Terms that might you will encounter during the next few weeks, but that might be unknown to some (these concepts are described really quickly to keep it simple):
Mobile learning: putting it very loosely: it is learning that can happen via a device at any time and/or any place the learner or teacher feels like. This means mLearning can happen inside of the classroom, outside of any training room, individually, amongst a random group (like us), or amongst colleagues/students… From the moment learning is taken out of any time frame and place, it can be seen as mobile. For those who like a more academic definition look at the MobiMOOC definition here.

Mobile devices: any device that is portable (by humans) is a mobile device. This includes basic cell phones or basic mobile phones for banking, sms health alerts, learning), smartphones (a mobile phone with more capacities and most of the time including a Wifi option), netbooks (small laptops), notebooks, laptops, iPods, mp3 players (great for language training), tablet pc’s (including iPads), eBooks, Flip video camera’s (exchanging video’s via social media), … any device that can share media and is portable can be seen as a potential mobile learning device.

Mobile Operating System: smartphones are small computers, as such they use an operating system to interact with the software that is added to the smartphone. It is crucial to know which type of mobile operating system you will be using in your mobile project, as this will define which type of software you will be able to install on your smartphones. If you are unsure on what type of mobile operating systems there are, look at unit 1 of the QR code module.

Mobile tethering: "Tethering" is the use of your cell phone -- or other Internet-enabled mobile device -- as a modem for another device, usually a notebook or PDA. The connection is made either with a cable (USB or serial) or wirelessly through bluetooth (or, in the good old days, via infrared or IrDA). (quoted from About.com)

Ubiquitous learning: is learning which happens across devices and across contexts (Link)

Augmented reality: augmented reality happens when the reality we perceive through our eyes is enlarged by adding information to it. Adding information to our real environment can only happen if we have a camera attached to a screen, as such smartphones are increasingly used to add extra knowledge to our surrounding world, enabling us to access information when it is most relevant. Link for more information.

Learning in the ‘cloud’: this term simply refers to learning online by accessing and sharing resources on the web. Learning is said to be ‘in the cloud’ when it is not linked to one specific place (e.g. gmail is not hosted on your computer, it is hosted on many servers that are always accessible, as such it is like a cloud floating and not attached to one place).

QR codes: a lot of new mobile learning is built around Quick Response codes or QR codes. Augmented reality for instance is sometimes using QR codes to trigger a mobile device to deliver extra information on top of the reality that surrounds us. That is why a basic introduction course to QR codes is provided (if you are new to the concept of QR codes, the course will take you about 1 hour to go through). A QR code is the mobile version of the barcodes you can see on cans in the supermarket. If you want to know more about them look at the short course.

Online learning: is learning through the use of a computer and the Internet.
