On April 8, 2011 I shared a resource from AAAS that provided test items to measure student understanding of science and also diagnoses common misconceptions. That post made me think of some of my favorite science assessment resources- here is a mix of some online resources and two books.

• Diagnoser: an online science formative assessment tool for middle and high school students. Currently has a physical science focus, but life science is coming soon. Highly recommended!
• NAEP Released Science Items: a rich data bank of science assessment items. You can search by grade level (4,8, 12); type of question; and difficulty.
• MOSART: (Misconceptions-Oriented Standards-Based Assessment Resources for Teachers) provides K-12 assessment items in physical and Earth/Space science content areas.
• TIMSS: Trends in International Mathematics and Science Study has released math and science items for grades 4 and 8.
• PALS: Performance Assessment Links in Science has performance assessments linked to standards with supporting materials such as rubrics, student work samples, etc.
• Uncovering Student Ideas in Science Vol 1-4 by Page Keeley: Formative assessment probes for uncovering students’ initial ideas and misconceptions.
• Science Formative Assessment by Page Keeley: a book of 75 formative assessment classroom strategies

Let me know if I missed your favorite science assessment resource!
