Sign language recognition and translation: a multidisciplined approach from the field of artificial intelligence

In recent years, research has progressed steadily in regard to the use of computers to recognize and render sign language. This paper reviews significant projects in the field beginning with finger-spelling hands such as "Ralph" (robotics), CyberGloves (virtual reality sensors to capture isolated and continuous signs), camera-based projects such as the CopyCat interactive American Sign Language game (computer vision), and sign recognition software (Hidden Markov Modeling and neural network systems). Avatars such as "Tessa" (Text and Sign Support Assistant; three-dimensional imaging) and spoken language to sign language translation systems such as Poland's project entitled "THETOS" (Text into Sign Language Automatic Translator, which operates in Polish; natural language processing) are addressed. The application of this research to education is also explored. The "ICICLE" (Interactive Computer Identification and Correction of Language Errors) project, for example, uses intelligent computer-aided instruction to build a tutorial system for deaf or hard-of-hearing children that analyzes their English writing and makes tailored lessons and recommendations. Finally, the article considers synthesized sign, which is being added to educational material and has the potential to be developed by students themselves.     

The roles of specialist provision for children with specific speech and language difficulties in England and Wales: a model for inclusion?

Children with specific speech and language difficulties pose a challenge to the education and health systems. In addition to their language difficulties they are also at risk of literacy and social, emotional and behavioural difficulties. The main support for children with more severe difficulties has been enhanced provision in mainstream schools (language units or integrated resources) and special schools. The move to an inclusive education system challenges this tradition. This paper reports the results of interviews with heads of language units/integrated resources and head teachers of special schools (n = 57) as part of a larger study within England and Wales. Their views are considered with reference to criteria for entry to specialist provision, the development of collaborative practice between teachers, teaching assistants and speech and language therapists, and the implications for inclusive education.     

A Grandmothers’ Tea: Evaluation of a Breastfeeding Support Intervention

This study’s purpose was to evaluate an intervention to facilitate grandmothers’ knowledge and support of breastfeeding. A pilot study with a quasi-experimental two-group posttest design was used to evaluate whether the intervention made a difference in grandmothers’ knowledge, attitudes, and intent to recommend breastfeeding. The 26 grandmothers in the intervention group attended A Grandmothers’ Tea program; the 23 grandmothers in the control group received written information. The intervention group had greater posttest knowledge scores than the control group but had no significant differences in attitudes or intent. However, a significant difference was evident between the attitude scores of grandmothers who breastfed their infants and of grandmothers who did not breastfeed their infants regardless of receiving the intervention.     

Peer Victimization: Cause or Consequence of School Maladjustment?

Past research has shown that peer victimization and school maladjustment are related, but it is unclear whether victimization is a cause or consequence of such difficulties. This study examined whether ( a ) peer victimization is a precursor of school maladjustment, ( b ) the effects are limited to the period of victimization, and ( c ) stable peer victimization experiences compound adjustment difficulties. Toward this end, data were collected on 200 5- and 6-year-old children (105 males, 95 females) in the fall and spring of kindergarten. Findings supported the hypothesis that victimization is a precursor of children's loneliness and school avoidance. Whereas children's feelings of loneliness were more pronounced while victimization was occurring, delayed effects were found for school avoidance. Furthermore, the duration of children's victimization experiences was related to the magnitude of their school adjustment problems.     

The impact of tracking by attainment on pupil self-confidence over time: demonstrating the accumulative impact of self-fulfilling prophecy

Abstract

The impact of self-fulfilling prophecy in education, and of attainment grouping on pupil self-perception, remain topics of longstanding debate, with important consequences for social in/justice. Focusing on self-confidence, this article draws on survey responses from 9,059 12-13 year olds who were tracked by subject (‘setting’). They provided survey responses when placed in ‘ability’ sets at the start of their secondary schooling, and again late the following year; enabling analysis of impact over time. After controlling for prior attainment, the gap in general self-confidence between students in the top and bottom sets for mathematics is shown to widen over time, and high set students’ self-confidence in English had also grown significantly; although there was not further widening in the cases of self-confidence in mathematics or in general self-confidence between students in the top and bottom sets for English. Implications of these findings for interventions directed at addressing educational disadvantage are discussed.     

Service-learning in engineering: a valuable pedagogy for meeting learning objectives

Service-learning is an educational practice that has been used successfully in many disciplines, and is defined as ‘a credit-bearing, educational experience in which students participate in an organized service activity that meets identified community needs and reflect on the service activity in such a way as to gain further understanding of course content, a broader appreciation of the discipline, and an enhanced sense of civic responsibility’ (Bringle, R. and Hatcher, J., A service-learning curriculum for faculty. Michigan J. Community Service-Learning, 1995 Bringle, R. and Hatcher, J. 1995. A service-learning curriculum for faculty. Michigan J. Community Service-Learning, 2: 112–122.  [Google Scholar], 2, 112–122). This research examines a first-year biological engineering design course that incorporated a service-learning project. Students participated in a survey and in focus groups to explore how well the service-learning project helped them to meet EC 2000 a–k objectives. Results showed that the service-learning project was a useful teaching method for accomplishing the learning objectives set forth by the instructor and by the Accreditation Board of Engineering and Technology. Women and non-white participants in this study generally assessed their learning outcomes to be greater than white males, which could have important implications in the recruitment and retention of such students in engineering.     

Navigating Community College Transfer in Science,Technical, Engineering,and Mathematics Fields

Given financial barriers facing community college students today, and workforce projections in science, technical, engineering, and math (STEM) fields, the costs of unnecessary delays while navigating transfer pathways are high. In this phenomenological study, we analyzed the delay experiences of 172 students (65% female) navigating community college transfer pathways in STEM fields in Massachusetts. When focusing on institutional delays, three central elements emerged: (a) informational setbacks from dissatisfactory advising, (b) imperfect program alignment with four-year institutions, and (c) college resource limitations. Students took unnecessary courses or could not get into courses in a timely manner, resulting in lost time, money, and credit. An accumulation of delays is particularly detrimental to STEM women and men, given the sequential nature of their programming. Implications for policy and practice are discussed.     

Evaluation Findings from High School Reform Efforts in Baltimore

The Baltimore City Public School System (BCPSS) is one of the first urban districts in the country to undertake large-scale high school reform, phasing in small learning communities by opening new high schools and transforming large, comprehensive high schools into small high schools. With support from the Bill & Melinda Gates Foundation, a dozen local foundations, and school reform developers and technical assistance providers, BCPSS opened 18 small high schools between 2002 and 2006. Using data from surveys, administrative records, and site visits, we examine the implementation and outcomes of these reform efforts. Although BCPSS high schools met many obstacles while implementing the reform, including continual leadership turnover and limited resources, students and staff in the small learning communities reported more positive social and academic environments than their counterparts in the district's comprehensive high schools. In addition, students in small, newly created high schools demonstrated positive academic outcomes (e.g., higher test scores, engagement) relative to students in the other schools in the district.
