Online video lectures have been promoted by technological advances as a beneficial tool for learning scientific experiments and were proved valuable in the COVID-19 pandemic numerous times when millions of students were forced to be home-schooled. Therefore, the urgency of studying the effects and various factors influencing online scientific experiment teaching is highlighted to enhance students’ learning outcomes. This research aims to explore how online video lectures influence procedural and declarative knowledge and to determine whether instructor presence and other visual elements have specific effects on students’ learning. In this study, seventy-eight students were randomly assigned to two groups for the controlled experiment. Students’ eye movement data were collected to analyze visual attention distributions. Data analysis shows that (1) online video lectures significantly impact the retention of knowledge but have little effect on knowledge transfer; (2) instructor presence has no significant effect on students’ learning performance; and (3) complex visual elements such as instructor appearance, tags, and dynamic images compete for students’ exogenous attention and significantly affect learning. These findings uncover various factors influencing learning in online video lectures and suggest solutions for proper video design to facilitate students’ learning.
