nd experiment class. Data collecting techniques are using test. Data analysis is using One-way Anava test and Post-Anava test with Scheffe’s method with 5% significancy degree.
Based on data analysis, the results are as follow : 1) there are differences in student’s critical thinking ability among the applications of Problem-Based Learning Model, Problem-Based Learning Model with Fishbone Diagram, and Expository Learning Model, 2) Problem-Based Learning Model application is more effective towards student’s critical thinking ability compared to Expository Learning Model, 3) Problem-Based Learning Model with Fishbone Diagram is more effective towards student’s critical thinking ability compared to Expository Learning Model, and 4) Problem-Based Learning Model with Fishbone Diagram is more effective compared to Problem-Based Learning Model towards critical thinking ability of X Social Majors of State Senior Highschool 1 Surakarta in academic year of 2014/2015.
