- چکیده:
- چکیده انگلیسی: A Split plot experiment based on randomized complete block design (RCBD) with three replications was conducted in 2012,Treatments were included the time of foliar application with 3 levels (tillering stage, heading stage and no spray (control)) as main factor and cultivars in 4 levels (Sardari, Rijav, Biseton and Rashid) as the second factor. Plant characteristics such as plant height, length of the peduncle, length of stamen, diameter of node, the number of node, and spike of length Fe and leaf area index were considered. Results showed that the time of Fe foliar application had a significant effect on studying traits. With respect to Duncan's Multiple Range test, mean comparison results revealed that the Fe foliar application at tillering stage and treatment control (no application) had the greatest and the least effect on traits respectively. Also there was significantly different among cultivars, as among cultivars the maximum and minimum mean of traits was obtained for Rijav and Rashid respectively. The interaction of foliar application × cultivar for plant height and leaf area index was also significant. Highest the wheat height and LAI were observed at foliar application in tillering with Rijav cultivar and the lowest means to control with the Rashid it can be concluded that the most suitable application of Fe solution for improvement morphological and physiological properties of different dry land wheat cultivars (in the same climate condition) was tillering stage, since more impression of Fe was observed in early growth stages

- چکیده: این مطالعه با هدف بررسی نقش جنسیت و تجربه در تدریس در آگاهی معلمان زبان انگلیسی ایرانی از استاندارد های اخلاقی در تحقیق انجام شده است. 272 معلم ایرانی زبان انگلیسی بر اساس نمونه گیری آسان انتخاب شدند و از طریق پرسشنامه دانش معلمان زبان انگلیسی ایرانی در مورد استانداردهای اخلاقی در تحقیق ارزیابی شدند. پس از جمع آوری پرسشنامه ها ، داده ها توسط نرم افزار اماری "اس پی اس اس" مورد تجزیه و تحلیل قرار گرفت. از آزمون "تی" مستقل برای ارزیابی اینکه آیا دانش معلمان از اخلاق در تحقیقات به طور قابل توجهی بین دو جنس متفاوت است استفاده شد. علاوه بر این ، همبستگی پیرسون برای یافتن رابطه بین تجربه در تدریس و عامل فوق الذکر انجام شد. یافته ها رابطه مثبت و معناداری بین هر پنج زیرساخت اخلاق و تجربه را نشان داد. علاوه بر این ، یافته ها نشان داد که در میزان دانش معلمان از اخلاق پژوهشی و زیرساخت های آن بین معلمان زن و مرد تفاوت معناداری وجود دارد. میانگین نمره معلمان زن در تمام زیرساخت ها از معلمان مرد بیشتر است. این مطالعه ممکن است تنها پژوهشی باشد که در ایران دانش معلمان را در مورد عواملی که بر آگاهی آنها از اصول اخلاقی در تحقیق تأثیر می گذارد را مورد بررسی قرار داده است.
- چکیده انگلیسی: This study is aimed at examining the role of gender, and years of teaching experience in Iranian EFL teachers’ awareness of the code of ethics in research. 272 Iranian EFL teachers were chosen based on convenience sampling and were assessed through the Iranian EFL teachers’ awareness of the code of ethics in research scale inventory. After gathering the questionnaires, data was analysed by SPSS. An independent-samples t-test was performed to examine whether the teachers' awareness of the code of ethics in research differs significantly between genders. In addition, Pearson correlation was performed to find the connection between years of teaching experience and the aforementioned factor. The findings showed substantial positive relationships between all five sub-constructs of the code of ethics and experience. Besides, the findings revealed that there were considerable differences in the degree of knowledge among EFL teachers of research codes of ethics and its sub-constructs between male and female teachers. The mean score of the female teachers in all sub-constructs was higher than the male teachers. This study may be the only piece of research that has investigated the EFL teachers’ knowledge regarding factors affecting their awareness of the code of ethics in research in Iran.
