Abstract


The purpose of this study is to determine the application of the Project Based Learning model effectively with the completeness criteria achieved, there is an effect of confidence and activity, and there is an average difference. This research is a type of quantitative research with experimental methods. The independent variable in this study is active and confident, while the dependent variable of research is students' critical thinking skills. The sampling technique used purposive sampling, with samples of classes VIII A, VIII B and VIII C. Data collection methods in this study were interviews, observations, questionnaires, evaluation tests.The results showed that students' critical thinking ability using the Project Based Learning model achieved completeness both individually and classical. The average student's critical thinking ability
reaches 85.26. The percentage of completeness is 94% or as many as 29 students from 31 students have reached the completeness of the ability to think critically. The influence of confidence and activity on the ability to think critically by using Project Based Learning model of 97.7%. There are differences in the average ability to think critically between classes that apply the Project Based Learning model to the class that applies conventional learning models. The average value of the critical thinking ability of the experimental class is 85.26 and the control class is 74.19. It is expected that the teacher can make the Project Based Learning model as an alternative to learning mathematics that can improve self-confidence, activity, and critical thinking of students in other material
