%T The Influence of the Problem-Based Learning Model Assisted by the  Firing Line on Critical Thinking Skills in the Science Subject of 4th  Grade Elementary School Students
%U http://repository.uhamka.ac.id/id/eprint/42554/
%X The research at this time aims to analyze the ability of each student in the  type of critical thinking by using a problem-based learning model supported  by the firing line. The research method used is a quantitative research  approach with a pretest-posttest research design of a non-equivalent control  group design. 31 students are declared as the experimental class while 31  students who will be the control class will be randomly selected. This study  used an instrument containing 12 essay questions. The final result of this  study shows the paired-sample t-test analysis that the significance value  (two-tailed) is 0.000, which is less than 0.05. In addition, the N-gain test  displays the average of the N-gain for the experimental class which is 0.7490  can be categorized as "high", and for the control class N-gain which is 0.6522  can be categorized as "medium". Therefore, the conclusion from the  explanation above is that there is an increase in students' critical thinking  skills, namely the acceptance of the hypothesis when applying a problemsolving-  based learning model with the help of the firing line in IPAS learning  for grade 4th elementary school students, in other words, the hypothesis is  accepted.
