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…

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…

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…

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 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…

Repeated reading (RR) is a common fluency intervention, but recent studies comparing RR to continuous reading (CR; i.e., wide reading) found no significant differences in effects. This prompts the question of whether the mechanism that improves skills is repeatedly reading portions of connected text, or simply reading connected text. The current…

Recent studies highlight the important contribution of phonological working memory (PM) in the early stages of both native and foreign language development. However, research on the effects of PM training on language development is very limited. This study aimed at assessing the effectiveness of a PM training educational intervention as a means of…

Elementary school students struggle in interpreting the equal sign as a symbol denoting equivalence. Although many have advocated using a pan-balance scale to help students develop this understanding, less is known about what features associated with this model support learning. To attempt to control and examine these features, the investigators…

The purpose of this study was to explore the paths by which word-problem intervention, with versus without embedded pre-algebraic reasoning instruction, improves word-problem performance. Students with mathematics difficulty (MD; n = 304) were randomly assigned to a business-as-usual condition or one of two variants of word-problem intervention.…

This study examined what factors might have a positive impact on students' learning outcomes in mathematical understanding and computational thinking skills. Specifically, whether the proposed instructional design combining computational perspectives and an embodied approach in mathematics learning improves (a) mathematics learning, (b)…

The purpose of this study was to determine the effectiveness of an instructional package, Self-Regulated Strategy Development, a cognitive strategy instructional model (POW + TREE), in combination with video self-modeling (VSM) on the improvement on the written expression of three third-grade students with learning disabilities (LD). This…

In the field of second language acquisition (SLA), a large base of research has shown the great influence of L2 reading on L2 vocabulary acquisition. Nevertheless, researchers have also found that acquiring new vocabulary happens rather gradually and in small amounts. Without altering the incidental nature of vocabulary acquisition through…

Spelling is an important skill that is crucial to effective written communication. In this study, brief experimental analysis procedures were used to examine spelling instruction strategies (e.g., whole word correction; word study strategy; positive practice; and cover, copy, and compare) for four students. In addition, an extended analysis was…
