The core task of reading is to look at letters and identify their sounds and meaning. In English, the spelling system is "quasiregular," meaning it includes many reliable patterns (some so reliable they could be called "rules") but also many inconsistent ones (the sound of "EA" in "heat" vs.…

Dealing with the vast quantities of text that students generate in Massive Open Online Courses (MOOCs) and other large-scale online learning environments is a daunting challenge. Computational tools are needed to help instructional teams uncover themes and patterns as students write in forums, assignments, and surveys. This paper introduces to the…

Most of us recall with pain the unpleasant experiences associated with the teacher's announcement that we would once again initiate a unit of learning designed to both widen and deepen our knowledge of the words of our language. This was said to establish the foundation for all of our future academic pursuits. A strong vocabulary was said to be a…

This paper provides a short overview of current issues in research on continuous reading in non-Roman orthographies. At the same time it also serves as an introduction to the present Reading and Writing Special Issue on this topic. The main questions examined in the contributions to this volume are closely related to issues that have been central…

Instructional design is an integral part of a balanced approach to teaching vocabulary instruction. This article presents several instructional procedures using research-based vocabulary strategies and explains how to design and adapt those strategies in order to reach desired learning outcomes. Emphasis is placed on research-based principles that…

Students find it hard to interpret mathematical problem texts. Mathematics is a unique language with its own symbols (grapho-phonics), vocabulary (lexicon), grammar (syntax), semantics and literature. As in any other language, to make meaning of the text, the student must learn: (1) signs and symbols (for example: [division], x, [not equal to]);…

This article makes use of Perfetti's Lexical Quality Hypothesis as a perspective for thinking about vocabulary instruction in terms of semantics (meaning), phonology (pronunciation), orthography (spelling), morphology (meaningful word parts), and syntax (how words function in sentences). Examples are presented of how these aspects of vocabulary…

The activities described in this article, Prediction Path and Quotation Cafe, are adapted from the IRA book "Building Reading Comprehension Habits in Grades 6-12." They highlight the reading comprehension habit of making inferences and predictions, which can be used across content areas and grade levels. In creating this toolkit of activities, the…

Computer analyses of text characteristics are often used by reading teachers, researchers, and policy makers when selecting texts for students. The authors of this article identify components of language, discourse, and cognition that underlie traditional automated metrics of text difficulty and their new Coh-Metrix system. Coh-Metrix analyzes…

Research has shown that the use of pre-reading activities, such as graphic or advance organizers can positively affect student acquisition of vocabulary and meaning when reading new concepts presented in text. One particularly effective strategy, semantic mapping, can significantly impact students who previously had a lack of prior knowledge on…

Numerous definitions of literacy have been advanced by policy-makers, politicians, academics, teachers and others over the years. It is not always easy, however, to know how one definition might relate to another or differ from it. This paper offers a framework, based on the work of the educational philosopher Israel Scheffler, for identifying and…

We summarize some of the most important findings from research evaluating the hypothesized causes of specific reading disability ("dyslexia") over the past four decades. After outlining components of reading ability, we discuss manifest causes of reading difficulties, in terms of deficiencies in component reading skills that might lead to such…

This article presents a theory of visual word recognition that assumes that, in the tasks of word identification, lexical decision, and semantic categorization, human readers behave as optimal Bayesian decision makers. This leads to the development of a computational model of word recognition, the Bayesian reader. The Bayesian reader successfully…

College students learning about language and using this knowledge to learn how to teach reading and writing should participate in strategies that simulate systems in the language and strategies that they in turn will use in their own classrooms. Cognitive and constructivist strategies are interactive and thus more powerful than the traditional…
