Drawing on research from the fields of developmental and cognitive psychology, Peter Westwood presents a case for high-quality 'first teaching' to prevent students failing in the initial acquisition of numeracy skills. Numeracy and Learning Difficulties provides guidance on how to develop flexible teaching methods and strategies to improve mathematical skills of students. It discusses common areas of learning difficulty in mathematics and looks at ways teachers can determine gaps in students' knowledge, as well as how to develop curricula and problem-solving strategies to address these gaps."--back cover.NumeracyStudy and teaching (Primary)Number concept in childrenLearning disabilitiesAustralianNumeracyStudy and teaching (Primary)Number concept in children.Learning disabilities.372.7/2044Westwood Peter S.854050Australian Council for Educational Research,MiAaPQMiAaPQMiAaPQBOOK9910155103203321Numeracy and learning difficulties2893873UNINA02804nam 2200589z- 450 991055768420332120220111(CKB)5400000000044690(oapen)https://directory.doabooks.org/handle/20.500.12854/76813(oapen)doab76813(EXLCZ)99540000000004469020202201d2021 |y 0engurmn|---annantxtrdacontentcrdamediacrrdacarrierThe Physical Properties of the Groups of GalaxiesBasel, SwitzerlandMDPI - Multidisciplinary Digital Publishing Institute20211 online resource (250 p.)3-0365-1773-1 3-0365-1774-X Galaxy groups consist of a few tens of galaxies bound in a common gravitational potential and contain a significant fraction of the overall universal baryon budget. Therefore, they are key to our understanding of how the bulk of matter in the Universe accretes and forms hierarchical structures and how different sources of feedback affect their gravitational collapse. However, despite their crucial role in cosmic structure formation and evolution, galaxy groups have received less attention compared to massive clusters. This is perhaps in part due to their rarity in being observed and properly characterized. With the advent of eROSITA, many thousands of galaxy groups will be detected by X-ray, complementing optical and SZ coverage. In this Special Issue we collected and organized the latest developments in our understanding of these systems and present future prospects from both observational and theoretical points of view.Research and information: generalbicsscactive galactic nucleiactive nucleiblack holescosmological parameterselliptical galaxiesfossil galaxy groupsgalaxies:abundancesgalaxies:clusters:intracluster mediumgalaxy clustersgalaxy groupsgalaxy surveyshydrodynamical and cosmological simulationshydrodynamical simulationsintragroup medium/plasman/aUV observationsX-ray and optical observationsX-ray observationsX-rays:galaxiesResearch and information: generalLovisari Lorenzoedt1300053Ettori StefanoedtLovisari LorenzoothEttori StefanoothBOOK9910557684203321The Physical Properties of the Groups of Galaxies3025377UNINA
