Enhancing preschool children's vocabulary: Effects of teacher talk before,during and after shared reading

This observational study analyzed patterns of teacher extratextual talk as it occurs before, during, and after reading books to children, and the frequency and duration of teacher questioning by type (label, define, associate) on preschoolers’ receptive and expressive vocabulary knowledge. Over the course of 18 weeks, 13 teachers and 100 children participated in ninety 20-min small-group sessions of teacher-guided shared reading instruction. Teachers’ reading instruction was examined through videotaped observations using the Multi-Option Observation System for Experimental Studies (MOOSES™; Tapp, Wehby, & Ellis, 1995). Two findings, in particular, yielded relevant educational and theoretical implications. First, time spent after reading was significantly related to expressive vocabulary. However, question timing did not seem to matter in terms of receptive vocabulary outcomes. Second, duration of teacher association questioning was significantly related to receptive vocabulary outcomes while both frequency and duration of teacher vocabulary-related association-level questioning were related to expressive vocabulary. For receptive vocabulary, both vocabulary- and comprehension-related association-level questioning mattered. These findings complement the body of work demonstrating that engaging children in interactive shared reading that elicits their active participation is related to meaningful gains in children's language and literacy growth. Limitations of the study and directions for future research are discussed.     

Knowledge Management and Library Culture

Knowledge management (KM), or the effective use of knowledge, has been practiced successfully by many business organizations. Individual libraries and librarians have periodically utilized KM. However, on a comprehensive scale, the library culture seems divided. This article examines the attitudes and practices of two distinct groups of specialized librarians and their relationship to the use of KM tools.     

Weaving a Web Within the Web: Corporate Consolidation of the Web, 1999–2008

Scholars have repeatedly debated whether the Web serves as an alternative to traditional media consolidation. To explore this issue further, the author examines Web site ownership trends over a 10-year period, finding evidence of ownership consolidation among popular Web properties. In addition, the author finds that traditional media corporations have consolidated their influence over the Web. In the end, the author suggests that the Web does not serve as an alternative to media consolidation.     

Retransmission Consent,Cable Franchising,and Market Failure: A Case Study Analysis of WOOD-TV 8 Versus Cablevision of Michigan

Today, many media corporations are linked together through interlocking boards of directors. Are these interlocks legal, especially in an ever-converging media environment? This study of interlocks finds that over 40% of leading media corporations are interlocked with another leading media company. The majority of these interlocks are legal under current media conditions, but that may change as media formats converge. In addition, the legality of 2 board interlocks is questioned and discussed.     

When Off-Campus Means Virtual Campus: The Academic Library in Second Life

ABSTRACT

This article discusses how a library's consistent policy of accessibility and foresight positioned itself to serve its students, faculty and staff in the virtual world of Second Life. Always ahead of the technological curve, this library has been the front-runner in providing services to distance learners via text messaging, “chat,” e-mail, and telephone services and via its laptop librarian project across the campus. It now is poised and ready to provide service in Second Life. Collaboration between the library and teaching faculty culminated in the creation, development, and furnishing of a library in Second Life, an environment that gives new meaning to “off-campus” learning. Without marketing, but as a visible presence, the Second Life library was able to attract both off-campus guests and affiliated students and faculty and even participated in campus-wide projects. This experiment has enjoyed the support of both the university and library administration.     

PUSH(ing) Limits: Using Fiction in the Classroom for Human Behavior and the Social Environment

The use of fiction and autobiography in social science course work has been shown to enhance students' learning experience. Using the novel PUSH, by Sapphire, we designed a curriculum supplement for the social work course, human behavior and the social environment (HBSE) that encourages students to integrate course content in an innovative way and enables them to apply the material to life-like situations. The HBSE supplement allows students to explore poignant and problematic issues that push them past intrapersonal and interpersonal limits. Classes are infused with energy and the critical consciousness of the students. Final projects are a systematic case study of a chosen character (or characters) in the book and are a testament to student critical thinking and creativity. Methods, assignments, and student experiences in an introductory BSW course are described.     

Adverse Childhood Experiences Among MSW Students

This study examined the extent to which age, education, and practice experience among social work graduate students (N = 184) predicted cognitive complexity, an essential aspect of critical thinking. In the regression analysis, education accounted for more of the variance associated with cognitive complexity than age and practice experience. When age and direct practice experience were controlled for, education accounted for 6% of the variance in cognitive complexity. Results suggest that education experience may play a more important role in social work student cognitive complexity than age or practice experience. Implications for social work education and assessing student cognitive development are discussed.     

Academic users’ interactions with ScienceDirect in search tasks: Affective and cognitive behaviors

This article presents part of phase 2 of a research project funded by the NSF-National Science Digital Library Project, which observed how academic users interact with the ScienceDirect information retrieval system for simulated class-related assignments. The ultimate goal of the project is twofold: (1) to find ways to improve science and engineering students’ use of science e-journal systems; (2) to develop methods to measure user interaction behaviors. Process-tracing technique recorded participants’ processes and interaction behaviors that are measurable; think-aloud protocol captured participants’ affective and cognitive verbalizations; pre- and post-search questionnaires solicited demographic information, prior experience with the system, and comments. We explored possible relationships between affective feelings and cognitive behaviors. During search interactions both feelings and thoughts occurred frequently. Positive feelings were more common and were associated more often with thoughts about results. Negative feelings were associated more often with thoughts related to the system, search strategy, and task. Learning styles are also examined as a factor influencing behavior. Engineering graduate students with an assimilating learning style searched longer and paused less than those with a converging learning style. Further exploration of learning styles is suggested.
