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

The purpose of this study was to assess receptivity to peer teaching and peer learning about the safe and appropriate use of medications among communitydwelling older adults. The sample was predominately White (88.5%), female (75.9%) older adults with an average age of 80.2 ( - 9.1) years. On average, the participants perceived their health status as good (2.8 - 0.6). In addition, participants reported using an average number of 4.4 ( - 3.3) prescribed medications. The majority (75%) of participants also reported no problems with their medications. With respect to receptivity to peer teaching and peer learning, the participants, on average, were neutral to peer teaching (6.0 - 2.4), but were somewhat receptive to peer learning (6.7 - 2.2). The number of prescribed medications that a participant reported taking and the age of a participant were identified as significant predictors of receptivity to peer teaching and accounted for 14.5% of the total variance ( F = 5.84, df = 2, p = 0.005). For receptivity to peer learning, the number of prescribed medications also was a significant predictor ( F = 7.50, df = 1, p = 0.008). This study provides the initial step to identifying community-dwelling older adults who would be receptive to peer teaching and peer learning about the safe and appropriate use of medications. 相似文献

All universities in Australia are asked to develop various attributes in their degrees. From 2011, the Australian Qualifications Framework has stipulated some of these attributes for the various levels of qualifications. There are many challenges that face assuring the development of graduate attributes in a Bachelor of Arts as the degree typically has very few core units (if any), a wide choice of subjects, a limited prerequisite structure and, unlike many professional degrees, the BA does not have an external accrediting body. This paper describes an approach used to identify the pathway undertaken by each individual student in a History major of the Bachelor of Arts. This pathway was used to identify the graduate attributes that each student should have developed, as articulated by the lecturers. Student perceptions were then compared with the graduate attributes that were intended to be developed through each individual's combination of units studied. In summary, through analysing the two methods (student perceptions and unit pathway) we found that they concurred with respect to only three-quarters of the graduate attributes. Possible reasons for the discrepancies and future research are discussed. The need for multiple methods of providing evidence of the development of graduate attributes is confirmed. 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
