Pengaruh Model Problem Based Learning Berbantuan Infografis Terhadap Peningkatan Interpersonal Skill Siswa Materi Kegiatan Ekonomi
The Influence of Problem-Based Learning Models Assisted by Infographics on Improving Students' Interpersonal Skills on Economic Activity Materials
Penelitian ini bertujuan untuk mengetahui pengaruh peningkatan
Interpersonal skill siswa Sekolah Menengah Pertama (SMP) dengan
pembelajaran Problem_Based_Learning berbantuan Infografis dan
pembelajaran umum. Jenis Penelitian yang digunakan adalah Quasi
Eksperimental atau Eksperimen semu menggunakan desain Post-
test_Only_Control_Group_Design. Jumlah subjek penelitian
berjumlah 59 siswa, 29 siswa kelas kontrol (umum) dan 30 siswa
kelas eksperimen (Problem Based_Learning berbantuan Infografis).
Instrumen yang digunakan adalah Soal Uraian, Observasi dan
Angket/kuisioner. Perolehan hasil dididukung dengan hasil rata
rata hasil observasi Interpersonal Skill pada kedua kelas yaitu kelas
eksperimen (81,6%) dengan kategori Sangat Aktif kemudian kelas
kontrol (45,1%) dengan kategori Cukup. Hasil penelitian yang
diperoleh berdasarkan Uji Independent Sample T-Test, hipotesis
pertama yang diperoleh menyatakan bahwa ada peningkatan nilai
hasil post-test siswa setelah menggunakan pembelajaran Problem
Based_Learning berbantuan Infografis diperoleh kelas eksperimen
dengan nilai rata rata 84,70 dengan standar deviasi 6.607 lebih tinggi
dibandingkan pada kelas_kontrol yaitu 62,97 dengan standar
deviasi 7.394. Hipotesis kedua diperoleh nilai sig 0,003 < 0,005, dan diperoleh (df = 28) maka nilai t hitung lebih dari t tabel adalah 3.390
> 1.701, Artinya ada pengaruh pada penggunaan model
pembelajaran Problem_Based_Learning berbantuan Infografis
terhadap peningkatan Interpersonal Skill siswa.
This study aims to determine the effect of improving the interpersonal
skills of junior high school (SMP) students by Problem_Based_Learning
assisted by infographics and general learning. This study uses a Quasi
Experimental type using a Post-test_Only_Control_Group_Design type of
design. The number of research subjects conducted was 59 students, 29
students in the control class (general) and 30 students in the
experimental class (Problem_Based_Learning assisted by Infographics).
The instruments used are Problem Description, Observation and
Questionnaire. The results obtained are supported by the average
results of Interpersonal Skill observations in both classes, namely the
experimental class (81.6%) in the Very Active category and the control
class (45.1%) with the Enough category. The results obtained based on
the Independent Sample T-Test, the first hypothesis obtained stated
that there was an increase in the post-test scores of students after using
Infographic-assisted Problem Based Learning, the experimental class
obtained an average value of 84.70 with a standard deviation of 6.607
higher than in the control class that is 62.97 with a standard deviation
of 7394. The second hypothesis obtained a sig value of 0.003 < 0.005, and obtained (df = 28) then the value of t count more than ttable is 3.390
> 1.701, which means that there is an influence on the use of the
Problem_Based_Learning model with the help of infographics on
improving students' Interpersonal Skills.
