In this paper, we advocate the use of the microgenetic method, a methodology that combines dense sampling of observations across time and extensive trial-by-trial analysis, to examine strategy change in children with disabilities. This methodology has revealed new information about normally achieving children's cognition, such as large individual variability in strategy use among children of the same age and more gradual patterns of strategy change than previously assumed. In this paper, we review data from three different microgenetic studies in the domains of memory, arithmetic, and reading with children with or at risk for mental retardation and normally achieving children. Our review indicates that there are similar sequences of strategy change, similar rates of strategy change, and similar frequency of strategy discovery and use in children with and without mental retardation (compared to mental age peers). Implications are discussed for the use of this methodology to design instructional techniques for children with disabilities.  相似文献

The problem was to determine how rats adjust the times of their lever responses to repeating sequences of interfood intervals. In Experiment 1, rats were trained on an interval schedule of reinforcement with a 12-element Fleshler-Hoffman series with a mean of 60 sec; the order was as follows: ascending, random with repetition, random with replacement, random without replacement. In Experiment 2, rats were trained with a 10-element ascending or descending series (from 20 to 29 sec), and in a ramp procedure in which these intervals increased and then decreased repeatedly. In the ascending, descending, and ramp conditions (but not in the random conditions), postreinforcement pause (PRP) was a function of the interval. PRP was most highly correlated with an interval later in the series. Theories of conditioning and timing based on the averaging of past experience must be modified to account for such anticipatory behavior.  相似文献

Learning the fundamentals of probability and random variables can be a struggle for many students. Games by their nature require active participation and reward mastery, lending naturally to the framework of active learning. In this study, we designed and evaluated the efficacy of a lab activity using a game where strategy hinges on sums of dice to teach about linear combinations of independent random variables. We found that both activities lead to improved understandings of course concepts, but the dice game provided increased student engagement and interest.  相似文献

With the creation of interactive tasks that allow students to explore spatial ways of knowing in conjunction with their other ways of knowing the world, we create a space where students can make sense of information as they organize these new ideas into their already existing schema. Through the use of a Common Online Data Analysis Platform (CODAP) and data from Public Use Microdata Areas (PUMA), students can explore the communities in which they live and work, critically examining opportunities and challenges within a defined space.  相似文献

Through reflection on the First International iPED Conference 2006, and its overarching theme of ‘Pedagogical Research and Academic Identities’, this paper considers the achievement of the wider aims of the conference, which were to facilitate dialogue between researchers in order to explore the conference themes collaboratively, and to provide networking opportunities which would enable participants to build alliances. The abstracts for all papers mentioned are available via the conference website www.coventry.ac.uk/iped2006.  相似文献

ABSTRACT

This paper explores the emotional experiences of elementary school inspections, from the appointment of the first State school inspectors in 1839 to 1911 when Edward Holmes, the retiring chief inspector, signposted the prospects of a new era in elementary education. The paper is arranged in two parts: the first provides an outline of the origins and development of elementary school inspection, while the second discusses the potential contribution of emotions scholarship to inform our understanding of elementary schooling seen through the lens of inspection. Whereas previous studies have concentrated on the inspectorate’s administrative history in relation to school development, this paper’s contribution is to highlight what inspection sources reveal about elementary schools as sites of emotional expression and experience. While acknowledging the challenges a history of emotions framework presents, the paper concludes that such an approach offers a fresh perspective on inspection and school regimes in the past.  相似文献

Despite mixed results in research on student learning from drawing in science, there is growing interest in the potential for this visual mode, in tandem with other modes, to enact and enable student reasoning in this subject. Building on current research in this field, and using a micro-ethnographic approach informed by socio-semiotic perspectives, we aimed to identify how and why student drawing can contribute to student reasoning and learning. In our study, secondary school students were challenged to explore and collaboratively create explanatory representations of phenomena including through drawing. Data were generated using multiple wall- and ceiling-mounted cameras capable of continuously tracking groups of students negotiating these representational challenges. Our analysis proceeded through active and iterative viewing of the extensive video record, and the identification of themes to establish possible relationships between drawing and reasoning. Through this process, we (a) identify multiple necessary conditions and varied opportunities for student drawing to enact and enable reasoning, and (b) extend current understandings of how the particular affordances of this mode interact with these conditions to contribute to student learning in science.  相似文献
