Adolescents' perceptions of their fathers' involvement: Significance to school attitudes

Based on data from 2,722 British adolescents aged 14–18 years, this study explored whether perceived father involvement can be associated with school attitudes even after controlling for perceived mother involvement. Multiple regression analysis showed that both father involvement and mother involvement contributed significantly and independently to positive school attitudes. Furthermore, the association between father involvement and school attitudes was the same for sons and daughters. We did not find evidence to support the notion that being in a non‐intact family weakens the association between perceived father involvement and school attitudes. Finally, there was no evidence suggesting that the impact of perceived father involvement on school attitudes depends on the level of perceived mother involvement. © 2002, Wiley Periodicals, Inc.     

Multispecies coalescent and its applications to infer species phylogenies and cross-species gene flow

Multispecies coalescent (MSC) is the extension of the single-population coalescent model to multiple species. It integrates the phylogenetic process of species divergences and the population genetic process of coalescent, and provides a powerful framework for a number of inference problems using genomic sequence data from multiple species, including estimation of species divergence times and population sizes, estimation of species trees accommodating discordant gene trees, inference of cross-species gene flow and species delimitation. In this review, we introduce the major features of the MSC model, discuss full-likelihood and heuristic methods of species tree estimation and summarize recent methodological advances in inference of cross-species gene flow. We discuss the statistical and computational challenges in the field and research directions where breakthroughs may be likely in the next few years.     

Development of children with autism spectrum disorders in special needs education schools in the Netherlands: a three-year follow-up study

The purpose of the study was to investigate the development of symptomatology and academic growth of children with autism spectrum disorders (ASD) attending a special needs education school in the Netherlands as well as to explore the relationship between academic achievement and symptom reduction of those children. To this end a three-year follow up study was conducted by using multiple informants. The group of children with autism was compared with a group of children having other diagnoses but attending the same school. Results showed that teachers’ and parents’ perceptions about children’s symptomatology development differed significantly. Even though teachers reported a significant symptom reduction of ASD symptoms after two years of school attendance the parents of the same children did not. Furthermore, it was found that both groups of children had gains in different aspects of school-based cognitive skills; however, no association was found between symptom reduction and academic growth of the children. Implications of the study are discussed.     

Children’s Teleological Intuitions: What Kind of Explanations Do 7–8 Year Olds Give for the Features of Organisms, Artifacts and Natural Objects?

Research has shown that children usually provide teleological explanations for the features of organisms from a very early age (3?C4?years old). However, it is not clear if teleology is applied selectively for organisms, or if it is generally applied to other objects as well (artifacts and non-living natural objects). The present study examined whether 7?C8?year old students provided teleological explanations for particular organisms, artifacts and natural objects. We investigated whether children's familiarity with these objects influenced the types of explanations they gave. Finally, we also investigated correlations between 'teleology' and 'usefulness' in children's explanations. The results indicate that 7?C8?year olds are able to distinguish between living and non-living entities, as well as that they provide teleological explanations mostly for organisms and artifacts. This may have important implications for biological education, since teleological explanations in classrooms are likely to pose important conceptual obstacles to the development of a scientific understanding of evolution.     

Exploration of teaching strategies that stimulate the growth of academic skills of children with ASD in special education school

The cognitive growth of children with developmental disorders, like autism, can be seriously impaired due to the disorder. If so, in the Netherlands, these children can attend special schools where they are treated to ameliorate disorder symptoms and to stimulate cognitive growth. The aim of this paper was to identify teaching strategies that stimulate the growth of academic skills in children diagnosed with autism, attending a special needs education school in the Netherlands. Findings showed that the strongest underlying teaching strategy that predicted the academic growth of the children on the autism spectrum in the short and long term was the provision of structure in place, time and activities. It was further found that long-term academic gains were partly predicted by the emotional support from their teachers. The implications of the findings are discussed.     

Supporting teachers’ technological pedagogical content knowledge of fractions through co-designing a virtual manipulative

This study explores the impact that co-designing a virtual manipulative, Fractions Lab, had on teachers’ professional development. Tapping into an existing community of practice of mathematics specialist teachers, the study identifies how a cooperative enquiry approach utilising workshops and school-based visits challenged 23 competent primary school teachers’ technological, pedagogical and content knowledge of fraction equivalence, addition and subtraction. Verbal and written data from the workshops alongside observations and interviews from the school visits were analysed using the technological, pedagogical and content knowledge (TPACK) framework. The findings show that the assumptions of even experienced teachers were challenged when Fractions Lab was shared as an artefact on which they were asked to co-design and subsequently interact with, using it in subsequent phases of the cooperative inquiry process. Two original aspects of successful co-design of virtual manipulatives through communities of practice are identified and offered to others: (1) careful bootstrapping of the first design iteration that gathers intelligence about the content area and the technological affordances and constraints available; and (2) involvement of highly motivated teachers who perceive themselves as agents of change in the domain area.     

Secondary School Teachers’ Knowledge and Attitudes Towards Renewable Energy Sources

Investigating knowledge, perceptions as well as attitudes of public that concern various aspects of environmental issues is of high importance for Environmental Education. An integrated understanding of these parameters can properly support the planning of Environmental Education curriculum and relevant educational materials. In this survey we investigated knowledge and attitudes of secondary school teachers in Greece towards renewable energy sources, particularly wind and solar energy systems. A questionnaire with both open and close questions was used as the main methodological instrument. Findings revealed that although teachers were informed about renewable energy sources and well disposed towards these sources, they hardly expressed clear positions regarding several issues about wind and solar energy technologies and farms. Moreover such themes are limited integrated in teaching either as extra curricular educational programs or through the curriculum. These findings cannot confirm that teachers could influence students’ opinion towards renewable energy systems. Thus, authorities should invest more in Environmental Education and relevant Teachers' Education.     

Early Family Environments May Moderate Prediction of Low Educational Attainment in Adulthood: The cases of childhood hyperactivity and authoritarian parenting

Using longitudinal data from the 1970 British Cohort Study, this study explored conditions under which the effects of risk factors for low educational attainment might be moderated. Two different risk factors, hyperactivity and maternal authoritarian parenting attitudes, were studied. The results showed that on the whole these two risk factors were negatively related to educational attainment at age 26. However, mother's authoritarian parenting was not related to educational attainment in children raised in low‐resource (e.g., low social class) environments. Analogously, hyperactivity was less strongly associated with low educational attainment in children raised in low‐stimulation (e.g., maternal depression and low maternal educational attainment) environments. The implications of these findings for intervention programs are discussed.     

Urban neighbourhood quality and school leaving age: Gender differences and some hypotheses

This study used longitudinal data from the 1970 British Cohort Study (BCS70) to examine the role of neighbourhood quality, assessed when cohort members were aged five, in boys’ and girls’ school leaving age. It was expected that, since context is in general more strongly predictive of boys’ rather than girls’ behaviour, neighbourhood quality would be more strongly related to men’s than women’s school leaving age. Results showed that, as expected, even after controlling for cognitive ability, parental socio‐economic disadvantage and social class, family structure, and maternal education, age and depressed mood, neighbourhood quality was more strongly related to men’s than women’s school leaving age. To rule out the possibility that neighbourhood quality is simply picking up individual level social class the study also explored the interaction of neighbourhood quality with parental social class. It was found that, compared to cohort members of high social class groups, cohort members of lower social class groups were less likely to stay in education after the minimum school leaving age in both neighbourhood groups, but being in the lower social class groups was more of a disadvantage for children living in well‐to‐do rather than average or poor neighbourhoods at age five.     

Bullying,moral disengagement and empathy: exploring the links among early adolescents

The present study examined possible interactive links between empathy (cognitive and affective), moral disengagement (MD) and various bullying forms using a mediation model in 301 Greek early adolescents (10–12 years old). Results indicated that both dimensions of empathy were significantly negatively correlated, whereas MD was positively correlated with bullying forms. Two mediation models were tested separately for each gender. Mediation analysis indicated that boys with low affective, but not cognitive, empathy were more likely to demonstrate morally disengaged behaviour which in turn increased self-reported bullying involvement. Moreover, boys with high MD were more likely to report cognitive and affective empathy which resulted in greater direct and indirect relational bullying. In the case of girls, low affective and cognitive empathy evoked highly morally disengaged behaviour which triggered greater involvement in several bullying forms. Finally, cognitive and affective empathy partially mediated the link between MD and all forms of bullying for girls. The findings are discussed in the light of the relevant literature and implications for practice.
