This experimental study aimed to investigate the relationship between text structure (TS) in argumentations written by Hebrew-speaking primary school children and their reading comprehension (RC) performance. A total of 293 students from second to fifth grade wrote an argumentative text and completed two RC tasks. These tasks consisted of a passage followed by multiple-choice questions targeting different levels of reading comprehension: literal, inferential, evaluative, and gap-filling questions. The students’ scores on the RC tasks were calculated, and their arguments were classified into different levels of complexity based on various structural components. Significant associations were found between text structure and grade level, with the most complex texts produced by students in the highest grade. However, there were fluctuations in the elaboration of text components across different grade levels. Correlations between reading comprehension and text structure were found to be weak and dependent on grade level. Children who scored higher on inferential reading comprehension questions tended to produce texts that were better structured and provided lengthier support for the writer’s claims.

Composing a well-written text is a prolonged and challenging process. The present study explored the incipient stages in descriptive texts written (pen and paper) or dictated by 283 Hebrew-speaking Israeli children in second to fifth grades. This study aims to better understand the interplay between age, literacy-related abilities, and descriptive text quality by exploring developmental aspects across grade levels regarding text structural quality, length of text and literacy related abilities, and by analyzing the relation between text structural quality and literacy related abilities (cognitive, transcriptional, linguistic, and reading), beyond length of text and grade level. Regarding the developmental aspects, the results indicate that text structure quality becomes more sophisticated and complete with age, attaining high-quality descriptive text structure from third grade on in the production of autonomous texts with genre-driven elaborate features. Length of text and literacy related abilities also increase with age. Regarding the relation between text structural quality and literacy related abilities, we found in 2nd grade, for P&P text, a significant total effect of syntactic lexical ability on text structure rank, partially mediated by length of text, and a weaker but still significant direct effect of syntactic lexical ability on TS rank, when controlling for length of text. We also found in 5th grade, for DICT text, a significant total effect of reading high ability on TS rank, not mediated by length of text.
