Developmental dyslexia: Is it different from other forms of reading disability?     

P. G. Aaron 《Annals of dyslexia》1987,37(1):109-125

A controversy whether developmental dyslexia is qualitatively different from other forms of reading disability has existed among reading specialists for many years. In the present study, the hypothesis that the etiology of dyslexia is different from that of other forms of reading disability because of differences in the components that malfunction was tested. A number of studies have shown that the two components that contribute to a large proportion of variance in reading are decoding and comprehension. It is, therefore, possible that a breakdown of different components could lead to different forms of disabilities. College students who were poor readers were assigned to two groups on the basis of their IQ. Conforming to the traditional criterion of dyslexia, those who had an IQ of 95 and above were considered as dyslexic. Those who had an IQ of 85 or below were placed in the Nonspecific Reading-Disabled group. These two groups of poor readers and a group of normal readers were administered a large number of reading-related tests. It was found that the two reading-disabled groups differed from each other in six of the seven areas assessed. There was very little overlap of scores between the two groups in these areas. The results were interpreted to suggest that poor decoding skill is the etiology of developmental dyslexia and that it differs from other forms of reading disability which are caused by generalized cognitive deficits.  相似文献   

Field-based professional development of teachers engaged in distance education: experiences from the Arctic     

George Veletsianos  Aaron Doering  Jeni Henrickson 《Distance Education》2012,33(1):45-59

We examine the experiences of five teachers who traveled with a team of educators, scientists, and explorers on circumpolar Arctic expeditions to deliver adventure learning (AL) programs to K–12 students at a distance. Results highlight the personal and professional impacts this opportunity had on teachers, including their empowering, fulfilling, and mentally exhausting experiences while assisting in delivering distance education to students worldwide. The article concludes with a discussion of issues to consider in the development of similar programs.  相似文献   

Using Food Science Demonstrations to Engage Students of All Ages in Science,Technology, Engineering,and Mathematics (STEM)     

Shelly J. Schmidt  Dawn M. Bohn  Aaron J. Rasmussen  Elizabeth A. Sutherland 《Journal of Food Science Education》2012,11(2):16-22

Abstract: The overarching goal of the Science, Technology, Engineering, and Mathematics (STEM) Education Initiative is to foster effective STEM teaching and learning throughout the educational system at the local, state, and national levels, thereby producing science literate citizens and a capable STEM workforce. To contribute to achieving this goal, we have assembled six food science demonstrations for use at all educational levels and have presented these lessons to students at the elementary through higher education levels. The focus of this article is to share these food science demonstrations and our experiences using them so that others can use them for engaging students in STEM disciplines, through food science, at any educational level. Featured demonstrations include: (1) liquid nitrogen ice cream: a matter of changing phases, (2) seeing our senses work together, (3) whipping up the cream, (4) milk versus dark: what is the difference?, (5) counting calories by burning them, and (6) culinary spherification: the wonders of cross‐linking. Overall, our experience with using these demonstrations has been very positive. Students appear engaged in the learning process and love to consume the demonstration end products. Downloadable handouts containing demonstration details for each demonstration are available as supporting information.  相似文献   

Enhancing preschool children's vocabulary: Effects of teacher talk before,during and after shared reading     

Jorge E. Gonzalez  Sharolyn Pollard-Durodola  Deborah C. Simmons  Aaron B. Taylor  Matthew J. Davis  Melissa Fogarty  Leslie Simmons 《Early childhood research quarterly》2014

This observational study analyzed patterns of teacher extratextual talk as it occurs before, during, and after reading books to children, and the frequency and duration of teacher questioning by type (label, define, associate) on preschoolers’ receptive and expressive vocabulary knowledge. Over the course of 18 weeks, 13 teachers and 100 children participated in ninety 20-min small-group sessions of teacher-guided shared reading instruction. Teachers’ reading instruction was examined through videotaped observations using the Multi-Option Observation System for Experimental Studies (MOOSES™; Tapp, Wehby, & Ellis, 1995). Two findings, in particular, yielded relevant educational and theoretical implications. First, time spent after reading was significantly related to expressive vocabulary. However, question timing did not seem to matter in terms of receptive vocabulary outcomes. Second, duration of teacher association questioning was significantly related to receptive vocabulary outcomes while both frequency and duration of teacher vocabulary-related association-level questioning were related to expressive vocabulary. For receptive vocabulary, both vocabulary- and comprehension-related association-level questioning mattered. These findings complement the body of work demonstrating that engaging children in interactive shared reading that elicits their active participation is related to meaningful gains in children's language and literacy growth. Limitations of the study and directions for future research are discussed.  相似文献

Coverage of Methamphetamine in GLBT Newspapers     

Joseph Schwartz  Aaron Willis 《Mass Communication and Society》2013,16(1):30-47

Research demonstrates that methamphetamine is a serious problem in gay communities. This study examined the framing of methamphetamine in nine gay, lesbian, bisexual, and transgender (GLBT) newspapers. Results showed that methamphetamine was framed as a “gay problem,” that sexual health and solutions frames were prevalent, and that GLBT newspapers covered methamphetamine in a way that is similar to how they covered AIDS in the 1980s. Implications for health campaigns are discussed.  相似文献   

“You Don't Play,You Volunteer”: Narrative Public Memory Construction in Medal of Honor: Rising Sun     

Aaron Hess 《Critical Studies in Media Communication》2013,30(4):339-356

Narrative and ludological analysis suggests that Electronic Arts’ Medal of Honor: Rising Sun constructs a narrative of World War II that selectively retells history and constructs an Orientalist representation of the Japanese Empire. The gaming environment exists as an interactive museum that immerses gamers into history so that they experience warfare in their homes. Combining newsreels, fictional letters from home, and interviews with veterans of the “Good War,” Medal of Honor: Rising Sun retells a history that omits details of Japanese internment or atomic weapons. The intertwined themes of personal revenge for the loss of a family member and historical revenge for the attack on Pearl Harbor guide gamers through an “educational” experience of the war. Finally, its failure to simulate violence means that Medal of Honor: Rising Sun invites a critical blindness to commemorating war.  相似文献

Examining the complexities of measuring effectiveness of online counselling for young people using routine evaluation data     

Aaron Sefi  Terry Hanley 《Pastoral Care in Education》2013,31(1):49-64

As mental health services for young people develop, the need for evaluation and audit to justify expenditure follows suit. Counselling is being provided in more and more schools and community settings across the country, and there is an increasing focus on evidence-based funding. Practice-based evidence has an important role to play in fulfilling this requirement, and there are calls for a single outcome measure to be utilised across services. The emerging frontier of online support is receiving steadily greater attention, but as yet it has had little attention with regards to its effectiveness. An existing routine evaluation and outcome measure (Young Person’s Clinical Outcome Measures in Routine Evaluation) was incorporated within other routine evaluation systems within an online support service for young people (Kooth). The findings have been examined, with a view to recommending most suitable evaluation tools for this medium. Initial data suggest that the online service, when compared with equivalent face-to-face data, attracts a wide range of needs and levels of distress, with a high proportion of complex needs presented. Such findings may also reflect the complex nature of the support needs for the client group in question. Capturing appropriately rich data using a range of qualitative and quantitative measures that account for the complex online environment and client group needs to be carefully considered.  相似文献   

Careers in aging: how job-seekers search for and how employers advertise positions in aging-related markets     

Tina M. Kruger  Leanne J. Clark-Shirley  Marc Aaron Guest 《Educational gerontology》2013,39(7):483-494

Given its rapidly-aging population, the U.S. needs a workforce that is informed about and capable of meeting the diverse needs of older adults. Students pursing gerontology education may feel unsure of career opportunities as they enter a job market with traditionally clearly-defined disciplinary backgrounds. The goal of this study was to explore how people currently employed in an aging-related job searched for positions, and how this compared to phrasing used by employers to advertise job openings across several aging-related fields. A web-based survey was administered to employees in aging-related positions, and a search of four job-seeking websites to collect and analyze aging-related job postings was conducted. Most (63%) currently working in the field of aging reported finding their jobs through referral from a friend/colleague or through job search sites or job boards. Out of 493 relevant job postings identified, only 175 of the postings (35%), preferred or required applicants to have some type of aging-related knowledge, skills, training, or prior experience. There may be consequences to not specifically recruiting applicants with aging-related backgrounds: job seekers with qualifications in aging may look for other positions that expressly call for their specialized skills or knowledge, and quality of services and care may be different when provided by persons without such training.  相似文献
