In cosa sono competente/esperto? Come ho raggiunto la competenza? Dopo quanto tempo? Quali sono le skills (abilità) necessarie in questo campo? In che modo posso giudicare il livello di competenza di un’altra persona?
Domain Skills Senso-motoric skills are externally visible. They can be easily acquired by visualising the processes and learn through observations. Cognitive skills run inside human mind. Their non-visible nature demands a more sophisticated learning process.
What is the best suitable theoretical framework for facilitation of cognitive skills?
Cognitive apprenticeship framework Modelling : Learners study the task pattern of experts to develop own cognitive model Coaching : Learners solve tasks by consulting a tutorial component of the environment Fading : Tutorial activity is gradually reduced in line with learners’ improving performance and problem solving competence
Phases of Cognitive apprenticeship 1. World knowledge (initial requirement) 2. Observation of interactions among masters and peers 3. Assisting in completion of tasks done by master 4. Trying out on own by imitating
Phases of Cognitive apprenticeship 5. Getting feedback from master 6. Getting advise for new things on the basis of results of imitation, comparing given solution with alternatives 7. Reflection by student, resulting from master’s advice
Phases of Cognitive apprenticeship 8. Repetition of process from 2 to 7 Fading out guidance and feedback Active participation, exploration and innovation come in 9. Assessment of generalisation of the tasks and concepts learnt during repetition process
Constituents of Domain Competence Know-why Know-how Know-how-not Know-why-not Know-when Know-when-not Know-what logical processes Know-about Easier to learn from mistakes An example of the know-how aspect of know-when is the temporal context required for an appropriate sequence of operation An example of the know-why aspect of know-when is the environmental and behavioural contexts required for making a decision Action oriented and experiential Reflection oriented and abstract Difficult to learn from mistakes Trial and error Context oriented and both experiential and abstract Awareness oriented
Constituents of Domain Competence Know-how It has an operational orientation. It is mainly action-driven and hence pre- dominantly experiential. It is difficult to inherit it from someone else’s experience. Know-how-not Learning by mistakes. Examples : Computer simulation and virtual reality
Constituents of Domain Competence Know-why It has a causal orientation. It is mainly reflection-driven and therefore based on abstraction. It can be inherited from someone else’s line of reasoning. Know-why-not Logical processes. Needs deeper reflection.
Constituents of Domain Competence Know-when (and -where) It has a contextual orientation. It provides the temporal and spatial context for both the know-how and know-why. It is thus both action and/or reflection driven.
Constituents of Domain Competence Know-about It has an awareness orientation. It includes above three types of knowledge in terms of know-what. It also contains information about the environmental context of this knowledge.
How about computers? Reflect upon: Which constituent of knowledge can be successfully facilitated through computers? Know-howKnow-why Know-whenKnow-about
Affective Knowledge Taxonomy (Krathwohl et al,. 1964)
Affective Knowledge Taxonomy (Krathwohl et al,. 1964) Receiving is being aware of or sensitive to the existence of certain ideas, material, or phenomena and being willing to tolerate them. Responding is committed in some small measure to the ideas, materials, or phenomena involved by actively responding to them
Affective Knowledge Taxonomy (Krathwohl et al,. 1964) Valuing is willing to be perceived by others as valuing certain ideas, materials, or phenomena Organization is to relate the value to those already held and bring it into a harmonious and internally consistent philosophy Characterization by value or value set is to act consistently in accordance with the values he or she has internalized
Psychomotor Knowledge Taxonomy (Harrow,1972)
Psychomotor Knowledge Taxonomy (Harrow,1972) Reflex movements are actions elicited without learning in response to some stimuli Basic fundamental movement is inherent movement patterns formed by combining reflex movements and is the basis for complex skilled movements Perceptual is interpretation of various stimuli that enable one to make adjustments to the environment (visual, auditory, kinesthetic, or tactile discrimination).
Psychomotor Knowledge Taxonomy (Harrow,1972) Physical activities require endurance, strength, vigor, and agility, which produce a sound, efficiently functioning body Skilled movements are the result of acquisition of a degree of efficiency when performing a complex task Non-discursive is communication through bodily movements ranging from facial expressions through to sophisticated choreographies
Bloom’s Cognitive Knowledge Taxonomy
CompetenceSkills Demonstrated Knowledge Observation and recall of information Knowledge of dates, events, places Knowledge of major ideas Mastery of subject matter Question like: What is…? Understanding Understanding information Grasp meaning Translate knowledge into new context Interpret facts, compare, contrast Order, group, infer causes Predict consequences Question like: How would you compare and contrast…?
Bloom’s Cognitive Knowledge Taxonomy CompetenceSkills Demonstrated ApplicationUse information Use methods, concepts, theories in new situations Solve problems using required skills or knowledge Question like: Can you organize ___________ to show…? Analysis Seeing patterns Organization of parts Recognition of hidden meanings Identification of components Question like: How would you classify…?
Bloom’s Cognitive Knowledge Taxonomy CompetenceSkills Demonstrated Synthesis Use old ideas to create new ones Generalize from given facts Relate knowledge from several areas Predict, draw conclusions Question like: Can you predict an outcome? Evaluation Compare and discriminate between ideas Assess value of theories, presentations Make choices based on reasoned argument Verify value of evidence Recognize subjectivity Question like: Do you agree with…?
