The internet as a new distribution channel of scientific grey literature: The case of Italian WWW servers

The enormous range of information sources and communication services available on the Internet today recalls the information explosion and information overload that characterizes this century. We are certainly facing new kinds of information and communication patterns, based on direct electronic communication between end-users among themselves and/or between end-users and information sources. Moreover, this new channel of communication provides the opportunity to distribute different types of information, which in some cases are available only in a networked environment. The aim of this article is to analyze whether this new scenario has stimulated the production and the direct distribution of grey literature as well as changing its “traditional” features. The starting point of the study are the Italian WWW servers of the National Research Council.     

A multiage-grouping success story

How children organize themselves in play reflects groupings found in society. Multiage grouping in schools reflects the same. Multiage grouping is grouping children of multiple ages, at least one year apart, for instruction. With renewed interest in this practice comes anxiety for teachers who contemplate such a change. Some questions teachers often ask include: How do I get started?, and How do I organize the day? This article is the success story of one teacher as she began her multiaged classroom. Perhaps her story can answer some questions and serve as a beginning model for others.     

Total communication use among elementary teachers of hearing-impaired children

This study examined the degree to which teachers' signed Manually Coded English messages represented their spoken utterances. Results indicate that educators in early elementary programs can, and do, provide a complete manual representation of their spoken English messages. This is in contrast with earlier research with middle school educators and parents of hearing-impaired children. Findings indicate that MCE proficiency may be influenced both by teacher attitude regarding the importance of signing a complete message and the degree to which program supervisors monitor teacher implementation of clearly specified MCE policies. Findings from this study have implications for programs to train teachers in using MCE and also provide information on the effects of program policy on teacher use of sign language.     

Situating teacher inquiry: a micropolitical perspective

Professional learning communities (PLCs) have become a popular strategy in various forms (e.g., data teams, grade-level teams) and with various champions (e.g., district leaders, university researchers, teacher advocates). Although well-implemented PLCs have been shown to distribute leadership, the tension between democratic inquiry processes and the demands of accountability remain understudied. This study asks how teacher inquiry is situated within conflicting school priorities and the impact of competing power structures on PLCs through a case study of a teacher inquiry initiative at 6 urban elementary and middle schools in the US. Data were collected over 3 years of PLC implementation. District officials, principals, reform coaches, and teachers at each setting participated in more than 300 interviews, regular site visits, and annual teacher surveys. The influences of power structures – such as district mandates, accountability pressures, and principal leadership – emerged as strong themes in teacher narratives of what it means to “do” inquiry in their PLCs.     

Speed Versus Accuracy: Implications of Adolescents' Neurocognitive Developments in a Digital Game to Train Executive Functions

Adolescence is a period of rapid cognitive change, including an initial increase in speed of cognitive processing and a more gradual increase in efficiency of cognitive processing. This study examined how neurophysiological changes associated with adolescent development can inform the design of game‐based executive function (EF) training. Two versions of a digital game designed to train the EF subskill of inhibition were given to adolescents (aged 13–17; N = 96): one focusing on speed, the other on accuracy. Consistent with neurocognitive developments, it was hypothesized that younger adolescents would benefit more from the speed version, and older adolescents more from the accuracy version. A significant age by condition interaction was found: Controlling for pretest, younger adolescents had better outcomes in the speed condition, while older adolescents had better outcomes in the accuracy condition. These findings argue for consideration of adolescents' neurocognitive development when designing games for learning and skill improvement.     

The Effectiveness of Collaborative Augmented Reality in Gross Anatomy Teaching: A Quantitative and Qualitative Pilot Study

In the context of gross anatomy education, novel augmented reality (AR) systems have the potential to serve as complementary pedagogical tools and facilitate interactive, student-centered learning. However, there is a lack of AR systems that enable multiple students to engage in collaborative, team-based learning environments. This article presents the results of a pilot study in which first-year medical students (n = 16) had the opportunity to work with such a collaborative AR system during a full-day gross anatomy seminar. Student performance in an anatomy knowledge test, conducted after an extensive group learning session, increased significantly compared to a pre-test in both the experimental group working with the collaborative AR system (P < 0.01) and in the control group working with traditional anatomy atlases and three-dimensional (3D) models (P < 0.01). However, no significant differences were found between the test results of both groups. While the experienced mental effort during the collaborative learning session was considered rather high (5.13 ± 2.45 on a seven-point Likert scale), both qualitative and quantitative feedback during a survey as well as the results of a System Usability Scale (SUS) questionnaire (80.00 ± 13.90) outlined the potential of the collaborative AR system for increasing students' 3D understanding of topographic anatomy and its advantages over comparable AR systems for single-user experiences. Overall, these outcomes show that collaborative AR systems such as the one evaluated within this work stimulate interactive, student-centered learning in teams and have the potential to become an integral part of a modern, multi-modal anatomy curriculum.
