Efectos sobre el aprendizaje informal de la evolución biológica como resultado de la mediación museal.

Interactive science museums have been considered spaces where informal learning can occur especially when the communication between exhibits and visitors is facilitated. A research is presented here, in which the effects on knowledge, problem solving and attitudes towards science in mediated visits to an exhibition about biological evolution (which tends to be a communicative difficult theme) are evaluated. The results show that there is no significant gaining between the two first aspects in the case of guided visits, but instead, the presence of museum guides helps to solve questions and promotes the desire to visit again. So, the guides are an invaluable support to explore visitor's previous information and to reduce the dislike for a particular topic. Besides, it enhances the attention on the main subject of the exhibition and helps to fulfill the expectances of the visit. All this promotes the desire to have a longer visit, which can increase the time spent in the museum. These findings will have to be taken into account in the guide's preparation.
