Use of Khan Academy in state schools in the Itapetininga/SP region and its correlation with assessment results

Abstract

With the recent introduction of some digital educational platforms in the São Paulo state public school system, many questions have arisen about the effectiveness and benefits of this action on student learning. An initial verification procedure that can be used in this case is to establish correlations between the data on the use of the platforms and the student's assessment results, which may provide some initial indications of the effect of use on learning. This article highlights Khan Academy, a free digital educational platform used in teaching mathematics. So, what is the correlation between the consistent use of Khan Academy and the results of mathematics assessments of state school students? To answer this research question, this article initially presents a discussion on the implementation model of Khan Academy throughout the second semester of 2023 in the state school system of São Paulo. In addition, it didactically presents Pearson's correlation coefficient, which was used in the statistical treatment of the data on the use of the platform by the students of the state schools of the Itapetininga Region Education Directorate. The research carried out is quantitative, with an exploratory view. Through the analysis of data from the consistent use of the platform by 44 students, a strong correlation was observed between the performance in the exercises carried out at Khan Academy and the performance evolution in the mathematics assessment applied to all state schools at the end of the bimesters, the "Prova Paulista".
