Peer reviewedGraviss, Tom; Greaver, Joanne – Mathematics Teacher, 1992
Shares a coded version of the number line to provide concrete experiences for learning abstract concepts. Using the fundamental theorem of arithmetic, appropriate coded symbols are determined for the prime factorization of each natural number and used to study the concepts of greatest common divisor, least common multiple, square roots, and…

Peer reviewedSparks, Richard; And Others – Annals of Dyslexia, 1989
A theoretical framework is presented for understanding difficulties in foreign language learning, based upon a linguistic coding model that hypothesizes deficits in phonological, syntactic, and semantic information processing. Incidence of linguistic coding problems in 22 college-enrolled or college-bound students who petitioned to have the…
