Abstract

Latar belakang penelitian ini adalah rendahnya kemampuan berpikir kritis siswa. Rendahnya kemampuan berpikir kritis siswa disebabkan oleh aktivitas belajar yang masih berfokus pada latihan soal dan pemberian tugas, serta metode pembelajaran yang lebih dominan berupa ceramah. Tujuan penelitian ini adalah untuk mengetahui pengaruh model Problem Based Learning (PBL) terintegrasi etnosains terhadap kemampuan berpikir kritis siswa di SMPN 4 Payakumbuh. Jenis penelitian ini kuantitatif dengan metode quasi eksperimen melalui rancangan non-equivalent control group design. Sampel penelitian diambil dengan menggunakan teknik purposive sampling. Data diperoleh melalui pemberian pretest dan posttest, lalu dianalisis secara kuantitatif. Analisis instrumen tes menggunakan uji statistik berupa uji prasyarat dan uji hipotesis. Uji hipotesis yang dilakukan menggunakan uji-t menghasilkan thitung sebesar 3,429 yang lebih tinggi dari ttabel sebesar 1,998. Temuan ini mengindikasikan bahwa H0 ditolak, yang berarti ada perbedaan signifikan secara statistik terkait kemampuan berpikir kritis siswa yang diajar dengan model PBL terintegrasi etnosains.

Abstract

The purpose of this article is to determine whether the effect of differentiated learning processes with the Problem Based Learning (PBL) model on students' critical thinking skills at SMP Negeri 1 Candung. The type of research used is quantitative using a quasi-experimental method with a Non-Equivalent Control Group Design. The differentiated learning process with the PBL model is applied to the experimental class while the control class uses conventional learning methods. The sampling technique is purposive sampling. The research instrument uses observation sheets, questionnaires and objective test questions. Data analysis uses normality tests, homogeneity tests and hypothesis tests. Based on the questionnaire, the implementation of differentiated learning processes with the Problem Based Learning model in the experimental class is 98.01%. The statistical analysis test in this study uses Microsoft Excel. Based on the results of the hypothesis test, the t count value is 2.240 and the t table is 2.001. So t count ≥ t table shows that there is a difference in the average between the experimental class and the control class. This means that there is a difference in the average critical thinking ability of students in the differentiated learning process with the PBL model at SMP Negeri 1 Candung. Meanwhile, students' responses to teachers in the learning process received a positive response from students of 94%.

Abstract

This research is motivated by a learning process that only uses conventional models, so that in class it only focuses on the delivery of material by the teacher. Students are only asked to listen and take notes on the material presented, so that this has an impact on low student learning outcomes. This research aims to determine the effect of the Project Based learning model on the learning outcomes of the 8th grader at SMPN 1 Payakumbuh. This type of this research is quasi experiment using a non-equivalent control group design. This design begins with giving a pretest and ends with giving a posttest to the experimental and control groups. The sampling technique used was purposive sampling. Based on the results of the student response questionnaire to the Project Based learning model, a percentage of 86.45% was found to be in the very good category. Based on the results of hypothesis testing using the t test, a significance value of 3.685 > 2.0003 was obtained, meaning that there is a significant difference in the learning outcomes of students who use the Project Based Learning model and the learning outcomes of students who use conventional learning models. The results of the experimental class N-Gain test were found to be 0.55 in the medium category. It can be concluded that in this research, the Project Based Learning model has a significant influence on the learning outcomes of class VIII students at SMPN 1 Payakumbuh.
