This paper aims to explore the discrepancy between self-reported and test-based literacy estimates in Bangladesh. It uses the Education Watch national literacy survey data of 2002, during which the literacy status of a nationally representative sample was identified using the two methods referred to above. The findings revealed that the literacy rate generated through a literacy test was significantly lower than that found when the self-report method was used. The level of discrepancy varied from one population group to another, indicating that literacy assessment using the self-report method cannot be equally appropriate for all population groups. Those with a few years of schooling were at a particular risk of over-estimating their status. The paper makes a case for a written literacy assessment rather than an oral evaluation.  相似文献

There are child soldiers fighting with government forces and opposition groups in more than 30 countries worldwide. Although studies have been conducted on the impact of war-related trauma on children, very few have focused on those children who do not exhibit trauma-related symptoms after experiencing armed combat. The purpose of this study was to identify and understand some of the mechanisms and resources that resilient children draw upon to overcome the trauma of child soldiering. Six Colombian child soldiers were recruited through purposive sampling techniques to participate in a narrative study focusing on their lived experiences and their personal understanding of how they were able to overcome the effects of war trauma. Six narrative themes were identified and discussed in terms of the literature on trauma and childhood resilience and also related to counselling needs and services.  相似文献

Gill, P. E. 1976. The Relationship Between Mental Ability and Eight Background Variables. Scand. J. educ. Res. 20, 135‐145. Multiple regression is seen as a search technique when applied to IQ. test data. The results from such a search are stochastic rather than deterministic. Because of this it is imperative that comprehensive samples be studied. The sample in this study (n = 3,695) was representative of the population of Irish 6‐ to 12‐year‐olds. The results are surprising in that the total variance explained by predictors such as SES, sex, family size, position in family, absenteeism and urbanity is never more than 8 %. Differences in how predictors behave with IQ and Vocabulary are noted. SES, family size and urbanity are the most significant predictors. When Vocabulary is the criterion, sex differences (in favour of girls) emerge consistently. It is contended that pupils of low intelligence go absent more often than their peers. The total variance explained was increased when homoscedasticity was reduced by stabilizing criterion variance (by reducing age span).  相似文献

The hypothesis of acting White has been heatedly debated and influential over the last 20 years or so in explaining the Black–White test score gap. Recently, economists have joined the debate and started providing new theoretical and empirical analyses of the phenomenon. This paper critically reviews the arguments that have been advanced to support and refute the hypothesis. This review particularly covers the analyses in economics because the economic analyses are relatively new and usually neglected in other disciplines. Also, nationally representative data are emphasized, whenever possible, to improve the generalizability of the arguments. This review concludes that although the analyses in both non-economics and economics are thought-provoking and compelling in some respect, a substantial body of empirical evidence is inconsistent with the assumptions of and results from the analyses.  相似文献

Given the paucity of studies conducted to know the effect of suddenness and earlier onset of endocrinological changes associated with hysterectomy, on the serum and urinary levels of calcium, magnesium and phosphate the present study was conducted to compare the levels of calcium, magnesium and phosphate in serum and urine of hysterectomised and natural menopausal south Indian women. This is a cross-sectional observational study. The study included three groups of 30 healthy premenopausal, 30 early surgical menopausal and 30 natural post menopausal women. Women suffering from any endocrine disease were excluded. Analysis was performed in serum and urine sample. The levels of calcium, magnesium and phosphate in serum and calcium/creatinine, magnesium/creatinine and phosphate/creatinine ratio were estimated in urine by spectrophotometric method. Hysterectomised women (serum calcium: 8.7 ± 0.09 mg/dl; urine calcium/creatinine: 0.16 ± 0.02) have significantly low serum calcium (p < 0.001) and high urinary calcium/creatinine (p = 0.002) ratio and post menopausal women (serum magnesium: 2.1 ± 0.03; serum phosphate: 4.4 ± 0.16; urinary calcium/creatinine: 0.17 ± 0.02; urinary magnesium/creatinine: 0.09 ± 0.01) have significantly high serum magnesium (p = 0.016), serum phosphate (p = 0.043) and high urinary calcium/creatinine (p = 0.002), magnesium/creatinine ratio (p = 0.025) compared to healthy pre menopausal women. Post menopausal women (serum calcium: 9.1 ± 0.08) have significantly high serum calcium and phosphate compared to hysterectomised women (serum phosphate: 3.93 ± 0.11). Hysterectomised women have significantly low serum calcium, oestrogen and high urinary calcium/creatinine ratio compared to healthy premenopausal women and low serum calcium and low serum phosphate compared to natural postmenopausal women. Natural postmenopausal women had low serum oestrogen and high serum magnesium, serum phosphate, urinary calcium creatinine ratio and urinary magnesium creatinine ratio compared to healthy premenopausal women.  相似文献

This conceptual paper tackles the matter of teaching in higher education and proposes a concept of ‘horizons of teaching’. It firstly offers an overview of the considerable empirical literature around teaching—especially conceptions of teaching, approaches to teaching and teaching practices—and goes on to pose some philosophical and social theoretical considerations that open further the territory around teaching in university. Against this background, we propose the concept of ‘horizons of teaching’. Horizons of teaching provide a context in which it makes sense for teachers to give themselves to the teaching enterprise and to go on giving themselves to teaching. Horizons include diverse and intricate layers at both micro- and macro-levels that interact in a permanent and dynamic way; they involve persons and collectivities; and they concern structures and agency. The paper concludes by proposing that horizons of teaching configure and delineate curricula and the pedagogical relationship in a way that might contain a revolutionary potentiality in recasting teaching in higher education.  相似文献

In two experiments, participants inspected and drank a series of drinks, half of which contained sugar and half unpalatable Tween20 (tween). Each sugar and tween drink had a particular flavor and color. Following this training, the flavors of the sugar drinks were assigned higher hedonic evaluations than were those of the tween drinks, even though the participants did not reliably report which flavors had been present in the sugar and tween drinks during training. Moreover, the evaluative conditioning of the flavors was unaffected by whether or not the colors alone had been pretrained to predict the presence of sugar or tween in the drinks. In accord with Baeyens, Eelen, van den Bergh, and Crombez (1990), we conclude that flavor-evaluative conditioning is not mediated by contingency learning.  相似文献

The purpose of this study was to describe and understand the range of outcomes of class visits to natural history museums. The theoretical framework is based on the multifaceted process of learning in free choice learning environments, and emphasizes the unique and individual learning experience in museum settings. The study’s significance is in highlighting several possible cognitive as well as non-cognitive learning effects in museums class visits, by providing the student’s point of view. Data was collected by semi-structured interviews with 50 students in grades 6–8 on the day following the visit. We present evidence that students expressed several learning outcomes, connected directly and indirectly to the scientific content of the visit. Content oriented outcomes included acquiring scientific knowledge and making connections to prior knowledge; social oriented outcomes were identified in students’ statements regarding communicating knowledge and social aspects of learning; and interest oriented outcomes were evidenced by students’ expressions about emotions, interest and curiosity. The aggregate data addressed the common outcomes and the impact of class visits to natural history museums in the short term. Comparisons between two types of museums show significant differences in several aspects, regarding the exhibit and/or the activity type. Practical ideas for structuring the ultimate experience are included.  相似文献
