Advances in the publishing world have emerged new models of digital library development. Open access publishing modes are expanding their presence and realize the digital library idea in various means. While user-centered evaluation of digital libraries has drawn considerable attention during the last years, these systems are currently viewed from the publishing, economic and scientometric perspectives. The present study explores the concepts of usefulness and usability in the evaluation of an e-print archive. The results demonstrate that several attributes of usefulness, such as the level and the relevance of information, and usability, such as easiness of use and learnability, as well as functionalities commonly met in these systems, affect user interaction and satisfaction. 相似文献

Dimensions of Perceived Usefulness: Toward Enhanced Assessment 总被引：1，自引：0，他引：1

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. 相似文献
