This online Turbotest can be taken on computer or ipad using the browser. I'd like to see the final results in it. The biggest question is that if it is that predictive, why not use this sort of adaptive test for the ACTUAL SAT. It would save time and frustration.
"To create a more efficient assessment tool, Kaplan Test Prep has teamed with Testive, an adaptive test development company, to create the first-ever adaptive 90-minute practice SAT that can reliably predict a test-taker’s score level. Using computer adaptive algorithms developed at MIT and built upon decades of academic research on adaptive testing, the “Kaplan SAT TurboTest,” powered by Testive, can help students understand their current score without having to sit through a full-length 4-hour practice exam.
The first and only computer-adaptive SAT practice test, the Kaplan SAT TurboTest creates an individualized test experience for each student by adjusting the difficulty of questions as the test progresses. If a student answers a question correctly, the test difficulty level increases. If a student gets a question wrong, the test gets easier. By adapting to the test-taker’s ability, the SAT TurboTest is able to create an accurate picture of his or her predicted performance more efficiently, using fewer questions."
Kaplan has released a free SAT turbo test. In 90 minutes, they say that you'll know approximately what your score will be on the SAT. This could be something you could do with students. They've made it so you can use your web browser and take this on the ipad. I'd like to see the output that comes at the end of it.
