Across three pre-registered studies (n = 221 4-9-year olds, 51% female; 218 parents, 80% female; working- and middle-class backgrounds; data collected during 2019-2021) conducted in the United States (Studies 1-2; 74% White) and China (Study 3; 100% Asian), we document the emergence of a preference for "strivers." Beginning at age 7,…

Researchers from multiple disciplines have found that fractions and algebra knowledge are linked. One major strand of research has identified children's "units coordination" structures as crucial for success with fractions and algebra via multiplicative reasoning, whereas a second strand of research points to "magnitude…

The current longitudinal study measured 279 kindergartners' (M[subscript age] = 5.76 years; SD = 0.55; 135 females) place value understanding using both approximate and syntactic measures based on previous evidence that early variation in performance on approximate measures was associated with subsequent syntactic place value understanding. In the…

With a focus on content-area reading, this study aimed to (a) understand the sources and prevalence of concurrent and specific difficulties in word-level skills, vocabulary, and knowledge among adolescent struggling readers (ASRs) and (b) explore the relations among reading skills, profiles, and reading comprehension. A dual-measure screening…

It is well known that fraction knowledge is relevant for later success in mathematics. However, many students still face difficulties when dealing with fractions. Predictors of fraction knowledge have been widely examined. Systematizing "mathematical" predictors, whether their predictive contributions are direct or indirectly mediated…

Background: The US government allocated over $2.5 billion in "Elementary and Secondary School Emergency Relief (ESSER)" funds to Washington State for COVID-19 response and ventilation improvements. Despite available funding, gaps persist in supporting schools to successfully use portable air cleaners (PACs). We evaluated PAC needs within…

This study explored emotion situation knowledge of 6-8-year-old primary schoolchildren with language impairment (LI) and its relationship with their peer relations. Emotion situation knowledge contains experience-based predictions and anticipations of what will a person likely feel based on information about a particular social situation. To…

This study was performed to determine preservice elementary mathematics teachers' solution performance of systems of linear equations using geometric representation, algebraic representation and transition from geometric representation to the algebraic representation and the predictive role of preservice elementary mathematics teachers'…

This study investigated the typologies of teacher attitudes toward gifted students and gifted education, along with the predictors of such attitudes. For this purpose, surveys were administered to 339 teachers employed in a large faith-based school system in Australia. Analyses including factor analysis and latent profile analysis were performed…

This study aims to examine the writing performance of primary school fourth-grade students in relation to the student-level variables (writing, reading comprehension, self-regulation-based writing, writing motivation, and writing anxiety) and classroom-level (teacher) variables (knowledge of text-writing instruction and text-writing instruction…

Climate change is not a future problem, it is a significant variation of weather conditions becoming warmer, wetter or drier. It is the longer-term trend that differentiates climate change from natural weather variability. The aim of this research was to determine primary school students' knowledge and attitudes related to climate change among…

Teacher-level factors are theoretically linked to student outcomes in data-based instruction (DBI; Lembke et al., 2018). Professional development and ongoing support can increase teachers' knowledge, skills, and beliefs related to DBI, as well as their instructional fidelity (McMaster et al., 2020). However, less is known about how each of these…

It is widely accepted that general intelligence and phonological awareness contribute to children's acquisition of reading and spelling skills. A further candidate in this regard is orthographic knowledge (i.e., the knowledge about permissible letter patterns). It consists of two components, word-specific (i.e., the knowledge of the spelling of…

Mathematical modeling has been positioned at the forefront of many educational levels globally because modeling reinforces purposeful problem-solving skills, connects mathematics to the real-world, and makes mathematics more meaningful and relevant. This article investigated K-12 practicing teachers' knowledge and attitudes toward mathematical…
