When a new idea is introduced to a learner, it doesn’t just get poured into their mind like water into a bucket. e new idea is faced with integrating itself into the learner’s personal cognitive landscape.

Each person has their own, unique Cognitive Ecology—knowledge, concepts, experiences, schemas, and beliefs that makeup what Kenneth Strike and George Posner call a “Semantic Syntactical Network of Concepts.” [Hang onto that notion—we’ll come back to it later]. Generally speaking, people don’t let go of aspects of their Cognitive Ecology easily—if a new idea introduced doesn’t "t into their network of concepts easily (known as ‘assimilation’), then the individual must alter their network of concepts in order to "t this new idea into it (or ‘accommodate’ it). It’s kinda like having a typical two-story home and saying you want to put an indoor pool in the middle of it—successfully doing so isn’t like just adding a wing onto the house, instead you’d have to take apart the whole thing and rebuild it in a new way.

As a result, a person’s current Cognitive Ecology will in#uence their production of a new conception.

For all these reasons, it’s critical to identify the learner’s current Cognitive Ecology before introducing a new conceptual model. Doing so will allow the instructional designer to strategically create an instructional experience (or cognitive journey) for the learner, which increases its chances exponentially of producing a conceptual change.

How can you unearth a learner’s Cognitive Ecology? ere’s numerous things you can look to elicit which will give you a sense of the individuals beliefs and conceptions:

• Exemplars & Images - can they explain for you an example of what they think, or draw an image of their ideas?

• Analogies & Metaphors - can they come up with a metaphor or analogy that demonstrates what they believe?

• Past Experiences - can they talk about their past experiences that have led to their current conceptions?

• Anomalies - Are there parts of their conception that they can tell don’t quite “add up” in their head?

• Other Knowledge - Do they hold other conceptions, that relate to or interact with the one you are concerned with, that might inhibit the acceptance of a new conception?

ese are just some of the things to look for and expose in the learner’s current Cognitive Ecology.

To leverage a Conceptual Change, you must create in the learner dissatisfaction with their current conception, by presenting them con#icting and/or alternative ideas. A good instructional hook will get them to engage in your cognitive journey.

As the instructional designer, your job is to shake that foundation by creating an experience for them that generates internal dissatisfaction with their current conception.

e neat thing about these instructional experiences is that they can often expose current conceptions, if you weren’t able to decipher them easily before this. What does these instructional experiences need to look like? e general answer is they need to make the learner unhappy with their previous conception—which of course will likely be speci"c to the concept you are driving at. However, there are certain things you can strive for.

• EXPOSE current weaknesses in their current conception

• create an outright ANOMALY in the mind of the learner—one of the most powerful ways of leveraging dissatisfaction. Is there an experience you can create for the learner that will leave their current conception coming up short?

• a NEW EXPERIENCE that is unlike anything they’ve had before can open new cognitive channels for the learner, thereby "tting better into their overall ‘Semantic Syntactical Network of Concepts”.

Although ANOMALIES are one of the most powerful mechanisms for leveraging cognitive dissonance, they don’t come easily. Providing the learner with an anomaly leaves their conceptual ecology on very shaky ground. Changing their cognitive ecology to accommodate the anomaly is the most difficult of the learner’s options—it’s much easier for the learner to just reject what they experienced, disregard the experience as irrelevant, or just try to compartmentalize their knowledge so that the new beliefs they are forming do not interact with their prior conceptions.

In order for the anomaly to successfully do its job, the learner must:

1. understand why the experience produced an anomaly

2. believe they must reconcile this experience with their previous conceptions

3. have the desire to put the cognitive work into doing this

4. fail at attempts to assimilate the new knowledge

It may seem daunting, but the good news is that there is extensive research showing the cognitive dissonance is a powerful mechanism, and many learners will seek to reconcile disconnects in conceptions in order to relieve this dissonance.

Now that the learner’s conceptual foundation is on shaky ground and they seek to re-concretize their conceptual ecology, you can help them build the bridge to new conceptions. Presenting the new conception will be successful if that bridge consists of 2 parts:

• Minimal Understanding of the new conception, and

• Initial Plausibility of the new conception

For minimal understanding, the learner must be given a framework they can digest, or can construct this framework on their own. Metaphors and analogies are useful tools in this area, as they provide a familiar onramp for an unfamiliar concept.

For Initial Plausibility, the new concept must at least appear to integrate with their overall semantic network and consistent with other theories, knowledge, and prior experiences they hold. Additionally, the new concept must appear to resolve the anomaly. It also helps if the new conceptions appears analogous to another conception to which the learner is already familiar.

If the learner is willing and able to go this far on the cognitive journey, they are in good position to begin to build a new foundation for their conception. Continued instructional experiences and learning opportunities designed for the new conceptual model will result in the building, assimilation, and concretization of the new conceptual model. By being able to "t this new conceptual model into their Semantic Syntactical Network of Concepts, the learner is likely to have a strong and enduring Conceptual Ecology.
