摘要：Our research is focused on quantitative and mixed study of LES textbooks for learners of secondary high school. In quantitative study, we were particularly interested in how to balance between the textbooks chapters and their corresponding textual and cartographic summaries. In this respect, we initially tried to evaluate the correlation and agreement between the chapters and their abstracts; and then, we tried to specify the kinds of knowledge maps used in the summaries and comparing them to concept maps and mind maps methods. Our study has shown that there is no correlation for 50% of LES in high school textbooks, and a correlation ranging between 0.21 and 0.93 for those that demonstrated a positive correlation. In mixed study, we have also identified, through information unit (IU) evaluation, that there is a mismatch between the content of the summaries and their corresponding chapters. Agreement of content between textual summaries and related chapters is located by 54% and 68%. Agreement of content of cartographic summaries varies between 49% and 72% in 60% of the studied corpus. The study has also shown that 22% of the summaries are textual, 34% are cartographic and 45% are both textual and cartographic.
