Second Language Writing Development of Turkish Undergraduate Students
Reyhan Ağçam, Mahmut Özkan

Abstract
The present study aims to explore the writing development of a group of elementary-level students attending English Preparatory Programme at a state university in Turkey. It entails a detailed quantitative analysis of data including texts produced by 21 students on an online platform over a ten-week period to describe and outline linguistic changes that could take place between the commence and end of the semester. The findings have revealed that lexical density of the texts has increased significantly, that not a significant difference was found across the texts in terms of readability, and that the number of different words used by the students has consistently increased from the first week onwards despite slight fluctuations. It has been revealed that phonological and syntactic errors were the most frequented error types whereas lexical and morphological errors randomly appeared in the texts throughout the semester.
