However, previous studies have measured math language using children’s knowledge or the environmental input of mathematical language, often limiting the scope to specific types of mathematical language. This study examined both numerical (e.g., number-related) and non-numerical (e.g., geometry, measurement, and spatial relations) mathematical expressions used by parents and young children during play and explored how combinations of these math language types related to early math skills. Fifty-eight children aged four to six years and their parents participated in laboratory-based tasks, including a 15-minute play session and a standardized math assessment. The results showed that numerical and non-numerical expressions were used at similar frequencies, and there were strong correlations between parents’ and children’s math language across various types. Mediation analyses revealed that children’s use of math language mediated the relation between the mathematical input they received and their early math skills, but this effect emerged only when advanced numerical and geometry language was considered. These findings emphasize the significance of children’s active use of math language and highlight the need to integrate numerical and non-numerical content in research on early mathematical development.</p>","PeriodicalId":47818,"journal":{"name":"Early Childhood Education Journal","volume":"23 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142449801","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}

Five strategies emerged that facilitate memory retrieval, comparative thinking, and idea synthesis related to idea generation. Additionally, five strategies related to language construction emerged for transitioning children’s language from contextualized to decontextualized forms, enhancing vocabulary, and constructing more complex sentences.

This multiple case study aimed to investigate the extent preschool teachers differentiated content, process, assessment, and learning environment within multicultural classrooms. Four early childhood teachers’ experiences were examined through observations, interviews, photographs, and field notes. It was found teachers used multiple strategies to differentiate their instructional process and content. Strategies of demonstration, providing physical support, peer observation, or repeating directions were prominent for concrete learning. Also, it was determined that teachers implemented several strategies such as using visual materials and activities, and/or diversifying the types of activities for similar topics to differentiate educational content in multicultural classrooms. Moreover, teachers used a limited number of strategies including managing time and resources flexibly as a means of differentiating the learning environment. Similarly, they rarely reported, nor were observed to differentiate assessment. Thus, teachers’ differentiated practices, especially those based on learning environment and assessment, should be developed with effective educational policies.

Yet recommendations for questions tend to focus on form alone, such as encouragement to ask open- rather than closed-ended questions. These recommendations have limited practical application because they frame language as decontextualized and power-free, which can contribute to marginalizing families. Instead, when early educators conceptualize questions as part of discourse—rooted in context and imbued with power—they can better understand nuances of questions and ultimately enact shared decision-making with families. This conceptual paper illustrates the potential of discourse theory as a framework to explore questions and their consequences for decision-making power. Linguistic features of questions are presented along with discursive tools adapted from Gee (2014) that researchers and early educators can use to examine how questions contribute to sharing power or maintaining professional control of decisions. Transcripts from previously conducted, ethically approved investigations using discourse analysis exemplify how the tools can be used to examine how questions function in real conversations between families of infants and toddlers and home visitors. The selected transcripts represent four different home visiting programs in the United States and depict how questions played in role in decision-making about how to support children’s development.</p>","PeriodicalId":47818,"journal":{"name":"Early Childhood Education Journal","volume":"207 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142397844","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}

Eleven preschool teachers participated in a Continuous Professional Development project about play-responsive teaching and science.

Three main themes have been developed: content of the projected image or video, different ways of using projected images or videos, and reasons for using a projected image or video in attempted play-responsive science teaching. Results show that projections could be used as support in play, e.g., when imagining being in another place, like under the surface of the ocean or as a way of introducing science concepts in play.

This article used a quantitative survey to explore the environmental attitudes of 832 early childhood in-service teachers and determined the relationship between their environmental knowledge and attitudes. The Two Major Environmental Values (2-MEV) scale was adopted to examine the environmental attitudes of the participants, including conservation and utilization. The outcomes showed that the participants had a more positive attitude toward environmental conservation and a less positive attitude toward environmental utilization. Although their environmental knowledge was relatively low, it significantly predicted their environmental attitudes toward both conservation and utilization, but the impacts were minimal.

These centers focus on holistic child development through play, care, and learning. Therefore, Norway should be capable of providing young children with the best possible ECEC environment, thereby laying a solid foundation for their future school success. However, Norwegian 15-year-old students score at or below the average in mathematics, reading, and science compared to students in other OECD countries, and average scores are declining OECD (PISA 2022 Results (Volume I): The state of learning and equity in education, 2023). Several factors may contribute to Norwegian students’ average or below-average school performance, e.g., pedagogical weaknesses that were present even before school, in ECEC. An OECD report from 2015 pointed out several challenges in the Norwegian ECEC quality (Early childhood education and care policy review Norway, 2015), related to factors such as structural standards, monitoring of process quality, lack of independence of inspections, lack of understanding regarding monitoring, and insufficient monitoring practices. In this paper, we present: (1) Norwegian policy initiatives implemented in response to the OECD report, and (2) Research conducted after the OECD report on the quality levels of Norwegian ECEC, along with findings from interventions designed to improve quality. Based on this, we discuss the progress since the 2015 OECD report and highlight continuing challenges and important next steps to secure high ECEC quality in Norway for all children. We find that several policy initiatives have been implemented but observed ECEC quality levels after the 2015 report are still in the medium to low range.</p>","PeriodicalId":47818,"journal":{"name":"Early Childhood Education Journal","volume":"12 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142383946","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}
