The impact and significance of a training process may not be easily noticeable in the short term, and is difficult to track in the long term. This is more common when training targets are acquiring positive attitudes and competences (i.e. environmental awareness) rather than specific technical procedures. Thus, such training requires specific evaluation tools for quantifying the degree of achievement the objectives. Microteaching is a training methodology characterized by brevity and flexibility, which focuses in promoting active learning and evaluating its long-term impact (including performance indicators). The methodology was developed during two European projects (Leonardo da Vinci Programme(Overschie,2006; Pérez-Moya, 2008, www.microtrainingsupport. eu/).
