The Casio ClassPad 300, ClassPad 330 and fx-CP400〔http://www.casio-intl.com/asia-mea/en/news/2012/fx-cp400/〕 are stylus based touch-screen graphing calculators. The ClassPad comes with a collection of applications that support self-study, like 3D Graph, Geometry, eActivity, Spreadsheet, etc. A large 160x240 pixel LCD touch screen enables stylus-based operation. The ClassPad resembles Casio's earlier Pocket Viewer line. HP and Texas Instruments attempted to release similar pen based calculators (the HP Xpander and (PET Project ) (see TI PLT SHH1), but both were cancelled before release to the market. The ClassPad 300 allows input of expressions, and displays them as they appear in a textbook. Factorization of expressions, calculation of limit values of functions, and other operations can be performed while viewing the results on a large LCD screen. The ClassPad 300 comes with graphing tools for 3D graphing and drawing of geometric figures. The user interface of the ClassPad 300 uses a pull-down menu format. Solutions, expressions, and other items can be selected with the tap of the stylus. The ClassPad 300 also supports drag and drop, copy and paste, and other pen-based operations. An eActivity application allows the creation of eActivities that can include figures, expressions, and explanations. In the United States the ClassPad series is banned from standardized tests including the SAT, the ACT, and the AP Calculus test.〔(Ban from SAT, ACT and AP Calculus tests. )〕 ==History== During 1996, CASIO worked on the CAS (Computer Algebra System) and studying Geometry. The CAS was first used in the Casio CFX-9970G then the Casio Algebra FX 2.0, and later formed the core math system for the ClassPad. In 1999, with the help of many teachers and friends, the idea of the eActivity emerged. It would allow all applications to interact from within one application, and display information in a textbook style. In 2000 CASIO opened a new office, the CASIO Education Technology M.R.D. Center in Portland, Oregon, USA. They hired engineers familiar with programming PCs and specialists from the education field. Ideas from around the world were now being implemented into the ClassPad by Tokyo R&D and Portland MRD Team. In 2002 CASIO completed a prototype for the ClassPad. Before the prototype was complete, an emulator was used for testing. The emulator was so good that CASIO decided to include the emulator in the software that was being developed for data transfer. The data transfer and emulator software merged into one product called the ClassPad Manager. In 2003 CASIO released their first product: the ClassPad 300, with 4.5 MB of flash memory. In 2005 CASIO released the ClassPad 300 Plus featuring 5.4 MB of flash memory, a higher-contrast display and standardized Mini-USB port. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Casio ClassPad 300」の詳細全文を読む スポンサード リンク
