Abstract

fetched live from OpenAlex

ABSTRACT Students' perceptions about the use of online learning tools have been shown to vary among studies. Their perceptions may have a profound impact on performance in the course and subsequent behavior toward continued use. This article presents a theoretical framework to identify three dimensions of perceived usefulness, namely, performance‐related outcome expectations, personal‐related outcome expectations, and intrinsic motivation. Based on the technology acceptance model (TAM), a new expanded model is proposed to capture more details about students' perceptions of an online learning tool. I also examine the relationships of these three dimensions with perceived ease of use, attitudes, and behavioral intentions to use in the context of online technologies used as an integral component of the course requirements. My findings demonstrate the utility of the expanded TAM to distinguish between the influences of the three proposed dimensions. Results also show that, within the context of this study setup, intrinsic motivation had the most influence on intentions and perceived ease of use of the learning tool had relatively little importance. Limitations and implications are offered.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
