the effects of cognitive strategies- note making and underlining- on iranian efl learners’ reading comprehension
هدف از انجام این مطالعه ، بررسی اثرات استفاده از استراتژی های شناختی یعنی "نت برداری" و "زیر خط کردن" بر روی عملکرد درک مطلب زبان آموزان ایرانی می باشد. به این منظور، 60 زبان آموز دختر سال چهارم دبیرستان از طریق آزمون پیشرفت زبان انگلیسی (نلسون)، از یک جامعه آماری بزرگتر انتخاب شدند. سپس به صورت تصادفی به سه گروه که هر گروه شامل ?0 دانش آموز همسان بود، تقسیم شدند: دو گروه آزمایش(گروه "نت برداری...
15 صفحه اولOn the Nature of the Solar Chromosphere
DOT high-resolution imagery suggests that only internetworkspanning Hα “mottles” constitute the quiet-sun chromosphere, whereas more upright network “straws” in “hedge rows” reflect transition-region conditions.
متن کاملModeling the Solar Chromosphere
Spectral diagnostic features formed in the solar chromosphere are few and difficult to interpret — they are neither formed in the optically thin regime nor in local thermodynamic equilibrium (LTE). To probe the state of the chromosphere, both from observations and theory, it is therefore necessary with modeling. I discuss both traditional semi-empirical modeling, numerical experiments illustrat...
متن کاملThe prolate solar chromosphere
We present a comparative analysis of the chromospheric solar limb prolateness, using strictly simultaneous Hα ground-based observations and HeII space-based observations. The typical prolateness is found to be ∆D/D = 5.5 × 10−3 in HeII and 1.2 × 10−3 in Hα. The first measurements in the 30.4 nm HeII line over a period of two years, as well as coronal data, are discussed to explore further the o...
متن کاملThe New Chromosphere
The natural state of the Solar chromosphere is very dynamic. Any photospheric disturbance will grow and naturally form shocks over the twenty scale-heights in density between the photosphere and the corona. Observations in the resonance lines from singly ionized calcium and recently in the ultraviolet region of the spectrum observed with the Solar and Heliospheric Observatory satellite also sho...
