This study examines the mediating effects of parental attributions of children's academic failures in the relationship between maternal failure mind-sets and their parenting styles. Participants were 323 preschool children aged 4-6 years old, with their mothers completing online questionnaires on failure mind-sets, parenting styles, and…

The internal validity of observational study is often subject to debate. In this study, we define the counterfactuals as the unobserved sample and intend to quantify its relationship with the null hypothesis statistical testing (NHST). We propose the probability of a robust inference for internal validity, that is, the PIV, as a robustness index…

Lead poisoning has well-known impacts for the developing brain of young children, with a large literature documenting the negative effects of elevated blood lead levels on academic and behavioral outcomes. In April of 2014, the municipal water source in Flint, Michigan was changed, causing lead from aging pipes to leach into the city's drinking…

This scoping review explores the causal relationship between morphological instruction and reading development in young L2 learners by synthesizing 12 primary studies published between 2004 and 2019 (N = 1,535). These studies focused on reading English as the target language and involved participants between kindergarten and Grade 12 from four…

Student problem behaviors in early elementary school have been associated with increased teacher burnout, negative emotions, and stress, along with negative student outcomes, including increased risk of emotional and behavioral disorders (EBDs). This study examined the impact of BEST in CLASS--Elementary (BEST in CLASS-E), a teacher-delivered Tier…

Background: Observation Studies, Unmeasured Confounding, and Sensitivity Analysis: An important part of educational research is identifying important, potentially causal, factors that influence children's learning from observational studies. However, it is well-known that discovering such factors from observational studies can be biased due to…

Background/Context: Chronic school absenteeism is a pervasive problem across the US; in early education, it is most rampant in kindergarten and its consequences are particularly detrimental, often leading to poorer academic, behavioral and developmental outcomes later in life. Though prior empirical research has identified a broad range of…

This research examined two questions: effects of deception on children's understanding of second-order false belief, and possible effects of number of siblings on second-order performance. Kindergarten children responded to 3 second-order problems that varied in the presence and the nature of deception. Performance was better on the problems…

Children showing poor executive functioning may not fully benefit from learning experiences at home and school and may lag behind in literacy skills. This hypothesis was tested in a sample of 276 kindergarten children. Executive functions and literacy skills were tested at about 61?months and again a year later. In line with earlier studies,…

In the first longitudinal, population-based study of full-day kindergarten (FDK) outcomes beyond primary school in Canada, we used linked administrative data to follow 15 kindergarten cohorts (n ranging from 112 to 736) up to grade 9. Provincial assessments conducted in grades 3, 7, and 8 and course marks and credits earned in grade 9 were…

The study examines the effects of a short period of explicit instruction on the narrative comprehension of French-speaking kindergarteners, as measured by story retell and comprehension questions. A group of kindergarteners that received explicit instruction (n = 15) was compared to a control group that was exposed to the same storybooks and…

This self-study of pretend gunplay in my Transitional Kindergarten (TK) classroom was designed to guide me in not only improving my practice within the classroom, but also informing the development of sound classroom policies related to pretend gun-and-weapons play that balance children's developmental needs with my commitment to peace and…

The present study investigated mathematics performance and related interest value as the antecedents and consequences of teachers' causal attributions concerning children's academic outcomes during their kindergarten year. Sixty-nine children (5-6 years old at the baseline) and their teachers were examined twice during the kindergarten year.…

In recent years, a debate over kindergarten has ensued. We refer to the actors in this debate as "developmentalists," on the one hand, and "academic advocates," on the other. Developmentalists argue that kindergarten should be centered on child-initiated play and intentional teaching through play, art activities, and hands on…

To what extent do children understand that biological processes fall into 1 coherent domain unified by distinct causal principles? In Experiments 1 and 2 (N = 125) kindergartners are given triads of biological and psychological processes and asked to identify which 2 members of the triad belong together. Results show that 5-year-olds correctly…
