The key principles of Stikky Learning Techniques
are:
- Small units: sequences are composed of small steps, each of
which is easily grasped (and the sequences themselves require
less than 30 minutes to complete)
- An illustration on every page
- Frequent testing of what has been learned with instant
feedback
- Regular reward either explicit ('congratulations') or
implicit (the reader accomplishes something they consider an
achievement)
- Self-pacing with guidance ('this should take around 20
minutes')
- Task-orientation ('how do I find which way is north?')
- Similarity of the learning environment and the real-world
environment, so cartoons, abstractions or simplifications are
used sparingly and quickly removed to avoid forming crutches
- Motivational elements ('which will prove important later')
which were designed with the help of a Hollywood screenwriter
- Expanding rehearsal: the interval between re-testing of
specific knowledge gradually lengthens (eg, pause points)
- An awareness of 'mental modules': that certain abilities are
innate in humans (such as counting and language) and others have
to be learned (algebra, tap dancing)
- The 'santa claus' effect: it is acceptable to bend the truth
of non-essential points to make a significant simplification
that can be easily unlearned later (eg, the Big Dipper is not a
constellation)
- A high criterion: readers are expected to have perfected
material before moving on ('if you are unsure, now is a good
time to go back')
- 'We are all rocket scientists': the belief that just about
anyone can learn just about anything given enough time and if
the material is presented in small steps, so the fault is more
likely to be in the presentation than the learner.
Some of these concepts derive from software usability
(task-orientation and similarity of environments). But most derive
from extraordinarily successful learning models of the 1960s and
1970s such as Keller's Personalized System of Instruction and
Bloom's Learning for Mastery (and less successful models from even
earlier, notably Skinner's Programmed Learning).
Stikky is, as far as we are aware, the first application of these
ideas in a commercially-available How To format.
Programmed Learning
Despite great excitement, largely driven by B F Skinner, Programmed
Learning did not prove significantly more effective than traditional
learning methods (Kulik, Cohen Ebeling, 1980). Some of its
principles, though, informed later and more important methods:
- Small units of 'frames'
- Overt responses
- Immediate feedback and correction
- Rewards
- Self-pacing.
Learning for Mastery
Bloom's Learning for Mastery (Bloom, 1968/81) is based on the rule
that students are only allowed to progress from one module to
another after mastering it completely. A student's aptitude
determines how much time they need to master a unit, not the
likelihood that they will ever be able to master it. Other than this
rule, Learning for Mastery is flexible in how it is actually
implemented.
A meta-analysis by Block and Burns (1977) found Learning for
Mastery had an effect equivalent to moving the average student in a
class into the top 20%. In addition, the approach had a positive
impact on students' interest in a subject and, understandably, their
self-confidence. A very large trial in Korea produced similarly
dazzling results (Kim, 1971).
Personalized System of Instruction (PSI)
Keller's PSI is also based around the mastery criterion (Keller,
1968)and the following:
- Small units, around two hours long
- Self-pacing
- Written materials and written answers
- Unit tests with fast feedback provided by a 'proctor'
- At least 90% score required before progressing
- Lectures for motivation purposes only.
A meta-analysis by Kulik, Kulik and Cohen (1979) found that PSI
students achieved final examinations results 8 percentage points
higher than conventionally taught students.
Research also independently confirmed the value of small units,
fast feedback (delayed feedback reduced effectiveness) and high
mastery criterion-but the main value of proctors and self-pacing was
found to be that students like them.
Illustrations
Levin, Anglin and Carney (1987) review research demonstrating the
(not particularly surprising) finding that illustrations
significantly aid learning.
Expanding Rehearsal
A number of studies, for example Melton (1963), show that the
greater the separation between subsequent repetitions of a learned
item, the greater the productivity of learning, assuming the delay
is compatible with correct recall. The same effect has been
encapsulated in a 'smart flash cards' software application,
Supermemo.
Applying this concept in a book that demands around an hour of the
reader's time proved a challenge. It resulted in the 'pause point'
at which, unusually, the reader is asked to stop reading to allow
time between rehearsals.
Mental Modules
Evolutionary psychologists developed the concept of innate mental
modules that would have conferred a survival advantage in the
evolutionary environment of 200,000 years ago. Steven Pinker (2002)
provides a tentative list including intuitive physics, spatial sense
and language. The theory (not yet research) suggests that learning
material that is closely related to these factory-fitted modules
will be much easier with implication for learning step size.
(The material on educational methods and research above draws
heavily on Ken Spencer's excellent pages: Information Technologies
and Student Learning.)
