A study on middle school students' use of computer-generated representations as they solve probability tasks
No full textThis study examined the problem-solving behavior of four students from an urban, middle school as they used computer simulation software to solve probability tasks, by generating and interpreting computer data and representations to make decisions about fairness and adequacy of sample size. The questions that guided the study were: (1) How are data generated by the students from computer simulations interpreted with respect to (a) fairness and (b) significance of sample size? (2) What decisions about fairness and adequacy of sample size do students make on the basis of evidence that they collect? and (3) How are student ideas influenced, if at all, by their computer-generated representations and others? The students were video-taped during five sessions which occurred on two days of a summer institute, a component of the Informal Mathematical Learning (IML) Project at Rutgers University. Data consisted of discussions between and among students as they worked in pairs on the task, conversations between students and researchers, screen-shots of computer representations that students selected and discussed, and students’ written work recorded on CDs. These were analyzed using the Powell, Francisco & Maher (2003) model for investigating the development of mathematical knowledge using video data. Analysis of the data revealed that the simulation software, together with social interaction, resulted in students' making and testing conjectures about a sophisticated concept, the Law of Large Numbers. The type of representations that were chosen by students also influenced their arguments. The students agreed that fair dice have a uniform frequency distribution; however, they also agreed that a fair die could have an outcome that alternated between having the highest and then lowest frequencies in two separate experiments. This study contributes to the data base that documents the building of mathematical ideas as students work on investigations in supportive environments, and addresses a gap in the probability education literature for studies of middle-school students using simulation software to generate data and representations that support their claims.Ed.D.Includes bibliographical referencesby Barbara Tozz

'A date with Barbara': paracosms of the self in biographies of Barbara Newhall Follett
No full textIn 1927, 13-year-old Barbara Newhall Follett published her first book, the critically acclaimed novel, The House Without Windows and Eepersip's Life There.
Twelve years later, on December 7, 1939, 25-year-old Barbara quarrelled with her husband and left her apartment in Boston with $30 in her pocket, and a notebook. She was never seen again.
The House Without Windows is set in a paracosm (Farksolia) she invented, and ends with the metamorphosis of the titular character into a 'fairy-a wood nymph … invisible for ever to all mortals, save those few who have minds to believe, eyes to see'.
In Barbara's (auto)biography, The Unconscious Autobiography of a Child Genius (1966), written by Harold Grier McCurdy 'in collaboration with Helen Follett' (Barbara's mother), the authors wonder: 'Can we be far wrong in substituting Barbara's name for Eepersip's in the closing scenes of [House Without Windows]?
In this paper, I grapple with the formal and ethical challenges of writing about Barbara Newhall Follett, and the ways her family and others have approached the problem of writing her unresolved life story: a child raised and educated in solitude, a celebrated 'natural' child author, a young woman whose disappearance remains unsolved. The paper will explore the ways in which adults write the stories of children's lives, as nostalgia and fable, as fairytale and paracosmic narrative, and the ways in which Barbara's biographers have, consciously and unconsciously, created biographical concordances, or paracosms of the self, in seeking to make meaning of her life's story

Barbara Dicker Oration 2018 - The phenomenon of hallucinations
No full textThe 2018 Barbara Dicker Oration was presented by Professor Iris Sommer on 13 September 2018. Professor Sommer is a best-selling author and Professor of Cognitive Aspects of Neurological and Psychiatric Disorder at the Department of Neuroscience at the University Medical Center Groningen, Netherlands. Entitled The phenomenon of hallucinations, Professor Sommer offered a holistic view into the research and experiences of hallucinations. It’s actually more common than you might think but what happens in our brains when we hallucinate? And what does this mean for new treatments and interventions

Resti faunistici dai livelli neolitici della grotta Verde di Capo Caccia (Alghero, SS)
No full textLa grotta Verde, situata a Capo Caccia presso Alghero nella Sardegna settentrionale è stata oggetto di alcune campagne di scavo a partire dagli anni 50 del XX secolo. Si tratta di una cavità costiera complessa comprendente un vano emerso situato presso l’ingresso e alcuni vani attualmente sommersi. La grotta risulta frequentata a partire dal Neolitico antico fino al Neolitico recente/Eneolitico. I resti faunistici mostrano una prevalenza di fauna domestica formata da ovini e in misura minore da suini e bovini. Il prolago è presente in tutti i livelli.In the Grotta Verde, situated at Cape Caccia near Alghero in northern Sardinia, some excavation campaigns have been performed since the fifties of the XX century. It means of an articulated coast cave, with an emerged entrance hall and some submerged rooms. The cave was frequented by man since the early Neolithic to late Neolithic and Chalcolithic periods.
The faunal remains show a predominance of domestic mammals, mainly ovine, and in lower number swine and bovine. Among wild fauna, Prolagus is present in all levels
