CONSTRUCTing Effective Assessment Questions using the NGSS DCIs

Saturday, October 28 • 11:30 AM - 1:00 PM

Kansas City Convention Center - Exhibit Hall, Share-a-thon Area


Show Details

Using the Disciplinary Core Ideas and a research-based “citizen science” approach, science educators contributed their own test items, and helped to revise existing test items in order to address crucial issues such as difficulty, gender, and racial/ethnic bias that were present in the item analysis characteristics. We share the analysis and results of these efforts so that educators can assess their own test items to be more inclusive of all students’ understandings in one of the dimensions of the 3D-approach to learning. Learn what changes contributed to improvement of the item as well as what types of changes or revisions made the item worse than before. We also share results of field testing of these items in student classrooms and discuss the importance of incorporating students’ misconceptions into the response choices to capture their true understanding of science concepts as outlined in the DCIs.

Learn to evaluate assessment questions that you use to assess students’ sensemaking of elements outlined in the NGSS DCIs. Are the questions free of bias, not too difficult, indicative of overall student performance? Do they include common misconceptions that students hold? Utilize a free resource.
