“…In this study, we used three narrative texts selected from didactic books and three expository texts were elaborated (1) with appropriate syntactic complexities for each of the investigated school years (Flesch index I and frequency of occurrence of words II , number of words and sentences in the text, sentences per paragraph, type/token III , incidence of content words IV , incidence of pronouns, number of pronouns by phrase V , and number of connectives VI ). In addition, all narrative texts respond to the grammar of the stories containing settings and episodes divided in: initiating event, internal response, planning, execution, consequence, and reaction (25) . The expository texts were elaborated containing themes related to the educational content of school years ahead of those of the children evaluated, with the intention to restrict the influence of their prior knowledge on the reading comprehension.…”
