In particular, visual literacy, which refers to the interpretation of elements other than written text, including images, symbols, shapes, and colors, has come into prominence through new learning approaches that emphasize the importance of using numerous stimuli. All texts convey a meaning and a message, which to comprehend requires textual analysis, the different theories and methods of which vary among various types of texts. As discussed in this article, the semiotic analysis theory provides tools for textual analysis concerning the dimensions of narrative discourse.Purpose: This study aimed to determine how a writing lecture activity based on semiotic analysis theory affects students' writing skills. To that end, cartoon caricatures were selected as visual texts for analysis.Method: This experimental research based on pre-and post-tests was conducted with a dependent group of 40 7 th -grade students in a school within Turkey's Ministry of Education. Data collection involved having each student develop two texts for caricature analysis: one prior to an experiment based on the traditional approach, and the other after an experiment based on the semiotic method. The differences between scores received for each text by all students were analyzed.
