Product Description

Product Description

Graphing calculator,

From the Manufacturer

The ClassPad 300 uses an intuitive pull-down menu interface that simplifies even complex operations. Solutions, expressions, and other items can be selected with the tap of the stylus. The calculator supports drag and drop, copy and paste, and other pen-based operations that help minimize key operations. Versatile graphing tools for 3D graphing and drawing of geometric figures provide plenty of support for the math studies of students.

The presentation application provides the teachers with tools for creating materials that promote student understanding of mathematical concepts and problem solving. The eActivity application creates eActivities that can include figures, expressions, and explanations.

The use of the stylus is easy to use.

Now Casio have replaced the Casio Classpad 300 by the Casio Classpad 300 PLUS, with a dramatically enhanced screen.

I even left the contrast setting at the default level because it is super, even for my old, tired eyes.

I purchased this Casio ClassPad 330 through Amazon and Computer Brain Inc. I ordered the calculator on November 15 and I received it on November 18 via an express carrier. I am delighted by the responsiveness of Computer Brain and their working relationship with Amazon. It's an ideal partnership that gives buyers like me a great feeling of security, and attention at a great price.
I bought the Casio 330 AFTER I already purchased the Hewlett-Packard 50G AND the Texas Instruments nSpire with TI-84 keyboard. The HP is a quality product built to the standards of their long line of calculators. The TI nSpire represents great value for the price along with a widespread user community. I kept the HP because of its external SD storage capability although it will take me a long time to master the keyboard and internal functions. I'd rather not spend the time required with the HP to master its capability. I was a former jet aircraft pilot and I like to joke that the HP is more complex than my old aircraft cockpits. Regrettably, I returned the TI nSpire/84 because the display was so dim that my eyes hurt after ten minutes of straining. When calculators like the TI have adjustments for contrast, it's really an erroneous understanding because when you increase font contrast, you also increase the contrast of the background screen which means the font does NOT improve relative to its screen background.
The Casio 330 has tremendous contrast range which actually works. I even left the contrast setting at the default level because it is super, even for my old, tired eyes. The screen has stylus touch ability that HP and TI both lack. This makes the Casio operate a lot like a Personal Digital Assistant (PDA). It's intuitive, responsive, and fun to work with.

First off, I bought this calculator more out of excitement and curiosity than need. I thought a touch screen interface would be a wonderful thing for a calculator, and the descriptions leading up to the ClassPad's release were tantalizing and exciting. To sum up, what I feel I actually have is a strange mixture of poor planning and deep insensitivity to users' needs.

The display contrast is terrible. And if you try to remedy this with a strong light source, you trade horrible contrast for double images caused by shadows. The 'screen protector' Casio provides is no help, either. It adds a reflection problem to the mix.

The huge amount of screen real estate seems like it would be a wonderful thing. Unfortunately, it is used by the calculator's OS with stunning inefficientcy. Even performing basic calculations can be frustrating. As soon as you bring up the soft keyboard, a full half of your screen is lost. Answers or problems that exceed one line are simply truncated, followed by an ellipsis and a tiny, tiny triangle you must tap to see the rest of the line. There is no way to display the whole line at the same time.

The touch screen interface, the most intriguing aspect of this calculator for me (before purchase), is very poorly implimented. The calculator has a very basic keypad for entering numbers and basic functions. It also has dedicated keys for three variables, x, y and z. Oddly, they have no keys for storing anything in these variables. The only way to do it is using the 'soft keyboard', a touch screen keyboard with several panels of keys, all of which are quite tiny and very difficult to see due to the poor display.

The LCD diplay on these units (I have purchased two, now, with the identical problem) is so bad that the units are essentially unusable. The LCD display contrast is very, very low. (it is hard to believe that the contrast is even 10:1? (a good LCD computer monitor is about 500:1))

Even under the best lighting conditions, carefully holding the instrument just so, etc. the units are hardly even readable. I have 1) replaced the batteries (both the batteries that came with the units and these replacement batteries tested fully charged) 2) carefully adjusted the contrast (being unusable is the BEST that I could get, any other contrast is hopelelly worse) 3) reset the unit, etc.

After the problem with the first unit, I looked at the Amazon.com reviews and the reviews did not mention this problem. I therefore, reasonably, assumed that this first unit was defective and so I arranged to exchange it for another one. Unfortunately, the second unit's display is equally abominable so I assume that this very unfortunate defect is intrinsic to the product.

I've used the ClassPad 330 while taking college math classes and now as a math teacher, and I'd recommend it almost without reservation to both students and teachers who are learning and teaching math. Whether it's an algebraic equation or a limit, derivative, or integral, it can solve almost any standard problem you'd see in high school math or the first year or two of a college math major sequence. (Not talking about word problems or proofs of course.) It can solve these problems symbolically or numerically and in 'math textbook form' for both input and output. The lack of standard input keys is no issue because the stylus-based touch-screen contains hundreds of math operations in logically-organized menu sections. This calculator also has powerful statistics, series/sequences, programming, standard-graphing, and 3d-graphing tools. It has a useful 'split-screen' feature where you can, for example, view your definite integral solution on the top half and the graph of that integrals area on the bottom half. Speaking of the screen, the display is clear and easy for my eyes to focus on even after spending hours solving problems in low-light conditions. While the ClassPad 330 may not be 'legal' on every math test you take, it's proven indispensable to me in studying and preparing for tests (and now creating and double-checking tests of my own). As a separate product, you can buy an emulator version (ClassPad Manager) that is very useful for teachers, as well as create activities and demonstrations for students with just the ClassPad 330 itself. One caveat though--this is for students of math and science (as well as teachers, engineers, and scientists in the working world) who want to delve deeper and perform, mathematically speaking, at their peak.Read more ›
