Participants completed a pretest, a science lab safety training, a posttest (same as the pretest), a questionnaire with subjective presence questions, and a questionnaire with subjective cognitive load questions. Participants were again asked to complete a follow-up test (same as the pretest and posttest) a week later. <br/><br/>The results revealed three significant findings: <br/><br/>(a) Participants in the high and medium immersion conditions had significantly higher knowledge scores at posttest and follow-up than their peers in the low immersion condition,<br/><br/>(b) Participants in the high and medium immersion conditions reported higher presence scores than participants in the low immersion conditions.<br/><br/>(c) Correlation coefficients suggested that the higher the immersion and presence, the higher the knowledge scores are at posttest and follow-up.<br/><br/>In addition, multiple hierarchical linear regression models were conducted out of which one was significant.
