OSAT Advanced Mathematics (211) case studies
OSAT Advanced Mathematics (211) · Put your knowledge to work in context.
OSAT Advanced Mathematics (211) is a subject-area certification assessment within Oklahoma's Oklahoma Subject Area Tests program. It is intended for candidates who want a teaching field in advanced secondary mathematics - the coursework above Algebra II, such as trigonometry, precalculus, calculus, and statistics - as distinct from the broader secondary mathematics field. Passing it is meant to show that you can both do the mathematics fluently and explain it in a form a high school student can follow. The test is computer-administered and multiple choice, organized around eight weighted domains: mathematical processes and problem solving, number systems and quantity, algebra and functions, geometry and measurement, trigonometry, calculus, probability and statistics, and mathematical modeling and applications. The OSAT Advanced Mathematics (211) case studies are 5 cases and about 2,329 words.
