The purpose of this study was to investigate whether there is some factor or set of factors which will predict the probability of graduation from doctoral programs. This study concentrated on two areas: (a) the factors available to the selection committee when the students apply for admission into graduate programs, and (b) those factors emerging after admission, resulting from the students' meeting program-imposed requirements for graduation. Data were collected from the file of each student admitted to the doctoral program in Educational Administration. The results of the study indicated that program variables are more important than admission variables in predicting graduation. and the technique of Path Analysis is highly recommended to study the problem of student progression through graduate departments. 相似文献

Infant vocalizations are early-emerging communicative markers shown to be atypical in autism spectrum disorder (ASD), but few longitudinal, prospective studies exist. In this study, 23,850 infant vocalizations from infants at low (LR)- and high (HR)-risk for ASD (HR-ASD = 23, female = 3; HR-Neg = 35, female = 13; LR = 32, female = 10; 80% White; collected from 2007 to 2017 near Philadelphia) were analyzed at 6, 12, and 24 months. At 12 months, HR-ASD infants produced fewer vocalizations than HR-Neg infants. From 6 to 24 months, HR-Neg infants demonstrated steeper vocalization growth compared to HR-ASD and LR infants. Finally, among HR infants, vocalizing at 12 months was associated with language, social phenotype, and diagnosis at age 2. Infant vocalizing is an objective behavioral marker that could facilitate earlier detection of ASD. 相似文献

This paper examines a theoretical perspective on the ways in which children progress in learning mathematics. It suggests that there is a difficulty in associating teaching discourses with the mathematics they locate. This can result in an incommensurability between alternative perspectives being offered. The paper resists attempts to privilege any particular account but rather demands an analysis of these discourses and their presuppositions. In developing these themes the paper invokes Ricoeur's analysis of time and narrative as an analytical approach to treating notions such as transition, development and progression in mathematical learning. His notion of semantic innovation is introduced. This embraces both the introduction of a new metaphor into a sentence or the creation of a new narrative which reorganises events into a new plot. The notion is utilised in arguing that the shift in the student's mathematical development from arithmetic to first order linear equations with unknowns reconfigures the contextual parameters governing the understanding of these mathematical forms. It is also utilised in showing how alternative approaches to accounting for such transitions suit different and perhaps conflicting outcomes. For example, demonstrating awareness of generality or performing well in a diagnostic test featuring the solution of linear equations.This revised version was published online in September 2005 with corrections to the Cover Date. 相似文献

ABSTRACTBackground: Over the past 10 years, research has started to investigate the pedagogic practices of instructors and coaches working in adventure sports settings. Outdoor instructors face particular challenges regarding the impact the dynamic environment has on the coaching process and their students. This challenging combination of factors obliges the instructor to be agile in response. We propose that this adaptive expertise is characteristic of these factors and that adaptability may be a beneficial focus of outdoor instructor training and education.Purpose: The major aim was to identify if adaptive expertise is an attribute of outdoor instructors? And if so, what are its characteristics in this context?Research design and data collection: We applied a mixed methodology to a sample of outdoor instructors (n?=?64). The instructors were asked to complete a quantitative adaptive expertise inventory. We then interviewed a selected sub-sample (n?=?12).Participants and setting: Quantitative data was collected from outdoor instructors working in the UK (n?=?64). The sample consisted of instructors qualified to work independently with groups in adventurous settings in a range of activities. Qualitative data was collected from a smaller sample (n?=?12) via a series of thematically analysed semi-structured interviews.Findings: Results suggest that the participating outdoor instructors have high levels of adaptive expertise. A characteristic of that adaptive capacity is a combination of skills revolving around reflection, metacognition, and situational awareness. There were differences, however, between less and more experienced outdoor instructors in their adaptive capacity, with less experienced instructors being adaptive to a lesser extent.Conclusions: The implication is that further research is worthwhile to examine the development of instructors’ adaptive capacity. The training and education of outdoor instructors requires pedagogic approaches that facilitate and engender adaptability, flexibility and agility in neophyte instructors. 相似文献

This study investigates the effects of methylphenidate (Ritalin) on hyperactive children's performance on a paired-associate learning task under 3 presentation rates (4, 8, and 12 sec per item). The total-time hypothesis states that a fixed amount of time is necessary to learn a fixed amount of material, regardless of the number of trials into which that time is divided. In a double-blind crossover design, the total-time hypothesis was supported by performance in a drug state, but not by performance in a placebo state, where slower presentation rates were not utilized effectively. These results are discussed in terms of inattention in the placebo state and improved attention and use of learning time in the drug state. The methodology presented is suggested as a means of assessing attentional deficits as well as providing a diagnostic procedure for objectively evaluating the appropriateness of stimulant treatment for children referred for symptoms of hyperactivity. 相似文献

This article continues a theme of previous investigations by the authors and examines the focus of in-action reflection as a component of professional judgement and decision-making (PJDM) processes in high-level adventure sports coaching. We utilised a thematic analysis approach to investigate the decision-making practices of a sample of high-level adventure sports coaches over a series of sessions. It was discovered that adventure sports coaches utilise a combination of questioning and observation to collect and constantly verify the information that forms the basis of their PJDM. Each coach responds to matters of immediate security, collecting information until a best-fit decision can be made regarding changes to the environment, task or individual. Implications for professional training, accreditation and development are presented against these data, offering a template for a more expertise-focused progression in the adventure sports coaching profession. 相似文献
