We developed a coding rubric based on the Division for Early Childhood (DEC; 2016) Recommended Practices and current literature to examine the quality of information reported about caregiver training across seven domains. In this systematic review, we identified 51 research studies (48 research articles) published between 1982 and 2023 that focused on early childhood mathematics interventions with the involvement of a caregiver. Overall, findings suggest that the identified studies could improve their reporting and/or practices in all domains of caregiver training (i.e., evidence-based training content, family partnerships, delivery, environment, cultural competence, materials, fidelity).

The “sustaining environments” hypothesis posits that for preschool attenders to maintain an advantage over preschool non-attenders, they must experience kindergarten classrooms of sufficiently high quality. Several studies have evaluated this hypothesis by testing whether preschool attenders benefit more than non-attenders from higher quality in their kindergarten classroom. They have produced mostly null findings but have commonly conceptualized the environment as instructional quality in kindergarten classrooms. We expand on this evidence base by testing for moderation of preschool impacts by instructional quality, along with the quality of two other key dimensions of kindergarten classrooms: the self-regulatory environment and the teacher-child relational environment. Moreover, we conduct this test using data on a diverse sample of students from low-income households who attended public preschool in Tulsa, OK, where preschool attendance has been associated with benefits that are sustained through elementary school. Findings suggest that associations between preschool attendance and first-grade outcomes are robust and mostly do not vary by subsequent kindergarten environments. Further tests of this hypothesis should examine variation in kindergarten environments between, rather than within, preschool evaluations. Researchers should also consider other reasons why some public pre-k programs produce more lasting impacts than others.</div></div>","PeriodicalId":48348,"journal":{"name":"Early Childhood Research Quarterly","volume":"72 ","pages":"Pages 56-68"},"PeriodicalIF":3.2,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143418557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the recognized importance of high-quality adult-child interactions for promoting young children's development during this vulnerable phase, supporting such interactions is essential. This study examines the impact of a 9-week domain-specific mathematical interaction training for early childhood education and care (ECEC) teachers on children's development of numeracy skills and mathematical language from age two to four years (N = 408 children). Specifically, it investigates whether the children in groups with teachers trained math-specific, would achieve better outcomes on numeracy skills and mathematical language than a control group who followed their usual program, and, to test for the math-specific effect, to a control-intervention group who received a general interaction training. Moreover, effects on math outcomes were contrasted to general language outcomes to cross-check the training's specific impact. Results showed significant improvements in numeracy skills, in mathematical and general language over time. The math-specific intervention had particularly strong and lasting effects on numeracy and mathematical language, while the general intervention specifically improved general language compared to the control group. The two intervention groups differed significantly in their math and language skills at posttest, but these differences were reduced at follow-up testing. These findings underscore the effectiveness of targeted professional development (PD) training in fostering children's early numeracy skills and mathematical language. By systematically varying intervention content and controlling for environmental factors, this study provides valuable insights into the benefits of math-specific training for ECEC teachers.</div></div>","PeriodicalId":48348,"journal":{"name":"Early Childhood Research Quarterly","volume":"72 ","pages":"Pages 44-55"},"PeriodicalIF":3.2,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143394335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We found that teachers demonstrate a fluid process of understanding that upholds the intricacies of forced displacement and supporting refugees across contexts. All teachers try to hold multiple perspectives and recognize the complexity of the situation, foregrounding a critical evaluation of political discourses about refugees and a sense of scarcity about the current realities and economic constraints. Teachers' understandings are determined by four main factors that interrupt their worldviews and experiences with refugee students: anti-immigrant and political discourses, scarcity, sorrow, and the scrutinizing of the notion of belonging. We note (1) the importance of teachers’ understanding processes as both a core and underrecognized resource in supporting refugee students, and (2) the need to foster dialogic and humanizing stances for teachers to understand and adapt to the dehumanizing realities and constant changes that war and forced displacement bring to their classrooms.</div></div>","PeriodicalId":48348,"journal":{"name":"Early Childhood Research Quarterly","volume":"72 ","pages":"Pages 25-34"},"PeriodicalIF":3.2,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143077664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
