The eye movements of 23 deaf subjects, ages 14 to 61 years, were recorded 30 times per second while the subjects watched four 2.5-minute captioned television programs. The eye movement data were analyzed to determine the percentage of time each subject actually looked at the captions on the screen. It was found that subjects gazed at the captions 84% of the time, at the video picture 14% of the time, and off the video 2% of the time. Age, sex, and educational level appeared to have little influence on time spent viewing captions. When caption speed increased from the slowest speed (100 words per minute, or wpm) to the fastest speed (180 wpm), mean percentage of time spent gazing at captions increased only from 82% to 86%. A distinctive characteristic of the data was the considerable variation from subject to subject and also within subjects (from video to video) in regard to percentage of time spent gazing at captions. 相似文献

Closed captions for television have become an important means of communication for hearing-impaired people. Yet, previous studies show that hearing-impaired people are very likely to have visual problems that may interfere with caption reading. In this study, the effect of reduced vision on caption reading is examined. Six hearing-impaired and 14 hearing subjects viewed segments of captioned movies on a 19-inch television screen at a distance of three meters. All of the subjects had normal vision. Their vision was blurred with plus lenses of five different strengths. The data show that caption reading is affected by relatively small amounts of blur. If a person has even a slight visual problem, the caption letters under normal television viewing conditions are too small for maximum reading performance. 相似文献

Caption rate and text reduction are factors that appear to affect the comprehension of captions by people who are deaf or hard of hearing. These 2 factors are confounded in everyday captioning; rate (in words per minute) is slowed by text reduction. In this study, caption rate and text reduction were manipulated independently in 2 experiments to assess any differential effects and possible benefits for comprehension by deaf and hard-of-hearing adults. Volunteers for the study included adults with a range of reading levels, self-reported hearing status, and different communication and language preferences. Results indicate that caption rate (at 130, 180, 230 words per minute) and text reduction (at 84%, 92%, and 100% original text) have different effects for different adult users, depending on hearing status, age, and reading level. In particular, reading level emerges as a dominant factor: more proficient readers show better comprehension than poor readers and are better able to benefit from caption rate and, to some extent, text reduction modifications. 相似文献

With rapid advances in digital technology, the broadcast television industry will soon be providing cinema-quality sound and video in the home. Given this technological advance, how should captions change to better serve consumers who are deaf or hard of hearing? To address this question, consumer preference data were collected from 207 deaf students and adults. Videodisc examples of various captioning feature combinations were used to obtain ratings from these consumers. Findings from multivariate conjoint analysis show that some current captioning features should be retained (white letters and speaker-dependent placement), while other features should be adopted (captioning in sentences and use of a clear or semitransparent background). These findings offer guidance to the captioning and television industries as they launch the digital television age. 相似文献

Two versions of a technical film, captioned at approximately 8th- and 11th-grade reading levels, were shown to 32 hearing-impaired college students. Fifteen of these students also received supplementary instruction from a teacher. Data from a comprehension test were analyzed with a four-factor experimental design to determine effects of instruction, level of captioning, test type (recall or recognition), and subject reading ability. Significant effects were found for instruction, test type, and reading ability. In addition, there was a significant three-way interaction between instruction, caption level, and reading ability. While both high and low reading groups benefited from instruction when students viewed 8th-grade level, modified captions, only the high reading group benefited from instruction when they viewed the 11th-grade level, original captions.This research was conducted in the course of an agreement with the U.S. Office of Education. 相似文献

One of the most frequently recurring themes in captioning is whether captions should be edited or verbatim. The authors report on the results of an eye-tracking study of captioning for deaf and hard of hearing viewers reading different types of captions. By examining eye movement patterns when these viewers were watching clips with verbatim, standard, and edited captions, the authors tested whether the three different caption styles were read differently by the study participants (N = 40): 9 deaf, 21 hard of hearing, and 10 hearing individuals. Interesting interaction effects for the proportion of dwell time and fixation count were observed. In terms of group differences, deaf participants differed from the other two groups only in the case of verbatim captions. The results are discussed with reference to classical reading studies, audiovisual translation, and a new concept of viewing speed. 相似文献

In this study, the reading comprehension of deaf children and adolescents in the Netherlands is examined along with their
word identification. The reading comprehension of 464 deaf students and the word identification of 504 deaf students between
6 and 20 years of age was examined. The results show the reading comprehension scores of deaf children to be far below the
scores of hearing children. On average, the deaf subjects scored at a level equivalent to a hearing child in the first grade.
The word identification scores of the deaf children, however, were almost equivalent to the scores of hearing children. Although
reading comprehension and word identification appear to be related, this relation does not completely explain the comprehension
difficulties encountered by deaf children. Additional factors are required to explain deaf children’s difficulties with reading
comprehension. 相似文献

This paper reports the results of the National Survey of Accommodations and Alternate Assessments for Students who are Deaf or Hard of Hearing in the United States (National Survey). This study focused on the use of accommodations and alternate assessments in statewide assessments used with students who are deaf or hard of hearing. A total of 258 participants responded to the survey, including 32 representing schools for the deaf, 168 from districtwide/school programs, and 58 from mainstreamed settings. These schools and programs served a total of nearly 12,000 students who are deaf or hard of hearing nationwide. The most prevalent accommodations used in 2003-2004 statewide standardized assessments in mathematics and reading were extended time, an interpreter for directions, and a separate room for test administration. Read aloud and signed question-response accommodations were often prevalent, used more often for mathematics than in reading assessments. Participants from mainstreamed settings reported a more frequent use of accommodations than those in schools for the deaf or districtwide/school programs. In contrast, schools for the deaf were most likely to have students participate in alternate assessments. The top three alternate assessment formats used across all settings were out-of-level testing, work samples, and portfolios. Using the National Survey results as a starting point, future research will need to investigate the validity of accommodations used with students who are deaf or hard of hearing. In the context of the No Child Left Behind Act of 2001 accountability policies, the accommodations and alternate assessment formats used with students who are deaf or hard of hearing may result in restrictions in how scores are integrated into state accountability frameworks. 相似文献

The study examined how computer technology is used, modeled, and taught in programs that prepare future teachers of students who are deaf or hard of hearing. Data were collected through two self-reported survey instruments sent to participants from two different groups: (a) deaf education faculty (n = 233) and (b) administrators of programs serving students who are deaf or hard of hearing (n = 100). Among the faculty who responded to the survey, 99% said they used computers and printers for instruction during class, 84% said they used VCRs for instruction during class, and 56% said they used video cameras for instruction during class. The information that was reported on how technology was being used for instruction and how its use was being taught to students in deaf education teacher preparation programs indicates that the need persists for integration of technology into these programs. A need likewise continues for improved instructional strategies relative to computers and technology. 相似文献

A nationwide study was conducted to examine the relationship between prelingually deaf adolescents' reading comprehension scores and their hearing mothers' communication strategies and skills. Subjects included 201 students from six randomly selected residential schools for the deaf. Correlation coefficients, stepwise multiple regression analyses and analysis of covariance showed that for this group of subjects, method of communication used by mothers had no significant relationship with their deaf children's reading comprehension scores. No significant relationship was found between reading comprehension of the children of mothers who used manual communication and the age of the child when the mother began to sign. A potential relationship was found, however, between reading comprehension scores and signing skill levels of mothers who used manual communication. 相似文献

A sample of 34 deaf undergraduate college students at Gallaudet University and 46 hearing undergraduate college students at the University of Maryland Baltimore County completed a questionnaire that asked about their knowledge and sources of information concerning the human immunodeficiency virus and acquired immunodeficiency syndrome (HIV/AIDS). The deaf students had significantly lower scores on an "HIV/AIDS Knowledge Index" than the hearing students. This difference could not be explained by the deaf students' gender, class standing, family structure, or father's or mother's education level. The deaf students obtained more of their information about HIV/AIDS from family and friends than the hearing students, who relied to a greater extent on teachers, television, and reading material. The interpersonal sources used by the deaf students are more prone to factual errors than formal sources. Deaf students need methods of educating themselves about HIV/AIDS that are more accurate and that recognize the importance of sources as well as the content of information. 相似文献

Deaf students consistently score lower on standardized measures of reading comprehension than their hearing peers. Most of the studies that have been conducted to explain this phenomenon have focused on variables within the reader, and important differences have been found between deaf and hearing readers. More recently, in the face of increasingly high-stakes consequences, researchers are looking "outside" the reader, at the tests themselves, to determine whether there are fairness issues for special populations, such as deaf students. The study reported here, the first of its kind with deaf students, examines the North Carolina (NC) reading comprehension test. The study employs the same method used originally by NC to determine its appropriateness of the test for the general population of NC students. The experts in this article, like those in the original construction of the NC test, are familiar with the content of the reading curriculum in NC; however, the raters in this article bring a special perspective related to teaching and testing reading of students who are deaf. Findings from this study raise questions about the appropriateness of the NC reading test for deaf students. Implications for future research and instructional practice are discussed. 相似文献

Increasing numbers of students who are deaf or hard of hearing receive educational services in general education classrooms. This placement shift has altered the way teachers of students who are deaf or hard of hearing work, causing an increase in the number of itinerant teachers. As placement trends for students who are deaf or hard of hearing and teachers' job responsibilities have changed, the field of deaf education has only slightly modified professional standards for licensed teachers of students who are deaf or hard of hearing. Most teacher preparation programs continue training preservice teachers to work in self-contained classrooms, leaving itinerant teachers feeling underprepared. Interviews were conducted with 25 experienced itinerant teachers to determine which content and experiences should be included in preparation programs for preservice teachers of students who are deaf or hard of hearing who plan to become itinerant teachers. Results indicate that changes in course work and practical are necessary to best prepare these teachers. 相似文献

The authors examined the effects of captions on deaf students' content comprehension, cognitive load, and motivation in online learning. The participants in the study were 62 deaf adult students who had limited reading comprehension skills and used sign language as a first language. Participants were randomly assigned to either the control group or the experimental group. The independent variable was the presence of captions, and the dependent variables were content comprehension, cognitive load, and motivation. The study applied a posttest-only control group design. The results of the experiment indicated a significant difference (t = -2.16, p < .05) in content comprehension but no statistically significant difference in cognitive load and motivation between the two groups. These results led to suggestions for improvements in learning materials for deaf individuals. 相似文献

In the Netherlands, as in most other European countries, closed captions for the deaf summarize texts rather than render them verbatim. Caption editors argue that in this way television viewers have enough time to both read the text and watch the program. They also claim that the meaning of the original message is properly conveyed. However, many deaf people demand verbatim subtitles so that they have full access to all original information. They claim that vital information is withheld from them as a result of the summarizing process. Linguistic research was conducted in order (a) to identify the type of information that is left out of captioned texts and (b) to determine the effects of nonverbatim captioning on the meaning of the text. The differences between spoken and captioned texts were analyzed on the basis of on a model of coherence relations in discourse. One prominent finding is that summarizing affects coherence relations, making them less explicit and altering the implied meaning. 相似文献

The present study examined whether specific item characteristics, such as mode of acquisition (MoA) of word meanings, make reading comprehension tests particularly difficult for deaf children. Reading comprehension data on nearly 13,000 hearing 7-to-12-year-olds and 253 deaf 7-to-20-year-olds were analyzed, divided across test levels from second to sixth grade (not necessarily corresponding to chronological age). Factor analyses across item scores suggested that, of the determinants studied, MoA--referring to the type of information (perceptual, linguistic, or both) used in word meaning acquisition--was the only factor that contributed significantly to deaf and hearing children's reading comprehension. For hearing children, MoA influenced item scores at the third- and fourth-grade levels. For the deaf children, MoA influenced item scores through the sixth-grade level. 相似文献

This article presents a rich context of information for interpreting Stanford Achievement Test scores and for describing the achievement of deaf and hard-of-hearing students. The publisher's national norming of the Stanford Achievement Test provides a context of actual performance of hearing students. The publisher's Performance Standards provide a context of expectations for hearing students as determined by a panel of experts. The Gallaudet Research Institute's norming of the test on a national sample of deaf and hard-of-hearing students provides a context of test performance by this special population. A smaller subsample of the deaf and hard-of-hearing students who take the same test levels as hearing students provides an additional reference group with respect to the Performance Standards. Information from these sources is brought together into two graphical contexts to address these questions: Can the normative data from the publisher's national standardization of the test with hearing students, and the normative data from the GRI's national norming of the test with deaf and hard-of-hearing students provide a useful context for the interpretation of individual test scores? Can they provide a useful way to examine achievement of groups of students? Can the new Performance Standards defined by the test publisher offer a useful context for test score interpretation for high-achieving deaf and hard-of-hearing students? 相似文献

A national needs assessment survey is described that gathered information on current practices in physical education in both center-based schools for the deaf and mainstream programs serving deaf and hard of hearing students, grades K-12. The manner in which deaf and hard of hearing students are being served in physical education programs, the depth and breadth of curricula, and the credentials needed to teach are described. The study compares similarities and differences among physical education programs in center-based deaf institutions and mainstream schools. In summary, the study identifies areas of concentration needed in curriculum, and methods of teaching appropriate for student teacher candidates. This information has value for physical education programs that are considering revising their curricula to prepare teacher candidates who wish to work with deaf students. 相似文献
