objectives: in present study, we studied the effect of teaching three painting methods (free method, subject selection method and complementary method) on creativity of children with learning disabilities. first, among all disabled students, who refer to bizhani center for learning disabilities in arak city, 60 subjects were randomly selected as statistical sample. thus, the 45 children, divide...

M-learning (i.e. mobile learning) is a field of elearning that provides learners learning environments using mobile technology. In this context, learning can take place anywhere and anytime, in open and distance learning. Depending on the type of technology it may be done through software called nomadic (i.e. prepared to mobility). Among these technologies, there are those composed of digital i...

so far various methods for optimization presented and one of most popular of them are optimization algorithms based on swarm intelligence and also one of most successful of them is particle swarm optimization (pso). prior some efforts by applying fuzzy logic for improving defects of pso such as trapping in local optimums and early convergence has been done. moreover to overcome the problem of i...

Computerized dynamic assessment has been proposed as a solution to the practicality issues involved in ordinary dynamic assessment procedures. However, most of computerized dynamic assessment studies have addressed receptive skills (i.e., reading and listening). Responding to the scarcity of CDA studies of productive skills, the present study was an attempt to design and implement a computerize...

The present study was conducted to investigate the impact of using computer-aided argument mapping (CAAM) on the improvement of Iranian learners’ writing self-regulation. To this end, 90 participants out of 127 senior university students in English translation were selected after administrating language proficiency test, as well as an essay writing test for the purpose of homogenizing the learn...

this paper deals with ridge estimation of fuzzy nonparametric regression models using triangular fuzzy numbers. this estimation method is obtained by implementing ridge regression learning algorithm in the la- grangian dual space. the distance measure for fuzzy numbers that suggested by diamond is used and the local linear smoothing technique with the cross- validation procedure for selecting t...
