<![CDATA[This study aims to determine whether there are differences in the average student learning outcomes taught with the Inquiry Training learning model and the Group Investigation learning model on electrolyte and non-electrolyte solution material. This research was conducted at SWADHARMA WERDHI AGUNG High School in second semester of 2017/2018. The research method used is the experimental method. Sampling is done by random sampling technique. The sample in this study was class XA students as experimental class I and class XB as experimental class II. Each sample amounted to 20 respondents, and the total number of respondents was 40. Data collection techniques were pretest and posstest and the instruments used to measure learning outcomes were multiple choice tests. Analysis of the posttest data of the two groups used the t test. The results of the research obtained were tcount of 2,233 and t table at a significant level of 0,05 of 2,024, then tcount> ttable. Then H0is rejected and H1is accepted. Thus it was concluded that there were differences in the average learning outcomes of students taught using the Inquiry Training learning model and the Group Investigation learning model.]]>

<![CDATA[The purpose of this study was to determine the application of the POGIL method to the learning outcomes of Grade X Science students on the mole concept material.This research was implemented in class X IPA 1 and X IPA 2 SMA Negeri 2 Langowan school year 2018/2019. The method used is experimental method with post – test only control design research. In this study applied different methods on 2 classes namely POGIL class and lecture class with the number of students of each class of 23 students. Student learning Data is derived from the post-test value. Data analysis uses test-T with a significant level of α = 0.05. Analysis of student learning statistics test results obtained the value T > T table or 4.31 > 1.68. So that the H1 can be concluded accepted and H0 rejected, this shows that students ' learning outcomes with the application of the POGIL method are greater than the student learning outcomes by the lecture method on the concept of Mole material.]]>

<![CDATA[This study aims to determine the effect of using the constructivist approach based on the 5E learning cycle on the learning outcomes of class XI students on buffer solutions. This research was conducted in classes XI IPA 1 and XI IPA 2 of Kotamobagu Christian High School. The method used is an experimental method with a post – test only control design. The research sample consisted of 23 randomly selected students. The experimental class uses the 5E learning cycle model, the control class uses conventional learning. Student learning outcomes data obtained from post-test scores. The analysis of research data shows that there are differences in student learning outcomes, which are taught using the 5E learning cycle model and those using conventional learning. The data analysis used the t-test with a significance level of α = 0.05. Statistical analysis of student learning outcomes obtained tcount> ttable or 4.90> 1.68. So it can be concluded that there are differences between student learning outcomes using the constructivism approach based on the 5E learning cycle and student learning outcomes using conventional learning.]]>

<![CDATA[The application of practicum methods efficiently is able to help educators to achieve success in the chemistry learning process. This study aims to determine student learning outcomes in corrosion material through the learning process by applying the practicum method. This research was conducted in the odd semester of the 2018/2019 academic year for students of class XII Science in YPPK High School St. Thomas Aquino Kaimana. The sample used in this study is all students of class XII IPA St. Thomas Aquino Kaimana. The indicator used in this study is individual success, that is, if the student has reached the value of 75. Analysis of the data in this study used the percentage completeness learning technique based on the results of the indicators obtained. The results showed that from the initial test of student learning outcomes had not reached completeness (value 75) with the percentage of completeness of learning outcomes of 0% and from the final test the results of student learning had reached a grade (value> 75) with a percentage of completeness of learning outcomes of 100%. Based on the results of this study it can be concluded that the learning outcomes of students in the subject matter of corrosion with the practicum method were increased.]]>

<![CDATA[Telah dilakukan penelitian model pembelajaran langsung pada siswa SMA Negeri 2 Tondano di semester genap tahun ajaran 2018/2019 bulan Januari-Februari 2019. Penelitian ini bertujuan untuk mengetahui hubungan model pembelajaran langsung dengan sikap siswa dan peningkatan prestasi belajar siswa pada materi larutan elektrolit dan nonelektrolit. Penelitian ini menggunakan metode eksperimen dengan desain penelitian one group pretest-posttest design. Populasi dalam penelitian ini adalah siswa kelas X IPA SMA Negeri 2 Tondano. Pengujian validitas instrumen soal diperoleh 10 soal yang valid dan 2 soal tidak valid, sedangkan pengujian reliabilitas instrumen soal diperoleh koefisien reliabilitas 0,785. Pengujian distribusi sikap positif siswa sebelum dan sesudah perlakuan diperoleh hasil bahwa sikap positif siswa tentang pembelajaran kimia meningkat. Berdasarkan hasil presentase selisih diatas menunjukkan bahwa sikap siswa dan prestasi belajar siswa mengalami kenaikan atau peningkatan.Hasil uji normalitas menunjukkan Lhitung<Ltabel untuk kelas eksperimen (0,10< 0,17) sehingga data berdistribusi normal. Maka dapat dilakukan uji hipotesis menggunakan uji korelasi Pearson Product Moment diperoleh nilai rxy = 0,602, selanjutnya uji signifikan nilai korelasi r kedalam nilai t dengan kriteria pengujian thitung > ttabel. Dari hasil perhitungan bahwa thitung (3.62) ttabel (2,06). Penelitian ini menyimpulkan bahwa terdapat hubungan antara model pembelajaran langsung dengan sikap siswa dan prestasi belajar siswa pada materi larutan elektrolit dan nonelektrolit.]]>

<![CDATA[Chemistry is a science that studies materials that are generally abstract in nature so many students find it difficult to understand the concept of chemistry which causes a lack of interaction between real life and chemical knowledge. This study aims to determine the effectiveness of the REACT strategy in improving student learning outcomes in buffering material at SMA Negeri 2 Langowan. The research method used is Quasi Experiment Design with research design is Posttest-only Control Group Design. The population is all students of class XI Science in SMA Negeri 2 Langowan even semester 2017/2018. The sample of this study were all students of class XI IPA 1, amounting to 25 people as the experimental class and all students of class XI IPA 2, amounting to 21 people as the control class. Data collected is processed from the results of Posttest. Data were analyzed using the Independent t-test formula to test the research hypotheses and obtained tcount> ttable (7.99> 2.02), so it can be concluded that the Contextual Teaching and Learning (CTL) learning method with REACT strategy proved to be effective against improving student learning outcomes in buffer material in class XI IPA of SMA Negeri 2 Langowan.]]>
