ABSTRACT
El objetivo del trabajo fue determinar la validez y confiabilidad de la prueba tamiz del lenguaje en preescolares de 2 a 3 años del municipio de Juan De Acosta del Departamento del Atlántico. Fue un estudio descriptivo, cuantitativo, realizado a treinta preescolares del plan de atención "Educación y Desarrollo Integral para cada Colombiano". Se evaluó la validez del instrumento por parte de los jueces expertos, en relación a cada uno de los aspectos del lenguaje que contiene la prueba. La confiabilidad del instrumento, fue hallada mediante el estadístico ALPHA DE CRONBACH, aplicado al total de la muestra. Se encontró que el 66,7% están de acuerdo con que el aspecto pragmático es válido y el 33.3% que este aspecto es pertinente, claro y completo. Referente a los aspectos semántico y morfosintáctico en un 8.43, 8.46 y8.75 respectivamente. El aspecto fonético-fonológico de la prueba obtuvo una confiabilidad de 4.49, lo que determina que dicho aspecto presentó una baja consistencia interna. Se concluyó que los índices obtenidos en la validación del instrumento generados por el coeficiente de correlación, demuestran que la prueba tamiz de lenguaje diseñada para preescolares de 2 a 3 años es válida, pertinente, clara y completa.
