Contingencies for the use of effective educational practices: Developing Utah’s Alternate Assessment Tim Slocum Wing Institute First Annual Summit April 2006
Main Topics • Contingencies and evidence-based special education • Designing an alternate assessment that can bring powerful NCLB contingencies to bear on promoting evidence-based special education.
Contingencies • A contingency is a relationship between behavior and consequences. • If a certain behavior occurs, then a certain consequence will occur. • Many contingencies are “natural” - that is, not intentionally constructed • Physical – Effects of jumping out of a window on falling • Social – Effects of speaking unclearly on interaction • Other contingencies are intentionally constructed to influence behavior • Parenting – Family rules • Education – Classroom motivation systems • Legislation and policy – Laws and regulations
Contingencies and Evidence-Based Practices • When we consider factors that may promote or undermine a culture of evidence-based practices, we should consider contingencies that may make such a culture more or less relevant. • What legislative and policy contingencies provide a context for evidence-based practices?
Effects of Contingencies • Contingencies can be very powerful for changing behavior. • When powerful reinforcers are given contingent on a particular desirable behavior, changes in that behavior can be dramatic. • However, if contingencies are not carefully constructed, they can produce unintended outcomes. • A teacher may offer a reward contingent on increased oral reading rate. This may result in increased oral reading rate, but also increased errors.
Contingencies – Defining Targets • There are two ways to define behaviors in a contingency: • By their form – specifying what must be done: • Examples • Study 2 hours per night… • Reading First – a federal program that specifies forms of behavior (research-based reading instruction) necessary to get a reward (funding). • This requires a specific form of behavior but leaves the outcome unspecified. • Unintended outcomes can come from completing the behavior in ways that do not produce the intended outcomes. • Consider all the ineffective “study behaviors” that a student might engage in. • Consider how mandated processes (IEP, functional analysis, implementation of research-based practices) become formalized and fail to achieve intended purposes.
Contingencies – Defining Targets • By their results – specifying what must be achieved: • Examples • Get a GPA above 3.75… • No Child Left Behind – a federal program that specifies outcomes (AYP) necessary to avoid punishment (public scorn, loss of control, loss of funding) • This specifies what is to be accomplished but leaves the process unspecified. • Unintended consequence can come from ways of producing the narrowly defined outcomes without producing the intended outcomes. • Getting a high GPA by taking easy classes • Raising test scores by excluding lower performing students.
Contingencies • So, whether we aim at what a person must do (form) or what they must accomplish (achieve), we must be very careful about defining what constitutes fulfilling the target of the contingency. • When contingencies specify difficult behaviors and promise strong consequences, the chances of unintended consequences are most serious.
Contingencies and NCLB • We can understand NCLB as a set of contingencies that specify results but leave specific forms of behavior unspecified. • NCLB has produced a lot of behavior oriented toward achieving adequate yearly progress (AYP). • Some of this behavior is desirable: • Searching for and implementing evidence-based practices, • Focus on effectively teaching core subject matter. • Some of this behavior is undesirable: • Implementing narrow test-preparation programs, • Excluding lower performing students, • Reduced focus on important outcomes that do not affect AYP.
Contingencies and Evidence-Based Practices • When we talk about promoting an evidence-based culture in special education, we must consider contingencies. • Contingencies that demand effectiveness provide a context for an evidence-based culture. • With such contingencies, many of the most serious barriers to implementation of evidence-based practices are reduced or eliminated. • In the absence of such contingencies, an evidence-based culture is likely to be less relevant. • Effective implementation of evidence-based practices requires substantial effort from many players. • In the absence of strong contingencies, this kind of effort is unlikely. • When we think about each part of the Wing model of evidence-based education, we should consider the contingencies for key actors at each point.
Contingencies and Alternate Assessment • NCLB is designed to include all students in a school’s AYP – and that is a very good thing. • Given the strength of NCLB’s contingencies, behavior that is not relevant to meeting its demands is likely to be reduced in value. • Exclusion from contributing to AYP does not just imply avoiding the pain and hassle of test-taking. • Exclusion makes the student’s educational progress irrelevant to the powerful contingencies of NCLB. • Those who are not counted, don’t count. • NCLB includes a provision specifying that students with significant cognitive disabilities (SCD) take an alternate assessment that will contribute to AYP.
Utah’s Alternate Assessment • We (Karen Hager and I) became interested in whether an alternate assessment could be constructed that would take advantage of the strong contingencies of NCLB to: • motivate effective educational practices and • improve educational outcomes of students with SCD. • We worked with the State of Utah to attempt to construct an effective alternate assessment. • We realized that validity of the alternate assessment would be critical. • Validity is a technical term for the degree to which an assessment successfully accomplishes the purposes for which it is being used. • Validity is critical for producing intended outcomes and avoiding unintended outcomes from contingencies.
Importance of Validity • The contingency of NCLB is based on test scores, not important student learning per se. • To the degree that alternate assessment results are valid, the contingencies of NCLB could have very positive impacts. • To the degree that alternate assessment results are invalid, the contingencies of NCLB could be very detrimental.
Defining the Construct We began with the question, “What are we trying to measure?” • Federal mandate – AA must assess: • Domains of Language Arts and Math forstudents with SCD. • Our values – AA should assess: • Skills that will contribute to independence and effectiveness of students with SCD. • The construct that drove the development of Utah’s Alternate Assessment: • Language Arts and Math skills that will contribute to students’ independence and effectiveness for students with SCD.
Sources of Invalidity • There are 2 main sources of invalidity: • Construct-Irrelevant Variance – the assessment may be influenced by factors that are not part of the target construct. • May result in strengthening the wrong behaviors. • Construct Under-representation – the assessment may ignore some important component of the construct. • May result in failing to strengthen some appropriate behaviors.
Construct Irrelevant Variance • Sources of Construct Irrelevant Variance • Direct assessment of factors other than student behavior • E.g., degree of inclusion, attendance, and other issues • Assessment of skills in such a way that outcomes are heavily influenced by how the teacher documents student behavior. • E.g., some forms of portfolio assessment • Inclusion of skills that are not important. • E.g., academic skills that are not functional • Problems with administration • E.g., Low fidelity of implementation and low reliability • Trivial tasks • E.g., assessments on which all students will be “proficient” no matter what their skills.
Construct Irrelevant Variance • Implications of Construct Irrelevant Variance • These are sources of unintended effects of the contingency • The contingency may strengthen behaviors relevant to these other factors at the expense of actually improving the learning of important skills.
Construct Under-representation • Sources of construct under-representation • Some important skills are not assessed. • E.g., actual differences in critical communication skills do not impact test results • Implications of under-representation • The powerful contingencies of NCLB may reduce focus on these important skills.
Construct Under-representation • NCLB appears to be very powerful in changing behavior of teachers and administrators. • If this power is to benefit students with significant cognitive disabilities, Alternate Assessments must be highly valid. • That is, they must reflect actual student performance on important tasks and must exclude other factors as much as possible.
Standardization among diversity • The greatest challenge in designing an alternate assessment is to: • Produce meaningful, standardized outcomes • For a highly diverse group of students. • This requires a balance of standardization and individualization.
Standardization in UAA • Standardization is necessary to enable those not directly involved in the administration to interpret scores. • Standardized bank of tasks • UAA includes approximately 115 tasks in language arts and math • Standardized administration procedures • Each task requires direct observations of student performance • Tasks are to be embedded in naturally occurring routines in natural settings • Any communication system or assistive technology the student typically uses is acceptable during the assessment
Standardization in UAA • Performance criteria standardized for each task: • Performance criteria are designed to reflect a “functional” level of performance, i.e., a level that makes the skill meaningful/useful • Students perform the task independently (e.g., no physical, verbal, or gesture assistance) • Measurement tasks specify assessment of generalization: Three performances in situations that vary in relevant variables (e.g., people, settings, materials)
Individualization in UAA • Individualization is necessary to ensure relevance to specific students. • IEP team selects targets from list of standardized tasks • IEP team selects content on some tasks • E.g., specific sight words to be assessed
Individualization in UAA • IEP team adapts the task to some individual circumstances • IEP team specifies the natural routine during which to assess • IEP team selects appropriate generalization settings • E.g., particular individuals, settings, materials
Defining Adequate Yearly Progress • AYP for general education students • Standards set by grade level • AYP for students with SCD • Grade level not relevant basis for defining standards • Tasks that define AYP must be identified individually. • In UAA, IEP team selects relevant tasks from task bank. • Given a relevant task, performance level necessary to declare AYP is standardized.
