        Increment of complexity and costs of information technology systems have made many problems about infrastructure and manpower for organizations which have been decreased by the use of outsourcing. All organizations try to increase the success of outsourcing projects by using different ways. One of the important reasons for failure of these projects especially in IT area- because of its major role in acquisition of competitive advantage- is selecting inappropriate contractor. In order to existence of different and contradictive criteria, this selection is complex. The purpose of this research is to determine important criteria and specify the weights of each criterion and finally design a fuzzy expert system for selecting the best contractor in IT outsourcing. The method of knowledge acquisition from experts-which are managers and experts of IT- is a questionnaire. Also in order to evaluate the validity of system, it was used in an IT company. The results show the favorable performance of contractor selection expert system. Manuscript profile

        Educational multimedia has changed the traditional methods of education. But their impact requires careful design based on the objectives of the lesson and the abilities of their users. In the current research, the effect of educational multimedia on learning and memorizing the grammatical structure (grammar) of the English language has been studied. For this purpose, a researcher-made software was designed for teaching grammar and it was studied in the experimental group and its results were compared with regular classes. The statistical population was first grade female middle school students in Tehran city, which was randomly selected by multi-stage cluster sampling method, first in district 8, and then in a sample school, two groups of first grade middle school students, one group as The experimental group and one group were selected as the control group, each consisting of 55 students. This research is a quasi-experimental method and descriptive and inferential statistics have been used to analyze the data. The control group underwent traditional language training in the classroom, and at the same time, the experimental group experienced three grammar training sessions on the school's computer site using the software developed by the researcher. The results of the research showed an increase in learning and memorization of grammatical structure at the level of 0.05 in the group using educational multimedia in comparison with the control group, which finally confirms the effect of multimedia on learning and memorizing English grammar.
