In this study we document how a mathematical idea, shared by a student, changes the development of the class discussion. Our work characterizes the flexible and open dynamics in mathematics instruction that a teacher adopts to give her students control of their own mathematical ideas. Our work argues that this flexibility is necessary for teachers…

Seventeen Spanish-speaking children received mathematics instruction in either Spanish or English. Numeric concepts were chosen as the content area so that the results could be understood non-verbally at the outset, the teachers ranked the children's abilities in English and math, and no significant difference between groups was found. However,…

A study investigated the characteristics of elementary school (kindergarten and grades 1-2) teachers of limited-English-proficient (LEP) students and the oral language proficiency of students in the classrooms of identified effective bilingual and English-as-a-Second-Language (ESL) teachers. The study involved (1) a district-wide survey of…

A study investigated spelling error patterns in native Spanish-speaking students of English as a Second Language to determine the degree to which errors can be attributed to phonological patterns. Specifically, it examined (1) which spellings can be attributed to differences in voicedness of consonants, and (2) whether the voicedness can be used…

A study compared language skill development and cultural attitudes of second-grade children taught in an additive-bilingual program setting with those of second-grade children from a monolingual classroom setting. Subjects were 41 second-grade children participating in a Spanish immersion program and 19 children from a regular second-grade…

The enhanced metalinguistic abilities demonstrated by additive-bilingual children, including superior control of cognitive processing, may promote the development of symbolic reasoning. Children educated in additive-bilingual (immersion) settings may maintain normal native-language development, while acquiring a second language. This study…

This study analyzed a public school prekindergarten Montessori bilingual program, investigating second grade reading achievement scores on Spanish and English norm-referenced tests and comparing students who had participated in the Montessori program with those who had participated in a prekindergarten traditional bilingual program. Participants…

A study consisting of two parts is reported. The first investigated the extent to which effective-teacher characteristics discussed in the literature were considered by parents and administrators to be salient in bilingual education. The second examined the extent to which students exhibited behavior suggesting they had received effective…

To determine the effect of books in Spanish and free reading time on reading abilities and attitudes of Hispanic students, 114 Hispanic children enrolled in grades 2 (Level I), 3 and 4 (Level II) in Tempe, Arizona, were placed in either experimental groups or control groups. Teachers in the experimental classes (E) were provided with books in…

This study followed longitudinal achievement data from Hispanic students with limited proficiency in English who participated in a pilot instructional program. The program involved bilingual curriculum content (BCC) in the home language and was initiated in the winter of 1983-84 and continued through the 1986-87 school year. Six elementary schools…
