This study investigated developmental trajectories of reading and math using latent-growth-curve analyses across multiple academic skills, measures, and multiple time periods within a single sample. Reading-related growth was marked by significant individual differences during the early elementary-school period and nonsignificant individual…

This study investigated whether a latent class of children with math difficulties (MD) or math learning disabilities (MLD) emerged within a heterogeneous sample of learners. A latent class analysis was computed on children (N = 447) in Grade 3 who were administered a battery of math, reading, and cognitive measures. The analysis yielded four…

Decorative pictures, which make a learning text aesthetically appealing rather than provide information, have been predominantly found to impair learning by an increase of learning-irrelevant cognitive processes. Recent research, however, indicates that this effect is moderated by various factors. On the basis of cognitive-affective theories and…

When people attribute human characteristics to nonhuman objects they are amenable to anthropomorphism. For example, human faces or the insertion of personalized labels are found to trigger anthropomorphism. Two studies examine the effects of these features when included in decorative pictures in multimedia learning materials. In a first…

This research examined whether the informational advantage of an animation over a static picture (and over no visualizations as a control condition) can be compensated by presenting the information in the text that constitutes this informational advantage. In addition, it was investigated whether learners' spatial abilities acted as a compensator…

Fluent reading is characterized by rapid and accurate identification of words. It is commonly accepted that such identification relies on the availability of orthographic knowledge. However, whether this orthographic knowledge should be seen as an accumulation of word-specific knowledge in a lexicon acquired through decoding or as a well-developed…

One purpose of this study was to determine whether patterns existed in pre-high school students' motivation-related perceptions of their science classes. Another purpose was to examine the extent to which these patterns were related to their science identification, gender, grade level, class effort, and intentions to persist in science. We…

The authors tested theoretically driven predictions as to the ways in which syntactic awareness, or awareness of word order within sentences, might contribute to reading comprehension, the end goal of reading development and instruction. They conducted a longitudinal study of 100 English-speaking children followed from Grade 3 to 4. Children…

Underperformance in math is a problem with increasing prevalence, complex etiology, and severe repercussions. This study examined the etiological heterogeneity of math performance in a sample of 264 pairs of 12-year-old twins assessed on measures of math achievement, numerosity, and math anxiety. Latent profile analysis indicated 5 groupings of…

Arithmetic word-problem solving is an important component of elementary mathematics curricula that links school mathematics to real-life problem solving. The present 3-year longitudinal study examined children's arithmetic word-problem solving through understanding its 2 component processes: number-sentence construction and computation. Chinese…

There is an ongoing need for literature that identifies the effects of broad contextual risk on school readiness outcomes via family mediating mechanisms. This is especially true amongst diverse and urban samples characterized by variability in immigration history. To address this limitation, family profiles of sociodemographic and contextual risk…

This study evaluated the efficacy of a newly developed Arab-Jewish Class Exchange Program (CEP) in reducing stereotyping and prejudicial attitudes between Israeli-Jewish and Israeli-Palestinian children. The CEP builds on the core principles of contact theory and is designed to help participants cultivate empathy and tolerance toward the other.…

Although children with specific reading disorder (RD) have often been compared to typically achieving children on various phonological processing tasks, to our knowledge no study so far has examined whether the structure of phonological processing applies to both groups of children alike. According to Wagner and Torgesen (1987), phonological…

The goal of this study was to examine how selected pressure points or areas of vulnerability are related to individual differences in reading comprehension and whether the importance of these pressure points varies as a function of the level of children's reading comprehension. A sample of 245 third-grade children were given an assessment battery…

Two studies investigated the importance of initial topic interest (i.e., expectation of interest) and tutors' autonomy-supportive or controlling instructional styles for students' motivation and performance in problem-based learning (PBL). In Study 1 (N = 93, a lab experiment), each student participated in a simulated group discussion in…
