A study of technical signs in science: implications for lexical database development

Both classroom instruction and lexical database development stand to benefit from applied research on sign language, which takes into consideration American Sign Language rules, pedagogical issues, and teacher characteristics. In this study of technical science signs, teachers' experience with signing and, especially, knowledge of content, were found to be essential for the identification of signs appropriate for instruction. The results of this study also indicate a need for a systematic approach to examine both sign selection and its impact on learning by deaf students. Recommendations are made for the development of lexical databases and areas of research for optimizing the use of sign language in instruction.     

Vygotsky, sign language, and the education of deaf pupils

This article considers the impact of Vygotsky on the education of deaf children in Russia and is a translation/adaptation of an article currently being published in Defektologiia. While Vygotsky perceived sign language as limited in some aspects nevertheless, he always considered that it had a role in education of deaf pupils. He believed that sign language should not be 'treated like an the enemy' and said that 'bilingualism of def people is an objective reality'. However, sign language was banned from Russian schools following a conference decision in 1938. The changing political climate in Russia has lead to the reevaluation of many aspects of life, including approaches to education, and to a reassessment of Vygotsky's ideas and an appreciation of their continuing relevance. Among other things, this has resulted in a reevaluation of the role of sign language for deaf pupils and an emerging interest in sign bilingualism.     

The Role of Students’ Home Language in Science Achievement: A multilevel approach

The present study aimed to identify the role of both student- and school-level characteristics in primary school students’ achievement in the science curriculum. As societies become more culturally and linguistically diverse, many students enter the classroom with a home language that is different from the language of instruction used at school. This study takes into account both the home language and literacy in the language of instruction in relation to student achievement in science subjects. Questionnaires, reading performance tests, and science achievement tests were administered to 1,761 fourth-grade students from 67 schools across Flanders (Belgium). Multilevel hierarchical regression analyses show that the home language and literacy in the language of instruction play an important role in science achievement at the student level, next to gender and socioeconomic status. Students with a home language that is different from the language of instruction experience difficulties with science subjects. Moreover, the higher students’ performance on reading comprehension and self-assessed proficiency in the language of instruction, the higher their score on science achievement tests. At the school level, a school's teachability expectations are one of the key factors related to students’ science achievement. Limitations of this study and future directions for research are discussed.     

Content-area teachers and scaffolded instruction for English language learners

Scaffolding provides content-area teachers (CATs) with an effective means to integrate language instruction into content-area instruction for English language learners (ELLs). Data for this study were derived from 33 CAT discussions while they were pursuing professional development in an American university classroom over 32 weeks. The discussions yielded 408 scaffolding statements that were coded and analyzed. The findings identified linguistic, conceptual, social and cultural scaffolding as part of the CATs’ personal practical knowledge. Also, the findings demonstrated that CATs’ knowledge of cultural scaffolding is limited in comparison to other scaffolding strategies. The findings have an impact on the nature of ELL instruction and its effectiveness.     

The benefits of metacognitive reading strategy awareness instruction for young learners of English as a second language

This paper presents a small‐scale study examining the effects of metacognitive reading strategy instruction on English language learners' reading comprehension in a Hong Kong international school. Twenty‐five primary school (Grade 5) students who learn English as a second language participated in this study. Metacognitive instruction was incorporated into 10 process‐based reading lessons. Data were collected from notes learners took during reading, post‐reading reflection reports, teacher‐facilitated group discussions and two types of reading tests. Results revealed that the young learners could articulate several knowledge factors that influenced their reading. In addition, learners reported a better understanding of the nature and demands of reading, a deeper awareness of metacognitive knowledge in improving reading comprehension and increased confidence in handling reading exercises. The learners also showed enhanced reading performance compared to those in a control group without metacognitive intervention. This study highlights the potential of metacognitive instruction to enhance primary school English learners' reading literacy.     

Inclusion and deaf education: the perceptions and experiences of young deaf people in Northern Ireland and Sweden

The purpose of the present study is to examine what the concept of inclusion means and how it relates to children who are deaf. The paper begins with a background to deaf education, followed by specific reference to how inclusion is perceived in Northern Ireland and in Sweden. It investigates the experiences and opinions of deaf pupils in Schools for the deaf in both countries where different educational philosophies and forms of instruction prevail. A qualitative approach was adopted in which interviews were conducted with deaf pupils who were in their last school year, had left school recently or were in post-compulsory education. The results indicated that Swedish respondents described their experiences markedly more positively than those in Northern Ireland. The main reason for this was the encouragement of a deaf cultural environment where sign language was used by teachers and pupils for instruction and social interaction throughout the school. Although such a culture was not in evidence in Northern Ireland, positive experiences reported by respondents were associated with sign language and a deaf classroom assistant to facilitate comprehension between teachers and pupils. Implications are drawn for effective, inclusive practice in educational settings of deaf children.     

Vowel representations in the invented spellings of Spanish–English bilingual kindergartners

The study compared the invented spelling of vowels in kindergarten native Spanish speaking children with that of English monolinguals. It examined whether, after receiving phonics instruction for short vowels, the spelling of native Spanish-speaking kindergartners would contain phonological errors that were influenced by their first language. Results showed no differences between the two groups on the number of correct short vowel spellings, even though the sounds for four of the five English short vowels do not exist in Spanish. By contrast, differences were observed in the representation of long vowels with a higher rate of error among ELLs. The students had not received explicit instruction in long vowels. ELLs appeared to be trying to represent the diphthongized nature of some English long vowels by spelling long vowels with more than one vowel. The results support the authors’ hypothesis that kindergarten phonics instruction had an impact on the invented spellings of new second language vowel phonemes.     

The use of graphic representations of sign language in leveled texts to support deaf readers

The study considered whether adding sign language graphics to the books being used for reading instruction in a first-grade classroom would promote the literacy development of students who are deaf or hard of hearing. The researchers also sought to discover whether materials existed to put the process of modifying leveled texts within the reach of the typical classroom teacher, in terms of cost and procedure. Students' reading behaviors seemed to indicate that the presence of sign graphics supported their development as readers. The materials needed to create sign support for the English print in the leveled books were commercially available.     

Policy and practice in deaf education: views and experiences of teachers,and of young people who are deaf in Northern Ireland and Sweden

Due to the fact that the outcomes of education for most school leavers who are deaf in Northern Ireland are weak literacy skills and below average reading ages, a study was undertaken to investigate this situation. The views and experiences of teachers of children who are deaf, and of young people who are deaf in Northern Ireland, where oral and total communication forms of instruction are employed in their education were compared with those of Sweden where a sign bilingual is used in education, in the context of current policy and practice. The aim of the study was to find out if there are elements of Swedish policy and practice that could help resolve the situation for Northern Irish learners who are deaf. A qualitative approach was adopted via interviews with teachers of deaf and young people who were deaf in both countries. Findings are reported in relation to policy and practice in education, attitudes to deafness, status of sign language and other factors.     

A mixed-method study of EFL teachers’ Internet use in language instruction

Information and communication technology has affected language instruction in Taiwanese higher education. Varieties of assorted Internet tools are incorporated in educational settings to engage students in learning. To facilitate the improvement of teacher preparation for Internet use, it is important to study the factors influencing teachers in integrating the Internet into their instruction. A concurrent mixed-method approach is employed in this study. Both quantitative and qualitative results show that teacher training is crucial for Internet-integration instruction by the teachers of English as a foreign language (EFL) in Northern Taiwanese higher education institutions. Continuous professional development focused on technology application in language instruction is imperative.     

Evaluating the success of deaf parents

Nineteen parent-child pairs completed the Parental Strengths and Needs Inventory (PSNI) and were interviewed about their relationships. Parent and child scores on the PSNI were above average, with parents expressing high interest in information about childrearing. Interviews revealed issues specific to deaf parents, such as using children as interpreters and frustration when children had poor sign language skills. Children with good sign language skills said they were generally willing to interpret for their parents, except during conflict situations. Children also reported advantages to having deaf parents: they enjoyed being bilingual and their parents tolerated noise and loud music. Study results underscore the importance of triangulation strategies in cross-cultural research.     

Towards achieving the Sustainable Development Goals: Revisiting language of instruction in Tanzanian secondary schools

Research has been conducted on the detrimental effects of using a foreign language for learning in Tanzania’s secondary schools. While most studies recommend the use of a familiar language for instruction, the use of a foreign language in secondary education in Tanzania has been maintained. This has many consequences on the quality of education, and contributes to student dropout. Presenting a study carried out in the semi-rural areas of Dar es Salaam region in Tanzania, this article examines the extent to which language of instruction (LOI) contributes to school dropout. It postulates that the use of a foreign language for teaching and learning in Tanzanian secondary schools hinders the achievement of the United Nations’ Sustainable Development Goals (SDGs). The study’s findings, drawn from exploratory and qualitative narrative research, indicate that, notwithstanding the presence of several other factors, the use of a foreign language as LOI is a major contributor to student dropout. The use of an unfamiliar language of instruction contributes to students’ lack of interest in and disengagement from learning, which ultimately pushes them out of the school system. This is because students usually perform poorly when an unfamiliar language is used as the language of examination and in classroom interaction. The study also reveals that the voices of both teachers and students are not in consonance with what would be expected in an ideal classroom teaching and learning environment. Student dropout from secondary education caused by an inappropriate LOI leads to myriad further problems which, in turn, negatively affect realisation of the SDGs in Tanzania. This article, therefore, concludes that LOI needs to be strongly factored into the development agenda. In order to ensure equitable access to quality secondary education, as required by SDG 4, the Government of Tanzania needs to adopt a language policy that promotes effective teaching and equal access to quality education in secondary schools.     

Does deafness lead to enhancement of visual spatial cognition in children? Negative evidence from deaf nonsigners

This study investigated whether deafness contributes to enhancement of visual spatial cognition independent of knowledge of a sign language. Congenitally deaf school children in India who were born to hearing parents and were not exposed to any sign language, and matched hearing controls, were given a test of digit span and five tests that measured visual spatial skills. The deaf group showed shorter digit span than the hearing group, consistent with previous studies. Deaf and hearing children did not differ in their performance on the visual spatial skills test, suggesting that deafness per se may not be a sufficient factor for enhancement of visual spatial cognition. Early exposure to a sign language and fluent sign skills may be the critical factors that lead to differential development of visual spatial skills in deaf people.     

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.     

Whole language versus code-based skills and interactional patterns in Singapore’s early literacy program

This paper analyzes whole language and code-based skills approaches in early literacy and the specific patterns of interaction present in both approaches. Nineteen hours of video data were coded to analyze the nature of whole language versus code-based skills instruction and document the allocation of time spent on each approach in a reading program. Data come from a cross-sectional study in Singapore where the Learning Support Program (LSP), a reading program for low-track students, was studied in five schools. Overall, 73% of class time in the dataset showed code-based skills instruction. However, the approach to instruction changed within the LSP in a linear fashion. Though in the early years of the LSP there was an over-emphasis on code-based skills and lack of variety in patterns of interaction, in later years there was a balance between whole language and code-based skills and a wider variety of interactional patterns.     

Individual differences in sign language abilities in deaf children

The study attempted to identify characteristics of individual differences in sign language abilities among deaf children. Connections between sign language skills and rapid serial naming, hand motor skills, and early fluency were investigated. The sample consisted of 85 Finnish deaf children. Their first language was sign language. Simple correlations and multiple linear-regression analysis demonstrated the effect of early language development and serial hand movements on sign language abilities. Other significant factors were serial fingertapping and serial naming. Heterogeneity in poor sign language users was noted. Although identifying learning disorders in deaf children is complicated, developmental difficulties can be discovered by appropriate measurements. The study confirmed the results of earlier research demonstrating that the features of deaf and hearing children's learning resemble each other. Disorders in signed and spoken languages may have similar bases despite their different modalities.     

Evaluation of the Effects of the Medium of Instruction on Science Learning of Hong Kong Secondary Students: Students’ Self-Concept in Science

A longitudinal study has been conducted to explore the impact of a new language policy for Hong Kong secondary schools on science learning. According to this policy, only schools that recruit the best 25% of students can teach science in English, the students' second language, while the other schools have to teach science in Chinese, the students' native language. The study involved a student cohort of 100 schools starting from S1 for three years. The outcome of science learning is conceptualized as consisting of students' achievement and self-concept in science. This paper reports the possible effects of English-medium instruction (EMI) and Chinese-medium instruction (CMI) on students' self-concept in science, as measured by students' responses to a questionnaire. Comparing with the CMI students, the EMI students showed higher self-concepts in Chinese, English and Mathematics, but a lower self-concept in science. This finding suggests that the EMI students might experience greater learning problems in science than in other subjects, probably because science learning involves abstract thinking and the mastery of scientific terminology which make a high demand on language proficiency. The EMI students showed a greater interest in learning science than the CMI students, indicating that they were more academically oriented. The EMI students, however, formed a lower perceived self-competence in science than their CMI peers, despite that they performed better in the science achievement test than many of the CMI students. This perception supports the view that using English for instruction may have negative effects on science learning. It is also consistent with the observation that the EMI students perceived science as more difficult to understand and learn than the CMI students.     

Constructing simultaneous communication: the contributions of natural sign language

This article examines simultaneous communication (SC) by analyzing the changes in productions of teachers who underwent a program specifically designed to address improvements in the signed modality by working with both English-based signing and American Sign Language (ASL). Based on theoretical concepts found in bilingualism, language contact situations, and conversational analysis, we focus on the process of constructing utterances by examining the teachers' spontaneous repair sequences as evidence of an active productive system. Two teachers received special instruction in SC that included both ASL and English-based signing systems as separate but equal systems. Videotapes of their use of SC, collected over four years, were analyzed for sign/speech ratio and repair sequences. Repairs were classified as repetitions, replacements, or synchronization. We found that the sign/speech ratio of both teachers increased over time. Examination of repair sequences showed that repetitions tended to occur in speech with the sign channel more completely encoded in the repair. Changes in speech tended to be accompanied by changes in sign. Errors in synchrony were relatively rare. We conclude that the simultaneous communication of both teachers was speech-driven, but error detection was largely sign-driven. The greater the automaticity of both languages, the more attention could be devoted to monitoring the coordination of the two modalities. The amount and quality of monitoring that actually occurred, however, were subject to individual differences.     

Iconicity and sign vocabulary acquisition

This study was designed to investigate learning and retention of isolated sign vocabulary as a function of sign classification (iconic, opaque, or abstract). The subjects were 28 hearing college students naive to sign vocabulary. They were drilled with 30 signs from American Sign Language that had been classified as iconic, opaque, or abstract. Training was conducted using two different media: computer-assisted instruction and videotaped presentation. Performance scores for the three types of signs were significantly different. Scores were consistently higher for iconic signs, regardless of the training mode. The videotaped presentation mode produced the greatest consistency in scores. The results of this study support the notion that it is easier for beginning students of sign language to learn and retain iconic signs.
