Consensus is Unfair     

Ruma Falk  Avital Lann 《Teaching Statistics》2006,28(3):81-83

A coefficient of unfairness in the allocation of goods to people can be extended to measuring consensus among judges. The notion of relative variability underlies the formation of these measures.  相似文献   

THINK: A Game of Choice and Chance     

Ruma Falk  Maayan Tadmor-Troyanski 《Teaching Statistics》1999,21(1):24-27

A game of chance in which players can maximise their expected gain by making appropriate decisions is described. Developing an optimal strategy involves computing probabilities and conditional expected values.  相似文献   

School Field Trips: Assessing Their Long-Term Impact     

John H. Falk  Lynn D. Dierking 《Curator: The Museum Journal》1997,40(3):211-218

Museums invest considerable resources in promoting and supporting elementary-school field trips, but remain skeptical about their educational value. Recent cognitive psychology and neuroscience research require a reappraisal of how and what to assess relative to school-field-trip learning. One hundred and twenty-eight subjects were interviewed about their recollections of school field trips taken during the early years of their school education: 34 fourth-grade students, 48 eighth-grade students, and 46 adults composed the group. Overall, 96% of all subjects could recall a school field trip. The vast majority recalled when they went, with whom they went, where they went, and three or more specific aspects of what they did. Most said that they had thought about their field-trip experience subsequently, nearly three-quarters said they thought about it frequently. Reinforced by this study were the strong interrelationships between cognition, affect, the physical context and social context. Even after many years, nearly 100% of the individuals interviewed could recall one or more things learned on the trip, the majority of which related to content/subject matter.  相似文献

Impact of early clinical experiences on student attitudes about diversity     

Randi B. Wolfe  Francine C. Falk‐Ross 《Journal of Early Childhood Teacher Education》2013,34(2):157-165

Abstract

Undergraduate pre‐service teachers enrolled in the first professional semester of an early childhood teacher preparation program were assigned clinical placements in schools with diverse student populations. Pretest and posttest self‐report questionnaires and focus group discussions were used to gain insight into the impact of the experience. Quantitative and qualitative analysis of the feedback indicate that early clinical placements in diverse settings can positively impact student attitudes toward children of religious and cultural groups different from their own. Such experiences can also impact student views of priorities in teacher education. Implications for teacher preparation programs are offered.  相似文献   

Children’s concept of probability as inferred from their binary choices—revisited     

Ruma Falk  Patricia Yudilevich-Assouline  Adily Elstein 《Educational Studies in Mathematics》2012,81(2):207-233

Children had to choose one of two urns—each comprising beads of winning and losing colours—from which to draw a winning bead. Three experiments, aimed at diagnosing rules of choice and designed without confounding possible rules with each other, were conducted. The level of arithmetic difficulty of the trials was controlled so as not to distort the effects of the constituent variables of proportion. Children aged 4 to 11 first chose by more winning elements and proceeded with age to choices by greater proportion of winning elements. There were some indications of intermediate choices by fewer losing elements and by greater difference between the two colours. Distinguishing correct choices from favourable draws, namely acknowledging the role of chance in producing the outcome and insisting on the right choice, grew with age. Children switched rather early from considering one dimension to two; they combined the quantities of winning and losing elements either additively by difference or, with age, mostly multiplicatively by proportion. Guided playful activities for young children, based on this research, are suggested for fostering acquisition of the basic constituents of the probability concept: uncertainty of outcome, quantification by proportion, and the reverse relation between the chances of complementary events.  相似文献   

Weighted Means Through the Looking Glass     

Ruma Falk  Avital Lavie Lann 《Teaching Statistics》2013,35(2):103-106

Each weighted mean of two values has a counterpart, equidistant from the arithmetic mean, obtained by exchanging roles between the weights or by inversing each weight. These elementary relations are apt for introductory courses.  相似文献   

Talent identification and early development of elite water-polo players: a 2-year follow-up study     

Bareket Falk  Ronnie Lidor  Yael Lander  Benny Lang 《Journal of sports sciences》2013,31(4):347-355

The processes of talent detection and early development are critical in any sport programme. However, not much is known about the appropriate strategies to be implemented during these processes, and little scientific inquiry has been conducted in this area. The aim of this study was to identify variables of swimming, ball handling and physical ability, as well as game intelligence, which could assist in the selection process of young water-polo players. Twenty-four players aged 14–15 years underwent a battery of tests three times during a 2-year period, before selection to the junior national team. The tests included: freestyle swim for 50, 100, 200 and 400?m, 100-m breast-stroke, 100-m ‘butterfly’ (with breast-stroke leg motion), 50-m dribbling, throwing at the goal, throw for distance in the water, vertical ‘jump’ from the water, and evaluation of game intelligence by two coaches. A comparison of those players eventually selected to the team and those not selected demonstrated that, 2 years before selection, selected players were already superior on most of the swim tasks (with the exception of breast-stroke and 50-m freestyle), as well as dribbling and game intelligence. This superiority was maintained throughout the 2 years. Two-way tabulation revealed that, based on baseline scores, the prediction for 67% of the players was in agreement with the final selection to the junior national team. We recommend that fewer swim events be used in the process of selecting young water-polo players, and that greater emphasis should be placed on evaluation of game intelligence.  相似文献
