Virtual Mineralogical Museums and Mineral Websites as Learning Agents: Analysis of How Minerals Are Represented

Virtual mineralogical museums can help visitors construct and enhance their personal scientific mineral models through the information they incorporate. For this to be possible, they must contain a series of key aspects related to minerals’ properties (chemical and physical), use and origin, and the relationships between them. In this study, 38 sites are analyzed, their main characteristics identified, and their educational value assessed, to verify whether all the key aspects considered for the construction of an appropriate and complete mineral model are present. Photographs and mineral files predominate over 3D models and 3D tours. In many of the sites aimed at university students or geoscience experts, there are abundant data about mineral properties, but not in those aimed at a broad public audience. Data about the uses and relationship between uses, extraction, and mineral properties are seldom included. Even if connectivity is very high in all the sites, there are no elements that can be used to test if there has been a knowledge gain after visiting them. The results show that there is still a lot of information missing for this type of resources to be truly helpful for the general population and, specifically, for educational uses.
