South Africa's basic education system is dysfunctional. It scores last or close to last in a myriad of metrics and delivers learners with some of the worst literacy and numeracy competencies worldwide. A bimodal distribution in the results exists when learners from the richest socioeconomic quintile are performing adequately well, while learners from the poorest quintiles are failing. This paper presents a system dynamics simulation model to describe the causal linkages between improved early childhood and pre-school learning practices on the education system as a whole. The paper investigates the difference in performance between rich and poor communities. Three interventions explore the research question of whether it is the number of enrolments into early childhood development programs that increases a cohort's school readiness, or rather the quality of the early childhood development programs into which they were enrolled. The results answer the research question for the Western Cape province by showing that increasing the quality of the formal ECD programs leads to a greater percentage of school-ready five year olds than increasing the percentage of enrolled children, but that decreasing community poverty leads to better results than either intervention. The results show the simulation model to be a powerful tool to assist with policy setting and intervention testing for any other province or country by simply changing the input data and calibration.

Scholarship remains divided about whether emotional labor is 'skilled'. Interrogating gendered skill constructs that render emotions in work invisible, I examine two organizational contexts in the Early Childhood Education and Care (ECEC) sector: family and center-based care. I draw from 43 interviews, primarily with Latina and White women workers, reflecting feminized and racialized workplaces. I also draw from ethnographic and observational data. Challenging the particular devaluation of family-based care, findings reveal that the practice of skill in emotional labor is organizationally shaped across less and more institutionalized forms of ECEC. Examining worker critiques of professionalization norms and credential-based skill metrics, autonomy is also identified as a pre-requisite for embodied, tacit and discretionary skills in the emotional labor of ECEC.

The massive development of information technology based on big data, internet, and artificial intelligence has brought fundamental changes to human patterns and lifestyles, especially after the COVID-19 pandemic that hit globally, has added to a large and complex problems in parenting, as well as demanding people to take care of their children. Parents must be able to adapt and reposition themselves with new and effective forms of parenting, this can increase parental anxiety. To determine the level of parental anxiety, this research was conducted using a quantitative descriptive method through the distribution of questionnaires based on the GAD-7 instrument. This study focuses on efforts to capture the level of parental anxiety and the need for a new form of parenting. The results can be the basis for further research to find and develop new forms of parenting. The results of research on 669 parents living in West Java, Indonesia, showed that the level of parental anxiety was 63.08% at the level of moderate and severe anxiety. The level of parental satisfaction regarding the form of parenting used is at a low level of 67.12%, while the level of parental interest in the new form of parenting is at a very high level of 98.51%. The need for the latest form of parenting that can respond to the challenges and demands of the times is very necessary to minimize parental anxiety.

As policymakers and school communities work to address underlying causes of achievement gaps and access to quality early childhood education, this study considers the use of 21st Century Community Learning Centers to address early childhood education needs on western U.S. state, Idaho. The study sought to understand the relationship between federal and state policies related to out-of-school opportunities to enhance early childhood education. Utilizing data from a statewide evaluation of Idaho’s 21st Century Learning Centers, the study examined 92 centers providing after school, before school, or summer programs in grades preschool through the third grade to predominately at-risk children. Data collection included quantitative data from a survey given to parents (n = 183), as well as qualitative data collected through site-based interviews, focus groups and observations. Data included a review of historical and current data on participation rates; attendance rates; standardized test scores for program participants in grades PK-3 (n = 3258). Data were analyzed for themes and transfer. The study findings provide further insight into understanding possible relationships between U.S. federal and state policy regarding 21st Century Community Learning Centers on both students’ outcomes and parent satisfaction. The findings further support the role of out-of-school time (OST) experiences in the larger ecosystem of learning and provides insight into understanding how the OST activities are carried over into family life.

The proliferation of electronic content and limited exposure of children to books in Jordan has made both parents and health-care providers more concerned about healthy child development. This research aimed to determine if pediatric primary prevention programs were helpful in reducing screen-time and improving reading habits of children in Jordan, and if there was a correlation between these two factors. Parents attended classes on various topics, one of which dealt with screen-time and reading. Six months later, they were surveyed on these topics. The test group (took the relevant class) and control group (did not take the class) included 30 families each. The mean screen-time was above the recommended guideline of 2 h/day in both groups. Only 37% of the families in the test group, and 17% in the control group followed the guideline. A significant difference in screen-time between the groups was found only during weekends. When asked about the ideal screen-time, parents from the test group reported screen-times that were significantly closer to the recommendations, showing an increase in knowledge, but not a significant change in behavior. Parents, also, believed that children’s exposure to books should be at the much later age of 3–4 years, with actual exposure being < 1 h/day. Moreover, no correlation was found between screen-time and reading time. These findings suggest that short, evidence-based classes helped raise awareness, but were not sufficient for parents to fully adopt the guidelines. Programs that promote behavior modification should be explored to reinforce knowledge gained from educational classes.

This study was conducted to assess the psychosocial and material services provision of Wolisso Kalehiwot Church project/center. Qualitative research design employing phenomenological approach was conducted as to reach on identifying the strengths and challenges practiced in the center. Purposive sampling techniques was used to draw ten respondents from the center (8 from orphans, 2 from staff) to respond to interview questions. The result of this study indicated that the effort made by the project is so effective in addressing the immediate need of the orphans including survival and wellbeing of these children. Consequently, the weakness in the project observed was initial recruitment problem of the orphans and unskilled staffs involving in the project and the inability to be proactive for the sustainability request for the project were seen as major. The challenges faced were identified as characteristics of the staff to handle the growing needs of the orphans, emotional instability of the children, limited access to social integration, negative attitude of the community towards institutionalization and segregation were observed as critical. Hence, institutional capacity building from both external and internal funders to maintain the projects sustainability with clear goal and policy direction is mandatory.
