Literacy Difficulties and Single-Case Experimental Design

It is widely agreed that methods for evaluating the persistence of literacy difficulties require further development and research. This paper considers the use of single-case experimental design and reports an intervention study that involves monitoring the learning of eight children. The research examines to what extent the children make progress on the 'probe tests' based on the teaching programmes and, if progress is made, how it is reflected in scores on the Phonological Assessment Battery, British Ability Scale tests of reading and spelling, and the Neale Analysis of Reading Ability. The advantages and pitfalls of single-case experimental design are discussed in the light of this research .
