The paper aims to highlight the problem of the space of teaching the subject of plastic arts in Tunisian schools and its engineering structure. In addition, it intends to identify differences between technical practices at the applied stage based on several variables related to the Learning workshop and to explore possible answers to the whole range of questions associated with research. Besides it tries to discover the different teaching and learning methodology based on the study space variable and the study share laboratory space which provided research comparison through the observation and corresponding mechanism during field visits and defined the features of the space dedicated to the exercise of a formative activity. The results of the research revealed the inadequacy of applied technical practice in the plastic arts when associated with the school’s traditional space and classroom for success and creative take-off when changing the features of the learning space to match the laboratory’s specifications. The research underscored the importance of changing the school’s engineering and technical specialty hall to become a predominant, capable of accommodating experimental exploratory curriculum stages in plastic activity from observation and mediation to experimentation and retraining.
