Self-Concept and Deafness: Factors Affecting the Development of Deaf Children

From the perspective of hearing-impaired individuals, deafness or hearing impairment means more than just the inability to hear. Deafness imposes on the individual in almost every aspect of their lives, educationally, socially and emotionally. How then does the hearing-impaired individual perceive himself in relation to others? This paper attempts to answer this question by looking into the literature on the psychosocial factors that might influence the self concept of hearing-impaired individuals.

Three factors are delineated; they are familial acceptance, attitudes of society, and communication. Implications for parents and teachers are suggested.     

Bilingual language development: what do early years practitioners need to know?

This paper considers what early years practitioners need to know about bilingual acquisition. It argues that bilingualism is not only an asset in the classroom and the community, but also an individual and family achievement that requires commitment and determination. The different contexts of bilingual acquisition are considered, along with the implication for a successful outcome. In particular, given our current understanding of the processes of language acquisition, the role of the input in each of the two languages will be discussed; the implications of this for early years teachers/practitioners are also considered in order to find the most effective ways of supporting bilingual development in the classroom.     

Identifying 21st Century STEM Competencies Using Workplace Data

Gaps between science, technology, engineering, and mathematics (STEM) education and required workplace skills have been identified in industry, academia, and government. Educators acknowledge the need to reform STEM education to better prepare students for their future careers. We pursue this growing interest in the skills needed for STEM disciplines and ask whether frameworks for 21st century skills and engineering education cover all of important STEM competencies. In this study, we identify important STEM competencies and evaluate the relevance of current frameworks applied in education using the standardized job-specific database operated and maintained by the US Department of Labor. Our analysis of the importance of 109 skills, types of knowledge and work activities, revealed 18 skills, seven categories of knowledge, and 27 work activities important for STEM workers. We investigate the perspectives of STEM and non-STEM job incumbents, comparing the importance of each skill, knowledge, and work activity for the two groups. We aimed to condense dimensions of the 52 key areas by categorizing them according to the Katz and Kahn (1978) framework and testing for inter-rater reliability. Our findings show frameworks for 21st century skills and engineering education do not encompass all important STEM competencies. Implications for STEM education programs are discussed, including how they can bridge gaps between education and important workplace competencies.     

An Investigation into the Dimensionality of TOEFL Using Conditional Covariance-Based Nonparametric Approach

This article reports two studies to illustrate methodologies for conducting a conditional covariance-based nonparametric dimensionality assessment using data from two forms of the Test of English as a Foreign Language (TOEFL). Study 1 illustrates how to assess overall dimensionality of the TOEFL including all three subtests. Study 2 is aimed at illustrating how to conduct dimensionality analyses for a testlet-based test by focusing on the Reading Comprehension (RC) section in combination with item content analyses and hypothesis testing. The results of Study 1 indicated that both TOEFL forms involve two dominant dimensions corresponding to the Listening Comprehension section and the combination of the Reading Comprehension section and Structure and Written Expression section. The extensive RC analyses from Study 2 revealed strong evidence that a significant amount of the RC multidimensionality came from testlet effects. Confirmatory analyses coupled with exploratory cluster analyses and substantive item content analyses further identified dimensionality structure having to do with reading subskills.     

Academic Self-Concept and Self-Efficacy: How Different Are They Really?

Academic motivation researchers sometimes struggle to decipher the distinctive characteristics of what appear to be highly analogous constructs. In this article, we discuss important similarities between self-concept and self-efficacy as well as some notable differences. Both constructs share many similarities such as centrality of perceived competence in construct definition; use of mastery experience, social comparison, and reflected appraisals as major information sources; and a domain-specific and multidimensional nature. Both predict motivation, emotion, and performance to varying degrees. However, there are also important differences. These differences include integration vs. separation of cognition and affect, heavily normative vs. goal-referenced evaluation of competence, aggregated vs. context-specific judgment, hierarchical vs. loosely hierarchical structure, past vs. future orientation, and relative temporal stability vs. malleability. We argue that self-efficacy acts as an active precursor of self-concept development and suggest that self-concept research separate out its multiple components and subprocesses and invest more effort toward making students less preoccupied with normative ability comparisons in school.     

Preschool children's reasoning about ability

Young children's reasoning about ability was investigated among 155 preschoolers (M = 4 years, 10 months) across 3 studies. Results suggest that preschoolers are sensitive to mental state information when making judgments about another child's ability: They judged a child who finds a task easy to be smarter than one who finds the same task hard. Systematic patterns of errors on recall tasks suggest that preschoolers perceive positive correlations between (a) exerting effort and experiencing academic success, and (b) being nice and having high academic ability. Results from a comparison group of forty 9- to 10-year-olds (M = 9 years, 10 months) suggest that the preschool findings generally reflect emerging patterns of reasoning about ability that persist into later childhood, but that the perceived correlations between high effort and academic outcomes and between social and academic traits diminish with age.     

An Assessment of Environmental Literacy and Analysis of Predictors of Responsible Environmental Behaviour Held by Secondary Teachers in the Hualien Area of Taiwan

This study assessed teachers' environmental literacy and analysed predictors of teachers' responsible environmental behaviour (REB). A nine page instrument was administered by mailed questionnaire to 300 randomly selected secondary teachers in the Hualien area of Taiwan with a 52.3% effective response rate. As a result of stepwise multiple regression analyses, the most parsimonious set of predictors of REB for all teachers included: perceived knowledge of environmental action strategies (KNOW), intention to act, area of residence and perceived skill in using environmental action strategies (SKILL, total r² = 0.3867). For urban teachers, the most parsimonious set of predictors included: intention to act, SKILL, major sources of environmental information and membership in environmental organisations (total r² = 0.4711). For rural teachers, the most parsimonious set of predictors included: KNOW, intention to act and perceived knowledge of environmental problems and issues (total r² = 0.3200). Implications for programme development and instructional practice are presented. Recommendations for further research are also provided.     

Single-cell attachment and culture method using a photochemical reaction in a closed microfluidic system

Recently, interest in single cell analysis has increased because of its potential for improving our understanding of cellular processes. Single cell operation and attachment is indispensable to realize this task. In this paper, we employed a simple and direct method for single-cell attachment and culture in a closed microchannel. The microchannel surface was modified by applying a nonbiofouling polymer, 2-methacryloyloxyethyl phosphorylcholine (MPC) polymer, and a nitrobenzyl photocleavable linker. Using ultraviolet (UV) light irradiation, the MPC polymer was selectively removed by a photochemical reaction that adjusted the cell adherence inside the microchannel. To obtain the desired single endothelial cell patterning in the microchannel, cell-adhesive regions were controlled by use of round photomasks with diameters of 10, 20, 30, or 50 μm. Single-cell adherence patterns were formed after 12 h of incubation, only when 20 and 30 μm photomasks were used, and the proportions of adherent and nonadherent cells among the entire UV-illuminated areas were 21.3%±0.3% and 7.9%±0.3%, respectively. The frequency of single-cell adherence in the case of the 20 μm photomask was 2.7 times greater than that in the case of the 30 μm photomask. We found that the 20 μm photomask was optimal for the formation of single-cell adherence patterns in the microchannel. This technique can be a powerful tool for analyzing environmental factors like cell-surface and cell-extracellular matrix contact.     

Significant life experiences affect environmental action: a confirmation study in eastern Taiwan

Two field studies form the basis of this article. The major purposes of Study 1 were to examine significant life experiences affecting the cultivation of environmental activists in eastern Taiwan, and to reconstruct the life paths followed by those active people who engaged in effective environmental action. 40 usable autobiographical memories were collected and content‐analysed to derive 17 significant life experiences. Based on the 17 accounts, a quantitative questionnaire of 24 items on significant life experiences variables was developed for Study 2. Four hundred and thirty valid questionnaires were analysed. Eighty two respondents with a high level of environmental action were determined to be environmental activists, and 153 with a low level of environmental action were determined to be people apathetic towards environmental protection. It was found that the significant life experiences identified in Study 1 could effectively distinguish environmentally committed people from those apathetic to environmental protection. Study 2 also found that 54.6% of the variances in environmental actions could be explained by the significant life experiences.
