Penerapan RealQu pada Sistem Bilangan Real dalam Pembelajaran di Masa Pandemi Covid-19

The purpose of this study was to analyze the application of the RealQu, which is a mobile learning media that contains real number system material that will support online lectures during the Covid-19 pandemic. The research method used is descriptive analysis. The research subjects were 20 students who had taken the real analysis. The data collection technique was carried out by analyzing student answers and conducting interviews with the interview guidelines. The results showed that students were more assisted and facilitated by the RealQu learning media which contained the real number system theorems. This is indicated by an increase in the value and results of the analysis by the stages of solving the questions which also increased after the use of RealQu. During the interview, students also stated that Realqu helped them remember all the theorems and how they were used in problem-solving.
