However, much of the existing research has predominately focused on understanding inter-individual differences in students' emotions, overlooking the dynamic intra-individual processes that unfold over time. The present study aims to examine differences in inter- and intra-individual relationships of two learning emotions (<em>enjoyment, boredom</em>) and three facets of learning outcomes: <em>concentration</em> as a cognitive aspect of the learning process, <em>learning time</em> as a behavioral aspect, and <em>learning satisfaction</em> as an evaluative aspect. We collected weekly data of 119 vocational students over 14 weeks and used multilevel linear mixed effect models. Results revealed that inter-individual enjoyment positively predicted the three learning outcomes, while intra-individual enjoyment positively predicted concentration and learning time. Inter-individual boredom negatively predicted learning satisfaction, while intra-individual boredom was not a significant predictor. These results highlight the importance of enjoyment for the learning process and point to the more unclear role of boredom. Also, the findings emphasize the importance of differentiating between inter- and intra-individual relations.</div></div><div><h3>Educational relevance statement</h3><div>The present study highlights the crucial role of emotions, specifically enjoyment and boredom, in learning.

We found that search term generation, even controlling for sites accessed, was the dominant predictor of learning (i.e., knowledge gain and critical questioning). We argue these navigation behaviors reflect cognitive flexibility and task-centered navigation. Mediation analysis revealed that metacognitive awareness was a driving predictor behind students' successful implementation of these behaviors.
