Indeed, since rubrics allow for widespread assessment of higher-level thinking skills, performance-based assessment is replacing or complementing more traditional modes of testing; this in turn means that teachers are changing their instructional modes to prepare their students for these tests. Kenneth Volger, in his study, “The Impact of High-Stakes, State-Mandated Student Performance Assessment on Teacher’s Instructional Practices,” analyzes the survey responses of 257 10th grade English, math, and science teachers and concludes that, since the implementation of such tests in public schools, there has been “notable increases in the use of open-response questions, creative/critical thinking questions, problem-solving activities, […] writing assignments, and inquiry/investigation.”
