    Occupational Therapy’s Role in the Treatment of Children with Autism Spectrum Disorders

    Get PDF
    Occupational therapists (OT) offer a wide range of therapies for individuals with ASD on the basis of specific deficits and difficulties. This chapter explores the role that OT plays, and the expertise, in relation to the interdisciplinary team. In addition, it discusses and presents empirical support for several therapeutic approaches commonly used by OTs working with individuals with ASD

    Learning the game: Breakdowns, breakthroughs and player strategies

    Get PDF
    Digital games are rich learning environments that require players to engage with challenging situations in order to progress. Recent research indicates that game-play involves overcoming breakdowns and achieving breakthroughs in relation to player action, understanding and involvement. In particular, breakthroughs involve moments of insight where learning occurs which, in turn, can help increase involvement. However, little is known about how players actually achieve breakthroughs. We applied the breakdown/breakthrough “lens” to explore how players attempt to achieve breakthroughs in relation to two single player games. We identified a finite number of strategies that illustrate how players learn in games. These strategies are considered in relation to producing playable and engaging games

    Overview of Instructional Technology Used in the Education of Occupational Therapy Students: A Survey Study

    The purpose of this study was to explore the type of instructional technology (IT) master’s degree level occupational therapy educational programs routinely use as a part of their lecture- and laboratory-based instruction. Surveying the administrators of 121 graduate occupational therapy programs in the United States, we found that the majority of the respondents identified their program as using IT in some form for lecture-based courses, with less inclusion of IT for laboratory-based courses. Hybrid instruction, with the majority of the content being delivered face-to-face and the remainder via online, were the trends among the respondents. The findings also indicated that the respondents’ programs avoid certain IT, including synchronous online chat rooms or instant messaging, digital image collections, blogs or online journaling, Wikis, and audio/video podcasting. Few of the respondents said their programs had made a significant leap into implementing a larger online presence with instructional technology

    Parental cultural models and resources for understanding mathematical achievement in culturally diverse school settings

    Get PDF
    This paper proposes that the theoretical concept of cultural models can offer useful insights into parental involvement in their child’s mathematical achievement and the resources they use to go about gaining information in culturally diverse learning settings. This examination takes place within a cultural-developmental framework and draws on the notion of cultural models to explicate parental understandings of their child’s mathematics achievement and what resources are used to make sense of this. Three parental resources are scrutinized: (a) the teacher, (b) examination test results, and (c) constructions of child development. The interviews with 22 parents revealed some ambiguity around the interpretation of these resources by the parent, which was often the result of incongruent cultural models held between the home and the school. The resources mentioned are often perceived as being unambiguous but show themselves instead to be highly interpretive because of the diversity of cultural models in existence in culturally diverse settings. Parents who are in minority or marginalized positions tend to have difficulties in interpreting cultural models held by school, thereby disempowering them to be parentally involved in the way the school would like

    The Value of Literacy Practices

    Get PDF
    The concepts of literacy events and practices have received considerable attention in educational research and policy. In comparison, the question of value, that is, ‘which literacy practices do people most value?’ has been neglected. With the current trend of cross-cultural adult literacy assessment, it is increasingly important to recognise locally valued literacy practices. In this paper we argue that measuring preferences and weighting of literacy practices provides an empirical and democratic basis for decisions in literacy assessment and curriculum development and could inform rapid educational adaptation to changes in the literacy environment. The paper examines the methodological basis for investigating literacy values and its potential to inform cross-cultural literacy assessments. The argument is illustrated with primary data from Mozambique. The correlation between individual values and respondents’ socio-economic and demographic characteristics is explored

    Comparison of 35 and 50 {\mu}m thin HPK UFSD after neutron irradiation up to 6*10^15 neq/cm^2

    We report results from the testing of 35 {\mu}m thick Ultra-Fast Silicon Detectors (UFSD produced by Hamamatsu Photonics (HPK), Japan and the comparison of these new results to data reported before on 50 {\mu}m thick UFSD produced by HPK. The 35 {\mu}m thick sensors were irradiated with neutrons to fluences of 0, 1*10^14, 1*10^15, 3*10^15, 6*10^15 neq/cm^2. The sensors were tested pre-irradiation and post-irradiation with minimum ionizing particles (MIPs) from a 90Sr \b{eta}-source. The leakage current, capacitance, internal gain and the timing resolution were measured as a function of bias voltage at -20C and -27C. The timing resolution was extracted from the time difference with a second calibrated UFSD in coincidence, using the constant fraction method for both. Within the fluence range measured, the advantage of the 35 {\mu}m thick UFSD in timing accuracy, bias voltage and power can be established.Comment: 9 pages, 9 figures, HSTD11 Okinawa. arXiv admin note: text overlap with arXiv:1707.0496
