Abstract
When different disciplines that physics lesson is related are examined, it is seen that mathematics becomes prominent as one of the most used fields. Physics textbooks are the most significant resources to clarify this relationship. Therefore, in this study, it is aimed to analyze the involvement of mathematical knowledge in physics textbooks used during 2011-2012 and 2016-2017 academic year in Turkey and to evaluate them according to mathematics subject distribution. In line with this aim, 9th, 10th, 11th, and 12th-grade textbooks used in physics lessons during 2011-2012 and 2016-2017 academic years are examined through document analysis method. According to the research results, it is found that mathematical knowledge is mostly located in Force and Movement chapters in both physics textbooks belonging to two different years. The involvement of mathematical knowledge in the chapters can result from the fact that Force and Movement chapters are the most suitable chapters for daily practices of mathematics. Besides, it occurs that the most used mathematical knowledge is the category of numbers and operations. This is because of the fact that basic level knowledge is used more because all mathematical knowledge is based on numbers and four operations. In this respect, that mathematical knowledge involved in physics textbooks is very excessive stands as the most significant evidence for that there is a strong connection between physics and mathematics.
Highlights
The textbook is an indispensable tool and of generalized use in the classes of sciences [1]
As a result of examining 9th, 10th, 11th and 12th grades physics textbooks used in 2011-2012 and 2016-2017 academic years, mathematical knowledge in the books will be presented and comparisons will be made regarding the distribution of this information according to grade levels
The distribution of the mathematical knowledge given in the categories according to the class levels as a result of the observation made according to the categories is given in Table 1 below
Summary
The textbook is an indispensable tool and of generalized use in the classes of sciences [1]. Solving ability regarding complex and interdependent problems belonging to different disciplines and individuals face in their daily lives should be taught in educational institutions [6] Both learning knowledge and skills regarding a specific discipline and creating synthesis by combining these with different subjects and fields can be obtained [7]. As seen, when the extent of mathematical knowledge in the physics textbooks is examined, it is seen that most are included in the chapter of Force and Motion at both two different academic years. The same chapter, in the new textbooks for 10th-grades, contains 147 pieces of mathematical knowledge, which is the second most after the Force and Motion chapter. The matter and its properties chapter used to place in the books for all four grades, it is only in books for 9th and
