Abstract

ABSTRAK


 


Tujuan penelitian adalah mengetahui pengaruh model problem based learning (PBL) terhadap hasil belajar IPA peserta didik kelas VII  SMPN 11 Kota Bengkulu dalam materi pemanasan global. Penelitian yang diterapakan yaitu penelitian kuantitatif. Sampel penelitian diambil menggunakan teknik sampel random sampling yang sebelumnya telah diuji normalitas dan homogenitas diperoleh siswa kelas VII E. Jumlah siswa yang terlibat sebanyak 29 siswa yang terdiri dari 16 siswa laki-laki dan 13 siswa perempuan. Jenis penelitian ini adalah Pre-Experimental Design tipe One-Group Pretest-Postest Design. Teknik pengumpulan data menggunakan tes untuk hasil belajar IPA. Pengumpulan data hasil belajar siswa dilakukan dengan memberikan lembar soal berupa pretest (tes awal) dan postest (tes akhir) di setiap pertemuan. Hasil analisis data, dapat ditarik kesimpulan bahwa model problem based learning berpengaruh positif terhadap hasil belajar, yaitu hasil uji-t pada thitung sebesar 1.756 lebih besar dari ttabel sebesar 1.703. Sehingga Ho ditolak dan Ha diterima. Hasil ini juga memperkuat bahwa homogen, sehingga dapat disimpulkan bahwa ada pengaruh nyata (signifikan) variabel x (Pembeljaran IPA model Problem Based Learning) terhadap variabel Y (hasil belajar) dengan taraf signifikan 5%.

ABSTRACT


 


The purpose of the study was to determine the effect of the problem based learning (PBL) model on the science learning outcomes of seventh grade students of SMPN 11 Bengkulu City in the matter of global warming. The research applied is quantitative research. The research sample was taken using a random sampling technique that had previously been tested for normality and homogeneity, obtained by class VII E students. The number of students involved were 29 students consisting of 16 male students and 13 female students. The type of this research is Pre-Experimental Design type One-Group Pretest-Postest Design. Data collection techniques using tests for science learning outcomes. Data collection on student learning outcomes is done by giving question sheets in the form of pretest (initial test) and posttest (final test) in each meeting. The results of data analysis, it can be concluded that the problem based learning model has a positive effect on learning outcomes, namely the t-test results at tcount of 1,756 are greater than ttable of 1,703. So Ho is rejected and Ha is accepted. This result also strengthens that it is homogeneous, so it can be concluded that there is a significant (significant) effect of variable x (Problem Based Learning model of Science) on variable Y (learning outcomes) with a significant level of 5%.
