<![CDATA[This study aims to describe the effect of quantum teaching model-based teaching materials on critical thinking skills of elementary school students. This type of research is development research using a model developed by Borg and Gall. Teaching Material Development starts from the preliminary study phase, planning, product design, product design validation, product trial and final product. The research instruments used consisted of validation sheets, sheets, questionnaires for analyzing student needs, cognitive tests, and tests of critical thinking skills. The research subjects were students in Class V of SDN 1 Cengal, SDN 2 Cengal and SDN 3 Cengal, Japara District, Kuningan Regency. The results showed that there was an increase in students' critical thinking skills using quantum teaching model-based teaching materials compared to students using conventional learning. The difference in this increase can be seen in the results of the gain test of students' critical thinking abilities in the experimental class showing N-gain of 0.59. Then the N-gain in the experimental class is included in the criteria of being. While the results of the test gain students' critical thinking skills in the control class obtained N-gain of 0.20. Then the N-gain in the control class is included in the low criteria]]>
