Therefore, education has a pertinent role in preparing qualified human resources. In line with this, the teaching of biology has a potential to empower these HOTs, one of which is critical thinking skill. The purpose of this study was to determine the differences of students’ critical thinking skill between students who were taught by using Think Pair Share (TPS) model and Problem Based Learning (PBL) models. The quasi-experimental study using pretest-posttest design non-equivalent control group design was employed in this study. The control group was taught by using TPS while the experimental group was taught by using PBL model. 51 students of the eleventh grade of senior high schools in Banjarmasin were involved. The data were collected from the essay tests. Meanwhile, in regard to the critical thinking skill assessment, it referred to [1]. Then, the data were analyzed through ANACOVA with SPSS 17.0 program. The results of this study showed significant information on the results of a pretest to posttest scores for the critical thinking skills of 0.004 <0.05. These results pointed out that the students who were taught by using PBL have better critical thinking skill than those who were taught by using TPS.
