A comparison of sentence-learning errors in children of different achievement levels     

Joel R. Levin  Elizabeth S. Ghatala  Bruce G. Bender 《Contemporary educational psychology》1978,3(4):358-366

Theoretical analyses of the multiple-choice test format suggest that a test constructor should give serious consideration to the form in which correct and incorrect alternatives are presented. In this experiment, third and fourth graders were tested for previously exposed information by multiple-choice items in which: (a) correct alternatives were stated in either verbatim or synonym form; and (b) incorrect alternatives consisted of plausible responses that were either familiar or new. Comparisons of errors and error patterns were made between high and low achieving students who had been given one of two different information-processing strategies. Based on a dual test function argument, it was concluded that synonym correct alternatives combined with plausible new responses are the most desirable of the four multiple-choice variations studied here. In particular, such items were sensitive to achievement level and strategy differences without systematically increasing students' likelihood of retaining misinformation.  相似文献   

Precise asymptotics in the law of the logarithm for random fields in Hilbert space     

FU Ke-ang  ZHANG Li-xin 《浙江大学学报(A卷英文版)》2007,8(4):651-659

Consider the positive d-dimensional lattice d (d≥2) with partial ordering ≤, let {XK; K ∈ d } be i.i.d. random vari- ables taking values in a real separable Hilbert space (H, ||·||) with mean zero and covariance operator ∑, and set partial sums SN =∑K≤NXK, K , N ∈ d . Under some moment conditions, we obtain the precise asymptotics of a kind of weighted infinite series for partial sums SN as ε 0 by using the truncation and approximation methods. The results are related to the convergence rates of the law of the logarithm in Hilbert space, and they also extend the results of (Gut and Spǎtaru, 2003).  相似文献

The attainment of doctoral degrees at Flemish Universities: a survival analysis     

M. S. Visser  M. Luwel  H. F. Moed 《Higher Education》2007,54(5):741-757

This paper examines the propensity to attain a Ph.D. degree at the five largest universities in Flanders, the Dutch speaking part of Belgium. It provides insight into the rate at which junior scholars appointed at the universities involved attained their Ph.D.-degree, and the duration of the doctoral training period. Cox’s regression model was applied to statistically analyse the influence of a number of ‘demographic’ and ‘merit’ variables, and variables related to funding source and type of appointment of the junior scholarly staff. Large differences in Ph.D. durations and attainment rates were found across funding sources, research disciplines and types of appointments. The policy background and implications are discussed briefly.  相似文献
