We examined associations between the explicit mathematics-related gender stereotypes of students, parents, teachers, and classmates and students’ motivational-affective outcomes in mathematics (self-concept, interest, anxiety) at the end of Grade 9. Based on representative data from the German Trends in Student Achievement 2018 study (N = 30,019), results of latent multilevel mixture models show that boys’ and girls’ explicit beliefs in the stereotype favoring their own gender in-group (i.e., boys’/girls’ belief that boys/girls do better at mathematics) were related to higher levels of self-concept and interest and to lower anxiety. Parents’ gender stereotypes showed an incremental association with all three outcomes for girls but only with mathematics self-concept for boys. Gender stereotypes of teachers were not related to students’ outcomes. However, classmates’ stereotypes favoring girls or boys in mathematics were negatively associated with outcomes of the positively stereotyped group. Thus, a male student in a classroom with classmates who share the traditional stereotype that boys do better at mathematics than girls would hold a lower self-concept and interest and higher anxiety level after controlling for the beneficial individual association of himself having the same belief and his motivational and affective outcomes. Similarly, a girl’s motivational-affective outcomes would be more favorable in the same environment characterized by the shared traditional stereotype of mathematics as a male domain after controlling for the negative individual association. Shared stereotypes in the classroom could thus trigger social comparison processes to which students are more susceptible than to stereotypes of their teachers.  相似文献

This paper investigates the use of e-books as learning tools in terms of learner satisfaction, usefulness, behavioral intention, and learning effectiveness. Based on the activity theory approach, this research develops a research model to understand learner attitudes toward e-books in two physical sizes: 10″ and 7″. Results suggest that screen size could affect learners' perceived self-efficacy in using 10″ and 7″ e-books. Interactive learning environments, acceptable screen size, perceived self-regulation, and self-efficacy could positively influence perceived satisfaction with and usefulness of e-books as learning tools. Perceived satisfaction and usefulness are crucial factors in learner behavioral intention which, in turn, contributes to learning effectiveness. The paper also proposes a conceptual research model based on the activity theory approach.  相似文献

目的:从溶质和溶剂粒子之间的作用力和溶液的凝聚态解释稀溶液依数性。方法:根据拉乌尔定律提出后100多年来发现的实验事实,分析溶质和溶剂粒子的受力情况和凝聚态。结果:提出了“溶剂束缚球”假说,成功地解释了稀溶液依数性产生的原因,指出了拉乌尔定律错误的根源。结论:溶剂束缚球和分子平均缔合度是产生稀溶液依数性的原因。  相似文献

ABSTRACT

This article relates changes in higher education (HE) and research in East Asian societies to recent trends in political economy and, in particular, the reorientation of developmental states (DSs) in the region. The DS is oriented to catch-up competitiveness and, as the horizon of development shifts, so do its appropriate institutional forms and strategies. Catch-up competitiveness is guided by economic imaginaries, often linked to geoeconomic, geopolitical, and broader societal imaginaries, whose hegemony depends on particular discursive and disciplinary practices. The shift in the roles of HE and research is related to the reorientation of DSs from export-oriented, investment-led growth to knowledge-intensive, investment-led growth, supplemented in some cases by efforts to create international financial hubs to exploit a global trend towards financialisation. These themes are explored through comparison of selected East Asian economies/societies. The article ends with some general conclusions about the state's continuing role in HE and its internationalisation in the region.  相似文献

测量一点的主应力的电测实验是材料力学实验中的基本实验。在该实验中,为了测量构件表面一点的主应力大小及方向,通常采用3个1/4桥路,测量该点沿3个敏感栅方向的线应变,根据平面应变状态分析和广义胡克定律求得该点的主应力大小及方向。该文通过对构件表面一种常见应力状态的分析,提出了只用1个1/4桥路和1个1/2桥路便可测得该点主应力大小及方向的简便方法,从而简化了实验过程,提高了测量精度。  相似文献
