“…Guo et al (2015) believed that OER is the bundle of learning resources that can be used and adjusted by the user without any legal and economic restrictions. Jung and Hong (2016) defined OER as study materials with an intellectual property license that permits repetition in use and distribution. Additionally, OER include full courses, programs, syllabi, curricula, teachers' guides course materials, modules, learner guides, teaching notes, textbooks, e-texts, research articles, videos, audio tracks, assessment tools and instruments, interactive materials such as simulations and role plays, experiments, demonstrations, databases, software, apps (including mobile apps), and any other materials that have been designed for use in teaching and learning used to support access to knowledge that is openly available for use by educators and learners, without an accompanying need to pay royalties or license fees (Atkins et al, 2007;Hylén & Schuller, 2007;UNESCO, 2002;UNESCO & Commonwealth of Learning, 2011).…”
