Critical thinking is the ability to think rationally and reflectively about what must be done or believed. This skill allows one to make logical decisions based on information obtained and processed according to ability. The development of critical thinking skills in learning is essential because they enable students to deal effectively with social, scientific, and practical problems. Therefore, this research aimed to describe the effectivity of problem-based learning to improve students’ critical thinking skills to deal with hoax information in chemistry. This research was carried out through the control and experimental groups. Data were collected from 60 the 11th-grade students of the State High School in Lampung Province, Indonesia, and analyzed by using SPSS version 23.0. The effectivity of problem-based learning was measured based on the n-gain. The n-gain value of experimental and control classes was 0.709 (high) and 0.322 (medium), respectively. The results indicated that problem-based learning has facilitated and effective to improve students’ critical thinking skills.

The current study explores the effects of applying the Problem-Based Learning (PBL) Strategy on the 11th-grade scientific stream Jordanian students' acquisition of the concepts of developing their critical thinking skills. This study's significance lies in its emphasis on the worldwide growing tendency to apply PBL teaching strategies that consider developing the students' mental capabilities and creative thinking skills and, consequently, help them solve status-de- facto educational problems face and solve problems in their lives. The researchers used the experimental method in their study, which is based on studying the relationship between the independent and the dependent variables. For this reason, three study student groups, equal in their age, intelligence, academic achievement, social and economic standing, were selected. Two experimental groups were exposed to the independent variable (PBL) method, whereas the third control group was not exposed to the independent variable. Instead, it was taught in the Motion Unit in Physics by using the traditional teaching method. The results of the study were analyzed statistically, applying for the SPSS program. The Arithmetic Mean, the Standard Deviation, the Torsional Modulus, and the T-Test were used for the study analysis. The study results revealed that the two (PBL) experimental groups have proved to be much more superior to the control group's third traditional teaching method.

Pbl Model

This study aims to determine the effectiveness of the Problem Based Learning (PBL) model on the critical thinking skills of 7th-grade students of SMP Negeri 34 Bandarlampung (Public Senior High School 34 Bandarlampung). This quasi-experiment involved 2 groups of students, totaling 28 students for the Experimental class and 26 students for the Control class. Data collection was obtained by using an essay test instrument which was presented in the pretest and posttest. Based on the research results, it is known that the posttest results of the experimental class are 78.82, and the results of the control class are 74.07. The data were then analyzed by independent sample t-test and obtained tcount (2.213) greater than ttable (2.007). The effectiveness of the Problem Based Learning (PBL) model was tested with the effect size test, the results showed a number of 0.2 with a low category. So, it can be concluded that the Problem Based Learning (PBL) model has an effect on increasing students’ critical thinking skills but with low effectiveness.

This study aims to determine the effect of the problem-based learning model (PBL) with a scientific approach to critical thinking skills of class X students of Al-Ma’arif Pandan Indah Islamic High School 2016/2017 academic year. The type of research used is quasi-experiment with Nonequivalent control group design. The population in this study were all students of class X Islamic High School Al-Ma’arif Pandan. The sample used consisted of two classes taken using nonprobability sampling techniques, namely class XA as the experimental class, and class XB as the control class. The technique of collecting data on the implementation of RPP using the observation sheet and critical thinking skills of students was measured using a test in the form of a description question that had been validated by 2 expert experts. Data analysis of critical thinking skills carried out by t-test found that t-count = 2.58> 2.042. Based on the results of the analysis it can be concluded that the problem-based learning model with a scientific approach significantly influences students' critical thinking skills.

KERANGKA KONSEPTUAL MODEL CONCEPTUAL PROBLEM BASED LEARNING UNTUK MELATIHKAN KEMAMPUAN BERPIKIR KRITIS SISWA SEKOLAH MENENGAHAbstractLearning to facilitate critical thinking requires a set of specific learning models that aims to trains critical thinking skills that in this study is the development of conceptual problem based learning model. This study aims to develop a conceptual problem-based learning model to facilitate high school students’ critical thinking skills. This study is a development research that will produce a model of learning products, namely a valid Conceptual Problem Based Learning Model to facilitate high school students’ critical thinking skills. Validation of CPBL learning model includes two components namely content validity and construct validity. The result of data analysis shows that the CPBL model can be declared valid with reliability percentage of 97% (reliable) based on syntax model assessment that is: 1) prior knowledge; 2) organize; 3) investigate; 4) analyze; 5) evaluate; to facilitate critical thinking skills.AbstrakPembelajaran untuk melatihkan berpikir kritis memerlukan satu set model pembelajaran yang spesifik melatihkan kemampuan berpikir kritis yang dalam penelitian ini pengembangan model conceptual problem based learning.
