Word Prediction


When using word recognition software as the user types each letter, the software predicts the intended word (offering a list of adjustable length). If the intended word is in the list, the user can type the number of the word or point and click with the mouse to insert the word in the sentence. If the intended word is not present, the student can keep typing and different options will appear (MacArthur, 1996). Most research on word recognition software is quasi-experimental in nature (e.g., Evmenova, Graff, Jerome, & Behrmann, 2010; Mezei & Heller, 2012; Silio & Barbetta, 2010), but has found similar results. Specifically, researchers have found that spelling errors decreased and that total number of words for written expression tasks increased when students use word recognition (Evmenova et al., 2010). MacArthur (1998) stated that there must be a match between the student’s needs and the chosen assistive technology, especially when it comes to using word recognition software because students often require extensive training and may find the software frustrating. 


Research Rating: The information cited in this description this information is quasi-experimental, and therefore is moderately reliable for decision-making purposes. 



  • Has been shown to decrease spelling errors and increase number of words in writing samples



  • Students may require extensive training and find the software frustrating


To Consider
