Amid rising concerns about “fake news,” efforts have emerged to explain the spread and impact of misinformation on youth civic engagement. These efforts have focused primarily on the role of social media in exposing youth to factually inaccurate civic information and the factors that influence the ability to discern the accuracy of such information. A less explored aspect has been the impact of the rise of “outrage language,” defined as language that evokes strong emotional responses (e.g., fear, anger, disgust) that communications scholars have documented as playing a larger role in political discourse over the past few decades (Berry &; Sobieraj, 2014). This article draws on three recent studies of digital media and youth civic engagement to discuss (a) the role of participatory media in exposing youth to outrage language in civic discourse, (b) the challenges of balancing attention to the emotional and factual elements when participating in online civic discourse, and (c) how the development of online counterpublics through high school classrooms can help students create models of productive online discourse. The article concludes with suggestions for future research and educational interventions that address the challenges associated with outrage language. 相似文献

This article explores the use of classroom video as a tool for fostering productive discussions about teaching and learning. The setting for our research is a 2-year mathematics professional development program, based on the Problem-Solving Cycle model. This model relies on video from the teachers’ own classrooms and emphasizes creating a community in which members feel comfortable learning from video. We describe our experiences carrying out the Problem-Solving Cycle model, focusing on our use of video, our efforts to promote a supportive and analytical environment, and the ways in which teachers’ conversations around video developed over a 2-year period. 相似文献

How can the high school science enrollment of black students be increased? School and home counseling and classroom procedures could benefit from variables identified as predictors of science enrollment. The problem in this study was to identify a set of variables which characterize science course enrollment by black secondary students. The population consisted of a subsample of 3963 black high school seniors from The High School and Beyond 1980 Base-Year Survey. Using multiple linear regression, backward regression, and correlation analyses, the US Census regions and grades mostly As and Bs in English were found to be significant predictors of the number of science courses scheduled by black seniors. 相似文献

Modern retrieval test collections are built through a process called pooling in which only a sample of the entire document
set is judged for each topic. The idea behind pooling is to find enough relevant documents such that when unjudged documents
are assumed to be nonrelevant the resulting judgment set is sufficiently complete and unbiased. Yet a constant-size pool represents
an increasingly small percentage of the document set as document sets grow larger, and at some point the assumption of approximately
complete judgments must become invalid. This paper shows that the judgment sets produced by traditional pooling when the pools
are too small relative to the total document set size can be biased in that they favor relevant documents that contain topic
title words. This phenomenon is wholly dependent on the collection size and does not depend on the number of relevant documents
for a given topic. We show that the AQUAINT test collection constructed in the recent TREC 2005 workshop exhibits this biased
relevance set; it is likely that the test collections based on the much larger GOV2 document set also exhibit the bias. The
paper concludes with suggested modifications to traditional pooling and evaluation methodology that may allow very large reusable
test collections to be built.

Many physical educators in Canadian Atlantic provinces are forced to cope with large classes, inadequate facilities and equipment, and reductions in scheduled time for physical education classes. These factors seriously inhibit teachers' attempts to encourage their students to practice physically active lifestyles. In the following article our research focuses on how seven female physical educators negotiate compromises between their restrictive pedagogical environments and their goal of helping students to establish lifelong activity habits through promotion of fun in physical education class. 相似文献

Factitious disorder by proxy (FDP), historically known as Munchausen syndrome by proxy, is a diagnosis applied to parents
and other caregivers who intentionally feign, exaggerate, and/or induce illness or injury in a child to get attention from
health professionals and others. A review of the recent literature and our experience as consultants indicate clearly that
FDP has emerged in educational settings as well. Variants of educational FDP include parents of children with real or fabricated
physical disabilities who request excessive or unneeded school health services and parents who request extensive education-related
evaluations for children who do not demonstrate any educational need. If such cases continue to emerge, school districts will
be asked to test more students who do not have disabilities under the Individuals with Disabilities Education Act. Also, special
educational directors will be weighing the cost of providing unneeded testing and educational services against the cost of
defending themselves in litigation to prove that the testing and services are unnecessary. A table of guidelines is provided
for school and other personnel confronted with repeated requests for unwarranted special education services. Suggestions for
future research are included. 相似文献

Parental participation in schools has become a goal for many principals in light of theoretical and empirical work suggesting that increased school-parent interaction can result in significant educational benefits. This study examined the principal-parent relationship in three types of schools: those serving a homogeneous high-SES parent clientele, a heterogeneous middle-SES parent clientele, and a homogeneous low-SES parent clientele. The main question posed in this paper is whether the principal-parent relationship in schools with a heterogeneous parent clientele differs from the relationships in homogeneous schools, regardless of social class, or whether social class is the determining factor in the principal-parent relationship. Discriminant analysis of 250 elementary school principals indicated two significant functions: one according to the social class of the parents and the other according to the homogeneity of the parent clientele. The differences in the relationships, as suggested by the significant discriminating variables, are in the areas of parental involvement, the organization of parent groups, and principals' response strategies to this involvement. The results suggest how principals interact with different types of parents to capitalize on areas where parents can help without allowing excessive interference in the school's functioning. 相似文献
