Autonomy describes cognition or behavior that is self-directed, according to personal interests, and free from external influence. This construct is of importance to students who are deaf because it has been shown to be positively related to their post-school transition outcomes, and this population faces unique challenges in this area. To conduct research with this construct, it is necessary to use measures that are valid and reliable for the population of interest. Therefore, a set of exploratory and confirmatory factor analyses validated the unidimensionality of a shortened form of the ARC Self-Determination Scale’s autonomy dimension. A three-factor solution, including a social skills dimension, was measurement-invariant across many groups of students, including those with learning disabilities, emotional disturbances, speech and language impairments, and other health impairments. Although the shortened form of this scale was not unidimensional, as hypothesized, the generalizability of its measurement properties may prove useful. Discussion highlights the differences between these three dimensions and Wehmeyer's theory of self-determination.  相似文献   

Effect of Parent Involvement and Parent Expectations on Postsecondary Outcomes for Individuals Who Are d/Deaf or Hard of Hearing

The purpose of this article is to investigate the potential role of parent involvement and parent expectation in postschool outcomes for individuals who are d/Deaf or hard of hearing (DHH). Students who are DHH have lower retention and employment rates than their peers. Recognizing the importance of family in developmental outcomes for all individuals, this article focuses specifically on the role of parents in facilitating postsecondary outcomes. In an effort to address gaps in the literature in this area, this study utilizes the National Longitudinal Transition Survey 2 (NLTS-2) dataset to measure the effect of parental involvement and expectations as individuals who are DHH transition from secondary grades into a variety of postschool settings. Overall, none of the parental involvement variables were statistically significant when controlling for student and parent demographics. The parental expectation variables that had a statistically significant impact on outcomes included expectations to live independently, to be employed, and to pursue postsecondary education. This article discusses findings in the context of operationalization of study constructs in the NLTS-2 and literature related to transition and parental involvement for students who are DHH.  相似文献   

The effects of American Sign Language as an assessment accommodation for students who are deaf or hard of hearing

Students who are deaf or hard of hearing (SDHH) often need accommodations to participate in large-scale standardized assessments. One way to bridge the gap between the language of the test (English) and a student's linguistic background (often including American Sign Language [ASL]) is to present test items in ASL. The specific aim of this project was to measure the effects of an ASL accommodation on standardized test scores for SDHH in reading and mathematics. A total of 64 fifth- to eighth-grade (ages 10-15) SDHH from schools for the deaf in the United States participated in this study. There were no overall differences in the mean percent of items students scored correctly in the standard vs. ASL-accommodated conditions for reading or mathematics. We then conducted hierarchical linear regression analyses to analyze whether measures of exposure to ASL (home and classroom) and student proficiency in the subject area predicted student performance in ASL-accommodated assessments. The models explained up to half of the variance in the scores, with subject area proficiency (mathematics or reading) as the strongest predictor. ASL exposure was not significant with the exception of ASL classroom instruction as a predictor of mathematics scores.  相似文献   

Effective force and economy of triathletes and cyclists

The effective force applied on the crank, the index of pedalling effectiveness, and the economy of movement at 60, 75, 90, and 105 rev/min cadences were examined in nine cyclists and eight triathletes. Tests were performed on two days. Maximal oxygen uptake was measured and the second ventilatory threshold was estimated on day 1 using a stationary bicycle. On day 2, the four different cadences were tested at about 5% below the second ventilatory threshold. A strain gauge instrumented clip-less pedal mounted on the bicycle enabled us to measure the normal and tangential forces exerted on the pedal, while the pedal and crank angles were monitored with the aid of a video system. Based on this information, the effective force and the index of pedalling effectiveness were calculated. Cyclists produced significantly more effective force and a higher index of pedalling effectiveness at 60 and 75 rev/min and were significantly more economic at all cadences than triathletes. The significant and positive correlation between effective force and economy at all cadences suggests that improvement of the effective force would reflect on economy.  相似文献   

A national perspective on teachers' efficacy beliefs in deaf education     

Garberoglio CL  Gobble ME  Cawthon SW 《Journal of deaf studies and deaf education》2012,17(3):367-383

Teachers' sense of efficacy, or the belief that teachers have of their capacity to make an impact on students' performance, is an unexplored construct in deaf education research. This study included data from 296 respondents to examine the relationship of teacher and school characteristics with teachers' sense of efficacy in 80 different deaf education settings in the US. Deaf education teachers reported high overall efficacy beliefs but significantly lower efficacy beliefs in the area of student engagement than in instructional strategies and classroom management. Teachers' years of experience showed a significant relationship with efficacy beliefs, yet it was the teachers' perceived collective efficacy of their educational setting that ultimately predicted teachers' sense of efficacy. These findings lend credence to the need for further examination of school processes that influence teacher beliefs and attitudes in deaf education settings.  相似文献
