the effect of task complexity on efl learners’ written task performance in terms of accuracy and complexity
هدف اصلی این تحقیق بررسی تاثیر افزایش میزان پیچیدگی تکالیف مکالمه محور بر دقت و صحت و پیچیدگی عملکرد نوشتاری زبان آموزان می باشد. بدین منظور، 50 نفر از دانش آموزان دختر در رده ی سنی 15 الی 18 سال درسطح pre-intermediate از طریق petو vhs تست به عنوان شرکت کنندگان در تحقیق انتخاب شدند و به دو گروه آزمایشی و کنترل بصورت اتفاقی تقسیم شدند. اعضای گروه آزمایشی دو تکلیف ساده و پیچیده را طی 2 جلسه انجام...
an investigation of accuracy and complexity across different proficiency levels in written narrative task
abstract this quasi-experimental study was aimed at examining the impact of storyline complexity on the grammatical accuracy and complexity of advanced and intermediate efl learners. a total of 65 advanced and intermediate efl learners were selected from iran language institute (ili). an intact group including 35 intermediate participants and another intact group with 30 advanced participants ...
Revision #2 Raman spectroscopy and the inversion degree of natural Cr-bearing spinels
Natural Cr-spinels already characterized by X-ray single crystal diffraction and electron microprobe have been analyzed by Raman spectroscopy. The results we report show that there is a strong correlation between the Cr/(Cr+Al) ratio (Cr#) and the A1g mode for the studied spinels. A strong correlation of this mode with Mg/(Mg+Fe) (Mg#) can be seen only for spinels with Mg# higher than 0.60. Oth...
متن کاملChemical Compositions and Tectonic Significance of Chrome-Rich Spinels in the Tianba Flysch, Southern Tibet
Turbiditic sandstones from the mid–Late Cretaceous Tianba Flysch sequence are well exposed near Tianba in the north Nieru Valley, southern Tibet, and contain significant amounts of chrome-rich spinels. Microprobe results show that the spinels have a well-developed Fe-Ti trend and have Cr/( ) 0.4–0.65, Mg/( ) 0.3–0.9, and TiO2 2 Cr Al Mg Fe 11%. The occurrence of melt inclusions, and well above ...
متن کاملInversion of long-lived trace gas emissions using combined Eulerian and Lagrangian chemical transport models
We present a method for estimating emissions of long-lived trace gases from a sparse global network of high-frequency observatories, using both a global Eulerian chemical transport model and Lagrangian particle dispersion model. Emissions are derived in a single step after determining sensitivities of the observations to initial conditions, the high-resolution emissions field close to observati...
