True or False? Teachers teach students by motivating them to learn, then presenting information, and finally checking to see what they learned, going back to reteach and recheck as necessary. Is this a reasonably complete description of the teaching/learning process?
The answer is, no, it is not. The fact that many teachers adhere to this oversimplified perception of the process offers a good explanation for why many of their students fail to learn. The teaching/learning process can be much better described by the eight phases of learning described by Gagne (1985), shown in Figure 3.2.

Figure 3.2. The eight phases of learning (based on Gagne, 1985).
In order for effective learning to take place, the learner must go through all eight of these phases. A serious breakdown at any one phase or a cumulative breakdown over several phases can bring learning to a halt. When teachers, textbook writers, computer programmers, or others decide to develop instructional materials or presentations, it is important that they verify that all eight of these phases will occur.
If the instructional designer does not plan for all eight phases, then either (1) some other person or material must supply the missing steps or (2) effective learning will not occur. The following paragraphs briefly describe each of these phases of learning:
When we say that the learner must go through all eight of these phases in order for learning to occur, this does not mean that the teacher is the person responsible for causing all eight of them occur. Somebody (usually either the teacher or the student) must see to it that all of these phases occur, but the actual role of the teacher will vary from situation to situation and from student to student. For example:
- The teacher might give an introduction to a topic that catches the student's attention (phase 1) and causes the student to develop an expectancy (phase 2) that it would be interesting to know more about the topic.
- The student might then open the textbook and find a good presentation that focuses his attention exactly on the key points necessary to understand that topic (phase 4).
- While reading the textbook, the student might without even being aware that it is happening bring to mind information that he already has previously learned that is related to the text presentation (phase 3).
- The student might easily fit the information into long-term memory by relating it to previous knowledge; or he may be concerned that he might forget the information and run a computer program that offers a drill on the topic to make it easier to retrieve it later (phase 5).
- The learner might ask himself questions about the topic or answer review questions published in the textbook; and eventually he might take a test designed by the textbook company and administered by the teacher (phase 6).
- While studying from the textbook, the student might check the answer key to see if his responses are correct; and the teacher would grade the test and return it to the student (phase 7).
- After successfully passing the unit quiz, the student might still occasionally review the material in order to keep it available for the final examination. In addition, he might find occasions to generalize the information to other settings by applying what he has learned when he sees the relationship of the information to other problems or topics (phase 8).
If the learner does all these activities by himself, effective learning will occur. If any phase does not occur or occurs imperfectly, learning will be weakened. In such cases, the teacher should intervene to help the learner accomplish the activities that comprise that phase of learning. For example, if the student does not respond on his own, the teacher could assign review questions as a homework assignment, call on the student in class, provide class time to let students study together, or supply interesting problems that stimulate the learner to use the information that was encoded during phase 5.
Amazing Anecdote! One night a wife found her husband standing over their baby's crib. Silently she watched him. As he stood looking down at the sleeping infant, she saw on his face a mixture of emotions: disbelief, doubt, delight, amazement, enchantment, skepticism.
Touched by this unusual display and the deep emotions it aroused, with eyes glistening she slipped her arm around her husband.
"A penny for your thoughts," she said.
"It's amazing!" he replied. "I just can't see how anybody can make a crib like that for only $46.50."
Moral of the story: Don't automatically assume that someone else's selective perception is focused where yours is.
The main features of the phases of learning are summarized in Table 3.1.

Phase Examples of
Failures Solutions for
Failures What the computer can
do Student ignores
teacher. Student is falling
asleep. Change
stimuli. Call for
attention. Increase level of
arousal Computer graphics can often catch and
hold learners' attention. Teacher doesnt
specify objectives Students culture
doesnt value stated goal. State
objectives. Employ principles of
motivation. Understand culture and
individual differences. The Computer can display clear objectives
- often as part of pulldown menus or hotlinks. Gamelike aspects of computer programs can
often add additional expectancies, which are more immediate
and compelling. Example: Seeing a reason to learn
grammar. Student not ready to
receive information from lesson. Student might retrieve a
misconception
rather than accurate information. Absence of previous
overlearning
makes retrieval difficult. Review prerequisite
knowledge. Teach missing skills and
concepts. Overlearn important
skills and concepts. The computer can branch easily to
prerequisite information. The computer can be programmed to seek
out and correct the learner's misconceptions. The computer can supply opportunities for
overlearning. Attention deficit
disorder causes failure to attend. Discipline problems cause
distractions. Teacher or materials fail
to direct attention. Treat
disorder. Use effective management
and discipline techniques. Use Media to direct
attention. The computer can isolate information and
focus on it concisely in a single screen. By asking questions about what is being
presented and using effective graphics, the learner can be
almost forced to direct attention where it needs to
go. Student fails to
encode. Students background
does not supply necessary structures. Students
misconception
causes faulty acquisition. Use long-term memory
strategies. Teach culture or adapt to
students culture. Confront and clarify
misconceptions (looping back to Phase 3). The computer can present real-life
contexts that will help the learner to itegrate information
with what he/she already knows. The computer can present a variety
of situations, so that individual learners can relate
information to their own unique backgrounds. Student fails to practice
a skill or concept. Subsequent information
interferes with earlier learning. Learning disability
interferes with response It's unrealistic to
expect learner to perform. Provide practice
opportunities, wait time, learning probes, etc. Prevent retroactive
interference. Treat
disability. Have a model perform the
behavior and receive feedback The computer can give the learner an
opportunity to try out what has been learned. The computer can do this by either
supplying an artificial situation or by facilitating
interaction with the natural events of the real
world. Teacher fails to provide
feedback. Student doesn't recognize
or like feedback. Student receives no
direction from feedback. Student gets feedback on
wrong task. Provide
feedback. Teach self
regulation. Make sure reinforcement
is reinforcing. Use corrective feedback -
not just negative feedback. Make sure tests are
valid. The computer can provide immediate
feedback, if it is programmed to do so. The computer can also permit natural
feedback to occur as a result of interactions with the wider
world that can be accessed via computer. When feedback calls for looping back to
earlier steps, the computer can often facilitate this
looping process. Student cannot find key
to trigger recall. Student learns, but then
forgets Student is restricted to
original context. Student relies on rote
memory rather than understanding. Use distributed
practice. Use
overlearning. Use variety of examples
during instruction. Teach metacognitive
strategies. The computer can make repeated practice
(e.g., drills)
easily available at convenient times. The computer can supply situations in
which the learner can apply what has been learned in
academic settings.
