The EFFECTIVENESS OF USING DESMOS GRAPH CALCULATOR APPLICATION IN FUNCTIONAL MATERIALS
Keywords:
Mathematics Applications, Learning Media, and FunctionsAbstract
Learning mathematics is considered difficult because of the continuity of concepts, abstract mathematics, and the lack of maximum learning media to become intermediaries in learning. The Desmos graphing calculator application is an application that can be downloaded on the Playstore for free and has a small memory load making it suitable for learning media on student smartphones. The material for the function of class X mathematics subjects must have sub-materials about function graphs. The purpose of the study was to determine the effectiveness of the Desmos graphing calculator application in the function of the MA Salafiyah Yapensa Jenggot. The research method uses quantitative methods with primary data sources from the results of the pretest and posttest instruments. Then the data analysis used the data normality test and the Wilcoxon Signed Rank Test. The results of the data analysis show that there are differences in values before using the Desmos graphing calculator application and after using the Desmos graphing calculator application. Then after being compared between the mean pretest and posttest, there is a significant difference between 53.39 and 81.57. Therefore, the Desmos graphing calculator application is effective as a learning medium.
