We defined learning while searching and browsing on the Web as ”learning by searching.” We used concept map to evaluate how users’ knowledge structure changed as a result of their learning by searching. The influence of different topics and different scenarios was also investigated. In the experiment, participants were divided into divergent and convergent scenario groups. They were asked to as...

The influence of diet and fluoride on odontogenesis in rats was investigated. 20 foetuses, 20 days old, were divided into four groups. The control group was fed with the standard diet and drank water with 0.16 mg F/l. The second, third and fourth groups were fed with the deficit, experimental diet and drank distilled water with 10 and 110 mg of natrium fluoride per litre or without fluoride. In...

Interactive tabletops can be used to provide new ways to support face-to-face collaborative learning. A little explored and somewhat hidden potential of these devices is that they can be used to enhance teachers’ awareness of students’ progress by exploiting captured traces of interaction. These data can make key aspects of collaboration visible and can highlight possible problems. In this pape...

This study was an attempt to investigate the comparative impact of concept map and mind map instruc- tion on EFL learners’ descriptive and narrative writing. To fulfill this purpose, 60 intermediate EFL learners were selected from among a total number of 100 through their performance on a pretest, i.e., a piloted sample Cambridge Preliminary English Test (PET). T...

the concept of the bipartite divisor graph for integer subsets has been considered in [‎graph combinator., ‎ 26 (2010) 95--105‎.]. ‎in this paper‎, ‎we will consider this graph for the set of character degrees of a finite group $g$ and obtain some properties of this graph‎. ‎we show that if $g$ is a solvable group‎, ‎then the number of connected components of this graph is at most $2$ and if $g...
