An educational device useful in the teaching of pronunciation and spelling is disclosed. The device takes a generally planar shape and has a display window in which letters of a desired word are displayed. The letters are provided on rotatable discs, which may be three or five in number, which are individually manipulated to form the words. One of the rotatable discs bears a plurality of different visually-recognizable vowel symbols, each different vowel symbol being colored or being displayed on a colored background. The pronunciation of the vowel in the name of the color has a phonetic relationship with the desired pronunciation of the respective vowel symbol, so as to aid the student in achieving the correct pronunciation of the word displayed in the window.
