Abstract

This study was aimed to know the influence of using remedial modules learning material on the minimum completeness criteria (MCC) student achievement. The research design was equivalent control group. Samples were all of the VIII class who have remedial and was selected by purposive sampling. The research data were quantitative and qualitative. The quantitative data were the average of pretest, posttest and gain were analyzed by U-test. The qualitative data was the student responses questionnaire were analyzed decriptively. The results showed that student achievement was increase with value average of pretest (35.38); posttest (73.42); and gain (0.59). The most of students (90.44%) gived positive respond to the using of remedial modules learning material. Thus, learning use remedial modules learning material influence to increas the MCC in the Human Circulatory System subject matter. Penelitian ini bertujuan untuk mengetahui pengaruh bahan ajar modul remedial terhadap pencapaian kriteria ketuntasan minimal (KKM) siswa. Desain penelitian adalah kelompok kontrol ekivalen. Sampel penelitian adalah seluruh kelas VIII yang mengalami remedial dan dipilih secara purposive sampling. Data penelitian berupa kuantitatif dan kualitatif. Data kuantitatif diperoleh dari rata-rata nilai pretest, postest dan gain yang dianalisis menggunakan uji U. Data kualitatif berupa angket tanggapan siswa yang dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa hasil belajar mengalami peningkatan dengan rata-rata nilai pretest (35,38); posttest (73,42); dan gain (0,59). Sebagian besar siswa (90,44%) memberikan tanggapan positif terhadap penggunaan bahan ajar modul remedial. Dengan demikian, pembelajaran dengan menggunakan bahan ajar modul remedial berpengaruh dalam meningkatkan KKM siswa pada materi pokok Sistem Peredaran Darah Manusia.  Kata kunci : hasil belajar kognitif siswa, modul remedial, sistem peredaran darah manusia

Abstract

This research aimed to know the effect of Problem Based Learning (PBL) for improving students learning activities and students learning outcomes on environment subject matter. Samples were X5 and X6 from SMA N 1 Trimurjo 2013/2014 academic year that was choosen by purposive sampling. The research design was pretest-postest non equivalent. The quantitative data were students learning outcomes from pretest, postest score which analyzed using t-test and U-test. The qualitative data were students learning activities data, questionnaire responses that were analyzed descriptively. The result showed that the average of learning activities increased in every aspect with adequate criteria (68,18). Most of students (77,27%-95,45%) gave positive responds and involved in PBL. PBL model improved students learning outcomes with N-gain average on medium criteria (67,98%). N-gain average of C4 indicator cognitif on experiment class was significantly different but was not significantly different on N-gain average of C2 indicator cognitif.Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan model Problem Based Learning (PBL) dalam meningkatkan aktivitas dan hasil belajar siswa pada meteri pokok lingkungan. Sampel penelitian adalah siswa kelas X5 dan X6 SMA N 1 Trimurjo tahun pelajaran 2013/2014 yang dipilih secara purposive sampling. Desain penelitian adalah pretes postes tak ekuivalen. Data kuantitatif diperoleh dari nilai pretes-postes yang dianalisis menggunakan uji-t dan uji-U. Data kualitatif berupa data aktivitas, angket tanggapan dan keterlibatan siswa yang dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa aktivitas belajar meningkat di setiap aspek dengan kriteria cukup (68,18). Sebagian besar siswa (77,27%-95,45%) memberikan tanggapan positif terhadap model PBL dan terlibat dalam proses pembelajaran PBL.

Abstract

This research was aimed to know the effect of  student work sheet (SWS) based science process skill (SPS) towards student SPS. This research design was pretest-post test non-equivalent group. Samples were VIIC and VIIF that was chosen by purposive sampling. Quantitative data was obtained from the average value of test and analyzed by using t-test and U-test. Qualitative data was description of  student SPS, learning activities data and questionnaire responses were analyzed descriptively. The results showed that the students SPS was still low, it was proofed by pretest average 13.07; post test average 25.75; and N-gain average 0.15. N-gain average on observation skils 0.17; interpretation skill 0.08; and communication skill 0.33. Whereas students average of learning activities was 60.25% with middle criteria. Beside that, the most of students (92.5%) gave postive responsed towards SWS based SPS. Thus, learning used SWS based SPS was influenced not significantly to improve students SPS. Penelitian ini bertujuan untuk mengetahui pengaruh lembar kerja siswa (LKS) berbasis  keterampilan proses sains (KPS) terhadap KPS siswa. Desain penelitian adalah  pretes-postes kelompok tak ekuivalen. Sampel yaitu kelas VIIC dan VIIF yang dipilih secara  purposive sampling. Data kuantitatif diperoleh dari rata-rata nilai tes yang dianalisis menggunakan uji-t dan U.

Abstract

Observation results show that mastery of the Virus subject matter on grade X Swadhipa’s student Senior High School in Natar is still low. This research aims to know the influence of the using picture cards media on students learning activities and mastering of the Virus subject matter for students. This research was quasi experimental design with unequivalent pretes postes group. The research samples are grade X1 and X2 which are selected from population by cluster random sampling. This research data is in quantitative and qualitative data. Quantitative data is obtained from the average of pretes and postes value which is analyzed statistically with t-test at 95% confidence levels using SPSS 17 program. Qualitative data is analyzed by descriptive analysis in percentage value. The research data is obtained from the student activity observation forms, and students' responses on using of flash cards media with NHT model. The research result shows that the average of mastering on subject by group students experiment is greater than control group (experiment = 79,1; control = 70,20). Moreover, the average of increasing the mastery of all observation indicators are greater than class control (experiment = 48,28; control = 43,22). The average of increasing percentage of student activity to all obeservation aspects in class experiment are greater than class control (experiment = 85,18; control = 76,30). In addition, the majority of students give positive response on using of flash cards media. Thus, learning process use flash card media with NHT learning model effects to improve the learning activity and mastery of the Virus subject matter on students.  Keywords: Flash Card, NHT, Learning Activity, Mastering Subject, Virus
