The present study examined the construct and predictive validity of a dynamic test of decoding. In theory, a dynamic test provides a direct measure of potential for learning. In this study, children were taught 3 novel letters and how to blend the sounds of those into new words, then they were tested on different words comprising the 3 letters. The study followed 171 children from kindergarten to the end of Grade 1. The dynamic test was found to add significantly to the longitudinal prediction of word reading difficulties at the end of Grade 1 even after controlling for a wide range of standard predictors. The dynamic test correlated strongly with concurrent measures of early reading, letter knowledge, and phoneme awareness but less strongly with vocabulary and nonverbal intelligence. It is suggested that the dynamic test taps learning of sublexical units and processing essential for initial reading development. 相似文献

Crowdsourcing successfully strives to become a widely used means of collecting large-scale scientific corpora. Many research fields, including Information Retrieval, rely on this novel way of data acquisition. However, it seems to be undermined by a significant share of workers that are primarily interested in producing quick generic answers rather than correct ones in order to optimise their time-efficiency and, in turn, earn more money. Recently, we have seen numerous sophisticated schemes of identifying such workers. Those, however, often require additional resources or introduce artificial limitations to the task. In this work, we take a different approach by investigating means of a priori making crowdsourced tasks more resistant against cheaters. 相似文献

In the face of accelerating technological, demographic, socioeconomic, and political changes, successful organizations are flattening hierarchies, forging active communication networks, promoting cross‐functional and cross‐level collaboration, and actively supporting grassroots innovation. Traditional performance management practices lack the capacity, scalability, and speed to support these cultural strategies. This article describes a new breed of performance management: an appreciative inquiry‐inspired process that focuses on strengths and puts employees in the driver's seat. It increases commitment and forges trusting relationships between employees and their leaders and paves the way for the next generation of performance management systems. 相似文献

The increasing dominance of educational markets means that quality of higher education has the character of open signifiers of periodic occurrence, embedded institutionally as ways of consensual communication on how to go on as smoothly as possible. This promotes the growth of context dependent and local interpretations of how to meet in agreement regarding quality in everyday practices. All interpretations are contextualised and as a result are nullified outside the context in which they occur. Discourses on quality promote flexibility and create periodic legitimacy through discursive nullification processes. On the other hand, institutions have to adopt standards in education as a measure of outcome indicators for benchmarking. When quality is replaced by standards and if standards are equivalent to labour market relevance this might signal the beginning of overall external control over higher education. In the long run it will hardly benefit educational programmes if institutions of higher educations fail to ‘stand for’ quality that, in the very least, can supplement the fulfilment of politically determined targets and standards. In this way the market will have not only graduates who are going into employment but also engaged citizens who can transform and challenge the market. 相似文献

Although many professionals in education believe that an ‘objects first’ approach is the best method of introducing object-oriented technology, there is no common agreement on how to start such courses. Current study programs often begin by teaching a chosen object-oriented programing language, where students are confronted by a large amount of syntactical detail. Instead of focusing on the basics of object-oriented technology, namely objects and their collaborations, difficulties in handling the details of the programing language lead to a very scattered knowledge of object-oriented concepts. This is dangerous, as learners are left with a set of unconnected knowledge fragments. Approaches which embed different knowledge fragments in an overall knowledge view are known as “cognitive apprenticeship” approaches. The main idea of cognitive apprenticeship is continuous practice. We present a learning environment for introducing object-oriented technology in upper secondary schools based on cognitive apprenticeship. We use a visual programing language to away from the details and provide tool support to aid practice. We present the learning sequencewhich is used and show the impacts it makes on the course structure in our experiment in the chosen object-oriented programming language The Joint Task Force on Computing Curricula IEEE Computer Society. 相似文献

This study compares student perceptions, learning behaviours and success in online and face-to-face versions of a Principles of Microeconomics course. It follows a Scholarship of Teaching and Learning (SoTL) approach by using a cycle of empirical analysis, reflection and action to improve the learning experience for students. The online course design involves 58 interactive narrated online modules, interactive online quizzes and biweekly online meetings with the instructor via video and voice-over-IP technology. Findings indicate that schedule flexibility motivates students to choose the online course format. Students in both learning environments felt they had high-quality communication with the instructor, while online students indicated limited peer-to-peer communication. Online students report studying more at home than face-to-face students, but not enough to compensate for the time face-to-face students spend in class. Reflecting on the findings, the authors suggest actions to improve the online course experience. 相似文献

This article reports data from a training study of morphological awareness involving 33 dyslexic students in grades 4 - 5. The dyslexic students received 36 lessons of morphological awareness training each of about a quarter of an hour. The training was oral and focused on semantic aspects of morphemes. During the training period, the experimental group gained significantly more than a similar group of untrained controls (n = 27) on one of three measures of morphological awareness. Both groups, however, made equal gains on measures of phonological awareness, phoneme discimination and picture naming. The experimental group progressed significantly more than the controls in reading comprehension and in spelling of morphologically complex words. The results of the study suggest that it is possible to develop dyslexic students' morphological awareness. Furthermore, awareness of morphemes, the smallest meaningful units of language, may support the development of meaning - oriented decoding strategies in reading and spelling. 相似文献

Failure to activate relevant, existing background knowledge may be a cause of poor reading comprehension. This failure may cause particular problems with inferences that depend heavily on prior knowledge. Conversely, teaching how to use background knowledge in the context of gap-filling inferences could improve reading comprehension in general. This idea was supported in an experimental study comprising 16 sixth-grade classes (N?=?236) randomly assigned to experimental or control conditions. In the experimental condition, students' contribution to “gap-filling” inferences with expository texts were made explicit by means of graphic models and inference-demanding questions. After eight 30-min sessions, a large training effect was found on students' inference making skills with a substantial and sustained transfer effect to a standard measure of reading comprehension. The effects were not mediated by students' motivation, decoding ability, vocabulary, or nonverbal IQ. 相似文献
