Stutterers' perceptions of more satisfying communication: Interaction strategies for fluent speakers

Persons who stutter must conduct their daily lives by interacting with fluent speakers. A majority of fluent speakers, however, are unaware of the communicative behaviors that can increase the frequency and severity of stutterers' dysfluencies. Moreover, extant research is scant regarding the strategies used by fluent speakers to increase interactive satisfaction with persons who stutter. This investigation addresses this void by sharing an empirical study in which stutterers offer the behaviors and strategies which they suggest result in more satisfying communicative interactions among fluent persons and stutterers.

Navigational Structures and Information Selection Goals: A Closer Look at Online Selectivity

Using an experimental design coupled with Web-tracking technology, this study explores 2 factors that influence levels of congruent information gathering online. The first factor compares the navigational structure of 2 distinct Web pages—the more open, user-directed search engine versus the organized, assembled structure of a portal Web page. The second factor tests the role of goals for information seeking—telling subjects they will soon engage in a discussion with another person who either disagrees with their viewpoint, agrees, is undecided, or no discussion treatment. Results indicate both experimental factors independently contribute to selectivity in online information seeking.     

The Role of Values in Predicting Talk Radio Listening: A Model of Value Equivalence

Nontraditional sources of news, such as talk radio and the Internet, complement and sometimes replace traditional mainstream news sources. Using discriminant function analysis, this study reveals the role of values in predicting listening to political talk and religious radio programs. A model using the construct of “value equivalence” explains value differences between user and media that may affect whether or not news from nontraditional sources will be sought and used. Research questions are answered using data from the 2004 Pew Research Center Biennial Consumption Survey. Using selected independent variables (including value-based variables) to predict listening to the Rush Limbaugh program, 59% of all cases in this study were correctly classified. Using the same set of value-based variables to predict listening to religious radio shows yielded nearly 74% correctly classified cases.     

A Note on Cluster Effects in Latent Class Analysis

This article examines the effects of clustering in latent class analysis. A comprehensive simulation study is conducted, which begins by specifying a true multilevel latent class model with varying within- and between-cluster sample sizes, varying latent class proportions, and varying intraclass correlations. These models are then estimated under the assumption of a single-level latent class model. The outcomes of interest are measures of bias in the Bayesian Information Criterion (BIC) and the entropy R ² statistic relative to accounting for the multilevel structure of the data. The results indicate that the size of the intraclass correlation as well as between- and within-cluster sizes are the most prominent factors in determining the amount of bias in these outcome measures, with increasing intraclass correlations combined with small between-cluster sizes resulting in increased bias. Bias is particularly noticeable in the BIC. In addition, there is evidence that class separation interacts with the size of the intraclass correlations and cluster sizes in producing bias in these measures.     

STUDENT RIGHTS TO RELIGIOUS EXPRESSION AND THE SPECIAL CHARACTERISTICS OF SCHOOLS

In this essay Bryan Warnick explores how rights to religious expression should be understood for students in public schools. Warnick frames student religious rights as a debate between the conflicting values associated with the Free Exercise Clause and the values associated with the Establishment Clause of the United States Constitution. He then asks how the special characteristics of the school environment should guide us in prioritizing those values. The overall weight of the considerations, particularly concerns about civic education, leads to a two‐pronged approach to religious rights. The first prong involves a robust protection of student religious exercise; the second involves an equally robust regime of school disassociation from student religious exercises.     

Pathway Towards Fluency: Using ‘disaggregate instruction’ to promote science literacy

This study examines the impact of Disaggregate Instruction on students’ science learning. Disaggregate Instruction is the idea that science teaching and learning can be separated into conceptual and discursive components. Using randomly assigned experimental and control groups, 49 fifth‐grade students received web‐based science lessons on photosynthesis using our experimental approach. We supplemented quantitative statistical comparisons of students’ performance on pre‐ and post‐test questions (multiple choice and short answer) with a qualitative analysis of students’ post‐test interviews. The results revealed that students in the experimental group outscored their control group counterparts across all measures. In addition, students taught using the experimental method demonstrated an improved ability to write using scientific language as well as an improved ability to provide oral explanations using scientific language. This study has important implications for how science educators can prepare teachers to teach diverse student populations.
