Agenda/Update • Announcements – Ecological Inventory & Article Review #1 Due April 18th. • Updates to Wiki – Please check to see if all links work. – Still working on linking the articles for the article review. Article Review #1: Due April 18th, (April 13th for Wednesday Class) • Article Review Template • Rubric is Posted • Short presentation on Single-Subject Research Designs • Review article in your group… – This will be your entry activity – Everyone will complete a sheet Single Subject Research Systematic analysis using individual subjects as their own experimental control. Main message: – Single subject research is an approach to rigorous experimentation that involves small numbers of subjects, repeated observations of subjects over time, and employs research designs that allow each subject to provide his/her own experimental control. • Within-subject analysis • Fine-grained analysis across time and conditions Types of research Basic – gain knowledge for knowledge’s sake – May be no immediate or foreseeable application or implications for “real world” life Applied – research to gain knowledge or address issues/problems that have immediate application to “real world” life – Educational research is applied research Single subject research methods are used in basic and applied research – we’ll focus on applied research in the course Reasons for using single subject methodology Focus on an individual rather than group means – Interest is in the behavior of a single individual or on within-subject variability • A “group” may be treated as an “individual” – Group descriptive statistics may not "describe" any actual individual – Generalizations from a group to an individual are problematic in many instances • Predicting the behavior of a specific individual is different from predicting that of a “typical” individual Reasons for Using Single Subject Methodology (continued) Many populations of interest are low incidence populations – Practically, large numbers of subjects may not be available – Assumptions of normal distribution and homogeneity of variance may not be valid Can be used in clinical practice contexts – Single subject research studies may develop out of and be conducted on a specific problem or need of an individual(s) in a practical context • Scientist-practitioner model Dependent and independent variables Dependent variable (DV) – the behavior (measure) that you are analyzing – You want to produce change (variability) in the dependent variable – Studies may have multiple DVs Independent variable (IV) – the variable (event, intervention, condition) that is of experimental interest and that the researcher manipulates in an experimental research design – May be discrete or continuous – May be a single element or multi-component compound – Studies may have multiple IVs Internal Validity The degree to which observed differences/changes in the dependent variable are a direct result of manipulation of the independent variable, and not some other extraneous variable Extent to which a functional relation can be documented. Control of extraneous variables that provide alternative explanations for results. – It is okay to try to maximize internal validity, especially in initial documentation of a functional relationship • Doing this may come with a cost, however Threats to Internal Validity History – everything happening outside of the research study Maturation Testing - repeated measurement Instrumentation – with human observers, observer bias and drift Attrition - loss of participants Multiple treatment interference Diffusion of treatment - intervention is inadvertently provided when not intended Threats to Internal Validity (continued) Loss of baseline through generalization or spread of effects (across settings, behaviors, or participants) Instability and/or high variability of behavior – cyclical variability Statistical regression toward mean Selection biases with participants Inconsistent or inaccurate implementation of the IV (Treatment Drift/Treatment Integrity) External Validity Defined: The extent to which results can be applied to settings, activities, people, etc. other than those involved in the study. – Given that you have found an effect for this intervention with this participant under one set of conditions, will it work with other participants, in other settings, when implemented by other interventionists, and when implemented with minor variations in the basic procedures? – What can we generalize from this single study? – Importance of systematic and direct replication. Threats to External Validity Reactive experimental arrangements - Hawthorne effect Reactive assessment - reactivity to observers Pretest sensitization Experimenter bias Interaction between selection bias and treatment effects - i.e., intervention only works if the "right" participants are selected – Specificity of effects The Research Question In single subject designs the research question typically examines a causal, or “functional” relation, between the independent and dependent variable. As such the research question should have three features • Identify the dependent variable(s) • Identify the independent variable(s) • Proclaim intention to determine if change in the IV is functionally related to change in the DV. Research Question Features Dependent variable is socially important Independent variable(s) can be controlled (e.g. manipulated) across time. Both the dependent and independent variable(s) can be operationally described and measured. For “experimental” research, the question must ask if change in the DV is caused by (or functionally related to) change in the IV. Research Question Examples Is there a functional relation between development of reading fluency and scores on comprehensive reading assessments? Will walking in water facilitate development of appropriate gait by individuals with “gait imbalance hypertension.” Is there a functional relation between use of escape- extinction and reduction of escape-motivated food refusal? Does Jason act out because he has ADHD? Visual Analysis: Interaction of multiple features – Level = mean of data points within a phase – Trend = slope of best fit straight line for data within a phase – Variability = range and sd of data about the best fit straight line within a phase – Overlap = Percent of data points in intervention phase that are within the range of data in the BL. – Immediacy of effect = change in level from last 3-5 data points in BL to first 3-5 data points in intervention – Similarity of Effect = Similar effects at point of intervention (introduction or withdrawal) – Outliers = atypical data points Phase A Phase B Phase A Immediacy of Effect Level Phase B Variability Trend Overlap Research Question??? Defining Features of Multiple Baseline Designs A multiple baseline design involves three or more AB interventions (series) with phase changes staggered across at least three points in time. Key Features – Series are independent of each other • People, places, materials, behaviors/skills – The same IV is applied in each series – Staggered implementation of IV Interpreting MBL Designs – Identify Research Question(s) – Assess Baselines for each series • Do the Baselines document a predictable pattern? • Do Baselines allow opportunity to document IV effect? • Are Baselines similar? – Horizontal Analysis of Effect (per series) • Level, trend, variability, overlap, immediacy of effect – Vertical Analysis • DV change in one series is associated with NO change in other series? • Similar effect (consistent effect) across series? – Functional Relationship? • At least three demonstrations of effect at three points in time BL Lollipop for R+ Treatment 6 100 80 60 Percentage of Correct Responding 40 20 Vivian 0 Lollipop for R+ 100 80 60 40 20 Tammy 0 Lollipop for R+ 100 80 60 40 20 Dr. Cathy 0 10 20 30 40 Sessions 50 60 70 Defining features of withdrawal and reversal designs Sequential phases of data collection involving the implementation and withdrawal of an independent variable(s) – within each phase, multiple data points are collected to establish a representative pattern of behavior – phase change should occur only after stability of behavior within the phase is established – traditionally, the first phase is Baseline, followed by implementation of the IV (Intervention) • this is not required, however, as you may begin a study with an intervention phase When are reversal and withdrawal designs appropriate? Behavior measured as DV is “reversible” – Learning will not occur Limited carryover effects between phases Ethical concerns – Can do a reversal • DV is not a dangerous behavior, or you can protect participant • Staff cooperation Can compare multiple conditions – Comparison of too many conditions makes design cumbersome 4B Baseline FCT Baseline FCT 6 Total SIB per minute 5 4 3 2 1 0 1 5 10 15 Sessions 20 25 30 35 Defining Features of Changing Criterion Designs Within subject analysis Independent variable needs to have at least four levels (e.g. criteria) Document baseline performance with one level of the IV Change the level of the IV and monitor change in DV – Immediacy of change important – Absence of trend and variability important Repeat level (criterion) change in IV two more times. Example Examine the graphs below – 1. What is the research question? – 2. Is there a functional relationship? – 3.

Her scores on the Vineland Adaptive Behavior Scales were below basal levels. She has Down’s syndrome and severe mental retardation. R cannot use the toilet or eat independently and will require lifelong assistance for personal care. She is nonverbal except for some random vocalizations. R sometimes engages in aggressive behavior including spitting, and slapping Capacity-building perspective “Rebecca is a 16-year old girl with brown eyes and black hair who has been medically classified with Down’s syndrome. Her scores below basal levels on the Vineland and the Weschler Intelligence Scale support her ongoing eligibility for special education services. R is highly social and greets others using eye contact, smiles, a wave, and an occasional hug. She makes her needs known by moving to an area or obtaining materials (e.g, her bathing suit to go swimming). She can sign “eat” to request food. She has strong preferences is assertive…. Ecological Assessment: A process Method to identify instructional priorities based on a student’s current and future environments and the student’s and family’s preferences (Browder, 2001) AKA: “Functional assessment (Linehan & Brady, 1985)” “Life skills assessment (Browder, 1991)” Research on Ecological Assessment Arose out of dissatisfaction with failures in adapting standardized assessments for students with significant disabilities Information obtained had minimal impact on educational planning (Sigafoos et al., 1987; Blankenship, 1985; Cole et al., 1985) Ecological reports result in: Higher ratings of expected educational outcomes (Linehan & Brady, 1985) Educators more likely to recommend related services and less restrictive placements Steps in Ecological Assessment Process Step 1: Plan with Student & Family Step 2: Summarize what is known about the student Step 3: Encourage Self-Determination/ Assess Student Preferences Step 4: Assess student’s instructional program Step 5: Develop ecological assessment report Step 1: Plan with Student & Family Use a person-centered process Encourage student & family involvement in planning assessment & instructional goals Step 2: Summarize What is Known About the Student Summarize student’s strengths & positive attributes Use Capacity building statements (vs deficit building statements) Notes from educational records Summary of progress on IEP Goal: Describe the purpose of assessment Step 3: Encourage Student SelfDetermination/ Assess Preference Strengthen the student’s influence on their education Student may need to try new options through systematic preference assessment (Lohrmann-O’Rourke & Browder, 1998) Note student’s typical choices, talking with others who know the student, & new options Student preference enhanced by offering & honoring choices (Kern et al., 1998) Planning for Self-Determination & Quality of Life Outcomes Self-determination and Quality of Life are critical learning outcomes (Schalock, 1994; Wehmeyer, 1996). Take a look at the Arc’s Self-Determination Scale (1995). Quality of Life Planning: Home and community functioning, employment, & health and safety Step 4: Assess Student’s Instructional Program Student’s instructional program should be individualized, but should not prevent a student from participating in general education. Rather it should define how to make this participation meaningful for a student whose reading & math skills are far below grade level Developing an instructional program Begin with broad assessments, then move to specific assessments Conduct: 1. Ecological Inventory of different domains that a student experiences OR will experience 2. Conduct an activity analysis (discrepancy analysis) 3. Conduct a situational analysis/task analysis 4.Functional behavioral assessment (FBA; if needed) Start with looking at the student’s school environment In defining the LRE, start with general education…. Look at a student’s goals/objectives defined by the team and take an inventory of where in the student’s schedule those skills can be taught.

He loves music- especially reggae 2. He is a visual learner, likes puzzles, blocks, and riding bike 3. Isaac has very limited verbal language and is learning to use picture exchange communication (PECS) and sign language to communicate with others as well as picture schedules to participate in his general education classes/ activities. Isaac 4. 5. 6. 7. After you have determined where those skills can be met, conduct an ecological inventory of: Environments: (e.g., High school classes) Sub-environment: (e.g., Consumer math) Activities: (e.g., work problems in text, lecture, computer simulations, group projects, etc.) Natural supports available: (e.g., computer for each student, teacher gives 1:1 feedback Target Skills: (e.g., number recognition, use of calculator) Group Activity: Think about your current placement and outline the: Environments: (e.g., High School, Job) Sub-environments: (Classes, Locations) Activities within sub-environments: Natural supports within sub-environments: Do this for all of the sub-environments (e.g., classes, locations) a student may access in a day within your school Next, Conduct an Activity Analysis Activity Analysis Name: _______________________________ Date: _______________________________ Sub-environment/Class: _________________________ Time Classroom Activity Steps/ Natural Cues What Other Students Are Doing Target Student Performance (+/-) Comments Skills in Need of Instruction Bryant, D.P., Smith, D.

Provide sentence shell. Example: The story takes place in _________ (Chicago, Africa), have him choose the correct response to write in the blank. Collaborate with teacher to prepare a statement or response ahead of time related to reading. Provide math and word problems that are simplified, but still related to curriculum. Use coins, cubes, or other manipulatives to demonstrate concepts. Have him match numbers with actual number of objects Shorten and provide 2-choice questions to student. Use sentence shell and have student fill answers. Provide written or verbal choices to fill in blanks Have peer help him follow along with lecture. Ask him for topics to look up. If no answer, then give him a choice (age-appropriate) How student participates: Student listens and takes notes from peer/ adult. Student works on related work while teacher is lecturing Student will follow along in book. Student will find 3-4 key words. Student reviews key words and concepts after reading is completed. Identify 1-2 pictures in the classroom text and answer questions created by staff. Write correct response in blank and then recpy the sentence when complete. Uses pictures to add to his writing. Student will raise his hand and respond to a question when asked by the teacher. Have him calculate problems using calculator and/ or manipulatives, then turn in adapted assignment to teacher when complete. Have him answer simplified and/or multiple choice questions orally and then recopy or rewrite the answer. Have student use pictures to demonstrate knowledge of subject matter. He will listen to lecture and press buttons that peer directs him to. He will look up on the internet by copying address from paper on his laptop. Propose Adaptations Based on observations: Define the outcomes for the student during each activity. Are there natural supports available? Are there adaptations/modifications to the curriculum that can be made in order for the student to achieve the outcomes? Is explicit instruction on specific skills or supports needed? Plan how you will test to determine if plan is working Data collection plan What will you collect? How are you going to use the data? When do you make decisions using the data? Steps in Ecological Assessment Process Step 1: Plan with Student & Family Step 2: Summarize what is known about the student Step 3: Encourage Self-Determination/ Assess Student Preferences Step 4: Assess student’s instructional program Step 5: Develop ecological assessment report Alternative & Complementary Techniques Family’s want to do what is best for their child. May want to explore alternative therapies & techniques – Examples: medical procedures, surgeries, diets, devices, therapies Your Role Remember person-centered/familycentered planning Responsibility to educational progress Remind team of Data-based decisions/assessments Encourage use of Evidence-based practices
