The aim of this study was to determine the visual measurement results related to the behavior/processes of solving skill-based science questions of eighth grade students by eye tracking technique. Non-experimental quantitative research method was used in the research and visual measurement results were supported by heat maps and eye splash movements. Nine questions, with difficulty and discrimination indexes calculated, were applied to 56 eighth grade students. Data were collected with a skill-based test, eye tracking device, think-aloud protocols and a perception scale towards next generation science questions. The data obtained from the eye tracking device was examined using Gaze Viewer software and the results were shown as images. The results revealed that visual measurement results differed according to gender and 2023 high schools entrance exam scores. Additionally, negative relationships were found between visual measurement results and students' practice test scores and their perceptions towards solving next generation science questions. It was determined that average duration of fixation had a significant predictive effect on students' self-efficacy levels for solving next generation science questions.
