Abstract
The Problem Based Learning Model (PBL) is a learning model that is highly recommended in the implementation of the National Curriculum. This research is to obtain an overview of the implementation of PBL in learning environmental pollution in an effort to improve critical thinking skills and mastery of concepts. This research was carried out by the quasi-experimental method, namely the pretes-postes control design. The study subjects were 73 students who were divided into control groups and experimental groups. The data obtained comes from the completion of the critical thinking test problem in the form of a description and mastery of the concept in the form of multiple choices. The results of the study explain that the acquisition of critical thinking skills with higher value PBL learning ( average - = 82.1) compared with conventional learning ( average - =61.4 ) with a calculated t value of 28.34 (p 0.05). Mastery of concepts with PBL learning gets a higher score ( average - average = 76) compared to conventional learning ( average - 0.05TAG. The results showed that the PBL learning model was able to improve critical thinking and mastery of the concept of students in class X environmental pollution material at Senior High School 1 Dramaga.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
