Many real world situations (potluck dinners, academic departments, sports teams, corporate divisions, committees, seminar classes, etc.) involve actors adjusting their contributions in order to achieve a mutually satisfactory group goal, a win-win result. However, the majority of human group research has involved situations where groups perform poorly because task constraints promote either ind...

Group dynamic assessment (G-DA) grounded in Vygotsky’s socio-cultural theory (SCT) is believed to have the potential to provide a context for capturing a group of learners’ Zone of Proximal Development (ZPD) (Poehner & Lantolf, 2010; Shabani, 2010). The present study aims at testing the applicability of G-DA in identifying the mediational strategies offered by a mediator during his G-DA interac...

researchers have suggested that interactional feedback which is between teacher and learner during their writing is associated with l2 learning because it prompts learners to notice l2 forms. this paper reports a classroom-based study that investigated the role of feedback in socio-cultural theory. in this study, 12 efl learners performed on three writing tasks and were provided with a three-st...

Individual differences studies are those that investigate the interaction between a subject level covariate, such as sex, age, or performance, and the effect of an experimental task. Commonly, a brain region is selected on the basis of the task effect, and the signal in this region correlated with individual covariates. It is shown here that, provided that data are identically and independently...

In this work, the concept of mutually unbiased frames is introduced as most general notion unbiasedness for sets composed by linearly independent and normalized vectors. It encompasses already existing notions orthonormal bases, regular simplices, equiangular tight frames, positive operator valued measure, also includes symmetric informationally complete quantum measurements. After introducing ...

this study is an attempt tofind the effect of four types of feedback(direct,underline,code,translation)on the writing performance of iranian learners ofjapanese as a foreign language.in this research,we have tried to suggest new ways of correcting students’writing through giving different kinds of feedback in the process of learning to write.the study focused on the accuracy of using prepositio...

corrective feedback (cf) and its different types have long absorbed many scholars and practitioners. as ellis (2009) mentioned some experimental studies need to be carefully designed to discover the relative effectiveness of each of these cf techniques. the goal of this qualitative study was to discover whether the employment of different cf strategies could bring about an attitudinal shift. to...
