Studies with adults suggest that implicit preferences favoring White versus Black individuals can be reduced through exposure to positive Black exemplars. However, it remains unclear whether developmental differences exist in the capacity for these biases to be changed. This study included 369 children and examined whether their implicit racial bias would be reduced following exposure to positive Black exemplars. Results showed that children's implicit pro‐White bias was reduced following exposure to positive Black exemplars, but only for older children (Mage = ~10 years). Younger children's (Mage = ~7 years) implicit bias was not affected by this intervention. These results suggest developmental differences in the malleability of implicit racial biases and point to possible age differences in intervention effectiveness. 相似文献

The aim of this article is to analyse whether having experience of formative assessment during their initial teacher education courses (ITE) influences graduates’ subsequent practice as teachers. That is, if the assessment methods that university students are subject to during their learning process are then actually employed by them during their professional practice as schoolteachers. To address this issue, questionnaires were issued and focus groups were held with a sample of ITE graduates. The main results of the study are that: (1) formative and shared assessment (FSA) is not used a great deal during ITE, but is highly valued; (2) some graduates have implemented FSA in their practice as teachers, following their experience on their ITE course; and (3) significant variables are found regarding the implementation of FSA in schools (possible resistance from colleagues and/or pupils’ parents, etc.). 相似文献

The aim of this research has been to test the efficacy of an intervention programme on lexical-semantic problems in children with Specific Language Impairment (SLI). The sample consisted of 34 children diagnosed with SLI and 34 children with typical language development, all enrolled in different schools on the island of Tenerife (Canary Islands, Spain). For the selection of the sample, CELF-3, Peabody, ITPA Auditory Association and Visual Association subtests and the K-BIT IQ tests were used. The intervention programme consisted of 72 sessions of 30 minutes each, using noun and action naming activities along with conversation and categorization tasks in order to increase vocabulary and improve lexical semantic competence. Significant results were achieved in aspects related to the acquisition of vocabulary as well as in lexical semantics or related terms. The educational implications are clear insofar as lexical-semantic aspects are key in terms of activating other linguistic components and in improving the academic progress of SLI students. 相似文献

In the present paper, we develop a teaching methodology for economic theory. The main contribution of this paper relies on combining the interactive characteristics of spreadsheet programs such as Excel and Unicode plain-text linear format for mathematical expressions. The advantage of Unicode standard rests on its ease for writing and reading mathematical expressions. In this sense, our proposal allows incorporating an easily readable and writable methodology to cope with math expressions when interactive spreadsheets are used and designed in Economics teaching. The resulting nearly plain text can be used with few or no modifications in other numerical computing programs. 相似文献

Stretching the academic harness: knowledge construction in the process of academic mobility in Chile
In this article, we analyse the impact of academic mobility on the construction of knowledge for Chilean scholars who have studied abroad. We conducted 41 semi-structured interviews with Chilean-born scholars in the social sciences and humanities, who accepted jobs at national research universities in Chile after receiving their doctorates abroad. Findings show that international academic mobility allowed these participants to question legitimised ways of doing knowledge, where they can stretch the academic harness that increasingly rules their knowledge construction. Our main argument is that knowledge construction process is neither linear nor unidimensional and it occurs as a rhizomatic process in a multidimensional space. 相似文献

Through the analysis of survey and interview data, we investigated the attitudes and perceptions of 32 multilingual teachers of Spanish in Belize, a code-switching (CS) context where Spanish is in intense contact with English and Belizean Kriol. More specifically, we examined teachers’ and students’ attitudes toward Spanish and CS and teachers’ perceptions vis-à-vis students’ attitudes toward Spanish instruction. The study revealed that whereas some teachers held negative views of Northern Belizean Spanish, they did not markedly perceive standard Spanish as “better” than the local variety of Belizean Spanish. The analysis also showed that most teachers had a positive predisposition to the use of CS as a pedagogical tool in their classrooms, a finding that suggests that ultra-normative attitudes toward Spanish varieties are not prevalent among these educators. In view of students’ attitudes, teachers concurred that students had overwhelmingly negative attitudes toward standard Spanish, in line with previous findings. We argue that educational reforms and status-planning efforts are vital to destigmatize Spanish and to promote its maintenance alongside Belizean Kriol and English. 相似文献

This work is devoted to the study of symmetric control systems. It establishes a relation between internal symmetry and external one for a linear invariant control system having n real simple poles. The symmetric stabilization problem is studied using a symmetric feedback gain such that the output control stabilizes the closed-loop system. A necessary and sufficient condition is given to solve this stabilization problem for a symmetric control system (A,B,C) and a generalized symmetric control system (E,A,B,C). 相似文献

The aim of the present study was to conduct an analysis of TIMSS (Trends in International Mathematics and Science Study) 2003 database and to determine how negative school factors, such as aggression, are associated to the mathematical and science achievement of students. The analyses were conducted separately for national and international data. National analyses for Slovenia show significant associations between math and science achievement and the experience of aggressive behaviour. Students who experienced aggressive behaviour scored lower in math and science, both in the fourth and in the eighth grade. The results of the regression analysis show that negative factors, such as aggressive behaviour, are good predictors of educational achievement in Slovenia. International analyses for the selected countries (high‐ and low‐achieving countries from the whole TIMSS population) confirm that this type of finding is culturally impartial as well as valid for the level of achievement both in math and in science. 相似文献
