Abstract

This research was aimed to know the influence ofpower pointteaching media towards students learning activities and conceptual understanding. Samples were VIIAand VIIB. The design of this research was pretest-posttest non-equivalent group. Quantitative data were obtained from the average of test scores that were analyzed using t-test and U-test. Qualitative data were students learning activities and questionnaire responses that analyzed descriptively. The result showed thatpower pointcan improved students learning activities with percentage 86,63%. Percentage of learning activities on cooperation team (96,53%), presentation discussion result (83,33%), asking question (88,19%), and making conclusion (78,47%). Conceptual understanding of students in experiment class were not significantlydifferent with control class,N-gainaverage was 15,89. In addition, most of the students (94%) gave positive responses towardspower point. Thus, usingpower pointwas good to improve students learning activities but not good to improve conceptual understanding.Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan mediapower pointterhadap aktivitas belajar dan penguasaan konsep siswa. Sampel penelitian adalah kelas VIIAdan VIIB.Desain penelitian ini adalah pretes postes kelompok tak ekuivalen. Data kuantitatif diperoleh dari rata-rata nilai tes yang dianalisis menggunakan uji-t dan uji-U. Data kualitatif berupa data aktivitas siswa dan tanggapan siswa yang dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa penggunaan mediapower pointdapat meningkatkan aktivitas belajar siswa dengan rata-rata persentase 86,63%. Aktivitas bekerjasama dalam kelompok (96,53%), mempresentasikan hasil diskusi kelompok (83,33%), mengajukan pertanyaan (88,19%), dan membuat kesimpulan (78,47%). Penguasaan konsep siswa kelas eksperimen tidak berbeda signifikan dengan penguasaan konsep siswa kelas kontrol, dengan rata-rataN-gain15,89. Selain itu, sebagian besar siswa (94%) memberikan tanggapan positif terhadap penggunaan mediapower point.Dengan demikian, mediapower pointbaik untuk meningkatkan aktivitas belajar namun kurang baik untuk meningkatkan penguasaan konsep siswa.Kata kunci: aktivitas belajar, penguasaan konsep siswa,power point

Abstract

Based on observation and interview with biology teacher  students critical thinking skill were not optimally developed yet. The experiment aims to find out the influence of applying pictured card media through NHT cooperative learning model  towards improvement of students critical thinking skill. This  quasi experiment study used  pretest posttest group non equivalent designed. Sample in this experiment are students from X2 and X4  class which obtained from population by cluster random sampling tehnique. Quantitative data  was obtained from   pretest and posttest scores which statistically analyzed with t-test using SPSS version 17 in 95% confidence levels. Qualitative data are student’s learning activities and students responses about applying  pictured card media through cooperative learning model type NHT which descriptively analyzed. Result of this study showed that the average of students critical thinking skill  improve significantly ( eksperimen class="70",64 control = 33,44). The average of student learning activities percentage in all observed aspects in experimental class showed  increased significantly  (eksperimen = 81,69% kontrol = 67,51%). The students (90,09%) also gives positive responses in appyling pictured card media through  NHT cooperative learning model. Keywords:  picture card media,, cooperative learning of NHT critical thinking skill, protista

This experiment was aimed to find out the improvement of students activity and learning outcome in global warming subject matter through active learning model. The design of this experiment was non equivalent pretest-posttest. The samples were sudents in VII3 and VII4 class which were chosen by purposive sampling. The quantitative data were obtained from pretest, posttest, and N-gain score that was analyzed by t-test. The qualitative data were sudents learning activity that was analyzed descriptively. The result of this study showed that using active learning model can improved the study result (N-gain 65,36). Students learning activity in experimental class showed the average precentage of 77,08%, while in control class the average precentage of 54,46%. Thus, there was influence of active learning in improving the activity and student learning outcomes in global warming matter.Tujuan penelitian ini untuk mengetahui peningkatan aktivitas dan hasil belajar siswa pada materi pemanasan global melalui model active learning.

Abstract

This research was purposed to know the influence of Problem Based Learning (PBL) model to increase students critical thinking skill and students learning activity. The samples were students of VIIA and VIIB SMP Padjajaran Bandar Lampung chosen by Purposive Sampling technique. The research used pretest-posttest non equivalent design. Quantitative data were pretest, posttest, and N-gain averages which were analyzed by using T-Test and U-Test. Qualitative data were from students activity sheet and responses that were analyzed descriptively. The increasing of critical thinking skill with N-gain average (50,54) was significantly different with control class (34,40). Activity of inducting, deducting, and evaluating were in medium criteria, problem identificating was in high criteria, argument giving was in very high criteria. Therefore, PBL improved critical thinking skill and students activity on material of environmental management.Penelitian ini bertujuan mengetahui pengaruh model Problem Based Learning (PBL) terhadap peningkatan kemampuan berpikir kritis dan aktivitas belajar siswa. Sampel penelitian adalah siswa kelas VIIA dan VIIB SMP Padjajaran Bandar Lampung, dipilih dengan teknik purposive sampling. Desain penelitian menggunakan pretest-posttest tak ekuivalen. Data kuantitatif berupa rata-rata pretest, posttest dan N-Gain yang dianalisis menggunakan uji-t dan uji U. Data kualitatif diperoleh dari lembar aktivitas belajar dan tanggapan siswa yang dianalisis secara deskriptif. Peningkatan kemampuan berpikir kritis siwa kelas eksperimen dengan rata-rata N-gain (50,54) berbeda signifikan dengan kelas kontrol (34,40). Aktivitas melakukan induksi, melakukan deduksi, dan melakukan evaluasi berkriteria sedang, merumuskan masalah berkriteria tinggi, memberi argumen berkriteria sangat tinggi. Dengan demikian, penggunaan model PBL dapat meningkatkan kemampuan berpikir kritis dan aktivitas belajar siswa pada materi pokok pengelolaan lingkungan.
