a comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
15 صفحه اولCombination effect of grazing intensity and livestock type (sheep, cattle and integrated grazing) on physical and chemical properties of soil (Case study: woody rangelands of Savadkouh city, Mazandaran)
Intense grazing of rangeland is one of the most important factors affecting rangeland degradation, which causes soil compaction, increased runoff, weakening and degradation of vegetation, and changes in rangeland species composition, and ultimately affects forage and livestock production. The present study was conducted to investigate the different intensities of cattle and sheep grazing and in...
متن کاملEffects of cattle grazing timing and intensity on soil seed banks and regeneration strategies in a Mediterranean grassland
The relationship between the soil seed bank at the onset of the growing season and the structure of the ensuing vegetation under grazing was investigated in an eastern Mediterranean grassland. Species responses to two contrasting cattle grazing regimes were studied through plant trait analyses. Traits included plant size, phenology, seed size and germination fraction. Changes in species composi...
متن کاملDoes Multitasking Impair Studying? Depends on Timing
It is often said that contemporary students frequently study while ‘multitasking’. However, this rather diffuse term encompasses situations that vary as to the whether the learner controls the pace at which educational materials are provided. On the basis of prior cognitive research, we hypothesize that this may well be a critical determinant of interference. Three studies required students to ...
متن کاملeffect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars
این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
