 New "Classpad 300 PLUS" has enhanced screen |

| The major drawback of the Casio classpad 300 was its screen. The constrast was so poor that it was hardly usable at all.
Now Casio have replaced the Casio Classpad 300 by the Casio Classpad 300 PLUS, with a dramatically enhanced screen. The constrast is now very good under most lighting conditions. The operating system has also been enhanced, offering amongst other things a choice between the standard characters set and a bold characters set. All in all, this makes the Casio Classpad 300 PLUS one of the most powerful, integrated and easy-to-use graphing calculator ever. |
| Great pen-based calculator: Casio Classpad300 plus with OS3.0 |
| Review Date: May 9, 2007 |
| Reviewer: Ann E. Revelle, Los Alamos, New Mexico |
| I have owned numerous calculators by HP, TI, Sharp, Casio, etc., but this new Classpad 300 Plus that was just released a few weeks ago with Casio's latest operating system (OS 3.0) and Classpad Manager 3.0 is just fabulous. It is now in common use in Europe, especially in Germany and also in Australia and in New Zealand. If you purchase(d) the version with OS 2.0, you can still upgrade electronically to the newest version using the Classpad Manager Version 3.0 directly which has a number of very nice new features/functions. This calculator should also be in common use in the USA as well, but regrettably the financial dominance of TI in our marketplace (and the impending arrival of the new TI NSpire calculator) make the likelihood of its acceptance very soon quite small, unless people like myself write reviews like this to promote educators to really get involved with this new product. The real advantage of both the Classpad as well as the TI NSpire calculator (which is not a pen-based product like the Classpad) is the great software that installs on PC's so that a complete emulation of its operations is possible even without the calculator being physically available. It addition, however the Casio (OS 3.0) will do now do Dirac Delta functions, Heaviside Step functions, Fourier and Laplace Transforms (including Fast Fourier Transforms, i.e., FFT's), First order ordinary differential equations, financial analyses, and of course it already performed complex number analyses, etc.
The operating feature on the Classpad that appeals to me the most however is the pen-based drag and drop operations using the Computer Algebra System (CAS) and the interactive menu between each of the numerous types of submenus on the device. Any operation worked on in one area (Graphs and Tables for example) can readily be copied and pasted into another area (Statistics, Spreadsheets, Sequences, etc) just to name a few of the numerous possibilities. The E-activity submenu on the Casio supports presentations to an audience and is the analog for the Classpad of the TI NSpire's 4 screens of information that can all be put on to a single screen at once (analyzing a problem using a geometrical representation in the form of a drawing or a picture, a word statement of the problem, an analytic or numerical equation solution and a graph of the results). Finally, the results can all be ported back and forth and printed/stored, etc. between the Classpad Manager software/emulator and the calculator itself which is simply fantastic to use. I have had this for almost a month now and I am just begining to appreciate what it can do for me daily in my work as a scientist. If students get exposed to these devices in a late middle school curriculum and beyond (after they first master many of the basics of mathematics and science), in my opinion they will want to continue to grow into math and science in their later years and become excited leaders in science and engineering that this country has been famous for having for most of the last 60 years. |

| I just picked up the Classpad 330 and I think its great. This calculator can do way more than the ti-83 I used in the past. I like its ability to check two sides of an equation to make sure thy are equal as well as the ability to drag and drop equations into different programs to graph them or save them. I like the touch screen operation. I find it easy to use a retractable ball point pen with the tip retracted to operate the classpad. Using this method I dont even have to put down my pen to enter data I just click the pen open and closed. The spreadsheet is also nice for analyzing data. Before purchasing the classpad I downloaded the trial version of the TInspire CAS I used it for about 20 days and found it to be great software although I did not like the interface. It uses a keyboard simulator that mimics the physical keypad of the CAS so you can see how the keypad works. I saw the classpad online and decided to give it a try, I liven in a place where its hard to demo anything (except a pair of skis) so I read the reviews and although some did not like it, it seamed to be just the thing for me. If you are not good with icons it has menu operations that do the same things as the icons, though I find that all you have to do (as with any thing this complex) is read the instruction manual and it all makes perfect sense. I received a CD with computer software and a 900 page instruction manual in four languages in the box. It also comes with a paper quick start guide that attempts to give you a high altitude overview of all the functions but to really grasp all the calculator can do its best to read the manual or at least skim over the first section, I found that after reading the first section most of the operation becomes intuitive. I will say that if you don't know what you are trying to do (as far as a mathematical operation) you may be out of luck because the instructions only describe the how, not the why where or when you should use the operations. I plan on using this calculator for years and only hope Casio continues work outside the Ti box and make calculators that are not only more powerful but do more and make it easy. I now own 3 Casio calculators a fx115 from the 80s an fx300, and now the calsspad I hope to not ever have to purchase another Ti as a requirement for a class, It makes me mad that so many schools and classes require Ti products when there are superior products out there. I think ti calculators are great I have used them ti 83, 89, CAS) through the years but this is better. I have read the reviews about the screen quality and I agree with some that the screen is not the best. Im not saying that you cant see the screen but in the age where high contrast, color, backlit screens are the norm for electronic gadgets it kind of falls short of what I have become used to. Im not sure if the contrast is better on the 330 than the 300 because i have never used the 300 but on the box for the 330 one of its primary features listed in bold on the front of the box is, "high contrast display"." The contrast is high and it is easy to read but there is just something about it that makes it look kind of dim especially when compared to something like my iphone , I think its more the amount of information displayed on the screen at once it kind of begs for a backlight or a more reflective LCD surface or something. I think the best way to say it is I dont have any problems with viewing the screen but it could be improved. |
| Finally, a calculator makes it into the 21st century!! |

| Comparing the ClassPad with other calculators is like comparing Windows XP to DOS. The touch screen and slick design puts it a generation beyond all others. I could never figure out how to use my old calculator without the manual, but the Classpad is intuitive. I can enter expressions in 2D textbook form, and I can drag-and-drop math, geometry, or graphs from anywhere to anywhere. It is faster, has a larger screen, has one of the most powerful computer algebra systems available, and at a lower price than the competitors. Casio has done it again!! |

| Would you use your computer without a mouse? Would you use a PDA without a pen? If so - buy a traditional graphing calculator. If not, buy ClassPad.
I have tried to use the CAS features of high end calculators: TI 89, Casio FX 2.0 to solve real algebra problems in my work as a software engineer, but was always frustrated by the difficulty of inputting expressions. The ClassPad solves that, by its natural math input (think Word's Equation Editor). The only small fly in the ointment is the screen display - because of the need to have good battery life (and for someone used to PDA's perpetually running out of juice, ClassPad is excellent in this regard) Casio have not back lit the display, and in low lighting conditions, it can be a little dim. However, removing the protective cover helped enormously, and I'd risk a little eyestrain for the joy of using this little beauty. |
