This study evaluated whether the sophistication of children’s invented spellings in kindergarten was predictive of subsequent reading and spelling in Grade 1, while also considering the influence of well-known precursors. Children in their first year of schooling were assessed on measures of oral vocabulary, alphabetic knowledge, phonological awareness, word reading, and invented spelling; approximately one year later they were assessed on multiple measures of reading and spelling. The researchers found a direct line from invented spelling leading to improved reading scores at the end of first grade. The study suggests that invented spelling integrates phonological and orthographic growth and is a unique predictor of growth in early reading skills, over and above children’s alphabet knowledge and phonological awareness.

Some scholars have argued that spelling should not be directly or formally taught as such instruction is not effective or efficient. The authors conducted a comprehensive meta-analysis of experimental and quasi-experimental studies to address these claims. Results provided strong and consistent support for teaching spelling, as it improved spelling performance when compared to no/unrelated instruction or informal/incidental approaches to improving spelling performance. Increasing the amount of formal spelling instruction also proved beneficial. Gains in spelling were maintained over time and generalized to spelling when writing. Improvements in phonological awareness and reading skills were also found. The positive outcomes associated with formal spelling instruction were generally consistent, regardless of students’ grade level or literacy skills.

Orthographic mapping (OM) involves the formation of letter-sound connections to bond the spellings, pronunciations, and meanings of specific words in memory. It explains how children learn to read words by sight, to spell words from memory, and to acquire vocabulary words from print. This development is portrayed as a sequence of overlapping phases, each characterized by the predominant type of connection linking spellings of words to their pronunciations in memory. During development, the connections improve in quality and word-learning value, from visual nonalphabetic, to partial alphabetic, to full grapho-phonemic, to consolidated grapho-syllabic and grapho-morphemic. OM is enabled by phonemic awareness and grapheme-phoneme knowledge. Recent findings indicate that OM to support sight word reading is facilitated when beginners are taught about articulatory features of phonemes and when grapheme-phoneme relations are taught with letter-embedded picture mnemonics. Vocabulary learning is facilitated when spellings accompany pronunciations and meanings of new words to activate OM. Teaching students the strategy of pronouncing novel words aloud as they read text silently activates OM and helps them build their vocabularies. Because spelling-sound connections are retained in memory, they impact the processing of phonological constituents and phonological memory for words.

Primary grade teachers randomly selected from across the United Sates completed a survey (N = 168) that examined their instructional practices in spelling and the types of adaptations they made for struggling spellers. Almost every single teacher surveyed reported teaching spelling, and the vast majority of respondents implemented a complex and multifaceted instructional program that applied a variety of research-supported procedures. Although some teachers were sensitive to the instructional needs of weaker spellers and reported making many different adaptations for these students, a sizable minority of teachers (42%) indicated they made few or no adaptations. In addition, the teachers indicated that 27% of their students experienced difficulty with spelling, calling into question the effectiveness of their instruction with these children.

Over the years, researchers' thinking about "spelling" has evolved. Once seen simply as a tool for writing, it's now acknowledged that spelling offers perhaps the best window on what an individual knows about words. Learn how spelling has been reconceptualized, and the implications for spelling instruction.
