Hearing Status, Language Modality, and Young Children's Communicative and Linguistic Behavior

This study examined early pragmatic skill development in a group of 38 children with severe or profound hearing loss between 1 and 4 years of age who were enrolled in a simultaneous communication (SC) approach to language learning. Both their use of intentionally communicative acts and their use of language were studied in an analysis of 30-min play sessions between a child and the primary caregiver. Results were compared with previously published data from two age-matched groups: 38 deaf children who were enrolled in oral communication (OC) programs and 84 normally hearing (NH) children. All groups showed a significant improvement with age in the communicative behaviors measured; therefore, the overall trend was toward growth-in all age groups-even when the rates of growth differed. By age 3 years, a pattern of communicative function use had emerged in all three groups. Patterns exhibited by deaf children in the SC and OC groups were similar to each other and to younger NH children but dissimilar to NH age mates. Although the use of signed input by normally hearing parents and teachers did not serve to ameliorate the profound effects of hearing loss on communication development in SC children, it did provide some early advantages. The children in SC groups did not exhibit an advantage over children in OC groups in their overall frequency of communication or the breadth of their vocabulary but they began using words earlier and used mature communicative functions significantly more often. Although children in the OC groups did not exhibit a significant advantage in the overall amount of speech used, they showed an advantage in the breadth of their spoken vocabulary in a conversational setting. Implications for early intervention programming are discussed.     

Representational guidance and student engagement: examining designs for collaboration in online synchronous environments

In this paper we report the results of a study which investigated the affordances of multi-user virtual environments (MUVEs) for collaborative learning from a design perspective. Utilizing a mixed methods approach, we conducted a comparative study of the effect of varying representational and interactional design features on a collaborative design activity in three online synchronous environments. We compared environments featuring multiple modes of interaction (MUVEs), shared representations (text chat and 2D still images) and text-only features. Sixty-one students enrolled in an undergraduate course on Child Development participated in the study. Participants were asked to design a theoretically-based, developmentally appropriate, preschool classroom setting. Students were randomly assigned to one of three online learning environments that provided varying levels of representation and interaction. Significant differences in collaborative problem solving interactions were found. Participants in the shared representations + text condition evidenced stronger learning outcomes as regards substantive discussion and integration of child development concepts; while participants in the MUVE condition reported the most enjoyment with the experience. These findings are explained by the concepts of representational guidance, representational bias, educational affordances and interface design metaphors. Suggestions for the design of MUVEs for collaborative learning are provided.

A model using the WISC-R to predict success in programs for gifted students

The present study attempted to develop a quantitative model using the WISC-R that could be used to predict those students most likely to be successful in gifted education programs. The study was conducted in two phases using two groups of gifted children. In phase one, 120 elementary students randomly chosen from a pullout program in a suburban school served as the subject pool. The subjects had varying degrees of success in the program. Phase one subject data were used to develop a quantitative model; phase two subjects were used for predictive purposes. Specific results in phase one yielded six maximally discriminant WISC-R subtests. These subtests were then used to predict at well above chance levels (87.8%) those students who were known to have been either marginally or highly successful in the program (n = 41). The present study goes one step beyond previous research by using these maximally discriminant subtests to predict program performance of gifted children.     

The quest to cultivate an ecocritical awareness in educational technology scholarship: A question of disciplinary focus in the age of environmental crisis

Although many academic disciplines are now experiencing a process of “greening” as scholars seek to cultivate an ecocritical awareness within disciplinary scholarship, Neil Selwyn notes that such ecocritical concerns rarely feature in the field of educational technology. In this paper, I bring Selwyn's call for ecocritical awareness in the field of educational technology into conversation with emerging scholarly discussions in the fields of ecojustice ethics, ecojustice education, and information and communications technology sustainability. In so doing, I expand the existing conversation about the environmental impact of educational technology consumption to argue that the process of cultivating an ecocritical awareness in the field of educational technology requires refining the discipline's focus to include the full lifespan of educational technology devices and the global inequities that feature during the production and disposal of these devices.

Practitioner Notes

What is already known about this topic

• Despite substantive scholarship recognizing the environmental impact of the globalized digital technology supply chain, the field of educational technology has minimally considered the ecojustice implications of the material nature of educational technology devices when examining the environmental impact of these devices.

What this paper adds

• In this paper, I argue that the reason why the field of educational technology has overlooked the environmental impact of device production and disposal is because of its almost exclusive focus on device use. I argue that cultivating an ecocritical awareness in the field of educational technology requires the discipline to expand its focus beyond device use in two ways: (a) to include device production and disposal and (b) to consider the global injustices that occur in these parts of the digital technology life cycle. As such, I build upon Selwyn and others to argue for the cultivation of ecojustice concerns in emerging conversations about ethics in the field of educational technology.

Implications for practice and/or policy

• The process of cultivating ecocritical awareness within the field of educational technology requires expanding the scope and focus of the discipline beyond device use to include device production and disposal. The planned obsolescence behind these devices maximizes the environmental harm at these stages and the global injustices associated with them. Educators and educational leaders seeking to employ educational technology in ethical and environmentally sustainable ways must consider these implications from the global digital technology supply chain.

     

‘Cracks’ in the scholarly communications system: Insights from a longitudinal international study of early career researchers

• 170 early career researchers interviewed three times over 2 years, have uniquely contributed towards a stress test of scholarly communications and cracks have been identified.
• The perfect storm created by the convergence of millennial values and the pandemic appears to have fast-forwarded the cracking process, perhaps, for the good.
• The cracks in question are: (1) peer review; (2) reputational assessment; (3) unethical/questionable practices; (4) collaboration; (5) networking.
