The value of written corrective feedback (CF) has been an issue of considerable debate in the literature (e.g. Truscott, 1996; Ferris, 1999), and this polemic has lead to a trend in recent studies to draw on second language acquisition (SLA) research as a way to further comprehend the intricacies of this complex issue. Indeed, Ellis, Sheen Murakami and Takashima (2008) delineate between focused...

Teacher-students’ and students-students’ interactions are of significant importance in foreign language teaching and learning. It is argued that interactions between teachers and students facilitate language development and lead to better language learning.

This paper investigates the effectiveness of concordance-based material for an EFL problem—misordering in expressions of measurement. A specifically designed preand posttest is developed for testing Thai students’ ability to use the expression. The sample comprises four groups of university students in their first and second years (two groups each). One first year group and one sophomore group ...

A method for solving the descriptor discrete-time linear system is focused. For easily, it is converted to a standard discrete-time linear system by the definition of a derivative state feedback. Then partial eigenvalue assignment is used for obtaining state feedback and solving the standard system. In partial eigenvalue assignment, just a part of the open loop spectrum of the standard linear s...
