What is learning?

• Learning takes place when a person is in the process of acquiring knowledge.

• Knowledge is acquired through interaction between the individual and the environment.

What is ubiquitous learning?

• It is an expansion of previous learning paradigms

• U-learning is anywhere and anytime learning.

• U-learning includes any environment that allows any mobile device to access learning and teaching contents via wireless networks in any location at anytime.

• RFiD’s (radio-frequency identification), contactless smart cards, sensor networks and mobile devices are part of ubiquitous computing technologies.

• Proposed definition of u-learning: U-learning is a learning paradigm which takes place in an ubiquitous environment that enables learning the right thing at the right time in the right way.

Learning environments

• Computing and communication technologies are key components of ubiquitous learning.

• The communication technologies include:

• Radio-frequency identification

• Mobile phones

• Wireless communication equipment

• Personal digital assistants (PDAs)

• Wearable computers: Wearable computers, also known as body-borne computers or wearables are miniature electronic devices that are worn by the bearer under, with or on top of clothing.[

Computing and communication technologies

Characteristics of ubiquitous learning

• Adaptability: Learners get right information in the right places, time and way.

• Permanency: Learners never lose work. All the learning processes are recorded continuously.

• Accessibility: Learners Have access to documents, data, video from anywhere.

• Immediacy: Learners can get information wherever learners are.

• Interactivity: Learners can interact with experts, teachers, peers in the form of synchronous and asynchronous communication.

• Situating of instructional activities: Knowledge required are presented in their natural and authentic forms.

Context and ubiquitous learning

• Context is the location, identity and state of people, groups and computational and physical objects.

• Three types of information needed to describe any specific context are: places, people and things.

• Four aspects are needed to describe places, people and things:

• Identity: It characterizes the entity with an explicit identifier which has to be unique in the name domain of the application.

• Location: Includes position, data and orientation as well as information about relations to other entities.

• Status: Contains properties which can be perceived by a user.

• Time: Is both date and time.

Sensors and ubiquitous learning

• A device that receives physical stimulus, converts it into a signal which can be used by other instruments.

• There are various sensors available, namely:

• Location sensors: GPS receives this information to calculate specific location.

• User oriented sensors: Built-in digital compass works like a magnetic needle.

• Touch sensors: Used to recognize a person's touch.

• Light/dark sensors: Allowing for adjustment of screen’s background.

• Device orientation and motion sensors: Motion sensors detect acceleration forces.

• Proximity sensors: Detect objects without physical contact. Emits electromagnetic field and look for changes in the field.
