Furthermore, it also investigates the students’ responses toward the mediating practices through the Dynamic Assessment activities. Thirty-one students of the English Diploma program in a public university in (country) participated in the study. The study employed a mixed-method explanatory sequential design. The data were gathered through pretest, posttest, and observation of online records. Paired-sample t-test and independent sample t-test were utilized to find out the significance. The Reciprocity Framework was used to analyze the students’ responses to the mediating practices. The results show that mobile-mediated Dynamic Assessment effectively enhances students’ writing skills.
