The purpose of this descriptive study was to explore inservice teachers' definitions of project-based learning (PjBL) and their accounts on the meaning of their PjBL implementations. A purposive sample of six teachers from grades four through twelve in public and private schools participated. Three themes evolved from inductive analysis: (1) teachers define PjBL through its perceived advantages on learning, (2) teachers vary in their use of PjBL over the continuum of the learning process, and (3) teachers adopt student-centered approaches in PjBL. Interpretations and implications of the findings are also presented.
