Validity: The questions are aligned with the AP Calculus AB standards and objectives stated at the beginning of the unit. The library was modified to include multiple choice questions, in order to more accurately reflect the AP exam. The content that is covered in the module and that has been covered in the live sessions is reflected in the unit test.
Reliability: Multiple choice questions are scored as either correct or incorrect; meaning the work students show is considered only for feedback purposes and not partial credit. Free response questions are scored using a rubric so that all students are scored the same way for each answer, depending if they have parts correct, much like an AP exam is scored.
Security: The assessment has a time limit, as all GAVS courses do. In this case it was 60 minutes for 12 questions since it was a test. The students were limited to one attempt and the question library is at least twice as big as the number of questions asked. If you view the screenshot below, the purple line between each question restricts the assessment to one question per page.
