MySpace Politics: Uses and Gratifications of Befriending Candidates

This study examines the uses and gratifications (U&G) of accessing political candidate profiles on social network Web sites. An online survey of visitors to the MySpace profiles of 2008 primary candidates revealed that voters are drawn to this source of political information mainly by the desire for social interaction with other like-minded supporters, followed by information-seeking, and entertainment. While information seeking and entertainment are common U&G of consuming online political content, they were weaker factors compared to the social interaction factor that seems to distinguish MySpace, possibly SNSs in general, from other online sources of political content.     

A review and new framework for instructional design practice variation research

This article reviews practice variation in the field of instructional design. First, it compares instructional designer practice as reported or observed in several classic research studies. This analysis is framed by the standards established by the International Board for Training, Performance, and Instruction competencies for planning and analysis, design and development, implementation, and management. Although no certain causal linkages exist, we briefly review some of the reasons posited in the literature to explain instructional design practice variation (lack of time and resources, control in decision making, the designer's perception of a task, underlying philosophical beliefs, and designer expertise). Limitations of the literature base are explored, followed by a proposal for an alternative view of instructional design practice variation and recommendations.     

Examining Contextual Effects in a Practice Analysis: An Application of Dual Scaling

Practice analyses are routinely used in support of the development of occupational and professional certification and licensure examinations. These analyses usually survey incumbents to obtain importance ratings of (1) specific tasks and (2) knowledge, skill, and ability (KSA) statements deemed by subject matter experts as essential to safe and effective practice. Several researchers have made important criticisms of traditional practice analysis procedures, particularly the lack of attention to contextual constructs and the resulting problematic interpretation of mean importance ratings. The present study provides a framework for assessing the impact of context in practice analysis studies. It focuses on a practice analysis of a health profession that sought to enhance the meaning of incumbents' importance ratings by embedding the statements in the context of patient acuities. Results indicate that incumbents' importance ratings varied as a function of patient acuity. Dual scaling analysis was used to obtain a multidimensional visual representation of the associations between importance ratings and contextual content. The implications of the contextual component of the study design for future practice analysis studies are discussed as well as possible applications of this approach to professions in education.

Instructional designers as reflective practitioners: developing professional identity through reflection

As the design thinking approach becomes more established in the instructional design (ID) discourse, the field will have to reconsider the professional identity of instructional designers. Rather than passively following models or processes, a professional identity rooted in design thinking calls for instructional designers to be dynamic agents of change who use reflective thinking to navigate the design space and develop solutions to ill-structured problems. Graduate programs in ID will also need to prepare students to manage the complexities they will encounter in their professional practice, including the establishment of design precedents, reflective thinking skills, and the foundations of professional identity. This research explored the use of reflective writing assignments in an introductory ID graduate course, with results indicating that most students are able to engage in meaningful reflection in relation to prompts concerning design concepts, experiences, and identity attributes, although no clear patterns of improvement emerged over time. Future directions for research include the use of feedback and the structure of prompts (including frequency of writing assignments and wording of prompts) to support improved student performance.     

Winning Beginnings Learning Circles: Outcomes from a Three-Year School Readiness Pilot

The current project examined school readiness outcomes of children participating in a preschool professional development initiative, Winning Beginnings Learning Circles, which focused on school readiness and teacher professional development. Children were assessed on knowledge and understanding of school readiness concepts in the fall and spring of each school year, and outcomes were reported back to preschool staff to be incorporated into teaching strategies. Preschool teachers and administrators attended monthly professional development seminars that consisted of workshops in child development and social-emotional health, parent engagement, and use of data as evidence-based best practices. Preschool assessment data from the first 2 years of the project showed significant increases in average scores from pre- to post-assessment on school readiness, self/social awareness, and quantity subtests. Kindergarten assessment data indicated that children who remained in the project for at least one full year outperformed comparable peers and the average for the school district they attended as kindergartners. The results highlight the potential of professional development programs and the importance of teacher quality in promoting positive outcomes for preschool children.
