In this paper we present an eye tracking study aimed at examining learners' behaviors while searching for the right answer in multiple-choice tests. In particular, the analysis is focused on a geometry problem characterized by four graphical solutions. The data gathered through several experiments have allowed us to find interesting relationships between answers and testers' performance (especially with regard to time spent watching the available options and gaze wavering between the two most plausible choices), as well as to identify otherwise hidden similarities among testers themselves. Providing a better understanding of students' learning processes, the obtained results can potentially be exploited to improve the design of assessment tasks and to train intelligent tutoring systems.

In this article we present an eye tracking investigation aimed at inspecting the eye behaviour of users while looking at the home page of online newspapers containing ad banners, especially during the first seconds of exposure. In particular, we consider different positions and combinations for banners placed in the masthead region of the page, to verify whether there are solutions that are better than others in catching the early attention of the user. The study involved 50 testers and was carried out on simulated newspaper home pages using a remote eye tracker. Although differences in testers' behaviours were not always statistically significant, some interesting divergences could however be identified, which can be the starting point for more focused studies on the subject.
