<p class="16">Covid-19 spurs teachers to carry out online learning. This study aimed to analyze the improvement of students' critical thinking skills through online learning based on Android-based PhET Simulation. This research was Quasi-Experimental using one group pre-test and post-test design involving 27 students of class VIII who program science subjects at MTs Alif Laam Miim Surabaya, Indonesia. The research instrument used critical thinking skills tests that have met valid and reliable requirements. Before and after learning activities, students were given a pre-test and a post-test. The data collected was analyzed descriptively quantitatively. The results showed that there was an increase in students' critical thinking skills with an average N-gain of 0.57, in the medium category. The highest N-gain was achieved in the "interpretation" indicator, which is 0.83 in the high category and the lowest in the "analysis" indicator, which is 0.39 in the moderate category. This study concluded that learning science by using an Android-based PhET Simulation can improve the critical thinking skills of junior high school students.</p>

Abstract—This study aims to analyze students' scientific critical thinking skills through learning with edmodo-based blended learning models. This study is Pre-Experimental using one group pre-test post-test design involving 35 class VIII students at Public Junior High School 10 Jember, Indonesia. The instru-ments used were teacher activity observation sheets, student activity observation sheets, scientific critical thinking skills assessment sheets, and student motivation sheets. Before and after learning activity, students are given the same initial test (pre-test) and final test (post-test). The collected data was analyzed by quantitative descriptive analysis. The results of the study show that: (1) students are motivated in classical learning by 78.13% with motivated criteria. The highest value is on the likes and active indicators using Edmodo, which is equal to 88.47% and the lowest value on the indicator of activity asks questions and opinions at edmodo, which is equal to 70.93%; and (2) there is an increase in scientific critical thinking skills of students with a mean n-gain of .32, with the criteria being moderate. The highest value is achieved on the indicator of fact analysis, which is equal to .55 and the lowest value on the indicators of delivery of argumentation, which is equal to .19. The conclusion of this study is that science learning with an edmodo-based blended learning model can motivate learning and improve scientific critical thinking skills of junior high school students.

This research is motivated by the low ability of students to think critically. The purpose of the study was to determine the effect of the Controversial Issues (CI) learning model in improving students' critical thinking skills. This study uses a quantitative approach with a quasi-experimental method. The study design used Nonequivalent [Pre-Test and Post-Test] Control Groups Design (NCGD). The research samples were fourth grade students of SDN 4 Metro Timur, SDN 5 Metro Timur, SDN 8 Metro Timur, and SDN 10 Metro Timur, 60 students were used as the experimental class and 60 students were used as the control class. Data collection tools in the form of sheets about students' critical thinking skills. Data collection techniques in the form of tests, namely pretest to measure the initial ability of students' critical thinking skills and posttest to see the final ability. Based on the results of the study concluded that the effectiveness of the use of the Controversial Issues learning model affects the critical thinking skills of class IV elementary school students, so that students' critical thinking skills in the experimental class are much better when compared to the control class that has conventional learning.

This study aims to analyze the critical thinking skills of junior high school students on Pythagoras material. Subjects in this study are students of class VIII-F in SMP Negeri 1 Ngamprah with the number of students 37 people. The method used in this research is qualitative descriptive. This type is chosen because it aims to describe the skills of students in solving problems of mathematical critical thinking independently. The research phase is divided into three, namely planning, implementation, and reporting. The technique of collecting data in the form of test. Data analysis techniques based on indicators of mathematical critical thinking skills that has been determined by researchers include: (1) identifying the concepts used in problem solving, (2) formulating an action (strategy, tactics, or approach) in solving problems, (3) providing arguments or reasons for answering and solving problems, and (4) evaluating evidence or decisions taken in solving the problem. The results obtained quantitatively show that the level of mathematical critical thinking skills of students in SMP Negeri 1 Ngamprah in solving the problems on Pythagoras material still falls into the low category. The evidence from the percentage of each indicator with the highest rate of only 61%. Some factors influence the level of students critical thinking skills, including the preparation of incomplete and appropriate strategies, provide arguments without showing the truth, and the students' accuracy in working on the questions.

Critical thinking is one of the 21st Century skills involved in education and is required of students nowadays. The study investigated the critical thinking skills of Junior high school students from three selected public schools in Region 3, Luzon, Philippines.  Infusion of the critical thinking in Chemistry through selected teaching strategies of inquiry-based, problem solving, collaborative, and lecture methods. CEU-Lopez Critical Thinking Skills Test (2012) with a reliability test value of 0.87 was used to measure the students’ critical thinking skill levels. Triangulation of inquiry-based teaching, problem solving, and collaborative teaching methods was used as an intervention to determine the enhancement of the respondents’ critical thinking skills and academic performance. Gathered data were processed statistically through descriptive and inferential tests.  Results revealed that there is a significant difference in the critical thinking skill levels of Junior high school students in Chemistry. The critical thinking skill levels of the student respondents were highly comparable with respect on their academic performance in Chemistry.  The students demonstrated good knowledge, attitude and performance in Chemistry after the infusion of the critical thinking approach in the intervention. The different teaching strategies utilized in the research were applicable in the enhancement of the critical thinking skills of the Junior high school students in Chemistry.

Thinking Ability

The ability to think critically is one of the highest levels of ability. Developing critical thinking skills in students is still considered important to be improved in schools so that students are able and accustomed to facing various problems around it. This study aims to analyze the critical thinking skills of junior high school students who are in excellent classes and regular classes. This research was conducted in Bandung Barat. In this study students are given a test in the form of questions with critical thinking skills, the problem is used to compare between the superior class and ordinary class. Assessment of the problem using several factors of critical ability include 1) students can not understand the problem correctly, 2) students rush in doing the problem, 3) the students cannot choose the problem-solving strategy correctly and 4) the students work on the problem systematically. Then the matter of critical thinking skills of mathematics is analyzed using quasi-experimental research method to analyze students' critical thinking ability that influence learning result. This study shows the differences in critical thinking ability of junior high school students who are in excellent class and ordinary class. This study shows that superior classes are better in mathematical critical thinking ability than a regular class. The results of this study can add knowledge about critical thinking mathematics junior high school students who are in the class and ordinary class and used to facilitate for educational practitioners in the development of critical mathematical thinking skills.
