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.

Transmedia podcasting (transpodcast) is an example of a digital medium essentially promoted by a community of independent creators that arises from the technological advancement derived from the arrival of Web 2.0. This medium is considered to offer its users greater possibilities of participation and co-creation by abandoning the traditional communicative models based on unidirectionality. The objective of this work is to determine how audience engagement takes place in this medium, taking into consideration the analysis of its participation spaces. In order to reach this goal, a Mixed Method Research Design was used, integrating two case studies with a total sample of 2,490 units of participation generated by users on the iVoox platform, the blogs of the two selected projects, and messages on Twitter. The research was complemented with an ethnographic investigation through observational methods on the presence of the user's voice in the podcasts of a total of 19 transpodcast projects. Despite the fact that numerous and relevant voices have defended that the new media ecosystem causes the decentralization and democratization of the agenda-setting and empowers ordinary citizens, this study shows a less optimistic and more critical perspective about the possibilities of meaningful citizen participation in online discourse.

This study analyses the role of communication in social activism from models that surpass the mere emotional reaction, prior belief reinforcement or brand identification. This paper tests the hypothesis that a message focused on the cause (and its results) will motivate a previously sensitized audience depending on their interactions with source favorability. The methodology is based on the design of a bifactor experimental action result study 2 (failure versus success) x 2 valences (favorable versus unfavorable source) with the participation of 297 people who are pro-avoidance of evictions. The results allow us to infer that the messages from sources hostile to the cause that report negative results have the potential to emotionally and behaviorally motivate activists to a greater extent than messages with more positive results from favorable sources. The conclusions point to the dialogue between social injustice frames and pro-cause action emotions as a way to increase social mobilization. The theoretical and empirical implications of these findings are discussed in the present-day context of social media prevalence. [ABSTRACT FROM AUTHOR]

Does the public expression and performance of shock, distress, anger, frustration and ideological disapproval of particular sorts of politics constitute a form of collective political expression from which individuals can learn about being citizens? When it comes to the expression of feelings of racial and other types of prejudice, has political correctness led to a deepening of entrenched racist beliefs with no channel for discussion? This article engages with such questions through a case study of YouTube responses to «My Tram Experience» a commuter-uploaded mobile-phone video of a racist diatribe on a tram in the UK. Using qualitative content analysis and thematic analysis, it describes how these performed, networked and distributed moments of citizen angst demonstrate a limited but interesting range of civic engagements with and positionings towards racism, immigration, class and nationalism. For one reason or another these are not allowed to occur in other public for a such as the mainstream media or schools. The article argues that these vlogs are both a wide-ranging potentially therapeutic resource for those needing validation for their racist or anti-racist views, or for those who wish to express and garner solidarity for discomfort and pain caused by racism; they are also a significant though currently uncurated resource for citizenship education both formal and informal because of their engagements with technology, social context, emotional context and political rhetoric.

This essay examines the relationship between player and diegetic sound FX in immersive computer game environments and how this relationship leads, in large part, to the contextualization of the player within the virtual world of the game. This contextualization presupposes a primarily sonically-based perception of objects and events in the world and, in a multi-player game, this ultimately leads to communication between players through the medium of diegetic sound. The players' engagement with, and immersion in, the game's acoustic environment is the result of a relationship with sound that is technologically mediated. The game engine, for example, produces a range of environmental or ambient sounds and almost every player action has a corresponding sound. A variety of relevant theories and disciplines are assessed for the methodological basis of the points raised, such as film sound theory and sonification, and, throughout, the First-Person Shooter sub-genre is used as an exemplar. Such games include the «Doom» and «Quake» series, the «Half-Life» series and derivatives and later games such as «Left 4 Dead». The combination of the acoustic environment, the interactive placement of the player - as embodied by his virtual, prosthetic arms - in the environment and the sonic relationships between players produces the acoustic ecology. An exposition of this multi-player communication and the resultant acoustic ecology and player immersion, is the main objective of the essay. [ABSTRACT FROM AUTHOR]

One of the specific challenges faced by media education in Latin America is to narrow the divide and promote more equitable, fairer access to cultural and technological commodities among youth from the poorest families. Although the obstacles are more than a few and the challenges are by no means negligible, the first step toward facing them is to insert Media Education as a public policy, as State policy. Fortunately, we have always had teachers who have used the media and taught others to analyze, interpret and use them creatively. The idea, when Media Education becomes part of public policy, is to move beyond individual initiative and turn these private efforts into a State commitment. This is the only way to overcome the huge obstacles and materialize the major challenges posed by media education in the 21st century. [ABSTRACT FROM AUTHOR]

This paper is a reflection on the adaptation of the spectator to the latest tendencies in plastic art and image in general. This reflection leads up to consider the need for helping the audience to become critical spectators. This proposal is based on the development of activities, some of which have already been put in to practice, which are aimed at the audience with the goal of producing an active learning process. Apart from the participants' personal involvement, motivation should be the focus of the activities. [ABSTRACT FROM AUTHOR]
