<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>

Computer-supported collaborative learning (CSCL) provides an environment that enhances social interaction and shared knowledge construction among students. However, limited research has examined CSCL reinforced by question-asking scripting activity. This research investigated the effects of CSCL with question-asking scripting activity on the development of conceptual understanding and critical thinking in science. Moreover, the research design was a three-group pre-test-post-test quasi-experimental study in which the research sample were 106 Grade 7 students. The only difference between the control and the experimental groups was the exposure to CSCL. The experimental groups were exposed to CSCL approaches: one without scripting while one was exposed with question-asking scripting activity. Results revealed that CSCL approaches significantly affected the development of students’ conceptual understanding and critical thinking. Specifically, CSCL with scripting stimulated more intellectual discussion which allowed learners to deepen lesson comprehension and improve their critical thinking skills. Insights on the innovations through technology integration, collaborative inquiry learning, and question-asking activity to enhance science education were also discussed. The findings of this study have important implications for future practice.

The study aims to develop critical thinking skills among prospective teachers. The study was experimental in nature; quasi experimental approach was used to conduct the study. The population of the study was prospective teachers studying at master level. Sample of the study was 73 prospective teachers enrolled in the educational research course in two groups. The first was labeled as the control group, while one was labeled as the experimental group. To assess the critical thinking skills of prospective teachers test was developed by the research using guidelines of Watson and Glaser test. Test was consisted of five dimensions i.e. analyzing, assumptions, deduction, and inference and interpreting information. Cronbach's alpha determined the test's reliability to be 0.80. Intervention was consisted of 10 lessons related to educational research course. The prospective teachers performed well in analyzing, Assumptions, deduction and overall CTS in post-test as compare to pre-test. There was statistically noteworthy the variation between the or before as well as post-test grades of Inference and interpreting. The critical thinking skills are essential element to compete 21st century challenges. Prospective teachers have to face many educational challenges to improve students learning, it is necessary that they should be prepared with CTS either to infuse through separate curriculum or embed with existing curriculum.

The background of the problem in this study originated from students' mathematical critical thinking skills that are still low. One way to overcome these problems is to use Jigsaw cooperative learning. This study aims to determine the effect of the use of jigsaw cooperative learning on the ability to think critically mathematically elementary school students. The method used in this study is a quasi-experimental method with nonequivalent groups pretest-posttets design. The subject of this research is the fifth grade students of SD Negeri Andir Kidul 1, Bandung Municipality. The instrument used was a test item to measure students' mathematical critical thinking skills. Based on the results of data analysis using the t test at a significance level of 0.05, from the t test results obtained 0.192 results. So it can be concluded that Jigsaw cooperative learning has a significant influence on students' mathematical critical thinking skills.
