Abstract

The aim of this study is to determine whether there is an effect or not the implementation of the Project Based Learning (PjBL) learning model on critical thinking skills in the spatial structure subject at VIIIth class students of MTs Citra Abdi Negoro in 2024/2025 Academic Year. The type of research is a quasi-experimental study with a two-group pre-test and post-test research design. The population are all VIIIth class students consisting of 3 classes. The research sample are 2 classes (VIII-1 and VIII-2 class). VIIIth-1 class as an experimental class using the Project Based Learning (PjBL) learning model and in VIIIth-2 class as a control class with a conventional learning model. The average pre-test score in the experimental class (54.93) while the average score in the control class (53.80). After completing the learning, a post-test was obtained with an average result of the experimental class (75.80) and the control class (63.17). The t-test results obtained = 3.083 > = 2.002, means it is accepted and there is a positive and significant influence in the application of the Project Based Learning (PjBL) learning model on Critical Thinking Skills Assisted by Interactive Videos at VIIIth class students of MTs Citra Abdi Negoro in 2024/2025 Academic Year.
