Parents’ Use of the V-Chip and Perceptions of Television Ratings: The Role of Family Characteristics and the Home Media Environment

Nearly 20 years after the Telecommunications Act of 1996, it is unclear how its mandates influence current parents’ mediation behavior. Parents of 2- to 17-year-old children (N = 1,431) were surveyed about their awareness and perceptions of the TV ratings system and use of the V-chip. Most (81%) parents knew about the ratings system and found it to be only “somewhat useful.” Only 16% of those parents had ever used the V-chip. Ratings awareness and perceptions and V-chip use varied with family characteristics. Policymakers should revisit how to provide better tools for mediating children’s viewing in this new information age.     

Transfer of a taste aversion from food to water under various states of deprivation

The importance of ingestive contexts (feeding and drinking) and deprivation states to rats’ transfer of a taste aversion were examined, In Experiments 1 and 2, rats were trained with novel saccharin-treated foods while either food deprived or food and water deprived, They were then tested with a 1,0% saccharin solution while either water deprived or food and water deprived, Comparable aversions to the solution were displayed regardless of deprivation states, Two further experiments examined transfer to a .1% saccharin solution in conjunction with deprivation state change, When both stimulus properties and deprivation were widely discrepant from training to test, reduced transfer was noted. The results suggest that stimulus similarity was a stronger controlling variable than deprivation state similarity in facilitating the transfer of an aversion from a feeding context to a drinking context, The results were viewed as being consistent with the known parameters affecting generalization gradients.     

Seeking Emergence Through Temporal Analysis of Collaborative-Group Discourse: A Complex-Systems Approach

Abstract

Research around problem solving in collaborative groups has made progress, but several conceptual and methodological issues remain. These issues include the appropriate choices of units of analysis; the ability of current theoretical sets of macrocognition codes to capture group dynamics; detection and identification of potentially emergent phenomena within groups; and the extent to which multiple dynamics are integral to understanding groups. Using data from a complex engineering challenge, we applied methods drawn from complex-systems analysis to offer insight into each of these issues, showing the need for multiple dimensions when studying group dynamics and highlighting methodological difficulties when dealing with emergent phenomena. We suggest future research to improve the understanding of the complex dynamics of collaborative groups.     

The perceived benefits and problems associated with teaching activities undertaken by doctoral students

Postgraduate students involved in delivering undergraduate teaching while working toward a research degree are known as graduate teaching assistants (GTAs). This study focused upon the problems and benefits arising from this dual role as researchers and teachers, as perceived by GTAs at the University of Cambridge. To this end, GTAs at Cambridge were invited to participate in an online survey (n?=?153). Teaching is seen to offer a wide range of benefits to GTAs, including benefits to the GTAs’ own research, transferable skills development, career development and teaching skills. Time pressures emerged as the principal problem associated with the role. The data are consistent with findings from previous studies, while also providing further detail about the nature of the benefits and problems. In particular, additional insights are offered relating to benefits and problems associated with different teaching activities, and disciplinary differences.     

Understanding adult education in community contexts: A critical realist perspective

Third-sector community organisations are important sites for learning, especially for the most excluded groups in society. However, scant attention has been paid to the various factors shaping educational provision in community contexts, and how these interact to shape the provision available to marginalised populations. This article presents new evidence addressing this gap, through drawing on interview data from practitioners working in the UK homelessness sector. It identifies a range of factors shaping educational provision in these community contexts. These are: service user need and demand; staff roles and capacity; organisational purpose and structures; national policies; support from other adult education providers; non-governmental finance; and volunteers. With some modification, and placed within an overarching critical realist framework, it is argued that these findings are consistent with Boeren’s comprehensive lifelong learning participation model. The article concludes that so long as government policy and related funding continues to ignore and fails to support educational provision in these settings, it will remain piecemeal and highly contingent on the contribution of volunteers and short-term funding.     

True-False Testing on Trial: Guilty as Charged or Falsely Accused?

Although widely used, the true-false test is often regarded as a superficial or even harmful test, one that lacks the pedagogical efficacy of more substantive tests (e.g., cued-recall or short-answer tests). Such charges, however, lack conclusive evidence and may, in some cases, be false. Across four experiments, we investigated how true-false testing of studied passages (e.g., on Yellowstone National Park) might enhance—or be optimized to enhance—performance on subsequent cued-recall tests. In Experiments 1–2, relative to control performance that did not benefit from any additional exposure, we found that (a) the evaluation of true statements enhanced the recall of tested (but not related) content and that (b) the evaluation of false statements enhanced the recall of related (but not tested) content, a differential pattern of benefits that did not depend on the syntactic structure of the test items. Moreover, when competitive clauses were embedded within the true-false items of Experiment 3 (e.g., True or false? Castle Geyser (not Steamboat Geyser) is the tallest geyser), we found that the evaluation of both types of statements enhanced the recall of both types of content. Finally, in Experiment 4, these holistic benefits proved robust to a retention interval of 48 h and were comparable with the benefits of a restudy condition in which learners restudied all of the propositions that could have been retrieved in the evaluation of the true-false items. Accordingly, although it was not uncommon for participants to misremember information as a consequence of true-false practice, our findings broadly indicate that, especially when carefully constructed, true-false tests can elicit beneficial, not superficial, processes that belie their poor reputation.

     

An assessment matrix for library makerspaces

The emergence of maker culture has led to an increase of makerspaces across a variety of educational organizations, including public libraries. These makerspaces provide library patrons with new opportunities to learn and create through exploration, creation, and play. However, as the number of library makerspaces grows, so does the need for assessing learning in those same spaces. There is a small amount of research completed on assessing learning of makerspaces in public libraries. The researchers in this study examine patron use of a library makerspace through a theoretical framework based on modern assessment research. Soon after the study began, it was necessary to rethink the original research questions and methods in order to better understand how assessment could be effectively implemented. Findings include determining the scope of library makerspace participants and their assessment needs, potential assessments that can address those needs, and design implications for assessments in library makerspaces.     

Die Umwegrentabilit?t einer Hochschule am Beispiel der FH JOANNEUM Campus Kapfenberg

Hochschulen verursachen nicht nur Kosten, sondern generieren auch einen erheblichen Nutzen, da sie Geld- und Güterstr?me zwischen der ?ffentlichen Hand, Privatpersonen und Unternehmen in Gang setzen. Daraus resultieren tangible (in Geldwerten messbare) und intangible (nicht in Geldwerten messbare) Effekte, die durch den Betrieb einer Hochschule entstehen. Diese Auswirkungen wurden für den Standort Kapfenberg der FH JOANNEUM erhoben. Aus der durchgeführten Analyse ergeben sich folgende Effekte: aus kurzfristiger Sichtweise flie?en j?hrlich fast 3,0 Mio. € der Region Bruck/Mur-Kapfenberg zu, der mittelfristig in der Region verbleibende Kaufkraftanteil betr?gt über 2,0 Mio. € und aus langfristiger Perspektive werden durch das Bestehen der FH JOANNEUM Campus Kapfenberg fast 3,6 Mio. € an zus?tzlichem Einkommen in der Region Bruck/Mur-Kapfenberg induziert. Daneben entstehen durch die Existenz einer Hochschule auch noch positive Effekte für eine Region, die nicht eindeutig quantifizierbar sind.
