This paper seeks to focus on the creation of discourses on human communication in family. To do it, the contemporary approaches of sociology and process of their formation are used. Attention to the dimensions of time and space to explain the discourse creation is the most important aspect of integrated approaches of sociology (or relational approach): an analysis far beyond the causal analysis: Considering both micro- and macro-levels): Moving towards generalization and using the chaos theory to explain the repeated forms are characteristics of this analysis. A grounded theory is used in this research. Analysis of the data collected from the families of the 22 districts of Tehran is conducted through quantitative data analysis (factor analysis) and for classification of items and formation of the theoretical ones, grounded theory was used.The process of producing the discourse of human communication in family includes the followings steps: the flow of discourse principle, Withdrawal of abstraction (speaking on the writing), creating the Compelling regulations (speaking on reading) and creating the intermediate structures (speaking on the exchange). These steps are based on the theory of knowledge, the SECI model and Foucault's methodological approach. During the first phase, the principle of discourse flow, family events creates innovation and changes the tacit knowledge to the shared explicit communication. The second step, leaving the abstraction, family members changes the tacit knowledge to the shared explicit knowledge through using the words, signs, symptoms and talking with other people. The third stage, beyond systematization and offering the explicit knowledge and simplification of the more complicated concepts needed in family communication, it changes the explicit knowledge to implied one. In the fourth stage, binding mediation structures internalizes the implicit knowledge and this process continues. In this paper, we tried to focus on the discourse of family communication.
