Programmed Instruction (PI) — concept for creating content that enables self-learning

Also called Auto-Instruction — learner teaches themselves

Content organized based on individual learner's level

Useful for self-learning & applicable in any classroom

Innovative new approach to teaching-learning

Related field: Instructional Design

Applicable where: practical involvement + systematic logical study

Two types: Linear Programming & Branching Programming

1920s — Sidney Pressey (Psychology Professor) built a Teaching Machine

Machine: device where you click options — correct → next question; wrong → re-attempt

Teaching machine became very popular

B.F. Skinner started working on it; coined the actual term

Skinner presented paper: "The Science of Learning and the Art of Teaching"

Presented at: Conference of Current Trends in Psychology, Univ. of Pittsburgh, March 12, 1954

1953 — Skinner visited his daughter's school; observed: instruction not systematic, children studying to avoid punishment, reward system inconsistent/irregular

He concluded: instructions must be presented more systematically

Principle of Sequential & Small Steps — content broken into tiny, logical steps

Principle of Active Response — learner actively responds at every frame

Principle of Immediate Feedback — instant knowledge of correctness

Principle of Self-Pacing — learner progresses at own speed

Principle of Reinforcement — suitable reward for correct responses; motivation

Punishment can also be used for motivation to re-learn

Based on: humans learn best in step-wise manner with reinforcement

Content organized in frames — single sequential path

All learners follow the same path — no deviation

Each frame: instruction → response → feedback

Correct → move to next frame; Incorrect → retry same frame

Cannot proceed until current frame is cleared

Reinforcement (reward) → motivated to learn more

Even incorrect → motivated to re-study & re-attempt

Frames = small units of content: Frame 1, Frame 2, Frame 3... each with different instruction

Example: Cell cycle topic → Frame 1: Cell basics, Frame 2: Cell types, Frame 3: Phases, Frame 4: Problems if cycle fails (cancer, disease)

Linear — single path, all learners same route, cannot skip frames

Branching — multiple paths; can explore related content from a frame; connect interlinked topics

Branching: allows connecting related concepts from a frame

Both used for self-instruction

Step 1: Identify Learning Objectives — what should students achieve? (e.g., plant physiology, animal physiology, diversity)

Step 2: Content Analysis — break big units into chapters; break chapters into sub-topics for easy instruction

Step 3: Sequence Content — simple → complex; step by step progression; each unit focuses on a specific concept

Step 4: Design Written Materials — clear, concise, comprehensive; easy language; age-appropriate; examples included

Step 5: Add Interactive Elements — videos, games, animations; enhances engagement

Step 6: Practice Exercises — at end of each frame; allows practice before moving on

Step 7: Real-World Applications — include how content applies in real life

Step 8: LMS Integration — use Learning Management Systems (Moodle, Blackboard, apps) to present meaningfully

Step 9: Self-Assessment & Reflection — student can self-assess; reflection on what/how learned; what to improve

Step 10: Support & Resources — teacher provides time-to-time support; additional resources: textbooks, articles, research papers, review papers, external links

Develops independence — child learns on their own

Self-paced — according to child's own speed & ability

Content tailored to individual interests & curiosity

Builds self-learning ability (self-instruction)

All experiences provided through content so biology becomes easy

Language must be age-appropriate — if not understood, child won't learn

Reflection — self-assess: how did I learn? Where can I improve? Future mistakes to avoid

Written materials must be clear, concise, comprehensive; easy language; appropriate for target age

Frame content = same content logically broken down, NOT a puzzle

Teacher must provide ongoing scaffolding & support

Design materials based on learner's prior knowledge & level

Include examples from student's own subject (if different pedagogy subject, adapt examples)
