TI-84 to TI-89 conversion

[Nicole Lang]

Hello, everyone.

My department recently discovered this ad on Craig's List:  http://minneapolis.craigslist.org/ram/ele/4100760263.html

In case the link disappears, the student has somehow modified the operating system of his TI-84 to make it into a TI-89 in disguise.  Furthermore, he has many extra calculus programs AND something that will (apparently) show you all the steps for getting to the answer.  I took the liberty of downloading his YouTube demonstration video (just in case that disappears from his YouTube channel).  Here's my copy of his demo:  http://youtu.be/zuoXj0Oen-o 

We know that this person is a current student in one of our calc classes, since his instructor has informed us of that fact.

So... have any of you heard about such a creation (the TI-89 in disguise)?

Do you have any thoughts about how to deal with this "new" technology?  (We have many faculty members who allow the TI-84 but not the TI-89, so that's a big issue here.)

Thanks in advance for your thoughts and advice!

I once had a student with TI89 that had a face plate from a TI84. There are directions online for doing this. http://www.wikihow.com/Make-a-Frankenstein-89-Graphing-Calculator-from-a-Ti-83-%26-Ti-89

Now if he had only put all that energy to use in studying rather than cheating...  I don't think some of them see the difference.

 

Very eye-opening.

Good to know.  This is a software change.  I'd guess the student either has really smart friends or is buying this somewhere else.

I had a student this summer wanting to use a new kind of Inspire. After a quick google search I told him no.  You can store pdf notes on it, and according to one of our adjuncts who is also a high school teacher, it does a lot more than just store pdf notes.

We do not allow our students to use anything above the TI-84 because the others can be programmed or store programs that will derive the solution to most problems through calculus. I guess if we make our students write proofs for all of the problems we “may” not have to worry about this J

[Jackson, Sharon]

Wow okay I just read this again. So this student had a TI-84 and uploaded programs to make it operate like a TI-89? Wow! I will have to bring this to the attention of our workgroup because we don’t allow our students to use the TI-89, 92 or nspire for this very reason.

It's worse than just having the capabilities of the TI-89.  It also has program(s) that will "show work."  If you watch the YouTube demonstration, at about the 3:30 mark, the student demonstrates how the program will show you the steps (u, dv, v, du, etc.) for an integration by parts problem (plus the answer, of course).  If I had $260 to blow, I'd get someone to buy a calculator from this student just so I could see what all it does.  I'm upset, but not motivated enough to cough up $260.

It does boggle the mind, though, how much effort our students will put into cheating when it probably would be easier to study.  :)

I thought I should point this out:

ANY TI-84 has a an app pre-installed called ZOOM4MATH that will show steps to algebra problems through calculus problems... Press the 'App' button and check for yourself.  I still can't figure out how to use the program, but it's there...
