Yu, Ji Hyun. Ph.D., Purdue University, December 2013. Development and Validation of Pre-service Teachers’ Personal Epistemologies of Teaching Scale (PT-PETS). Major Professor: Peggy Ertmer. The Internet has changed not only how we conceptualize knowledge, but also how we learn in classroom. Knowledge is not any longer transmitted from experts to nonexperts, but is constructed through communicat...

the present study investigated the potential of implementing reading strategy instruction in raising learner readers' awareness of reading strategies,  extending the range of strategies they employed and enhancing their reading comprehension ability. to conduct the study, 90 female pre-university students majoring in natural sciences were selected based on a convenient sampling procedure. after...

Collocations in the sense of idiosyncratic binary lexical co-occurrences are one of the biggest challenges for any language learner. Even advanced learners make collocation mistakes in that they literally translate collocation elements from their native tongue, create new words as collocation elements, choose a wrong subcategorization for one of the elements, etc. Therefore, automatic collocati...

We rigorously study a novel type of trigonometric Fourier collocation methods for solving multi-frequency oscillatory second-order ordinary differential equations (ODEs) q′′(t) + Mq(t) = f(q(t)) with a principal frequency matrix M ∈ Rd×d. If M is symmetric and positive semi-definite and f(q) = −∇U(q) for a smooth function U(q), then this is a multi-frequency oscillatory Hamiltonian system with ...

A collocation-Galerkin method is defined for Poisson's equation on the unit 2 square, using tensor products of continuous piecewise polynomials. Optimal L and Hq orders of convergence are established. This procedure requires fewer quadratures than the corresponding Galerkin procedure. Introduction. The collocation-Galerkin method was first introduced by Diaz [2], [3] for the two-point boundary ...

Abstract This paper describes an experiment that attempts to compare a range of existing collocation extraction techniques as well as the implementation of a new technique based on tests for lexical substitutability. After a description of the experiment details, the techniques are discussed with particular emphasis on any adaptations that are required in order to evaluate it in the way propose...

the present study attempted the relative effect of explicit teaching of textual metadiscourse markers on esap reading comprehension performance of iranian university students through an awareness raising experiment. a sixty-item multiple choice esap reading comprehension test of accounting was developed and validated to act as the pre-test and post-test. the test included items for assessing sp...

the purpose of this research was to determine the effect of volleyball skills training and problem solving on adolescent girls self-efficacy. the research method was semi-experimental and conducted in as pre-test and post-test with four experimental groups.the research statistical population consisted of all first grade students of broujen high schools in the academic year of 2009-2010(1388-89s...

Background Integration of web-based educational tools into medical training has been shown to increase accessibility of resources and optimize teaching. We developed a web-based educational portal (WBEP) to support teaching of pediatric residents about newborn medicine by neonatology fellows. Objectives 1) To compare residents' attitudes about their fellow-led education in the NICU pre- and pos...
