Los componentes en la adquisición de la lengua en la escuela primaria mexicana: un caso de validación de constructos

Résumé 0

"A preliminary study was carried out to test a structural model consistingof four language components: reflection on the language,time for writing, speaking and listening, and reading and sharing.Seventy-one girls and sixty-seven boys in the fourth grade of Mexican public elementary schools were evaluated. The initialanalysis obtained an unsatisfactory model that confirmed onlytwenty of the thirty-six series of tasks first evaluated; in addition,the covariance between these four components was very high andsignificant. Since the data indicated that the childrenís productionwas not based on these four components or factors, an exploratoryfactorial analysis was completed to observe the grouping of variablesby factorial affinity. The four new resulting factors of theexploratory factorial analysis showed good internal consistency andwere later submitted to a confirming factorial analysis through aprogram of structural equations. A robust model with twenty-sevenseries of tasks was obtained, with divergent validity of the languagecomponents construct."
