Data-based Decision Making
Advantages •High validity and reliability •Directly comparable to peers • Shows presence/absence of problem Limitations •No modification to match student needs
Structured Interviews
Advantages •Adapt to student needs •Puts students at ease Limitations •Responses difficult to interpret •Cannot compare to norms
Unstructured Interviews
Whole Interval Recording
Number of behaviors that occur during a specific period
Most useful with behaviors that are discrete and short in duration
Frequency or Event Recording
•Mark whether the behavior occurred at least once during the short observation interval.
Partial-Interval Recording
Time Sampling Interval Recording
Length of time behavior lasts
Duration Recording
Time between onset of stimulus that initiates behavior
Latency Recording
Momentary Time Sampling
Universal Screening (Purpose)
Universal Screening (Benefits)
Universal Screenings (Liabilities)
* Better to err on the side of caution and give support (least dangerous assumption)
Cognitive measure (group administered); monitor yearly performance (option)
Cognitive Assessment Test (CogAT)
CBM’s conducted several times per year to identify students who need additional support
System to Enhance Education Performance (STEEP)
Subskill Mastery Measurement (SMM)
General Outcome Measurement (GOM)
Based on systematic and repeated measurement of behavior over specified time
Progress Monitoring (RTI)
Variability and Sources of Error (RTI)
* Condition: performance changes following a change; compared to peers or benchmark
Analysis of level (RTI)
Analysis of Trend (RTI)
Current level, trend, and variability of behavior (prior to intervention)
Baseline (RTI)
Evaluation Points (RTI)
Reason to use RTI data (RTI)
Student whose teacher’s use data-based decisions learn more than students whose teachers do not rely on such data
