activities studied
Activities Studied
  • Airplane pilots,
  • Chess players,
  • Automobile drivers,
  • Adult learners of a second language
five stages
Five Stages
  • Novice
  • Advanced Beginner
  • Competent
  • Proficient
  • Expert
best opportunity to observe stages
Best Opportunity to Observe Stages
  • Unstructured problems
  • Number of potentially relevant facts enormous
  • Variety of solutions extensive
novice
Novice
  • The novice follows rules
  • Specific rules for specific circumstances
  • No modifiers
  • “Context free”
  • Don’t feel responsible for other than following the rule
slide7
The early medical student is taught to obtain an EKG for chest pain, without other modifiers.
advanced beginner
Advanced Beginner
  • New “situational” elements are identified
  • Rules begin to be applied to related conditions
  • Decisions still are made by rule application
  • Does not experience personal responsibility
slide9
The more experienced medical student finds that dyspnea also might be associated with cardiac ischemia and orders an EKG for that situation as well.
competence
Competence
  • Numbers of rules becomes excessive
  • Learn organizing principles or “perspectives”
  • Perspectives permit assorting information by relevance
  • The experience of responsibility arises from active decision-making
slide11
The competent physician realizes the multitude of factors influencing the likelihood that a single symptom represents ischemia and has a decision tree to allocate probabilities balancing a number of factors in deciding when to order an EKG or other diagnostic modalities and begin treatment
proficiency
Proficiency
  • Intuitive diagnosis
  • Approach to problem molded by perspective arising from multiple real world experiences
  • “Holistic similarity recognition”
  • Learner uses intuition to realize “what” is happening
  • Conscious decision-making and rules used to formulate plan
slide13
The proficient physician realizes “this is an infarction” and then applies rules to decide about thrombolysis.
expertise
Expertise
  • Don’t make decisions
  • Don’t solve problems
  • Do what works
  • No decomposition of situation into discrete elements
  • Pattern recognition extends to plan as well as diagnosis
slide15
“This is an infarction and we should implement the following diagnostic and therapeutic interventions.”
when expertise fails
When Expertise Fails

The expert uses rules and explicit decision-making.

novice17
Novice

Novice:follows rules and does not feel responsible for outcomes.

advanced beginner18
Advanced Beginner

recognizes new situations in which the rules may be applied. Still does not feel responsible.

competent
Competent

Follows rules, applies an organizing “perspective” to determine what elements of the problem are relevant and feels accountable because of decision-making

proficiency20
Proficiency

The proficient learner uses pattern recognition arising from extensive experience to identify the problem (“what” is happening”) and rules and analysis in formulating the “how” of the solution. A sense of responsibility follows the decision-making.

expertise21
Expertise

immediately sees “what” is happening and “how” to approach the situation. Pattern recognition extends to management plan as well as diagnosis.

The utility of the concept of skill acquisition lies in helping the teacher understand how to assist the learner in advancing to the next level.
