We employed the eye-tracking method in order to observe students' strategies of choosing an option when they solved multiple-choice tasks focused on graph slope in kinematics. 32 high school students participated in the study. We provide comparison of attention allocation between two students group: those, who solved a test task correctly and those who did not.
Correctly answering students paid more attention to all correct options than incorrectly answering students. And vice versa.
Incorrectly answering students mostly paid the most attention to options which show typical identified misconceptions in graph (slope) interpretation.
