The following paragraph is taken from a message posted by Deanna De'Liberto. My comments follow.
"But this is not likely to happen if the TI-92 is not permitted on the exam. And, I should point out that the ONLY reason it is NOT permitted on the exam is because it has a QUERTY keyboard, and NOT because ETS determined that it was not an appropriate calculator or would provide some students with an unfair advantage or the like. The decison NOT to permit it was made solely for test security reasons." --------------------------------- The statement above is NOT ACCURATE. Although test security is an issue that concerns both ETS and the College Board (and it will always be an issue), that is NOT the main reason that the TI-92 is currently unacceptable for the AP Calculus Examinations.
To quote directly from the May 1998, May 1999 AP Calculus Course Description: "There are two main concerns that the committee (i.e., the AP Calculus Development Committee) considers when deciding what level of technology should be required for the examinations: equity issues and teacher development. The committee can develop examinations that are appropriate for any given level of technology, but it cannot develop examinations that are fair to all students if the spread in the capabilities of the technology is too wide. The use of graphing calculators is a recent change for the program, as is this new course description for the 1997-98 academic year. The AP Calculus Development Committee recognizes that these changes place a large burden on AP teachers, who need time to incorporate these changes into their courses. The committee will continue to monitor the developments of technology and will reassess the testing policy. Examination restrictions should not be interpreted as restrictions on classroom activities."
