Tujuan penelitian untuk mengetahui pengaruh pembelajaran fisika melalui Problem Based Learning (PBL) menggunakan metode eksperimen dan metode demonstrasi ditinjau dari kemampuan berfikir kritis dan kemampuan berfikir kreatif dan interaksinya terhadap hasil belajar kognitif, afektif, dan psikomotor.
Penelitian merupakan penelitian eksperimen dengan desain faktorial 2x2x2. Populasi penelitian adalah seluruh siswa kelas X SMA Negeri 4 Madiun tahun pelajaran 2014/ 2015. Sampel diperoleh dengan teknik cluster random sampling terdiri dari 2 kelas X B dan X C. Pengumpulan data menggunakan teknik tes untuk hasil belajar kognitif, kemampuan berfikir kritis, dan kemampuan berfikir kreatif. Hasil belajar afektif dan psikomotor menggunakan checklist. Analisis instrument soal menggunakan program QUEST. Analisis data hasil penelitian menggunakan program SPSS 18.
Hasil dari penelitian :1) tidak terdapat perbedaan pengaruh pembelajaran Problem Based Learning (PBL) menggunakan metode eksperimen dan demonstrasi terhadap hasil belajar kognitif, afektif, dan psikomotor; 2) tidak terdapat perbedaan pengaruh kemampuan berfikir kritis terhadap hasil belajar kognitif, afektif, dan psikomotor; 3) terdapat perbedaan pengaruh kemampuan berfikir kreatif terhadap hasil belajar kognitif, tidak terdapat perbedaan pengaruh kemampuan berfikir kreatif terhadap hasil belajar afektif dan psikomotor; 4) tidak terdapat pengaruh interaksi metode pembelajaran ditinjau kemampuan berfikir kritis terhadap hasil belajar kognitif, afektif, dan psikomotor; 5) tidak terdapat pengaruh interaksi metode pembelajaran dan kemampuan berfikir kreatif terhadap hasil belajar kognitif, afektif, dan psikomotor; 6) tidak terdapat pengaruh interaksi kemampuan berfikir kritis dan kemampuan berfikir kreatif terhadap hasil belajar kognitif, afektif, dan psikomotor; 7) tidak terdapat interaksi pengaruh metode pembelajaran, kemampuan berfikir kritis, dan kemampuan berfikir kreatif terhadap hasil belajar kognitif, afektif, dan psikomotor.

ABSTRACT
This research is aimed to know the effect of learning physics the Problem Based Learning (PBL) using experiment and demonstration methods viewed from critical and creative thinking abilities and the interaction on student achievement.
The method of the research used an experiments with factorial design 2x2x2. Population of the research were all students grade ten in SMA Negeri 4 Madiun in the academic year of 2014-2015. The samples of the research were determined by cluster random sampling consisting of 2 classes X B and X C. Test was used as data collection technique to measure cognitive achievement, critical and creative thinking ability. In addition, affective and psychomotor achievement were collected using checklist. The results of test was analyzed using QUEST. Furthermore, the research result was analyzed using SPSS 18.
The result of the research: 1) there is no difference in the effect of learning the Problem Based Learning method using experiment and demostration methods toward cognitive, affective and psychomotor achievement; 2) there is no difference in the effect of critical thinking ability toward cognitive, affective and psychomotor learning results; 3) there is difference in the effect of creative thinking ability toward cognitive learning results, while there is no difference in the effect of critical thinking ability toward affective and psychomotor learning outcomes. 4) there is no effect interaction of learning method viewed from critical thinking ability on cognitive, affective, and psychomotor learning results;  5) there is no effect interaction between learning method and creative thinking ability toward cognitive, affective and psychomotor learning outcomes; 6) there is no effect interaction between critical and creative thinking abilities toward cognitive, affective and psychomotor learning outcomes; 7) there is no effect interaction among learning methods, critical and creative thinking abilities toward cognitive, affective and psychomotor learning outcomes.
Key Words: Problem Based Learning (PBL), experiment, demonstration, critical thinking ability, creative thinking ability.
