SP Praxis Exam Flashcards
Forms of data collection
background data collection/problem identification lvl, screening lvl, progress monitoring/RTI lvl, formal assessment
background data/prob identification lvl
identify/label the problem
ex. student records, staff intervention, medical records, review previous interventions, developmental history
screening lvl
identify at-risk students or students who struggle with academic work
progress monitoring/RTI lvl
data to determine effectiveness of intervention
formal assessment
(SpEd lvl) Cognitive, Social Emotional data from formal standardized measures
interview techniques
structured, unstructured, semi-structured interviews
structured interviews
standardized/formal, tells presence/absence of problem (not lvl of function), can compare with norms; CANNOT MODIFY FORMAT AS THIS IS STRICT
unstructured interviews
conversational/relaxed interviews; responses can be difficult to interpret and cannot be compared with social norms
semi-structured
combo of both structured and unstructured interviews that allows for follow up questions and flexibility
observational techniques
whole interval recording, frequency/event recording, duration recording, latency recording, time-sampling interval recording, partial-interval recording, momentary time sampling
whole interval recording
Bx recorded when it occurs during whole time interval; good for continuous Bx during short duration
frequency event recording
record # of Bx during specific period
duration recording
length of time specific behavior lasts
latency recording
time btw initiation of stimulus of behavior
time-sampling interval recording
divide time period into equal intervals & record behavior if occurs; effective when unable to determine start/end of behavior or when short period of time available to observe
partial-interval recording
multiple behavior scored as 1 if occurs at any time in interval; effective when behavior occurs at low/inconsistent rate
momentary time sampling
behavior scored as present or absent within time interval (least biased estimate of behavior)
Purpose of universal screening
see if modifications are needed in core curriculum while serving as guiding decisions for additional needed instruction
pros and cons of universal screening
Pros: cost-effective, time-efficient, easy to administer
Cons: can misclassify students
least dangerous assumption of universal screening
it is better to give support to students who don’t need it than not giving support to students who need it
universal screening measures
curriculum-based (CBM), fluency-based indicators of skills, cognitive assessment test (CogAT), state education agencies, & systems to enhance educational performance (STEEP)
curriculum-based measures (CBM)
used only if aligns with norms, benchmarks, and standards; specific forms of criterion referenced assessments where curriculum, goals, and objectives are “criteria” for assessment items
ex. DIBELS for reading fluency
fluency-based indicators of skills
initial-sound fluency, letter-naming fluency, phoneme segmentation, nonsense word fluency, oral-reading fluency
cognitive assessment test (CogAT)
cognitive measure; group administered and used as a screener
state education agencies
formal test administration to monitor growth in math, reading, and writing
systems to enhance educational performance (STEEP)
schools conduct curriculum-based measures during year in math, reading, and writing to find students who need more support
RTI Process
1) identify academic/behavioral concerns by teacher/parent
2) SP collects data and screens info on student
3) collect baseline info on areas of concern
4) Use research-based intervention & give tests for post-int. progress; track/analyze test data
5) examine difference in performance (baseline/post-int.); if student does not grow from intervention in 30-60 day THEN SpEd eval considered
How to decide what to assess?
subskill mastery measurement (SMM) & general outcome measurement (GOM)
subskill mastery measurement
info to see if intervention for behavior is effective (collected frequently: daily)
general outcome mastery (GOM)
student progress on long-term goals (collected once a week)
how to analyze and present data
progress monitoring, frequency data, behavior chart (x-axis: time intervals in days/weeks), levels of analysis
progress monitoring
systematic and repeated measurement of behavior over specified time
frequency data
% correct, # of opportunities to respond are recorded/displayed
levels of analysis
variability, level, & trend
analyzing variability in progress-monitoring data
1) effectiveness of interval is defined by ability to change behavior
2) confounding variables include uncontrolled subjects/environmental factors (must control these variables to ensure effectiveness of interval is actually measured)
3) measurement error
measurement error
occurs if observer is not looking when Bx occurred or CBM not administered correctly
consideration of mitigating factors
consider extraneous factors for intervention effects like uncontrolled personal and environmental changes
RTI analysis of level
average performance within a condition; performance compared with peers or benchmark
RTI analysis of of trend
student’s performance increases/decreases across time; multiple measures needed to estimate the trend (calculate slope w/ SPSS); visual analysis used to estimate general pattern of change
baseline
status prior to intervention; sees current lvl, trend, and variability
general RTI evaluation points
1) Baseline data shouldn’t have high/low spikes in 3 consecutive data points
2) 80% of data points should fall within 15% of mean (avg)
3) Collect minmum # of baseline pts (3-5)
4) Practical considerations affect amount of data collected
3 ways to describe behavior
level, trend, variability)
how to make decisions on RTI data
1) Consider if good # of data points in baseline and intervention
2) determine if change in behavior relates w/ change in conditions (immediate change = from intervention)
3) have goal based on local norms, benchmarks, or class-comparison norms
4) if 2-3 points are below trend line = change interval
5) if slope of trend line is below aim line = change interval
6) no correct responses for 3-4 days = change interval
7) highly variable data due to extraneous variables like student attention, noncompliance, motivation, etc.
8) % correct < 85% = provide modifications, prompts, modeling, corrective feedback
9) if slow growth = focus on increasing student rate of correct responses thru repeated practice and motivation
If RTI fails…
do SpEd eval
standardized tests w/ norms older than 10 years
use with caution due to regression problems in older norm data
SpEd evals include
cognitive, achievement, communication, motor skills, adaptive skills, social, emotional, and behavioral functioning, sensory processing, assessments
informal measures of emotional/behavioral/social skills
of office referrals, suspensions, class-based disciplinary procedures to see levels of problem behavior
FBA
comprehensive and individualized method to identify purpose and function of behavior; used to develop a plan to modify factors that cause problem Bx and teach replacement behaviors
FBA steps
1) describe prob Bx (operationally define)
2) perform assessment (review records, observations, interview student, teacher, parents)
3) Evaluate assessment results (finds patterns of Bx & purpose of target Bx)
4) Develop hypothesis
5) form intervention plan
6) implement intervention
7) evaluate effectiveness of plan (place emphasis on antecedent to Bx to determine what triggers it in the environment)
Social/Emotional measures
must need at least 2 forms (parent & teacher); multiple raters and settings (ex. BASC-3)
Curriculum-based assessment (CBA)
broad assessment program includes CMB and structured observations
CBM measures must….
1) based on systematic procedures for frequent collection & analysis on student performance data
2) examine students across time to see intervention effectiveness
3) identifies at-risk students
4) provides normative and statistically sound information for students, staff, and parents
(ex. Reading: student read 2 mins and calculate words correct/incorrect compared with class; Writing: listen to passage, write 2 mins; Spelling: 2 min spelling test; Math: 3 min math probs)
ecological assessment
see “goodness of fit” for student and learning environment
ICEL
Instruction, Curriculum, Environment, Learner; analyze work samples, prior grades, and assessments, collect info from parent/teacher/student, observe during instruction and other environments
intellectual disabilities (ID)
assess with cog & adaptive measures; SS 70 or below needed on COG test (like WISC-V), origin of disability before 18 yrs
ID deficits/impairments in adaptive functioning in areas of…
communication, self-care, social skills, use of community resources, self-direction/independence, functional academics skills, employment, leisure, physical health issues
Scales to use for ID
Vineland Adaptive Behavior Scales (VABS-4), Adaptive Behavioral Assessment (ABAS-4)
What to consider of Non-English speaking students…
developmental history, languages spoken/heard, language dominance/presence, language proficiency in both languages must be assessed to find the dominant language
language differences vs. language disorders
- disorder must be present in native language and English
- testing must be conducted in native/strongest language
- tests w/ formal and informal speaking contests
- patterns of language usage described & error patterns determined
- child performance compared with others w/ similar cultural/linguistic experiences; compared with people of same cultural group/dialect
** use standardized tests w/ interpreter is psychometrically weak and not best practices
** using interpreter helps collect info, but score validity is low
** informal alternate assessments are < discriminatory & provide info about student current skill level
concepts related to learning & intelligence
Premack Principle, immediacy, negative reinforcement, positive reinforcement, fixed-ratio reinforcement, variable ratio, frequency/duration/intensity, shaping, extinction, & punishment
Premack Principle
principle by David Premack in which lower level behavior can be shaped by higher level (desired) behavior; AKA contingency learning (first complete less desired Bx to get desired Bx)
Ex. do homework to play outside
immediacy
consequences occur immediately after Bx for effective reinforcement
negative reinforcement
Bx increases w/ negative reinforcement (stimulus removed = Bx increases); often confused with punishment
positive reinforcement
Bx occurs; rewarding stimulus provided & Bx increases
fixed-ratio reinforcement
specific # of Bx must happen before reinforcer given
variable ratio
of Bx needed varies to receive reinforcer
frequency, duration, and intensity
measurable and key parts to Bx modification plans
shaping
creates a Bx by reinforcing approximations of desired target Bx
extinction
eliminating reinforcers/rewards terminates problem Bx
punishment
giving undesired stimulus based on problem Bx
theories of intelligence and measurement
1) Spearman’s theory of intelligence: 2 factor theory of intelligence
2) Thurstone’s Primary mental abilities
3) Cattle-Horn-Caroll (CHC) theory of cognitive abilities
4) Das-Naglieri PASS model

created by Charles Spearman where he created modern statistical foundation of intelligence tests and believed in general intelligence factor known as “g”; “g” is seen all over FSIQ scores
thurstone’s primary mental abilities
created by Louis Thurstone where he claimed there are 11 primary mental abilities
Cattle-Horn-Carroll (CHC) theory of cognitive abilities
