One reason might be a relatively low explanatory power for the main construct, i.e., task technology fit, in the model. In this study, we suggest content characteristics as a new determinant of fit, and empirically test it along with the two existing determinants, task and technology characteristics with 105 users of a web-based learning management system. In order to verify the contribution of content characteristics to the explanatory power, both task technology fit models with and without content characteristics are tested and compared. The results support that the addition of content characteristics dramatically increases the explanatory power for the task technology fit.

In this study, we employ the five focus areas of experiential learning and investigate their effects on student learning outcomes. The preliminary analysis of results shows that the assessment of experiential learning with the five focus areas of experiential learning such as communication, leadership, professionalism, problem solving, and teamwork are statistically valid, and experiential learning contributes to student learning outcomes

These theories focus only on task types and technology characteristics as determinants of task-technology fit, which in turn impacts performance. Information quality, which is an important deliverable when someone uses information technology for a task, has not been discussed as a possible determinant. In this study, we argue that given the importance of information and knowledge content in modern systems, information quality can contribute to the fit evaluation as another determinant of fit. We empirically tested a task technology fit model, applying a “fit as matching” perspective in the context of a simple task and communication technology. The results show that the addition of information quality in the model increases the explanatory power for the fit and the ultimate dependent variable, performance. The findings point to the importance of information q...

According to eMarketer’s report (2015), people have spent more time with digital video than with social media since 2015. In addition, Cisco predicts that 80% of global Internet consumption will be video content by 2019. We can easily observe this rapid growth of video contents in the industry (e.g., YouTube, Facebook, and Netflix) as well as the education (e.g., Khan Academy, Lynda.com, and online schools). Recently, video contents have increasingly been used for online and blended learning classes in universities and colleges. However, there has been little research attention on understanding whether and how people have adopted the video contents for learning. In this study, we develop a research model to examine the adoption of video lectures for learning with theories of technology acceptance and task technology fit. While both theories have been used in the study of technology adoption, they focus on different aspects of adoption. For example, the technology acceptance model focuses on individual acceptance of technology based on perceptions of usefulness and ease of use, but the task technology fit model focuses on the fit between different types of task and technology. Dishaw and Strong’s (1999) argue that an integrated TAM/TTF model can provide better understanding of technology utilization and adoption than either individual model. We employed and adapted their integrated model of TAM/TTF to understand the adoption of video lectures for learning. Our research model has been assessed with the data collected from three online and blended classes in southeastern universities. Preliminary results from the partial least squares analysis show that content quality of video lectures positively affects the user’s perception of fit in using video lectures for learning, and the better fit would increase perceived usefulness and adoption of video lectures for learning. Our research also investigates how gender plays a role on the adoption of video lectures for learning. Gender has received research attention as a factor influencing IT adoption. Gefen and Straub (1997) tested and found gender difference in the adoption of communication technology such as an e-mail service. Building upon prior research on technology adoption, we include and test gender as a moderator in the adoption of video lectures for learning. The finding from this research would help us better understand quality control and gender difference in employing video lectures for online/blended learning

In this study, we examine the adoption of short message service (SMS) with the technology acceptance model. The model has been assessed with the data collected from 225 SMS users. Results from the partial least squares analysis show that perceived ease of use of SMS positively affects perceived usefulness of SMS and intention to adopt SMS, and perceived usefulness of SMS also positively affects intention to adopt SMS. Comparing the two factors, perceived usefulness is more influential than perceived ease of use in the SMS adoption, which implies that extrinsic, i.e., task-oriented, characteristics of SMS may be more important than its intrinsic characteristics in the adoption decision. This study includes how the gender moderates the effects of the two factors on the SMS adoption, showing that the effec...

A CRS instantly collects, tallies, and shows students' answers to a question on a classroom projection screen—a similar system used in the TV show "Who wants to be a millionaire" to collect audience responses. In this paper, the author proposed a comparable technology—Google Forms—that can be used in a computer lab and then studied gender differences in the relationship between the use of Google Forms and performance changes. Performance was measured by both the letter grades distribution and raw exam scores. The initial results suggested that the use of Google Form did not make any difference in the performances measured by the letter grades distribution. However, when the raw exam scores were compared with a covariate of calculus grades, the results suggest that the use of Google Forms resulted in improved per...

This study introduces perceived instructor presence as a way to promote such interactions and investigates its effects on student learning experience in online learning. Background: Drawing upon theories of constructivism and social presence, this study proposes a research model to explore the causal relationships from the interactivity of a communication tool to the perception of instructor presence and to student learning experiences such as engagement and satisfaction. Methodology: The survey method was used to collect data from online business classes where an interactive communication tool was required to use for class communication and collaboration. Partial Least Squares analysis was used as the primary data analysis tool. Contribution: This study introduces perceived in...

However, there have been challenges to students’ learning experience in online learning. One critical challenge would be providing interactions between students and instructors as good or effective as in the face‐to‐face environment. However, providing face‐to‐face interactions in online learning is not feasible because students and instructors are not physically present together. In this study, we introduce and empirically investigate social presence as student learning experience in online learning in which physical presence does not exist. Drawing upon the social presence and online learning literature, we propose a research model to explore how the interactivity of communication tools can drive social presence and student satisfaction in online learning. Furthermore, this study examines gender difference as a moderator in the model. Data were collected from u...

One interesting observation on sharing economy platforms is unprecedented amount and use of identity information about peer-providers. Peer-providers offer rich information about themselves, and a sub-set of such identity information is verified on some sharing economy platforms. However, there has been little research on such identity information sharing and the impacts of such information on peer-consumers’ decision making. In this study, we propose a research model to explain the role of identify information on sharing economy platforms, and empirically test the proposed model in the context of a lodging service sharing economy platform, Airbnb. Our results show that identity information shared by peer-providers contributes to peer-consumers’ consumption intention through social presence and trust. The implications of these findings and directions for future research are discussed.

Three dimensions of fit:Task Match, Ease of Use, and Ease of Learning, are applied in the context of digital video tools use for oral presentation in a classroom environment. Students completed a digital video presentation that acted as a substitute for an in-class oral presentation. An existing survey instrument was adapted, and administered to the students to examine the impact on presentation skill and fit to task. Results confirm the adaptation of the TTF model and show significant relationships between variables. The model can be used in other task/technology combinations. Additional findings suggest that when there is a significant fit between digital video tools (technology) and improvement of oral presentation skills (task), student performance also improves. Digital video can be a useful alternative to in-class presentation when the goal is to improve presentation skill.

While there are a variety of factors influencing the reluctance to report, prior information systems research has focused on only situational factors such as risk, information asymmetry, and time pressure involved in the given situation. In this paper, we examine the effects of both situational and personal factors on an individual's reporting behavior within the rubric of the basic whistle-blowing model adapted from Dozier and Miceli [1]. Specifically, we identify perceived impact of information technology (IT) failure as a situational factor and personal morality and willingness to communicate as personal factors, and investigate their effects on the assessments and decisions that individuals make about reporting the IT project's status. Based on the results of a controlled laboratory experiment, we found that perceived impact of IT failure directly affects an individual's assessment of whether a troubled project's status ought to be reported, exerting an indirect influence on willingness to report bad news, and that personal morality directly affects all three steps in the basic whistle-blowing model, as hypothesized. Willingness to communicate, however, was found not to affect an individual's willingness to report bad news. The implications of these findings and directions for future research are discussed.
