Semantics driven interaction using natural language in students tutoring
2007
The aim of this work is to introduce a semantic integration between an ontology and a chatbot in an Intelligent Tutoring Systems (ITS) to interact with students using natural language. The interaction process is driven by the use of a purposely defined ontology. In the ontology two types of conceptual relations are defined. Besides the usual relations, which are used to define the domain's structure, another type of relation is used to define the navigation schema inside the ontology according to the need of managing uncertainty. Uncertainty level is related to student knowledge level about the involved concepts. In this work we propose an ITS for the Java programming language called TutorJ…
DOCTORAL: THE FREE APP FOR TUTORING IN SUPPORTIVE ORAL CARE
2018

Emulating Human Supervision in an Intelligent Tutoring System for Arithmetical Problem Solving
2014
This paper presents an intelligent tutoring system (ITS) for the learning of arithmetical problem solving. This is based on an analysis of a) the cognitive processes that take place during problem solving; and b) the usual tasks performed by a human when supervising a student in a one-to-one tutoring situation. The ITS is able to identify the solving strategy that the student is following and offer adaptive feedback that takes into account both the problem's constraints and the decisions previously made by the user. An observational study shows the ITS's accuracy at emulating expert human supervision, and a randomized experiment reveals that the ITS significantly improves students' learning…
A combined semantic-syntactic sentence analysis for students assessment
2010
TutorJ is an Intelligent Tutoring System able to fulfill the requests of a student with a learning path inside didactical materials. To this aim, it must assess the level of training of the learner. In the first version of TutorJ this goal was reached through a conversational agent whose linguistic interaction enriched by a LSA-based text analysis. This approach suffers from the limitations of LSA as a bag-of- words approach. Next, morphosyntactic comparison of sentences' structures was implemented. In this paper we present a new version of the assessment procedure involving both semantic, and morphosyntactic analysis user's sentences.
A Map-Based Visualization Tool To Support Tutors In E-Learning 2.0
2009
Web 2.0 regards essentially the social issues about the new usage of web applications, but participative web and user generated contents induce a new way to think about the design of the web applications themselves. This is particularly true in the field of educational systems that are all web based applications. Many researchers are now devoted to study what is called e-learning 2.0 both as regards the technological issues in the field of computer science, and in relation to the impact of the web 2.0 social and psychological issues on the education process itself. One of the most crucial topics in e-learning 2.0 is the way to provide support to the teacher/tutor to avoid cognitive overload…
The master’s dissertation viva by video conference: strategies and best practices
2019
Durante la última década, se han publicado numerosos estudios sobre el proceso de elaboración y evaluación de los trabajos de fin de máster (TFM) (Da Cunha, 2016; García & Martínez-Clares, 2012; González-Calero & Turégano, 2011), sobre las fases de tutorización y acompañamiento al estudiante (Flores, Martínez, Martínez López, Pascual, & Sanz, 2013) y sobre las competencias a adquirir tras su finalización (Cabrera, Sangrà & Rodera, 2012; Serrano & Pontes, 2015; Viejo & Ortega Ruiz, 2018). Sin embargo, no resultan tan evidentes las investigaciones que analizan la fase de preparación y defensa pública de estos trabajos, siendo, sin embargo, la que genera más incomodidad entre el estudiantado. …
Domain-specific knowledge representation and inference engine for an intelligent tutoring system
2013
One of the most challenging steps in learning algebra is the translation of word problems into symbolic notation. This paper describes an Intelligent Tutoring System (ITS) that focuses on this stage of the problem solving process. On the one hand, a domain specific inference engine and a knowledge representation mechanism are proposed. These are based on a description language based on hypergraphs, and the idea of using conceptual schemes to represent the student's knowledge. As a result, the system is able to simultaneously: (a) represent all potential algebraic solutions to a given word problem; (b) keep track of the student's actions; (c) univocally determine the current state of the res…
Using System Dynamics to Model Student Performance in an Intelligent Tutoring System
2017
One basic adaptation function of an Intelligent Tutoring System (ITS) consists of selecting the most appropriate next task to be offered to the learner. This decision can be based on estimates, such as the expected performance of the student, or the probability that the student successfully solves each particular task. However, the computation of these values is intrinsically difficult, as they may depend on other complex latent variables that also need to be estimated from observable quantities, e.g. the current student's ability. In this work, we have used system dynamics to model learning and predict the student's performance in a given exercise, in an existing ITS that was developed to …

Opettajaopiskelijoiden kielitoinen toimijuus monikielisten oppijoiden etäohjauksessa
2022
Artikkelissa tarkastellaan opettajaopiskelijoiden kielitietoista toimijuutta ohjaustilanteessa, jossa he tukevat etäyhteyksin eri-ikäisiä monikielisiä oppijoita. Ennestään tuntemattomien monikielisten oppijoiden ohjaaminen etäyhteyksin oli opettajaopiskelijoille uusi ja haastava tilanne pandemiakriisissä vuonna 2020. Tutkimuksen aineistona on yhdentoista opettajaopiskelijan ohjaustehtävästä kirjoittamat raportit, jotka on analysoitu aineistolähtöisen temaattisen analyysin keinoin. Analyysissa tarkasteltiin seikkoja, jotka mahdollistavat ja rajoittavat varhaiskasvatuksen, luokanopettajakoulutuksen ja kielten aineenopettajakoulutuksen opiskelijoiden kielitietoista toimijuutta monikielisten op…
