Identifying children with persistent low math achievement: The role of number-magnitude mapping and symbolic numerical processing

Publication date: April 2019Source: Learning and Instruction, Volume 60Author(s): Terry Tin-Yau Wong, Winnie Wai Lan ChanAbstractAlthough an increasing number of research studies have investigated the cognitive deficits related to difficulties in learning mathematics, little is known about whether these cognitive deficits longitudinally predict low mathematics achievement over time. The current 6-year longitudinal study was conducted to address this issue. A sample of 101 students was tested on various numerical and cognitive competencies when they were in kindergarten and in Grade 1. They were then followed until they were in Grade 6, and their mathematics achievement was assessed bi-annually. A group of persistent low mathematics achievers (PLA) who scored consistently below the 25th percentile was identified. This group of PLA showed difficulties in most of the numerical tasks as early as kindergarten. More importantly, three of the early predictors correctly identified 79% of the PLAs. The current findings provide valuable information concerning the core cognitive deficits underlying difficulties in learning mathematics as well as an important tool for educators for identifying children who are at risk of persistent math learning difficulties in the elementary school years.

Authors: Ryba-Stanisławowska M, Sakowska J, Zieliński M, Ławrynowicz U, Trzonkowski P Abstract INTRODUCTION: CD4+ T regulatory cells (Tregs) have been described as the most potent immunosuppressive cells in the human body. They have been found to control autoimmunity, and clinical attempts have been made to apply them to treat autoimmune diseases. Some specific pathways utilized by Tregs in the regulation of immune response or Tregs directly as cellular products are tested in the clinic. Areas covered: Here, we present recent advances in the research on the biology and clinical applications of Tregs in the treat...

METHODS: Retrospective cohort of patients with post-uveitic refractory ME, who received subcutaneous IFN alpha-2a injections for at least 3 months. Baseline central macular thickness (CMT) and best-corrected visual acuity (BCVA) were compared with those at follow-up visits up to 12 months. RESULTS: Thirty-seven patients were include...

Hyperactive platelets are the major culprits in thrombotic disorders. A group of drugs is available to deal with such platelet-related disorders; however, sometimes, side effects and complications caused by these drugs outweigh their benefits. Ginseng and its nutraceuticals have been...

This study sought to analyze the association of early coronary angiography with all-cause mortality and cardiovascular mortality in patients with non–ST-segment elevation acute coronary syndrome (NSTEACS) using a large contemporary cohort of patients with NSTEACS from 2 Spanish tertiary hospitals.MethodsThis retrospective observational study included 5673 consecutive NSTEACS patients from 2 Spanish hospitals between 2005 and 2016. We performed propensity score matching to obtain a well-balanced subset of patients with the same probability of undergoing an early strategy, resulting in 3780 patients. Survival analyses ...
