The primary goal of this research was to extend our understanding of the strengths and weaknesses inherent in online and offline early literacy software programs designed for young learners. A taxonomy of reading skills was used to contrast online software with offline closed system (compact disc) based programs with respect to number of skills taught, quality of instruction and scaffolding during instruction. Overall, online programs were more comprehensive and provided instruction for more skills than offline software at either the Kindergarten or Grade 1 level. However, offline programs demonstrated some developmentally appropriate selectivity in skills trained. Quality of instruction was variable within and across all programs. Scaffolding of instruction was also variable and surprisingly few programs, either online or offline, provided automatic movement across levels of difficulty. These outcomes have important implications for the selection of instructional materials by parents and educators involved in early literacy instruction and also for future software design.  相似文献

This paper presents a systematic literature review of academic staff experiences and perceptions of adopting Technology for Assessment OF/FOR/AS Learning in Higher Education. This paper is a qualitative synthesis of 65 peer-reviewed journal articles published between 2012 and 2017 reporting on the use of technology for assessment (TfA). The results suggest that there are some efficiencies for staff in implementing TfA but this can come with a cost at the set-up and maintenance phases. Furthermore, results indicated that assessment design is not of foremost concern to academic staff when introducing TfA, but that a wide variety of pressures and both educational and operational drivers are present. There were inconclusive findings in relation to understandings of appropriate institutional environments and supports for TfA to flourish in higher education. There is a need for empirical research, particularly longitudinal investigations, of academic experiences of implementations of TfA to investigate sustainability of adoption. The imperative of exploring the academic staff perspective as the instigator and manager of both the technology and the student learning experience requires deep consideration as TfA adoption progresses.  相似文献

Abstract

The aim of this study was to develop a performance test set-up for America's Cup grinders. The test set-up had to mimic the on-boat grinding activity and be capable of collecting data for analysis and evaluation of grinding performance. This study included a literature-based analysis of grinding demands and a test protocol developed to accommodate the necessary physiological loads. This study resulted in a test protocol consisting of 10 intervals of 20 revolutions each interspersed with active resting periods of 50 s. The 20 revolutions are a combination of both forward and backward grinding and an exponentially rising resistance. A custom-made grinding ergometer was developed with computer-controlled resistance and capable of collecting data during the test. The data collected can be used to find measures of grinding performance such as peak power, time to complete and the decline in repeated grinding performance.  相似文献

Librarians and faculty members are now working together through Open Access (OA) publishing to make faculty-produced scholarly content available to researchers worldwide. The University of South Florida Tampa Library has been working with the Berkeley Electronic Press (bepress) Digital Commons platform to create a substantial institutional repository (IR) that includes OA journals, conference proceedings, and data sets, among other materials. Library staff members are currently involved in a variety of activities, including negotiating memoranda of understanding, loading backfiles, registering Digital Object Identifiers (DOIs) with CrossRef, designing layout, doing final publication steps, and assisting with technical issues. In 2011, the IR, Scholar Commons @ USF, went live, allowing the library to pull fragmented collections previously hosted on other platforms into a single system with improved discoverability. This article discusses how the repository was established, what is involved, lessons learned, and plans for future directions.  相似文献

There is widespread consensus in the research and policy‐related literature over the last decade that young people who have been permanently excluded from school are at a far greater risk of a variety of negative outcomes than young people who have not had this experience. These negative outcomes include prolonged periods out of education and/or employment; poor mental and physical health; involvement in crime; and homelessness. This article presents evidence from a small‐scale qualitative study of destinations and outcomes post‐exclusion for a group of young people considered to be at particular risk of such negative outcomes: namely, those who have been permanently excluded from special schools or Pupil Referral Units (now known as short‐stay schools). The specific focus of this paper is on the 24 young people's educational trajectories pre‐ and post‐exclusion; the reasons for their exclusion from school; and on what forms of alternative provision were available to them after their permanent exclusion.  相似文献

College undergraduates read a 2400-word passage, responded to 16 multiple-choice questions, and received one of four types of feedback following their responses. Complexity of feedback was inversely related to both error correctability and criterion efficiency taken as a ratio of feedback study time to post-test corrects. The results were discussed in terms of depth of processing and instructional comprehension.  相似文献

Biomimetic scaffolds approaching physiological scale, whose size and large cellular load far exceed the limits of diffusion, require incorporation of a fluidic means to achieve adequate nutrient/metabolite exchange. This need has driven the extension of microfluidic technologies into the area of biomaterials. While construction of perfusable scaffolds is essentially a problem of microfluidic device fabrication, functional implementation of free-standing, thick-tissue constructs depends upon successful integration of external pumping mechanisms through optimized connective assemblies. However, a critical analysis to identify optimal materials/assembly components for hydrogel substrates has received little focus to date. This investigation addresses this issue directly by evaluating the efficacy of a range of adhesive and mechanical fluidic connection methods to gelatin hydrogel constructs based upon both mechanical property analysis and cell compatibility. Results identify a novel bioadhesive, comprised of two enzymatically modified gelatin compounds, for connecting tubing to hydrogel constructs that is both structurally robust and non-cytotoxic. Furthermore, outcomes from this study provide clear evidence that fluidic interconnect success varies with substrate composition (specifically hydrogel versus polydimethylsiloxane), highlighting not only the importance of selecting the appropriately tailored components for fluidic hydrogel systems but also that of encouraging ongoing, targeted exploration of this issue. The optimization of such interconnect systems will ultimately promote exciting scientific and therapeutic developments provided by microfluidic, cell-laden scaffolds.  相似文献

This study investigated development of the Big Five personality traits from early childhood into adulthood. An initial group of 137 Swedish children were assessed eight times between ages 2 and 29 years. Initial decreases in extraversion leveled off in early adulthood; agreeableness and conscientiousness increased from ages 2 to 29; neuroticism initially increased, leveled off in later childhood and adolescence, and decreased throughout early adulthood; while openness to experience showed an initial increase, then decreased and leveled off in early adulthood. Individual developmental trajectories varied significantly, particularly in relation to gender. Personality traits became increasingly stable, and the fact that childhood scores predicted scores in adulthood indicated that personalities are fairly stable across this portion of the life span.  相似文献
