M. W. Tate's 1934 typewriter studies showed student gains in language usage and spelling. Now that computers have automatic spell-checkers and students less frequently use dictionaries or study spelling in particular, does spelling ability in modern classrooms keep pace with numbers from earlier in the century when more emphasis was put on that portion of writing pedagogy?

One must wonder if the early use of typewriters to teach reading and writing research matches that of modern day use of computers and tablets in the same classrooms?
