However, this global performance is not an important factor for the end-user of the system. For the end-user, the performance of the model for his or her specific case is the most important aspect of that model. Given that the model is usually selected at design time, the end-user could end up with a sub-optimal prediction. To solve this problem, this work presents a conceptual framework to build adaptive multilevel clustering models for academic risk prediction. This frameworks allows the system to automatically select between several levels of hierarchical or semi-hierarchical features to create a clustering model to best predict the particular risk of each student. This conceptual framework is validated through its realization into an adaptive model to predict the risk of failing a course during a semester in a Computer Science program. In this study, the adaptive model consistently outperforms the prediction of the best-performing static model.","PeriodicalId":271823,"journal":{"name":"2016 XI Latin American Conference on Learning Objects and Technology (LACLO)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132527120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our implementation approach is made up of three components: A user model based on the descriptions of the lessons of a course given in an Instructional Design (ID), a serie of items which constitute the metadata bank of resources described using IEEE Standard for Learning Object Metadata model (IEEE-LOM) and harvested by Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) and finally, an utility function derived from the weighting between the collaborative assessment of LO and similarity measures to compare LO's metadata with descriptions of activities given for course.

This paper describes the functionality of the Collaborative Logical Framework and the redesign made by the TEC Digital Tecnológico de Costa Rica (TEC) which aims to aid students and teachers to reduce the problems that can be generated working in groups, through a tool integrated in a LMS applying usability criteria on web and mobile platforms and some integrations with others applications on .LRN LMS. This was validated applying a survey to grade and postgrade students at the TEC.

This paper presents the development of an educational game covering the issue of misspellings of children in the literacy process and the use of the interface by gestures, such as motivation and attraction to the educational environment. The application developed was tested with children of the second year of elementary education at a private school in São Paulo and usability rating is described in this paper.

It takes as case study the community of university teachers that had participated in the Learning Object Contest developed in the LACLO Conference in its 2012, 2013 and 2014 editions. Results show that 283 individuals had participated in LACLO's Learning Objects Contest during the period reviewed, coming from 49 Higher Education Institutions of 10 countries. They are mostly women, and 25 academic disciplines are identified. From the data collected it is possible to make a projection about a characterization of users of digital educational resources repositories in Latin America. This exploratory study will be improved with future qualitative studies, deepening the knowledge on individual experiences, in order to know the dimensions of the adoption of digital educational resources repositories in the Latin American region.","PeriodicalId":271823,"journal":{"name":"2016 XI Latin American Conference on Learning Objects and Technology (LACLO)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116892459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, authenticity methods of learning objects has not been widely adopted by repositories, making it difficult to verify the authors of the content. To solve this problem, our goal is to aid users and authors of learning objects to have a trusted verification of authenticity and versioning of learning objects by applying digital signatures into the lifecycle of learning objects. In our propose, after a learning object is uploaded to a repository, the author presents his/her digital certificate, a special LOM record is created with the information from the author's certificate, and then it is signed to prove its authenticity. The signature is produced using digital certificates issued by the digital signature infrastructure of Costa Rica, which guarantees legal binding and trust over time.
