(a) Disorders of reading accuracy and oral language skills . Although there is more to reading comprehension than vocabulary, there is good More generally, both Developing Reading Comprehension by Clarke, .. Children's comprehension problems in oral and written language: A. Taking skills and oral language development have a strong impact Help your child recognize the relationship between speech and writing by.
For spoken language, it is common to distinguish between four domains: When we consider written language, we need to distinguish between reading and spelling. Within the domain of reading, it is important to make a further distinction between decoding usually assessed by the accuracy or fluency of reading aloud and comprehension the adequacy of understanding text, usually assessed by questions about the meaning of a passage.
Mattingly [ 1p. He was correct in the sense that a child's ability to learn to recode print which was the topic of his chapter is critically dependent on their phonological, or speech sound, skills. In short, reading for meaning depends on all four domains of oral language. The intimate relationship between spoken and written language skills has been long accepted in studies of development, but perhaps less so in studies of acquired disorders of these skills. However, the primary systems hypothesis [ 34 ] sees adult cases of reading disorders, just like developmental cases, as reflecting impairments to underlying primary brain systems systems concerned with different aspects of oral language as well as visual processing mechanisms.

This view suggests that models of acquired and developmental disorders of reading already show a good degree of alignment. Models of reading development and reading disorders Understanding a disorder of development depends on having a model of normal development for the skill in question [ 5 ].
More broadly, any complete model of cognitive performance in adulthood needs to be compatible with evidence about how the process in question developed. Studies of development can, in turn, inform and constrain theories of adult psychological functioning. To quote Baldwin [ 6p. The argument that is at the heart of this review, that language problems are the predominant causes of problems in learning to read, rests upon two different models of how language processes operate to determine the course of normal reading development: Currently, there are two influential classes of model of adult word reading: Dual-route models conceptualize adult word recognition as depending upon independent lexical and sublexical routes from the written form of a word to its pronunciation.
By contrast, connectionist theories of word reading are explicitly developmental and see word reading as being dependent upon the integrity of phonological and semantic representations that exist in the language processing system before reading develops. According to the triangle model, learning to read essentially consists of creating mappings or associations between visual representations of the letter strings that constitute words orthographic representations and the phonological and semantic representations of spoken language that correspond to those words.
The interface between spoken and written language: developmental disorders
The use of the semantic pathway may be particularly important for the reading of exception words that the phonological pathway does not handle efficiently.
As noted earlier, it is important to distinguish between the ability to read words accurately and fluently and the ability to comprehend text. Accurate and fluent word reading are essential for good reading comprehension. It follows from this model that problems with reading comprehension can arise from two different sources problems with decoding or problems with oral language comprehension.

Text reading and writing Recent studies have shown that the correlations between passage comprehension and text composition range from moderate to high for both children and adults Berninger et al. Readers apply a series of inferences and construct propositions based on the information provided by the text Foorman et al. Additionally, they form mental models of the text that represent the situation described in the text. However, the pattern of reasoning is different for each process: The important conclusion from the reading-writing research is that although reading and writing are not inverse processes, they rely on similar cognitive mechanisms that allow for simultaneous growth as well as transfer of knowledge.
A recent study by Abbott, Berninger and Fayol modeled the longitudinal development of reading and writing across levels of language. Their study placed emphasis on integrating levels of language by specifying several bidirectional models. Their study included data of children who were tested longitudinally from grades one through seven. They included handwriting a sub-word skill to clarify conflicting results of earlier longitudinal studies that show both bidirectional and unidirectional relations between word reading and spelling.
The results showed a significant bidirectional relation between word reading and spelling across grade 2 through 7. For grade 1, however, only the spelling to reading pathway was significant. Their second bivariate model included pathways between word word reading and spelling as well as text level measures reading comprehension and written composition. Similarly, this theoretical framework was applied to writing, whereby writing was conceptualized as a product of word level writing spelling and text level writing composition.
Similar to the first model, the results for this model showed significant bidirectional relations between word spelling and reading for grade 2 through 7. For grade 1, however, only the path from word reading to spelling was significant in this model. Similarly, at the text level, their results showed that the magnitude of the bivariate parameters were small. The stability parameters were larger in magnitude and ranged from.
Overall, their results indicate relations between reading and writing at the word and text levels are less clear in grade 1 than in subsequent grades, possibly because other factors such as verbal ability or exposure to print contribute to the development of reading and writing at that grade level. The results showed that differences in magnitude between the stability parameters and bivariate parameters show a weak relation between reading and writing processes, and strong a reading-reading and writing-writing relation.
However, their study used observed indicators as measures of reading and writing ability. The use of observed indicators assumes that the constructs were measured without error, and the stability parameters could largely be inflated due to common method variance. Latent Change Score Modeling A new model for analyzing longitudinal data called latent change models provide an important new tool for analyzing relations between developing reading and writing McArdle, LCS models combine the strengths of cross-lagged structural models and latent growth curve models, the two kinds of models that are most commonly applied to longitudinal developmental data.
Similar to cross-lagged structural models and unlike latent growth curve models, LCS models divide development into segments of time. This allows the use of time-sequence logic e.
This may include but is not limited to analyzing the word's morphology roots and affixes and syntax part of speechsearching for context clues, or looking up the word in the dictionary . Back to Top What challenges do adolescent readers face with vocabulary?
Because word identification is one of the foundational processes of reading, middle and high school students with poor or impaired word identification skills face serious challenges in their academic work. Some struggling adolescent readers have difficulty decoding and recognizing multi-syllabic words.
For example, words such as "accomplishment" leave many struggling readers unsure about pronunciation or meaning. This is often the case not just because their vocabulary is limited, but also because they are unaware of or not proficient in word-learning strategies based on understanding the meanings and functions of affixes e.
In content areas in which text is more technical and abstract, insufficient vocabulary knowledge can become especially problematic for struggling readers. A major goal of vocabulary instruction is to facilitate students' ability to comprehend text . In addition, the meanings of many words vary from context to context and from subject to subject, making academic vocabulary especially difficult to acquire. For example, the word meter has distinct definitions in different content areas.
In literature, a meter is a poetic rhythm and in math, it is a unit of measurement. In science, a meter is a device for measuring flow.
Students may experience difficulty if they do not understand that words have multiple meanings . Back to Top How can instruction help adolescent students with vocabulary? Research findings suggest that there is not a single best way to teach vocabulary ; rather, using a variety of techniques that include repeated exposures to unknown word meanings produces the best results.
Traditionally, independent word-learning strategies, such as the use of dictionaries and context clues, have been common strategies for teaching new vocabulary.
Dictionary usage involves multiple skills, such as using guidewords, decoding, and discerning correct definitions . Using context clues involves integrating different types of information from text to figure out unknown vocabulary.
These strategies are helpful after multiple encounters with a word but should be used in combination with other instructional practices . The following vocabulary development strategies have been found to be effective in improving adolescent literacy levels. Pre-teach difficult vocabulary Pre-teaching vocabulary facilitates the reading of new text by giving students the meanings of the words before they encounter them. This practice reduces the number of unfamiliar words encountered and facilitates greater vocabulary acquisition and comprehension .
Leaving students on their own to grasp the content material as well as to decode possibly unfamiliar vocabulary is setting them up for failure.
Teachers can introduce both the more unfamiliar specialized academic words that will be used in the lesson as well as non-specialized academic words used when talking about the content. When considering which non-specialized academic words to emphasize, teachers should consider the structure or structures used in the text.
Text structures organize ideas and information according to certain patterns. For example, cause and effect patterns show the relationship between results and the events, people, or ideas that cause the results to occur.
Teachers can use the following guidelines when selecting vocabulary to pre-teach: Importance of the word for understanding the text; Students' prior knowledge of the word and the concept to which it relates; The existence of multiple meanings of the word e. Once vocabulary words have been selected, teachers should consider how to make repeated exposures to the word or concept productive and enjoyable. For example, when introducing a particular word, pronounce it slowly to draw attention to each syllable, provide the word's meaning, examine word parts e.
After introducing all words, have students work in pairs or small teams to create groups of related words and to label these groups. Students can then take turns explaining to the class their reasons for grouping words in a particular manner.
