This article analyzes 41 studies that evaluated K–12 parent involvement programs in order to assess claims that such programs are an effective means of improving student learning. It examines the characteristics of the parent involvement programs, as well as the research design, data, and analytical techniques used in program evaluation. Our examination of evaluations found little empirical support for the widespread claim that parent involvement programs are an effective means of improving student achievement or changing parent, teacher, and student behavior. We do not conclude that programs are ineffective. Rather, serious design, methodological, and analytical flaws inherent in studies evaluating the effectiveness of parent involvement programs must be addressed before definite conclusions about program effectiveness can be reached. The findings of this study are particularly significant given the substantial federal support for parent involvement.

This article discusses two investigations which explored the bilingual language development outcomes of comparable groups of low-income, Spanish-speaking, Mexican American children who either did or did not attended a bilingual (Spanish/English) preschool. Study 1 is a replication of a study by Rodríguez, Díaz, Duran, and Espinosa, involving a new sample of 26 children who attended bilingual preschool for one year and 20 control children who remained at home. Study 2 represents a 1-year, longitudinal follow-up of Rodríguez et al.'s, sample of children during and after the children spent another year at home or in the preschool. In both investigations, standardized, objective measures of three components of children's language proficiency (productive language, receptive language, and language complexity) in English and Spanish were obtained at the beginning and end of the academic year. Contrary to fears that have been expressed by some that early exposure to English would lead to children's native language loss, the results of both studies offered no evidence of Spanish proficiency loss for children attending bilingual preschool. Children who attended bilingual preschool, compared to those who remained at home, showed significant and parallel gains in Spanish language development as well as significant and greater increases in English language proficiency over time. Results are discussed in terms of the need for more systematic research to be conducted in this area to inform policy and practice in the early education and development of language-minority children.

This paper describes how a university outreach program promotes academic achievement and identity development among culturally diverse tenth-grade students. The primary goal of the outreach program is to advance students' engagement and competency in mathematics and science learning. A secondary goal of the program is to promote the development of students' academic and cultural identities. This paper describes how a university outreach program meets both goals of advancing participants' engagement and competence in mathematics and science while promoting the development of their academic identity and cultural awareness through the implementation of culturally responsive teaching practices. Qualitative data collected through student interviews will be examined to illuminate the program's effectiveness in promoting identity development and achievement in math and science. In addition, outcome data from the program's first four years (1998-2001) are presented to demonstrate its effectiveness at enhancing participants' academic competencies.
