The existence of dyslexia without severe literacy problems     

T.?R.?MilesEmail author  T.?J.?Wheeler  M.?N.?Haslum 《Annals of dyslexia》2003,53(1):340-354

This paper is concerned with those who display positive indicators on tests for dyslexia but seemingly do not have any severe literacy problems. A case study is presented by way of illustration. On the basis of data from the British Births Cohort Study (12,905 10-year-old children), it was found that some seemingly normal achievers who showed signs of dyslexia (N=422) obtained different results on five measures associated with dyslexia than did other normal achievers without such signs (N=4,998). The measures used were: underachievement at word recognition; and underachievement at spelling, reading comprehension, pseudoword reading, and mathematics. The proportion of boys to girls in the groups was also noted. It is suggested that these were cases of mild dyslexia, who, on the basis simply of reading and spelling tests, might escape detection. The consequences for the concept of dyslexia are discussed, and it is suggested that the needs of dyslexics with only mild literacy problems should not be overlooked.  相似文献   

Effects of segmenting,signalling, and weeding on learning from educational video     

Mohamed Ibrahim  Carmen M. Greenwood  Denna Wheeler 《Learning, Media and Technology》2012,37(3):220-235

Informed by the cognitive theory of multimedia learning, this study examined the effects of three multimedia design principles on undergraduate students' learning outcomes and perceived learning difficulty in the context of learning entomology from an educational video. These principles included segmenting the video into smaller units, signalling to direct students' attention to relevant information, and weeding to remove any non-essential content (SSW). It was hypothesized that the SSW treatment would decrease perceived learning difficulty and facilitate the transfer of knowledge and the structural knowledge acquisition. Results of the study demonstrate that participants in the SSW group outperformed the non-SSW group on the tests of knowledge transfer and structural knowledge acquisition and reported lower levels of learning difficulty. These findings support the use of SSW to help novice learners organize and integrate knowledge from complex, dynamic audio-visual media like video.  相似文献   

World of work on TV: Ethnic and sex representation in TV drama     

John F. Seggar  Penny Wheeler 《广播与电子媒介杂志》2013,57(2):201-214

On the pages which follow, authors Seggar and Wheeler explore the increasing use of minority group members in network television programming. They focus on a sample period in 1971 to show variances in dramatic portrayals of minority versus white American roles. Dr. Seggar received his Ph.D. from Kentucky in 1968 and has since taught at Brigham Young University where he is now associate professor of sociology. Ms. Wheeler received her MA in sociology at BYU in 1971. An earlier version of this paper was first presented at the 1972 convention of the Association for Education in Journalism.  相似文献   

Teacher perceptions of an online tutoring program for elementary mathematics     

Patti Whetstone  Mari Wheeler Flake 《Educational Media International》2013,50(1):79-90

This study explores elementary teacher perceptions related to the implementation of an online tutoring program. Teachers were surveyed regarding factors that affected use of the online tutoring program as a supplement to mathematics instruction. Results indicated that teachers overwhelmingly reported positive views of the training and support opportunities provided, as well as confidence in their level of knowledge and the ease of use of the program. Teachers also indicated strong support of the mathematical content and instructional value of the program. Each of these factors increases the likelihood that online tutoring programs such as the one implemented in this study will continue to be used among teachers as a supplement to mathematics instruction.  相似文献

Effect of the addition of hydroxyl-terminated polydimethylsiloxane to TEOS-based stone consolidants     

Ramón Zárraga  Jorge Cervantes  Carmen Salazar-Hernandez  George Wheeler 《Journal of Cultural Heritage》2010,11(2):138-144

Hybrid stone consolidants prepared from tetraethoxysilane (TEOS) and α,ω-hydroxyl-terminated polydimethylsiloxane (PDMS-OH) have been considered as one of the most promising approaches to improve the effectiveness of traditional alkoxysilane-based formulations. They have emerged as response to the negative reports commonly found in the literature: the resulting silica gel phase (SiO₂) tends to develop fractures and fissures inside the stone as the gel shrinks during the drying stage. In this work, we employed SEM, solid-state ²⁹Si NMR spectroscopy and compressive tests to characterize SiO₂-PDMS hybrid gels. We report the morphological characteristics exhibited by gels prepared in vitro and in situ. It was found an appreciable reduction of gel fracture for hybrids prepared from 5% w/w of PDMS. As TEOS polycondenses, PDMS-OH is chemically incorporated into the gel matrix via Si-O-Si bonds. The inclusion of these elastic chains provides the necessary flexibility to resist the stress imposed by capillary pressure. Additionally, an important hydrophobic character is imparted to the stone.  相似文献
