Scientific paper

Project 2061 is creating assessment items targeting the learning goals recommended by AAAS*s Benchmarks for Science Literacy (1993) and the NRC*s National Science Education Standards (1996). One of our topics is force and motion at the middle grades level. To reduce the dependence of student performance on verbal ability, we employ graphical representations of concepts and situations. We will describe representations of (1) position versus time (Oil Drop), (2) force, speed, and change of speed (block and line arrows), (3) speed versus time (speed table). We will present sample assessment items and preliminary results from pilot testing and student interviews on comprehensibility, grade-level suitability, and effectiveness relative to purely verbal representations.
