To examine current practices in the use of psychoeducational evaluations for service delivery, we surveyed 91 service providers to college students with learning disabilities. The three purposes of the survey were to determine (a) whether service delivery decisions are based on information from psychoeducational evaluations, (b) which sections of the psychoeducational report are most useful in making service delivery decisions, and (c) the respondents' satisfaction with the tests and measurements for service delivery. The findings supported the common belief that data from psychoeducational evaluations serve as the primary basis for both eligibility and specific accommodation determinations. Respondents reported that all sections of the psychoeducational evaluation written report were useful, with the least useful section being test scores and the most useful being the summary of cognitive strengths and weaknesses. However, the section used most often for service delivery decisions was the professional's recommendations. 相似文献

In this paper, decomposition methods for multidimensional data hypercubes of OLAP systems are investigated. Criteria for reducing the computational complexity of the decomposition methods are presented and comparisons are made with the traditional solutions of multidimensional data analysis problems. Examples illustrating the application of these criteria to investigating the dynamics of computational complexity changes for specific types of reduction problems are considered. 相似文献

Nano-sized molecular motors, which consume chemicals and do mechanical work are ubiquitous in nature. One of the most powerful
such motors is the viral packaging motor, which consumes ATP and packages the viral DNA into the procapsid (the protein shell)
of the virus. A pulling force applied to the loose end of the DNA can slow down the rate of packaging, thus showing that a
mechanical force can slow down a chemical reaction. In this article we describe this packaging process and what is known about
the mechanochemistry of the motor.

A survey conducted at three Florida library systems examines caregivers' perceptions of emergent literacy programming and how these perceptions compare with the National Research Council's features for quality programs for children. The survey results reveal that caregivers' perceptions of emergent literacy programming align with the National Research Council's features. The data demonstrates that caregivers' perceptions are very positive toward emergent literacy programming in terms of learning and the environment. Caregivers' perceptions of the environment answers were mostly strongly agree. These results were more positive than their perceptions of learning, although they strongly agree that these programs prepare children for school, reading, and social interaction. The survey results will inform public libraries as to how to design, market, and deliver emergent literacy programming to caregivers with very young children. 相似文献

Prelinguistic babbling often seems remarkably speech-like, not because it has recognizable words but because it seems to have adult-like prosody. To quantify this impression, we compared disyllabic sequences from five infants and five adults in terms of the use of frequency, intensity, and duration to mark stress. Significantly larger values for the three acoustic variables were observed on stressed than on unstressed syllables independent of syllable position for both groups. Adults showed the correlates of utterance final syllables--lower f0, lower intensity, and longer duration; infants showed only decrease in intensity. Ratios for stressed to unstressed syllables and participation of the three variables in stress production in individual disyllables were highly similar in both groups. No bias toward the English lexical trochaic stress pattern was observed. We conclude that infants in English environments produce adult-like stress patterns before they produce lexical items, which specify stress. Acoustic and perceptual analyses are used to explore stress marking by prelinguistic infants in an English language environment. Results show that infants employ the three acoustic correlates of stress in individual syllables in a manner largely similar to that of adult speakers, although they do not show second-syllable declination effects or an English language trochaic stress bias. 相似文献

The big-fish–little-pond effect (BFLPE) predicts that equally able students have lower academic self-concepts (ASCs) when
attending schools where the average ability levels of classmates is high, and higher ASCs when attending schools where the
school-average ability is low. BFLPE findings are remarkably robust, generalizing over a wide variety of different individual
student and contextual level characteristics, settings, countries, long-term follow-ups, and research designs. Because of
the importance of ASC in predicting future achievement, coursework selection, and educational attainment, the results have
important implications for the way in which schools are organized (e.g., tracking, ability grouping, academically selective
schools, and gifted education programs). In response to Dai and Rinn (Educ. Psychol. Rev., 2008), we summarize the theoretical model underlying the BFLPE, minimal conditions for testing the BFLPE, support for its robust
generalizability, its relation to social comparison theory, and recent research extending previous implications, demonstrating
that the BFLPE stands up to scrutiny.

Until recently, no self‐report instruments have examined psychological skills use in both practice and competition. In light of the significant role of practice in sport performance outcomes, a need exists to measure these skills in both domains. This study was designed to investigate differences in performance strategies of US Olympians in both practice and competition. The Test of Performance Strategies was administered to 176 US participants in the 2000 Sydney Olympic Summer Games. Discriminant function analyses demonstrated significant differences between medalists and nonmedalists in both the competition and practice performance strategies. Furthermore, significant gender and age differences were identified for competition strategies only. The 16 subscales of the TOPS, with two exceptions, create an internally stable instrument with moderate predictive ability relative to quality of sport performance, gender, and age in this elite sample of athletes. 相似文献

This study attempts to identify the factors perceived to be important in choosing an Institution of Higher Learning (IHL) for distance learning. One thousand five hundred questionnaires were distributed to the first year students in the social sciences distance learning programs and 980 valid responses were received of Malaysian public university. The results show that the top three factors influencing their preferred institution are qualification recognition IHL, future career advancement, and personal satisfaction. The results of this study provide insights to the IHL, employers and academics on the nature and relative importance of the factors perceived important for adult learners in the selection of their preferred IHL. 相似文献

In this study, the use of inquiry methods, learning cycles, a conceptual change model and analogy in creating alternative
science texts was discussed. An alternative text on the topic of acids and bases was created by integrating the methods and
models discussed in this paper. The alternative text and a sample of a traditional text taken from a textbook, which is still
used in Turkish high schools, were given to two groups, totaling 42 pre-service teachers—the alternative text was given to
an experimental group and the traditional text to a control group—in an experimental setting and their understandings of acids
and bases were compared. In addition, in the second step of the study, the pre-service teachers read both texts and indicated
their preferences in terms of interest, understandability and helpfullness. 相似文献
