 Hello and welcome. Do you want to know how teaching, learning and assessment scenarios can be made fit for the 21st century? Do you want to find out what an integrative digital teaching and learning model looks like and what new course formats can be derived from it? Have you ever wanted to produce digital teaching and learning elements but do not know where to start? To answer these questions, this is the perfect open online course for you. The VLC Permanent MOOC Teaching and Learning in the 21st Century. If you have a VLC account, which is of course free, accessing the class is simple. Just log in with your personal data and you will find the class under your personal virtual linguistics campus start site under your current classes on the VLC. A click on the class name leads you to the class start site, where you have access to several class-related links, for example the bibliography, the link section, of course the class description, which is this video and links to the social media, for example, to the Facebook group associated with this class. Furthermore, and this is a novelty in the world of online courses, your class is a PMOOC, a permanent MOOC. But how does it work? Here are the central principles of using a PMOOC on the virtual linguistics campus. Central to our PMOOCs is the idea that you have access to all units of a class at any time. However, if you wish, you can also define your own fixed rhythm using the class timer. Let's say you want to go through the class on a weekly basis, then select the 7 days rhythm. If this is too short for you, go for the 10 days rhythm. If it's too long, select, say, a 4 days rhythm. Please note that the rhythm is just a guideline for you. It marks the unit you should work with in red and makes available the practical solutions in time. Whenever the red marker moves on, you will see these clickable symbols on the practical sheet. But note that, of course, you are free to change your rhythm whenever you like and you can always override it at any time and access any unit of your choice and the components within it. Let us now look at the content of TL21. The class consists of 13 units where the first one, the class preliminaries, informs you about some general aspects of the class and discusses what it means to study online using our PMOOCs. Well, the last one is your option to evaluate the class. The remaining units exhibit the content of this class which is subdivided into four parts. The first part discusses the general principles of learning from traditional to digital. In part two, we will look at assessment again, traditional first, and then the new digital options. The third part focuses on the integration of artificial intelligence methodology and the use of humanoid robots. Not only in terms of future but in terms of existing applications. Part four is practical. We will show you how you can digitize your content and will discuss the role of educational video. The course ends with two options to actively participate. In the unit, the future of TL21, you can deliver your own opinion about what's going to happen in terms of teaching and learning in the future. Well, and in the class evaluation, you can send us your ideas about the class itself. And our teaching and learning concept?
