What are Incidental Teaching Methods (ITM)?
Incidental Teaching is used to get elaborated language or to expand on
existing skills by waiting for another person to initiate conversation
or a topic and then responding in ways that ask for more language from
that person (Hart & Risley 1982). Learners in this profile are able
to learn concepts with minimum exposure and highlighting of concepts to
make the critical features salient.
How does TLC utilize ITM? TLC
uses incidental teaching as a mechanism of building on the child's
existing skills by capturing situations as they occur to promote the
use or expansion of language or learning. Incidental Teaching occurs in
the natural environment and is less structured than using a natural
environmental teaching plan (NET plans).Once the learner demonstrates
the ability to first learn through a high number of discrete trials and
through structured NET Plans, the topography of the program is shifted
and skills are taught more incidentally. As the child's learning
profile indicates that the child needs fewer exposures to a concept to
learn the intended content, the child's program shifts to incidental
teaching which is less structured and less intense in exposure.
How Does ITM Compare to Discrete Trial Instruction?
|
ITM
- Child initiates
- No structured learning environment
- Rewards are the materials
- Rewards are related to initiation
- Low exposure to learn
|
|
Discrete Trial
- Teacher Directed
- Structured environment
- Selected by instructor
- May be unrelated to task
- High number of learning opportunities
