This study aimed to create medical terminology flashcards in the form of teaching and learning aids for use in the specialized language and medical terminology courses at Guilan University of Medical Sciences, Iran. To achieve the objective of the study, first, a needs analysis was conducted, which showed the scarcity of such educational materials and students’ needs for them. Next, the structure and the content of information of the flashcards were developed; then, the designed flashcards were examined and modified. Afterwards, professors who were experienced in teaching medical terminology and specialized language courses evaluated the flashcards using a questionnaire. Moreover, an interview was conducted with the professors on ways to improve the quality of the flashcards. The results showed that the professors were satisfied with the potential learning effects, the structure, and the content of information of the flashcards. They also suggested a few modifications to the flashcards and recommended that the flashcards should be used in the university courses. The study has implications for the development of educational materials in the form of teaching and learning aids.

Classroom discourse refers to the language and interaction used by the teacher and the students to communicate and shape learning in the educational context. The present study focused on Iranian EFL teachers’ classroom discourse by observing their dominancy, teacher talk, question types, and interactions in their classes. To do so, through a non-experimental, descriptive research design, 20 female experienced teachers with the age range of 30-40, teaching at an upper-intermediate level in different language institutes in Isfahan, Iran were selected based on the convenience sampling. Two classes of the teachers were observed, the sessions were recorded, and their classroom discourses were transcribed and later analyzed. Moreover, to increase the validity and reliability of the research, a semi-structured interview was conducted with volunteer participants; their reflections on their communication with the learners and discourse types were collected and analyzed using descriptive statistics in terms of frequency and percentages. The findings of the study showed that the teachers made use of specific discourse to ascertain their dominance and control in their classes. The findings also revealed that the teachers used more monologic discourse patterns in their classes rather than dialogic ones. Teacher talk far exceeded student talk, Initiation-Response-Feedback pattern dominated the classroom discourse; and display questions were used more frequently than referential ones. These findings could benefit teachers to be more conscious about type of CD and its effect on student-to-student and teacher-to-student interactions. It could also serve the purpose of critical classroom discourse analysis

The most common starting point for investors when buying a stock is to look at the trend of price changes. In recent years, different models have been used to predict stock prices by researchers, and since artificial intelligence techniques, including neural networks, genetic algorithms and fuzzy logic, have achieved successful re-sults in solving complex problems; in this regard, more exploitation Are. In this research, the prediction of stock prices of companies accepted in the Tehran Stock Exchange using artificial intelligence algorithm (non-sensory-parametric support vector regression algorithm in linear and nonlinear mode) has been investigated. The results of the research show that the PINSVR algorithm in nonlinear mode has been able to predict the stock price over the years, rather than linear mode.
