84 vs Nspire

[rebe...@gmail.com]

What would you tell parents as to why they should purchase the Nspire
over the 84?

[Michael Houston]

The 84 has reached its potential.  The nspire is designed in such a way that as technology changes, it can change too.  The nspire works more like a computer than a calculator.  Textbooks and resources are now being written for the nspire.
 
The nspire is a document based calculator, so as students work through problems the npsire can "follow" their thinking and ideas.  Let's say they get stuck.  They can email me the file they've created and I can answer their question on the fly...
 
I usually keep things simple when talking to parents.

Wow, I have so much I want to say on that topic. I was just working on a future blog entry on this topic

For most of the following it would be nice to give additional explanation to but I'll start a summary list.
1. The TI-Nspire now comes with the Student Software.
2. Math Print is native (some programs on the 84 don't work unless the mode on the 84 is changed back to the 'classic').  – looks like what is on students’ paper or textbook
3. Dynamic relation between environments
4. Resolution
5. It even has grayscale (color on the software)
6. Geometry is integrated. Dynamic geometry in the hands of students!
7. Animation

8a. TI-Nspire (not Nspire CAS) comes with TI-84 keypad - 2 for the price of 1.
b. CAS has units – great for science
CAS has exploration & discovery possibilities in algebra

9. Notes - makes it so much more pedagogical.
This really is a learning (& teaching) tool.
NEW - Interactive Notes make this dynamic too.

10. History preserved. It is better than an 84 (which is somewhat better with 84 OS 2.53MP)
which only has a history of 10 that many of my
students didn't even know existed. History of 99
for each page (50 pages max) in each of the 30
problems allowed in a single document.
11. INEQUALITIES
12. TRANSORMATIONS
13. no more false asymptotes
14. Graph function, polar, parametric, implicit on the same screen.
15. sliders
16. Incredibly easy to use data collection
17. Many inquiry activities have been written.

If I were a parent I would check with my child's teacher and school to
determine the best device to purchase. This goes for computers, too. You do
want to be compatible with school if it's going to be used for schoolwork.
Admittedly, computers are more compatible now than ever before.

I know that the TI-Nspire is a much better unit than the TI-84 for all the
reasons others have so clearly listed (and more), but the biggest issue is
how well the device will work in school. Will the teacher allow and support
the use of one TI-Nspire in her class?

Finally, why not TI-Nspire CAS?

Students should at least have the TI Nspire. It is 2 calculators for
the price of one. I am having my students get the cas version but that
only has the one faceplate and many teachers may not allow it. The 84
and Nspire are the same cost. If they already have an 83 or 84 they
will be fine- no need to buy a new calculator.

They are not selling the CAS in retail stores. Yyou can get them on
Amazon or my personal preference is Calculators Inc in Richfield, mn.
Call them and
Mention my name and they will get you your best price.

I use Underwood Distributing in Michigan: mil...@underwooddist.com Miles Underwood is great to work with as a school. Buying twenty or more gets you a really good price and usually avoids any shipping charges or sales tax. My students bring in checks made out to our Math Club and we place the order through ASB. And I agree, Amazon is always worth checking--they sometimes have great prices and almost always do better than Best Buy, etc.

There are two reasons why my school uses Nspire not Nspire CAS:
1. we are an IB school and IB, like the ACT, does not allow CAS on their exams.
2. the interchangeable 84 keypad. a few of my teachers are a little slower to get on board with the Nspire so this way the student has both.

Also, if you are in BC, Canada, the Math provincial exams currently
state that the Nspire can only be used with the 84 faceplate. And the
Science provincials do not allow graphing calculators at all. So that's
why I wouldn't recommend the CAS.
