Los Angeles Unified School District Division of Special Education Schools for All Children Developmental and Learning Characteristics of Students with Mental Retardation Donnalyn Jaque-Antón Associate Superintendent
Definition • A disability that originates before the age of 18 and is characterized by significant limitations both in intellectual functioning and in adaptive behavior as expressed in conceptual, social, and practical adaptive skills AAMR 2002
Significantly subaverage general intellectual functioning, existing concurrently with deficits in adaptive behavior and manifested during the developmental period, that adversely affects a child’s educational performance CFR 300.7(c)(6)
Causes of Mental Retardation • Chromosomal abnormalities including genetic, metabolic and neurological disorders • Congenital infections • Prenatal drug exposure • Perinatal/postnatal factors
Levels of Mental Retardation • Mild • Moderate • Severe • Profound
Adapted from: Institute On Violence and Destructive Behaviors, University of Oregon (1999) Significant/ Pervasive Support Supports are Constant, High Intensity Limited Support Supports are Needed Consistently Intermittent Support Supports are on as Needed Basis
Levels of Support for Students with Mild Mental Retardation • Intermittent Supports • As needed basis • High or low intensity • Most likely to be required at life transitions
Levels of Support for Students with Moderate Mental Retardation • Limited Supports • Needed consistently over time – but not on a daily basis • Non-intensive • Transitional sensitive
Levels of Support for Students with Severe Mental Retardation Significant Supports • Regular and frequent involvement • Situational sensitive
Levels of Support for Students with Profound Mental Retardation • Pervasive Supports • Consistent • High intensity • Across environments
Educational Implications Attention, memory, and decision making • Good attention to task at hand • Decision-making capability varies • Difficulty generalizing
Educational Implications (continued) Cognitive characteristics related to skill acquisition: • Difficulty in organizing thought • Persistence in using incorrect methods • Difficulty in self-evaluation • Less preparation and slower movement times
Student learns through direct interactions with things activities & people Teacher provides activity-based “hands-on” learning experiences Addressing Educational Challenges
Student learns through associations Teacher uses meaningful context such as daily routines & organization of materials Addressing Educational Challenges (continued)
Student’s understanding is likely based upon their own perceptions, experiences, or scripted answers that are not completely understood Teacher explicitly links cause–effect, especially through social skills instruction Addressing Educational Challenges (continued)
Student learns through repetition Teacher provides multiple opportunities to learn and practice skills systematically Addressing Educational Challenges (continued)
What is Systematic Instruction? • Identification of the learning target • Breaking down the learning target into incremental steps • Knowing where each student enters the learning sequence • Practicing across environments
Systematic Instruction Includes • Task Analysis • Teaching Strategies • Reinforcement, shaping, fading and prompting hierarchies • Data collection
Task Analysis Break down a task into a behavior chain consisting of separate, teachable, smaller steps/links • Steps/links should be individualized to meet student’s needs • Behavior chains range in amount of steps/links
Teaching Strategies Direct Instruction is often used to teach rote association, vocabulary skills, “early academic skills,” and sometimes “behavior scripts”
Teaching Strategies • Tasks are broken into small skills • Tasks are taught using a structured format (Stimulus>Response>Consequence) • Provides multiple opportunities to practice
Teaching Strategies • Effective for varied skills and group size • Keep the individual or groups attention by serial responding, active participation, pacing and varying materials • Consequence tends to be an external reinforcer
Reinforcement A tool used to support, establish, maintain, or generalize a behavior • Kinds of reinforcers • How much
Shaping/Fading/Prompting • “Shape” or prompt the correct response • Block error or use maximum prompt to cue correct response • Verbally prompt correct response • Model correct response • Reduce choices (simplify task) • As student gains mastery fade or reduce the prompts
Data Collection We need to: • Monitor student learning • Monitor effectiveness of teaching strategies • Write observable, measurable goals and objectives • Demonstrate adequate yearly progress
Adapted from: Institute On Violence and Destructive Behaviors, University of Oregon (1999) Significant/ Pervasive Support Supports are Constant, High Intensity • Alternate curriculum or Life Skills • Intensive social skills training • Parent training and collaboration • Multi-agency collaboration (wrap-around) services Limited Support Supports are Needed Consistently • Modifying Core curriculum • Varying response output • Small group targeted instruction • Pre-teach/Re-teach/Remediation • Social Skill Training Intermittent Support Supports are on as Needed Basis • Based on Core Curriculum • Universal Access • Based on individual student’s need • High-quality instructional methods • & strategies that ensure progress • Frequent assessment to monitor progress • Positive reinforcement systems
Curriculum An applied curriculum that connects the general education concepts being taught with the context where those concepts are utilized in managing one’s everyday life is key to making the standard curriculum accessible for students with moderate to severe disabilities.

Strategies for Access to Standards-based Instruction • Curriculum provides multiple means of representation • Alternate modes for subject matter • Visual • Auditory • Differentiated
Strategies for Access to Standards-based Instruction (continued) • Curriculum provides multiple means of expression • Allows students to respond with their preferred modality • Accommodates the differing cognitive strategies and motor systems of students
Strategies for Access to Standards-based Instruction (continued) • Curriculum provides multiple means of engagement • Students’ interests in learning are matched with the mode of presentation and their preferred means of expression • Students are engaged Center for Applied Special Technology (CAST)
Relates to Self-determination Motivation Positive behavior support Structuring Choice-Making Within a task Between tasks Order of tasks With whom to do task “More” of task Yes or no Importance of Choice-Making
Positive outcomes • Can live independently or semi-independently • Can develop meaningful social and personal relationships • Can be meaningfully employed within the community • Can enjoy a high quality of life
