6  Teaching Support System: Traditional, Modern and ICT based

6.1 The Three Categories

A teaching support system is everything that helps the teacher communicate content to the learner — physical (chalk, model), audio-visual (projector, video) or digital (LMS, virtual lab). The UGC NET syllabus names three categories. Two reliable PYQ patterns: (a) categorise a given item into Traditional / Modern / ICT, and (b) match abbreviation/initiative to full form and coordinator.

TipThree Categories at a Glance
  1. Traditional — chalkboard, textbook, charts, models, real objects, maps, globe, flashcards, flannel-graph.
  2. Modern — OHP, slide projector, audio system, radio, film, TV, language laboratory, video cassette, VCR.
  3. ICT-based — computer, internet, smart board, LMS, MOOC, virtual lab, mobile learning, AI tutors, AR/VR.

6.2 Theoretical Anchors

6.2.1 Dale’s Cone of Experience (1946)

Edgar Dale, in Audio-Visual Methods in Teaching (1946), arranged learning experiences from concrete to abstract: direct purposeful experience → contrived experiences → dramatised → demonstration → field trip → exhibit → television → motion picture → recording-radio-still picture → visual symbols → verbal symbols (most abstract).

Each category of support system maps onto a level of Dale’s cone:

TipMapping Support Systems to Dale’s Cone
Dale’s level Example support
Direct experience Field trip, real-object handling
Contrived experience Working model
Demonstration Live demonstration with apparatus
Television, motion picture Educational TV, film
Recording, radio, still picture AIR broadcast, slide
Visual symbols Chart, diagram, map
Verbal symbols Textbook, lecture

6.2.2 Edgar Dale’s “Three Rs” + the Multisensory Principle

Dale advocated three “Rs” for selecting AV material: Relevance, Reliability, Readability. Modern teachers add Reusability and Reach. Underlying principle: the more senses engaged, the better retention — known as multisensory learning.

6.2.3 Bruner’s EIS Model (1966)

Jerome Bruner (1966, Toward a Theory of Instruction) proposed three modes of representation, used in this order from concrete to abstract:

TipBruner’s EIS Modes
  • E — Enactive (action-based) — using real objects, manipulatives.
  • I — Iconic (image-based) — diagrams, photographs, charts.
  • S — Symbolic (language/abstract) — words, equations, formulas.

Traditional supports (real objects, chart) cover enactive + iconic; ICT supports (animation, simulation) span all three.

6.2.4 Mayer’s Cognitive Theory of Multimedia Learning (2001)

Richard E. Mayer (2001) proposed the CTML for designing ICT support: humans process information through dual channels (visual + auditory) of limited capacity, requiring active processing. From CTML come the 12 principles of multimedia design — including multimedia, contiguity (spatial & temporal), coherence, signalling, redundancy, segmenting, modality, personalisation, voice and image principles. Practical takeaway: a slide with diagram + narration (dual channel) outperforms the same slide with diagram + on-screen text + narration (redundant).

6.3 Traditional Support Systems

6.3.1 The Chalkboard / Blackboard

Still ubiquitous, especially in mathematics and engineering. Strengths: infinitely re-writable, supports the unfolding of an argument (essential in mathematics proofs), zero technological dependency, allows learner pace-matching. Effective use principles: top-down structure, legible from the back row (lettering size ≈ 5 cm for 10 m room), use colour for emphasis, leave margin for re-entry, erase only after recording.

6.3.2 The Textbook

Print remains the most economical and most portable support. The textbook supports deep, sustained, non-linear engagement — re-reading, marginal notes, indexing. Good textbook criteria: alignment with curriculum, accuracy, language level, illustrations, exercises, glossary, index, recency.

6.3.3 Charts, Diagrams, Maps, Globe

Static visual supports that turn complex relationships into a single scannable image — for example, a phylogenetic tree or political map. Effective use: hang at eye level, use minimal text, refer-to-and-name during teaching.

6.3.4 Models — Working and Static

TipThree Types of Model
  • Solid / Scale model — globe, anatomical model.
  • Cross-section / Cut-away model — internal-combustion engine cut-away.
  • Working model — DC motor, hydraulic cycle demonstrator.

6.3.5 Real Objects (Realia) and Specimens

Real samples from the world — a rock specimen, a leaf, a coin, a piece of textile. The most concrete support; mandatory in laboratory sciences.

6.3.6 Other Traditional Supports

Flashcards (drill, vocabulary), flannelgraph and felt board (story-telling, primary), picture cards, bulletin board (current display), dioramas (3-D scene).

6.4 Modern Support Systems

“Modern” in the UGC syllabus refers to the 20th-century audio-visual family — pre-internet but more advanced than traditional.

6.4.1 Overhead Projector (OHP)

Projects transparencies (Cellotape acetates) onto a screen. Strengths: teacher faces the class, can write on transparency live, layering via overlays. Still useful where electricity is unreliable but bulb-and-glass projector available.

6.4.2 Slide Projector and Filmstrip

Still images projected sequentially. Replaced by digital projector. Useful for art history, geography.

6.4.3 Educational Radio and Audio System

TipIndian Educational Radio Initiatives
  • AIR (All India Radio) — educational broadcasts since 1937.
  • Gyan Vani — dedicated educational FM network of IGNOU/MoE (2001 onwards) across 40+ stations.
  • Gyan Dhara — internet audio streaming of IGNOU programmes.

6.4.4 Educational Television

TipIndian Educational TV Initiatives
  • CCTV in classrooms — Delhi schools, 1961.
  • SITE (Satellite Instructional Television Experiment) — 1975–76, ISRO+UNDP+UNESCO, telecast to 2,400 villages using ATS-6 satellite — landmark in Indian distance education.
  • INSAT-1B + UGC’s Countrywide Classroom — 1984; later moved to Doordarshan.
  • Gyan Darshan — educational TV channel (2000) by IGNOU + MoE; replaced by SWAYAM Prabha.
  • SWAYAM Prabha (2017) — 32+ DTH educational channels, 24×7, GSAT-15, INFLIBNET coordinator.
  • EMRC / EMMRC (Educational Multimedia Research Centres) — content production for CEC.

6.4.5 Language Laboratory

A room with audio cabins where learners listen to native-speaker recordings and record themselves. Three generations: (1) conventional analog (open-reel/cassette), (2) digital (PC + headphones + software), (3) multimedia + AI (speech recognition, accent feedback).

6.4.6 Video Cassette / DVD / VCR

Now historical, but PYQ-relevant for matching against the timeline (pre-internet AV).

6.5 ICT-Based Support Systems

6.5.1 Defining ICT in Education

ICT = Information and Communication Technology — the convergence of computing, telecom, broadcasting, and content. UNESCO defines ICT in education as “the diverse set of technological tools and resources used to communicate, create, disseminate, store, and manage information.”

6.5.2 Hardware Backbone

TipHardware that Enables ICT Support
  • Computer / laptop / tablet / smartphone
  • Smart class hardware — interactive whiteboard (Smart Board), digital pen, document camera (visualiser), short-throw projector
  • Networking — LAN, Wi-Fi, fibre, 4G/5G
  • Servers / cloud
  • Peripherals — printer, scanner, webcam, microphone, speakers
  • Storage — HDD, SSD, USB, cloud (Google Drive, OneDrive)

6.5.3 Software Backbone

TipSoftware that Powers ICT Support
  • Productivity — word processor, spreadsheet, presentation, mind-map.
  • LMS — Moodle, Sakai, Blackboard, Canvas, Google Classroom, MS Teams.
  • Authoring — Adobe Captivate, Articulate Storyline, H5P.
  • Synchronous comms — Zoom, Google Meet, MS Teams, Cisco Webex.
  • Repositories — institutional repository on DSpace/EPrints.
  • Reference managers — Mendeley, Zotero, EndNote.

6.5.4 Learning Management System (LMS)

A Learning Management System organises content delivery, communication, assessment, and tracking in one platform. Six core functions of an LMS:

TipCore Functions of an LMS
  1. Content delivery — text, video, slides, SCORM packages.
  2. Enrolment & user management — students, teachers, roles.
  3. Communication — announcement, forum, chat, email.
  4. Assessment — quiz, assignment, rubric, peer-review.
  5. Tracking & analytics — progress, completion, time on task.
  6. Credentialing — certificates, badges, grade book.

Major LMS platforms: Moodle (FOSS, India’s default in HEIs), Blackboard, Canvas, Brightspace, Sakai, Google Classroom, MS Teams for Education.

6.5.5 Smart Classrooms and Smart Boards

A smart classroom integrates interactive whiteboard + projector + computer + audio + internet, often with document camera (visualiser) and student response system (clickers). NEP-2020 + Samagra Shiksha + RUSA fund smart-classroom expansion.

6.5.6 Virtual Laboratory

A simulated laboratory that lets the learner perform experiments in a browser or app. India’s Virtual Labs initiative (NMEICT, MoE, lead by IIT Delhi) hosts virtual labs across 12 disciplines — physics, chemistry, biotechnology, electronics, mechanical, civil, computer science, chemical engineering, biomedical, electrical, and more.

6.5.7 Mobile Learning (M-learning)

Learning delivered via smartphone or tablet — most learners’ first device. Strengths: ubiquity, low cost, microlearning capability, offline support. DIKSHA app (school) and SWAYAM mobile app (HE) are flagship Indian m-learning examples.

6.5.8 Open Educational Resources (OER) and Creative Commons

OER are teaching, learning, or research materials in the public domain or released under an open licence — chiefly Creative Commons (CC). The 6 CC licences:

TipThe Six Creative Commons Licences
Licence What it allows
CC BY Share & adapt with attribution
CC BY-SA Same as BY, derivative must use same licence
CC BY-ND Share with attribution; no derivatives
CC BY-NC Share & adapt; non-commercial only
CC BY-NC-SA Non-commercial + share-alike
CC BY-NC-ND Most restrictive — share for non-commercial, no derivatives

The 2002 UNESCO Forum on Open Courseware popularised the term OER; MIT OpenCourseWare (2001) was the first large-scale OER initiative.

6.5.9 Augmented, Virtual & Mixed Reality (AR/VR/MR), AI and Adaptive Learning

TipFrontier ICT Support Modalities
  • AR (Augmented Reality) — overlays digital content on the real world (e.g., anatomy AR app over a textbook page).
  • VR (Virtual Reality) — fully immersive 3-D simulation (e.g., surgical training VR).
  • MR (Mixed Reality) — hybrid; e.g., Microsoft HoloLens.
  • AI tutors / Intelligent Tutoring Systems (ITS) — personalised pace and feedback (e.g., Carnegie Cognitive Tutor, Squirrel AI).
  • Adaptive learning — algorithmic content adjustment by performance (Knewton, ALEKS).
  • Generative AI in education — ChatGPT, Khanmigo (Khan Academy + GPT-4).

6.7 Selecting the Right Support — A Decision Framework

A teacher’s everyday decision is which support to use, when, for what objective.

TipSeven Filters for Support-System Choice
  1. Learning objective — Bloom level, type of knowledge.
  2. Learner profile — age, prior knowledge, digital readiness.
  3. Content nature — abstract concept, procedure, attitude.
  4. Class size — large → projection/MOOC; small → handout/discussion.
  5. Available infrastructure — bandwidth, electricity, devices.
  6. Cost & equity — per-learner cost, accessibility.
  7. Time — preparation time, contact-hour budget.

The ASSURE model is a six-step instructional-design framework specifically for selecting and using support media (Heinich, Molenda, Russell, Smaldino — 1980s):

TipASSURE Model — Heinich et al.
  • A — Analyse learners
  • S — State objectives
  • S — Select strategies, technology, media, materials
  • U — Utilise technology, media, materials
  • R — Require learner participation
  • E — Evaluate & revise

6.8 Equity, Access and the Digital Divide

ICT-based supports are not neutral — they amplify the inequalities of the surrounding infrastructure.

TipThe Three Levels of the Digital Divide
  1. Access divide — who has the device + connection.
  2. Skills divide — who can use them effectively.
  3. Outcome divide — who actually benefits in learning outcomes.

Indian responses: SWAYAM Prabha for non-internet learners; DIKSHA’s offline content; PM eVidya 12+12 TV channels; subsidised data plans; community technology centres. RPwD Act 2016 mandates accessibility for ICT — screen readers, captions, alternative formats.

6.9 Effectiveness — What the Evidence Says

TipFive Robust Findings from Meta-Analyses
  1. Multimedia outperforms text-only when designed per Mayer’s principles, not otherwise.
  2. Blended learning outperforms either pure face-to-face or pure online (US Dept of Education meta-analysis, 2010).
  3. Drill software boosts low-Bloom outcomes; simulations and PBL platforms boost high-Bloom outcomes.
  4. Teacher mediation is the single biggest predictor of ICT effectiveness — equipment alone produces little.
  5. Equity gains depend on closing the access divide first.
