Preparing student teachers for Teaching Practice: early placements in Initial Teacher Education

This paper reports a pilot project of ten initial teacher training students engaged on a three-year undergraduate programme leading to BA(hons) in English with QTS. In the first two years of their programme, student teachers normally receive academic input only, embarking on a one-year practicum stage in the third year of their programme. The project allowed student teachers to become closely associated with one of the University’s partnership schools to enable them to understand the daily life in schools and begin to engage with teaching. In addition they used secure social networking through the Mahara e-portfolio system to exchange ideas and experiences. The project proved highly successful in reducing isolation, enhancing communication and it helped student teachers to decide which kind of school they wished to work with in the future

Unbearable Burden? Living and Paying Student Loans as a First-Year Teacher

It is widely believed that starting public school teacher salaries are too low, and student loan burdens are too high. If true, we could be facing a situation in which recent college graduates cannot afford to go into teaching because they will be unable to repay their college debts. Public policies are already being formulated on the basis of that conclusion. Unfortunately, the only major analysis of teacher salaries and student debt published to date is based largely on borrowers' subjective feelings about debt manageability. Likewise, more traditional methods of determining how much debt is too much offer little help because they are based primarily on general risks of default predicted by debt-to-income ratios rather than the ability of specific borrowers to handle their debts and other expenses. To provide legislators with a more objective basis for policymaking, this paper assesses first year teachers' ability to pay back college loans given their actual salaries and expenses. This method eliminates both the subjectivity of determining debt burdens on the basis of debtors' feelings, and the imprecision of using correlations between debt-to-income ratios and overall default rates. The findings presented here reveal that first year teachers in even the least affordable of the 16 districts examined can easily afford to pay back their debts. Indeed, with just some basic economizing, a first-year teacher could not only pay back average debt, but could handle debt levels nearly three times the national average. This does not mean that current teacher salaries or student debt burdens are "right" -- only markets can determine that -- but it does mean that there is no need for policymakers to intervene in either teacher pay or student aid to assure that college graduates can afford to become public school teachers

Simulation based sequential Monte Carlo methods for discretely observed Markov processes

Parameter estimation for discretely observed Markov processes is a challenging problem. However, simulation of Markov processes is straightforward using the Gillespie algorithm. We exploit this ease of simulation to develop an effective sequential Monte Carlo (SMC) algorithm for obtaining samples from the posterior distribution of the parameters. In particular, we introduce two key innovations, coupled simulations, which allow us to study multiple parameter values on the basis of a single simulation, and a simple, yet effective, importance sampling scheme for steering simulations towards the observed data. These innovations substantially improve the efficiency of the SMC algorithm with minimal effect on the speed of the simulation process. The SMC algorithm is successfully applied to two examples, a Lotka-Volterra model and a Repressilator model.Comment: 27 pages, 5 figure

The Redactor

Artist Publication. Printed for and commissioned by Antony Hudek for the exhibition 'The Incidental Person' at Apexart, New York, 2010. One of a series of artist publications produced by Office of Experiments. The publication represents research into autonomous forms of research and individual artists dealing with research outside of institutions. In many cases this work seeks to examine information that has been censored or redacted, generating speculation and evidence as it does so . Artist were selected on the basis that they create their own structures - such as Rich Pell and his Center for Post Natural History. Office of Experiments is another example of this. Other featured researchers were involved with Office of Epxeriments own research projects and occupy a contested space between official research and secrecy. All have questioned the authenticity of institutions in relation to knowledge and the work is set in the context of institutional critique. The research reflects Whites work as a former Director of O+I, the group which took over from the Artist Placement Group and on whose ideas Antony Hudek used for the exhibition 'The Incidental Person'

Automated Detection of Solar Eruptions

Observation of the solar atmosphere reveals a wide range of motions, from small scale jets and spicules to global-scale coronal mass ejections. Identifying and characterizing these motions are essential to advancing our understanding the drivers of space weather. Both automated and visual identifications are currently used in identifying CMEs. To date, eruptions near the solar surface (which may be precursors to CMEs) have been identified primarily by visual inspection. Here we report on EruptionPatrol (EP): a software module that is designed to automatically identify eruptions from data collected by SDO/AIA. We describe the method underlying the module and compare its results to previous identifications found in the Heliophysics Event Knowledgebase. EP identifies eruptions events that are consistent with those found by human annotations, but in a significantly more consistent and quantitative manner. Eruptions are found to be distributed within 15Mm of the solar surface. They possess peak speeds ranging from 4 to 100 km/sec and display a power-law probability distribution over that range. These characteristics are consistent with previous observations of prominences.Comment: 6 pages, 4 figures, 7th Solar Information Processing Workshop, to appear in Space Weather and Space Climat
