JPSY_V9_N1_RP2 Ilana Ronen Journal on Educational Psychology 2230 – 7141 9 1 13 24 Discourse Community; Emergent Knowledge; Semiotic Evolution; Complex System A qualitative research focused on a case study aiming to monitor emergent knowledge in a discourse group by tracking the development of the concept 'goal'. The analysis, based on 'Semiotic Evolution' methodology facilitates the description of interactions between personal perceptions in the group discourse, illustrating the change process and signs development. It is suggested that knowledge was emerged from a free, self-organized discourse interaction which was encouraged by a constructivist leadership. The new knowledge was manifested by expanding the boundaries of the concept 'goal' and it changed the members' behavior. Understanding emergent knowledge is useful in teaching and Teacher Education processes as well as in Adult Education. May - July 2015 Copyright © 2015 i-manager publications.
