A single-subject alternating treatment design was used to investigate the extent to which a specialized dyslexia font, OpenDyslexic, impacted reading rate or accuracy compared to two commonly used fonts when used with elementary students identified as having dyslexia. OpenDyslexic was compared to Arial and Times New Roman in three reading tasks: (a) letter naming, (b) word reading, and (c) nonsense word reading. Data were analyzed through visual analysis and improvement rate difference, a nonparametric measure of nonoverlap for comparing treatments. Results from this alternating treatment experiment show no improvement in reading rate or accuracy for individual students with dyslexia, as well as the group as a whole. While some students commented that the font was “new” or “different”, none of the participants reported preferring to read material presented in that font. These results indicate there may be no benefit for translating print materials to this font. 相似文献

Over the past decade, there has been a strong national push to increase minority students’ positive attitudes towards STEM-related careers. However, despite this focus, minority students have remained underrepresented in these fields. Some researchers have directed their attention towards improving the STEM pipeline which carries students through our educational system and into STEM careers. Previous research has shown that expectancy-value theory (EVT) is useful for examining the short-term as well as long-term academic motivations and intentions of elementary age minority students. These findings provide insights into ways we may be able to potentially “patch” particular STEM pipeline leaks. In the current study, we advance this research by using EVT as a framework to examine the STEM attitudes of young students directly. We hypothesize that students’ academic-related expectancies for success and subjective task values will be associated with an increase in STEM attitudes. Data for this study was gathered over the course of a large-scale computing intervention which sought to increase students’ STEM interest. This computing intervention took place in an urban elementary school district located within the southeastern USA. Results from this study indicate that both intrinsic values and utility values predict students’ STEM attitudes but they influence attitudes related to the various dimensions of STEM differently. These findings demonstrate that EVT provides a useful framework, which can be integrated into future computing interventions, to help encourage positive STEM attitudes in young children, thus increasing the internal pressure (or flow) within the STEM pipeline. 相似文献

Young adults are disproportionately affected by negative sexual health outcomes, such as sexually transmitted infections. One strategy for reducing such negative outcomes involves the use of comprehensive sexual health education. As comprehensive sexual health education programmes are adopted, there is a need to evaluate the messaging approaches that might best connect with young people. Sex-positive approaches, which describe sex as a healthy practice and personal choice, are becoming popular, but whether this strategy works has not been tested from a message design perspective. This study examines the reactions of young adults to sex-positive or sex-negative messages, framed as a gain or loss, designed for a text message-based intervention. Participants quantitatively evaluated 24 messages on their mobile phones. Gain frames were preferred over loss frames, and sex-positive messages were rated as more believable and persuasive. An interaction between the two concepts was also found. Results highlight how sex-positive messages that focus on the benefits of certain behaviours tend to resonate better with young adults. Implications for health educators and practitioners are discussed. 相似文献

Over the past 20 years, the USA has seen more than its fair share of controversy with respect to education about sexuality, sex and intimate relationships. Attention has focused on content (abstinence-only vs. comprehensive instruction), delivery (by teachers, parents, health professionals or community educators) and context (within school and beyond). In recognition of this fact, Sex Education invited the development of a virtual special issue comprising a sample of its most impactful papers on these and related topics. The 2016 Presidential election results and recent legislative action in the USA point to the importance of thinking broadly about teaching and learning about sexuality inside and outside of schools and of considering sexuality as it intersects with categories of difference, privilege and penalty, including ability, age, immigration, race, gender and class. This paper, developed as an introduction to the virtual special issue, opens with a discussion of the journal’s contributions to the ongoing discussion of pleasure and desire in sexuality education. From there, we turn to the question of what is possible given the material and ideological conditions of schooling and then to opportunities for teachers and learners outside the conventional classroom. We follow with a discussion of the place of intersectional analyses in sexuality education research, and conclude with some thoughts on sexuality education research at this political moment. 相似文献

My avatar,my self: Virtual harm and attachment 总被引:1,自引:0,他引:1
Jessica Wolfendale 《Ethics and Information Technology》2007,9(2):111-119
Multi-user online environments involve millions of participants world-wide. In these online communities participants can use
their online personas – avatars – to chat, fight, make friends, have sex, kill monsters and even get married. Unfortunately
participants can also use their avatars to stalk, kill, sexually assault, steal from and torture each other. Despite attempts
to minimise the likelihood of interpersonal virtual harm, programmers cannot remove all possibility of online deviant behaviour.
Participants are often greatly distressed when their avatars are harmed by other participants’ malicious actions, yet there
is a tendency in the literature on this topic to dismiss such distress as evidence of too great an involvement in and identification
with the online character. In this paper I argue that this dismissal of virtual harm is based on a set of false assumptions
about the nature of avatar attachment and its relation to genuine moral harm. I argue that we cannot dismiss avatar attachment
as morally insignificant without being forced to also dismiss other, more acceptable, forms of attachment such as attachment
to possessions, people and cultural objects and communities. Arguments against according moral significance to virtual harm
fail because they do not reflect participants’ and programmers’ experiences and expectations of virtual communities and they
have the unintended consequence of failing to grant significance to attachments that we take for granted, morally speaking.
Avatar attachment is expressive of identity and self-conception and should therefore be accorded the moral significance we
give to real-life attachments that play a similar role.

Individuals with autism spectrum disorder (ASD) show differences in face processing abilities from early in development. To examine whether these differences reflect an atypical versus delayed developmental trajectory, neural responses to familiar and unfamiliar faces in twenty-four 18- to 47-month-old children with ASD were compared with responses of thirty-two 12- to 30-month-old typically developing children. Results of 2 experiments revealed that neural responses to faces in children with ASD resembled those observed in younger typically developing children, suggesting delayed development. Electrophysiological responses to faces were also related to parent report of adaptive social behaviors for both children with ASD and typical development. Slower development of the face processing system in ASD may be related to reduced self-directed "expected" experience with faces in early development. 相似文献

Many schools are beginning to implement multi-tier response to intervention (RTI) models for the prevention of reading difficulties and to assist in the identification of students with learning disabilities (LD). The present study was part of our larger ongoing longitudinal RTI investigation within the Florida Learning Disabilities Center grant. This study used a longitudinal correlational design, conducted in 7 ethnically and socio-economically diverse schools. We observed reading instruction in 20 classrooms, examined response rates to kindergarten Tier 1 instruction, and predicted students' first grade reading performance based upon kindergarten growth and end of year reading performance (n = 203). Teachers followed an explicit core reading program and overall, classroom instruction was rated as effective. Results indicate that controlling for students' end of kindergarten reading, their growth across kindergarten on a variety of language and literacy measures suppressed predictions of first grade performance. Specifically, the steeper the students' trajectory to a satisfactory outcome, the less likely they were to demonstrate good performance in first grade. Implications for future research and RTI implementation are discussed. 相似文献

This article summarizes the current knowledge of response‐to‐intervention (RTI) models in preschool settings, with an emphasis on evaluating the strengths and weaknesses of our current research base. Particular attention is given to the unique challenges of high‐risk preschool settings. Presently, sufficient empirical support exists to begin establishing tiered intervention systems and building teacher capacity. Lacking, however, are valid and reliable assessment tools and insufficiently trained personnel to support a data‐based decision‐model within high‐risk preschools. We conclude that organizational development should focus on building teacher capacity, establishing high‐quality classroom instruction, and planning for sustainable programs, with adoption of a full RTI service delivery model serving as a long‐range aspirational goal. © 2011 Wiley Periodicals, Inc. 相似文献

The development of interest in reading and its relationship to reading ability was examined longitudinally in 117 children in Grades 1–3. Interest in reading was measured by eight items from the Elementary Reading Attitude Survey. Less able readers had lower interest in reading, but their development was parallel to that of more able readers. Interest in reading in Grade 1 was weakly correlated with Grade 3 reading ability, but correlations were lower for interest measured in Grades 2 and 3. Hierarchical regression analyses indicated weak and inconsistent effects of reading interest on reading ability after controlling general cognitive ability, SES, phonological awareness and naming speed. It is concluded that interest in reading has only a weak relationship to reading ability in the early elementary years, and that much of that relationship overlaps with the effects of other more powerful predictors. 相似文献

Despite the many benefits of involving undergraduates in research and the growing number of undergraduate research programs,
few scholars have investigated the factors that affect faculty members’ decisions to involve undergraduates in their research
projects. We investigated the individual factors and institutional contexts that predict faculty members’ likelihood of engaging
undergraduates in their research project(s). Using data from the Higher Education Research Institute’s 2007–2008 Faculty Survey,
we employ hierarchical generalized linear modeling to analyze data from 4,832 science, technology, engineering, and mathematics
(STEM) faculty across 194 institutions to examine how organizational citizenship behavior theory and social exchange theory
relate to mentoring students in research. Key findings show that faculty who work in the life sciences and those who receive
government funding for their research are more likely to involve undergraduates in their research project(s). In addition,
faculty at liberal arts or historically Black colleges are significantly more likely to involve undergraduate students in
research. Implications for advancing undergraduate research opportunities are discussed. 相似文献
