API analysis of the eAuthor 3 on the basis of graphical marking

The book explores the introduction of a novel graphical marking item type within the eAuthor computer-based testing system, allowing users to highlight specific areas in images. It details the analysis of the system's interfaces and the various marking methods available. A key focus is on the scoring process, which compares user markings to a solution marking based on two-dimensional intersection areas. The theoretical chapter delves into the calculations necessary for this scoring, providing a comprehensive understanding of the innovative assessment approach.
