PENGARUH MODEL PROJECT BASED LEARNING (PjBL) TERHADAP KETERAMPILAN PROSES PESERTA DIDIK PADA MATERI PERUBAHAN LINGKUNGAN FASE E SMA

Abstrak

Penelitian ini bertujuan untuk mengetahui perbedaan keterampilan proses sains peserta didik pada materi perubahan lingkungan antara peserta didik yang menggunakan model Project Based Learning (PjBL) dan yang menggunakan model pembelajaran langsung. Jenis penelitian yaitu eksperimen semu, dengan rancangan Posttest Only Control Group Design. Sampel penelitian yaitu kelas X E 5 dan X E 8 ditentukan dengan teknik purposive sampling. Metode pengumpulan data yaitu non tes mela   lui lembar observasi. Data diuji normalitas, homogenitas, dan hipotesisi menggunakan uji independent sample t-test dengan bantuan SPSS 22. Berdasarkan hasil penelitian diketahui bahwa keterampilan proses sains peserta didik kelas eksperimen lebih tinggi (81) dibandingkan kelas kontrol (64) hasil uji hipotesisi dilihat dari nilai signifikansi < 0.05 yaitu 0.000. Berdasarkan hasil uji hipotesis dapat disimpulkan bahwa terdapat pengaruh positif model Project Based Learning (PjBL) terhadap keterampilan proses sains peserta didik pada materi perubahan lingkungan fase E SMA.

This study aims to determine the differences in students' science process skills on environmental change material between students who use the Project Based Learning (PjBL) model and those who use the direct learning model. This type of research is a pseudo-experiment, with Posttest Only Control Group Design. The research sample is class X E 5 and X E 8 determined by purposive sampling technique. The data collection method is non-test through observation sheet. Data were tested for normality, homogeneity, and hypothesis using the independent sample t-test with the help of SPSS 22. Based on the results of the study, it is known that the science process skills of experimental class students are higher (81) than the control class (64) the results of the hypothesis test are seen from the significance value <0.05, namely 0.000. Based on the results of the hypothesis test, it can be concluded that there is a positive effect of the Project Based Learning (PjBL) model on the science process skills of students on the material of environmental changes in phase E of high school.
