Based on these facts it can be concluded that there is influence of guided inquiry learning model toward physics learning outcome of students. Keywords: guided inquiry learning model, learning outcomes.

Fcount (8,857) > Ftable (3,97). Tujuan penelitian ini adalah untuk mengetahui pengaruh pendekatan pembelajaran multi representasi terhadap hasil belajar fisika, pengaruh motivasi belajar peserta didik terhadap hasil belajar fisika, dan interaksi antara pendekatan pembelajaran multi representasi dengan motivasi belajar peserta didik terhadap hasil belajar fisika. Jenis penelitian ini adalah quasi experiment dengan desain penelitian kelompok non-ekuivalen. Pengambilan sampel menggunakan teknik purposive sampling, sehingga diperoleh kelas XI MIA 1 Test the effect of students learning motivation on physics learning equal to Fcount (9.00) > Ftable (3,97). Test the interaction between the multi representational learning approach and the students learning motivation toward the learning outcomes of physics equal to Fcount (2.00) < Ftable (3,97). Based on these facts it can be concluded that there is influence of multi representation learning approach to physics learning result, there is influence of learning motivation learners to physics learning result, and there is no interaction between multi-

A thin layer of tin oxide with doping Fluorine was synthesized using the sol-gel spin coating method. The synthesis aims to determine the quality of thin layers formed based on temperature variations and the number of layers. The basic material used is SnCl2.2H2O, while the doping material used is NH4F with variations in concentrations of dopants 0, 5, 10, 15, 20 and 25%. The substrate used is glass with a size of 10 x 10 x 3 mm. The synthesis of the thin layer includes substrate preparation, sol-gel making, thin film making, and heating process. At this stage SnO2:F is deposited on a glass substrate with sol-gel spin coating technique at the concentration of sol 1 M with doping levels of Fluorine 0, 5, 10, 15, 20 and 25%, and treated with maturation for 24 hours. Making a thin layer using a spin coater at a speed of 2000 rpm for 3 minutes. The layer made consists of one layer, two layers, three layers and four layers. The resulting layer shows that the higher the doping percentage, the higher the transparency of the layer. In addition, the more the number of layers, the lower the transparency level. Keywords: Thin Film, Tin Oxide, Fluorine, Sol-gel, Spin Coating

This study aims to determine the effect of guided inquiry learning model toward critical thinking skills of students. This type of research is quasi experiment with non-equivalent group design. Sampling using purposive sampling technique, so that obtained class XI MIA 1 as experiment class and class XI MIA 2 as control class. The research instrument is a essay test of 5 questions that have been tested for validity, reliability, level of difficulty, and different power of problems. The learning data of the two classes is normally distributed. Based on the homogenity data obtained both homogeneous. Data were analyzed by MANOVA test. Result of data analysis show significance  0,021 if  determined the level of significance 0,05 then 0,021<0,05. Based on these facts it can be concluded that there is influence of guided inquiry learning model toward critical thinking skills of students.

Abstract-This study aims to determine the effect of structured inquiry learning model with scientific approach on student's critical thinking skills and physics learning outcomes of class X in SMAN 1 Gerung in academic year 2014/2015. The study uses a quasi experiment with design untreated control group design with pretest and posttest. The sample was selected by clauster random sampling and obtained class X-3 as the experiment class using structured inquiry learning model with scientific approach and class X-6 as the control class using expository learning model. Data post-test were tested for normality, homogeneity, and hypothesis test. Hypothesis test using t-test polled variance with 5% of significance level. The results of the study were obtained: (1) there was the effect of structured inquiry learning model with scientific approach on student's critical thinking skills ( = 5.78 > = 1.9983) and (2) there was the effect of structured inquiry learning model with scientific approach on student's physics learning outcomes ( = 4.39 > = 1.9983). This indicates that the structured inquiry learning model with scientific approach is better than the expository learning model. Expected to do further research on structured inquiry learning model with scientific approach that measure the other of higher order thinking skills. Keywords: structured inquiry learning model, scientific approach, critical thinking skills, and physicslearning outcomes. PENDAHULUANPada hakikatnya setiap manusia membutuhkan pendidikan, karena pendidikan itu sendiri merupakan salah satu kunci kehidupan. Dengan adanya pendidikan yang dimiliki oleh seseorang maka kehidupannya menjadi lebih baik dan lebih terarah. Tujuan pendidikan itu sendiri adalah untuk menciptakan seseorang yang berkualitas dan berkarakter, sehingga memiliki pandangan yang luas ke depan guna mencapai cita-cita yang diharapkan dan mampu beradaptasi secara cepat dan tepat terhadap perubahan kondisi lingkungan kehidupan terutama adanya perubahan zaman yang berkembang begitu pesat.Kualitas pendidikan di Indonesia saat ini sangatlah memprihatinkan. Hal ini dapat terlihat pada mutu pendidikan Indonesia yang begitu rendah jika dibandingkan dengan negara-negara tetangga seperti Malaysia, Singapura, Brunai Darussalam, dan Thailand. Hasil riset yang dilakukan oleh UNDP (United Nations Development Programme) terhadap Human Development Index (HDI) yang dirilis pada tahun 2010, Indonesia menduduki peringkat ke-108 dari 169 negara [1]. Oleh karena itu, diperlukan upaya meningkatkan mutu pendidikan di Indonesia.Mutu pendidikan salah satunya ditentukan di dalam kelas melalui proses pembelajaran, khususnya dalam penelitian ini adalah proses pembelajaran fisika.Fisika merupakan salah satu bagian dari ilmu pengetahuan alam (IPA). Pada hakikatnya IPA merupakan suatu produk (a body of knowledge), proses (a way of investigating), dan sikap (a way of thinking). Jadi, dapat diambil persepsi bahwa hakikat fisika sama dengan hakikat IPA [2]. Berdasarkan hakikat fisika ini tersirat jelas bahwa yang diingi...
