News Context: You will note this abstract says nothing about students' ability to use real words appropriately in academic writing. 
Paper Context: Only a very small percentage of words written in these exam papers could be counted as textisms and 43 of these occurred in a single student's paper. Overall, the proportion of textisms of all words in the written exams by all participants was a tiny 0.02% and, with the outlying student's results excluded, was reduced to only 0.01% (an average of approximately one textism in every 7200 words). Various other types of textism types that have been observed in previous research on actual text-messages (e.g., were not seen in the exam papers viewed in this study.
