This paper constitutes a literature review that evidences that competency acquisition in higher education has boomed in the XXI century and that one of the competencies developed is research. The objective of this paper is to prepare a theoretical systematization of the years 1999-2013 using the existing research projects regarding the acquisition and development of research competence in higher education, based on its concept and the relationships between each of its components and dimensions. The research methods used were historical-logical and analytic-synthetic and the technique used was the document analysis of 40 papers by authors from Europe, Asia and the Americas. The paper presents a pedagogical analysis of the results obtained, identifies strengths and weaknesses, and proposes a number of pedagogical considerations to be included in the acquisition and development of this competence. The main result obtained is that neither a professional nor a technological component has been fully integrated to the research competence structure.

Massive and open online courses (MOOCs) satisfy learning needs from the particularities of their typologies (xMOOC, tMOOC, cMOOC, iMOOC, among others) even though their high dropout rate is still latent. Recent studies reaffirm engagement as an alternative to reduce dropout rates. The literature analyzed has not yet been able to systematize responses as to how to guarantee engagement in MOOCs and thus reduce their attrition rate. And, consistent with that question, are there still challenges for teachers in this area of educational technology? These answers motivated us to carry out this systematic review to determine how engagement has been studied to help reduce the attrition rate in MOOCs. Articles from journals indexed in Scopus or WoS were reviewed applying the PRISMA protocol. At the end of the protocol, it was defined to analyze 40 studies. The results reflect that the main variables are: the design of e-activities, intrinsic and extrinsic motivation, and communication between students. This paper confirms that the main challenges to guarantee engagement in MOOCs are individualized tutoring, interactivity, and feedback. Due to the scarcity of studies that analyze the variables in an integrated way, it is proposed as future work to determine what relationships exist between these variables that interfere with engagement and dropout in MOOCs. Los cursos en línea masivos y abiertos (MOOCs) permiten satisfacer necesidades de aprendizaje desde las particularidades de sus tipologías (xMOOC, tMOOC, cMOOC, iMOOC, entre otras), sin embargo, es aún latente su alta tasa de deserción. Estudios recientes reafirman el engagement como una alternativa para disminuir los índices de deserción. La literatura analizada aún no logra sistematizar respuestas a ¿cómo garantizar el engagement en los MOOCs y disminuir así su tasa de deserción? Y, en coherencia con esa pregunta, ¿existen aún retos del profesorado en este ámbito de la tecnología educativa? Ello motivó a realizar esta revisión sistemática para determinar cómo se ha trabajado el engagement para contribuir a disminuir la tasa de deserción en los MOOCs. Se revisaron artículos de revistas indexadas en Scopus o en WoS aplicando el protocolo PRISMA. Al finalizar el protocolo se definió analizar 40 estudios. Los resultados reflejan que las principales variables son: el diseño e-actividades; la motivación intrínseca y extrínseca y; la comunicación entre los estudiantes. Se ratifica que los principales retos para garantizar el engagement en los MOOCs son: la tutoría individualizada; la interactividad; y la retroalimentación. Debido a la escasez de estudios que analicen de forma integrada las variables antes mencionadas, se propone como trabajo futuro, determinar qué relaciones existen entre estas variables que intervienen en el engagement y la deserción en los MOOCs.

The future and already current industrial revolution 4.0 demand the introduction of a digital transformation in the higher education contributing to the formation of competent professionals, for which, they are evidenced in the pedagogies and emergent technologies, an increase of didactic experiences in the use of the digital social networks. In this research a systematic review to identify current trends in the use of online social networks for educational purposes are performed. PRISMA protocol was used and analyzed 79 studies present in the database Scopus. In the systematic review, the following questions are answered: What types of designs predominate in the scientific literature? What is the dependentindependent pairs of variables? And What are the current trends in the use of digital social networks for educational purposes? As a result of this research, Facebook is reaffirmed as the social network most used by educators and the need for the integrated and varied use of these networks. It concludes with the defense of the following trends: university institutional communication policies from the curricular levels; the development of creativity, cultural convergence and media diversification; educational innovation; media culture and academic digital identity

The objective of this article is to determine which are the international standards and norms of usability that are used in educational technology applied to the teaching of mathematics at secondary and higher education levels, focused on two scenarios: (1) digital educational resources and virtual learning environments (VLEs), and (2) game-based learning. The PRISMA protocol was used and the Scopus and IEEE Xplorer databases, the Springer publishing House and the ACM Digital Library were used for the search strategy. Forty-seven primary studies were selected, emphasizing the use of the ISO/IEC 9241-11 standard. However, the isolated use of criteria to usability assessment without achieving engineering integration is reflected. Primary studies in the teaching of mathematics mainly use the ISO 9241-11:2018 and ISO/IEC 9126-1:2004 standards. Game-based learning scenario uses ISO 9241-11:2018 standards and procedures that guarantee, at least, the integration between efficiency, effectiveness, and ease of use. Digital educational resources and VLEs scenario uses ISO/IEC 9126-1:2004 and ISO/IEC 9241-11:2018 standards, and procedures that guarantee at least the integration between efficiency and ease of use; effectiveness and ease of use; ease of use and accessibility; and effectiveness, ease of use, accessibility, and efficiency.
