Global Evolution of Open and Distance Education: From Correspondence to Virtual Learning

Long before internet connections, learning management systems, or virtual classrooms existed, people were already finding ways to learn without stepping into a physical classroom. The story of open and distance education (ODE) is not just about technology – it is about a persistent human drive to make learning accessible to anyone, anywhere. From handwritten postcards exchanged by post in 1840s England to AI-powered online courses today, this evolution spans nearly two centuries and every continent on earth. Understanding this history helps us appreciate how far we have come – and why open education continues to matter more than ever.

Early beginnings: the birth of correspondence education 🔗

The roots of distance education trace back to 1728, when Caleb Philipps advertised shorthand lessons by mail in the Boston Gazette – though this early effort had little documented impact. The real turning point came in 1840 in England. Sir Isaac Pitman, inventor of the Pitman Shorthand system, began mailing texts transcribed into shorthand on postcards to students, who were then asked to transcribe passages and return them for correction. This seemingly simple exchange was revolutionary because it introduced something no teaching method had formally codified before: structured learner feedback at a distance.

What made this scalable was a mundane but critical development – the introduction of uniform penny postage rates across England in 1840, which made sending and receiving course materials affordable. Within three years, the Phonographic Correspondence Society was founded to formalise these courses, eventually paving the way for Sir Isaac Pitman Colleges across Britain. In 1843, Pitman’s shorthand teaching operation had already grown into an organised network – arguably the world’s first correspondence school.

Across the Atlantic, the first formal correspondence school in the United States was founded in 1873 by Anna Eliot Ticknor – the Society to Encourage Studies at Home in Boston – which specifically offered higher education to women, who were largely excluded from universities at the time. This initiative, driven by equity rather than convenience, set an important precedent: distance learning as a tool for inclusion.

Meanwhile, in 1858, the University of London took an even bolder step by establishing its External Programme – the first university in the world to offer degree-level qualifications to students regardless of where they lived. Chartered by Queen Victoria, this programme was called “People’s University” by Charles Dickens for the access it opened to students from less privileged backgrounds.

Growth in Europe and America 🔗

University extension and correspondence schools in America 🔗

By the late 19th century, distance education had moved firmly into mainstream academic life in the United States. William Rainey Harper, the founding president of the University of Chicago, was a vocal advocate for correspondence education. By the 1920s, the University of Chicago, University of Wisconsin, Columbia University, and several dozen other institutions had launched correspondence programmes. The University of Wisconsin went a step further – it is credited as the first institution to formally use the term “distance education” in 1892.

The demand for practical, vocational training also gave rise to large private correspondence schools. The International Correspondence Schools (ICS), based in Scranton, Pennsylvania, was originally founded in 1888 to help immigrant coal miners pass safety examinations. By 1923, ICS served 2.5 million students, offering courses for iron workers, railroad workers, and miners – people who needed education but could not leave their jobs to attend traditional schools. This is an early and striking example of distance education serving the working class.

Germany’s contribution: language learning by post 🔗

Europe was developing its own distance education tradition simultaneously. In 1856, Charles Toussaint and Gustav Langenscheidt established a correspondence school in Berlin for French language instruction – one of the earliest organised distance education programmes in continental Europe. Their “teaching letters” offered practical vocabulary and conversational skills rather than dry grammar – a learner-centred approach that was ahead of its time. When traditional publishers rejected their materials, Langenscheidt founded his own publishing house, which grew into the well-known Langenscheidt language brand still active today.

Germany’s tradition in distance higher education eventually culminated in the establishment of the FernUniversität in Hagen – the country’s only state-funded distance-learning university, and one of Europe’s largest by student numbers. It offered flexible degree programmes in humanities, law, economics, mathematics, and psychology, making it a model for how public universities could operate entirely at a distance.

The UK Open University: a watershed moment 🔗

No discussion of open and distance education history would be complete without the UK Open University (OU). Established by royal charter on 23 April 1969, the OU was the brainchild of Prime Minister Harold Wilson, who envisioned a “University of the Air” that would use broadcasting technology to democratise higher education. The driving force behind its realisation was Jennie Lee, Minister of State for Education, whose humanist conviction that education was a right – not a privilege – shaped the university’s founding philosophy.

The OU was built on an interactive model rather than one-way transmission. Students received printed self-study materials, worked with a personal tutor, attended regional study centres, and participated in residential summer schools. When teaching formally began in January 1971, the first TV programme – Open Forum – was broadcast on BBC2. In its very first year, the OU enrolled 25,000 students. Today, with around 200,000 students, it remains the largest academic institution in the UK by student numbers. Nelson Mandela, famously, studied law at a distance through the University of London’s International Programmes while imprisoned during apartheid – a powerful reminder of what open education can mean in practice.

Technological advancements in distance education 🔗

Radio: the first broadcast classroom 🔗

As the 20th century progressed, each new communication technology was quickly adopted for educational purposes. Radio was the first. By 1938, at least 200 city school systems, 25 state boards of education, and many colleges and universities were broadcasting educational programmes. One of the earliest large-scale radio-based education experiments took place during a 1937 polio outbreak in Chicago, when the city’s entire elementary school system was taught through radio broadcasts for three weeks. In Australia, the famous School of the Air used radio to connect children in the remote outback to their teachers – a lifeline for families living hundreds of kilometres from the nearest school.

Television and multimedia 🔗

Television expanded the reach and richness of distance education further. The University of Houston set up the first educational TV station in 1953. The OU’s partnership with the BBC brought academic programming into British living rooms, normalising the idea that university-level content belonged on public television. Schools also began mailing vinyl records, film strips, and science experiment kits to students – early forms of multimedia learning long before the term existed.

The next leap came with computers. The University of Illinois introduced PLATO (Programmed Logic for Automated Teaching Operations) in 1960 – the first major computer-based education system. It included chat, forums, and interactive lessons – the direct ancestor of today’s learning management systems. By the 1980s, personal computers made it possible to distribute educational software, and the electronics revolution began fundamentally transforming the nature of distance education from print-based delivery to interactive digital learning.

Expansion in developing countries 🔗

Asia: scale and ambition 🔗

As open and distance education matured in Europe and North America, developing regions recognised its immense potential for addressing large, geographically dispersed populations with limited educational infrastructure. In Asia, two institutions stand out for their scale and impact.

In India, Indira Gandhi National Open University (IGNOU) was established in 1985 by an Act of Parliament with a dual mandate: expanding access to higher education and setting standards for open learning across the country. Today, IGNOU is recognised as the world’s largest university, with an enrolment exceeding 3 million students. It operates through 21 Schools of Studies, 67 Regional Centres, and over 2,000 Learner Support Centres, and reaches students in 40 countries. IGNOU uses self-instructional print materials, audio/video programmes, FM radio (Gyan Vani), educational TV channels (Gyan Darshan), tele-conferencing, and online platforms – integrating every layer of communication technology into its teaching model.

In China, the China Central Radio and TV University (now known as the Open University of China) was established in 1979 as the sole distance education provider in the country for over two decades, delivering lectures via TV and radio to millions of students spread across a vast territory. From 1999 onwards, 68 online colleges were authorised by China’s Ministry of Education to offer distance degrees, and since 2014, all Chinese universities have been permitted to offer online programmes.

Africa: overcoming structural barriers 🔗

In Sub-Saharan Africa, open and distance learning emerged as a practical response to severe shortages of physical infrastructure, trained teachers, and public funding for conventional universities. The University of South Africa (UNISA), one of the oldest distance education institutions in the world, became a flagship institution on the continent – providing degree programmes through correspondence and, later, online learning to millions of students in remote areas.

Regional collaboration was a defining feature of African distance education. Botswana, Lesotho, and Swaziland ran a joint university between 1964 and 1975, with a focus on community development through distance programmes. When this institution dissolved, each country continued its own distance education trajectory. Botswana’s subsequent programmes were so effective that, within the first decade of the 21st century, the country had provided approximately 9,000 primary school teachers with a Diploma in Primary Education through distance learning alone.

Russia: distance education at continental scale 🔗

Russia’s vast geography makes it one of the most compelling cases for distance education. Nearly 50% of all higher education students in Russia are enrolled in open or distance education programmes – one of the highest proportions in the world. Radio, television, and eventually the internet have all been deployed to bring university-level education to students in Siberia, the Far East, and other remote regions. Russia’s approach mirrors that of China and India: using broadcast technology and open universities to serve populations that conventional campus-based systems simply cannot reach.

Modern open universities and ICT integration 🔗

The arrival of the internet in the 1990s did not merely add another tool to distance education – it fundamentally redefined what distance learning could look like. IGNOU launched India’s first virtual campus in 1999, beginning with computer and information sciences courses delivered entirely online. Learning Management Systems (LMS), virtual classrooms, and digital libraries began replacing printed study guides as the primary interface between students and their institutions.

The 2000s saw the rise of Massive Open Online Courses (MOOCs), which took the open education philosophy to a global scale. Platforms such as Coursera, edX, and India’s own SWAYAM platform began offering free or low-cost courses from leading universities to anyone with an internet connection. IGNOU now manages 340 MOOCs and operates 7 DTH (direct-to-home) satellite channels, while also running its content through platforms like eGyankosh – a national digital repository of educational materials.

The COVID-19 pandemic of 2020 accelerated this shift dramatically. The percentage of higher education students engaged in some form of distance learning nearly doubled – from 36.9% in 2019 to 74% in 2020. Institutions that had resisted online education for decades were forced to adapt almost overnight, and the infrastructure built over 180 years of open and distance education proved its worth.

Today, the boundaries between open universities and traditional campus-based institutions are blurring. Blended or hybrid learning – combining face-to-face sessions with online delivery – has become standard across the world. Technologies such as video conferencing, AI-driven adaptive learning, interactive simulations, and even virtual reality are being integrated into distance education. The Open University has created its own MOOC platform and actively participates in the Open Educational Resources (OER) movement, offering thousands of free course materials globally. What began as postcards mailed between a teacher and a student has grown into a globally interconnected learning ecosystem.

The trajectory of open and distance education is clear: every century has produced new technologies, and educators have consistently found ways to harness them in the service of access, equity, and lifelong learning. The philosophical core – that geography, income, or circumstance should not determine who gets to learn – has remained constant from Pitman’s penny postcards to today’s AI-enhanced online classrooms.

What do you think? Given that open and distance education has evolved dramatically across different cultural and technological contexts, which phase of this evolution do you think had the most lasting impact on how we understand access to education today? And as virtual learning continues to grow, how should institutions balance the flexibility of online education with the human connection that traditional classrooms offer?
