This paper is concerned with issues affecting equity in science education for girls and boys. In the paper the results of an investigation into the recently published (1998–2000) series of textbooks entitled Lower Secondary Science for Brunei Darussalam are presented. In the first part of the paper, background issues of continuing gender inequality in science education and of the nature and scope of textbook analyses are outlined. Then the representation of males and females in both illustrations and text in the Bruneian textbooks is discussed. From this analysis a picture emerges of the extent to which science is portrayed as a pursuit of equal appropriateness for both boys and girls. The paper concludes with a consideration of the implications of the findings presented within the wider context of gender and education in Brunei. 相似文献

An implicit assumption that fostering inclusion means having shared systems encompassing the needs of all children is evident in many aspects of policy development over the past decade. Reflecting this, the implementation of ‘baseline assessment’ schemes (i.e. testing at around age 5 years) is a statutory requirement on all state-maintained special and mainstream schools in England since 1998. Our argument is that the enthusiasm for commonality has obscured the need to question the value and validity of baseline assessment schemes for children with special educational needs (and possibly some others such as children having English as an additional language). We illustrate this position with reference to data from our recent study on baseline assessment in England. The study encompassed survey data from a national sample of 982 schools, of which 107 were special schools. Between them, these special schools used 42 different baseline assessment schemes. Comparisons between our mainstream and special school respondents indicated that there were similarities in the nature and perceived value of the schemes used. However, special schools were less satisfied with their schemes. We suggest that a reappraisal of the nature and purpose of baseline assessment for pupils with special educational needs warrants greater critical debate. Without this, there is a danger that a stress on commonality, veiling an inclusion orthodoxy, will ultimately be counterproductive. 相似文献

Through a qualitative interview design, this study investigated how participation in a rigorous academic environment may influence gifted students who demonstrate high levels of perfectionism. The study also examined how their responses to a rigorous academic and residential environment may differ according to the type of perfectionism. Findings indicated that some socially prescribed perfectionists reported an increase in perfectionism, whereas some self-oriented perfectionists reported an increase followed by a decrease in their perfectionism. Overall, the majority of the participants, regardless of their type of perfectionism, indicated a decrease in their perfectionism as a result of their new academic environment. Reactions to experiencing imperfections ranged from calm to guilt or even anger, depending on the type of perfectionism. Implications for working with gifted students who show high levels of perfectionism are discussed. 相似文献

To test the hypothesis that formal operational reasoning modes are predictors of critical thinking abilities and grades assigned by teachers in science and mathematics, in September 1986 the Group Assessment of Logical Thinking (GALT) and in December 1986 the Watson-Glaser Critical Thinking Appraisal (WGCTA) were administered to 101 rural students in Grades 9 through 12. The grades assigned by teachers were collected in May 1987. Construct and criterion-related validities and internal-consistency reliability using Cronbach's alpha method were established on the GALT. On the WGCTA, content and construct validities and internal consistency reliability using the split-half procedure, coefficient of stability, and coefficient of equivalence were established. The five formal operational reasoning modes in the GALT were found to be significant predictors of critical thinking abilities and grades assigned by teachers in science and mathematics. The variance in the five critical thinking abilities attributable to the five formal operational reasoning modes ranged between 28% and 70%. The five formal operational reasoning modes explained 29% of the variance in mathematics achievement and 62% of the variance in science achievement. 相似文献
