Slide1:  Universally Designed Assessments National Center on Educational Outcomes University of Minnesota Slide2:  Goals Define 'universally designed' assessments within the current context of large-scale assessments and accountability Identify elements of universally designed assessments Universally designed assessments::  Universally designed assessments: are designed from the beginning to be accessible and valid for the widest range of students provide optimal, standard assessment conditions for the widest range of students Slide4:  Who Benefits? Universal design does not apply exclusively to people with disabilities or limited English proficiency It applies to all individuals, with wide ranging characteristics Slide5:  Think about universal design in architecture and tool design Curb cuts and ramps Elevators that talk to you Door handles rather than knobs Special pen shapes that are easier to hold Slide6:  Proposed Title I Regulations (open to comment at this time) introduce the need for universally designed assessments – [Assessments must be] designed to be accessible and valid with respect to the widest possible range of students, including students with disabilities and students with limited English proficiency. Sec. 200.2(b)(2) Slide7:  OFFICIAL BALLOT, PALM BEACH COUNTY, FLORIDA REGULAR PEOPLE GET TRIPPED UP BY THE SIMPLEST THINGS:  REGULAR PEOPLE GET TRIPPED UP BY THE SIMPLEST THINGS What’s obvious to someone who knows the answer is not always obvious to everyone. Amazon.com: Usability or Confusability?“Many of our customers have told us that Amazon.com's user interface is easy to navigate, dependable, and dedicated to ensuring prosperity. But we can do more. Inspired by the Palm Beach County, Florida, ballot form, we've devised a totally new way for you to find and discover anything you want to buy online. We've put the best possible spin on this design, and we invite you to give it a spin, too.”:  Amazon.com: Usability or Confusability?

We've put the best possible spin on this design, and we invite you to give it a spin, too.' Slide10:  Conclusion by Amazon.com:It Matters!:  Conclusion by Amazon.com: It Matters! Slide12:  Why Might We Want Universally Designed Assessments for Students with Disabilities? Current wide ranges in use of accommodations – from 8% to 84% of students in latest NCEO survey Possible misuse (over or under use) of accommodations (in some cases) Better measurement of students with disabilities Slide13:  No More Accommodations? universally designed assessments will not eliminate the need for accommodations universally designed assessments may reduce the need for accommodations universally designed assessments will reduce threats to validity and score comparability when accommodations are used Slide14:  Elements of UD Assessments Inclusive assessment population Precisely defined constructs Items developed and reviewed for bias and accessibility Amenable to accommodations Simple, clear, and intuitive instructional and procedures Slide15:  Elements of UD Assessments (continued) Maximum readability/comprehensibility Legible text Legible graphs, tables, and illustrations Legible response formats Slide16:  Inclusive Assessment Population Element #1: Universally designed assessments are responsive to: All types of students in the general curriculum A commitment to serve and be accountable for ALL students Slide17:  Inclusive Assessment Population Element #1: Universally designed assessments are responsive to: Equitable participation for all students, regardless of Cognitive ability Cultural background Slide18:  Precisely Defined Constructs Element #2: Universally designed assessments reflect good measurement qualities: Actually measure what they are intended to measure Remove all non-construct-oriented cognitive, sensory, emotional, and physical barriers Slide19:  An Example: Mathematics Tests The reading requirements of a math test often prevent students with marginal reading ability from demonstrating competency in math. Slide20:  Ordering Pizza (Original Item) The cafeteria manager surveyed the students in a middle school to find out if they would buy Brand X pizza on Friday if the manager sold it. She made a circle graph to display the results of her survey. NO YES Based on the results of the survey, answer the following questions: What fraction of students would buy Brand X pizza on Friday? What percent of students would buy Brand X pizza on Friday? There are 1200 students in this school. How many students will buy Brand X pizza on Friday if the manager’s survey is accurate? Slide21:  Ordering Pizza (Revised Item) Maria surveyed the students in her school to find out if they liked pizza on Friday. She made a circle graph to display the results of her survey. NO YES What fraction of students said 'yes'? What percent of students said 'yes'? There are 1200 students in Maria’s school. How many students said 'yes'? Slide22:  The language used in questions on tests that assess subjects other than language needs to become as 'transparent' as possible Slide23:  Bias and Accessibility Considered During Item Development and Review Element #3: Universally designed assessments incorporate accessibility as a primary dimension of test specifications Insist that item developers are trained Form Bias Review Panels that include individuals who know disability and language issues, as well as cultural, gender, and other issues Slide24:  Bias includes anything in an item that could potentially advantage or disadvantage any subgroup of examinees. It takes special thinking and review to ensure that items are not biased for each and every student who will be tested. Slide25:  Amenable to Accommodations Element #4: Universally designed assessments allow needed accommodations to be used Plan for students who continue to need accommodations Facilitate the use of accommodations such as assistive technology Slide26:  Simple, Clear, and Intuitive Instructions and Procedures Element #5: Universally designed assessments focus on the knowledge and skills assessed, not on seeing whether the student can figure out how to respond Applies regardless of experience, knowledge, language skills, or concentration level Not knowing how to respond can invalidate a student’s test score Slide27:  Maximum Readability/Comprehensibility Element #6: Universally designed assessments attend to various factors that affect readability Students’ previous experiences, achievement, and interests Features such as word and sentence difficulty, organization of materials, and format Slide28:  Sample Readability Guidelines Use simple, clear, commonly used words, eliminating any unnecessary words Clearly define any technical terms that are used Break compound complex sentences into several short sentences. State the most important ideas first Introduce one idea, fact, or process at a time Slide29:  Legible Text Element #7: Universally designed assessments use text that enables people to read quickly, effortlessly and with understanding The physical appearance of text – shapes of letters and numbers – conforms to several dimensions that characterize legible text Slide30:  Contrast – Black type on matte pastel or off-white paper produces good contrast and reduces eye strain Type Size – Print larger than 12 point increases legibility Spacing – Space between letters and between words in wide Slide31:  Leading – White space between lines of type (leading) is larger Typeface – Standard typeface, with upper and lower case letters, is better than italic, small caps, or all caps Justification – Unjustified text is easier to read, especially for poor readers Slide32:  Line Length – Text should be about 40-70 characters, or about 8-12 words per line Blank Space – Space around paragraphs and between columns of type increases legibility Slide33:  Legible Graphs, Tables, Illustrations Element #8: Universally designed assessments use non-text materials just as carefully as text materials Symbols are highly distinguishable Only essential illustrations are used (ones referred to in text and necessary to answer question) [illustrations for interest often draw attention away from construct being assessed] Slide34:  Legible Response Formats Element #9: Universally designed assessments consider the design of the response venue as well as the assessment itself Large bubbles that avoid most challenges of low vision or difficulty with fine motor skills Consideration of age of students in selecting format (avoid separate answer sheets for younger students) Slide35:  More information? Visit: www.education.umn.edu/nceo or Search for NCEO Web site includes: Topic introduction Frequently Asked Questions Online and Other Resources Slide36:  Question: Are All Universally Designed Assessments Computerized? No, universal design principles apply to all media used for assessments, including the current dominant one – pencil and paper tests. But, it may be easier to provide an array of options to students through computerized assessments. Slide37:  Computer-Based Assessments Must maintain each element of universal design Can be poorly designed and inaccessible in much the same way as paper and pencil assessments Should be used with great caution unless equity issues have been addressed Slide38:  Equity Issues Access to computers Experience using computers Training and practice with assistive technology devices and software (e.g., screen readers, speech synthesizers) Slide39:  Choice allowed by computer-based testing is a significant benefit for students – they can use the options that are most useful to them! Slide40:  Caution While universally designed assessments can make tests more equitable, producing results that are more valid for all students, they cannot replace instructional opportunity!
