Professional Commentary
Students are asked to review data that is presented in a table and from the data determine which of the three minerals can scratch the other minerals. Students are also asked to explain their answer. This constructed response question is a sample test item used in past National Assessments of Educational Progress (see About NAEP). The URL link above takes the user to the NAEP test item, with access to performance data by various subgroups, a scoring guide and student responses, and the content on which the item is based. The NAEP web site allows users to build their own printable database of test items by clicking on Add Question in the upper right hand corner of the screen. NAEP Reference Number: 2005-4S14 No.: 11.
