Longitudinal twin study of early reading development in three countries: Preliminary results

We have initiated parallel longitudinal studies in Australia (Byrne, PI), the United States (Olson, PI), and Norway (Samuelsson, PI) of identical and fraternal twins who are being tested in preschool for prereading skills, and in kindergarten, first grade, and second grade for the development of early reading, spelling, and related cognitive skills. Comparisons of the similarities of identical and fraternal twins will reveal the relative influence of genetic, shared family environment, and nonshared environment on individual differences at and across different stages of development. Family and twin-specific environmental information is also being directly assessed through parent questionnaires and observations by testers. Most of the data collected so far have been from preschool twins (146 in Australia, 284 in the United States, and 70 in Norway). Preliminary analyses for the preschool cognitive measures showed reliable genetic influences on phonological awareness and several measures of memory and learning. In contrast, vocabulary, grammar, and morphology showed significant shared environment and negligible genetic effects. A print knowledge composite showed both genetic and shared environment influence.     

Children and Adults Learn Family-Resemblance Categories Analytically

3 experiments examined the modes of processing used by children and adults in learning family-resemblance categories. The materials were cartoon faces (Experiments 1 and 2) and bugs (Experiment 3) divided into categories that possessed no single defining attributes, but rather several characteristic attributes that were each partially predictive of category membership. The categories were structured so that a holistic mode of processing in which the individual did not selectively weight any given attributes could have led to success. Nevertheless, preschoolers (Experiments 2 and 3), first and third graders (Experiment 1), and adult college students (all experiments) all exhibited primarily analytic modes of learning that consisted of single- and dual-attribute approaches. Although the proportion of analytic learners among the preschoolers was lower than among the adults in Experiment 3, in no case were holistic modes of learning evident. The results are discussed in terms of their implications for young children's apparent relative success in learning natural categories. It is suggested that children's success in learning real-world categories may be based, in part, on an interaction between a basically analytic processing style and natural category structures that provide many partially informative attributes.     

The differential impact of academic self-regulatory methods on academic achievement among university students with and without learning disabilities

Although research on academic self-regulation has proliferated in recent years, no studies have investigated the question of whether the perceived usefulness and the use of standard self-regulated learning strategies and compensation strategies provide a differential prediction of academic achievement for university students with and without learning disabilities (LD). We developed and tested a model explaining interrelationships among self-regulatory variables and grade point average (GPA) using structural equation modeling and multiple group analysis for students with LD (n = 53) and without LD (n = 421). Data were gathered using a new instrument, the Learning Strategies and Study Skills survey. The results of this study indicate that students with LD differed significantly from students without LD in the relationships between their motivation for and use of standard self-regulated learning strategies and compensation strategies, which in turn provided a differential explanation of academic achievement for students with and without LD. These paths of influence and idiosyncrasies of academic self-regulation among students with LD were interpreted in terms of social cognitive theory, metacognitive theory, and research conducted in the LD field.     

Lifting the cover: developing an analytical tool to unravel environmental education resources

Abstract

Evaluations of environmental education (EE) programmes and resources are becoming increasingly visible and important. While benefits accrue through evaluation, many programmes and resources have yet to realise these. Issues such as a lack of clear objectives, reliance on traditional, summative approaches and inattention to context have prevented rigorous evaluation occurring. This paper reports on the development of an analytical tool designed to unravel EE resources. Its theoretical basis is a socially acute questions (SAQ) approach and educational configurations teachers use when implementing this approach. Using these configurations, a series of interrogatory questions were developed to unravel a resource writer’s education intent – what type(s) of knowledge are valued, the view of science presented and the view of learning. Two contrasting resources were analysed to test this tool. This analysis revealed that one resource viewed knowledge as universal, had a scientistic epistemic posture and a doctrinal/pragmatic didactic approach whereas the other viewed knowledge as contextualised, had a relativistic epistemic posture and a problematising/doctrinal didactic approach. Consequently, this tool showed that it was able to unravel a resource writer’s intent, identify gaps so teachers could adapt a resource and build capacity for didactics of EE and its evaluation.     

Head Start in Transition

This article explores the history of Head Start, the federal early education program for economically disadvantaged preschool children in the United States, as a way of understanding what it means to talk about change in the late twentieth century. The history of Head Start has been a story of administrative changes and improvement and accountability initiatives in the realm of public policy, a ominant narrative of progress and rational planning that is consonant with a large, centralized governance structure. In an effort to create another way of conceiving of the organization, we first examine shifting definitions and conflicting interpretations of parental involvement and staff development within the program to reveal some of the tensions inherent in all human endeavors. We then draw on interviews with women who work in and are served by Head Start to show how needs and resources vary and how policy mandates can have differential—and unintended—effects. In the conclusion, we suggest, following Toulmin (1990), that the certainty and stability that has characterized public policy since the Enlightment must now be tempered with a postmodern recognition of change, complexity, and variability. Rather than one history, we see many histories. Instead of one approach, we see value in tailoring improvement initiatives to the needs of families and staff in specific circumstances.     

Etiology of reading difficulties as a function of gender and severity

To test the hypothesis that the etiology of reading difficulties may differ for males and females in more severely impaired samples, reading performance data from monozygotic (MZ), same-sex dizygotic (DZ_ss), and opposite-sex dizygotic (DZ_os) twin pairs were analyzed using a model-fitting implementation of the DeFries-Fulker (DF) model (Purcell & Sham, 2003, Behavior genetics, 33, 271–278). Five non-independent samples were selected using cut-offs of −1 (N = 737 pairs), −1.5 (N = 654), −2 (N = 468), −2.5 (N = 335), and −3 (N = 198) standard deviations (s) below the mean composite reading score of control twins. Male/female gender ratios for children with reading difficulties were significantly higher than 1.0 for all five samples and increased as a function of severity (viz., 1.15, 1.17, 1.40, 1.61, and 1.88, respectively). When the DF model was fit to the data, estimates of heritability (h _g²) and shared environmental influences (c _g²) were not significantly different for males and females in any of the groups. Consequently, the most parsimonious model that provided a good fit to the data at all five levels of severity equated the heritabilities and shared environmental influences for males and females, and fixed the DZ_os coefficient of genetic relatedness at 0.5. Thus, these results provide no evidence for a differential etiology of reading difficulties as a function of gender in more severely impaired samples, and suggest that the same genetic and environmental influences contribute to reading difficulties in males and females, irrespective of severity.     

Feature Article—Continuing Education Module—Reimagining Postpartum Support

This article introduces the author''s emerging new paradigm (“perinatal participation”) that re-imagines postpartum support by helping expectant parents have more peace of mind, confidence, self-compassion, and emotional wellbeing over the course of their perinatal journeys, with special focus on feeling more prepared for all that happens after baby arrives. The author''s work rests on the shoulders of her 1992 book, Mothering the New Mother: Women''s Feelings and Needs After Childbirth. Perceiving a new urgent need to support expectant parents three decades later (the need to alleviate the high stress levels in expectant parents she was talking to) the author explored filtering the expectant and new parent''s experience through what she calls a “peace-of-mind lens.”     

Panic and panacea: brain drain and science and technology human capital policy

Brain drain, the diffusion of skilled human capital, particularly scientific and technical human capital (STHC), from home to host country, is of concern to many nations. Traditional brain drain ‘control’ policies target the human capital embodied in a skilled individual. Based on a case study of brain drain panic in New Zealand in 2000, this paper explores new ‘stimulation’ brain drain policy approaches, including building research excellence and exploiting the diaspora, that take into account the situated and networked nature of STHC. Diaspora policies imply a reframing of ‘national’ STHC no longer circumscribed by geographic boundaries but by national affiliation.     

Differentiated instruction: Hong Kong prospective teachers’ teaching efficacy and beliefs

Catering for learner diversity is one of the key areas in the recent educational reform in Hong Kong. Pre-service teacher education acts as a fundamental way to equip pre-service teachers ready for accommodating diverse learning needs and to build up pre-service teachers’ self-efficacy. The purpose of the study is to examine prospective teachers’ teaching beliefs toward differentiated instruction and teaching efficacy. Using a sequential mixed methods design that contains a questionnaire, focus group interviews, and individual interviews, prospective teachers undertaking a 13-session course regarding differentiated instruction as offered by a local university in Hong Kong participated in the study from January to April 2013. Changes in teaching beliefs regarding differentiated instruction as well as teaching efficacy levels were found. More positive attitudes toward differentiated teaching were found; however, there existed different concerns including class management and conflicts with personal teaching beliefs. These concerns may be related to practical experiences and confidence as well as expectations upon students. Implications for future course development and research are discussed at the end of the paper.
