Currently, and increasingly, education uses technology to support teaching and learning processes, the present work shows a system to determine the best instructional techniques, taking into account students' learning styles, using a modification of the Felder and Soloman test. This modification, called FuzzyILS, was performed by Silva, Vicari and Ponce in 2016, and proposes the fuzzy of Felder and Soloman test, to determine the degree of belonging of a student to each dimension in the Felder and Silverman learning styles. In the work the method called FuzzyILS-Instruction is explained, the evaluation is performed and a comparison is made with the results obtained in the previous method, which does not implement the original Felder and Soloman test, called MeLOTS.
目前，教育越来越多地使用技术来支持教学和学习过程，目前的工作展示了一个系统，以确定最佳的教学技术，考虑到学生的学习风格，使用费尔德和所罗门测试的修改。这种修改被称为FuzzyILS，由Silva, Vicari和Ponce在2016年进行，并提出了Felder和Soloman测试的模糊，以确定学生对Felder和Silverman学习风格中每个维度的归属程度。本文对FuzzyILS-Instruction方法进行了说明，并对该方法进行了评价，并与未实现原始Felder and Soloman测试(MeLOTS)的先前方法的结果进行了比较。

Concept Maps, proposed to help understand how children assimilate new concepts, has proved to be a powerful tool for representing, organizing and building knowledge. Other lines of research focus on the use of Intelligent Agents, not only in the educational area, but in different environments. This work proposes an agent-based approach for the construction of concept map, associating simplicity and richness of maps with dynamic and interactivity of agents.

In an Intelligent Tutoring System (ITS), the graphical user interface is the main mode of interaction between the program and the user. Thus, it is important to evaluate its usability, which is the system's efficiency and ease of use. For these evaluations, methods such as Nielsen heuristics and questionnaires are more recurrent. However, such procedures cannot detect problems that were not foreseen by the experimenters. This paper presents a case study using the protocol Think Aloud for the usability evaluation of the ITS PAT2Math. The case study showed that the protocol allows to obtain previously not foreseen information in relation to both functional questions of the graphical interface and to the emotions of the users. Think Aloud revealed to be an interesting approach to a formative evaluation of ITSs and other computer learning environments.

It is essential for a constructivist teacher to monitor the apprenticeship of each student in order to facilitate the definition of the next steps in the development of a discipline. Since monitor the apprenticeship is a very complex and time-consuming task, a theoretical framework that supports the observations of the teacher becomes necessary. The use of concept maps to record a students understanding of a subject can simplify this process a lot. In the construction of concept maps, when we are choosing a relationship between two concepts, we are creating, ultimately, what Piaget calls “a meaningful implication” that evolves according to the semantic nature of the relation that we create. We propose here, via a specific tool, an environment for the automatic identification of the meaningful implications in a concept map made by a prototype.

Just a few decades ago the society has been interested in the field of children's rights. For this reason, the society as a whole has been developing strategies to achieve that commitment. As a result, it has given more attention to this society segment that is vulnerable. With this the society does not pretend to expose the individual in the early stages of his life. The way in which children live is critical in his formation when he reaches adulthood. Considering this, every field of study must be present with a childhood approach to the early stages of life. Hoping to contribute to build better generations. In the area of serious games we have better opportunities, because the games are a major part in the early stages of life and are present regardless of race, culture, religion or social status of the children. The multiple factors involved in shaping the character of children are out of their control. They are so many and varied that it becomes difficult for a child gets out unharmed. Although it is part of the natural formation of each individual processes it is different and therefore, is affected in a special way. This paper presents a serious game prototype used as an aid in the treatment of children with emotional disorder, particularly in children with some sort of depressive behavior.

Nowadays there is a worldwide interest in introducing notions of programming in basic schooling. In line with this, different training programs have been proposed to allow the appropriation of these novel contents. This paper presents a proposal for interdisciplinary training in computer programming for primary school teachers, carried out in Argentina. Taking a socio-technical approach and from a sociocultural perspective of learning, a workshop about programming of technology for social inclusion (TIS) was designed using the Scratch tool. The preliminary results of this exploratory study allow us to identify different phases in the TIS construction process, where participants designed and programmed group productions, starting from problematic situations. In this way, teacher development proposal involved notions of programming, but also generated interdisciplinary pedagogical tools that can act as triggers for multiple activities within the classroom.

This electronic puppet is an assistive educational technology designed especially for non-oralized children. The purpose of this is article is present a project of assistive educational technology named Electronic Puppet. In order to do this, we use the electronic puppet, that fits in the concept of internet of things, connecting himself to the multimedia system with images, sound, animations and included in educational methodology based on Vygotsky's approach, the historical-social and cultural theory. The functional and educational results shows that this portable children storytelling tool, mediated by the Electronic Puppet, is appropriate to help children with cerebral paralysis or other learning or cognitive issues.

Digital Educational Materials have attracted the interest of both educators and researchers, since they have become significant links in the new educational scenarios, where there is mediation with digital technologies. This article focuses on a type of educational material, learning objects (LOs), that is oriented to reutilization. In particular, the design and implementation of a LO that stems from a concrete educational at the School of Computer Science of the National University of La Plata is discussed. The main goal of the LO is to help students understand the operation merge. Additionally, it is also aimed at encouraging students to learn about this topic and favor autonomous learning. The LO was developed with Ardora and eXeLearning, and it has undergone a first assessment by peers. The feedback received has resulted in the creation of a plan for future improvements.

One of the main issues related to the online distance learning courses is the method employed in order to connect students and professors. Two main forms of communication are normally chosen (or combined): synchronous and asynchronous. This paper aims to analyze the impressions of students and professors about the usage of both methods of communication on the specific context of Final Year Project discipline. A survey containing questions based on the three main constructs of the Technology Acceptance Model was applied for both groups of stakeholders (students and their supervisors). The survey aimed to identify impressions and preferences of those groups for one form of communication over the other. It was possible to observe that asynchronous communication (forum discussions) was highly rated by both groups in comparison to synchronous communication(chat discussions). At the same time, it is important to highlight that synchronous communication also obtained good ratings, indicating that the combination of both methods is well suited and complementary for this particular scenario.
与在线远程学习课程相关的主要问题之一是采用连接学生和教授的方法。通常选择(或组合)两种主要的通信形式:同步和异步。本文旨在分析在Final Year Project学科的具体背景下，学生和教授对这两种交流方式的使用印象。一项包含基于技术接受模型的三个主要结构的问题的调查应用于两组利益相关者(学生和他们的导师)。这项调查旨在确定这些群体对一种交流方式的印象和偏好。可以观察到，与同步交流(聊天讨论)相比，两组人对异步交流(论坛讨论)的评价都很高。同时，重要的是要强调，同步通信也获得了良好的评级，这表明两种方法的组合非常适合并互补于此特定场景。
