Data of a single-case experimental study on the effects of adaptations of a phonics-based reading intervention program on the reading and spelling skills of students with intellectual disability who require augmentative and alternative communication

The second column of the file indicates the measured outcome (the dependent variable). The two dependent variables in this study were (a) the number of words correctly read and (b) the number of words spelled phonetically correctly (i.e., spelled the way they sound).

During probes, the number of words that students were able to spell orthographically correctly (i.e., written correctly with a silent letter at the end) was also assessed because many French words end in a silent letter. The third colum ("Phase Name") indicates the phase name: baseline phase (before the introduction of the intervention), intervention phase and maintenance (measures administered at lest two weeks after the end of the intervention).
