The Effect of Problem Based Learning Model with the Assistance of Wordwall Media on Collaboration and Critical Thinking Skills in Science in Elementary School Students

<h4>Abstract :</h4> <p>The problems that occur at Pasrujambe 01 State Elementary School in learning Natural and Social Sciences (IPAS) are suboptimal collaboration skills, low critical thinking skills, teachers being the center of learning, teaching materials only using textbooks, and the use of less innovative learning models and media. Therefore, this study aims to examine the effect of the PBL model with the help of <em>Wordwall media </em>on collaboration skills and critical thinking abilities of elementary school students. This type of research is quasi- <em>experimental research </em>using a <em>Pretest Posttest Control Group Design. </em>The data analysis method used the T-test or <em>Independent sample T-Test. </em>The results of the experimental class data analysis for collaboration skills and critical thinking skills showed higher values than the values in the control class. This is reinforced by the calculation of the hypothesis test which states that the results of students’ collaboration skills obtained a significance value ( <em>sig 2-tailed </em>) of 0.001 and collaboration skills obtained a significance value ( <em>sig 2-Tailed </em>) of 0.000 so that both are less than 0.05. This proves that there is a difference between the control class and the experimental class regarding collaboration skills and critical thinking skills. Thus, it can be concluded that the PBL model with Wordwall media has a significant influence on collaboration and critical thinking skills.</p>
