A good teacher does not just talk through a chapter. They get your attention, tell you what you will be able to do by the end, connect it to what you already know, show an example, let you try, and correct you. When you study alone, most of those steps vanish, and you are left reading. Robert Gagne spent his career working out which steps a lesson needs. This post introduces him, lists his nine events of instruction, and turns them into a one-hour self-study plan.
Who was Robert Gagne?
The Association for Psychological Science's appreciation of Robert Mills Gagne records that he took his bachelor's degree at Yale in 1937 and his PhD at Brown in 1940, and died on 28 April 2002 in Signal Mountain, Tennessee. During the Second World War he was drafted into the Army Air Corps, where he worked on tests for classifying air crew. He later moved to Florida State University, which had a strong focus on instructional science, and stayed until he retired in 1986. As a high school student in 1932, he said in his valedictory speech that psychology should be used to relieve the burdens of human life.
His best-known book, The Conditions of Learning, was first published in 1965 according to its Open Library record, and went through several editions. His idea that there are distinct varieties of learning became standard enough that Lee Shulman, in a 1986 paper on teacher knowledge, listed "Gagné's varieties of learning" among the established ways of describing content knowledge.
What are the nine events of instruction?
Northern Illinois University's teaching centre gives the nine events, adapted from Gagne, Briggs and Wager's Principles of Instructional Design, and describes them as associated with the mental conditions for learning:
Gain attention.
Inform learners of the objectives.
Stimulate recall of prior learning.
Present the content.
Provide learning guidance.
Elicit performance (practice).
Provide feedback.
Assess performance.
Enhance retention and transfer.
The events were written for people designing lessons. The useful trick is to see that a student studying alone can play both roles.
How do you run the nine events on yourself?
Here is a 60-minute session for one topic, using the Class 11 topic of projectile motion as the example.
Gain attention (2 minutes). Start with a puzzle, not a page. "If I drop one ball and throw another sideways from the same height, which lands first?" Write your guess.
State the objective (1 minute). Write one line: "By the end I can find the range, time of flight and maximum height of a projectile, and explain why horizontal and vertical motion are independent."
Recall what you know (5 minutes). Without notes, write the equations of motion and how to split a vector into components. Gaps here explain most later errors. Our profile of David Ausubel and prior knowledge explains why this step matters.
Present the content (10 minutes). Read the textbook section or watch one short explanation. Only one source.
Get guidance (10 minutes). Study one worked example and say why each step follows. This is where you see the method used.
Practise (15 minutes). Solve three problems with the book closed. Make one of them slightly different, such as a launch from a height.
Get feedback (5 minutes). Check each answer and, for every error, write what kind it was: concept, set-up or arithmetic.
Assess yourself (7 minutes). One fresh problem, timed, no help. This tells you whether the session worked.
Plan retention and transfer (5 minutes). Put the topic on your revision calendar for two days and a week later, and note one problem from another chapter where the same idea appears, such as a charged particle in a uniform electric field.
What does research say about the practice and feedback steps?
Events 6 and 8 are retrieval, and retrieval does more than measure learning. In Roediger and Karpicke (2006), students either restudied prose passages or took free-recall tests on them. On a test five minutes later, restudying did better. On tests two days and one week later, the students who had been tested remembered substantially more, even though restudying made students more confident.
Event 7 needs care. Hattie and Timperley (2007) reviewed the evidence on feedback and concluded that it is one of the major influences on learning, but that its effect can be positive or negative depending on the type of feedback and how it is given. Marking an answer only right or wrong tells you little. Writing which step went wrong and why tells you what to change.
What can a student take from how he worked?
Break a big goal into conditions. Gagne asked what has to be true for learning to happen, then listed it. You can do the same for any topic that is not sticking.
Know which kind of learning you need. Memorising the value of g, applying a formula and solving an unfamiliar problem are different tasks that need different practice.
Design for transfer, not just recall. The last event asks where else the idea applies. Exams reward exactly that.
Steps 3 and 5 are hardest alone, because you need to know what you have forgotten and you need a good example. Fermi's AI tutor works out what a student knows and builds a plan for the session, which covers the planning part; the practice still has to be yours. For timing the retention step, see our guide to a spaced revision schedule.
Pick one topic for tomorrow and write the nine lines of your session plan tonight.
