93 immigrants in south Florida, McCoy and Gonzalez (1982) suggest it is necessary to look at the contributions already made by Cuban-Americans and other Latin groups who have made their homes here. After all, McCoy and Gonzalez say, "less than one-third of present residents have claims to being native Floridians" (p. 36). Educational Comparison Rivero's work (1981) is the only research to be found that deals specifically with 1980 Cuban teenagers in U.S. schools. Rivero finds that most of the youth he surveyed indicate the U.S. schools are stricter than most Cuban schools. The teachers of these children report the children display somewhat unruly behavior in that they have difficulty taking turns in talking and listening when others speak. In contrast, these students report the level of difficulty of the material presented was greater in Cuba, even though there are more exams and homework here. According to Rivero, many of the Cuban students appear to have poor preparation in Spanish language, especially grammar, but are taking advanced mathematics and sciences. Rivero (1981) says, "Their weakness in their native language may make the learning of English even harder for these students. This fact, along with their apparent ability in math, argues for a greater emphasis on teaching them communication skills" (p. 9). Even though this group displays many outward symbols of acculturation, Rivero expresses concern about their understanding of basic work values. Students avoid being labeled as coming from Marie!, with a disproportionate number listing Spain, or Costa Rica, or other countries as location of origin before entering the U.S.
