Environmental content is becoming increasingly important in schools, but teachers may have difficulty grasping accurate knowledge. This study investigated how student teachers construct a conceptual understanding of biodiversity loss in an online environment. Sixty-five first-semester primary student teachers at a Finnish university were given the…

Purpose: Complex features of science texts present idiosyncratic challenges for middle grade readers, especially in a post-Common Core educational world where students' learning is dependent on understanding informational text. The primary aim of this study was to explore how middle school readers process science texts and whether such…

According to the RAND model framework, reading comprehension test performance is influenced by readers' reading skills or reader characteristics, test properties, and their interactions. However, little empirical research has systematically compared the impacts of reader characteristics, test properties, and reader-test interactions across…

The 2018 NAEP Oral Reading Fluency (ORF) study is conducted by NCES to examine fourth-grade students' ability to read passages out loud with sufficient speed, accuracy, and expression, as well as foundational skills to gauge underlying sources of poor fluency. Oral reading fluency and foundational skills are important components of reading that…

This paper considers whether the sources of linguistic complexity presented within texts targeted at 1st-grade readers have increased, decreased, or held steady over the 52-year period from 1962 to 2013. A collection of more than 450 texts is examined. All texts were selected from Grade 1 textbooks published by Scott Foresman during the targeted…

In this conceptual essay, we offer rationales and evidence for critical components of a working model of text complexity for the early grades. In the first three sections of the article, we examine word-level, syntax-level, and discourse-level features of text, posing questions for future research. In the fourth section, we address elements of…
