Abstract
This study examined the role of variability and change in children’s strategy performance within the context of spelling. The spelling ability of 34 eight‐ to nine‐year‐olds was examined using an experimental spelling task comprising 45 items, which varied with regard to rime unit frequency. The spelling task incorporated a series of consistent, unique, and exception word items. Children were tested on the same spelling task on three separate occasions over a period of three months. Performance was examined using immediately retrospective verbal self‐reports after the presentation of every word. The findings showed that children spelt words strategically and were adaptive in their strategy selection, showing a general change from using less efficient backup strategies to using more efficient direct retrieval methods over time. Finally, while those less skilled in spelling showed a greater reliance on less efficient backup strategies, the skilled spellers mainly retrieved the correct spellings from memory. However, accuracy only improved across time intervals for each skill group when spelling unique word items. Overall, the findings illustrate the benefits of using a detailed microgenetic approach to assess the progress children make in learning to spell.
