The term m-learning ("mobile learning"), has different meanings for different communities, covering a range of use scenarios including e-learning, educational technology and distance education, that focuses on learning with mobile devices. Mobile learning is defined as "learning across multiple contexts, through social and content interactions, using personal electronic devices”  (Crompton, 2013 p. 4) In other words, with the use of mobile devices, learners can learn anywhere and at any time.
M-learning technologies include handheld computers, MP3 players, notebooks, mobile phones and tablets. M-learning focuses on the mobility of the learner, interacting with portable technologies, and learning that reflects a focus on how society and its institutions can accommodate and support an increasingly mobile population. There is also a new direction in m-learning that gives the instructor more mobility and includes creation of on the spot and in the field learning material that predominately uses smartphone with special software such as AHG Cloud Note. Using mobile tools for creating learning aids and materials becomes an important part of informal learning.
M-learning is convenient in that it is accessible from virtually anywhere. M-learning, like other forms of e-learning, is also collaborative. Sharing is almost instantaneous among everyone using the same content, which leads to the reception of instant feedback and tips. This highly active process has proven to increase exam scores from the fiftieth to the seventieth percentile, and cut the dropout rate in technical fields by 22 percent. M-learning also brings strong portability by replacing books and notes with small devices, filled with tailored learning contents. In addition, it is simple to utilize mobile learning for a more effective and entertaining experience.

Arguably the first instance of mobile learning goes back as far as 1901 when Linguaphone released a series of language lessons on wax cylinders. This was followed up in later years as technology improved, to cover compact cassette tapes, 8 track tape, and CDs[dubious ]
In 1968 Alan Kay and his colleagues in the Learning Research Group at Xerox Palo Alto Research Center [PARC] propose the Dynabook as a book-sized computer to run dynamic simulations for learning. "The Dynabook would carry an encyclopedia of information inside its circuits and plug into readily available networks containing the sum of human knowledge. Anybody from grade school up would be able to program it to do whatever was wanted. And there's no reason it would even have to be a book; it could just as well be a wristwatch, or woven into a T-shirt."
In May 1991, Apple Classrooms of Tomorrow (ACOT) in partnership with Orange Grove Middle School of Tucson, Arizona, used mobile computers connected by wireless networks for the 'Wireless Coyote' project. Universities in Europe and Asia developed and evaluated mobile learning for students. Palm corporation offered grants to universities and companies who created and tested the use of Mobile Learning on the Palm OS platform. Knowledgility created the first mobile learning modules for CCNA, A+ and MCSE certification using the core tools that later became LMA.
The European Commission began to fund the major multi-national MOBIlearn and M-learning projects.
Companies, specializing in these three core areas of mobile learning were formed.
- Authoring and Publishing
- Delivery and Tracking
- Content Development
Conferences and trade shows were created to specifically deal with mobile learning and handheld education, including: mLearn, WMUTE, and IADIS Mobile Learning international conference series, ICML in Jordan, Mobile Learning in Malaysia, Handheld Learning in London, and SALT Mobile in USA. In 2003, "Hello China" pioneered the use of mobile phones for large scale training by sending words to learn to the mobile phones of participants throughout China.
By mid-2000's mobile learning started moving beyond school and into the workplace. Vocational colleges in the UK (FE) sent trainees into the workplace armed with PDAs (the precursor to smartphones), and companies themselves began offering mobile learning and performance support to employees. In 2007 the MoleNET initiative in the UK was allocated £6m of funds which went to 30 FE colleges, to support mobile vocational, and at-work training. Further funding followed over the next 3 years, consolidating the role of mobile in "beyond school" learning.
2010 and beyond
As a large number of smart mobile devices came onto the market, m-learning developers faced a decision as to which devices (smartphone or tablet) and operating systems they would target.
Apple, Android and Blackberry were, for several years during this decade, the three most popular operating systems. Blackberry OS is enduring a diminishing prominence. Clearly, the Apple iOS and Android operating systems are premier and attract the most activity among both developers and users. Multi-device learning design is becoming increasingly important as learning designers set out to design once and deliver to all three operating systems as well as a variety of device sizes.
2011 and 2012 saw the increasing availability of multi-device authoring tools such as Captivate, Articulate Storyline, Lectora and GoMoLearning. These tools allow e-learning courses to be delivered to a variety of mobile operating systems and devices as well as to PCs, although not all tools output to all operating systems and devices.

Over the past ten years mobile learning has grown from a minor research interest to a set of significant projects in schools, workplaces, museums, cities and rural areas around the world. The m-learning community is still fragmented, with different national perspectives, differences between academia and industry, and between the school, higher education and lifelong learning sectors.
Current areas of growth include:
- Testing, surveys, job aids and just-in-time (J.I.T.) learning
- Location-based and contextual learning
- Social-networked mobile learning
- Mobile educational gaming
- Delivering m-Learning to cellular phones using two way SMS messaging and voice-based CellCasting (podcasting to phones with interactive assessments) 
- Cloud computer file storage 
According to a report by Ambient Insight in 2008, "the US market for Mobile Learning products and services is growing at a five-year compound annual growth rate (CAGR) of 21.7% and revenues reached $538 million in 2007. The data indicates that the demand is relatively immune from the recession." The findings of the report indicate that the largest demand throughout the forecast period is for custom development services, content conversion, and media services and that the healthcare sector accounts for 20% of the total US market for mobile learning.
Technologies currently being researched for mobile learning include:
- Location aware learning
- Point-and-shoot learning with camera phones and 2D codes
- Near Field Communications (NFC) secure transactions
- Sensors and accelerometers in mobile devices in behavioral based learning
- Mobile content creation (including user generated content)
- Games and simulation for learning on mobile devices
- Context-aware ubiquitous learning
- Augmented reality on mobile devices
- Mobile performance support
While many think of mobile learning as delivering E-Learning on small form factor devices, or often referred to as E-Learning “lite”, it has the potential to do much more than deliver courses, or parts of courses. It includes the use of mobile/handheld devices to perform any of the following:
- Deliver education materials and promote learning
- Faster communications and collaboration
- Conduct assessments and evaluations
- Provide access to performance support and knowledge
- Capture evidence of learning activity
Today, any number of portable devices can quickly and easily deliver and support these functions. Cell phones or smartphones, multi-game devices, personal media players (PMPs), personal digital assistants (PDAs), and wireless single-purpose devices can help deliver coaching and mentoring, conduct assessments and evaluations (e.g., quizzes; tests; surveys and polls; and certifications), provide on-the-job support and access to information, education and references, and deliver podcasts, update alerts, forms and checklists. In these ways, mobile learning can enhance and support more traditional learning modes, making it more portable and accessible. Mobile devices can also serve as powerful data collection tools and facilitate the capture of user created content.
New mobile technology, such as hand-held cellular based devices, is playing a large role in redefining how we receive information. The recent advances in mobile technology are changing the primary purpose of mobile devices from making or receiving calls to retrieving the latest information on any subject. "Numerous agencies including the Department of Defense (DoD), Department of Homeland Security (DHS), Intelligence community, and law enforcement are utilizing mobile technology are utilizing mobile technology for information management." 
- Class management
Mobile devices(such as a Pocket PC) in the classroom can be used to enhance group collaboration among students through communication applications, interactive displays, and video features.
- Existing mobile technology can replace cumbersome resources such as textbooks, visual aids, and presentation technology.
- Interactive and multi-mode technology allows students to engage and manipulate information.
- Mobile Device features with WIFI capabilities allow for on-demand access to information.
- Access to classroom activities and information on mobile devices provides a continuum for learning inside and outside the classroom.
In an experiment to make learning mobile through the use of tablet computers, 32% of 8th grade students at Stone Middle School found that they were more engaged in the classroom and had a better understanding of course material. In a literature review conducted by FutureLab, researchers found that increased communication, collaboration, and understanding of concepts was a result of mobile technology applications.
Blended learning combines brick-and-mortar schooling with online delivery of content and instruction. Mobile devices provide support that enhances teaching and learning in a virtual classroom environment.
- Class management
Mobile devices are used both in the brick-and-mortar setting as well as in the online setting to enhance the education experience.
- The mobile phone (through text SMS notices) can be used especially for distance education or with students whose courses require them to be highly mobile and in particular to communicate information regarding availability of assignment results, venue changes and cancellations, etc. It can also be of value to business people, e.g. sales representatives who do not wish to waste time away from their busy schedules to attend formal training events.
- Mobile devices facilitate online interaction between instructor and student, and student to student.
- Blended learning takes the classroom out of a traditional brick-and-mortar setting. Students become part of virtual communities used for collaboration. Blended learning transitions away from a traditional teaching environment to a customized and interactive web platform for the user 
Podcasting consists of listening to audio recordings of lectures. It can be used to review live lectures (Clark & Westcott 2007) and to provide opportunities for students to rehearse oral presentations. Podcasts may also provide supplemental information to enhance traditional lectures (McGarr 2009) (Steven & Teasley 2009).
Psychological research suggests that university students who download podcast lectures achieve substantially higher exam results than those who attend the lecture in person (only in cases in which students take notes) (Callaway & Ewen 2009).
- Learning in museums or galleries with handheld or wearable technologies
- Learning outdoors (e.g. On field trips).
- Continuous learning and portable tools for military personnel.
M-learning in a work place can be very different from a schools context. Although employees do occasionally attend face to face training events, the majority of work based learning happens on the job, often at the moment of need. Because of this, m-learning is being used in a wider range of modes:
- On the job training for someone who accesses training on a mobile device.
- Just in time training to solve a problem or gain an update.
- Performance support. Immediate access to tools to streamline a work-task
- Reference guides and ebooks
Due to the very diverse training needs across a large organisation, self-serve learning is more comon than is found at the school, or college level. Mobile is seen as an effective way to reach a large number of employees easier and more effectively.
Lifelong learning and self-learning
The use of personal technology to support informal or lifelong learning, such as using handheld dictionaries and other devices for language learning, is an approach that is not to be overlooked.
Mobile technologies and approaches, i.e. Mobile Assisted Language Learning (MALL), are also used to assist in language learning. For instance handheld computers, cell phones, and podcasting (Horkoff Kayes2008) have been used to help people acquire and develop language skills.
- Improving levels of literacy, numeracy, and participation in education amongst young adults.
- Using the communication features of a mobile phone as part of a larger learning activity, e.g.: sending media or texts into a central portfolio, or exporting audio files from a learning platform to your phone.
- Developing workforce skills and readiness among youth and young adults.
Mobile devices and personal technologies that can support mobile learning, include:
- Smartphone, an aggregator of most of the following technologies
- Handheld audio and multimedia guides, in museums and galleries
- Handheld game console, modern gaming consoles such as Sony PSP or Nintendo DS
- Personal audio player, e.g. for listening to audio recordings of lectures (podcasting)
- Personal Digital Assistant, in the classroom and outdoors
- Tablet computer
- UMPC, mobile phone, camera phone and SmartPhone
