Experiential / Performance-Based Learning provides opportunities for real world experiences in which the student can apply prior knowledge, create new understandings and extend his/her skills in practical ways. Students may expand upon their prior knowledge and apply what they already know. Examples include service projects, field trips, work study programs, role playing, simulations, drama, and laboratory experiments. Although performances may serve as a culminating event (such as exhibitions for senior requirements) frequently they are shorter assignments which serve as both learning and assessment. Such learning activities are typically evaluated by use of rubrics or scoring guides.
