El proyecto USAID Leer es una intervención de lectura y escritura en escuelas públicas de la República Dominicana en respuesta a sus bajos niveles de comprensión lectora. el objetivo del estudio fue determinar la eficacia del proyecto USAID Leer a través de dos estudios transversales (al iniciar el proyecto y en la mitad). Se realizó un estudio experimental con aleatorización de grupos (experimental vs. control) y una estimación del contrafactual basada en la evaluación de línea base. Participaron 2,399 alumnos de segundo grado para línea base, y 2,359 alumnos de cuarto grado para línea media. Se evaluaron comprensión lectora, habilidades precursoras a la misma (comprensión oral, conciencia fonológica, conocimiento de letras, lectura de palabras por minuto, lectura de pseudopalabras por minuto y fluidez), y habilidades cognitivas generales (memoria de trabajo de palabras y memoria de trabajo de pseudopalabras). Dentro de los resultados se destaca que no hubo diferencias entre los grupos durante la línea base. En la línea media, el grupo experimental obtuvo mejores puntuaciones que el grupo control en comprensión oral, conciencia fonológica, conocimiento de letras, lectura de palabras y pseudopalabras por minuto y memoria de trabajo de pseudopalabras. No hubo diferencias entre los grupos en fluidez ni en comprensión lectora. Se concluyó que la intervención fue efectiva, pero aún no ha alcanzado el umbral necesario para que sus efectos se reflejen más allá de las habilidades precursoras de la comprensión lectora. Los resultados se interpretan desde la teoría de la automatización lectora y la necesidad de mayor práctica lectora de los alumnos en proceso de alfabetización.

The Simple View of Reading (SVR) proposes that reading comprehension depends on two general processes –language comprehension and word recognition– and that the contribution of these known processes to reading comprehension varies in time. Specifically, the contribution of word recognition decreases, and the contribution of language comprehension increases with student progress. The purpose of this study was to test the SVR in a large sample of 4,750 Dominican public-school students from second (n = 2,399) and fourth grade (2,351) and determine the contribution of phonological awareness within the SVR. The study found that word recognition and language comprehension explained 80% of the variance in reading comprehension regardless of grade. A quantile regression showed that, as reading comprehension progresses, language comprehension’s predictive power increases, and word recognition’s predictive power decreases. A structural equation model conducted on each grade separately showed that the contribution of word recognition toward reading comprehension remained stable between second and fourth grade. This means that, although the dynamism of the SVR components follows the same pattern reported in the literature, the students evaluated here might reach reading automaticity later than expected. Therefore, more attentional resources need to be allocated toward decoding. The study found that the contribution of phonological awareness toward word recognition increases from second to fourth grade, confirming that students are taking longer than expected to obtain reading automaticity and still going through an overt effortful decoding stage rather than a covert phonological recoding stage, making reading more effortful.

The purpose of this study was to explore if there were differences between a group of Dominican sixth grade students that received project USAID-Read’s literacy intervention for two years and six months (n = 10,736) vs. the scores of students from a control group (n =11,135). Methods: This is a secondary data analysis from the sixth-grade national diagnostic evaluation from the Dominican Ministry of Education conducted in 2018 that assessed sixth-grade students' performance in language, math, science, and social studies. Results: The study found that students from project USAID-Read outperformed students from the control group in language and math. Students with the highest categorical scores in language and math were 13% and 56% more likely to belong to project USAID-Read, respectively. Discussion: This study shows the positive effects of a science-based reading intervention that consisted of teacher training, teacher mentoring, and providing students with systematic reading practice with reading materials created for this purpose.
