Abstract

However, students had to study using self-access. This could have a negative impact on study results. On the other hand, they could retain their academic results due to the extension of the time needed to grasp the subject matter. This article deals with the analysis of the performance of students regarding the study grades and the time required to complete a single assignment in the course of Mechanical Testing and Defectoscopy of Materials.
