This work was motivated by the idea of approaching teaching practice in multilevel classes based on a problem, namely the need to improve the management of time in these types of classes. The time management strategy, developed in this work, consists of applying two modes of alternating teaching, the classical mode "work and make work" and the "actual - virtual" presence of the teacher mode using the software Netsupport School. The study focuses on the impact of the application of this software solution in two heterogeneous lessons of the French language, specifically of oral activity, for a subgroup of a double-level class (2nd Primary Year + 3rd Primary Year). The obtained results are conclusive since this approach has made it possible to lower the dead time from 13 min to 9 min, to reduce the teacher's great effort from 30 min to 26 min and to considerably increase the total duration of the task of the learners from 26 min to 46 min.
