“…Specifically, previous meta-analyses, in which experimental and quasi-experimental interventions were analyzed, showed that writing instruction through ICTs has a larger effect size than those conducted without them on students' textual quality, with significant improvements in their performance, motivation, organization, productivity, mechanics (i.e., readability, clarity, and flow), and content of their texts [17][18][19]. Regarding the findings found in previous empirical reviews, most have analyzed the effects of ICTs on different writing variables, showing that they improve both high-and low-cognitive-level writing processes, motivation, and performance [13,[20][21][22][23][24]. Moreover, in the case of high-level processes, it stands out that the most considered processes are planning and revision; and among the low-level processes, spelling, grammar, and phonological awareness stand out.…”
