Abstract
Mathematical understanding ability is the ability that students have to absorb and understand mathematical ideas. Mathematics is abstract ideas that contain symbols, so one must understand mathematical concepts before manipulating these symbols. So, the ability to understand mathematics is one of the initial abilities that students must have before increasing to other mathematical abilities. The purpose of this study is to find out the increase in mathematical understanding and to find out how much influence the model hasDiscovery Learning helpPhET Simulations. This type of research method used is quasi-experimental. The experimental method is used to determine the relationship between variables by involving the control class and the experimental class. The design used isthe nonequivalent pretest-posttest control group design. This design deliverspretest or tests carried out before being given treatment in the form of description questions in the control class and the experimental class. The experimental class was given treatmentTreatment in the form of learning with the methoddiscovery learning media-assistedPhET Simulations, while the control class received conventional learning with video and image media.Posttest or tests carried out after receiving treatment in the form of description questions that are the same aspretest to find out whether there is an increase in mathematical understanding abilities in the control class and the experimental class. From the results of the research that has been done, there is an increase in the mathematical understanding abilities of students who receive learning using modelsdiscovery learning media-assistedPhET Simulations better than students who get learning with a conventional approach. There is an influence of learning using modelsdiscovery learning media-assistedPhET Simulations on the mathematical understanding ability of elementary school students
