摘要：El objetivo de este estudio fue evaluar las habilidades lingüísticas con que ingresan a la educación básica primaria alumnos de estrato socioeconómico bajo. Participaron 262 alumnos de primer grado, inscritos en ocho grupos de escuelas públicas del Estado de México, con una media de 5.7 años de edad. Se aplicó individualmente a cada alumno el Instrumento para Evaluar Habilidades Precurrentes para la Lectura (EPLE), de Vega (1991), al inicio del ciclo escolar 2004-2005. El análisis estadístico con el programa SPSS arrojó como resultado un puntaje promedio de 77 (DS=14), que corresponde al 57% de la califi cación total del EPLE, lo que puede indicar que los alumnos ingresaron al primer grado de primaria con un nivel insatisfactorio de conductas lingüísticas. Se observan ligeras diferencias en las ejecuciones de los alumnos, a favor de quienes ingresaron con seis años de edad y con mayor número de años cursados en preescolar. Se discuten las implicaciones del bajo nivel lingüístico mostrado por los participantes y se proponen alternativas basadas en la investigación psicológica conductual.
其他摘要：The purpose of this study was to assess the linguistic skills of children from a low socioeconomic background who were beginning their elementary education. A total of 262 fi rst-grade students with an average age of 5.7 years old and who were enrolled in 8 groups of public schools from Mexico State, participated in this project. The instrument used was the Precurrent Skills for Reading Assessment (PSRA) by Vega (1991), and was administered individually to each student at the beginning of the 2004-2005 school year. The statistical analysis using SPSS showed a mean score of 77 (SD=14), which corresponds to 57% of the total PSRA score. These results may indicate that fi rst grade students have an unsatisfactory level of linguistic behaviour. Slight differences in the students performances were observed. A slightly better performance was shown by those fi rst grade students who were 6 years old at the beginning of the school year and who had previously received pre-school education. The implications of the poor linguistic level shown by the participants are discussed, and some alternatives based on the behavioural research, are proposed.
