Through a review of the literature on mathematical learning disabilities (MLD) and low achievement in mathematics (LA) we have proposed a model classifying mathematical skills involved in learning mathematics into four domains (Core number, Memory, Reasoning, and Visual-spatial). In this paper we present a new experimental computer-based battery…

To determine whether formative writing assessments that are directly tied to everyday classroom teaching and learning enhance students' writing performance, we conducted a meta-analysis of true and quasi-experiments conducted with students in grades 1 to 8. We found that feedback to students about writing from adults, peers, self, and computers…

School effectiveness research often uses multilevel models in which only direct effects of characteristics of schools on pupil achievement are modelled. Recently, more attention is given to conceptual models that assume indirect and antecedent effects. In this paper, we elaborate on these models and show that the findings from school effectiveness…

Response to intervention (RTI) is a framework for providing interventions and services at increasing levels of intensity until students succeed. The framework helps teachers and schools provide instruction and interventions matched to student needs, monitor progress frequently to guide decisions about changes in instruction or goals, and apply…

In this article I critique six quantitative studies of Reading Recovery and five reviews of Reading Recovery research published in Tier 1 research journals--journals accepted as having high levels of "expert scrutiny" through peer review. I also critique several quantitative research studies of Reading Recovery published in Tier 2…
