Abstract

This study aimed to compare the use of real media and picture media for improving student KPS. The design was pretest postest non equivalent group by purposive sampling, class X MIA 1 and X MIA 2 were choosen as research samples. Quantitative data were a student KPS that obtained from the average value of N-gain analyzed by t-test and U test. Qualitative data were percentage of the student KPS and student questionnaire that were analyzed descriptively. The results showed that the use of real media with average N-gain 61,95±13,18 was more affected improving student KPS significantly then picture media with average N-gain 34,45±16,20. Based on the observation sheet, the average of student KPS in real media class had high criteria (61%) while picture media class had medium criteria (46,13%). Most of the students gave positive responses to the use of real media (91,15%) and picture media (93,91%).Penelitian ini bertujuan mengetahui perbandingan penggunan media realia dan media gambar terhadap peningkatan KPS siswa. Desain penelitian adalah pretes postes kelompok non ekuivalen dengan purposive sampling sehingga kelas X MIA 1 dan X MIA 2 diambil sebagai sampel penelitian. Data kuantitatif berupa KPS siswa yang diperoleh dari rata-rata nilai N-gain dianalisis menggunakan uji-t dan uji U. Data kualitatif berupa  persentase KPS siswa dan tanggapan siswa dianalisis secara deskriptif. Hasil menunjukkan bahwa penggunaan media realia dengan rata-rata N-gain 61,95±13,18 lebih berpengaruh dalam meningkatkan KPS siswa secara signifikan dibandingkan dengan media gambar dengan rata-rata N-gain 34,45±16,20. Berdasarkan lembar observasi, rata-rata KPS siswa kelas media realia yaitu berkriteria tinggi (61%) sedangkan kelas media gambar yaitu berkriteria sedang (46,13%).

Abstract

The results of observation with X grades’ biology teacher of Persada Senior High School Bandar Lampung, there’s note that in the learning process students receive most information from teacher (teacher centered), so the effect forward to student learning activity and material mastery are still not optimal yet. One of the efforts to maximize it are using TGT models learning and  Flash Card media. The study aimed at inflence of TGT models with Flash Card media towards learning students’ activity and material mastery. This study uses design pretest-posttest not equivalent model with X3as experiments’ class (27 students) and X1 as controls’ class (30 students) was elected in cluster random sampling technique. The data of this study was obtained from the pretest and posttest, observation sheet and questionnaire of students respon about this study. Data analyzed using a t-test and u-test on the SPSS17 program. The results showed that average percentage of students learning activities in all aspect that observed in experiment class (77,62 %) was higher than control class (62,78 %), with an average N-Gain of material mastery on 65,89 % in experimental and control class on 38,65 %. In addition, 27 students was pleased to learn the matter of virus by using TGT models and Flash Card media. Thus, the used of TGT models and Flash Cards have influation toward students learning activities and material mastery of Virus as significantly. Keywords: TGT, Flash Card, material mastery, student learning activity, Virus.

Abstract

This research was aimed to know the effect of  examples non examples learning model towards cognitive achievement and students’ environmentally conscious attitude. This research design was pretest-posttest non-equivalent. Samples were VIID and VIIE that was chosen by purposive sampling. The quantitative data was obtained from cognitive achievement (pretest, posttest, N-gain) and analyzed by using t-test and U-test. The qualitative data was obtained from questionnaire and field notes were analyzed descriptively. The results showed that examples non examples learning model increased the average of  cognitive achievement although not significantly (59,19 increased to 70,36 with N-gain 26,02). Whereas students’ environmentally conscious attitude was categorized very high with average 85,01% from questionnaire and 90,91% from field notes. Thus, examples non examples learning model was influenced not significantly towards cognitive achievement and influenced towards students’ environmentally conscious attitude.Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran examples non examples terhadap hasil belajar kognitif dan sikap peduli lingkungan oleh siswa. Desain penelitian adalah pretes-postes non-equivalent. Sampel yaitu siswa kelas VIID dan VIIE yang dipilih secara  purposive  sampling. Data kuantitatif berupa hasil belajar (pretes, postes, N-gain) yang dianalisis menggunakan uji-t dan uji-U. Data kualitatif berupa kuesioner dan catatan lapangan mengenai sikap peduli lingkungan yang dianalisis secara deskriptif. Hasil penelitian menunjukkan model pembelajaran examples non examples meningkatkan rata-rata hasil belajar siswa walaupun tidak signifikan (59,19 meningkat menjadi 70,36, dengan N-gain 26,02). Sedangkan, sikap peduli lingkungan oleh siswa berkriteria sangat tinggi dengan rata-rata 85,01% yang didapat dari kuesioner dan 90,91% dari catatan lapangan. Dengan demikian, model pembelajaran examples non examples berpengaruh tidak signifikan terhadap hasil belajar kognitif siswa dan berpengaruh terhadap sikap peduli lingkungan oleh siswa. Kata kunci : examples non examples, hasil belajar kognitif, sikap peduli lingkungan
