This paper analyzes the negotiation of meaning at boundary crossings. Many studies have shown how the concept of boundary crossings is used in an interdisciplinary sense. In this paper， I focus on boundary crossings based on activity theory and communities of practice. In the existing literature， the negotiation of meaning is mainly placed in a homogeneity context. However， this paper offers a perspective on the importance of the negotiation of meaning at boundary crossings in a heterogeneity context. The review of the literature reveals that brokers in external communities of practice can introduce external practices into internal communities of practice through the reconciliation of decentralized selves. For brokers， the experience of crossing boundaries promotes the cognition and conflict of decentralized selves. The mechanism of reconciliation of decentralized selves for brokers can be explained with dialogical self theory with polyphony. Furthermore， the reconciliation of decentralized selves promotes brokers to deliver the negotiation of meaning at boundary crossings in a heterogeneity context.
