PENGARUH PENERAPAN METODE PRAKTIKUM TERHADAP AKTIVITAS BELAJAR DAN PENGUASAAN KONSEP OLEH SISWA
Get PDFThe result of interview were found that student’s learning activities and mastery of concept was low. This research aimed to understanding the activity progress of study also mastery student concept through practical method. The design method were equivalent pretest and postest. The sample were students of X2 and X4 class which chosen by cluster random sampling. The result shown that the student activity in every aspects in the experiment class was higher than the control class (experiment = 88,53%; control = 66,40%). Mastery of concept was increase too with a N-gain average of experiment was higher than control (experiment = 0,70; control = 0,35). Thus, practical methods could be increasing student’s learning activities and mastery the worls of plant concept. Hasil wawancara dengan guru biologi diketahui bahwa aktivitas belajar dan penguasaan konsep oleh siswa masih rendah. Penelitian ini bertujuan untuk mengetahui peningkatan aktivitas belajar dan penguasaan konsep siswa melalui penerapan metode praktikum. Desain penelitian ini pretes postes equivalen. Sampel adalah kelas X2 dan X4 dipilih secara cluster random sampling. Hasil penelitian menunjukkan bahwa aktivitas siswa dalam semua aspek yang diamati pada kelas eksperimen lebih tinggi dibandingkan dengan kelas kontrol (eksperimen = 88,53%; kontrol = 66,40%). Tingginya persentase aktivitas tersebut, mengakibatkan penguasaan konsep mengalami peningkatan, dengan rata – rata N-gain lebih tinggi dibandingkan kelas kontrol (eksperimen = 0,70; kontrol = 0,35). Dengan demikian, pembelajaran menggunakan metode praktikum berpengaruh dalam meningkatkan aktivitas belajar dan penguasaan konsep oleh siswa pada materi pokok dunia tumbuhan.

THE INFLUENCE OF MULTIMEDIA INTERACTIVE BY USING GUIDED INQUIRY LEARNING MODEL TO STUDENTS’ CRITICAL THINKING SKILL
No full textABSTRACTCritical thinking skill is important for students to overcome their daily life problem . Result of observation of class VIII SMP Negeri 1 Pardasuka, showed that students’ critical thinking skill was still low. The purpose of this research is to find out the influence of multimedia interactive by using guided inquiry learning model to students’ critical thinking skill. The aspecs of students critical thingking observed were to identify, to give example, to make differences, to interpretation, to generallized, to give assumption. Students activities observed were to give idea, to disscuss, to present, to answer questions, to ask question. This research used pretest posttest group non- equivalent designed. The sampel were students of class VIII E and class VIII F chosen at cluster randomly. The quantitative data was obtained from N-gain, and was analyzed by t-test at realibility of 5 %. Qualitative data were the students’ activity collected during process which was analyzed in the percentage of average. Students’ questionnaire responses on using multimedia interactive with guided inquiry learning was analyzed descriptively. The N-gain analysis of students critical thinking was 0,4 in average, meaning that the use of multimedia interactive using guided inquiry learning model influenced significantly toward students’ critical thinking.
