a paradigm shift away from method-wise teaching to strategy-wise teaching: an investigation of reconstructive strategy versus communicative strategy
چکیده: هدف اصلی این مطالعه ی توصیفی تحقیقی در حقیقت تلاشی پساروش-گرا به منظور رسیدن به نتیجه ای منطقی در انتخاب مناسبترین راهکار آموزشی بر گرفته از چارچوب راهبردی مطرح شده توسط والدمر مارتن بوده که به بهترین شکل سازگار و مناسب با سامانه ی آموزشی ایران باشد. از این رو، دو راهکار آموزشی، راهکار ارتباطی و راهکار بازساختی، برای تحقیق و بررسی انتخاب شدند. صریحاً اینکه، در راستای هدف اصلی این پژوهش، ر...
15 صفحه اولProtective Effects of α-Tocopherol on ABR Threshold Shift in Rabbits Exposed to Noise and Carbon Monoxide
Noise induced hearing loss (NIHL) is one of the most important occupational disease worldwide. NIHL has been found potentiate by simultaneous carbon monoxide (CO) exposure. Free radicals have been implicated in cochlear damage resulted from the exposure to noise and due to the CO hypoxia. This study examined whether α-tocopherol administration, as a free radical scavenger, causes the attenuatio...

Prolonged Exposure to Industrial Noise: Cochlear Pathology does not Correlate with the Degree of Permanent Threshold Shift, but is Related ́ ́ to Duration of Exposure: Mariola SLIWINSKA-KOWALSKA, et al. Department of Physical Hazards, The Nofer Institute of Occupational Medicine—It has been shown that the damaging effects of noise on the mammalian inner ear strongly depend upon parameters of exp...
متن کاملhearing loss resulting from noise exposure in textile workers
measurement and analysis of noise level in various frequency bands was carried out in a textile factory. it was shown that the noise level in various working places, particularly in the weaving workshop, was quite excessive comparing to the standards and so, it may very likely result in producing hearing loss in the workers. to determine the hearing loss of the workers due to excessive noise, 1...
