Abstract

Based on the interviews with biology teachers and observation in the SMP Negeri 8 Bandar Lampung, the learning activities  and  student mastery of the concept was low. This study aimed to determine the effect of the use of TGT models in learning activities and increase student mastery of the concept. This study design was equivalent to the control group. The sample was class VIIG and VIIE are selected by purposive sampling. Quantitative data obtained from the average value of pretest, posttest and N-gain were analyzed using t-test or U test Qualitative data in the form of descriptions of students' learning activities. The results showed that the model improved the TGT student mastery of the concept with an average pretest score (47.97); posttest (71.49), and N-gain (0,45). Learning activity also increased by an average of 79.10% good enough. Thus, learning to use the TGT models significantly affect the activity of student.                                                                                      Berdasarkan  hasil wawancara dengan guru biologi dan observasi di SMP Negeri 8 Bandar Lampung, diketahui aktivitas belajar dan penguasaan konsep siswa masih rendah. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan model TGT dalam meningkatan aktivitas belajar dan penguasaan konsep siswa. Desain penelitian ini adalah kelompok kontrol ekivalen. Sampel penelitian ini adalah kelas VIIg dan V11e yang dipilih secara purposive sampling. Data kuantitatif diperoleh dari rata-rata nilai pretes, postes dan N-gain yang dianalisis menggunakan uji-t atau uji U. Data kualitatif berupa deskripsi aktivitas belajar siswa. Hasil penelitian menunjukkan bahwa model TGT dapat meningkatkan penguasaan konsep siswa dengan rata-rata nilai pretest (47,97); postest (71,49); dan N-gain (0,45). Aktivitas belajar juga mengalami peningkatan dengan rata-rata berkriteria cukup yaitu 79,10 %. Dengan demikian, pembelajaran menggunakan model TGT berpengaruh secara signifikan terhadap aktivitas belajar dan penguasaan konsep siswa. Kata kunci : aktivitas belajar siswa, model TGT,organisasi kehidupan, penguasaan konsep siswa

Abstract

This research aimed to know the comparison model LC with STAD model towards student’s learning activities and material mastery. This research design was pretest-posttest non equivalent group. Samples were VIIIA and VIIIC that was chosen by purposive sampling. The qualitative data of learning activities and student questionnaire responses which analyzed descriptively. The quantitative data obtained average value of pretest, posttest, and gain were analyzed using U-test. The result showed the STAD (0.61 value) improve student’s material mastery morethan LC (0.57 value). STAD gain of C2 indicator (0.52) and (0.97) LC; C4 indicator (0.55) STAD and (0.45) LC. The average learning activities all aspects (colaboration, search informatian, write opinions, presentation, ask question) STAD class (73.42) and (63.53) LC. Generally most of student (90.60%) gave positive response towards STAD and LC (87.56%). Thus, learning by using model STAD significan influence to improve student’s activities and material mastery.Penelitian ini bertujuan mengetahui perbandingan penggunaan model LC dengan STAD terhadap aktivitas dan penguasaan materi siswa.
