The purpose of this study was to investigate the scientific and professional competencies of first grade high school math teachers in Tehran.The statistical population of the study was the first grade mathematics teachers of high schools in Tehran in the academic year1398-99, whichwereselected as a sample using cluster sampling of 537 people. The research tool was a researchermade questionnaire with98 items in the form of9componentsof educational,scientific,behavioral,social,intellectual,managerial,ethical, professional and technological competencies of teachers. Its validity was confirmed by experts and Cronbach's alpha coefficient was calculated to be86%The results of t-test showed that educational,scientific,behavioral, managerial and moral competencies are above the average and are significant at the confidence level of0.99 But professional and social competencies are not significant at the level of0.95 confidence but the status of technological and intellectual competencies is significant at the level of0.95confidence,and teachers in these competencies are in the status.They are not desirable.The results of independent t-test show that the status of male teachers is higher than female teachers in terms of social and intellectual competencies but the status of female teachers in educational qualifications is better than male teachers. The results show that there is no significant difference between male and female teachers in other variables

Thermal imaging provides new opportunities to study biological concepts and processes. Examples include the use of infrared (IR) cameras in educational activities to discover the transfer and evolution of energy in human physiology, the readjustment of animal body temperature, and the metabolism of plants. The user-friendly and intuitive nature of IR technology, due to such energy transfer, is suitable for studying rapid temperature changes at biological levels; Thus, IR cameras are potentially useful educational tools for approaching the concept of the intersection of energy and matter. This camera represents a new generation of research technology that shows great potential in biology education. This review article provides an overview of trying to introduce IR cameras to schools and empowering students to make credible scientific discoveries. The information collected is from articles on Google, Google Scholar, Scopus, and Science Direct. The articles reviewed in this study are from 1985 to 2021. The aim is to show how the advanced technologies developed by industry can be transformed into effective learning technologies to solve educational problems.

Trigonometry is one of the basic and widely used concepts in mathematics, other sciences, and life. Students may be face misconceptions in learning trigonometry that prevent them from fully learning the lesson. Identifying these misconceptions and avoiding them is essential. Teachers have an important and critical role in addressing and preventing them and can be efficient to help students to improve their learning. In this article, we explore some of the misconceptions that arise for high school students when learning trigonometry and related topics. The article also offers solutions to this misconception, including the use of appropriate teaching methods, the use of tools such as calculators and mathematical software such as GeoGebra. We explain that how teachers can use these methods. In addition, the use of concept maps is recommended as another way of resolving misconceptions. We explain that concept maps can be used both in teaching and in assessing students.

The purpose of this study is to investigate the misunderstandings of twelfth grade students in the subject of acid-base. The statistical population of this study is equal to the quantity of the twelfth grade students of two schools in Rasht who are studying in the fields of experimental sciences and mathematics-physics in the academic year 1399-1400. The statistical sample consists of 47 students who were randomly selected. As a data collection tool, a four-choice three-row acid-base diagnostic test was designed and used. To analyze the data, the appropriate method was used with a three-tier test and students' perceptions were examined in three categories: scientific understanding, lack of understanding and misunderstanding. The results revealed some misunderstandings of acid-base concepts in students. Students are misunderstood, from more to less frequency, in the concepts of electrolyte, concentration of hydronium ion in dilute acidic solution, neutralization reaction, differentiation of decomposition concentration and acid equilibrium concentration, detection of acids and bases, ionization and separation concepts, ionization degree, ionization of several acids Protonates and misunderstandings of the concepts of strength and acid concentration. Identified misunderstandings can be used to improve teaching-learning methods and provide appropriate educational content.

The purpose of this study was to investigate the effect of digital literacy and mathematical progress on mathematical anxiety in junior high school students in Dehdasht. The research was conducted by descriptive correlation method. The statistical population included all female high school students in Dehdasht in 470 in 1399. The sample size was based on Krejcie and Morgan (1970) table and 210 people were selected as a statistical sample by possible multi-stage sampling method. To collect the data, the Digital Literacy Questionnaire based on the Digital Literacy Skills Framework of the Open University and the Student Mathematical Anxiety Questionnaire, the Chiu and Henry Mathematical Anxiety Scale for Children (MESC) and 1990 (1990) were used. Pearson correlation coefficient and linear regression were used to analyze the data. The results showed that the Pearson correlation coefficient (R) between the independent variable and the dependent variable (mathematical anxiety) was -0.751, which showed that there is a significant significant and inverse correlation. Adjusted determination coefficient equal to / 563. Shows that 56% of all changes in the mathematical anxiety variable depend on the digital literacy variable.

The purpose of this study was to analyze the fifth grade science textbook of elementary school and explain it based on the model of participatory creativity. In this study, descriptive-analytical method was used to access the data. The statistical population of Fifth grade science curriculum for elementary school in the academic year 1399-1400 was that the sample size was selected equal to the size of the population. The research tool included a content analysis checklist based on the method of William Rumi, whose content validity was obtained by 87% of curriculum planning experts. To determine its reliability, the method of William Scott (2019) was used and the agreement coefficient was 85%. the analyzed content was first examined based on the six indicators of scientific creativity and then the five stages of the participatory creativity model. Findings showed that scientific creativity has been used in three sections of writing, images and questions of science textbook, and the indicators of scientific problem solving and hypothesis building have been emphasized more. the science curriculum has considered the pattern of participatory creativity in a combined way, but based on the three parts of the content, it has been more reflected in the written part.
