Data mining is known to have a potential for predicting user performance. However, there are few studies that explore its potential for predicting student behavior in a procedural training environment. This paper presents a collective student model, which is built from past student logs. These logs are first grouped into clusters. Then, an extended automaton is created for each cluster based on the sequences of events found in the cluster logs. The main objective of this model is to predict the actions of new students for improving the tutoring feedback provided by an intelligent tutoring system. The proposed model has been validated using student logs collected in a 3D virtual laboratory for teaching biotechnology. As a result of this validation, we concluded that the model can provide reasonably good predictions and can support tutoring feedback that is better adapted to each student type.

Angélica JiménezThis article presents an investigation on the educational value of virtual worlds intended for the acquisition of procedural knowledge. This investigation takes as a case of study a virtual laboratory on biotechnology. A remarkable feature in this virtual laboratory is an automatic tutor that supervises student’s actions and provides tutoring feedback when it is appropriate. The study presented in this article covers two different aspects of the system. First, it analyzes the impact of this virtual world in learning some concepts related to a biotechnology practice; and second, it surveys the students’ opinion on the virtual world by means of three open questions (positive, negative, and general impressions). Results demonstrated that the virtual world had a positive influence in the students’ knowledge, and it was well received by them.

Angélica JiménezThis paper describes the preliminary results of an educational innovation project in which virtual world technologies have been used to build up a set of virtual laboratories oriented to engineering studies. Focusing on the architecture of a biotechnology laboratory created in this project, we describe how this architecture will also be adopted in other labs under construction, so that these labs can also take advantage of the same educational benefits. Instead of relying on a commercial software solution, these labs have been created with an open source software infrastructure named OpenSim. The limitations found in OpenSim and the solutions that have been provided to overcome these limitations are shown.

About Me
Currently a faculty member in the Department of Numerical Methods at the Colegio Universitario de Estudios Financieros (CUNEF). He holds a Ph.D. in Software and Systems (UPM, 2017), a Master’s in Software and Systems (UPM, 2012), and a Bachelor’s degree in Computer Systems Engineering (Escuela Politécnica Nacional, Ecuador, 2006).
From 2004 to 2010, he worked as a custom software development engineer in private companies in Ecuador. Since 2010, he has dedicated himself to teaching and research activities at academic institutions in Ecuador (USFQ and UISEK) and Spain (UPM), highlighting his role as Director of the Digital School at UISEK (Dean) between 2019 and 2023. A lifelong video game enthusiast, he has developed 3D training simulators and taught courses on programming and video game development within the Information Systems Engineering program with an emphasis on Interactive Content (video games) at UISEK.
His main research interests include virtual environments for education and training, intelligent tutoring systems, data science, and digital transformation.
