 This study aimed to develop a methodology for training teachers to evaluate electronic tools for young learners and to assess its effectiveness experimentally. A module on expert evaluation of the quality of e-tools for young learners was developed for teacher trainees. The weights assigned to various criteria were determined based on expert evaluations. Educational principles, correlation between e-tool content and the curriculum, interactivity, multimedia, assistance systems, and ergonomic requirements were discussed. Based on the criterion ranking, the significance of each criterion was calculated. Non-parametric statistical methods such as Pearson's Cheat Square were used to calculate the significance of the results. The conclusion was that expert evaluation of e-tools for young learners is a complex process that progressively becomes more commonplace. This article was authored by Nadia V. Olifarenko, Alona I.
