This qualitative study investigates the process of learning verbs, as one of the fundamental aspects of learning Persian language, by PSL (Persian as a second language) Learnersthrough dynamic assessment and using new technologies which are in contradiction with the traditional approaches of teaching and assessment. In so doing, two Iraqi students of Razi University were subjected to a four-month enrichment program that captured their microgenetic development and involved using IMO which, as a realization of new technologies, provides its users with the opportunity of synchronized electronic communication. Results indicate that each learner upon receiving the right level of instruction and prompts moved along the continuum of mediation internalization to get closer to the self-regulation extreme which in turn denotes their social and cognitive development in their Zone of Proximal Development in using the target structures. That is, dynamic assessment via electronic communication equipped the researchers with an in-depth knowledge of each learner`s position along the continuum of other-self regulation which was followed by the appropriate level of instruction and led to his development. The findings of this study contribute to the area of second language teaching in general and Persian language teaching in particular.

The purpose of the present study was to produce a web-based curriculum model. This study was an applied descriptive-analytic survey. The statistical population of the study consisted of 524 individual teachers and 58 pedagogical experts from Lahijan، Iran in 2014، among whom 308 teachers and 58 pedagogical experts were selected as the sample size. The researcher-made questionnaire including 72 items on web-based curriculum was used as the data gathering tool. The validity of the questionnaire was estimated by the Kaiser-Meyer-Olkin (KMO) measure of sample adequacy and Bartlett test of sphericity which proved an adequacy for conducting the factorial analysis and reliability of the questionnaire was estimated by Cronbach Coefficient (α=0. 946). To analyze the data، the descriptive statistics and inferential statistics with factorial analysis test were used. The factor analysis was conducted based on the analysis of the main components، and the results revealed that the web-based curriculum model comprised of 6 main components which could be modeled. The main components، totally، explained the 51. 280% of the variables total variance. Finally، simple structure of factors was obtained by using the oblimin rotation of factorial matrix. The factors were termed as ''objectives and needs''، ''content and sources''، ''learning-teaching methods''، ''implication'' and ''evaluation''. Finally، based on these factors، a conceptual model for web-based educational programs was designed.

The goal of this study was to investigate the influence of fundamentals of modern educational technology training on students’ life skills in universities of Mazandaran Province. Considering the objective، it was a practical research، and considering the method، it was a semi-experimental procedure with pretest/posttest and control group. The statistical population included all university students in academic year of 2012-2013 (n=312586). Using cluster random sampling method، three colleges were selected، and using stratified random sampling method with optimum ratio allocation، a number of 50 individuals were selected as sample and placed in the test and control groups. Data collection tool was a researcher made questionnaire that contained 45 questions and four skill dimensions (decision making، problem solving، critical thinking and creative thinking). The face and content validity were approved by faculty advisors and reliability was calculated 0. 86 using Cronbach''s alpha coefficient. Data analysis was performed using covariance analysis test and t test. Findings showed that the fundamentals of modern educational technology (web-based training، computer and mobile learning) had a significant effect on life skills (decision making، problem solving، critical thinking and creative thinking). Also، there was no significant difference between modern educational technology impacts on students'' life skills based on their gender.

Collaborative learning tools play important roles in communications and knowledge building، among learners in a virtual learning environment. They demand appropriate grouping algorithms as well as facilitating learners’ participations mechanisms. This paper has utilized some information retrieval techniquesto investigate the relevance of discussion posts to their containing forums، and extract learners’ most frequent topics. Trying to explore students online interactions، researchers have applied social network analysis، which has led to a new representation of social networking. They have proposed a new grouping algorithm based on the provided representation of social relationships. The mentioned approaches have been evaluated in some academic courses in Department of Electrical and Computer Engineering، and ELearning Center، University of Tehran. The results have revealed some considerable improvements in comparison to the traditional approaches. Research outcomes may help tutors to create and guide groups of learners more effectively.
