Popis: Introduction In the process of PBL implementation, faculty members often ask what are the criteria for constructing problems and subsequently evaluating them. Although experts agree on a fundamental theoretical basis for developing problems, mostly prototypical, it is difficult to find specific criteria that could be used in constructing PBL problems. Method A Delphi technique using six independent judges from the Rouen School of Medicine, France, answered this question. It took four rounds and five months. Results Nine criteria were identified and rank-ordered according to their relative importance: 1 – stimulating thinking, analysis, and reasoning (openness 6·8 points); 2 – assuring self-directed learning (autonomy 6·5); 3 – using previous basic knowledge (richness 6·2); 4 – proposing a realistic context (attractiveness 5·7); 5 – leading to the discovery of learning objectives (coverage 5·0); 6 –arousing curiosity (inquisitiveness 5·0); 7 – choosing topics related to public health (relevance 5·0); 8 – assuring contextual breadth (comprehensiveness 4·8); and 9 – choosing an appropriate vocabulary (medical encoding 4·7). Discussion The identification represents a fresh outlook on the PBL process, from judges who had recent experience in constructing PBL problems. Related to Barrow’s dimensions, these criteria could be seen as a more concrete and specific level of conceptualization. Paired with those found in the literature, they match six out nine already identified, although not prioritized criteria. Conclusion Judges from a school just having implemented PBL, found that Reasoning and Autonomy are the most important criteria for constructing PBL problems.
