In practice—The home of the brave

Whereas some faculty members at the end of their careers choose the tidy comfort of the stand‐alone classroom, Thomas Klein chose the rich and raw life of a residential learning community teacher. Poignant moments from his experience may offer inspiration to other courageous educators.     

The influence of home on learning to read

Large scale investigations into home variables and educational success frequently demonstrate relationships between global factors such as socio-economic status, education of parents, etc. and general educational achievement, of which attainment in reading is often taken as an index. This paper reports a small but detailed study of home influences on the early stages of learning to read within the context of the Bristol Longitudinal Language Development Research Programme. Data were derived from three sources: interviews with the parents when the children were aged 5 and 7 years; regular recordings of spontaneous conversation at home between 3 %and 5 years; assessments of reading at 5 and 7 years. Attainment in reading at age 7 was found to be strongly predicted by knowledge of literacy on entry to school, and this in turn to be predicted by parental interest in literacy and quality of verbal interaction with the child in the preschool years. The child's own pre-school interest in literacy was not found to be strongly associated with later success. The significance of these findings is discussed.     

The effects of reticence on group interaction

Research regarding the effects of reticence on group interaction reveals that reticence does not necessarily impede the group process; however, reticent individuals are seen as less effective participators due to their limited vocal activity, and they are less likely to emerge as the group's leader.

Research on the effects of reticence on group interaction is reviewed and suggestions are made to instructors of the small groups course regarding helping reticent students participate in the small group.     

Influence of structural features on Portuguese toddler child care quality

Whereas child care quality has been extensively studied in the U.S., there is much less information about the quality of child care in other countries. With one of the highest maternal employment rates in Europe, it is important to examine child care in Portugal. Thirty toddler classrooms in child care centers were observed. The purpose of this study was to determine whether structural features account for overall toddler child care quality. Results showed younger and better-paid teachers provided better toddler child care quality. Space available per child was not a statistically significant predictor of toddler child care quality. Overall quality results suggest some issues to be addressed by early education policy makers and indicate the need to promote quality in Portuguese toddler child care programs.     

The influence of children's gender and age on children's use of digital media at home

This study is the first to systematically investigate the influence of child gender and age, on parents’ perceptions of UK children's digital media use at home. It provides an in‐depth exploration of how children's age and gender influence the balance between children's use of digital and non‐digital media at home. The data draw on 709 parents’ responses to an open‐ended question asked in the context of a national survey investigating the digital reading habits of children, conducted in 2015. Parents’ responses were analysed using content and thematic analysis, which yielded eight main categories, collapsed into three major themes: control, child's healthy development and diversity of experiences. Quantitative analyses evidenced that more parents of boys were concerned about the health implications of their children's digital media use and this was a concern especially for parents of the youngest (0–2‐year‐old) children. More parents of 6–8‐year olds cited the appeal of technology as the main reason for the perceived imbalance in their children's engagement with digital media. The study provides a more secure understanding of the factors that influence parental perceptions of their children's digital media use at home, which has implications for policy‐makers, digital designers and early years professionals.     

The quality of toddler child care and cognitive skills at 24 months: Propensity score analysis results from the ECLS-B

Over half of the toddlers in the US experience routine nonparental care, but much less is known about early care than about preschool care. This study analyzed 2-year-old child care and child outcome data from the nationally representative ECLS-B sample of children born in 2001. At two-years of age, 51% of children experienced exclusive parental care, 18% relative care, 15% family child care, and 16% center care. More children in nonparental care were in medium quality care (61%) than in high quality (26%) or low quality (13%) care. Low-income children were more likely than non-low income children to be cared for by their parents and, when in care, were more often in lower quality care. The impact of toddler care quality on cognitive skills was estimated using propensity score adjustments to account for potential selection confounds due to family and child characteristics. Children's cognitive scores were higher in high or medium quality care than in low quality care, but no evidence emerged suggesting that poverty moderated the quality effects. Nevertheless, this suggests that increasing the proportion of low-income children in high quality care could reduce the achievement gap because low-income children are very unlikely to experience high quality care.     

The influence of race/ethnicity on disadvantaged mothers’ child care arrangements

This study uses data from the Fragile Families and Child Wellbeing Study [Reichman, N., Teitler, J., Garfinkel, I., & McLanahan, S. (2001). The fragile families and child wellbeing study: Sample and design. Children and Youth Services Review, 23, 303–326] to describe primary child care arrangements of employed, predominantly low-income mothers of 1-year olds, and to quantify their child care calculus in the post-welfare reform era. The sorting of children across arrangement types differs by mother's race/ethnicity: Hispanic children are most likely to be cared for maternal kin, Black children in organized centers, and White children by their fathers. Multinomial regression reveals that the association between race/ethnicity and arrangement type is largely – but not entirely – accounted for by mothers’ socioeconomic, household, job, and cultural characteristics; interaction tests show that the associations between arrangement type and both poverty status and marital status are contingent on race/ethnicity. These findings indicate that disadvantage does not translate into child care arrangements similarly across racial/ethnic groups and child care policy must take into account structural and cultural differences associated with parents’ race/ethnicity.     

The influence of group size on children's competitive behavior

The present research was designed to test the hypothesis that children would compete more in tetrads than in dyads. Twenty-two pairs of male and 14 pairs of female target children (N = 72) played a competitive game in both tetrads and dyads. Consistent with the hypothesis, male target children competed more in tetrads than in dyads. This hypothesis was not supported for females, however. Analyses of the dynamics of tetrads and dyads further demonstrated that based on a global measure of smiling, the emotional atmosphere was less positive in tetrads than in dyads. The causes and consequences of interaction in different sized social groups are discussed.     

In and out of home care decisions: The influence of confirmation bias in developing decision supportive reasoning

The aims of this study were to identify the themes Social Workers regard as important in supporting decisions to remove children from, or return them to, the care of their parents. To further elicit underlying hypotheses that are discernible in interpretation of evidence. A case study, comprising a two-part vignette with a questionnaire, recorded demographic information, child welfare attitudes and risk assessments, using scales derived from standardised instruments, was completed by 202 Social Workers in Northern Ireland. There were two manipulated variables, mother's attitude to removal and child's attitude to reunification 2 years later. In this paper we use data derived from respondents’ qualitative comments explaining their reasoning for in and out of home care decisions. Some 60.9% of respondent's chose the parental care option at part one, with 94% choosing to have the child remain in foster care at part two. The manipulated variables were found to have no significant statistical effect. However, three underlying hypotheses were found to underpin decisions; (a) child rescue, (b) kinship defence and (c) a hedged position on calculation of risk subject to further assessment. Reasoning strategies utilised by social workers to support their decision making suggest that they tend to selectively interpret information either positively or negatively to support pre-existing underlying hypotheses. This finding is in keeping with the literature on ‘confirmation bias.’ The research further draws attention to the need to incorporate open questions in quantitative studies, to help guard against surface reading of data, which often does not ‘speak for itself.’     

The influence of child,family, home factors and pre‐school education on the identification of special educational needs at age 10

The early identification of young children's special educational needs (SEN), as well as the development of specific strategies to support those children identified with special needs, are increasingly recognised as crucial to facilitating good adjustment to school and to ensuring that such children are helped to reach their full potential in education. Using a large national sample of young children in England whose developmental progress was followed up from pre‐school, this study investigates which child, family, home and pre‐school factors can be viewed as risk or protective factors for later SEN‐status at age 10. The experience of high‐quality pre‐school education is shown to reduce the likelihood of a child being identified as experiencing SEN in the long run. Teachers’ assessments of SEN are found to be strongly related to children's reading and mathematics attainment, but other factors also predict SEN, including a child's age within a year group.

The impact of interactive whiteboards on teacher—pupil interaction in the National Literacy and Numeracy Strategies

The study set out to investigate the impact of interactive whiteboards (IWBs) on teacher—pupil interaction at Key Stage 2 in the teaching of literacy and numeracy. As part of the National Literacy and Numeracy Strategies, IWBs have been made widely available as a pedagogic tool for promoting interactive whole class teaching. In order to investigate their impact, the project looked specifically at the interactive styles used by a national sample of primary teachers. A total of 184 lessons were observed over a two‐year period. Using a computerised observation schedule, teachers were observed in literacy and numeracy lessons, with and without an IWB. The findings suggest that IWBs appear to be having some impact on the discourse moves used in whole class teaching, but this impact is not as extensive as that claimed by the advocates of IWBs. Lessons which used IWBs had a faster pace and less time was spent on group work. The implications of the findings for classroom pedagogy, teachers' professional development and future research priorities are considered.     

The impact of visual communication on the intersubjective development of early parent-child interaction with 18- to 24-month-old deaf toddlers

This article presents a study that examined the impact of visual communication on the quality of the early interaction between deaf and hearing mothers and fathers and their deaf children aged between 18 and 24 months. Three communication mode groups of parent-deaf child dyads that differed by the use of signing and visual-tactile communication strategies were involved: (a) hearing parents communicating with their deaf child in an auditory/oral way, (b) hearing parents using total communication, and (c) deaf parents using sign language. Based on Loots and colleagues' intersubjective developmental theory, parent-deaf child interaction was analyzed according to the occurrence of intersubjectivity during free play with a standard set of toys. The data analyses indicated that the use of sign language in a sequential visual way of communication enabled the deaf parents to involve their 18- to 24-month-old deaf infants in symbolic intersubjectivity, whereas hearing parents who hold on to oral-only communication were excluded from involvement in symbolic intersubjectivity with their deaf infants. Hearing parents using total communication were more similar to deaf parents, but they still differed from deaf parents in exchanging and sharing symbolic and linguistic meaning with their deaf child.     

Effects of transitions to new child care classes on infant/toddler distress and behavior

Changes in distress and problem behaviors of 38 infants/toddlers were examined after children transitioned from familiar to new classrooms to look at effects of non-continuity of caregiver. Child's age, classroom quality, teacher sensitivity, and transitioning with a peer were examined as possible mediators. Results suggest that transitions were associated with increased distress, especially for younger children. In addition, although overall classroom quality was low, children in higher quality pre-transition classrooms showed more distress after transitioning than children in lower quality classrooms. Transitions were associated with decreased problem behaviors. Both distress and problem behaviors returned to pre-transition levels within 3 weeks. Teacher sensitivity and transitioning with a peer did not relate to distress or problem behaviors. These findings contribute evidence about immediate effects of infant/toddler transitions in child care. Future research should explore child, classroom, and teacher–child relationship variables that influence effects of continuity versus non-continuity of caregiver.

The influence of social interaction on meaning construction in a virtual community

As proposed by social constructive theorists, meaningful learning and individual development were achieved through social interaction. To foster social interaction among students, this study formed an online learning community in which they played multiple roles as writers, editors and commentators. In playing different roles, they read peers' texts, edited peers' errors, evaluated peer editors' corrections and finally reconstructed their own texts. Results of this study showed that the multiple roles they played allowed them to have opportunities to view their own texts from others' perspectives. Based on these perspectives, they were more willing to acquire information from and contribute information to peers. All of this extensive information acquisition and contribution resulted in meaning construction of texts as active students improved their final drafts in both local revision (grammatical correction) and global revision (the style, organisation and development of a text) after receiving and evaluating feedback from peer editors. Their final drafts were very different from those of passive students whose first and final drafts were almost the same despite some grammatical revisions. This study suggests that, rather than relying only on an examination of students' final drafts, there may be benefits in teachers encouraging students to actively participate in social interaction by reading peers' texts, editing peers' errors and evaluating peer editors' corrections during text revisions.
