We measured the success of our predictions using 10-fold cross validation, root mean square deviation, and mean absolute error. Over different sample sizes and different numbers of tags, we achieved prediction accuracy ranging betwe河潭 发表于 2025-3-30 12:29:46

Further analyses reveal an increase in diagram fixation duration when the text was judged as being less relevant, but when compared to instances where the text and diagrams were both seen as only somewindemnify 发表于 2025-3-30 19:15:58
Johannes Müller,Joseph Kraußworked with two virtual labs. Students reported processes that are typical to PS-I and, out of these, prior knowledge activation was associated with constructing more complete models. Based on this, we suggest ways to support students in learning from their inquiry.避开 发表于 2025-3-31 00:28:40
Johannes Müller,Joseph Kraußst, fear, and sadness were comparatively rare. The emotions varied as a function of instructional scaffolds and were systematically linked to different student behaviors (idling, constructing code, running code). Boredom, flow/engaged, and confusion were also correlated with performance outcomes. ImDysplasia 发表于 2025-3-31 04:18:33

Studies of online learning in higher education found that when students struggle with recorded video lecture content, questions and confusion often remain unreported and thus unsupported by instructors.

Johannes Müller,Joseph Krauß. We compared the system with TF-IDF and Universal Sentence Encoder. Our results showed that fine-tuning on the course data and returning the top 3 and 5 answers improved the accuracy results.
