Investigating the Validity of the Australian Early Development Index

This article aims to contribute to the ongoing evaluation of the Australian Early Development Index (AEDI) by investigating its construct and concurrent validity with a subsample of 642 children aged 4 to 5 years drawn from the Longitudinal Study of Australian Children (LSAC). Construct validity was examined by considering the theoretical consistency of the network of correlations between the AEDI subconstructs and the independently reported multimethod measures of early learning skills and development collected contemporaneously by the LSAC. Concurrent validity was examined by assessing the extent to which children who were “developmentally vulnerable” on the AEDI domains corresponded with the LSAC outcome indices classification of children as “developmentally at risk.” Moderate to large correlations were observed between each of the AEDI domains and subconstructs when compared to analogous teacher-rated LSAC measures, with lower levels of association observed for parent-rated LSAC measures. Concurrent validity was explored; however, with no criterion measure with which to assess the AEDI, findings are inconclusive prior to predictive validity assessment. Future waves of the LSAC will collect information on the children's abilities at school and developmental outcomes, enabling further interpretation of these concurrent and construct validity findings by triangulation and predictive validity analyses.     

Mushrooms and the Cycle of Life: integrating literature and biology in secondary teacher education

Can two apparently totally different secondary school subjects join forces in an attempt to enrich the learning processes of both? The authors address this question by describing an experimental lesson in which student‐teachers verbalize their preconceptions concerning a natural object (mushrooms) while in the same lesson they do a personal response activity for a poem by Sylvia Plath entitled ‘Mushrooms’. The results indicate that student teachers of different disciplines find this to be a meaningful teaching approach. It proved to be a motivating way to evoke preconceptions about a natural phenomenon by means of a poem and resulted in an enhanced awareness of mushrooms, which culminated in questions on both their growth and reproduction. Moreover, their ‘literary’ interest in the poem and the writer appeared to be stimulated. Possible applications in teaching and teacher training are discussed.     

Childhood Maltreatment and Early Developmental Vulnerabilities at Age 5 Years

This study examined associations between maltreatment and early developmental vulnerabilities in a population sample of 68,459 children (M_age = 5.62 years, SD = .37) drawn from the Australian state of New South Wales, using linked administrative data for the children and their parents (collected 2001–2009). Associations were estimated between (a) any maltreatment, (b) the number of maltreatment types, and (c) the timing of first reported maltreatment and vulnerability and risk status on multiple developmental domains (i.e., physical, social, emotional, cognitive, and communication). Pervasive associations were revealed between maltreatment and all developmental domains; children exposed to two or more maltreatment types, and with first maltreatment reported after 3 years of age, showed greater likelihood of vulnerability on multiple domains, relative to nonmaltreated children.
