Abstract

This study was aimed to determine the effect of TGT learning model and flash card media toward students learning activity and material understanding. This study was designed using not equevalent group pretest posttest design. The samples were students of grade X1 and X2 and it was established by purposive sampling. The qualitative data of students learning activity was collected by observation sheet, and students respons was collected by questionnaire, then it was analyzed descriptively. The quantitative data of material understanding was collected by an average value of pretest, posttest and N-Gain, then it was analyzed statistically using t-test and U-test. The results of this study showed an increased students learning activity with percentage 80,16% as high criteria, but it was not influence significantly to students material understanding of Plant Kingdom. The N-gain average of material understanding on C1 indicator was 92,8617,93; and C3 indicator was 32,7127,79 were not different significantly. While, C2 indicator was 86,5424,13 different significantly.Penelitian ini bertujuan untuk mengetahui pengaruh penerapan model pembelajaran TGT dengan media kartu bergambar terhadap aktivitas belajar dan penguasaan materi oleh siswa. Desain penelitian adalah pretes-postes kelompok tak ekuivalen. Sampel penelitian adalah siswa kelas X1 dan X2 yang dipilih secara purposive sampling. Data kualitatif berupa aktivitas belajar yang diperoleh melalui lembar observasi, dan tanggapan siswa diperoleh melalui angket, kemudian dianalisis secara deskriptif. Data kuantitatif berupa penguasaan materi siswa diperoleh dari rata-rata nilai pretes, postes, dan N-gain, kemudian dianalisis secara statistik menggunakan uji-t dan uji-U. Hasil penelitian menunjukkan peningkatan rata-rata aktivitas belajar yaitu 80,16% dengan kriteria tinggi, namun tidak berpengaruh signifikan terhadap peningkatan penguasaan materi Dunia Tumbuhan. Rata-rata N-gain penguasaan materi pada indikator C1 sebesar 92,8617,93; dan indikator C3 sebesar 32,7127,79 tidak berbeda signifikan, namun indikator C2 sebesar 86,5424,13 berbeda signifikan.Kata kunci: aktivitas belajar, kartu bergambar, penguasaan materi, TGT

Abstract

Based on observations and interviews with Biology teacher at SMP N 19 Bandar Lampung obtained information that eighth grade learning outcomes is still low at only 22.22% of students who achieved mastery Minimal Criteria (KKM). This is presumably due to the use of a variety of media as a tool in learning is still rare. Therefore it is necessary to use a medium that media can make students more actively in learning that results belajarpun increased. The purpose of this study was to mengetahuai realia media effectiveness through guided inquiry model of the learning activities and students' mastery of the material. The research design was a pretest posttest non-equivalent, with sempel retrieval technique using a cluster random sampling. Quantitative research data is data is data mastery of the material obtained from the pretest-posttest values were then calculated with the formula N-Gain scores and data analysis using t-test at the 95% level of belief. Qualitative data in the form of student activity data and questionnaire responses of students drawn from the observation. The results of this study indicate an improvement of the control of matter on a class that uses a media realia through guided inquiry models with average pretest ratat the 3.11 increase to the average post-test is 7.78 with N-gain of 68.54. Likewise with student learning activities, from five aspects of student learning activities observed was evident in the first meeting with the average value of learning activities by 60.95% increased to 75.05% in the second peretemuan. As for the students' responses on the effectiveness of media use realia through guided inquiry model of general students were pleased with the learning that has been done.

Abstract

This study aimed to determine the effectiveness of U, chevron and theater seating formation on student learning outcomes in the subject matter of the plant tissues in Senior High School 3 Metro. The population was XI grade science students and samples were XI science 1, XI science 2, and XI science 3 grade’s students which were selected by purposive sampling technique. The design of this study was a non-equivalent pretest-posttest. Measurement of effectiveness on cognitive aspects based on differences in N-gain, while the calculation of affective and psychomotor aspects based on the interpretation of Qualitative Achievement Index and score improvement calculation. The results showed that the average N-gain value, affective and psychomotoric aspects of the experimental class I was higher than the experimental class II and control class. In conclusion, there were differences in the effectiveness of the three seating formations that are determined against learning outcomes and the U was the most effective then chevron and theater formations.Penelitian ini bertujuan mengetahui efektivitas formasi tempat duduk tipe U dan Chevron terhadap hasil belajar peserta didik pada materi pokok jaringan tumbuhan di SMAN 3 Metro.

Abstract

Mastery of concepts that are not quite optimal by high school science students of class IX N 2 Metro affected by the lack of proper strategies in the learning process. Strategies that can facilitate student achievement and skill one is mind mapping. Using mind mapping aims to determine students' critical thinking skills. Experimental research design was pretest-posttest form is not equivalent to involve XI IPA1 as the experimental class and control class XI IPA2 as selected by purposive sampling technique. The research data in the form of qualitative data obtained from students 'learning activities are analyzed using an index of students' critical thinking skills and mind mapping products derived from each group discussions and quantitative data obtained from a pretest-posttest were analyzed using t-test. The results showed improvement in the experimental class students' mastery of concepts with an average gain of 64.73 N-higher than the average N-gain the control class is 47.52. The average increase in each indicator of cognitive mastery of concepts by students in the experimental class also higher at 41.27 while the control class is 31.55. Similarly, student learning activities, that the experimental class achieving increased higher activity than the control class. Aspects express opinions / ideas and discuss work on LKS is the highest activity obtained by the students. Based on the achievements that have been disclosed, it can be concluded that the mind mapping is effective in improving students' critical thinking skills.
