Mathematics Subject Test Selection

13

• Students who have taken trigonometry and/or precalculus and received grades of B (or better) should probably select Math Level 2.

Consider taking the test that covers topics learned most recently (when content is fresh in the student’s mind).

Consider the requirements of the colleges and/or programs in which students are interested.

• Students who are sufficiently prepared to take Math Level 2 but take Level 1 in hopes of receiving a higher score may not do as well as they expect to.

• Students who have taken trigonometry and/or precalculus and received grades of B (or better) should probably select Math Level 2.

College-level tests that assess a student’s knowledge, skills and

SAT Subject Tests can also provide students without access to certain AP classes the

opportunity to demonstrate subject-matter achievement.

The Timing of AP® Exams and SAT Subject Tests™ Makes a Difference

15

• Timing – SAT Subject Tests provide AP students who have not yet taken the AP Exam an opportunity to demonstrate knowledge and achievement during the admission process.

• Most students do not take any AP math course until their senior year; AP Exams are in May.• Subject Tests in Mathematics are offered six times a year and can be taken by students in

any grade.

SAT Now on a School Day

• Two SAT School Day test dates in 2011-12 in selected districts and states.

• Administering the test on a school day eliminates barriers of

transportationfamily work obligations

that may hinder weekend testing, helping to get even more students on the road to college.

Increasing Access: State Initiatives, Fee Waivers

States providing/paying for SAT• Maine administers May SAT to all public school juniors• Texas pays SAT fees for any junior for any test date• Delaware administers school-day SAT to all juniors, as will Idaho

Fee Waivers• More than just the waiver of test fees — low-income students get

access to a set of tools that help them realize their college dreams.• Over 350,000 low-income students (21% of all SAT-takers) in the

class of 2011 benefitted from SAT Fee Waiver Services, a 77% increase since 2007

• Over $37 million in SAT fees and services provided to students in grades 9 – 12 during 2010-11 school year.

The SAT Mathematics Development Committee

College Board Committees

• A Committee in the early 1990s advised the College Board on 1994 changes to the SAT.

• A Committee formed in 2002 to advise the College Board on introducing changes to the SAT.

• The present Committee continues to advise the College Board on the SAT.

Committee Decisions

• The SAT should remain a reasoning test. • There will not be a no-calculator section of

the SAT.• Students should be able to bring the

calculator they use in their classroom.• Questions admitting multiple solution

strategies (including those involving the calculator) are encouraged.

• Questions involving multiple representations of material are encouraged.

What is the Calculator Policy for the SAT?

The Calculator Policy

• Every question on these tests can be solved without a calculator; however, using a calculator on some questions may be helpful to students. A scientific or graphing calculator is recommended.

• Calculator use is permitted on all sections of the SAT Mathematics test.

• Most calculators are permitted, including those with (CAS) computer algebra systems.

The Calculator/Equity Issue

• The SAT Mathematics test contains questions requiring students to simplify algebraic expressions or to solve equations.

• Students can do this algebra “by hand.”• Students who have and can use a calculator

equipped with CAS (computer algebra system) may be able do this algebra by “pushing buttons.”

What is the Calculator/Equity

Study ?

Questions to be Answered

• What effect, if any, does CAS have on mathematics performance on the SAT?

• What models of calculators are students using on the SAT?

• How are students using their calculators on the SAT?

• Do students who have calculators with CAS have an advantage?

The Study Design

• A short survey at the end of one SAT administration to be answered by all students at that administration

• Two specially designed variable sections, each given to a subset of students at the administration; one pretest contains 6 CAS-active questions; the other contains 6 algebra questions of comparable difficulty

The Study Design

Survey questions:• What calculator did you use on the

Mathematics sections of the test?• Is this the calculator that you use in your

classroom?• How did you use your calculator?
