The aim of this research is to evaluate the sub-structure of thought in the written texts of students of 5th, 6th, 7th and 8th classes who are studying in the middle school stage. For this purpose, the basic thoughts on the level of words, sentences and paragraphs in written texts, the supporting thoughts, the direction of support and the arrangement of the thoughts in the text have been studied. The research is an imaginary quality study that aims to reveal the current facts. The universe of research is formed by high school students. The study’s sample consists of 439 students who studied in 4 high schools by random method determined from the Hatay or Antakya and Defne central districts. As a data collection tool, the study used the "Development Score Key for the Thought Substructure in Information Text", the "Evaluation Form for the Distribution of Thoughts according to Language Units" and the "Evaluation Form for the Organization of Thoughts in the Text". According to the findings obtained, the basic and supporting thoughts in the written texts of high school students do not show a balanced distribution; the basic thoughts, the direction of support and the use of supporting thoughts are missing; problems with the arrangement of the thoughts are experienced.
