teachers’ beliefs greatly influence their performance in the classroom, their choice of instructional strategies, their way of controlling the class, their dealing with the students, and their general goals and objectives. one of these beliefs is teachers’ sense of efficacy which is viewed as an important construct and has shown to be positively correlated with students’ achievement (ross, 1992...
the subjects of the study are only the tefl teachers and students at gilan university. to obtain the desired data, a questionnaire which was based on the theories and disecussions gathered, was used as the main data gathering instrument. to determine the degree of relationship between variables, covariance and pearson product moment correlation coefficient were the formulas applied. the data we...
It is shown that the Stirling numbers of the first kind can be expressed in the form [n k ] = ∑n−1 j1<j2<···<jk−1 (n−1)! αQ[j1,j2,...,jk−1] , where Q is a product of k − 1 linear factors in the indices j1, j2, . . . , jk−1 and α is a normalization coefficient determined by the condition [ k k ] = 1. Several types of Q’s are shown to yield Stirling numbers (“be Stirling”), and some more are conj...
Using the saddle point method, we obtain from the generating function of the Stirling numbers of the first kind [ n j ] and Cauchy’s integral formula, asymptotic results in central and non-central regions. In the central region, we revisit the celebrated Goncharov theorem with more precision. In the region j = n− n, α > 1/2, we analyze the dependence of [ n j ] on α.
In this short note, we present a simple constructive proof for the generating function for the unsigned Stirling numbers of the first kind using the equidistribution of pilots and cycles of permutations.
abstract this study examines the effect of teaching lexical inferencing strategies on developing reading comprehension skill of iranian advanced efl learners. participants were female students of meraj and shokouh institudes of garmsar a quasi-experimental design using two intact advanced classes of efl students at meraj and shokouh institutes. as the first step, a general toefl proficiency te...
A remarkable multiple analogue of the Stirling numbers of the first and second kind was recently constructed by the author. Certain summation identities, and related properties of this family of multiple special numbers are investigated in the present paper.
In this paper, we consider generalizations of the Stirling number first and second kind by using a specialization new family symmetric functions. We give combinatorial interpretations for these functions means weighted lattice path tilings. also present some convolutions involving complete elementary Additionally, introduce different families set partitions to modular s-Stirling numbers.
