Description
We employed the eye-tracking method (Eyetracker by Tobii, 300 Hz) in order to observe
students’ strategies of choosing an option when they solved multiple-choice tasks focused on
graph slope interpretation. Each student solved 7 multiple-choice tasks focused on graphs in
kinematics. Most tasks were adopted from Beichner’s TUG-K test (Beichner, 1994).
Particularly, they were focused on position-time graphs and determining velocity from the
graphs as it is stated in the Objective 1 of the Beichner’s original test. Altogether 23 high
school students participated in the study (8 women, 15 men). Each stem-text, stem-graph and
each option was marked as a separate Area Of Interest for every task.We provide comparison
of attention allocation between two students group: those, who solved a test task correctly and
those who not. Based on the data analysis, we observed and described different students
understanding of the graph slope concept. Moreover, we applied the cluster analysis in order
to divide students into groups according to their attention spent on each option. We obtained
very similar results as in the previous case.
