Interpretation of physics graphs by experts and novices followed by the eye-tracker
 Vondráčková, Terézia ; Kekule, Martina (advisor) ; Mandíková, Dana (referee)
This thesis is focused on identifying key aspects of mechanics graphs regarded by students and experts. It also contains observations of student's attention focused on each graph. This data was collected using eye tracking camera. 23 high school students and 14 experts participated in this research. Our group of experts contained graduate and post-graduate students as well as researchers from faculty of Mathematics and Physics at Charles University. Our results suggest that experts were able to memorize more information from each graph than high school students. Difference in focus on relevant parts of graphs was obvious from analyzing correct and incorrect answers of high school students and they consider axes and their labeling as the key parts of graphs in contrast to the students. Incorrectly answering students were more focused on parts with no relevance to the task in question. On the contrary, students with correct answers spent less time looking on non-relevant parts of graphs. Ideas of incorrectly answering students were mostly focused on wrong idea about graph as a sketch of real situation, or picture resembling physical situation.

High school students' interpretation of a graph from mechanics observed by the eye-tracking method
 Vondráčková, Terézia ; Kekule, Martina (advisor) ; Snětinová, Marie (referee)
This bachelor thesis deals with the solution of tasks monitored by the eye-tracker. We were examining high school students who solved 6 tasks focused on the interpretation of a graph in mechanics. They were monitored by the eye-tracker during their solving of the tasks. Based on their recorder eyes' position we can figure out their strategies of solution. We identified several typical misconceptions when working with graphs and typical students' approaches to the graph interpretation. Information about this topic can be useful, for example, to teachers for their future teaching.
