Tabula Rasa: case studies of shared governance

This article reviews recently published work which has attempted to understand the key role of subject leaders in secondary schools more clearly. There have been important developments in three areas: theoretical ideas (e.g. the use of contingency theory); policy issues especially with the publication of the TTA (1998) standards for subject leaders and more recently, moves to introduce performance management; and research which has focused on the work of subject leaders and unravelling the characteristics of effective and ineffective departments. Some key issues which need further work include the use of non-contact time, the management of data, monitoring and evaluation and addressing the training needs of subject leaders.

Genetic etiology of spelling deficits in the Colorado and London twin studies of reading disability

The basic multiple regression model for the analysis of selected twin data (DeFries and Fulker 1985, 1988) was fitted to spelling data from 100 pairs of MZ twins and 71 pairs of same-sex DZ twins tested in the Colorado Reading Project (DeFries, Olson, Pennington and Smith 1991), and to data from 12 pairs of MZ twins and 15 pairs of same-sex DZ twins tested in the London twin study of reading disability (Stevenson, Graham, Fredman and McLoughlin 1984, 1987). Estimates of h _g ² obtained from analyses of these data suggest that about 60% of the deficit of probands is due to heritable influences in both samples. When a regression model was fitted separately to data from males and females in the combined Colorado and London samples, resulting estimates of h _g ² were 0.66±0.18 and 0.56±0.19, respectively, a nonsignificant difference. Collaborative analyses of data from additional twin studies of reading disability would facilitate more rigorous tests of hypotheses of differential genetic etiology as a function of group membership.

The importance of shared environment in mother-infant attachment security: a behavioral genetic study

In a sample of 157 monozygotic and dizygotic twins, genetic and environmental influences on infant attachment and temperament were quantified. Only unique environmental or error components could explain the variance in disorganized versus organized attachment as assessed in the Ainsworth Strange Situation Procedure. For secure versus nonsecure attachment, 52% of the variance in attachment security was explained by shared environment, and 48% of the variance was explained by unique environmental factors and measurement error. The role of genetic factors in attachment disorganization and attachment security was negligible. Genetic factors explained 77% of the variance in temperamental reactivity, and unique environmental factors and measurement error explained 23%. Differences in temperamental reactivity were not associated with attachment concordance.

Individual differences in dynamic measures of verbal learning abilities in young twin pairs and their older siblings

We explored the genetic background of individual differences in dynamic measures of verbal learning ability in children, using a Dutch version of the Auditory Verbal Learning Test (AVLT). Nine-year-old twin pairs (N = 112 pairs) were recruited from the Netherlands Twin Register. When possible, an older sibling between 10 and 14 years old participated as well (N = 99). To assess verbal learning, non-linear curves were fitted for each child individually. Two parameters were estimated: Learning Speed (LS) and Forgetting Speed (FS). Larger twin correlations in monozygotic (MZ) than in dizygotic (DZ) and sibling pairs for LS and FS indicated the importance of genetic factors in explaining variation in these traits. The heritability estimate (percentage of variance explained by genetic factors) for LS was 43% for both twins and siblings. For FS heritability was estimated at 20% in twins and was slightly higher (30%) in their older siblings.     

Sex differences in the etiology of aggressive and nonaggressive antisocial behavior: results from two twin studies

Recent theory and results from twin and adoption studies of children and adolescents suggest greater genetic influence on aggressive as compared to nonaggressive antisocial behavior. In addition, quantitative or qualitative differences in the etiology of these behaviors in males and females have been indicated in the literature. The Child Behavior Checklist was completed by the parents of 1022 Swedish twin pairs aged 7-9 years and of 501 British twin pairs aged 8-16 years. Genetic factors influenced aggressive antisocial behavior to a far greater extent than nonaggressive antisocial behavior, which was also significantly influenced by the shared environment. There was a significant sex difference in the etiology of nonaggressive antisocial behavior. Bivariate analyses supported the conclusion that the etiologies of aggressive and nonaggressive antisocial behavior differ for males and females.     

A biometrical analysis of perceptions of family environment: a study of twin and singleton sibling kinships

Biometrical genetic analysis was applied to sibling and twin kinship data on 2 dimensions of perceived home environment. Correlations on 1 dimension, Restrictiveness-Permissiveness, were equal and significant for all kinships: MZ twins, DZ twins, same-sex siblings, and opposite-sex siblings significant for all 4 kinships: MZ twins, DZ twins, same-sex siblings, and opposite-sex siblings (r greater than .40). An E2-E1 biometrical model fitted Restrictiveness-Permissiveness, implying that treatments common to siblings create agreement about perceived environment. As intrapair differences were the same for all 4 kinships under this model, the equal environments assumption of the twin method was supported. In contrast, the Acceptance-Rejection dimension fitted a G-E1 model that makes the assumption that sibling similarity is the result of genetic factors and postulates an absence of shared environmental influences. This finding suggests that this aspect of home environment may depend as much on the child's inherited traits as on actual treatments and is in accord with the genetic analysis of individual traits in that developmentally effective environmental factors do not appear to be common to siblings.     

Negotiating the transition between different teaching contexts through shared responsibility and shared reflection

This paper draws on my personal experiences with coteaching and my participation in the research described by Wassell and LaVan (2009). It examines the role of coteaching in the development of structures that afforded opportunities for shared reflection and shared responsibility between stakeholders in the classroom. It also describes how the schema and practices developed through coteaching and cogenerative dialogue helped mediate the transition between my preservice and inservice teaching experiences.

Effects of role division, interaction, and shared mental model on team performance in project-based learning environment

The purpose of this study was to investigate the cognitive mechanism of project-based learning teams of college students on the basis of the Shared Mental Model (SMM) theory. The study participants were 237 female college students in Korea organized into 51 project teams. To test the study hypotheses, a structural equation modeling was employed. The major study findings are as follows: (1) As hypothesized, member interaction was a strong predictor both for team-related and for task-related SMM. (2) The level of the team’s division of labor reduced the member interactions. (3) Team-related and task-related SMMs were positively associated with team performance. The theoretical and practical implications based on these results are discussed.

柯林伍德和伽达默尔问答逻辑的共通性探析

柯林伍德和伽达默尔作为哲学家,都提出了问答逻辑。柯林伍德是从反对传统历史学研究方法出发,提出了历史哲学视域下的问答逻辑,这本质上是一种方法论上的问答逻辑;而伽达默尔则是从本体论上,在哲学解释学中提出了问答逻辑。对于两者提出的问答逻辑,虽然有不同之处,但更有许多的共通性在其中。两者的理论渊源相同,都是受苏格拉底和培根的影响;内在逻辑结构相同,都是一种问答的结构;都具有开放性的特点。此外,二者在反对科学主义泛滥的倾向方面都起到了积极的作用。
