Table-top Role Playing Games (RPGs) can be a powerful educational tool, but many teachers either aren't aware of that, or don't know how the game works. This problem could be alleviated with an authoring tool that facilitates the process of creating educational table-top RPG adventures and, at the same time, provide an introduction and computer-based support to this game genre. Literature on available authoring tools oriented to the creation of games in educational contexts is still scarce. Therefore, this article presents our efforts towards the design of a web authoring tool that aims at helping both teachers and students in the creation of educational table-top RPG adventures and also in the posterior use of these adventures in the classroom. The goal behind this work is to promote this genre of games and computers in education. 600610Berlanga, A.J., García, F.J., Authoring tools for adaptive learning designs in computer-based education (2005) Proceedings of the 2005 Latin American Conference on Human-computer Interaction - CLIHC'05, pp. 190-201. , Cuernavaca, Mexico: ACM Press. doi:10.1145/1111360.1111380Bottino, R.M., Robotti, E., Transforming classroom teaching & learning through technology: Analysis of a case study (2007) Educational Technology & Society, 10 (4), pp. 174-186Carbonaro, M., Cutumisu, M., Duff, H., Gillis, S., Onuczko, C., Siegel, J., Schaeffer, J., Interactive story authoring: A viable form of creative expression for the classroom (2008) Computers & Education, 51 (2), pp. 687-707. , doi:10.1016/j.compedu.2007.07.007Hergenrader, T., Gaming, world building, and narrative: Using role-playing games to teach fiction writing (2011) Proceedings of the 7th International Conference on Games + Learning + Society Conference (GLS'11), pp. 103-108. , http://dl.acm.org/citation.cfm?id=2206389, C.
