The purpose of this investigation is to compare and study the effect of learning by physic concepts method and traditional method on student’ s Mathematic Academic motivation. The method of study was semi-experimental and the sample contains two groups of 31 students from the college grade in Tabriz 4th Education Office were selected and studied after random Replacement in two groups (learning by physic concepts method and traditional method). In the process of implementation, In Mathematics Education classroom, first group was subjected to learning by physic concepts method, And the second group was trained in the same traditional method. Covariance analysis method results show significant difference between two learning methods in effect two classes students’ Academic motivation in all components (Self-Esteem, Internal motivation and insert). The Students that trained in the physic concepts method showed higher academic motivation.

The purpose of this research is to analyze the national identity in the 10th Grade mathematics and statistics textbook. The method of research is quantitative and qualitative content analysis. The dimensions of national identity in this research are the symbol, value, cultural heritage, celebrities and characters, events and happenings. The statistical population is the 10th Grade mathematics and statistics textbook. The results of the quantitative analysis show that 55 references to the concept of national identity are mentioned. Among the dimensions of national identity, the dimension of cultural heritage with 38. 18% of the highest frequency and events and happenings with 1. 81% have the lowest frequency. The results of the qualitative analysis show the attention to books and to places and buildings in the cultural heritage, and the low use of hadiths, verses. Also, in the dimension of national values, attention to social values and in the dimension of celebrities and characters, the lack of attention to contemporary celebrities.

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.

Education and research in the field of biology requires other basic sciences, especially chemistry. Understanding the chemical structure of biological molecules and their reactions is essential to the treatment of disease. Cancer is an abnormal growth of cells in the body that was previously healthy. To prevent the growth of cancer cells, the drugs used should prevent their growth by interacting with the DNA of these cells. The first drug that was introduced as an anticancer drug is diamminedichloroplatinum(II) or cisplatin complex. This complex loses its chlorine atoms in the body and is converted to diamindihydroxoplatinium(II). Subsequently, due to its flat square structure, in the vicinity of the DNA of the cancer cells, the quenched hydroxide anions of platinum(II) cations with N7 atoms are displaced by adjacent guanine bands and, after DNA binding to these cells, prevents their growth. Platinum(IV) complexes are more stable than platinum(II) complexes, and in the biological environment they become platinum(II) in the presence of ascorbic acid and glutamic acid, and quaternized by cellular DNA, like cisplatin. Also, the functions of gold(III) complexes for eliminate cancer cells is like cisplatin.

Using multiple intelligence categories in school books in order to learn school lessons, has an increasing impact on learner's educational achievement. This research’ s goal is to analyze the content of the animal section in biology book of the eleventh grade based on Multiple Intelligence Theory of Gardner. The method used in this research is content analysis and Statistical population is all pages of animal section of 11’ th grade’ s book and we didn’ t use sampling in this research in Inferential statistics in order to have a significant test, we used chi-2 Statistical test and results of this study showed that there is a significant difference between Intelligence components in this section of the book, which is beneficial for verbal-linguistically intelligence. Also, the usage of intelligence components in Content presentation templates (text, images, and activities) are not same. We can conclude from results of this research that the components of intelligence are not equally used in the different chapters of the book.

Studying the understanding of teacher students about scientific concepts is more essential than the study of students' perceptions, as a perceived misunderstanding among the teachers affects the student's understanding. The aim of this study was to determine the chemistry teacher students' understanding about some concepts of electrochemistry and comparing the result obtained with the outcomes for the students. The sample of the study was 47 chemistry teacher students of Farhangian University. In order to identify the misconceptions, a questionnaire containing seven questions about some of the most important concepts related to electrochemistry have been used. The test was conducted under normal class conditions without previous warning. In order to evaluate their understanding and to extract their misconceptions, student’ s responses were analyzed statistically and descriptively after data collection. The results obtained indicated that, the level of understanding of teacher students' is very high in comparison with students, but some of them have the same misconceptions as high school students have. Through interviews with some of these teacher students, some causes of misconceptions were identified.
