One skill that student teachers need to develop during their academic studies is the capacity to produce accurate and well-organized texts. This study reports on the comparative impact of metalinguistic feedback (MLF), teacher interactive feedback (TIF(, and the peer-feedback (PF) on the accuracy and organization of postgraduate ELT student teachers’ writing. The participants were 57 postgradua...

background: the accuracy of pedicle screw placement is essential for lumbar and thoracolumbar spine fracture fixation. purpose: the aim of the present study was to assess the accuracy of the pedicle screw placement with conventional c-arm fuoroscopy-guided in these patients. methods: a retrospective review identified patients who underwent operative management with thoracolumbar instruments at ...

one important issue that any material or test designer should bear in mind is to be careful about developing teaching and testing reading materials which would not be to the benefit of a group of readers or examinees and to the detriment of some others. one of the factors which may cause difference between the performances of english learners or test takers is the selection of reading tests wit...

We have seen that the accuracy of methods for computing integrals or derivatives of a function f(x) depends on the spacing between points at which f is evaluated, and that the approximation tends to the exact value as this spacing tends to 0. Suppose that a uniform spacing h is used. We denote by F (h) the approximation computed using the spacing h, from which it follows that the exact value is...

Abstract— There are several works dedicated to the investigation of Volterra integro-differential equations. In addition, there are theoretical and practical representations of stable methods that have a high order of accuracy and extended stability regions; these representations were constructed using the minimum values of arithmetic operations. Here, hybrid methods are proposed for the constr...
