Effects of stress controllability,immunization, and therapy on the subsequent defeat of colony intruders

Three experiments investigated the influence that various stress-controllability manipulations had on the defensive behaviors of rats when they were subsequently tested as intruders in previously established, aggressive colonies of conspecifics. In Experiment 1, naive subjects that had received a session of 80 shocks in a tube showed an enhanced series of defensive responses and received more bites than did a group of restrained nonshocked rats as colony intruders 24 h later. These two measures were also found to be positively correlated within each group. In Experiment 2, a group that was given 80 yoked inescapable shocks, in contrast to a group that had wheel-turn escape training and a restrained nonshocked control group, displayed more defeat and was bitten more frequently when tested as intruders on the following day. In Experiment 3, 60 trials of wheel-turn escape training were given 4 h prior to (i.e., immunization) or after (i.e., therapy) a session of 60 inescapable tube shocks. During resident-intruder testing 24 h later, both of these groups showed less defeat and received fewer bites than did an inescapably preshocked group but did not differ from a restrained nonshocked control group. These findings clearly indicate that stress controllability alters species-typical defensive responses, and their implications concerning other learned helplessness effects and interpretations are discussed.     

The fog of online learning

The authors recognized a close similarity between practices used in online genealogy research and those common in online education. Uses of a popular online database service were examined within a peer instruction community dedicated to researching a family history topic. Three community subgroups were divided into leaders, who base their work on external sources, and followers who copy the leaders’ conclusions. The accuracy and error levels of the 21 family trees produced by these researchers were calculated in relation to data obtained from offline archives. The trees created in the online process all contained flawed details and invalid conclusions due to practices similar to those of massive open online courses. The inconsistent reliability of the online approaches is discussed in terms of the ‘fog’ that descends upon knowledge when facts are distorted by academic jargon, disciplinary trends, and institutional priorities, and which increases with its transmission to others by non-experts.     

The Choice Architecture of School Choice Websites

Abstract

We conducted a randomized factorial experiment to determine how displaying school information to parents in different ways affects what schools they choose for their children in a hypothetical school district. In a sample of 3,500 low-income parents of school-aged children, a small design manipulation, such as changing the default order in which schools were presented, induced meaningful changes in the types of schools selected. Other design choices such as using icons to represent data, instead of graphs or just numbers, or presenting concise summaries instead of detailed displays, also led parents to choose schools with higher academic performance. We also examined effects on parents’ understanding of the information and their self-reported satisfaction and ease of use. In some cases, there were trade-offs. For example, representing data using only numbers maximized understanding, but adding graphs maximized satisfaction at the expense of understanding.     

The structure of imagery.

Children's drawings of objects about to be moved in space (anticipatory images) were studied in relation to their judgments about Euclidean spatial relations. Tasks assessing Euclidean geometric operations were administered to 102 girsl between the ages of 4 and 13 years. 5 operative levels resulted: (a) failure on all operations tasks, (b) success on conservation of length, (c) success on conservation and 1-dimensional measurement, (d) success on the latter 2 tasks plus measurement in 2 dimensions, and (e) success on the latter 3 tasks and coordination of internal and external reference frames. The same children performed on 6 imaginal tasks involving movements of objects. Results confirmed several theoretical expectations: (a) children who were unable to measure had difficulty imaging successive positions for 1-dimensional movement; (b) children who were unable to coordinate a point in space by reference to 2 axes were unable to draw states of movement correctly for 2-dimensional movement; (c) children's errors in drawing successive positions of moving objects were related to the structure of operations at the lower levels; and (d) the coordination of object positions over successive states was dependent on the ability to measure from an external frame. The results were interpreted as support for Piaget and Inhelder's theory of imagery development.     

Paul F-Brandwein 2004 Lecture: Regarding the Ecology of Science Education: Connections to Environmental and Distance Education

Paul F-Brandwein was a visionary who looked at education broadly. He left us with an insightful view of the ecology of education in which he identified three ecological systems: school–family–community, postsecondary, and cultural. The first part of this lecture, by Dean B. Bennett, examines Brandwein's ideas related to environmental education and explores the relationship of environmental education with science teaching in the K-12 school–family–community ecosystem. Focusing particularly on the middle-secondary level, evidence suggests that the goals of environmental education, since their emergence in the late 1960s, are today strongly evident in science curricula, instructional resources, educational assessment, and teacher education. But the author points out that more must be done and provides some fundamental suggestions. The second part of the lecture, by Sheila K. Bennett, examines the role of distance education in the teaching of science in the postsecondary ecosystem and addresses its value as a viable tool in promoting scientific literacy. The lecture focuses on a successful statewide, interdisciplinary laboratory science course delivered by interactive television, the Internet, and computer network. Now in its ninth year, the course reflects Brandwein's thinking about effective classroom teaching and is based on national standards for scientific literacy.     

From PSAs to reel communities: exploring the sounds and silences of urban youth mobilizing digital media production

ABSTRACT

Amplified by a global political climate of fear, oppression, and increased nationalism, this article examines how U.S. secondary students in a digital media elective course used multimodal composition, and video production in particular, as a nexus of ‘participatory politics.’ By partnering theories of multiliterate expression with youth civic engagement, it offers new understandings into how urban youth use digital media production to leverage school-based social action. Refracted through a mediated discourse analysis lens, and with a particular focus on sound as a modal resource for design, findings suggest that youth used media production and semiotic sense-making to simultaneously enliven community action as well as shield students from personal histories of trauma. By engaging in the process of digital media production, as this article suggests, students cultivated new core practices of civic interaction and local engagement by amplifying injustice.     

White Counselors' Conceptualization of Privilege and Oppression: Implications for Counselor Training

The authors in this qualitative study explored how White counselors define and experience privilege and oppression. Specifically, 2 research questions were addressed in semistructured interviews with 8 counselors: How do White counselors conceptualize privilege and oppression as separate but related constructs= and What experiences do White counselors generally describe concerning privilege and oppression? The authors present a research model that represents the factors that contribute to changes in the conceptualization and awareness of privilege and oppression and the way that these changes come about. Implications for counselor training are discussed.     

Enhancing the contribution of visual methods to inclusive education

This paper examines the use of visual methods in studies of inclusive education. Visual methods have been applied to/with pupils with special educational needs (SEN) in the past but the application has tended to be outside rather than inside schools. We argue that understanding contextual reflexivity is important if visual methods are to be successfully adapted to meet the needs of inclusive research. A case study is used to provide an insight into the strengths, weaknesses and difficulties of mixed method visual research. The final section of the paper explores potential applications, strategies and techniques for including visual methods in inclusivity research.     

Developing and Validating a Novel Anonymous Method for Matching Longitudinal School-Based Data

Prospective longitudinal data collection is an important way for researchers and evaluators to assess change. In school-based settings, for low-risk and/or likely-beneficial interventions or surveys, data quality and ethical standards are both arguably stronger when using a waiver of parental consent—but doing so often requires the use of anonymous data collection methods. The standard solution to this problem has been the use of a self-generated identification code. However, such codes often incorporate personalized elements (e.g., birth month, middle initial) that, even when meeting the technical standard for anonymity, may raise concerns among both youth participants and their parents, potentially altering willingness to participate, response quality, or generating outrage. There may be value, therefore, in developing a self-generated identification code and matching approach that not only is technically anonymous but also appears anonymous to a research-naive individual. This article provides a proof of concept for a novel matching approach for school-based longitudinal data collection that potentially accomplishes this goal.
