The number of low-income families in Singapore is increasing. Young children from impoverished backgrounds are at risk of development gaps and challenges. Research has shown that the accumulation of risk factors from adverse childhood experiences can lead to weaker outcomes later in life. The NTUC First Campus (NFC) launched the Child Support Model (CSM) to serve children and families from vulnerable, low-income backgrounds with a range of financial, social and learning support. A 3-year evaluation study using mixed-methods design was conducted to understand the effects of the CSM and the active ingredients in CSM. A cohort of 58 children from families making a monthly income of SGD$3,500 or less participated in the quantitative component where children's language and cognitive outcomes and classroom engagement were measured at three time points in 2019 (Kindergarten 1) and 2020 (Kindergarten 2). Participating children's parents and teachers were interviewed in the qualitative component and reported their perspectives and experiences in CSM.

The "Pre-K Classroom Assessment Scoring System" (CLASS) is commonly used to measure three domains of teacher-child interactional quality in preschool classrooms (Emotional Support, Classroom Organization, and Instructional Support). However, there is considerable debate regarding the validity of its three-domain factor structure and the applicability of CLASS across different countries and educational settings. This study contributes to this debate with an investigation of the factor structure of the CLASS in Singapore, comparing the factor structure for preschool classrooms serving typically developing children (n = 184) and early intervention classrooms serving children who require early intervention support (n = 182). Bifactor measurement models were used to explore the dimensionality of the CLASS in these settings. A best-fitting bifactor model with one general (Responsive Teaching) and two specific factors (Proactive Management and Routines, Cognitive Facilitation) was a good fit for the overall data. Comparison of preschool and early intervention classrooms indicated partial metric invariance, suggesting that while the factor structure was equivalent across the different settings, the loadings on some dimensions differed between preschool and early intervention classrooms. Future research could examine how different aspects of interactions in different settings contribute to children's learning.

As a result of globalization, kindergarten curriculum frameworks in Asia have been strongly influenced by Western theories, pedagogies, and values. In this article, we argue that Singapore's "Nurturing Early Learners" and Hong Kong's "Kindergarten Education Curriculum Guide" present key notions that are inconsistent with cultural values that are deeply rooted in these two societies. To overcome the challenges these inconsistencies trigger for teachers, principals, teacher educators, and parents, we advocate for the design of 'glocal' (global/local, explicitly hybrid) curriculum frameworks, based on principles that are culturally appropriate and socially situated. Drawing on recent research studies, we analyze current curriculum/practice gaps in relation to the notions of "Child-Centeredness," "Quality Interactions," "Creativity and Self-Expression," and "Play." In seeking the global/local balance that is needed in Singapore and Hong Kong, four alternative glocal notions are proposed: "Child-Appropriateness," "Pedagogical Quality," "Arts Engagement," and "Child-Led Activities." We conclude there is an urgent need for generating a solid corpus of local research in both jurisdictions, which should guide subsequent curriculum reforms and teacher preparation models. Our final aim is to contribute to early childhood education policy discussions in Asia, against the background of internationalization.

Research shows that executive functions (EF) and fine motor skills (FMS) contribute to early academic skills, possibly in overlapping ways. We examine whether and how EF and FMS interact in the concurrent prediction of maths, reading and spelling skills at the start of kindergarten. Structural Equation Modelling (SEM) on data from 1248 five-year-olds supports a compensatory account of EF and FMS in contributing towards maths and spelling skills. Controlling for socio-economic status, age, time spent in kindergarten and intelligence, the influence of EF on spelling achievement was larger for children with poorer compared to better FMS, and vice versa; FMS significantly predicted maths achievement only in children with high but not low EF, and vice versa. Identifying EF or FMS difficulties at or before the start of kindergarten may be important. Different approaches to intervention involving EF and FMS may be appropriate for maths versus spelling skills. We suggest for early childhood curricula to enhance opportunities for FMS development, especially for children who enter kindergarten with poor FMS. [Translation from English by Mercè Rius.]

The current study explored the home and school factors that are important for Singaporean pre-schoolers' (N = 1440) early English development from K1 to P1. Language input quantity and quality factors at home (e.g., number of English books,) and at school (e.g., instructional support in class) were used to predict children's English vocabulary and word reading development using linear mixed-effects models. Children's internal factors (e.g., non-verbal reasoning) were controlled. The results revealed that children who had more English input and higher input quality at home demonstrated faster receptive vocabulary growth. Children's word reading skill was more influenced by the English input quality at home. Children who were frequently read to in English demonstrated faster development in word reading competence. Mother's educational level also mattered: higher maternal education was associated with faster growth in reading skill. The length of time children stayed at school and teachers' qualification also significantly and positively associated with children's English learning. These findings indicate the substantial contribution of the home literacy environment to Singaporean children's early English language development, compared to the quality of teacher-child interactions in preschool. The necessity of more parental involvement in early English language learning at home is discussed under the realm of usage-based theory.

The early childhood sector in Singapore has witnessed vast changes in the past two decades. One of the key policy aims is to improve classroom quality. To ensure a rigorous evaluation of the quality of early childhood environments in Singapore, it is important to determine whether commonly used assessments of quality are valid indicators across different national and community contexts. This study investigated the validity of the Early Childhood Environment Rating Scale-Revised (ECERS-R) in Singapore focused on three major aspects: response process, structural, and criterion validity. Data were collected from 108 classrooms of the main providers of kindergarten programs in Singapore. Initial analyses showed that the quality indicators in most of the ECERS-R items were disordered, which indicated problems with the hypothesized response process underlying the standard ECERS-R scoring system in which high-level indicators are only rated if low-level indicators are met (stop-scoring). To deal with the problem of the "stop-scoring" method, we used the data from a full-scoring method (in which every indicator on every item was rated) in subsequent factor analyses to investigate the internal structure of the ECERS-R. Twenty-two of the 34 items were retained and found to load on two factors, one relating to activities/materials and the other related to language/interactions. Both of the identified subscales and the combined scale showed good internal consistency. The factor score on the combined scale mirrored the ECERS-R full score and could discriminate between classrooms in the top and bottom quartiles of quality scores. Findings on the relationship between the identified factors to the teacher-child ratio and to an alternative measure of classroom quality provided further evidence for criterion validity of the ECERS-R. Implications for the future development and use of the ECERS-R are discussed.

Solving algebraic word problems involves multiple cognitive phases. The authors used a multitask approach to examine the extent to which working memory and executive functioning are associated with generating problem models and producing solutions. They tested 255 11-year-olds on working memory (Counting Recall, Letter Memory, and Keep Track), ability to inhibit inappropriate responses (inhibition: numeric Stroop, Stop Signal), mental flexibility (switching: Number-Letter and Plus-Minus), English literacy, and algebraic problem-solving skills (problem representation, solution generation, and other subcomponents). Working memory explained about a quarter of the variance in both representation and solution formation. Literacy explained an additional 20% of the variance in representation formation. Ability to discern quantitative relationships explained an additional 10%. The findings go beyond a demonstration of an association between working memory and problem-solving accuracy. They show that success in word problems is particularly reliant on ability to decode and assign mathematical operators to quantitative relationships, 2 phases of problem solving that also draw heavily on working memory resources.

The current study examined the mediating role of stress in the linkages between attachment to parents and adjustment to attending higher learning institutions in another country. Self-reports from 114 Malaysian late adolescents studying in Singapore supported the primacy of stress for adjustment; more pertinent, stress mediated all the attachment-adjustment linkages that met the conditions for mediation testing, although this mediating role of stress applied mostly to the late adolescent girls and was also dependent on parent gender.

The behavioral variable employment-related motivational distortion (EMD) was defined and measured. In Study 1, a sample of 250 undergraduates completed the California Psychological Inventory (CPI), Form 434, on two separate occasions in which they responded (a) honestly and (b) as if applying for a job they valued. Four different change measures indexed participants response changes between the two conditions on a CPI-based scale measuring counter productivity (CPI-Cp). A composite of these four measures provided an EMD criterion, which enabled the development, in Study 2, of a 56-item CPI-based EMD predictor scale. On the basis of eight samples comprising a total Nof 2,074, internal consistency and test-retest reliability estimates for the CPI-EMD scale ranged between .72 and .86. Correlations with NEO PI-R domain and facet scales provided construct information about EMD. In Study 3, CPI-Cp scale scores adjusted for EMD manifested (a) reliability ranging from .71 to .87 over eight samples and (b) somewhat different correlations than for the unadjusted scale with Big Five personality scales. In addition, some evidence was found for gains in criterion correlations with EMD adjustments.

Introduction: Sex determination in eutherian mammals is controlled by the Y-linked gene Sry, which drives the formation of testes in male embryos. Despite extensive study, the genetic steps linking Sry action and male sex determination remain largely unknown. Here, we focused on Mmd2, a gene that encodes a member of the progestin and adipoQ receptor (PAQR) family. Mmd2 is expressed during the sex-determining period in XY but not XX gonads, suggesting a specific role in testis development. Methods: We used CRISPR to generate mouse strains deficient in Mmd2 and its 2 closely related PAQR family members, Mmd and Paqr8, which are also expressed during testis development. Following characterization of Mmd2 expression in the developing testis, we studied sex determination in embryos from single knockout as well as Mmd2;Mmd and Mmd2;Paqr8 double knockout lines using quantitative RT-PCR and immunofluorescence. Results: Analysis of knockout mice deficient in Sox9 and Nr5a1 revealed that Mmd2 operates downstream of these known sex-determining genes. However, fetal testis development progressed normally in Mmd2-null embryos. To determine if other genes might have compensated for the loss of Mmd2, we analyzed Paqr8 and Mmd-null embryos and confirmed that in both knockout lines, sex determination occurred normally. Finally, we generated Mmd2;Mmd and Mmd2;Paqr8 double-null embryos and again observed normal testis development. Discussion: These results may reflect functional redundancy among PAQR factors, or their dispensability in gonadal development. Our findings highlight the difficulties involved in identifying genes with a functional role in sex determination and gonadal development through expression screening and loss-of-function analyses of individual candidate genes and may help to explain the paucity of genes in which variations have been found to cause human disorders/differences of sex development.
