Technical Note: Using Latent Class Analysis versus K‐means or Hierarchical Clustering to Understand Museum Visitors

This paper discusses the benefits of using Latent Class Analysis (LCA) versus K‐means Cluster Analysis or Hierarchical Clustering as a way to understand differences among visitors in museums, and is part of a larger research program directed toward improving the museum‐visit experience. For our comparison of LCA and K‐means Clustering, we use data collected from 190 visitors leaving the exhibition Against All Odds; Rescue at the Chilean Mine in the National Museum of Natural History in January 2012. For the comparison of LCA and Hierarchical Clustering, we use data from 312 visitors leaving the exhibition Elvis at 21 in the National Portrait Gallery in January 2011.     

The Power of Expectation

Abstract In 1999, the first author and his colleagues at the Smithsonian Institution published an article in Curator: The Museum Journal introducing research on the experiences visitors find satisfying in museums. Subsequent data collection has expanded on these findings, as this Research Note will elucidate. In general, the team found that experiences that visitors were looking forward to on entrance tended to have a distribution similar to that of the experiences they found satisfying on exit. The aim of this note is to present data that demonstrates this consistency, and to observe that visitors’ expectations that they would have certain types of experiences upon entering a museum or exhibition were a much larger factor in determining their responses than were minor differences in museum or exhibition content or presentation. In other words, on the whole they came in knowing what experiences they expected, and they left having found them, regardless of what museum personnel presented to them inside.     

Religious socialization of youth involved in child welfare

Increased religiosity is associated with a variety of improved outcomes, especially for youth in disadvantaged contexts. Although youth involved in child welfare may experience protective effects of religious participation or values, little is known about the impact of maltreatment on religious development. Using the National Survey of Child and Adolescent Well-Being, a nationally representative study of child welfare involved families, correlates of religious attendance and importance of religion for youth were investigated using weighted logistic regression at two waves 18 months apart. Youth self-reports of religious attendance and their ratings of its importance were associated with religious attendance of their caregivers, whether birth-parents or foster parents. Foster parents were more likely to attend religious services than birth parents. Increases in youth attendance from Wave 1 to Wave 2 were associated with high youth religious importance at Wave 1, whereas decreases in attendance were associated with moving between home and foster placements. Increases in religious importance from Wave 1 to Wave 2 were associated with religious attendance at Wave 1 and with the youth being Black.     

Academic growth trajectories of ELLs in NAEP data: The case of fourth- and eighth-grade ELLs and non-ELLs on mathematics and reading tests

Utilizing the National Assessment of Educational Progress (NAEP) data, this study examined (1) how fourth and eighth-grade ELLs' mathematics and reading scores on national tests compared to their non-ELL peers' scores over the testing period between 2003 and 2011, and (2) if gender and ethnicity contributed to variation in the growth patterns among the student groups across grade levels and content areas. Since the NAEP data, which provides a national sample of 10,000–20,000 students, is collected using a probability sample design, sampling weights are adjusted so inferences can be appropriately made. Sample sizes within NAEP are large enough to generate adequate power for statistical significance. Thus, to display the data in a multivariate mode, Tableau 8.0.0 software was used. Results suggested that the achievement gap between non-ELLs and ELLs is either steady or slightly widening in both mathematics and reading, with multiple paths across the content areas, grade levels, and gender and ethnic groups.     

Advocating for Sustainability: A Report on and Critique of the Undergraduate Capstone Course

ABSTRACT

The authors provide an overview of what capstone courses do by presenting information from across the field based on materials received from and interviews with technical and professional communication program administrators and faculty. The authors then point to opportunities to improve the course. Finally, the authors argue for sustainable program development as the theoretical framework to perform programmatic work.
