European researchers have developed a learning environment to help students better understand science subjects by building conceptual models. The tool is interactive and is based on the use of semantic resources.
Eight European universities, among which is the University
of Madrid through its Faculty of Information Technology (UPM) have developed a
new software tool that helps students build conceptual models of the scientific
subjects of their study, individually or in a collaborative environment, using
semantic resources.

At the same time, the tool allows you to store these new
models and compare with other existing models in order to help students
define concepts related to an area of knowledge.
All this information allows students to improve their
models, gaining a better understanding of the domain to represent. Thanks to
these techniques, students gain in autonomy without losing rigor and can
significantly advance the study of a subject.
This interactive learning environment is part of the
European project DynaLearn, which aims to contribute, by integrating
well-established technological developments, to arouse the interest of young
Europeans in the study of scientific disciplines. One of the achievements
"more relevant" project, according to its promoters is the use of
semantic resources that help students define and understand the concepts
represented.
The project is nearing completion and already has an
advanced prototype of the tool, which has been successfully tested in real
scenarios for learning in classrooms from seven different universities.
Using semantic resources
DynaLearn uses external semantic resources as a
source of information. Among them is DBpedia, which extracts data from
Wikipedia to create a semantic version of the same: it is a community effort to
extract structured information from Wikipedia and make it accessible from the
Web. In this way ensures that the collected knowledge can be exploited
computationally. There is now a large number of applications that link to
DBpedia, making it possible to establish common vocabularies between them and
facilitate their interoperability.
DynaLearn allows you to find correspondences
between the terms introduced by students and collected in DBpedia
The project DynaLearn allows you to find
correspondences between the terms introduced by students and collected in
DBpedia. When creating models, students can check the definitions obtained
from DBpedia to its terms correspond to what they expected or not.This helps
them improve and correct terminology possible misinterpretation.
The application can also save models created by students,
teachers and other experts, thus forming a model repository. Prospective
students can take advantage of the knowledge of these models to improve their
own. For this, the system automatically selects those models that may be
relevant to the student model is built. The relevance of the models is
calculated according to a set of criteria that are based both on the similarity
with the student model, as in the reviews that other users of these models made
in previous executions.
You can then analyze the similarities and differences
between the models selected and the student model in order to suggest possible
improvements to it. All this information allows students to complete their
models, gaining a better understanding of the domain to represent.
Thanks to these techniques, students adapt the learning
process to their needs. In addition, high interactivity and ease of
DynaLearn make the experience more enjoyable, increasing the motivation of
users and accelerating the uptake of new knowledge.
The tool is available online at the project website. The
semantic repository access requires registration. Currently this report
may be obtained from the creators, both for private use as schools. There
is also a set of demonstration videos and teaching materials in a web.
Reacting to the educational needs
The aim of DynaLearn is developing a
interactive learning environment that has three key features: accommodates the
use of conceptual knowledge to the learning experience, its use is attractive
to students and responds to individual needs of each student's knowledge
The developed software improves students' ability to
understand and explain the behavior of scientific systems. On the other
hand, the use of virtual characters encourages students to use the software,
encouraging them to cooperate and compete with each other and encouraging
social component of learning.
Semantic technology also allows students to compare their
results automatically with the models created by other students or their
teachers, learn about how to improve them and recommend a customized learning
path.
DynaLearn is a project of the Seventh Framework
Programme for Information Technology and Communications (FP7-ICT) of the
European Union, coordinated by the University of Amsterdam and with the
participation of the Ontology Engineering Group School of Computing led by
Asunción Gómez, University of Augsburg, the University of Brasilia, Tel Aviv
University, the University of Hull, the Bulgarian Academy of Sciences and the
University of Natural Resources and Applied Life Sciences Vienna.
