Correct Response: B. An authentic assessment is an assessment that is based on observing students as they engage in authentic learning tasks tied to a specific curricular goal or objective. In this case, students have an opportunity to create their own displays to demonstrate their understanding of physical properties of matter. This assessment is also multidimensional because students not only have an opportunity to demonstrate their understanding of relevant content through the creation of a display but also by orally describing their display. A is incorrect because a formal, quantifiable assessment is a standardized test (typically multiple-choice) that summarizes a student's performance numerically (e.g., as percent correct). In this case, the teacher's use of notes does not result in a quantifiable (number- based) result. C is incorrect because a global, comprehensive assessment is one that evaluates students' performance across content areas. In this scenario, the assessment is focused on evaluating students' performance with respect to a single science objective. D is incorrect because the assessment described in the scenario is not standardized. A standardized test is a test that has specific tasks and procedures that must be followed exactly. In this case, students have some flexibility in demonstrating their understanding of target content.
