Definition The term " open learning " is used to describe learning situations in which learners have the flexibility to choose from a variety of options in relation to the time, place, instructional methods, modes of access, and other factors related to their learning processes. It should be understood from this perspective that a learning situation or process should be open to everyone, under any circumstances, at any place and at any time. In many situations, the term open learning is used interchangeably to refer to e-learning, flexible learning, and distance learning. The term " openness " refers to any teaching organization or institution that offers a variety of choices to learners by giving them the opportunity to study and learn in ways that are independent of time and place. Current approaches to distance learning and e-learning opportunities offer learners a wide range of learning possibilities that take into account learners' limitations and preferences. Learning in this perspective should be perceived as a lifelong process in which learners feel and exercise a wide range of flexibility – especially outside formal learning settings. Theoretical Background There is a significant volume of literature dealing with open and distance learning. Contributions to this area of discourse generally approach the concept from different perspectives. In order to provide a theoretical basis for the concept of open learning, some of its major characteristics will first be outlined. Some of the theoretical perspectives that emphasize the concept from different angles will then be considered. Open learning, distance learning, supported self-study, informal adult learning, home study, e-learning, lifelong learning, and flexible study concepts have been used to describe methods of learning in higher education for the past 40 years. From a learner's perspective, their openness is a common feature, which makes these approaches to educational delivery so attractive. The term " open " came into use as a result of the approaches used by the Open University in the United Kingdom. Indeed, the UK's Open University was the first to be named as open. Open University has since been an example for many other higher education institutions that want to offer open and distance learning courses. These universities or institutions may vary in terms of the extent to which they are " open. " In the field, the term " open education " has evolved into distance learning and later into open and distance learning as a result of developments and trends that require systems to place learners and their needs at the center of teaching and learning processes. Another concept that is used in open
