Abstract

Based on interviews and observation at VIII grade of SMP Negeri 1 Merbau Mataram Lampung Selatan showed that the student’s science prosess skill was low. This study aimed to determine the effect of guide inquiry model in increase student’s science process skill. The design pretest-posttest was non-equivalent. The sample were class VIII B and VIII C whice selected by cluster random sampling. Research data obtained from the pretest, posttest, and observation of student activity sheets. Analysis using the t test and U test using SPSS 16 and using student activity classification. Results of this study indicate that students' science process skills in the experimental class had no significant difference compared to the control class (experimental = 68.46; control= 66.06). Thus the use of guided inquiry model of the material structure and function of tissues in plants affect the students skill acquisition process.Berdasarkan hasil wawancara dan observasi kalas VIII SMPN 1 Merbau Mataram Lampung Selatan diketahui proses pengembangan ketrampilan proses sains masih rendah. Penelitian ini bertujuan untuk mengetahui pengaruh model inkuiri terbimbing terhadap keterampilan proses sains siswa. Desain penelitian ini pretest-postes tak ekuivalen. Sampel penelitian ini adalah kelas VIII B dan VIII C yang dipilih dengan teknik cluster random sampling. Data penelitian yang diperoleh dari pretes, postes, dan lemba robservasi aktivitas siswa. Analisis menggunakan uji t dan uji U dengan menggunakan program SPSS 16 serta mengunakan klasifikasi aktivitas siswa. Hasil penelitian ini menunjukkan bahwa keterampilan proses sains siswa pada kelas eksperimen memiliki perbedaan yang tidak signifikan dibanding kelas kontrol (eksperimen= 68,46; kontrol= 66,06). Dengan demikian penggunaan model inkuiri terbimbing pada materi struktur dan fungsi jaringan pada tumbuhan berpengaruh dalam penguasaan keterampilan proses siswaKata kunci : keterampilan proses sains, model inkuiri, struktur dan fungsi tubuh tumbuhan

Abstract

Students achievement is the ultimate goal is linked to the implementation of the learning process. Observations in X grade Senior High School 1 Natar, known that student activity and achievement is low. This study aimed to determine the effect of PBL models in improving student activity and achievement. The design was non-equivalent control group. The sample was class X3and X5 selected by purpossive sampling. This data is quantitative and qualitative form. Quantitative data obtained average value of the pretest, posttest and N-gain on Biodiversity material. Qualitative data obtained percentage average of students activities and responses of uses PBL models was analyzed descriptively. The results showed that the use of PBL models can improve student learning activities with an average of 66% it is also evident from the increase observed for all aspects. Students achievement in the experimental class also increase with average value of N-gain is 67,38. In addition, all students gave positive response to the use of PBL models. Thus, it can be concluded that the uses PBL models is influential in increasing the students activity and achievement. Keywords: biodiversity, PBL models, students learning activities and achievement.

Abstract

 Student involvement is one of the important factors in improving learning outcomes. Experimental method requires students to be more active in learning activities. Therefore, this study used an experimental method of inquiry and experimental verification. This study was aimed to compare of inquiry experiment method and verification of student learning outcome of cognitive and psychomotor. Design of this study was pretest-posttest non equivalent group. Samples were VIIA and VIID, chosen by purposive sampling. The data of research consist of quantitative data are student’s learning outcomes of cognitive aspect were analyzed using U-test and psychomotor aspect were analyzed by manner descriptive. Research results indicate using inquiry experiment method (N-gain 55.81) higher and significan be diffirent than verification experiment method (N-gain 43.17). The psychomotor of student learning outcome in inquiry experiment class (73%) as high as with verification experiment class (70%).Keterlibatan siswa merupakan salah satu faktor penting dalam meningkatkan hasil belajar. Metode eksperimen menuntut siswa menjadi lebih aktif dalam kegiatan pembelajaran. Oleh karena itu, penelitian ini menggunakan metode eksperimen inkuiri dan eksperimen verifikasi. Penelitian ini bertujuan mengetahui perbandingan metode eksperimen inkuiri dan verifikasi terhadap hasil belajar kognitif dan psikomotor. Desain penelitian pretest-posttest kelompok non-equivalen. Sampel penelitian siswa kelas VIIA dan VIID, dipilih secara purposive sampling. Data penelitian berupa data kuantitatif yaitu hasil belajar aspek kognitif siswa yang dianalisis menggunakan uji U dan hasil belajar aspek psikomotor yang dianalisis secara deskriptif. Hasil penelitian menunjukkan penggunaan metode eksperimen inkuiri (N-gain 55.81) lebih tinggi dan berbeda signifikan dibandingkan eksperimen verifikasi (N-gain 43.17).

The results of interviews with teachers in high school biology class XI Swadhipa Natar, it is known that subjects, especially biology subject matter Digestive System Food is delivered by using the method of discussion. Though this material has special characteristics that examine the mechanisms of complex processes that are difficult to understand, and involve organs that correspond to the structure and function of complex. The purpose of this study is to determine effect of Predict, Observe, Explain And (POE)  learning model  on student’s  learning activities  and mastering  of  Food Digestion System  concepts  of  Swadhipa  high school students. This  a quasi-experimental  strudy  used pretest-posttest  with non-equivalent dsigned. The  sample   were  students of  class   XI IPA2 as the experimental group and class XI IPA1 as a control  which was  selected from the population at random cluster sampling. Data was collected   as  in  percentage form.   The students’ actvities observed consists of five (5)  abilities of predicting, observing, describing, working together, and making conclusion. The study resulted that POE learning model  could enhanced the students’  predicting  ability  up to 20%,  observing ability up to 19%, describing ability up to 24%,  abity to work together up to 22,8%, and  ability of making onferences up to 16%

Abstract

The objective of this research was to find out the students’ critical thinking ability through TSTS and GW model in excretion system subject and students activity in teaching leaning process.The design of this research was pretest-posttest non equivalent. The research sample was students of XI IPA 1 as the first experimental class and XI IPA 2 as the second experimental class that was taken by cluster random sampling technique. The quantitative data was taken from pretest and posttest score and also N-gain that was analyzed by t-test on the level accurate of 95%. The qualitative data was the students’ critical thinking ability, data of students’ learning activities and questionnaire of students’ reaction on TSTS and GW model.The result of this research shown that TSTS model has been more increasing students’ critical thinking ability than GW model, it was shown by N-gain score on TSTS class (44,03) while in the GW class (32,30). The highest increasing indicator of students’ critical thinking ability was giving argument (32,74%), while the highest GW indicator was doing deduction (31,15%). The average of students’ activity in TSTS class was 84.44 while in GW class was 77,51. The highest activity in TSTS class and GW class occurred when changing information. Key words: Two Stay Two Stray, Gallery Walk, Critical thinking ability, Students’ activities, Excretion System
