This research frames a descriptive study that aimed to identify strategies for the implementation of Virtual Learning Objects-VLO-in the Faculty of Humanities of the University of San Carlos of Guatemala; to identify the best strategies, we used the qualitative case study methodology, divided into two phases. In the first one, the video interview technique was applied to experts in virtual learning objects from 11 Latin American Universities, from Chile, Argentina, Panama, Colombia Costa Rica, Mexico and Guatemala, in order to establish a benchmark of success stories In the use of VLO. Then the second phase consisted of structuring the results with the purpose of generating a proposal for the implementation of VLO, through innovative strategies in the Faculty of Humanities-USAC-, This proposal validated by the experts who constituted the sample, proposes a model of 5 levels based on the Rogers theory of dissemination of innovations applied to processes of virtual formation.

We present a systematic mapping, also called science mapping, to identify major areas of research activities concerning Learning Technology and the evolution from one area to another. The purpose of this work is to compare international tendencies with the LACLO community. The systematic mapping is primarily guided by author's keywords co-occurrence in the dataset selected. The scope of the data is limited by the sources of the literature used, in this case the LACLO and ICALT conferences and relevant Journals in the area, between years 2009 and 2016. We use the SciMat tool for this purpose and we present the analysis performed in the field of Learning Technology. Finally, some visual analytical studies of the identified areas and the relationships between them are presented. Incorporating the evolutionary stages of a specialty into the visual analytic study of the Learning Technology research domain is valuable. It provides a systematic methodology for researchers to achieve a good understanding of how the field evolves, to recognize potentially insightful patterns from visually encoded signs, and to synthesize various information so as to capture the state of the art of the domain.

The use of Flipped Classroom (FC) model supported with technology has allowed to optimize classroom time, covering the students' learning demands and adapting to their work pace. However, learners perform at different pace and use external resources during their learning, which requires from them the ability to self-regulate. In this paper, a pilot study is presented and investigates how students with different self-regulation profiles navigate through a MOOC when it is used as a part of FC methodology. To meet the study objectives, by using Process Mining techniques, it has been investigated over log files recording the course behaviour of N= 149 learners across an Open edX MOOC used to support FC. The findings show that learners who were exposed to the FC obtained better grades than their counterparts. Also, learners with different SRL profiles follow different navigation paths. This study opens up the possibility to other researchers to explore how learners perform in a MOOC using FC.

The number of Brazilians who are enrolled in educational distance courses has increased significantly in recent years. This type of education has as great ally, the Internet. Unfortunately, in Brazil the majority of the population has no access to the Internet in their home, which is an obstacle for those who want to take a distance education course. The present work explored the features offered by Brazilian Digital TV to implement a high fidelity functional prototype of the T-MindMap application, which offers discussion forums through mental maps as an tool to the teaching and learning process in the distance education model.

The quality control in software applications that support the teaching-learning process is of great impact to the end user and their academic success. This paper describes the proposal of a quality control model called TD-CCS, implemented in a Learning Management System dotLRN, adapted for the development of applications in TEC-Digital. For measurement purposes, a data analysis was applied to ten projects in TEC-Digital, using evaluation criteria, aspects of documentation, structural quality of packages, functionality, web navigability, security and performance, integrity and compatibility. From the study it was obtained that in the test stage a total of 454 findings were captured, reflecting the importance of optimizing software quality in the early stages, as well as the need to define objective metrics that allow an integral quantitative analysis.

Education needs to provide the means and resources to respond to new forms of education in which Information and Communication Technologies are implicit. Teaching experiences that make innovative and creative use of technology underlie a series of common ideas and pedagogical approaches that seek to harness the full potential of these technologies, framed in a new culture of learning. These are called emerging pedagogies. Open Educational Resources refers to educational materials and resources in free digital support and free access through Internet (texts, audio, video, software, etc.). Learning Objects are consolidated as open digital resources to encourage active learning. This paper presents, as an innovative pedagogical proposal, the design of an Learning Object to support teaching and learning processes of Simulation using emerging pedagogies approach.

Learning Analytics focuses on improving learning process by studying and analyzing data produced during the process itself. It covers the collection, measurement, analysis, reporting and knowledge discovering on data about students, teachers and institutions. Learning Analytics has been widely developed in Anglo Saxon countries. USA, United Kingdom, Canada and Australia are amongst the main contributors to this domain. Latin America is also starting to measure and optimize teaching and learning processes through Learning Analytics; however, the existing attempts in this direction are very isolated as there is a lack of a regional community to foster the interchange of ideas, methodologies, tools and local results in the field. The present work is a first attempt to identify Learning Analytics initiatives in Latin America by conducting a systematic mapping of papers from Latin American authors, and also by analyzing data about research groups from Latin America (collected through an open survey). In total, we categorized 30 articles published from 2011 until May 2016, and we analyzed data from 28 research groups that answered the open survey.

The high failure and dropout in programming courses all over the world is around 30%. The Bachelor of Information and Communications Technology of the Federal University of Santa Catarina has failure rates up to 80% in recent years. Although there are several studies around this topic, a few of them discuss the academic tutoring for these courses. The concern with the student dropout is a major challenge for both public and private universities. The main goal of this paper is to analyze the student's and tutor's perception of the tutoring activities to identify the main actions to engage and motivate them in programming courses. We investigate the academic tutoring program during three semesters and proposed a different kind of activities during this time. We found that students have solitary habits of studies and look for the tutors only a feel days before the tests or exams. Our results also show that despite the initial contact between tutors and students, the students liked the presence of the tutors during the classroom. Another interesting result is that the creation of an email for asynchronous communication or web conferences, it was not used as student suggested. Only two emails were sent in a period of three months. This is something that must be investigated.

The use of serious games as a mediator to the learning process has risen a lot over the last few years. This article goes beyond, by using the act of building a serious game as a learning construct. It introduces an educational game that helps the user to learn about art, history and architecture. This game was developed using the Challenge Based Learning method (CBL), which has been applied in elementary school in several places around the world, but it is still novel in the college environment. The development process and the game are presented in detail in many learnings that have risen from this process are described.

In this work we propose a recommender system of Open Educational Resources focused on the pedagogical intention of the learning session that the teacher designs. The Recommendation System considers the Taxonomy SOLO to identify the verb that directs the pedagogical intention of the teacher in his/her learning session. The verb unfolds the corresponding cognitive processes and the system suggests the most appropriate learning resources according to the educational purpose of the teacher. This work proposes an architecture of the recommender system that includes the use of LOM metadata to describe the resources with the addition of a metadata that allows assigning the verb (s) that the resource fulfills.
