Immersive videos for training pre-service teachers (PST) are becoming increasingly important and, yet, inadequately investigated. This article focuses on the role of presence as a possible aid in 360 videos for future educators, presenting the results of a study involving 118 PSTs. A multiple factor analysis of the "eXtended Reality Presence Scale" was used to understand possible subfactors covering this construct and the potential role of one's content area and major in influencing PSTs' viewing experiences. Additionally, written noticings from 360 videos were collected for exploring correlations between themes noticed and degrees of presence. There were three main results: 1) three subfactors -- i.e., Emotional Connectivity, Co-Presence, and Awareness of Self -- composed the feeling of presence, 2) the PSTs' major had an observable relationship with experiencing co-presence, and 3) presence was positively correlated to a better focus on students and negatively correlated to content knowledge in participants' noticing.
