The study aims to investigate the role of social networks in facilitating academic exchanges among faculty members at Ilam University.

The present study is applied in nature and was conducted using a survey method. The statistical population for this study consists of faculty members at Ilam University. The sample size was determined using the Cochran formula, resulting in a total of 127 participants. The Mirzaei Questionnaire (2016) was utilized to collect data. To determine the sample size within the categories, a stratified random sampling method was employed. To evaluate the validity of the questionnaire, experts in the relevant field frequently conducted assessments. The reliability of the questionnaire was measured using Cronbach's alpha coefficient, which was found to be 0.925, indicating high reliability. SPSS software was utilized for data analysis. To test the hypotheses, both the one-sample t-test and the Friedman test were employed.

The findings indicated that all faculty members utilize social networks. Notably, 48% of professors spend more than three hours a day on these platforms. Among the social networks referenced in the ResearchGate questionnaire, it was the most frequently used. The laptop is the most important tool for accessing social networks. The majority of respondents use both Persian and English. Based on the results obtained, the use of social networks can effectively enhance the knowledge of professors. According to the results, the most significant advantage of using social networks, as expressed by professors, was the ability to foster motivation for conducting research activities. Conversely, professors identified privacy concerns as the primary obstacle to utilizing social networks. The average score for the knowledge improvement component among faculty members is 4.09, which is significantly higher than the overall average of 3. Therefore, with 95% confidence, we can conclude that the effectiveness of using social networks to promote knowledge among faculty members is above average. The items associated with the knowledge promotion component have been ranked using the Friedman test. A comparison of the average ranks indicates that the significance and ranking of the mentioned components differ from one another with 95% confidence (P<0.05).

The use of social networks is common among professors and the use of these networks can be effective in improving their knowledge. Considering the importance and role of social networks in establishing scientific exchanges between researchers, it is necessary to introduce these networks correctly. To help improve and effective productivity of these networks. The component of the influence of social networks in scientific exchanges showed that the use of social networks in scientific exchanges among faculty members of Ilam University is higher than average.

Gender of the authors: 53% of them were men and 47% of them were women. According to the findings of the research, the most participants in writing articles are assistant professors (158), Associate Professor 119, doctorate student (114), master's student (100), doctorate (47), professor (42), unreported (20), student Bachelor's degree (12), postdoctoral degree (1).Researchers in the field of information science and Knowledge have contributed the most in writing articles with 75%. Researchers in the field of business management (12%), educational sciences (2%), and information technology (01%) contributed more than other fields in writing articles in the journal. The most participation was by the authors of Kharazmi University; Also, Isfahan University with 27 article titles, Azad University with 25 article titles, Tehran University with 21 article titles, Beheshti University with 18 article titles, and Chamran University with 15 article titles Unreported 14 article titles, Al-Zahra University 10 article titles, Allameh Tabatabai University 10 article titles, Ferdowsi University of Mashhad 10 article titles, Tabriz University 9 article titles, Tarbiat Modares 8 article titles, Shiraz University 7 article titles, Shahid University 5 article titles, Mohaghegh Ardabili University 5 article titles  respectively have contributed the most in writing articles. The population of quantitative researches was students, professors, and academics. In terms of the research approach, among the 242 published articles, 123 articles were conducted with a quantitative approach, which includes 51% of the research, and qualitative research accounted for 28%, and mixed research for 21%.

applied researches with 185 numbers have the highest percentage of 77% of the human and information interaction quarterly, and developmental and fundamental researches are in the next ranks with 32% and 25%, respectively. Also, the most applied researches, 10 titles, belong to the fourth issue of the five-year period of 2018, and the most basic researches, 5 titles, were published in the fourth issue of 2021. Research method strategy: According to the findings of the research, descriptive research with 167 titles is the highest percentage (69 percent),  and correlation research 35% in the second rank and experimental research with 30 titles with 13% frequency in the rank are next. In the following, comparative and historical causal researches with 5 article titles are at the End. The level of research analysis: The findings of the research show that the level of analysis of 78% of the articles published in the quarterly is the group level, and the individual, intersection, and organizational levels account for a total of 21% of the researches. The review of the articles shows that 64% of the researches conducted in the Scientific Quarterly of Human and Information Interaction have used primary data to conduct the research. Data collection method Most researches have used questionnaires (74%) to collect data. The interview method is ranked next with (24%).

The analysis of the distribution of the gender frequency of the authors of the articles showed the difference in the role-creation of men compared to women in writing articles. In such a way that men have had a greater contribution and role in writing articles. The frequency distribution of the organizational affiliation of the authors of the articles showed that the most participation was by the authors of Kharazmi University. This indicates the fact that the researchers of Kharazmi University are more inclined to send their researches and achievements to their university journal, and naturally, this tendency increases the acceptance rate and the high percentage of participation of the researchers of this university in publishing articles. Considering that the field of organization has received less attention from researchers, besides the need to investigate the reasons for the low interest of researchers in this field in an independent research it is suggested that the editorial board and judges determine research priorities in the subject areas.Due to the limitation of the research method used in 69% of the articles, it seems that the variety of research methods in the acceptance and publication of the journal articles should be given more attention by the reviewers, editor-in-chief, and other officials. In some informational articles, such as Society and statistical sample, the exact title of the university, organization, orientation, author's field, etc. are not mentioned, so it is suggested that the editorial board and the internal manager pay more attention. The data collection tool is a set of questionnaires and other tools are used less. Therefore, it is suggested that the editorial board and judges pay more attention to the acceptance of articles that use other tools to collect data. It is obvious that using various tools helps to increase the scientific richness of researches. Due to the unequal participation of researchers from different scientific fields in publishing articles in the quarterly journal, publishing articles in different fields with an almost equal ratio in each issue of the journal can solve this imbalance and equality. Also, the determination of research needs by the journal can lead researchers to other fields. About 77 percent of the reviewed researches were of applied type and exploratory researches had a smaller contribution; Therefore, it is suggested that the acceptance of exploratory researches should also be prioritized; Because this type of research helps to expand existing knowledge in line with research goals.

To present and explain the method of narrative analysis: the most important (definitions, applications, objectives, strengths and weaknesses, characteristics, methods, validity and reliability) Collection.

Reviewing and studying documents and information sources from Persian and English books and papers.

Activity narration is very important since narratives help people turn their experiences into meaningful scenes of a story. This requires the use of cultural reasoning methods and content presentation. Narrative is a basic design for linking human events that creates an understandable combination. Narrative research has been considered from two perspectives: the research design or the output of a research. The research design was used to collect and analyze people's narratives of their experiences during life, and the output of the research refers to the expression of research research that is presented to the audience in a story-like manner. One of the most important differences between ethnography and narrative research is that the purpose of ethnography is to study and understand its culture and meaning based on different participants (behavior, value, way of thinking, etc.). While in narrative research, its purpose is to know individual experiences and their meaning. Narrative data such as different types of stories are collected in a variety of ways, including semi-structured interviews computer contexts, written conversations, ethnographic methods, and applied contexts such as therapy.Life Narrative Studies provide a compelling way to test hypotheses because they reveal rich psychological dynamics in human life.

Narrative Narrative analysis as a qualitative methodology for advancing social research has been increasingly used by researchers in social sciences and other fields.

This research was carried out with the aim of analyzing the main elements and implementation challenges of the think-aloud protocol.

This research is a qualitative type of research that was done with the library method. The statistical population of this research is all the scientific articles related to the think-aloud protocol that are indexed in the databases. The research tool is also a checklist.

The two basic things that are required in loud protocol research are training and reminder. Also, among the challenges in this method are the real management of thinking aloud protocol, increasing the duration of the method compared to other methods, the possibility of distorting the reports provided by the participant, the need to interpret the processes before learning more than The limit occurred, retelling whatever came to mind even if it was irrelevant, noted the reactivity and realism of the think-aloud protocols.

By using good performance practices in the aloud thinking process, people who use aloud thinking protocols have better strategies for solving current problems and can also gain more content knowledge while doing so. This method may be very helpful in special training and intervention, such as teaching math problem-solving skills or teaching a second language, considering how to support participants.
