Abstract
This study was an experimental research conducted on one experimental group and one control group (conventional), which aimed to improve students' critical thinking skills of class IX at SMP Negeri 8 Makassar. The study was conducted in two stages. The first stage was the preparatory phase of the research. It is to develop the Problem Based Instruction (PBI) model, by making the lesson plans, student books, and test of critical thinking learning. The second stage is research implementation. It determines the sample of the research, performs the initial test, implements the learning process with PBI model, and performs the final test. The subjects of the study are the students of SMP Negeri 8 Makassar taken by using random sampling techniques. The research design is Quasi-Experimental Design, designed as Non-equivalent Control Group Design. The results showed that in the descriptive analysis, the general test of critical thinking skills of learners in the experimental class is in the very high category. Meanwhile, in the control class, it is only in the high category. Thus the critical thinking skills of learners who are taught through the PBI model are superior to those conventionally taught. Similarly, through inferential statistical analysis (t-test), it is found significant differences in the level of critical thinking skills of learners in the experimental class and control class. It can be concluded that there is a positive influence of PBI model on the level of students’ critical thinking skills in class IX at SMP Negeri 8 Makassar.
