Abstract

Minority-serving institutions are important in the production of teachers of color. However, this formative process is not without limitations. This multisite, multistate study relied on network analysis techniques to unveil timely and relevant concerns that students, faculty, and administrators identified as critical toward the strengthening of teacher production.  相似文献

“The Bicycle Assembly Line Game” is a team‐based, in‐class activity that helps students develop a basic understanding of continuously operating processes. Each team of 7–10 students selects one of seven prefigured bicycle assembly lines to operate. The lines are run in real‐time, and the team that operates the line that yields the highest revenue wins. Students learn through discovery “What drives output rate?”; “How is capacity managed relative to market demand?”; and “Why does inventory accumulate?” Because task times are constant, the game provides a nice lead‐in to the topic of line balancing. This game has been successfully used in both undergraduate‐ and MBA‐level operations management courses.  相似文献

The goal was to test a new dual identity perspective on gender identity by asking children (n = 467) in three grades (Mage = 5.7, 7.6, 9.5) to consider the relation of the self to both boys and girls. This change shifted the conceptualization of gender identity from one to two dimensions, provided insights into the meaning and measurement of gender identity, and allowed for revisiting ideas about the roles of gender identity in adjustment. Using a graphical measure to allow assessment of identity in young children and cluster analyses to determine types of identity, it was found that individual and developmental differences in how similar children feel to both genders, and these variations matter for many important personal and social outcomes.  相似文献

The genetic and environmental etiologies of diverse aspects of language ability and disability, including articulation, phonology, grammar, vocabulary, and verbal memory, were investigated in a U.K. sample of 787 pairs of 4.5-year-old same-sex and opposite-sex twins. Moderate genetic influence was found for all aspects of language in the normal range. A similar pattern was found at the low end of the distribution with the exception of two receptive measures. Environmental influence was mainly due to nonshared factors, unique to the individual, with little influence from shared environment for most measures. Genetic and environmental influences on language ability and disability are quantitatively and qualitatively similar for males and females.  相似文献

In a previous simulation study of methods for assessing differential item functioning (DIF) in computer-adaptive tests (Zwick, Thayer, & Wingersky, 1993, 1994), modified versions of the Mantel-Haenszel and standardization methods were found to perform well. In that study, data were generated using the 3-parameter logistic (3PL) model and this same model was assumed in obtaining item parameter estimates. In the current study, the 3PL data were used but the Rasch model was assumed in obtaining the item parameter estimates, which determined the information table used for item selection. Although the obtained DIF statistics were highly correlated with the generating DIF values, they tended to be smaller in magnitude than in the 3PL analysis, resulting in a lower probability of DIF detection. This reduced sensitivity appeared to be related to a degradation in the accuracy of matching. Expected true scores from the Rasch-based computer-adaptive test tended to be biased downward, particularly for lower-ability examinees  相似文献
