[Blindmath] Techniques for taking Algebra through Calculus?

Tue Mar 1 05:05:47 UTC 2016

No not all TI calculators are CAS devices. There are actually cas versions of TI-84 and Nspire but not all of them are CAS based.  For example if you do an derivative or integral or even square roots on TI-84 without a special program on the TI-84 you get a number not a text answer.  The cas system would give you the reduced text answer not a number.  See this page:

Just to clarify, I’m suggesting that a student who is blind write their work using CAS markup. Regarding standard tests… It is true a student can not use a programable or graphing calculator on ACT, SAT, and GRE. The mathematics level of the GRE is actually lower than the ACT and SAT. My understanding is that it is far less reliable that a student has taken a math class within the last 3 years and as such the work does not go beyond College Algebra/Algebra 2. 

However, I think a TI-80 or higher calculator would be considered a CAS device, which is allowed on AP exams these days. They weren’t when I took my Calculus AP, and I was rather indignant when I found out they are! I’d draw your attention to the below quote found at: https://apstudent.collegeboard.org/apcourse/ap-calculus-ab/calculator-policy

"Calculator memories will not be cleared. Students are allowed to bring to the exam calculators containing whatever programs they want. Students must not use calculator memories to take test materials out of the room. Students that attempt to remove test materials from the room by any method will have their exam grades invalidated."
