Attachment Security Priming Decreases Children's Physiological Response to Threat

Ninety 6- and 7-year-olds (49.3% White, mostly middle class) from greater Washington, DC were randomly assigned to a subliminal priming condition (secure, happy, or neutral) to determine if attachment security priming decreases physiological, expressive, and self-reported fear reactions to threatening stimuli. Dispositional attachment security was also assessed. Secure priming and attachment security each decreased electrodermal reactivity, increased vagal augmentation, and decreased fearful facial expressions compared to control conditions. Examination of a statistical interaction between security priming and child attachment indicated that, although secure children had increased vagal augmentation and fewer fearful expressions than insecure children, the effects of priming were constant across secure and insecure children. There were no priming or attachment effects associated with children's self-reported fear.     

Parent–Infant Room Sharing During the First Months of Life: Longitudinal Links With Behavior During Middle Childhood

Current recommendations encourage parent–infant room sharing for the first 6 months of life. This longitudinal study (N = 193) is the first to examine long-term relations of early room sharing with three domains of child behavior: sleep, behavior problems, and prosocial behavior. Information on room sharing was collected daily for infants’ first 6 months. At ages 6, 7, and 8 years, outcomes were assessed with maternal and teacher questionnaires and behavioral observations. Early room sharing was not related to sleep problems or behavior problems. Additionally, more weeks of room sharing were positively related to higher maternal ratings of child sleep quality and more prosocial behavior. In conclusion, early room sharing appears to be related to positive, but not negative, behavior outcomes in middle childhood.     

Learning Style,Academic Belief Systems,Self-report Student Proficiency and Academic Achievement in Higher Education

Both learning style and academic belief systems have been identified as significant factors contributing to academic achievement. This paper evaluates the efficacy of teaching and learning in higher education by investigating the relationship between students assessment of their own academic proficiency (in this case Research Methods Proficiency [RMP]), learning style, academic locus of control, academic self-efficacy and academic achievement. First and second year undergraduate students' RMP was measured before and after completing modules in Research Methods. Students also completed measures of approaches to learning, academic self-efficacy and academic locus of control. Academic achievement (module mark) was also recorded. Results showed that perceived proficiency increased after completing the taught modules and that perceived proficiency was positively correlated with academic performance. Level 1 students, taught under the recently modified programme, reported significantly higher perceived proficiency than Level 2 students taught under the previous programme. Perceived proficiency was positively correlated with a strategic learning approach and negatively correlated with a surface learning approach and external locus of control beliefs. Academic achievement was also positively correlated with a strategic learning approach and negatively correlated with an apathetic learning approach. A deep learning approach failed to be associated with either RMP or academic achievement. It is suggested that: (i) these findings confirm, to some degree, the suggestion that there is an emphasis in later education on performance rather than learning (Lyddy, 1998); and (ii) perceived proficiency is a useful evaluation measure and is likely to contribute to effective and productive teaching and learning within higher education.     

Topics in dynamic research communities: An exploratory study for the field of information retrieval

Research topics and research communities are not disconnected from each other: communities and topics are interwoven and co-evolving. Yet, scientometric evaluations of topics and communities have been conducted independently and synchronically, with researchers often relying on homogeneous unit of analysis, such as authors, journals, institutions, or topics. Therefore, new methods are warranted that examine the dynamic relationship between topics and communities. This paper examines how research topics are mixed and matched in evolving research communities by using a hybrid approach which integrates both topic identification and community detection techniques. Using a data set on information retrieval (IR) publications, two layers of enriched information are constructed and contrasted: one is the communities detected through the topology of coauthorship network and the other is the topics of the communities detected through the topic model. We find evidence to support the assumption that IR communities and topics are interwoven and co-evolving, and topics can be used to understand the dynamics of community structures. We recommend the use of the hybrid approach to study the dynamic interactions of topics and communities.     

One market,two perspectives,three implications: on the development of the special education market in Sweden

ABSTRACT

This study examines the development of the special education market through changes in demand and supply and discusses its implications on the system of education of students in need of special support informed by two theoretical perspectives. The study found out that the number of students and schools in the special education market has increased. The relative size of the special education market on the demand side has remained stable while an increase is observed on the supply side. The results also show that the private sector has grown relatively better than the public sector on both the demand and supply sides. Almost all the market segments have increased on both the demand and supply sides, especially the resource schools in the special education market segment. Based on these results, three implications are observed and discussed, namely a diverse and an extended special education system, increasing segregation within the special education system and a relative stability in the incidence of student exclusion.     

Preschoolers' Ability to Adopt Justice and Care Orientations to Moral Dilemmas

This study examined the moral reasoning that preschoolers use in resolving moral dilemmas. Children's resolutions and justifications were examined with regard to their care orientation and their justice orientation. Thirty-one preschool children participated in the study (18 girls, 13 boys). Children were each read 4 stone containing moral dilemmas and were asked to resolve these dilemmas. The results indicated that children's answers revealed a care orientation or a justice orientation with equal frequency. At times, children could even accept both orientations to the same dilemma. The data analysis also revealed no gender differences in moral orientation. Results are discussed in terms of children's social-cognitive abilities. Educational implications are also raised.     

Changes Observed in Views of Nature of Science During a Historically Based Unit

Numerous empirical studies have provided evidence of the effectiveness of an explicit and reflective approach to the learning of issues associated with the nature of science (NOS) (c.f. Abd-El-Khalick and Lederman in J Res Sci Teach 37(10):1057–1095, 2000). This essay reports the results of a mixed-methods association study involving 130 preservice teachers during the course of a three class unit based upon the history of science using such an approach. Within the unit the phenomenon of industrial melanism was presented as a puzzle for students to solve. Students were explicitly asked to reflect upon several NOS issues as they developed and tested their own explanations for the “mystery phenomenon”. NOS views of all participants were characterized by means of surveys and follow-up interviews with a subsample of 17 participants, using a modified version of the VNOS protocol (c.f. Lederman et al. in J Res Sci Teach 39(6):497–521, 2002). An analysis of the survey results informed by the interview data suggests NOS views became more sophisticated for some issues, e.g., whether scientific knowledge requires experimentation; but not others, e.g., why scientists experiment. An examination of the interview data informed by our experiences with the unit provides insight into why the unit may have been more effective with regard to some issues than others. This includes evidence that greater sophistication of some NOS issues was fostered by the use of multiple, contextualized examples. The essay concludes with a discussion of limitations, pedagogical implications, and avenues for further research.     

“Slippage” is not a dirty word: considering the usefulness of Giddens' notion of knowledgeability in understanding the possibilities for teacher education

The attempt to understand the relationship between messages intended and messages received has been an enduring issue in teacher education. For the past three decades researchers have made forays into understanding this enduring issue, and in the process have drawn on various explanatory frameworks, one of them being socialisation. In this paper we work with Giddens' structuration theory as well as his concept of knowledgeability as analytical frameworks for understanding the relationship between messages intended (by the teacher educator) and messages received (by the student‐teachers). Our discussion is informed by the findings of a study that investigated student‐teachers' interpretations of the pedagogical process of a physical education teacher education course. Data generated from conversations with, and observations of, the student‐teachers indicated that there was considerable “slippage” between the teacher educator's critical pedagogy inspired intentions and what was understood by the student‐teachers.
