To identify the best possible approaches, we conducted semi-structured interviews with professionals working in the field of early childhood intervention and compared our findings with the international context and previous research. The professionals interviewed for this purpose emphasised the importance of initial team assessments, consistent recommendations to parents, and the implementation of different methods to support the needs of the children and families. Considering these and previous findings, we argue that it is critical to develop a framework of consistent guidelines for all service providers and to find a common language and assessment methods between the different professions and institutions that provide early childhood support. Furthermore, it is important to identify a key person to act as a source of information about the needs of the child and family and to coordinate co-operation between systems.

Direct assessments were conducted for vocabulary and emotional knowledge using the Peabody Picture Vocabulary Test-4 and the Portuguese version of the Emotional Knowledge Assessment Scale, respectively. Additionally, teachers and parents assessed children’s self-control, cooperation, assertiveness, and responsibility using the Portuguese version of the Social Skills Assessment System. Results indicated a significant increase in vocabulary and emotional knowledge over time in the intervention group compared to the control group.

Children can also learn about home through picture books introduced in their classrooms. However, they may experience discrepancies between their lived home experiences and the representations of home in picture books, as they bring diverse notions of home to school. Despite this, there is a paucity of research examining how home is presented and portrayed, particularly in the context of Asian American children’s lives. This study explores the representation of home in Asian/Asian American children's picture books, focusing on how these books address home within the spectrum of multiplicity and mobility. By analyzing 26 books published in the U.S. between 2000 and 2023 featuring Asian/Asian American child protagonists, the data analyses reveal that the concept of home encompasses both materialized and affective aspects, often intertwined in complex ways. The study also highlights that representations of home tend to be monolithic and intertwined with stereotypes of Asians/Asian Americans. This research encourages early childhood education teachers to critically examine the complexities of home, especially beyond those based on Western middle-class values, and offers implications for authors, illustrators, and researchers.</p>","PeriodicalId":47818,"journal":{"name":"Early Childhood Education Journal","volume":"13 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143863040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data was collected through in-depth semi-structured interviews which addressed two overall dimensions of preparedness and practice for diverse contexts. One dealt with perceptions of pedagogical readiness, involving the role of academic/professional training (either at university or vocational levels) in relation to development of PCK, skills and dispositions. The second addressed systemic issues or challenges influencing, or interfering with, educators’ capacity to provide effective practice in diverse settings. Findings revealed that while educators claim to possess a somewhat adequate level of preparedness for diverse contexts, this does not necessarily stem from professional training but rather from experiential knowledge gained through practice.

Without additional support, these children are at risk of poor academic attainment, mental health difficulties and social problems. This study investigated the feasibility of online delivery of the ‘Books Together’ dialogic book sharing programme. School closures due to COVID-19 meant that parents, initially recruited for a randomised controlled trial (RCT) of the “Books Together” programme, were offered an online version. Participants were 44 parents of 3–5-year-old children. An online weekly survey and end of programme questionnaire explored parental responses to the programme. Measures of child language, child behaviour, social-emotional ability, and parenting competence were collected at baseline. The same measures were collected at follow-up, except the child language measure which could not be collected due to COVID-19 restrictions. Online deivery was feasible with 79% of parents completing the programme (mean 6.06 of 7 sessions attended). Parents reported high satisfaction (80 – 97%) with various components of the programme and all reported continuing to book share with their children. The programme achieved significant post-intervention increases in parenting competence and well-being and child prosocial behaviour and social/emotional ability. The programme is low-cost and can increase the parenting strategies that build children’s linguistic abilities. Results suggest that the online programme is as effective as the group based version. The results of this and the previous group based version of the programme justify a larger trial comparing the two delivery modes.</p>","PeriodicalId":47818,"journal":{"name":"Early Childhood Education Journal","volume":"24 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143847071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Measuring the cognitive advancements of young children is more challenging than that of older ones because young children experience vast variations in the different personal, developmental, and environmental factors affecting their learning behaviors. Also, much learning in the early years is informal in nature, posing added challenges in systematic assessment. There are several assessment tools available for evaluating childcare settings and assessing science learning within the context of the classroom, but none for assessing outdoor learning environments. However, research shows that the outdoor physical environment of early childcare facilities has a long-lasting influence on cognitive development as well as on the quality of STEAM learning for children. There is a critical need for systematic tools to assess formal and informal early STEAM learning outdoor environments to advance both fields of early childhood education and design. This systematic review aims to document all existing tools available for assessing (a) the quality of the childcare outdoor environments and (b) the quality of STEAM learning of children aged 3–5 outside the classroom context, addressing the current lack of reliable and valid assessment measures in this emerging field. The synthesis of information from a selection of 20 studies revealed that STEAM-based outdoor learning at the preschool age is a relatively new topic and that there are no assessment tools or indicators that can assess the available opportunities in the outdoor physical environment and their affordances of STEAM learning activities and activity settings in early childhood environments (e.g., childcare centers, family care homes, or preschools). This deficiency demands more research in the areas of systematic environmental assessments of landscape design indicators in early childhood settings to advance spontaneous STEAM learning behaviors in the early years.</p>","PeriodicalId":47818,"journal":{"name":"Early Childhood Education Journal","volume":"93 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143782379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
