This column describes the science portion of the Ohio Graduation Test, examines some science items, and looks at instructional strategies that can be used to increase student achievement in science. ORC Science Content Specialist Terry Shiverdecker provides a thorough description of the test, including sample problems, then discusses what students will need to be able to do in order to solve those problems. A unique characteristic of the science portion of the OGT is that questions are categorized based on cognitive demand. These four categories include questions about (1) recalling/identifying accurate science; (2)communicating understanding/analyzing science information; (3) demonstrating investigative processes of science; and (4) appylying concepts/making relevant connections with science.
