Title- Early Introduction of Robust Control Concepts: Hands-on Experience and CAD

Abstract- This paper presents an educational experience in an initial course in feedback control. The purpose is to introduce concepts of robust design not included in the regular curriculum. The problem of designing a controller for a simple mechanical system without knowing the true value of the parameters is proposed in a laboratory class. The task is performed on the real system with the aid of CAD freeware. The combination of practice and software tools, encourages the development of autonomous learning and favors the apprehension of the concepts of uncertainty and robustness. A perception survey shows promising results indicating that the strategy of learning by doing is very well accepted by the students.

Title- Use of repositories of digital educational resources. State of the Art Review.

Abstract- Repositories of digital educational resources have reached a significant level of development and diversification in the last decade to the point of becoming a central component in higher education transformation. This paper presents a State of the Art Review of the studies about the use and adoption of digital educational digital resources repositories. Some quantitative approaches mainly collect metrics related to the publishing and reusing of educational resources. However, there is still insufficient empirical evidence to account for the types of adoption and use of educational repositories. There are few studies aimed at determining which are the dimensions of adoption educational resources repositories by scholars, how educational repositories' adoption overlaps in teaching practices and which subjective, contextual, institutional, curricular and instructional factors are involved in the different types of use.

Title- Educational Repositories: Study of the current situation and Strategy to improve their effective use in Ecuadorian Universities.

Abstract- Educational Repositories of Digital Educational Material allow teachers and students to access to educational resources, to be used in virtual learning environments. The objective of this study is to explore to what extent Ecuadorian universities make use of educational repositories, specialized repositories of Learning Objects and the way in which they have evolved over the last five years. The study also aims to identify barriers and factors that hinder their use. It is expected that the conclusions drawn from this analysis will allow the design of strategies aimed to promote the creation and use of quality digital educational materials.

Title- An Assistant to populate Repositories: Gathering Digital Objects and Metadata Extraction.

Abstract- This paper presents an assistant to populate Institutional Repositories. This tool can detect all educational digital objects in text format that are already published on institutional websites and can be uploaded to a repository. This recopilation is a tedious task and is usually performed manually. In this paper we propose a system architecture for automating this task of collecting text documents within a restricted domain in order to detect plausible documents that can be loaded into a repository. Also, its metadata such as language, category, title, authors and their contact data are automatically extracted. A prototype of this system was developed and case studies in two different domains are analyzed.

Title- Metadata for Educational Games in Online Repositories

Abstract- In this paper, we describe the special challenges that educational games (aka serious games) pose for online Learning Object (LO) repositories. As in all metadata, a tension exists between descriptive power and the effort needed to create these descriptions. This tension is even greater when describing complex, highly interactive multimedia content such as serious games. We consider serious games as LOs, proposing game-specific metadata, and advocate for game authoring tool support that streamlines its creation.

Title- Learning Object Metadata Mapping in Learning Styles as Strategy for Improving Usability of Educational Resource Repositories.

Abstract- One of the topics that generate interest in the community is the possibility to relate the characteristics of students with the type of material that best suits your learning style, interests and preferences. This topic holds most importance in systems that perform automatic selection of materials and educational activities and thus improving the usability. The proposal presented in this article is directed to the personalized selection of learning objects according to the student Learning Style. The proposal and some of the tests that predict good outcomes in diverse systems is presented.

Title- Towards the implementation of relevance and reputation indicators in Edu-AREA.

Abstract- This paper introduces the first implementation of relevance and reputation rankings in Edu-AREA. This Web 2.0 application promotes users creating, viewing, adopting, adapting and curating elements in an open way, following the principles of the OER movement. A main issue is the management and control of quality. Users can provide elements freely and some mechanism that can estimate or rank their quality is needed. A solution based on usage by other users inspired in the HITS algorithm is adopted. Taking into account the usages of the elements, a relevance measure for each element and a reputation measure for each user are calculated.

Title- Selection and use of search mechanisms in Learning Objects Repositories: the case of Organic.Edunet.

Abstract- Difficulties in finding learning objects (LO) in LO Repositories (LORs) are one of the main barriers which avoid LORs to be globally adopted. During Organic.Edunet European research project different search interfaces were developed with the intention of facilitating the location of LOs, considering users would tend to use different interfaces, according to the objectives and specific search context. This paper resumes the results of a usability study carried out in Organic.Edunet portal where users were asked to complete different search tasks that were clearly oriented to the use of one of the existing interfaces and provides a snapshot about how this knowledge was transferred to Organic.Lingua project.
