Adoptive Gay Father Families: A Longitudinal Study of Children’s Adjustment at Early Adolescence

Findings are presented from the second phase of a UK longitudinal study of 33 gay father, 35 lesbian mother, and 43 heterosexual parent families when their adopted children reached early adolescence. Participants predominantly lived in urban/suburban areas and were mostly white and well-educated. Standardized interviews, observations, and questionnaires of parental mental health, parent–child relationships, and adolescent adjustment were administered to parents, children, and teachers between 2016 and 2018. There were few differences between family types. However, adjustment problems had increased in all family types, with better parenting quality and parental mental health associated with fewer adjustment problems. The findings contribute to adoption policy and practice, and to theoretical understanding of the role of parental gender in child development.     

The Vertex Project: Children Creating and Populating 3D Virtual Worlds

This paper outlines early investigations and initial outcomes of The Vertex Project, a school‐based action research project currently underway at Middlesex University. The project aims to explore the potential of Shared 3D Virtual Environments as creative learning tools for children, and looks into the challenges facing their practical integration into the primary classroom. Working in partnership with three primary schools, the project sets out to investigate the teaching and learning possibilities offered by Internet based 3D virtual environments, placing particular emphasis on the opportunities provided by the active participation of children in the design and construction of their own virtual worlds, and in the creation of avatars with which to represent themselves within these spaces.     

Use of rich-media resources by engineering undergraduates

The ability to develop and distribute digital teaching resources in higher education has developed rapidly over the last decade but research into how students use such resources has received limited attention. This study uses questionnaire results, Internet analytic data and semi-structured interviews to examine the use of three types of rich-media teaching resources – lecture podcasts, key-concept videos and tutorial solution videos – by engineering undergraduates. It is found that students value all three types of resource, especially for revision and as a supplement to lectures. Students find short, focused resources more useful than longer ones. Non-native English speakers and those with disabilities derive particular benefits from the resources. The effect of rich-media resources on lecture attendance is found to be small, and two-way.     

Online or Face-to-Face: Do Mission-Related Student Learning Outcomes Differ?

This study investigated how an authentic assessment program was used to examine student learning outcomes within the context of a Christian university’s institutional mission, core values, and distinctive qualities. For the purposes of this study, an authentic assessment program is defined as assessing student-produced work within the context of the institutional mission. A sample of 1,814 undergraduate students taking one or more general education courses at the university during the 2007–2009 academic years was examined for any significant differences in student learning outcomes. A univariate analysis of covariance (ANCOVA) indicated the Student Assessment System (SAS) scores for the online students were not significantly different from the SAS scores for the face-to-face (F2F) students after controlling for course grade. These results suggest that online students achieved the same critical mission-related educational outcomes that the university required of its F2F students. An implication of this finding is that the university just as effectively articulated its faith-based mission and vision to the online students as it did to its students taking classes F2F.     

In‐Place and In‐Time

This article presents parallel and collaborative research and teaching practices that expand approaches to encountering site through the lenses of observation and performative drawing. These drawing practices record phenomena, whilst in their presence, through a designed temporal framework. This asks the drawer to observe over a duration of time and to record the world in motion. By spending an extended period of time in the presence of the phenomenon of our study, with active receptivity, our capacity to see shifts. Rather than the drawn outcomes of this observation recording a past time, the notion of experiential time – and an expanded present – is embedded in the act of drawing. These processes of observation and performative drawing allude to Edmund Husserl’s expression of a ‘thickened present’. The outcomes of this drawing practice demonstrate that observational techniques are embodied, relational, temporal and generative and so offer an alternative approach to site analysis. How this approach sits within the larger domain of spatial temporal relationships and forms of drawing are also considered.     

Coloured overlays and their benefit for reading

Children in mainstream schools compared text on white paper with identical text covered in turn by each of ten differently‐coloured plastic overlays. More than 50% reported improved perception with one or more colours, and were given the best colour to use. About half used the overlays for more than three months and their reading speed increased when the overlays were used. In Study I children were examined twice using different methods and examiners. 47% chose the same colour on both occasions, and showed the greatest improvement in reading fluency, reliable at retest. In Study II children were issued with a random colour, and the greatest improvements in reading speed occurred when the random colour was the same as that previously chosen. Phonological reading strategies were not related to visual symptoms, or the benefit from overlays. Across individuals, reading speed varied by a factor of more than three, for good and poor readers. Study III provided estimates of the prevalence of improvements based on a sample of 426 children from 12 schools: 5% of children read more than 25% faster with a coloured overlay.     

A Dual Inheritance: The Politics of Educational Reform and PhDs in Art and Design

This paper examines the changing relationship of art practice to academic research in higher education since 1960. Whereas art practice was often conceived of as divorced from any notion of academic or theoretical work in the post 1960 art school, by the 1990s the ground had changed to such a degree that it was possible to pursue doctoral study in art practice. This emergence of practice‐based PhDs can be considered as part of a larger shift in art education and its acceptance of theory.     

Rhymes and phonemes in the common unit task: replications and implications for beginning reading

Theorists and practitioners in the field of reading development are currently debating the importance of rhymes and phonemes in beginning reading. In a recent study, Duncan, Seymour and Hill (1997) provided evidence that explicit or meta- awareness of sound is closely linked to reading strategy. Meta-awareness was measured by asking beginning readers to identify the ‘common unit’ shared by two spoken words. Results showed that meta-awareness of phonemes emerged prior to meta-awareness of rhyme, and that reading strategy followed a similar small-to-large progression. This study reports on a replication of the ‘common unit’ task which includes modifications to the original procedure (randomisation of conditions, increased practice, removal of positional references from instructions). The results confirm the pattern observed in the original study. Beginning readers learning by a mixed method can identify shared phonemes but not shared rimes in the common unit task. The implications of this and similar replications are discussed.
