Not only children but also adolescents and adults encounter great difficulties in learning to reason proportionally. Despite these difficulties, research increasingly shows that proportional reasoning emerges early, before it is being instructed in school. There have however been very few attempts to stimulate this early emerging ability. The aim…

The article explored the impact of topic background knowledge (TBK) on children's language ability development and reading-related emotional factors. TBK refers to the foundational knowledge that children possess concerning a specific subject or topic. The content schemata theory suggests that a high level of TBK facilitates information processing…

The aim of this study was to improve the 2nd- and 3rd-graders' conceptual subitizing skills by using in-class activities, and to examine whether the practice affects the students' basic number processing skills, calculation performance and overall mathematics achievement in the long run. The training was carried out for eight weeks (640 min in…

Children's writing depends on strategic and self-regulated behaviors as well as on attention and transcription skills. Despite the well-established effectiveness of interventions based on the self-regulated strategy development model (SRSD), little is known about their effects when combined with the explicit teaching and systematic training of…

Phonological awareness (PA) and alphabet knowledge (AK) are two of the strongest predictors of reading acquisition, and evidence shows that many New Zealand children are entering school with low levels of emergent literacy (EL) skills. The current research showed that four-year-old children identified as having low levels of EL, who participated…

This study examined the effects of language teaching strategies in Amhara region, Ethiopia on children's phonemic awareness reading performance. To this end, one hundred and two grade one children of two intact sections (n=50) and (n=52) were selected and participated as experimental and control groups, respectively. The research employed…

The goal of this study was to assess whether a short, media literacy intervention could effectively support third- and fourth-graders' abilities to interpret and produce persuasive arguments. The intervention was delivered to students (N = 50) and focused on the knowledge and skills associated with advertising literacy. Students participated in…

A vast majority of elementary students struggle with the core, pre-algebraic concept of mathematical equivalence. The Improving Children's Understanding of Equivalence (ICUE) intervention integrates four research-based strategies to improve outcomes for second grade students: (1) introducing the equal sign before arithmetic, (2) non-traditional…

What constitutes effective teaching of arithmetical skills in early school years is still uncertain. Finger use could play a crucial role in this acquisition, but some children do not use them spontaneously and studies would be necessary to know if it is possible to teach them. This research assesses the impact of a teacher-implemented…

Powell, Berry, et al. (in press) conducted a randomized control trial assessing the effects of two variants of word-problem intervention with third graders (n = 304) experiencing mathematics difficulty. Students were assigned to a business-as-usual condition (BaU) or one of two variants of word-problem intervention. One variant included a…

This study was intended to assess the effect of a psychoeducational computer-assisted and paper-and-pencil training designed to empower visuospatial skills in students attending the second grade of the primary school. At pretest, posttest and at the subsequent 3-months follow-up, 44 Italian second graders were presented with a battery of tests…

The purpose of this study was to investigate the effect of a morphological awareness intervention on the spelling and writing of second-grade (n = 16) and third-grade (n = 10) students at risk for learning disabilities. The intervention was provided for 25 min per session 4 to 5 times per week for 5 weeks. Students were randomly assigned to the…

The purpose of this pilot study was to determine whether positive results from a word-problem intervention implemented one-to-one contributed to similar outcomes when implemented in small groups of three to four students. Third-grade students experiencing mathematics difficulty (n = 76) were randomly assigned to word-problem intervention (n = 56)…

The aim of the study was to examine the improvement of basic science process skills among second graders in science learning through an inquiry-based approach. The participants were 23 students from a second graders class. Participants were with the age around seven years old. The 5E model of inquiry-based approach was used to teach science. Mixed…

The number of opportunities to respond (OTR) and spacing (massed or distributed practice) of practice sessions are important variables to consider in instructional design. The purpose of this pilot study was to compare the impact of these variables on trajectories of mathematics fluency. Second- and third-grade students (N = 112) were randomly…
