The differential effects of preschool: Evidence from Virginia

This study investigated the differential and persistent effects of a state-funded pre-K program, the Virginia Preschool Initiative (VPI). We analyzed data from a cohort of over 60,000 students nested in approximately 1000 schools from the beginning of kindergarten to the end of first grade using two-level hierarchical logistic regression models. While controlling for student- and school-level variables, we found that attending a VPI-funded program was beneficially associated with a lower likelihood of repeating kindergarten and improved probabilities of meeting or exceeding minimum literacy competencies. The benefits of attending pre-K were greatest upon kindergarten entry and persisted until the end of the first grade for Hispanic and Black students, as well as for students with disabilities, despite VPI-funded program attendees going to schools with higher concentrations of poverty.     

Gifted native American students: Underperforming,under‐identified,and overlooked

There has been limited focus among researchers on the nature and needs of gifted Native American students in the past 30 years, and the work that has been done frequently generalizes findings across Native American cultures. This article reviews recent literature on Native American youth and on gifted Native American students; examines the current condition of education in the Diné (Navajo) Nation through a sociocultural motivation lens and based on work with one tribal community on this reservation; calls researchers and educators to action and to recognize that, as with all ethnic groups, many individual cultures exist within Native American populations; and offers suggestions for education personnel. © 2012 Wiley Periodicals, Inc.     

Can dynamic visualizations improve middle school students' understanding of energy in photosynthesis?

Dynamic visualizations have the potential to make abstract scientific phenomena more accessible and visible to students, but they can also be confusing and difficult to comprehend. This research investigates how dynamic visualizations, compared to static illustrations, can support middle school students in developing an integrated understanding of energy in photosynthesis. Two hundred 7th‐grade students were randomly assigned to either a dynamic or a static condition and completed a web‐based inquiry unit that encourages students to make connections among energy concepts in photosynthesis. While working on the inquiry unit, students in the dynamic condition interacted with a dynamic visualization of energy transformation, whereas students in the static condition interacted with a series of static illustrations of the same concept. The results showed that students in both conditions added new, scientific ideas about energy transformation and developed a more coherent understanding of energy in photosynthesis. However, when comparing the two conditions, we found a significant advantage of dynamic visualization over static illustrations. Students in the dynamic condition were significantly more successful in articulating the process of energy transformation in the context of chemical reactions during photosynthesis. Students in the dynamic condition also demonstrated a more integrated understanding of energy in photosynthesis by linking their ideas about energy transformation to other energy ideas and observable phenomena of photosynthesis than those students in the static condition. This study, consistent with other research, shows that dynamic visualizations can more effectively improve students' understanding of abstract concepts of molecular processes than static illustrations. The results of this study also suggest that with appropriate instructional support, such as making predictions and distinguishing among ideas, both dynamic visualizations and static illustrations can benefit students. This study underscores the importance of curriculum design in ensuring that dynamic visualizations add value to science instructional materials. © 2012 Wiley Periodicals, Inc.

A Review of “Understanding the Semantic Web: Bibliographic Data and Metadata”

Successful subject searching depends upon the terminology of the search query. This paper compares the terminology of book titles with that of Library of Congress Subject Headings (LCSH) ¹ on a semantic level. Methods of ananlyzing titles into title phrases that serve as matching units are described. Guidelines used to choose LCSHs with the closest semantic matches to title phrases are set forth. The pairing of title phrases with semantically related LCSHs constitutes the data of the study. Categories representing the types of semantic relationships holding between pairs of terms are defined. Results of the study show that the most common semantic relationship holding between title phrases and LCSH is a hierarchical one where title phrases are more specific than LCSHs.     

Print Newspapers: Are They Still Being Used in Academic and Research Libraries?

A six-month print newspaper usage study at the University of Michigan's Hatcher Graduate Library showed a marked decrease in use from a more limited study done four years previously. In general, patrons used only the major national, international, and regional newspapers. Communications with other academic and research libraries confirm these findings.     

Teaching Master's and Doctoral Social Work Students to Systematically Evaluate Evidence-Based Interventions

Evidence-based research relevant to social work practice has grown dramatically. This article describes a method that was implemented to teach master's and doctoral social work students how to synthesize and evaluate evidence-based interventions for social work–related problems and populations. The method includes eight steps: conceptualize the problem and define the research question(s); conduct a systematic search; define study inclusion and exclusion criteria; identify and categorize types of interventions and outcomes; rate the studies' methodological rigor; determine outcome attainment; combine outcome attainment and study rigor, and compare the evidence across studies. Two examples are presented of the implementation of this approach along with a discussion of the challenges and limitations.     

The criteria of effective teaching in a changing higher education context

The criteria of effective teaching in higher education are understood to comprise particular skills and practices applied within particular contexts. Drawing on the literature and using Australia’s understanding of effective teaching, this paper examines the notion of effective teaching. The paper specifically compares dimensions derived from robust research and psychometric processes with the Australian Learning and Teaching Council’s criteria for effective teaching and observes the criteria of effective teaching in higher education to have evolved. While the paper suggests some areas in which future considerations of the notion of effective teaching might usefully focus, it also argues that context is critical and that it is subject to continuous and multiple changes imposed by forces from within and outside universities. The paper maintains that our collective understanding of competent, professional and effective teaching must continually evolve in order that it accurately reflects and continually responds to the contexts in which learning and teaching is undertaken. The paper also calls for an ongoing agenda that continuously investigates and articulates the meaning of effective teaching in a changed, and changing, context.
