Differential Effects of a Tablet-Based Writing Intervention on Text Quality: An Intervention Study
Abstract
Differential Effects of a Tablet-Based Writing Intervention on Text Quality: An Intervention StudyStudents with weak writing skills struggle with text production and content learning, underscoring the need for early support (Becker-Mrotzek et al., 2014). Digital writing environments, such as those offering spell-checking and text-to-speech functions, may provide such support, particularly for weak writers (Graham & Harris, 2018). Yet despite their growing use in schools, little is known about which learners benefit most and how digital tools differentially affect the development of text quality.This study, conducted within the BMBF-funded EdToolS project, examines differential effects of a tablet-based writing intervention on text quality among 7th-grade students (N = 153) using a pre–post–follow-up design with a control group. Text quality was assessed using keyboard-written texts. The intervention comprised strategy instruction and training in the use of a word processor (spell-checking in EG1/EG2; text-to-speech in EG2), followed by a practice phase in which students wrote multiple texts (EG1/EG2: using tablet and tools, CG: handwritten). A language competence score derived via PCA was used to classify students into high- and low-performance groups.Linear regression models revealed that low performers in EG1 showed significantly greater short-term gains in text quality (pre–post) compared to the control group, whereas no differential effect emerged for EG2. Among high performers, text quality in EG2 remained more stable from pre to follow-up than in the control group.These findings provide insights into learner-specific benefits and limitations of digital writing tools. Given the increasing role of digital literacy, the study highlights the urgent need to align digital tools with differentiated writing instruction. Graham, S., & Harris, K. R. (2018).
