Hypermedia navigation: Profiles of hypermedia users

In this study we explored the use of log files as a window into the process of hypermedia navigation. Although there is a growing body of research addressing theoretical and design issues related to open-ended, non-directive technologies such as hypermedia, relatively few studies have attempted to explain navigational performance. Sixty-six undergraduate students used a multidimensional, computer-based kiosk that could be explored in a nonlinear fashion to find information in response to one of two information-retrieval tasks (simple or complex). Cluster analysis was used to generate performance profiles derived from navigational data captured in log files. Analyses of within-cluster performance profiles, combined with external validation criteria, led to the classification of four different types of navigational performance (models users, disenchanted volunteers, feature explorers, and cyber cartographers). These characterizations were consistent with information-retrieval scores and the external criteria (self-efficacy, perceived utility, and interest). For example, individuals who appeared to take the time to learn the layout of the kiosk also had the highest self-efficacy, while those who used the help screen and watched the most movies had the lowest self-efficacy. Results also demonstrated an interaction between various individual navigational profiles and type of information-retrieval task.     

Designing System Dualities: Characterizing a Web-Supported Professional Development Community

In this article we focus on the challenges we have encountered in attempting to support the development of an online community of practice for grade 5-12 mathematics and science teachers. Specifically, this project involves the design and evaluation of an electronic knowledge network, the Inquiry Learning Forum (ILF), a web-based professional development system designed to support a community of practice (CoP) of in-service and preservice mathematics and science teachers who are creating, reflecting upon, sharing, and improving inquiry-based pedagogical practices. This research examines the interplay among a variety of variables that characterize the dynamics of building a social network through which participating teachers will seek to share and improve their pedagogical practices. Our research suggests that designing for virtual communities involves balancing and leveraging complex dualities from the "inside" rather than applying some set of design principles from the "outside." This research provides an illuminative case study from which others can more readily identify patterns occurring in their own interventions and navigate the challenges they face more intelligently.     

Navigating Sexualization as a Sexuality Professional: Recommendations from Sexuality Educators at the 2016 National Sex Ed Conference

Sexuality professionals are likely to experience unwanted sexualization based solely on their profession. Sexuality professionals are sexualized by various groups of people including strangers, colleagues, or even friends and family. The research literature discusses how sexuality researchers experience and navigate this sexualization but includes little information about the ways in which sexuality educators are sexualized. At the 2016 National Sex Ed Conference, we facilitated a workshop for sex educators to discuss how they are sexualized and how they would suggest navigating such experiences. Through this workshop proceeding, we examine how educators echoed many of the same strategies used by sexuality researchers found in the literature along with some unique population concerns and strategies.
