Delivery systems conveying teaching and learning activities can include distance or online learning, face-to-face learning in a formal or informal setting, or blended/hybrid learning, which is a combination of both. The rapid changes in technology as well as the expectations of younger learners to be able to learn anywhere with constant, reliable access to materials and information online, force learning institutions and workplaces to adapt. Issues such as equity and access are also important to consider. These trends evolve quickly with new challenges in delivering learning constantly arising. For example, mobile and online learning are different today to what they were yesterday with the introduction of virtual reality, social media and apps providing opportunities and challenges for the teaching and learning field.
