Contributions Of Teachers To Dental Health Knowledge And Behavior Of Students

For the K-sample Siegel-Tukey and Klotz tests on variance, Penfield and Koffler published, in this journal, test-statistic formulas that yield excessively liberal tests. The degree of liberalness is demonstrated, and corrected formulas are presented and illustrated in this paper.     

Dumbstruck: A Cultural History of Ventriloquism

This tropological analysis of “On the Equality of the Sexes” (1790) argues that Judith Sargent Murray deployed a series of ironic reversals, including an example of Kenneth Burke's “dialectical” irony, to make her famous case for women's capacity to reason. As such, the article elucidates this trope's peculiar rhetorical potential within the context of eighteenth-century debates on female education and investigates how it can function in conjunction with romantic irony. Significantly, Murray deployed romantic irony in order to question her era's commonplace ideas about women's intellectual capacities and conventional female education. She then employed dialectical irony in order to sidestep relativism, playing off and departing from the expanded field of possibilities that romantic irony opened up. In so doing, she cast doubt upon commonly held doubts themselves, questioning the subversiveness normally associated with learned ladies. Through this series of ironic turns, readers were invited to change their previous beliefs and then presented with a clear means of moving forward—thereby opening a path for elite European American girls to be educated in traditionally masculine domains.     

Social Information Processing,Moral Reasoning,and Emotion Attributions: Relations With Adolescents’ Reactive and Proactive Aggression

Connections between adolescents’ social information processing (SIP), moral reasoning, and emotion attributions and their reactive and proactive aggressive tendencies were assessed. One hundred mostly African American and Latino 13‐ to 18‐year‐olds from a low‐socioeconomic‐status (SES) urban community and their high school teachers participated. Reactive aggression was uniquely related to expected ease in enacting aggression, lower verbal abilities, and hostile attributional biases, and most of these connections were mediated by adolescents’ attention problems. In contrast, proactive aggression was uniquely related to higher verbal abilities and expectations of more positive emotional and material outcomes resulting from aggression. Discussion focused on the utility of assessing both moral and SIP‐related cognitions, and on the potential influence of low‐SES, high‐risk environments on these findings.     

R&D Funding Sources and University Technology Transfer: What Is Stimulating Universities to Be More Entrepreneurial?

In recent years, universities have become increasingly entrepreneurial as evidenced by their rapid escalation into technology transfer, the process by which university-developed technologies are commercialized. Stimulated in part by a favorable policy environment for patenting and licensing as well as increased competition for limited resources, university commercially oriented activities are nevertheless risky and controversial. Yet, it is unlikely this trend will be reversed, and hence research to inform its responsible practice is needed. This study investigates the effect of core R&D resources on university licensing to small and large companies, two important but distinct forms of licensing activity. Implications of the findings for policy and practice are offered.     

Globalization or Glocalization? Higher Education Reforms in Singapore

Globalization and the evolution of the knowledge‐based economy have caused dramatic changes to the character and functions of higher education in most countries around the world. However, the impacts of globalization on universities are not uniform though business‐like practices have been adopted to cope with competition in the global marketplace. The pressure for restructuring and reforming higher education is mainly derived from growing expectations and demands of different stakeholders in society. In recent years, widespread concerns over widened access, funding, accountability, quality, and managerial efficiency are perceived as the prominent global trends related to university education. Because of the divergent political, social, economic, cultural and historical backgrounds, national/local governments may adopt similar strategies in response to pressures generated from globalization. Nonetheless, through a close scrutiny of the ways that national policies are made, we may find that governments around the globe, particularly in East Asia, have tried to make use of the globalization discourse to address/justify the local policy/political agendas. This paper aims to examine the latest higher education reform initiatives proposed by the Singapore Government, with particular reference to reflect upon how the Singapore Government reforms its university systems in the context of globalization. It is argued that the latest comprehensive review of public university governance and funding brings about a changing role of the government in the regulation, finance and provision of higher education in Singapore and eventually alters the state‐university relationship.     

Conditional cooperators: student prosocial dispositions and their perceptions of the classroom social environment

A common problem in education is getting students to cooperate effectively in groups during learning. Because interdisciplinary research has established that cooperation is sensitive to specific contextual factors such as reciprocity, friendship and benefit, similar factors could be shaping student interactions in contemporary classroom environments. The present article reports an initial investigation of this idea by examining how student perceptions of their classroom environment relate to their willingness to expend energy and resources on classmates (through helping). This was accomplished through the structural equation modeling of survey data collected from 845 undergraduate life sciences students from 41 laboratory classrooms at a research-intensive university. Characteristics of the classroom social environment previously associated with benefits in other contexts also predicted (reciprocity β = 0.576; friendship β = 0.156) the educational benefit that students perceive as coming from their classmates. This perceived benefit in turn was highly associated (β = 0.605) with student willingness to expend resources on classmates (i.e. their prosocial disposition). Also both reciprocity (β = 0.298) and perceived benefit (β = 0.403) concurrently predict a student’s support for enforcing cooperation in the classroom. Potential insights into the contribution of classroom social environment to student dispositions towards cooperation are discussed.     

Exploring the Robustness of a Unidimensional Item Response Theory Model With Empirically Multidimensional Data

Unidimensionality and local independence are two common assumptions of item response theory. The former implies that all items measure a common latent trait, while the latter implies that responses are independent, conditional on respondents’ location on the latent trait. Yet, few tests are truly unidimensional. Unmodeled dimensions may result in test items displaying dependencies, which can lead to misestimated parameters and inflated reliability estimates. In this article, we investigate the dimensionality of interim mathematics tests and evaluate the extent to which modeling minor dimensions in the data change model parameter estimates. We found evidence of minor dimensions, but parameter estimates across models were similar. Our results indicate that minor dimensions outside the primary trait have negligible consequences on parameter estimates. This finding was observed despite the ratio of multidimensional to unidimensional items being above previously recommended thresholds.     

Designing customizable reading modules for a high school literature classroom

This design case follows an ongoing collaboration between an instructional technologist and a high school literature teacher promoting reading comprehension through modules that provide visually interesting display of text on a computer screen along with cognitive tools. The modules were found to boost comprehension of specific content in even one use, and over time, overall reading skills were improved. Specific examples from the design and development process of this collaboration are shared here to illustrate decisions made in the face of common constraints—limited time, funding, and technical know-how—that emerged from theory and pilot studies. Teacher educators and their instructional-technology collaborators can use the information from this design and research process to harness the potential of ubiquitous software in affordable, replicable, and pedagogically sound ways.
