Children's word structure knowledge: Implications for decoding and spelling instruction

Research has shown that not all children internalize the structure of English orthography as they learn to decode and spell. In fact, many children have difficulty mastering these two skills. In this paper, the relevance of word structure knowledge to decoding and spelling instruction and performance is discussed. It was anticipated that explicit, discussion oriented, and direct decoding instruction based on word origin and structure would result in improved reading and spelling performance. During the instruction, students compared and contrasted letter-sound correspondences, syllable patterns, and morpheme patterns in English words of Anglo-Saxon, Romance, and Greek origin. Upper elementary grade students receiving the decoding instruction made significant gains in word structure knowledge and in decoding and spelling achievement.     

Word decoding development in incremental phonics instruction in a transparent orthography

The present longitudinal study aimed to investigate the development of word decoding skills during incremental phonics instruction in Dutch as a transparent orthography. A representative sample of 973 Dutch children in the first grade (M _age  = 6;1, SD = 0;5) was exposed to incremental subsets of Dutch grapheme–phoneme correspondences during 6 consecutive blocks of 3 weeks of phonics instruction. Children’s accuracy and efficiency of curriculum embedded word decoding were assessed after each incremental block, followed by a standardized word decoding measurement. Precursor measures of rapid naming, short-term memory, vocabulary, phonological awareness, and letter knowledge were assessed by the end of kindergarten and subsequently related to the word decoding efficiency in the first grade. The results showed that from the very beginning, children attained ceiling levels of decoding accuracy, whereas their efficiency scores increased despite the incremental character of the consecutive decoding assessments embedded in the curriculum. Structural equation modelling demonstrated high stability of the individual differences assessed by word decoding efficiency during phonics instruction during the first 5 months of the first grade. Curriculum embedded word decoding was highly related to standardized word decoding after phonics instruction was completed. Finally, early literacy and lexical retrieval, and to a lesser extent verbal and visual short term memory, predicted the first fundamental processes of mastering word decoding skills.     

A meta-analysis on the effectiveness of phonics instruction for teaching decoding skills to students with intellectual disability

This meta-analysis examines the effects of phonics instruction on the decoding skills of students with intellectual disability using a random-effects model. Eight single-case experimental studies and six experimental or quasi-experimental group studies met the inclusion criteria, encompassing a total of 297 participants with intellectual disability. The overall effect of phonics instruction on the decoding skills of persons with intellectual disability was large: g = 1.42 (95% CI: 0.75, 2.10). Single-case studies yielded a larger average effect size (g = 1.94, 95% CI: 1.10, 2.78) than group studies (g = 0.41, 95% CI: 0.13, 0.69). Researcher-designed tests also yielded larger effect sizes than standardized tests. The type of interventionist was not a significant moderator. In the majority of the studies, phonics instruction was carried out using a systematic and direct instruction approach and a one-to-one format. Implications for practice and research are presented, and areas that require further investigation are identified.     

The impact of multisensory instruction on learning letter names and sounds,word reading,and spelling

The purpose of this study was to investigate whether the use of simultaneous multisensory structured language instruction promoted better letter name and sound production, word reading, and word spelling for second grade children with typical development (N = 6) or with dyslexia (N = 5) than structured language instruction alone. The use of non-English graphemes (letters) to represent two pretend languages was used to control for children’s lexical knowledge. A multiple baseline, multiple probe across subjects single-case design, with an embedded alternating treatments design, was used to compare the efficacy of multisensory and structured language interventions. Both interventions provided explicit systematic phonics instruction; however, the multisensory intervention also utilized simultaneous engagement of at least two sensory modalities (visual, auditory, and kinesthetic/tactile). Participant’s graphed data was visually analyzed, and individual Tau-U and weighted Tau-U effect sizes were calculated for the outcome variables of letter name production, letter sound production, word reading, and word spelling. The multisensory intervention did not provide an advantage over the structured intervention for participants with typical development or dyslexia. However, both interventions had an overall treatment effect for participants with typical development and dyslexia, although intervention effects varied by outcome variable.     

Effects of psycholinguistic instruction on spelling performance

Two studies were conducted in which phonology‐based instructional strategies designed for improving spelling skills of elementary school children were compared against instruction strategies that relied only on visual exposure of words. The first study involved a total of 93 children. Of these, 46 were instructed by drawing their attention to the psycholinguistic nature of their spelling errors. The remaining 47 children in the comparison group were shown the correct version of all the words. In study II 15 children were placed in a treatment group and were taught phoneme awareness, and 15 children were placed in a comparison group and were exposed to printed words only. In both studies, posttests showed that children taught through psycholinguistic and phoneme awareness methods significantly outperformed the visual training groups. Further, these gains were retained after a period of 2 weeks. © 2001 John Wiley & Sons, Inc.     

Implicit and explicit instruction of spelling rules

The study aimed to compare the differential effectiveness of explicit and implicit instruction of two Dutch spelling rules. Students with and without spelling disabilities were instructed a spelling rule either implicitly or explicitly in two experiments. Effects were tested in a pretest-intervention-posttest control group design. Experiment 1 suggested that explicit instruction of a morphological spelling rule led to instance-based knowledge in students with spelling disabilities and to rule-based knowledge in students without. Implicit instruction led to instance-based knowledge in students with spelling disabilities, and in the group without spelling disabilities no learning at all occurred. Experiment 2 revealed that explicit and implicit instruction of an orthographical spelling rule were equally effective in both groups and that the spelling knowledge they had acquired was instance-based. Findings suggest that explicit instruction is more effective than implicit instruction for the teaching of spelling rules when generalization is aimed at.     

Getting the right balance: Effective classroom spelling instruction

Abstract

Historically, spelling approaches have been broadly classified as ‘child‐centred’ or ‘instruction‐centred’ but, in recent times teachers have tended to combine elements of these theoretically different perspectives to design new approaches. The findings of research reporting teacher dissatisfaction with such combined approaches is contrasted with the experiences of staff (teachers of Years 2–5) from one Western Australian primary school. The setting was of interest because compared to populations of children in surrounding areas students at Grove Primary School demonstrated consistently higher spelling results in statewide tests. Rather than subscribing to a particular approach, the teachers reported employing a combined approach that included incidental spelling instruction in the context of literature in conjunction with teacher directed and student initiated word study. At the same time, all teachers reported a commitment to spelling practices aligned with an instruction‐centred approach including separate spelling lessons each morning of at least 20 minutes in duration and weekly or fortnightly pretest‐learn‐test cycles of word lists.     

Artificial intelligence tools for grammar and spelling instruction

In The Netherlands, grammar teaching is an especially important subject in the curriculum of children aged 10–15 for several reasons. However, in spite of all attention and time invested, the results are poor. This article describes the problems and our attempt to overcome them by developing an intelligent computational instructional environment consisting of: a linsuistic expert system, containing a module representing grammar and spelling rules and a number of modules to manipulate these rules; a didactic module; and a student interface with special facilities for grammar and spelling. Three prototypes of the functionality are discussed: BOUWSTEEN and COGO, which are programs for constructing and analyzing Dutch sentences; and TDTDT, a program for the conjugation of Dutch verbs.     

Multilayered word structure model for assessing spelling of Finnish children in shallow orthography

This study explores Finnish children's word‐level spelling by applying a linguistically based multilayered word structure model for assessing spelling performance. The model contributes to the analytical qualitative assessment approach in order to identify children's spelling performance for enhancing writing skills. The children (N = 105) participated in two dictation assessments at the end of their first and second grades. The results indicate that long consonants and consonant sequences are the most problematic structures in both the first and second grades. The less‐advanced spellers were significantly weaker than others also in coding the overall syllable number, heavy unstressed syllables and long vowels in the first grade. In the second grade, they still had more difficulties in spelling heavy unstressed syllables and long quantities of vowels and consonants. The multilayered word structure model seems to give more information about the quality of spelling than error‐based holistic analyses. The model is applicable for other shallow orthographies as well.     

The effect of phonics instruction on the reading comprehension of beginning readers

This study investigated whether two groups of6-year-old beginning readers taught to read by aphonics and by a ``book experience' non-phonicsapproach would differ in reading comprehension as wellas the processes of word recognition. The two groupswere matched for word recognition but despite this, thephonics taught children had higher readingcomprehension. Phonics taught children produced morecontextually appropriate errors, and in both singleword and text reading made more spoken attempts atreading unknown words. The non-phonics taught childrenhad much faster reading reaction times to familiarwords but they scored less in phoneme segmentation andnonword reading tasks. Compared with the nonphonicsgroup, the phonics group spent more time in attemptsat identifying unknown words and this included usingcontextual information, which apparently resulted inmore rehearsal of the meaning of the story text andhence better reading comprehension performance.     

Beyond decoding: Pictures of expository prose

Just as success in decoding complex spelling patterns requires strategy and structure, so does the “decoding” of complex expository writing. We discuss the specific sources of difficulty in technical writing and distinguish between content structure and text structure. Next come presentations of the basic building blocks for expository writing and techniques of text design. Patterns from American science and social studies texts are described and contrasted with Japanese materials. We finish with suggestions for promoting the comprehension of expository materials. This article is taken from an address delivered on November 5, 1987 by the first author to the 38th Annual Conference of the Orton Dyslexia Society in San Francisco. The use of first person captures certain facets of the presentation, but the paper is mostly a “we” piece.

Diagnosing word decoding problems: A process-analytic approach

In this article we attempt to demonstrate the theoretical and practical limitations of traditional subgroup classifications of acquired and developmental dyslexia. As an alternative, we suggest a process-analytical approach. A variant of a dual-route model for word processing is presented. The model guided the design of a computerized test battery for assessing strategies in word decoding and processes underlying each strategy. The usefulness of the approach was demonstrated on two cases, which according to traditional criteria, were classified as auditory dyslexics. Although both cases displayed marked deficiencies in the phonological route for word decoding, they differed in terms of underlying processes. In one case the primary problem could be located to phonological synthesis, whereas the other case had poor access of letters (phonological recoding). Such individual processing characteristics are not normally revealed by the traditional subgrouping approach.     

Phonological awareness and decoding in deaf/hard-of-hearing students who use visual phonics

Visual phonics, a system of 45 hand and symbol cues that represent the phonemes of spoken English, has been used as a tool in literacy instruction with deaf/hard-of-hearing (DHH) students for over 20 years. Despite years of anecdotal support, there is relatively little published evidence of its impact on reading achievement. This study was designed to examine the relationship between performance on a phonological awareness task, performance on a decoding task, reading ability, and length of time in literacy instruction with visual phonics for 10 DHH kindergarten through Grade 3 students receiving academic instruction with sign-supported English and American Sign Language. Findings indicate that these students were able to use phonological information to make rhyme judgments and to decode; however, no relationship between performance on reading ability and length of time in literacy instruction with visual phonics was found.     

Facilitating invented spelling through language analysis instruction: An integrated model

Invented spelling ability reflects young children's developing awareness of the internal structure of words-at syllabic, phonemic, and morphemic levels, as well as their lettersound knowledge. Controlled intervention studies have demonstrated that these language analysis skills can be taught in kindergarten, with a significant effect on early spelling. This paper examines the effects of an instructional approach that emphasized integration of language analysis teaching into the whole-language kindergarten curriculum. Children who received this type of instruction were, on average, representing all of the phonemes in written words at the end of kindergarten, and their performance continued to improve into first grade.     

The relationship between rapid naming and word spelling in English

A study of the concurrent relationships between naming speed, phonological awareness and spelling ability in 146 children in Years 3 and 4 of state‐funded schools in South‐East England (equivalent to US Grades 2 and 3) is reported. Seventy‐two children identified as having normal phonological awareness but reduced rapid automatised naming (RAN) performance (1 standard deviation below the mean) participated in the study. A group of 74 children was further identified. These children were matched on phonological awareness, verbal and nonverbal IQ and visual acuity, but all members of this group showed normal RAN performance. RAN made a significant unique contribution to spelling performance. Further analyses showed that participants with low naming performance were significantly poorer spellers overall and had a specific difficulty in spelling irregular words. The findings support the view that RAN may be indexing processes that are implicated in the establishment of fully specified orthographic representations.     

Visual and orthographic information in learning to read and the influence of phonics instruction

In the Jackson and Coltheart theory of acquisition of word reading it is claimed that, near the beginning of the partial alphabetic phase of development, children have full use of abstract letter units (ALUs). This claim and less exclusive alternatives were examined. In Experiment 1, normal progress children with on average 9 months of school reading instruction, either with or without explicit phonics, read with moderate accuracy (orthographically) familiar words in upper-case letters (e.g., AND) that are visually dissimilar from their lower-case forms. Lower-case forms were read with greater accuracy but only for familiar words, there being no letter-case effect for less familiar words. Children with explicit phonics showed less impairment in reading accuracy when words were presented in upper-case form than children without such phonics. Children with on average 22 months of instruction, in Experiment 2, read relatively unfamiliar words that required some phonological mediation. Those without explicit phonics instruction read words with digraphs in unfamiliar upper case less accurately than in lower case, while those with explicit phonics showed no such letter-case difference. The results supported the view that children do not have full use of ALUs in early alphabetic reading, both children with and without explicit phonics to some extent using letter identities specific to lower case for representation of familiar words.
