The research aims at :Identifying if the levels of cognitive depth are involving in the content of text books of science and biology in the intermediate stage, To achieve the first object، the researcher prepared a list of levels of cognitive depth through presenting an open questionnaire to experts specialized in the methods of teaching in biology, and made a review of the studies and books that dealt with levels of cognitive depth، as a list of levels of cognitive depth was reached in its initial form، and in order to verify its validity, it was presented to group of judges specialized in the methods of teaching in biology in the College of Education and some of the supervisors and teachers، and thus the list was formed in its final form of four levels of cognitive depth (first level remembering and reproduction، second level application of concepts and skills، third level strategic thinking The fourth level: Extended Thinking) Forty items are emerged from these four levels which are distributed on these levels.

Then analyze the textbooks of science and biology for intermediate stage for study year 2021- 2022.

According the list that prepared depending on explicit and implicit themes A unit for recording and repetition and a unit for counting،.

Validity is verified through calculating analysis of agreement with external analysts and with the researcher himself.

On a sample of students consisting of (200) male and female students from the third intermediate grade who were randomly selected from middle schools in the center of Al-Diwaniyah city.Some statistical means were used to achieve the following findings: Availability of levels of cognitive depth in middle school textbooks in varying proportions, The levels of cognitive depth vary in the three textbooks when compared to the ratios of the criteria, Significant increase in the level of (remembering and reproduction) in the sciences textbooks of the second intermediate grade and the third intermediate grade book compared to the ratio of the criteria.

In light of the findings of the research، the researcher came up with several recommendations, including: 1-Taking into account the ratios of the levels of depth of knowledge in the biology book for the third intermediate grade in light of the spoken ratios established by the arbitrators and avoiding the discrepancy between the four levels، through the participation of experts in the field of educational and psychological sciences in the writing of textbooks.

2- Paying attention to the textbook، in terms of quantity and quality، to raise the level of students، which contributes to acquiring all kinds of thinking skills.

3-Conducting scientific seminars for teachers of biology to familiarize them with the levels of depth of knowledge and how to develop it among students.
