  2. So what about those distractors? • Distractors are designed to distract students, hopefully those with less ability. • Distractors tend to be fillers, to occupy the other three or four options. • Distractors are sometimes absurd or even humorous. • “It’s hard to write 3 or 4 good distractors!” • Distractors are usually not attractors.

  3. Item Response Attractors • Attractors attract students with specific misconceptions or reasoning errors. • Attractors focus attention on attracting the right students – those with lower ability. • Attractors require the incorrect options to be plausible, yet not the best answer. • Attractors are not filler options.

  4. Item Response Attractors • Attractors contribute to the overall quality of the item and test. • Attractors play a central role in determining the difficulty of an item. • Attractors are explicitly designed to inform us about prevailing misconceptions and errors. • Attractors are explicitly intentional. • Attractors are explicit.

  5. To be Consistent We are compiling evidence from our own work and the work of others regarding the utility of being direct and explicit in our item writing, relying on good item writing guidelines, elements of Universal Design, concepts from Cognitive Load Theory, and research based on language complexity and accessibility for diverse students. TAMI provides a systematic guide.

  7. 1. What is the most effective method to reduce the internal air temperature of a house in a humid subtropical climate? • Fan • Evaporative cooler • Air conditioner • Dehumidifier • 2. What is the most effective way to cool a home in a humid climate? • Air conditioner • Evaporative cooler • Fan

  8. Effects of Item Modification • Item Difficulty • Item Discrimination • Attractor Functioning

  9. Change in Attractor Discrimination

  10. Change in Attractor Response Rates

  11. Attention to Attractors • What makes this option an attractor? • Is this an effective attractor? • How many attractors are needed? • How can we improve the effectiveness of the item attractors? • Does a focus on attractors rather than distractors matter? Does it help us make items and tests more widely accessible?
