    MOOC adaptation and translation to improve equity in participation

    Get PDF
    There is an urgent need to improve elementary and secondary school classroom practices across India and the scale of this challenge is argued to demand new approaches to teacher professional learning.  Massive Open Online Courses (MOOCs) represent one such approach and which, in the context of this study, is considered to provide a means by which to transcend traditional training processes and disrupt conventional pedagogic practices. This paper offers a critical review of a large-scale MOOC deployed in English, and then in Hindi, to support targeted sustainable capacity building within an education development initiative (TESS-India) across seven states in India.  The study draws on multiple sources of participant data to identify and examine features which stimulated a buzz around the MOOCs, leading to over 40,000 registrations and a completion rate of approximately 50% for each of the two MOOCs

    Impact of Argument Type and Concerns in Argumentation with a Chatbot

    Get PDF
    Conversational agents, also known as chatbots, are versatile tools that have the potential of being used in dialogical argumentation. They could possibly be deployed in tasks such as persuasion for behaviour change (e.g. persuading people to eat more fruit, to take regular exercise, etc.) However, to achieve this, there is a need to develop methods for acquiring appropriate arguments and counterargument that reflect both sides of the discussion. For instance, to persuade someone to do regular exercise, the chatbot needs to know counterarguments that the user might have for not doing exercise. To address this need, we present methods for acquiring arguments and counterarguments, and importantly, meta-level information that can be useful for deciding when arguments can be used during an argumentation dialogue. We evaluate these methods in studies with participants and show how harnessing these methods in a chatbot can make it more persuasive

    Providing Comprehensive Educational Opportunity to Low-Income Students. Part 4: What Are the Social and Economic Returns?

    Approximately half of all New York City public school students who live in families with incomes less than 185% of the federal poverty level (FPL) do not graduate from high school. These dropouts are much less likely to achieve economic self-sufficiency in adulthood. This creates both a fiscal and social burden. Rothstein, Wilder and Allgood (2011) propose a set of publicly funded comprehensive services to supplement academic services that could effectively raise the educational attainment levels of low income children to levels associated with middle class children. This report, the fourth in a five part feries, calculates the fiscal and social impact of raising the attainment levels of these students in order to assess whether the costs of such services are justified by the benefits. Specifically, the report estimates the economic costs and benefits attributable to a single cohort of 37,000 12th grade students from families with incomes below 185% FPL who are currently finishing up in New York City public schools. It calculates the net fiscal contributions by education level per individual. These contributions are tax revenues, minus government expenditures on healthcare, the criminal justice system, welfare programs, and school/college. The report finds that New York City and State combined spend 82,000(inlifetimepresentvalueterms)oneachhighschooldropoutonhealthcare,criminaljustice,welfare,andeducationwhilereceivingonly82,000 (in lifetime present value terms) on each high school dropout on healthcare, criminal justice, welfare, and education while receiving only 45,000 in tax revenues.

In contrast, for students earning a BA or higher degree, the city and state expenditures amount to 55,000 while tax revenues are 143,000,resultinginabalanceof143,000, resulting in a balance of 88,000 in favor of the government. The impact for the federal government is also substantial with high school dropouts costing 1,360whenfederalexpendituresarenettedagainstfederaltaxrevenues,whilestudentsearningaBAorhigherdegreecontribute1,360 when federal expenditures are netted against federal tax revenues, while students earning a BA or higher degree contribute 347,460 in lifetime present value terms. Evidently dropouts create a greater fiscal burden for the state and city than for the federal government, but the federal government gains dramatically more as education levels increase. The economic analysis provided in this report indicates that provision of all support programs in the comprehensive approach outlined by Rothstein, Wilder, and Allgood (2011) would require a significant outlay by state and local governments above and beyond what is currently expended. However, the resulting estimated 9% rate of return on investment compares favorably with existing forms of government debt, suggesting that a feasible strategy would be to finance the costs of a comprehensive support program for low-income children through the issuance of long-term municipal bonds. Philanthropic foundations could also help fund these social investments by providing grants to service providers that would be replaced by public funds if target outcomes were met

    Who uses drug checking services? Assessing uptake and outcomes at English festivals in 2018

    Get PDF
    Purpose This study aims to assess service user characteristics, uptake and outcomes for drug checking services offered to over 250,000 English festival-goers in summer 2018 and to compare findings with earlier years, wider festival-goers and the general population. Design/methodology/approach A total of 2,672 substances of concern were submitted by the public and tested by chemists in mobile laboratories on 24 show days at seven festivals. Results were embedded in 2,043 individually tailored brief interventions (BI) delivered by health professionals to 4,240 service users. Comparative data were collected through anonymous self-report surveys with 1,291 respondents at five of the same festivals. Findings Three percent of drug-using festival-goers received BI, 95% of whom had not previously accessed health services regarding their alcohol or other drug use. Drug checking service users were significantly more likely to be younger, male and past month polydrug users with a wider range of drugs consumed in the last month compared with the general festival population. For samples matching purchase intent, nearly half intended to reduce dosage, with younger and female service users significantly more likely to reduce dosage. For substances identified as other than expected, nearly two thirds disposed of them. Social implications Festivals are potential sites to deliver innovative health interventions and to monitor their outcomes, reduce the risk of poisoning and overdose, and facilitate access to follow-up support services. Originality/value This study suggests that there is value in event-based services that provide risk reduction communications directly to young adults engaged in higher risk drug use compared with wider event and general populations. </jats:sec

    Single- and double-scattering production of four muons in ultraperipheral PbPb collisions at the Large Hadron Collider

    Full text link
    We discuss production of two μ+μ−\mu^+\mu^- pairs in ultraperipheral ultrarelativistic heavy ion collisions at the LHC. We take into account electromagnetic (two-photon) double-scattering production and for a first time direct γγ\gamma\gamma production of four muons in one scattering. We study the unexplored process γγ→μ+μ−μ+μ−\gamma \gamma \to \mu^+\mu^-\mu^+\mu^-. We present predictions for total and differential cross sections. Measurable nuclear cross sections are obtained and corresponding differential distributions and counting rates are presented.Comment: 13 pages, 11 figures, 1 tabl

    Cost-Effectiveness Analysis of Early Reading Programs: A Demonstration With Recommendations for Future Research

    Get PDF
    We review the value of cost-effectiveness analysis for evaluation and decision making with respect to educational programs and discuss its application to early reading interventions. We describe the conditions for a rigorous cost-effectiveness analysis and illustrate the challenges of applying the method in practice, providing examples of programs for which we have estimated costs, but find effectiveness data lacking in comparability. We provide a demonstration of how cost-effectiveness analysis can be applied to two early reading programs: the Wilson Reading System and Corrective Reading. We use existing effectiveness data from an experimental evaluation in which the programs were implemented under similar conditions and the use of common outcomes measures for both programs yielded data that are comparable. We combine these data with cost data we collected using the ingredients method to calculate cost-effectiveness ratios for the alphabetics domain. A complete picture of the relative cost-effectiveness of each program could be provided if effectiveness metrics were available for fluency, vocabulary, and comprehension. We highlight the obstacles to applying cost-effectiveness analysis more frequently and recommend strategies for improving the availability of the requisite data
