A sharp increase in the proportion of informational text with the corresponding expansion of cognitive demands and conceptual structures is a widely held explanation for the decline inreading achievement at the fourth-grade level. In this study, differences in the proportion of informational text across the second, third, and fourth grades were examined in order to determine if this perennial explanation for the fourth-grade slump was supported. Available print materials in 15 classrooms (5 per grade) and time spent with texts in written language activities were coded and analyzed by text type following Duke’s (2000) data-collection procedures. The proportion of informational text in classrooms was slightly higher in grade 2; in classroom environmental print it was highest in grade 3, followed by grade 4 and then grade 2; in classroom written language activities it showed a marked increase from grades 2 to 3, with that increase sustained in grade 4. Total instructional time with informational text was an average of 1 minute in grade 2 and 16 minutes in grades 3 and 4. The most common instructional activities with informational text were reading to complete a worksheet and round-robin reading.

Investigates elementary school teachers' beliefs and classroom practices about reading. Describes how three of the teachers experimented with new language, beliefs, and/or practices, juxtaposing them with current beliefs and practices. Considers how, at the end of two years, two teachers had altered their beliefs and transformed their practices, primarily because of their inquiry approach.
