Teamwork Analysis of Playful Learning Students Groups on the Unispher™ Platform

An analysis of the educational performance of groups of students engaging in playful learning is considered. The goal of the analysis is to assess the teamwork of the group of students using grade dynamics. The grades are simulated as students' self-grades, grades within the group, and grades obtained under the efforts of teachers and mentors. The assessment is made based on the mean values of grades, the trend of grades, and the correlation of grade samples in a sliding window. The trend dynamics tracks changes in the mean grades of the group and the grades of its students. The correlation reflects the relationship between the mean grades of the group and the grades of each student in the group. The model has shown that the group grades level is lower than the self-grades, the correlations of group grades are higher and closer in values than the self-grades of students. This indicates the presence of teamwork. The efforts of teachers and mentors increase the level of grades and correlations, making them closer in values. The dynamics of trends and correlations indicate which students work as members of the team and which ones drop out. It was proposed that the assessment that combines these three assessments be used as a rating of educational performance and teamwork.
