Learning Outcomes • • Explain need and purpose of assessment Describe characteristics of norm-referenced, criterion-referenced, and curriculum-based assessments • Describe limitations to traditional and formal assessments for young children • Describe advantages of alternative assessments for young children * Key concepts for Exam III HD FS 340 Assessment & Program Planning November 5, 2002 Susan Hegland, Ph. D. 1 Why assess? 2 Screening • Assessment is the process of • To identify children who may be at risk for health or developmental problems • To determine whether child’s performance is sufficiently different from others to warrant indepth diagnostic assessment • Occurs prior to other measurement processes • Brief and easy to administer – observing, – gathering – recording information • Purpose: to make evaluative decisions – Screening – Diagnostic assessment – Program assessment – Program evaluation – Facilitates administration to large groups • Norm-referenced 3 Diagnostic assessment 4 Program assessment • Purpose • To determine child’s current skill level • Guides program planning and implementation • Document children’s progress over time • Criterion-referenced or curriculum-based assessment – To determine whether a problem exists – To identify the nature of the problem – To conclude whether child is eligible for services under IDEA • Highly specialized and in-depth – Administered by trained professionals (e.g., Master’s level school psychologists) • Used for referral and placement decisions • Norm-referenced 5 6 1 Program evaluation Formal assessments • Program evaluation (accountability): • Predefined, highly structured tasks – Input • Resources (dollars & staff time put in to program) – Specified guidelines for administration – Output • Focus on isolated aspects of development • Quantity & quality of services provided to clients – Outcomes (Results) – Easy to observe – Easy to measure • Changes in clients (e.g., children, parents) as a result of services received • Required by most funding sources of educational and human services • Child Outcome Evaluation • Norm-referenced – based on a standardization sample – To determine how children progress over time by comparing child’s skills before and after intervention – Criterion-referenced or curriculum-based assessments • Includes standardized tests (e.g., ACT, ITBS, Bayley ) 7 8 Norm-referenced Assessment Criterion-referenced assessment • Provides information on how a child is developing in relation to a larger group of children of the same chronological age • Items chosen according to strict criteria: – Percentage of children who master skill at certain age – Does passing item predict getting a high score? – Does failing item predict a low score? • Test must have – reliability (stable) • High test-retest agreement • High agreement among items – validity (accurate) for the • Measures mastery of specific objectives defined by predetermined standards of criteria • Items usually sequentially arranged within the developmental domains or subject areas • Numerical scores represent proportion of specific domain or subject area that a child has mastered • Typically: isolated items chosen from normreferenced tests (e.g., Brigance, Denver) • Purpose intended • Population (e.g., Spanish-speaking?) 9 10 Limits to traditional assessments Curriculum-based assessments • Form of criterion-referenced assessments • • • • – Program objectives guide item selection • Curriculum-referenced assessments – California Desired Results Developmental Profile • Curriculum-embedded assessments Underestimate young children’s skills Lack relation to program goals Do not permit adaptation to context or culture Do not take into account child’s response to instruction – – – – – – – – AEPS (Assessment, Evaluation, & Programming System) – Creative Curriculum Developmental Continuum – High Scope Child Observation Record (COR) • Portfolio assessments 11 Child points to milk Adult: what do you want? Child: no response Adult: do you want milk or bread? Child: “mihl” Adult: “You want milk? Child: “Milk!” 12 2 Advantages of alternative assessments HD FS 340 & assessments • Screening assessments • Curriculum based Assessments • Focus on whole child • Focus on natural context • Monitor response to instruction (scaffolding) • Linked to curriculum – Naturalistic assessments – Focused assessments – Dynamic assessments – Curriculum-based language assessments – Transdisciplinary models 13 14 Intervention/Teaching/Curriculum Strategies Why curriculum-based assessments? 1. Structuring physical space & materials 2. Using children’s preferences for materials & activities 3. Structuring social aspects of environment 4. Structuring routines 5. Using structured social activities 6. Using different reinforcement strategies • High adult 7. Using response-prompting control strategies • Low adult control Your professional role: For each child you work with, decide when to • watch child “construct”, develop, acquire skill/knowledge • “teach” or “intervene” to help child acquire skill • Which skills? • When? • How powerful adult strategy to use? 15 When to use high adult control to intervene to develop child’s skill? 16 Think of a child… For whom the following tasks are – individually appropriate – require low adult power: • When probability of child initiating skill on own is LOW • When probability of adult control strategy producing specific child behavior is HIGH • • • • Uses words to get help from adults Shows beginning of impulse regulation Counts to two or three Can be distracted from unsafe behavior with verbal limits • Learns and uses new vocabulary in everyday experiences Repeat for high adult power… 17 18 3 Think of an infant/toddler you know with “challenging” behaviors… Level of Adult Power used to elicit behavior High Low Probability of child-initiated behavior Low High Model of assessment & intervention 19 Use the California Desired Results Dev’tal Profile: • Think of a skill that you DON’T need to facilitate, – because the probability of the child initiating it on her/his own is high… – OR because the probability of anything you do producing it is low… • Now think of a skill that you DO need to facilitate, – because the probability of the child initiating it on her/his own is low… – OR because the probability of anything you do producing it is high… • Share these with your learning team; choose one to share with large group 20 How can curriculum-based assessment help you? Identifies: • what the child is currently initiating • important target skills to work on • what you can elicit with a variety of low to high adult control strategies • context in which intervention is likely to be successful 21 4
