This article analyzes a reflexive process lived along a trajectory of development of Physics games, created by a teacher (MCF), in high school distinct realities. Two phases were identified: the first was represented by her search to make physics teaching enjoyable; the second, under Paul Black theoretical perspective, was brought to reality in response to a question about which elements of formative assessment could be taken into account during games development. The analyses also revealed that interpersonal and theoretical influences lived by the teacher were determining for her to recognize herself as a "reflexive teacher", at the end of the trajectory.
