    Increasing Children’s Working Memory Capacity: Preliminary Evaluation of a Card-Based Programme

    Working memory (WM) is recognised as universally foundational to children’s learning. While computerised training programmes can increase working memory capacity, their application in school contexts may be limited by resources and pedagogy, which may restrict use to pupils with the greatest difficulty. This research presents findings from a preliminary evaluation into the effectiveness of a novel, six-week, whole-class working memory programme, which involved pairs of children undertaking daily card-based activities within a single mainstream primary school classroom, involving 24 eight- and nine-year-old children. Post and follow-up measures demonstrated significant gains in children’s working memory and verbal short-term memory, with large effect sizes. While promising, these results should be interpreted with caution due to the sample size and age of participants. Before it can be concluded that this working memory training programme holds potential to increase children’s capacity to learn and achieve, further research needs to establish its usefulness for children with the most prominent WM difficulties, justify its application for children without WM difficulties and eliminate the possibility that gains could have occurred as a result of task-specific learning

    Triplanar Model for the Gap and Penetration Depth in YBCO

    YBaCuO_7 is a trilayer material with a unit cell consisting of a CuO_2 bilayer with a CuO plane of chains in between. Starting with a model of isolated planes coupled through a transverse matrix element, we consider the possibility of intra as well as interplane pairing within a nearly antiferromagnetic Fermi liquid model. Solutions of a set of three coupled BCS equations for the gap exhibit orthorhombic symmetry with s- as well as d-wave contributions. The temperature dependence and a-b in plane anisotropy of the resulting penetration depth is discussed and compared with experiment.Comment: To appear in Physical Review B1 01Mar97; 12 pages with 10 figures; RevTeX+eps
