Daftar Isi:
- Based on interview with biology teacher in SMP N 22 Bandar Lampung, studentâ€TMs critical thinking skill were not optimally developed. Alternative that can be used to improve studentâ€TMs critical thinking is problem based learning (PBL) model. This experiment aims to find out the influence of PBLmodel towards improvement of studentâ€TMs critical thinking skill. This is quasi experiment using pretest posttest group non equivalent design. Sample are students from VIIIA and VIII B which selected from population by random sampling method. Quantitative data from the average of pretest, posttest and N-gain which statistically analyzed with Mann Whitney-U test. Qualitative data are studentâ€TMs critical thinking skilldescription, learning activities and studentâ€TMs response about applicating PBL model which descriptively analyzed. Result of this experiment showed that studentâ€TMs critical thinking skill improved significantly in giving reason (18,34%) and giving solution (44,36%)whereas not in formulating problem, hypothesize and interpretating statement.The studentâ€TMs learning activities in all observed aspects (78,49%). Studentâ€TMs learning activities improved in asking question (6,4%)and presenting group discussion result (16,45%) which are at high level. The students (86,25%) also give positive response in PBL.  Keywords: problem based learning model, critical thinking skill, human digestive system
