In computer-supported collaborative learning, technology is used for enabling constructive approaches to learning as well as group interaction, particularly in distant and asynchronous situations. Recently, shared workspace systems have been developed that allow for jointly constructing conceptual problem representations by means of graphical structures and direct manipulation as well as the in...
In a recent paper (Girard 2012), Girard proposes to use his recent construction of a geometry of interaction in the hyperfinite factor (Girard 2011) in an innovative way to characterize complexity classes. We begin by giving a detailed explanation of both the choices and the motivations of Girard’s definitions. We then provide a complete proof that the complexity class co-NL can be characterize...
The group Z acts on the real line R by translation. It is difficult to find a nontrivial group action which is easier to understand: the orbit of every point moves off to infinity at a steady and predictable rate, and the group action preserves the usual Euclidean metric on R. Of course, this action is a covering space action, and the quotient space of the action is the circle, which is complet...
abstract the present study tried to investigate the effect of visual aids (films) on the development of the speech act of disagreement among iranian efl intermediate learners. to this end, the researcher selected 40 homogeneous intermediate learners based on their scores on oxford placement test. .the subjects then divided into control group and experimental group. both classes were tested by ...
Class action is a legal procedure of a considerable group of people to take joint actions against a single defendant. In this form of action, one or more people representing while also being a member of a class, take an action for themselves and on behalf of others, regarding a common claim among the members of the class. Although the members of the class have no active role in the ju...
this study investigated the effect of prior knowledge on the listening comprehension performance of fl learners. twenty students, male and female, drawn from the two intact groups of the senior and junior english language and literature majors were chosen as the participants of this study . the two groups were then randomly assigned into the experimental and control group. the experimental gr...
فرض کنید g یک گروه متناهی باشد به طوری که مربع هر درجه کاراکتر تحویل ناپذیر آن اندیس مرکز گروه را عاد می کند. آیا می توان نتیجه گرفت که گروه پوچتوان یا حتی حلپذیر است؟ همچنین در مورد بعضی از تعمیمهای فوقالذکر بحث خواهیم کرد. همچنین، تا چه اندازه ساختار یک گروه حلپذیر توسط بزرگترین درجه کاراکتر تحویل ناپذیر گروه تحت تاثیر قرار میگیرد مورد بحث قرار خواهد گرفت. let g be a finite group such tha...
