Abstract
Abstract A machine for teaching students to read is equipped with a visual display, a manual keyboard for entering alphabet letter responses, correctness and incorrectness indicators of display responses, and conditioning means for initiating particular grammar characteristic sequences to be practiced. The machine also includes a repertoire of words and letter combinations corresponding to word roots encoded in an electronic form and stored in digital memory. A word set is assembled in response to an instruction from the conditioning means concerning the grammar characteristic sequence to be practiced. Words or word roots are selected at random from the assembled word set for display or partial display. The student, through the keyboard, is thereby able to identify particular vowels and consonants, long and short vowel sounds, soft and hard consonant sounds, determine the number of syllables in a word, identify misspelled words, supply missing letters, and identify words as to their grammatical parts of speech. The correctness and incorrectness indicators inform the student as to the accuracy of the manually entered response.

Apparatus according to claim 4 further characterized in that said means for applying tests includes means for determining syllable demarkations within a word appearing on said display means and means for altering said image of a displayed word by increasing spacing of letters thereof between adjacent syllables upon depression of a switch in said keyboard means.
Claim 7
Dependent Claim
81 words
Apparatus according to claim 1 further comprising means for suppressing generation of the image of at least one letter in a word appearing on said display and means for storing an electronically encoded form of a letter so suppressed, and further characterized in that said keyboard means also includes switches that correspond to electronically encoded letters of the alphabet, whereby depression of such a switch to supply a missing letter of a word provides a signal to one of said indicators.
