Abstract

Paradigma pembelajaran yang berpusat pada siswa (learner centered) menuntut dan menantang guru untuk dapat memberdayakan siswa agar memiliki keterampilan proses sains dan hasil belajar siswa yang baik. Penelitian ini bertujuan untuk mengetahui pengaruh dan peningkatan penerapan model PBL pada mareti larutan elektrolit-nonelektrolit dan konsep redoks berbantuan media transvisi terhadap keterampilan proses sains dan hasil belajar siswa SMA Negeri 1 Randublatung. Desain yang digunakan dalam penelitian ini adalah pretest and postest group design. Teknik sampling yang digunakan yaitu cluster random sampling, diperoleh kelas X.A sebagai kelas eksperimen dan kelas X.C sebagai kelas kontrol. Hasil penelitian menunjukkan bahwa adanya pengaruh dan peningkatan yang signifikan penerapan model PBL berbantuan media transvisi terhadap keterampilan proses sains dan hasil belajar siswa. Besarnya pengaruh penerapan model PBL berbantuan media transvisi terhadap keterampilan proses sains dan hasil belajar siswa masing-masing 62,39% dan 49,43%. Peningkatan secara signifikan keterampilan proses sains dan hasil belajar siswa ditunjukkan dengan harga t paired berturut-turut 21,99 dan 28,21 lebih besar dari t tabel 2,03. Berdasarkan hasil penelitian dapat disimpulkan penerapan model PBL pada materi larutan elektrolit-nonelektrolit dan konsep redoks berbantuan media transvisi memberikan pengaruh dan peningkatan terhadap keterampilan proses sains dan hasil belajar siswa SMA Negeri 1 Randublatung.

Abstract

The aim of this research is to determine the effect of Cooperative Integrated Reading and Composition based Contextual Teaching and Learning. This research population is XI Sciences of senior high school 1 brebes 2011/2012. First data analysis showed that the population data are normally distributed and homogeneous, so the sampling technique which used is cluster random sampling. From the result of the draws, XI Science-1 as an experiment class (Cooperative Integrated Reading and Composition Based contextual Teaching and Learning) and XI Science-5 as a control class (conventional learning). Final data analysis showed that learning product both classes are normally distributed and have equal variances. In the test of correlation, obtained 0,732 of rb value, which showed a height correlation, so Cooperative Integrated Reading and Composition Based Contextual Teaching and Learning has height effect on student learning product in colloids. This learning contributes to student learning product=54%. The learning product of experiment and control class had reached completeness. classical learning completeness which achieved by experiment and control class are respectively 95% and 87,5%. The average value of affective and psychomotor in experimental class is better than the control class. Based on this research, we can conclude that Cooperative Integrated Reading and Composition based Contextual Teaching and Learning assisted has a positive effect on learning product in senior high school 1 brebes.

Abstract

The purpose of this research is to determine the influece of Think Talk Write (TTW) learning uses Contextual Teaching and Learning (CTL) on learning product. This research population is X of Senior High School 1 Kaliwungu 2011/2012. The sampling technique which used is cluster random sampling, the result of the draws XE as an experiment class (TTW learning uses CTL) and XD as a control class (conventional learning). The data agregation method in this research is documentation, test, observation, and questionnaire. Final data analysis showed that learning product both classes are normally distributed and have equal variances. In the test of correlation, obtained 0.520 of rb value, which showed a middle correlation. This learning contributes to student learning product is 27%. Classical learning completeness which achieved by experiment and control class are respectively 85.71% and 94.29%. The result of data analysis showed average value of kognitif learning product experiment class 78.6 and control class 70.8. The average value of affective and psychomotor in experimental class is better than the control class. Based on this research, we can conclude that TTW learning uses CTL has a positive influential on learning product in Senior High School 1 Kaliwungu.

Abstract

Penelitian tindakan kelas ini bertujuan untuk meningkatkan keterampilan proses sains kimia siswa melalui metode modelling learning dengan bantuan media video eksperimen. Melalui metode yang diterapkan, video eksperimen digunakan sebagai bentuk pemodelan keterampilan proses sains yang diajarkan kepada siswa. Penelitian dilaksanakan dalam dua siklus dimana setiap siklus terdiri atas perencanaan, tindakan, pengamatan, dan refleksi. Teknik pengumpulan data yang digunakan adalah teknik dokumentasi, observasi dan angket. Penilaian keterampilan proses sains siswa dilakukan dengan assesmen unjuk kerja menggunakan instrumen lembar observasi. Berdasarkan hasil pengamatan, ditunjukkan adanya peningkatan nilai keterampilan proses sains siswa yang signifikan sebesar 20,32% dari siklus I ke siklus II. Selain itu, nilai siswa pada setiap indikator keterampilan proses sains juga mengalami peningkatan. Indikator-indikator tersebut adalah mengamati, mengelompokkan atau mengklasifikasikan, menafsirkan, meramalkan, mengajukan pertanyaan, merumuskan hipotesis, merencanakan percobaan, menggunakan alat dan bahan, menerapkan konsep, dan mengkomunikasikan hasil. Berdasarkan hasil penelitian, dapat disimpulkan bahwa menerapkan modelling learning dengan video eksperimen dapat meningkatkan keterampilan proses sains kimia siswa.

Abstract

MAN has conducted research in Bradford 1 aims to find and how much influence the application of Active Learning SAVI based on the results of class X studying chemical redox subject matter. The study population numbered ten in class X class. This experimental method with random sampling cluster sampling, obtained by X-6 class of experiments are given in the class-based learning Active Learning SAVI, and the class of X-8 in a conventional classroom learning is given control. Two kinds of methods of data analysis, the preliminary data analysis including test for normality and homogeneity test results of eight classes normally distributed and homogeneous. Final data analysis also includes the results of normality test normal distribution of data, test the equality of two variances of two groups of results have the same variance of 1.1311. Hypothesis test is obtained by analysis of biserial correlation coefficient of 0.5269, the coefficient of determination of 27.76%, thoroughness studied in the classical style in the experimental class at 92.6%, while the control class by 76%. The average total score of affective and psychomotor aspects, experimental class achieved better grades than the control class. Based on opinion poll of students gained an average of students strongly agreed with the application of Active Learning teaching methods based on students Savi. Therefore, the experimental class students learn better than the control class.
