There is a vast literature on the decision to enroll in higher education, but it focuses almost entirely on traditional students: 18 year olds graduating from high school. Yet less than half of students at degree-granting institutions are in the traditional 18–22 age range; nearly 40% are at least 25. This paper examines the enrollment behavior of persons 25 or older. We use data from a large-scale 1998 Department of Labor (DOL) policy demonstration in Greater Baltimore. By studying the behavior of older people we can examine factors such as age, earnings and marital status that vary little among the much-studied traditional students. Our results conform to the (rarely tested) predictions of human capital theory that age and opportunity costs are impediments to enrollment. We also find that where you live has a substantial impact on whether you return to school.  相似文献

Expansions of trinucleotide repeats at the level of genomic DNA are increasingly recognized as a cause of a number of neuropsychiatric disorders. Triplet repeat disorders are commonly classified into two groups, those with moderate CAG expansions that result in a polyglutamine stretch in the gene products and those with very long expansions, usually non-CAG, that are not translated. The triplet repeat intergeneration and intra-generational instability, and genetic anticipation characterize disorders. Most of the diseases caused by expanded CAG repeat share common features, which include neurodegeneration, a dominant pattern of inheritance and widespread expression of the gene products with neuronal loss restricted to distinct subset of neurons. Neurodegenerative changes associated of CAG expansion disorders is explained in terms of intra and extra cellular aggregation of mutant gene products, the insoluble nature of the protein(s) being attributed to the presence of polyglutamine stretches, hence their neurotoxic effects. methods based on poymerase chain reaction have become handy in the diagnosis of these genetic disorders. Progress in transgenic animal models for these disorders will be critical for understanding the progress of these disorders and for testing new therapeutic strategies.  相似文献

Rates of agreement among alternative definitions of reading disability and their 1- and 2-year stabilities were examined using a new measure of agreement, the affected-status agreement statistic. Participants were 288,114 first through third grade students. Reading measures were Dynamic Indicators of Basic Early Literacy Skills Oral Reading Fluency and Nonsense Word Fluency, and six levels of severity of poor reading were examined (25th, 20th, 15th, 10th, 5th, and 3rd percentile ranks). Four definitions were compared, including traditional unexpected low achievement and three response-to-intervention-based definitions: low achievement, low growth, and dual discrepancy. Rates of agreement were variable but only poor to moderate overall, with poorest agreement between unexpected low achievement and the other definitions. Longitudinal stability was poor, with poorest stability for the low growth definition. Implications for research and practice are discussed.  相似文献

There is a constant interplay between the “people” (agency) and the “parts” (structure and culture), not only in teaching and learning, but also in postgraduate supervision practices globally. However, in South Africa, the tendency to use structure (higher education architecture, institutional history, institutional rules, policies and procedures) to address all challenges related to postgraduate (especially doctoral) studies has resulted in university managers ignoring the role that institutional research culture (social norms, expectations and practice) plays, not only in perpetuating some of these challenges, but also in understanding and resolving them. At the University of Zululand (UniZulu), these factors combine to affect not only the postgraduate supervision practices of supervisors, but also the quality of doctoral throughput (doctorateness) with overall implications for society in general. This article is a critical self-reflection on the author’s postgraduate supervision practice at UniZulu between 2011 and 2016 with a view to highlight how structure and culture combine to impact on his supervision work at the institution. The discussion shows how these factors impact on the quality of doctoral output with implications for the author’s practice and society in general. To deal with the challenges arising from the discussion, the article recommends: establishing a dedicated postgraduate studies unit headed by a director or dean as supervisors and supervisees need a support system that functions optimally; improving staff qualifications and training of supervisors to keep up with best practice in postgraduate supervision; and the Department of Higher Education and Training factoring differentiation realities into its funding modules for universities.  相似文献

Researchers used alternating treatment designs to investigate the effects of listening‐while‐reading (LWR) and listening interventions on comprehension levels and rates in four middle school students with emotional disorders. During LWR, students were instructed to read passages silently along with experimenters. During the listening condition, we did not give students a printed copy of the passage but merely instructed them to listen as an experimenter read the passages aloud. The control condition consisted of students reading passages silently. After each condition, students answered 10 comprehension questions without referring back to the printed passage. Although neither intervention resulted in comprehension levels consistently superior to those of the silent reading control condition, LWR and listening resulted in higher rates of comprehension than the silent reading control condition across all four students. However, listening appeared to improve reading comprehension rates in only two students. These results suggest that LWR may be an efficient procedure for enhancing comprehension across content areas with groups of students who have heterogeneous reading skills. The discussion focuses on future applied research with students with disabilities. © 2005 Wiley Periodicals, Inc. Psychol Schs 42: 39–51, 2005.  相似文献

This paper examines the impact of the World Trade Organization’s (WTO) General Agreement on Trade in Services (GATS) on transnational higher education in four countries: New Zealand, Australia, Singapore and Malaysia. The GATS is a multilateral agreement through which WTO members commit to voluntary liberalisation of trade in services, including education. Transnational (or offshore) education refers to education that is delivered by an institution based in one country to students located in a different country. Two of the countries considered, New Zealand and Australia, have made commitments under GATS to allow relatively unrestricted cross-border provision of education in their countries, while the other two countries, Singapore and Malaysia, have made no such commitment. There is currently considerable activity in renegotiating countries’ commitments to GATS as part of the Doha round of WTO negotiations, and simultaneously bilateral free trade agreements are being proposed between countries in the region. In this context, this paper examines the practical impact that GATS has had on these two countries that have made commitments regarding education, and the likely impact that similar commitments by Malaysia and Singapore would have on the tertiary education systems in those major importing countries.  相似文献

This study explored how elementary teachers leveraged and structured student-involved formative assessment to promote metacognition and self-regulation. Research has suggested a connection between formative assessment practices (e.g., self-assessment and peer-assessment) and metacognition. However, this connection has limited empirical support, especially within early elementary contexts (i.e. Grades K-4). In this study, 44 Ontario elementary teachers completed a survey reporting their teaching and assessment practices and beliefs about metacognition. Five participants were then purposefully selected for semi-structured interviews to describe their experiences developing students’ metacognition and self-regulatory capabilities through student-involved assessment processes. Data were inductively and thematically analysed. Participants emphasized the value of assessment as learning practices (e.g., self-assessment and reflective thinking) to develop students’ metacognition and discussed the need for ongoing student feedback regarding metacognitive strategies. However, despite purposefully implementing formative assessment to enhance metacognition and self-regulation, participants articulated the need for additional resources to support the cultural shift towards assessment for and as learning within their classrooms.  相似文献

This experiment examined the applicability of the generalized matching law to changes in divided-attention performance produced by variations in relative reinforcement rate. Pigeons were exposed to a delayed matching-to-sample procedure in which compound samples (color 1 line orientation) and element comparisons (two colors or two line orientations) were used. The relative rate of reinforcement for accurate matches on the two types of comparison trials was varied. Variations in relative accuracy with changes in relative reinforcement were well described by the generalized matching law. We suggest that the bias and sensitivity parameters of the generalized matching law may measure the contributions of sensory activation and stimulus pertinence, respectively, to divided-attention performance. Additional work using similar analyses might contribute to a more general quantitative account of how differential consequences contribute to decision processes involved in the allocation of attention.  相似文献

Poor spellers/readers and younger normal children of similar spelling and reading ability carried out phonemic segmentation and spelling tasks. The poor spellers were impaired relative to controls in their ability to detect the odd word out where the middle or final phoneme of the word differed from that of the other items in the list. For example, in the series ‘dot',‘cot',‘pot', 'bat', the word ‘bat’ differs from the other items in terms of its middle vowel. Spelling errors were classified as being ‘pre-phonetic',‘phonetic', or ‘transitional’ in character, according to Morris and Perney's (1984) developmental scheme.‘Transitional’ errors indicate a knowledge of English orthography, and are relatively easy for the reader to decode phonetically, for example, green ?>‘grene', whereas ‘phonetic’ errors indicate a level of phonetic awareness which is not matched by an ability to represent the word according to the conventions of English spelling, for example green ?>‘gren'. Poor spellers were found to make significantly fewer ‘transitional’ errors than controls, there being a non-significant tendency for them to make more ‘pre-phonetic’ and ‘phonetic’ errors. It was found that performance on the odd word out task correlated significantly with the occurrence of ‘transitional’ errors, there being no such relationship with ‘phonetic’ errors.  相似文献
