In learning mathematics, students are still found to have difficulty in understanding and developing critical thinking skills. Therefore, the purpose of this study is to determine the significant influence of the Problem Based Learning model assisted by concrete media on the ability to think critically mathematics in grade IV in elementary school. This research was a quasi-experimental study with a non-equivalent control group design. The population of class IV SD as many as 293 people. The sample was determined by cluster random sampling technique. The sample in the experimental group was 32 students and the control group was 30 students. Data used as a test method in the form of a subjective test (description). The data obtained were analyzed using the t-test analysis technique with the polled variance formula. The results of data analysis were obtained (t-count = 4.021> t-table = 2,000) at the significance level of 5% (dk = 32 + 30 - 2 = 67) which means that there was a significant difference in the ability to think critically mathematics between groups being taught with the model of Problem Based Learning with media aids Concretely with the group learned using conventional learning models in class IV elementary school. It can be concluded that the Problem Based Learning model assisted by concrete media influences the ability to think critically mathematics in class IV. The results of this study can be used as input for teachers to choose various learning models in teaching.

Implementation of learning in class 11th MAN 1 and MAN 2 Banda Aceh City Students only get information without going through discussion activities, students who are not brave enough to express ideas or ideas, so that students are not trained in using their critical thinking skills. This study aims to determine the improvement of students' critical thinking skills through the application of the STEM-based discovery learning model to the motion system concept. The research approach used is quantitative with the type of pre-experimental research. The research design used is the one-group pretest-postest design. The population was all of 11th grade students, amounting to 292 people. The sampling technique used was a total sampling. The sample in this study consisted of 292 students. The instruments in this research were pretest and posttest multiple choice questions with reasoned. Data analysis consisted of normality test, paired sample t-test at a significant level of 0.05 and n-gain. The results of the paired sample t-test obtained tcount 48 and value (ρ.001), so it was concluded that there were differences in critical thinking skills and learning outcomes of students before and after learning with the application of the STEM-based discovery learning model to the motion system concept. The results of the n-gain test using the Meltzer formula showed that the gain in critical thinking skills was 0.85, so there was an increase in critical thinking skills with a high category.

This study aims to analyze the effectiveness of science e-modules for class VII junior high schools based on socioscientific issues to improve students' critical thinking skills. The type of research used is Pre-Experimental with one group pretest-posttest design. This research was conducted at SMP Negeri 2 Seririt in class VII A with a total of 30 students. Data were collected with 12 items of critical thinking skills test on global warming material through pretest and posttest. Data were analyzed using Paired Sample T-Test and gain score test. The Paired Sample T-Test was used to calculate the significance of increasing students' critical thinking skills, but the gain scores were used to calculate the increase in students' critical thinking skills. The results of this research showed that there was a significant difference in students’ critical thinking skills before and after used science e-module in learning (sig. < 0.05). The normalized N-gain test also showed an increase in students' critical thinking skills with a value of 0.55 in the medium category. Based on the results of the Paired Sample T-test and the normalized gain score, it can be concluded that the e-module based on socioscientific issues is effectively used to improve students' critical thinking skills.
