This research was quasi experiment research which used Posttest Only With Nonequivalent Control Group design by using the experimental 1 class (application of Problem Based Learning) and experimental 2 class (application of guided inquiry). The population studies are all X class students of SMA Negeri 3 Boyolali in academic year 2013/2014. Sampling tech- nique is using cluster sampling, the classroom that is chosen are X.1 as the experiment 1 class and X.3 as the experimental 2 class. The techique of collecting data is using essay test for measuring of SPS classifying, using tool and material, hypothesizing, formulate ways of working, predicting and communicating. Non-test technique is using methods of documentation and observation methods for measuring of SPS using the tool and materi- al, observing and experimenting. The data were analyzed by t-test assisted SPSS 16. The result of this research concluded that there are differences results between Problem Based Learning and guided inquiry toward student’s sciences process skills of X grade students at SMA Negeri 3 Boyolali. Key Words: Problem Based Learning, Guided Inquiry, Science Process Skills Pendahuluan Pembelajaran merupakan upaya yang dilakukan untuk memahami pengetahuan yang dipelajari. Pem- belajaran perlu menumbuhkan interaksi antara peserta didik dengan pendidik dan sumber belajar pada suatu lingkungan belajar. Belajar biologi pada tingkat SMA semestinya dibelajarkan dengan menumbuhkan interaksi peserta didik dan guru karena pembelajaran biologi menuntut pembelajran aktif yang akan melatihkan kemampuan intelegensi, keterampilan proses dan sikap ilmiah. Pembelajaran biologi sebagai sains harus dibelajarkan secara aktif yang mampu menumbuhkan proses atau kegiatan siswa dalam mempelajari gejala alam menggunakan pikiran dan sikap ilmiah. Pembelajaran biologi yang aktif mengembangkan kemampuan proses dan kemampuan belajar mandiri siswa dalam melihat, mengeksplorasi, memecahkan BIO-PEDAGOGI Volume 3, Nomor 2 Halaman 1-11 ISSN: 2252-6897 Oktober 2014
