This pamphlet presents the content of a workshop on the contrastive analysis of Spanish and English sounds which create pronunciation difficulties for Mexican- American children learning the English language. Introductory remarks lead to teaching procedures for: (1) "ch" (voiceless alveo-palatal affricate, (2) "sh" (voiceless alveo-palatal fricative, (3) contrast of "ch" and "sh" (4) "th" (voiceless dental fricative, (5) "th" (voiced dental fricative, (6) initial "d," medial position "d", and final "ed" (voiced alveolar stop /d/), (7) final "d" (voiced alveolar stop /d/), (8) final "ng" (voiced velar nasal), (9) "z" (voiced alveolar fricative /z/), (10) short "i," and (11) "y" (voiced alveo-palatal resonant semiconsonant /Y/). Suggested games and practice drills are included. A selected bibliography concludes the text. (RL)
