Social networks have drastically changed communication between people, constituting a means of everyday use by which information is created and shared in a simple, instantaneous way with the rest of the world. Although social networks were not initially created for academic purposes, they are gradually being used as a means of communication between teachers and students, making them an extremely important element in the teachinglearning process by offering new possibilities for communication and interaction as well as creating new learning spaces. The purpose of this study is to analyze the use of social networks as a communication tool between teachers and students through a thorough bibliographical review. To do this, a systematic review of scientific documents containing data on teacher-student communication through social networks was carried out, resulting in a total of 96 documents published between 2006 and 2016 indexed in different internationally consulted databases. From the analyzed documents were extracted the educational levels in which research on teacherstudent communication in social networks were carried out; the most addressed social networks in the study of teacher-student interaction through social networks; the research areas that have been developed and the main results. INTRODUCTION Social networks have changed the way people communicate, the interaction they have and the ability to create and share information with the rest of the world, becoming a daily occurrence (Gómez, Roses, & Farias, 2012). Social networks foster the maintenance, development and creation of interpersonal relationships based on the elaboration of a personal profile in which accessible information is published and shared by all who are present on the social network (Kwon & Yixing, 2010). Social networks have gradually emerged as a new avenue of communication between teachers and students, mainly in higher education, becoming an important communicative tool (Akcaoglu & Bowman, 2016; Albayrak & Yildirim, 2015; Chromey, Duchsherer, Pruett, & Vareberg, 2016), generating diverse questions about teacher-student communication through social networks and their impact on the teaching-learning process (Hershkovitz & Forkosh-Baruch, 2013). The use of social networks provides the opportunity for teachers and students to be in continuous contact transcending the conventional classroom and creating new teaching and learning spaces (Ean & Lee, 2016; Hamid, Waycott, Kurnia, & Chang, 2015). However, this new reality has generated debates as to whether teachers and students should interact in this way, leading some authorities to restrict or even prohibit such communication (Asterhan & Rosenberg, 2015). Supporters of the teacher-student interaction through social networks present arguments in favor, such as teachers´ and students´ freedom of expression, the inevitability of the phenomenon and the pedagogical potential of social networks (Greenhow, Robelia, & Hughes, 2009). As the number of teachers with social network profiles increases, the possibilities for teacher-student interaction increase. Therefore, if teachers wish to take advantage of the educational opportunities of social networks, both teachers and students should interact on them (Teclehaimanot & Hickman, 2011). The main purpose of the present study is to analyze the use of social networks as a communication tool between teachers and students through a systematic literary review. In particular, this study intends to answer the following questions: (1) What are the educational levels that are being addressed in research related to teacher- TOJET: The Turkish Online Journal of Educational Technology – October 2017, volume 16 issue 4 Copyright © The Turkish Online Journal of Educational Technology 127 student communication on social networks? (2) Which is the most commonly used social network as a communication tool between teachers and students? (3) What are the research areas that are being developed regarding teacher-student interaction through social networks and the main results of the studies under analysis? METHODOLOGY They were analyzed 96 published documents on teacher-student communication through social networks. These documents were found in international scientific databases such as Web of Science, Scopus, PsycINFO and ERIC and come from around the world. As standard criterion, it was established that all scientific documents that provide data on teacher-student communication through social networks would be analyzed, in order for all studies under analysis to be comprised of articles from scientific journals subject to peer review, doctoral theses, dissertations, conference communications and book chapters. The search criterion of the documents consisted of the detection in the title or abstract of the documents of the following keywords, some of them extracted from the ERIC and UNESCO thesaurus: “Teacher-Student Communication and Social Networking”, “Teacher-Student Interaction and Social Networking”, “Teacher-Student Relationship and Social Networking”, “Teacher-Student Communication and Facebook”, “Teacher-Student Interaction and Facebook”, “Teacher-Student Relationship and Twitter”, “Teacher-Student Communication and Twitter”, “Teacher-Student Interaction and Twitter” and “Teacher-Student Relationship and Twitter”. Similarly, new searches were carried out using other keywords such as “Teacher-Student Friending”, “Teacher Credibility”, “Instructor Credibility”, “Teacher Self-Disclosure” and “Student Self-Disclosure” in combination with the above mentioned keywords. From the total of the found documents, it was considered that 96 documents strictly met the criterion, the rest were excluded from the bibliographic review. The documents that were selected for the analysis cover the period between 2006 and 2016, both inclusive, since research focused on teacher-student communication through social networks has been carried out since 2006 and no studies have been found prior to this date. The selected documents were analyzed using a coding table in which they were categorized by certain features such as the educational levels that were addressed in the study of teacher-student communication on social networks, the most analyzed social networks in teacher-student interaction and the main results obtained by the studies under analysis. In order to create the categories, researchers followed an inductive process based on the exhaustive analysis of the content in the selected documents. RESULTS In relation to the educational levels in which research on teacher-student communication on social networks are being developed (see Annex 1); the results show that 77 studies have focused on higher education, 12 in secondary education and 4 in elementary education. There are 3 studies that have not specified the educational level in which the studies were carried out (Table 1)
