Meaningful group times have been a hallmark of quality early childhood programs for many years. Stimulating group experiences present a wealth of opportunities for everyone involved. Adults are better able to monitor children's skills and enjoy their ongoing growth. Group activities also may set the stage for an abundance of adventures as young children grow and learn in all areas of their development (Bredekamp, 1986).Pauline Davey Zeece and Marcia Corr are at the Department of Human Development and the Family, University of Nebraska-Lincoln in Lincoln, Nebraska. 相似文献

In seven experiments, 2 squirrel monkeys were given choices between arrays of food that varied in the quantity offered. In Experiments 1-5, the monkeys were offered choices between quantities of the same food that varied in a 2:1 ratio. The squirrel monkeys failed to show the temporal myopia effect or a decrease in preference for the larger quantity as the absolute number of food items offered increased. Even when given choices of 8 versus 16 peanuts and 10 versus 20 peanuts, both monkeys significantly preferred the larger quantity. An examination of the monkeys' rates of consumption indicated that 20 peanuts were consumed over a 1- to 2-h period, with eating bouts separated by periods of nonconsumption. In Experiments 6A, 6B, and 7, food was either pilfered or replenished 15 min after an initial choice, so that choice of the smaller quantity led to more total food in the long run. These manipulations caused both monkeys to reduce choice of the larger quantity, relative to baseline choice. The results suggest that squirrel monkeys anticipated the future consequences of their choices. 相似文献

This article explores ways in which children's picture books form networks of relationships, and their implications for readers and classroom teachers. In this exploration, reading is seen to involve making connections within and beyond the text at hand. These connections, evoked differently across readers, shape readers' interpretations of text. Many possible meanings may arise from just one text, reinforcing the idea that no single correct meaning resides in a text. This article demonstrates tools for exploring textual connections with readers, and the value of such explorations for opening‐up reader interpretations of a text. 相似文献

This study considers a frailty duration approach to modelling the life-length of a sample of 360 films that went into wide
release at the Australian box office from 1 January 2000 to 31 December 2005. The analysis extends previous research by
considering a range of film-specific covariates relating to distribution, production, consumer signals, and weekly performance.
In particular, it is shown that film success (defined in a duration context) responds to previewing, advertising, critical
reviews, and US box office—but not to production budget, star power or opening-week screens. The study also reveals that it
is appropriate to account for unobservable heterogeneity between films in the choice of empirical methodology. 相似文献

There is little research on students' engagement in physical activity in middle school physical education (PE). We observed student activity, lesson context, and teacher behavior in 430 PE lessons taught by 126 teachers in 24 schools. Variables were analyzed by mixed-model nested analyses of covariance. Boys were more active than girls overall and during skill drills, game play, and free play. Student activity varied by lesson context, with fitness activities producing the most activity. Class size was negatively associated with student activity. Daily PE contributed a weekly total of 25 min of vigorous activity and 83 min of moderate-to-vigorous activity--much less than national objectives. Results suggest that numerous opportunities exist for increasing student physical activity during middle school PE. 相似文献
