Extension Management I: History and Philosophy of Extension, Programme Management, Extension Methods and Audio-Visual Aids, Curriculum Development and Bloom's Taxonomy, and Non-Formal, Adult and Lifelong Education

An extension programme is managed as a cycle. Needs assessment identifies the gap between what is and what should be; Jonathan Bradshaw's typology (1972) distinguishes normative needs (defined by experts against a standard), felt needs (what people say they want), expressed needs (felt needs turned into demand) and comparative needs (inferred from what similar groups receive). Situation analysis collects facts on the people, resources, problems and institutions, often summarised as strengths, weaknesses, opportunities and threats. Planning sets priorities, specific and measurable objectives, activities, responsibilities, a time schedule and a budget, often in a logical framework (goal, purpose, outputs, activities, with indicators, means of verification and assumptions). Organisation arranges staff, materials and partners; implementation carries the plan out with the people.

Two group methods are often confused. A method demonstration shows how to do something, step by step, with the audience practising (preparing ORS, making a low-cost weaning food); it teaches a skill in a single session. A result demonstration shows what a practice achieves by comparing its result with the usual practice over time (a kitchen garden beside a bare plot, a fortified feeding trial); it convinces people that the practice is worth adopting. Audio-visual aids help people attend, understand, remember and act, and overcome barriers of language and literacy. They are classified as audio (radio, recordings), visual (projected: slides, transparencies, presentations; non-projected: charts, posters, flash cards, flannelgraphs, models, specimens, photographs, bulletin boards) and audio-visual (films, video, television). Edgar Dale's Cone of Experience (1946) ranks experiences from direct, purposeful experience at the broad base, through contrived and dramatised experiences, demonstrations, field trips, exhibits and motion pictures, to visual and verbal symbols at the narrow top: the more concrete the experience, the easier the learning for most rural audiences.

• Planning an aid: define the objective, know the audience (age, literacy, language, culture), select one main message, and choose the aid that fits the method and setting.
• Preparation: simple, bold and uncluttered design, local images and colours, large legible text in the local language.
• Field-testing (pretesting) with a small sample of the intended audience checks attraction, comprehension, acceptability, self-involvement and persuasion before mass production.
• Use and evaluation: introduce the aid at the right moment, keep it visible, involve the audience, then judge whether it achieved its objective and revise.

Curriculum development for extension follows the logic Ralph Tyler set out in 1949 as four questions: what purposes should the programme seek; what learning experiences will attain them; how can they be organised effectively; and how can we determine whether the purposes are being attained? In practice this means analysing the learners' situation and needs, stating objectives in terms of behaviour, selecting and sequencing content, choosing methods and materials, and building in evaluation. J. P. Leagans described the teaching-learning situation as five elements, the instructor, the learners, the subject matter, the teaching materials and the physical facilities, all of which must be in place for learning to occur.

Two further domains complete the taxonomy. The affective domain (Krathwohl, Bloom and Masia, 1964) runs receiving, responding, valuing, organisation and characterisation by a value or value complex; it matters in extension because adoption depends on attitudes and values, not knowledge alone. The psychomotor domain, classified by Simpson (1972) and by Dave and Harrow, covers skills from perception and guided response to adaptation and origination, the domain of method demonstrations.

Philip Coombs and Manzoor Ahmed (1974) distinguished formal education (the graded, hierarchical school and university system), non-formal education (organised educational activity outside the formal system for identifiable learners and objectives, such as literacy classes or farmers' training) and informal education (lifelong learning from daily experience, family, work and media). Lifelong learning was put at the centre of educational policy by UNESCO's Faure report, Learning to Be (1972), and the Delors report, Learning: The Treasure Within (1996), with its four pillars: learning to know, to do, to live together and to be.

India's adult education history runs from social education after independence to the National Adult Education Programme (1978), the National Literacy Mission (1988) with its campaign-based total literacy campaigns, Saakshar Bharat (2009) with its focus on women, and the New India Literacy Programme, ULLAS (2022-27), for non-literate adults aged 15 and above, covering foundational literacy and numeracy, critical life skills, basic education, vocational skills and continuing education. Approaches include centre-based classes, mass campaigns, each-one-teach-one volunteering, and open and distance learning. Challenges include learner motivation and dropout, relapse into illiteracy without post-literacy materials, volunteer fatigue, gender and caste barriers, and evaluating learning outcomes rather than enrolment.
