The main aim of this study was to gather teachers' views to determine the effect size of gender differences on the instructional leadership behavior of school principals. The standardized mean difference (SMD) was calculated to measure the effect size in this study. An initial search yielded 126 studies on the research topic, which consists…

Previous studies have proposed that humans may be born with mechanisms that attend to conspecifics. However, as previous studies have relied on stimuli featuring human adults, it remains unclear whether infants attend only to adult humans or to the entire human species. We found that 1-month-old infants (n = 23) were able to differentiate between…

Infants' understanding of a pointing gesture represents a major milestone in their communicative development. The current consensus is that infants are not capable of following a pointing gesture until 9-12 months of age. In this article, we present evidence from 4- and 6-month-old infants challenging this conclusion. Infants were tested with…

Infants' transfer of information from pictures to objects was tested by familiarizing 9-month-olds (N = 31) with either a color or black-and-white photograph of an object and observing their preferential reaching for the real target object versus a distractor. One condition tested object recognition by keeping both objects visible, and the…

Previous studies have shown that people start traveling sales problem tours significantly more often from boundary than from interior nodes. There are a number of possible reasons for such a tendency: first, it may arise as a direct result of the processes involved in tour construction; second, boundary points may be perceptually more salient than…

This study aims at gaining a better understanding of the current state and needs of RDA training among cataloging and metadata practitioners. Using nationwide survey data focusing on the academic library sector, this study finds that while training activities since RDA's release in 2010 show a positive correlation with catalogers' levels of RDA…

Several methodological approaches to improve the understanding and motivation of students in Hydraulic Engineering courses have been adopted in the Agricultural Engineering School at Technical University of Madrid. During three years student's progress and satisfaction have been assessed by continuous monitoring and the use of…

Interculturalism, in its two forms, critiques multiculturalism. A European version emphasises cultural encounter and novelty, and is relatively apolitical except for its disavowal of the national in preference for the local and the transnational. In contrast, its Quebecan counterpart gives significance to the idea of the right of a national…

The goal of this study is to report the results of a comparative usability study conducted in 2008-2009 on two different course management systems (CMS), BlackBoard and Moodle. 135 students enrolled in the fall 2008 and spring 2009 section of Introduction to Educational Technology participated in the study (72 and 63 respectively). At the…

While the delivery and reception of advice is a practice integral to a wide range of settings, little attention has been given to the detailed practices of advice resistance and how it leads to advice negotiation. Based on 7 hours of videotaped tutoring interactions among 6 tutors and 11 tutees, this conversation analytic study examines the…

Emerging adult college students have developmental and educational needs which are unique to their phase of life. The purpose of this study was to examine academic and non-academic technology use by emerging adult college students. Survey results (N = 235) provided insights into emerging adult college student technology preferences and frequency…

We examined whether the results of a response-restriction analysis (RRA) could be predicted on the basis of response distribution in early sessions, when these sessions indicated interaction with multiple items. Four preschool-aged children participated. For 3 of the 4 participants, the results from sessions conducted prior to restriction of the…

Recent research reflects a growing awareness of the value of using structural equation models to analyze repeated measures data. However, such data, particularly in the presence of covariates, often lead to models that either fit the data poorly, are exceedingly general and hard to interpret, or are specified in a manner that is highly data…

This study tests the hypothesis presented by Penke, Denissen, and Miller (2007a) that condition-dependent traits, including intelligence, attractiveness, and health, are universally and uniformly preferred as characteristics in a mate relative to traits that are less indicative of condition, including personality traits. We analyzed…

From preschool age to adulthood, most humans prefer to help someone who has treated others well over helping someone who has treated others badly. Researchers have recently made opposing predictions about whether such observation-based preferential helping is present when children begin to help in the second year of life. In the present study, 84…
