Improving the quality of life for people with disabilities through early intervention has been a major focus over the past 20 years. However, much of the direction of intervention has been upon quality of process rather than upon quality of outcome. If early intervention is to have a significant impact upon the lifestyles of people with disabilities, it is important that a longitudinal perspective be adopted and quality of life defined and appropriate measures developed. In this paper a longitudinal perspective on early intervention is discussed along with quality of outcome and programmatic features of quality programs. 相似文献

Given limitations in the integrative scope of past research, basic questions about the organization and development of preschoolers’ living kinds concept remain open to debate. This study was designed to address past limitations through use of a longitudinal design, extensive stimulus set, and alternate indices of understanding. Thirty‐five English‐speaking 3‐year‐olds from middle‐class families in Albuquerque, NM participated in four testing sessions over 1 year. Indices of understanding included statements that preschoolers generated about various living and nonliving objects, biological properties they attributed to the objects, and their characterization of objects as “alive” or not. Results reveal a multifaceted picture of developmental change in preschoolers’ living kinds concept involving both the construction and elaboration of a core biological understanding. 相似文献

This cross-national European comparison examined gender representation and stereotypes in mathematics and language textbooks from Germany, Italy, Lithuania, the Netherlands and Romania. The results showed that female characters were numerically underrepresented. Female characters were also less often a main character or individually portrayed compared to male characters, but not proportionally to the overall lower number of female characters. Characters in occupational roles were less often female than male, whereas among characters with gender non-conform characteristics, these were more often female than male in some textbooks. There was no sexual diversity among characters. The differences in gender representation are found within each country, but gender differences were smaller in more gender-egalitarian countries. If textbooks are to offer the same learning benefits to both boys and girls, students should be equally represented in a diversity of roles and occupations. 相似文献

The present experiments investigated the sunk cost error, an apparently irrational tendency to persist with an initial investment, in rats. This issue is of interest because some have argued that nonhuman animals do not commit this error. Two or three fixed-ratio (FR) response requirements were arranged on one lever, and an escape option was arranged on a second lever. The FRs were of different sizes, and escaping was the behavior of interest. Several variables that might influence the decision to persist versus escape were manipulated: the number of trials with different FR schedules in an experimental session (Exps. 1 and 2), effort to escape (Exp. 2), and the size of the larger FR (Exp. 3). The sunk cost error would result in never escaping, and the optimal strategy would be to escape from the larger FR. The main variable that determined persisting versus escaping was the size of the large FR. Rats that escaped from the large FR-apparently optimal behavior-did so at a suboptimal point, and hence committed the sunk cost error. 相似文献

The purpose of this study was to examine the effects of social praise on the attentive behavior of reinforced and nonreinforced children. Two pairs of mentally retarded preschool boys served as subjects. Employing a reversal design, one child from each pair was differentially reinforced for attending to manipulative toys. The results revealed that: (a) The intervention procedure increased the attentive behavior of the target subjects. (b) Nonreinforced subjects also increased their attentive behavior during both reinforcement conditions. (c) This “spillover” of reinforcement effect was transient, as the non- target subjects level of attentive behavior decelerated during the final half of each 20-day rekforcement period. 相似文献

Inclusive physical education (PE) for students with disability (SWD) evolved in line with ethical requirements and stakeholder morality. While inclusive PE is embraced at a conceptual level and desired at the classroom level, the complexity of successful implementation often remains overlooked in policy and curriculum guidelines. Qualitative studies on inclusive PE are generally small-scale, context-specific and limited in applicability to other settings, while current narrative reviews may indiscriminately select qualitative findings. To overcome existing limitations and extend understanding of world-wide teaching and learning experiences within inclusive PE, we conducted qualitative meta-analysis to systematically synthesise primary qualitative findings into secondary interpretations. First, 7 electronic databases were systematically searched to identify peer-reviewed articles published between 2000 and 2016. Of 672 identified records, 12 met pre-set inclusion criteria. Second, an inductive-deductive hybrid analysis approach revealed two major and eight minor themes. Overall, themes indicated physical educators conceptually embraced inclusive PE with a creative outlook for collaboration, knowledge and support. Cooperative and supportive efforts between physical educators, SWD, parents and teacher aides are valued in creating PE environments that effectively respond to learner diversity. While access to practical teaching guidance remains scarce, this study may contribute to physical educator practice. 相似文献

Understanding genetic drift is crucial for a comprehensive understanding of biology, yet it is difficult to learn because it combines the conceptual challenges of both evolution and randomness. To help assess strategies for teaching genetic drift, we have developed and evaluated the Genetic Drift Inventory (GeDI), a concept inventory that measures upper-division students’ understanding of this concept. We used an iterative approach that included extensive interviews and field tests involving 1723 students across five different undergraduate campuses. The GeDI consists of 22 agree–disagree statements that assess four key concepts and six misconceptions. Student scores ranged from 4/22 to 22/22. Statements ranged in mean difficulty from 0.29 to 0.80 and in discrimination from 0.09 to 0.46. The internal consistency, as measured with Cronbach''s alpha, ranged from 0.58 to 0.88 across five iterations. Test–retest analysis resulted in a coefficient of stability of 0.82. The true–false format means that the GeDI can test how well students grasp key concepts central to understanding genetic drift, while simultaneously testing for the presence of misconceptions that indicate an incomplete understanding of genetic drift. The insights gained from this testing will, over time, allow us to improve instruction about this key component of evolution. 相似文献

Starting with the writer’s own experience as a reader, this article discusses poetry by Eric Roach, Derek Walcott, Linton Kwesi Johnson, John Agard, Edward Baugh, Michael Smith and Velma Pollard. It explores the sense of place felt by writer and reader, going on to analyse the poets’ use of Nation Language, poetic metre and intertextuality in order to create distinctive and authoritative poetic voices. The relationship with the oral tradition and performance is also considered, as is the effect these voices have on a non-Caribbean reader encountering the poems for the first time. The article goes on to present the responses of a class of Year 8 students (12–13-year-olds) who were also reading the poems for the first time, evaluating the extent to which they had moved beyond a tourist’s engagement with the poetry through their study of language, context and performance. Lastly, the article argues for an approach to poetry teaching that recognises the fundamental importance of performance and voice in appreciating Caribbean poetry and considers whether this is possible within the new National Curriculum. 相似文献
