The effects of music and video on perceived exertion and performance of a cycling task at vigorous intensity

Physical activity can benefit all individuals by increasing their physical, mental, and emotional health. Therefore, finding ways to increase physical activity is a popular area of research. Researchers have found that using dissociative attentional strategies is effective in increasing physical activity. According to research, when administered individually music and video (dissociative strategies) are both effective in decreasing an individual's perceived exertion and increasing performance at low to moderate intensity activity. However, at vigorous intensities the results are less consistent. The potential effects of music and video presented simultaneously have not been compared to the effects of either in isolation. The purpose of this study was to determine if there was a difference in attentional focus and perceived exertion during vigorous intensity exercise as a function of being exposed to music, video, both (music and video), or nothing. Results showed that at vigorous intensity, participants in the condition that received both music and video perceived significantly lower exertion (RPE) and has a significantly more dissociative focus than did participants in the other three conditions. There was no significant difference amongst the other conditions. It was concluded that even at vigorous intensity exercise, a participant could use music and video to enhance their use of dissociative strategies and to perceive less exertion. The result of perceiving less exertion could lead to increased exercise adherence, which could have important implications for public health

The Ideal Qualities and Tasks of Library Leaders: Perspectives of Academic, Public, School, and Special Library Administrators

Our study examines the results of 114 interviews with academic, public, school media, and special library administrators collected over a one-year period in North Carolina. Preliminary results suggest that there is a core set of traits shared by administrators across libraries although some variation occurs depending on library environment. Implications center on the ability to inform degree preparation programs and practice by identifying primary qualities of library administration in general and specific to academic, public, school library, and special libraries

To Flash Or Not To Flash? Usability And User Engagement Of HTML Vs. Flash.

Of the many challenges facing developers of museum Web sites, usability and engagement rank high. Many developers have adopted Macromedia Flash as a useful tool that allows greater interactivity and multimedia compared to HTML pages. This paper reports on a comparative evaluation of Flash and HTML versions of a single site, focusing on user information-seeking goals, behavior, and responses to each version of the site. We then compare the two versions based on holding power, time on task, user satisfaction, and qualitative interviews. Testing found notable differences between the two versions of the site, and between youth and adult tester groups. The results provide valuable insights into the relative strengths and weaknesses of Flash and HTML. While we cannot draw broad conclusions from a single case study, these data can help us begin the discussion around developing preliminary standards and basic frameworks for suggesting rationales for choosing Flash or HTML in a number of typical situations facing museum Web developers

The Impact of Computer Augmented Online Learning and Assessment

The purpose of the study was to investigate the impact of an experimental online learning tool on student performance. By applying cognitive load theory to online learning, the experimental tool used was designed to minimize cognitive load during the instructional and learning process. This tool enabled students to work with programming code that was supplemented with instructor descriptions and feedback, embedded directly within the code while maintaining the original integrity of the coding environment. A sample of 24 online graduate students at a southeastern university were randomly assigned to four groups: Group 1 (Control group), Group 2 (Assessment group: the tool was used to provide feedback on student work), Group 3 (Lecture group: the tool was used to describe examples of code provided in lectures), and Group 4 (Total tool group: the tool was used to provide feedback on student work as well as describe examples of code in lectures). Student learning was measured via analysis of six online quizzes. While provision of tool-facilitated feedback alone did not appear to enhance student learning, the results indicate that students performed best when they had the opportunity to view examples of code facilitated by the tool during the learning process of new material. This implies a carefully designed online learning environment, especially while controlling for and minimizing cognitive load when presenting new information, can enhance that student learning

Systemic Change Going Public: Prelude to Scene 2

A paper presented at the Association for Educational Communications and Technology Annual Conference, October 31-Nov. 2, Louisville, KYThe Educational Systemic Change Web Project began 2011 as a move to bridge the gap between researchers and practitioners aligning with the division’s strategic goals. Project aims: begin a conversation about educational systemic change with practitioners, increase the systemic change profile on the Web, and serve as a viable resource center to practitioners. In this session, participants will view the published videos and website, determine how practitioners perceived the media, and discuss the gaps

The Website Design and Usability of US Academic and Public Libraries

This paper describes the results of a nationwide study which examined the design, layout, content, site management, and usability of 1,469 academic and public library websites from all 50 states in the United States. Our findings show common trends for homepage design, navigation, and information architecture. Library websites were found to consistently provide information about hours of operation (97.9 percent), library address (91 percent), news and events (88.9 percent), access to OPACs (84.6 percent), online renewal (77.7 percent), contact information (72.5 percent), and ability to give feedback (74.2 percent). Websites were mainly designed (33 percent) and managed (50 percent) by librarians as part of their professional job duties and the majority did not conduct any web usability testing (72.3 percent). This study provides a profile of how the nation’s academic and public libraries design and manage their websites and how this compares to recommended best practices from the research literature. Library websites rated high in general usability based on recognized heuristics; however, a need to conduct usability evaluations remains. A basic set of guidelines for library webpage design is proposed

College students' perceived threat and preference for seeking help in traditional, distributed and distance learning environments

The purpose of the present study was to examine how college students' help seeking behavior varied across different instructional learning environments. Four hundred and seventy four (N = 472) students enrolled in distance, distributed, and traditional classes were queried about their help seeking preferences, help seeking tendencies, personal threat in seeking help, and academic self-efficacy. It was hypothesized that students enrolled in courses with an online computer component would report (a) higher instances of help seeking behavior, particularly from instructors; and (b) feel less threatened to seek help than students in traditional learning environments. It was also expected that student achievement would be significantly correlated with formal help seeking, academic self-efficacy, and perceived threat to seek help. Lastly, it was postulated that students would report that they prefer to use electronic means to seek help and that they find it more effective. Overall the hypotheses of this study were supported. Educational implications and recommendations are provided regarding the type of technological tools that college instructors might consider using in their courses to promote help seeking

School Librarians and Web Usability: Why Would I Want to Use That?

The usability of a statewide curriculum website was evaluated involving 876 participants. Site usage differed based on user group and overall site content and relevance was found to be good along with high levels of satisfaction with graphic design. Usability problems with ease-of-use, however, were identified leading to the suggestion that many potential users do not use the site because of difficulty finding the information they are looking for. Implications of the research center on the articulation of a usability evaluation framework that could be generalized for testing the usability of other websites as well as redesign considerations for the site examined for the study

Information-Seeking Behavior and Reference Medium Preferences

The article looks at the differences in information seeking behavior among faculty, staff, and students at a university in the southeastern United States and what it means for library reference support strategies. The number of individuals using public and academic libraries for information is increasing, the article states, which means that librarians must assess their practices and services through studying user preferences. According to the study of university staff and students, most participants preferred face-to-face interaction for reference help, but technology such as email was preferred over phone calls and online chats. Other topics covered include demographic influence, gender differences, and convenience factors
