The Problem-Based Learning with Argumentation (PBLA) model is a development model of Problem-Based Learning (PBL) added to the Toulmin Argumentation activity to increase the critical thinking skill in junior high school. The research aims to determine the feasibility of PBLA in terms of its validity and effectiveness. The research samples are two groups of students (class 1 and class 2) with 26 students in each class. Before learning to use PBLA, each class was given a pretest, and after learning to use PBLA were also given a posttest. PBLA validity data were obtained through validity sheets and analyzed through expert agreement. PBLA effectiveness data was obtained through critical thinking skill tests and analyzed by paired t-test, n-gain, and two-average similarity test. The results showed that the content validity and the construct validity categorized as valid with a score of 3.5 and 3.3. The reliability scores obtained are 77.10% and 77.67%. The critical thinking skill data showed a significant increase in critical thinking skill at α = 5%, the average n-gain was categorized high, and there was a similarity in increasing critical thinking skills for the two classes. In conclusion, PBLA is effective in increasing critical thinking skills for junior high school students

Pbl Model

This study aims to determine the effectiveness of the Problem Based Learning (PBL) model on the critical thinking skills of 7th-grade students of SMP Negeri 34 Bandarlampung (Public Senior High School 34 Bandarlampung). This quasi-experiment involved 2 groups of students, totaling 28 students for the Experimental class and 26 students for the Control class. Data collection was obtained by using an essay test instrument which was presented in the pretest and posttest. Based on the research results, it is known that the posttest results of the experimental class are 78.82, and the results of the control class are 74.07. The data were then analyzed by independent sample t-test and obtained tcount (2.213) greater than ttable (2.007). The effectiveness of the Problem Based Learning (PBL) model was tested with the effect size test, the results showed a number of 0.2 with a low category. So, it can be concluded that the Problem Based Learning (PBL) model has an effect on increasing students’ critical thinking skills but with low effectiveness.
