Why CBI and Who’s Eligible? • Students’ with Low-Incident Disabilities1 • Students on a Functional Curriculum • Learning Characteristics • Cognitive • Acquisition • Generalization • Maintenance
Community-Based Instruction (CBI)1 • CBI is instruction conducted with actual materials in the natural environment where a functional skill is expected to be ultimately performed.
ADVANTAGES Opportunities to learn and to rehearse skills needed to participate in an integrated lifestyle Mitigates skill generalization Responding to actual stimuli and naturally occurring cues and antecedents Responding to natural consequences and criteria Access to age-appropriate environments and materials LRE CHALLENGES Time constraints Scheduling Transportation Costs Advantages & Challenges of CBI1
Implementing CBI Continuum of Scheduling Options1 • CBI Only • Classroom Simulation Only - instruction designed to approximate the natural environment in the classroom setting Advantages • Easier to implement • Can use and reuse materials • Less time consuming • Reduces possible student & parental embarrassment of not being able to perform a skill in the community • Reduction of risk factors and safety concerns Disadvantages • Minimal confidence that skills will generalize to natural environments (i.e., training and hoping) • Students are less likely to function independently in nonschool domestic, vocational, recreational/leisure, and community environments • Combined Schedules2 • Concurrent CBI and Classroom Simulation Instructional Schedules • Incorporating the advantages of both CBI and classroom simulation instruction
Percentage of Student Independent Performance Across Phases and Conditions3 Note. BL = Baseline, I = intervention, G = generalization, F = follow-up (two-weeks), a = Kruskal-Wallis test, * p < .05. SOI students were taught how to use a fax machine in order to send a fax CBI students were taught how to use a debit card to operate an ATM machine to withdraw cash CCD students were taught how to use a debit card to make a two-item purchase CSD students were taught how to use a copy machine to collate a newsletter
Classroom Simulation Instruction Continuum of Classroom Simulation Options4 • Materials range from entirely natural to completely artificial • Reconstructed replica to Black and white flashcards • Within the Continuum of Material Options • Static Picture Prompts • Video Modeling • Video Prompts • Computer-Assisted Instruction (CAI) • Self-Operated Auditory Prompts (SOAP)

Behavior Management • The degree to which students participate in CBI is often dependent on their ability to demonstrate appropriate behaviors while in the community • Behavioral Characteristics - Self-stimulatory behaviors, such as rocking and hand-flapping - Self-injurious behaviors, such as head banging and hand biting, and aggressive behaviors such hitting others and throwing objects • Access to these programs may be limited or even denied because of inappropriate behaviors • Inappropriate social behaviors are the most frequent reason students with intellectual disabilities fail to acquire or fail to maintain their employment7
Behavior Management • The use of brief functional analysis and intervention evaluation in public settings • Brief-Functional Analysis8 • Antecedent-Based Intervention • Response-Based Intervention • Social Validity
