Assigned to three groups of DCF, ME, and control groups, the participants took four tests in three testing phases: pretest, posttest, and delayed posttes...

In this paper, we introduce a novel technique to improve surface mesh quality while maintaining all essential surface characteristics. In contrast to previous methods we do not constrain node movement to the underlying discrete surface. Instead our approach allows keeping resultant mesh very close to the surface approximated by the original mesh. Proposed method is explicit, that is we do not n...

Interaction faults caused by a flawed external system designed by a third party are a major issue faced by interconnected systems. In this paper, we define a scenario where this type of problem occurs, and describe some fault cases observed in real systems. We also discuss the most important challenges faced in this scenario, focusing on error detection. The problem is divided in several sub-pr...

The present study attempts to uncover language teachers’ beliefs about oral corrective feedback. It also explores the role of teachers’ experiences in their choice of error correction techniques. To achieve the purpose of the study, 137 foreign language teachers were asked to fill out the developed questionnaire and follow-up interviewed were conducted with 10 teachers, five novice and experien...
