Cotent analysis of mathematics books of 12th grade in branch mathematics and physics, published in 2018

The purpose of study is to analyze the content of the mathematical books of the 12th students in Mathematical and Physical branch published in 1397, which includes Geometry (3), Discrete Mathematics and Calculus (2). In this research, the problems in exercises and work in the classes and activities in these books, according to the five categories of modeling and application areas, namely "without background", "unreasonable circuit background", "background field" Independent of the field "," Standard application "and" Modeling "were reviewed and coded. The results of the study showed that uncontrolled issues constitute a high percentage of the studied issues. So that 99% of the issues in the book of geometry (3), 75.18% of the discrete mathematical questions and 92.22% of the book of calculus (2) were unconditional, and after them, the questions " Independent of the field "and" standard application ". In Geometric books (3) and discrete mathematics, there were no questions "unreasonable circuit background", but 68.6% of the questions examined in the of Calculus (2) were in this category. Also, none of the surveyed questions was in three books on "modeling", which is indicative of the lack of consideration of the modeling approach and applications in these three books.
