The following study investigates the range of strategies individuals develop to infer and interpret cross-sections of three-dimensional objects. We focus on the identification of mental representations and problem-solving processes made by 11 individuals with the goal of building training applications that integrate the strategies developed by the participants in our study. Our results suggest that although spatial transformation and perspective-taking techniques are useful for visualizing cross-section problems, these visual processes are augmented by analytical thinking. Further, our study shows that participants employ general analytic strategies for extended periods which evolve through practice into a set of progressively more expert strategies. Theoretical implications are discussed and five main findings are recommended for integration into the design of education software that facilitates visual learning and comprehension. 相似文献

Nurturing Careers in Psychology: Combining Work and Family 总被引：3，自引：3，他引：0

The academic workplace, with its requirements for achieving tenure within the first 6 years of employment, is designed in
ways that discriminate against young faculty with family care responsibilities, most notably mothers. Mason and Goulden (Academe, http://www.aaup.org/publications/Academe/2002/02nd/02ndmas.htm, 2002, Academe, http://www.aaup.org/publications/Academe/2004/04nd/04ndmaso.htm, 2004) found that women faculty who have babies within the
first 5 years following the receipt of their doctorate are less likely to earn tenure than women without babies or men in
general. Women at research-intensive universities are twice as likely as their male colleagues to report that they had fewer
children than they wanted. In addition, only one-third of women who begin their academic career at research-intensive institutions
without children will become a mother. These inequities, sometimes called the “baby gap” or “motherhood penalty” make academic
institutions difficult places for new faculty with family care responsibilities. Suggestions are provided to assist new faculty
in successfully combining their work and family roles (e.g., establish gender equity in parenting and negotiate for family-friendly
policies) and to senior faculty and administrators who want to nurture the careers of their younger colleagues (e.g., support
the use of family-friendly policies on campus). 相似文献

The transition movement of the 1980s was preceded by two similar movements: (a) the career education movement in the 1970s and (b) the work/study movement in the 1960s. These three movements are described and compared to provide an historical context for understanding current problems and issues regarding transition. Some broad social issues, such as educational reform, are then examined to illustrate the potential influence of such issues on the future developments of policy that will affect the transition movement. 相似文献

The present study tests the assumption that peers wield sufficient influence to induce sexual homophily (i.e., similarities in sexual experiences). Because girls face greater stigma for their sexual experiences than do boys, sexual homophily may be greater in girls' friendship networks than in boys'. Stochastic actor-based models were used to analyze network data (n = 2,566; ages 14–18) from two high schools in the National Longitudinal Study of Adolescent to Adult Health. Sexual homophily was present in friendship networks. Girls and boys were equally susceptible to their friends' influence, but the former exhibited a stronger preference for befriending same sexual debut status peers than the latter. The findings suggest that adolescents—particularly girls—“curate” their networks to minimize peer ostracism. 相似文献
