the effects of multiple intelligences (focus on musical, visual, and linguistic) and direct instruction on learning grammar: a case on iranian efl students at elementary level
1.0 overview it seems that grammar plays a crucial role in the area of second and foreign language learning and widely has been acknowledged in grammar research. in other words, teaching grammar is an issue which has attracted much attention to itself, and a lot of teachers argue about the existence of grammar in language teaching and learning. this issue will remind us a famous sentence f...
Note on " Electromagnetism and Gravitation "
We obtain Hamilton equations for the gravitational field and demonstrate the conservation of total energy. We derive the Poisson bracket equation for a general dynamical variable.
متن کاملthe effects of keyword and context methods on pronunciation and receptive/ productive vocabulary of low-intermediate iranian efl learners: short-term and long-term memory in focus
از گذشته تا کنون، تحقیقات بسیاری صورت گرفته است که همگی به گونه ای بر مثمر ثمر بودن استفاده از استراتژی های یادگیری لغت در یک زبان بیگانه اذعان داشته اند. این تحقیق به بررسی تاثیر دو روش مختلف آموزش واژگان انگلیسی (کلیدی و بافتی) بر تلفظ و دانش لغوی فراگیران ایرانی زیر متوسط زبان انگلیسی و بر ماندگاری آن در حافظه می پردازد. به این منظور، تعداد شصت نفر از زبان آموزان ایرانی هشت تا چهارده ساله با...
15 صفحه اولOn Generalized Electromagnetism and Dirac Algebra*
Using a framework of Dirac algebra, the Clifford algebra appropriate for Minkowski space-time, the formulation of classical electromagnetism including both electric and magnetic charge is explored. Employing the two-potential approach of Cabibbo and Ferrari, a Lagrangian is obtained that is dyality invariant and from which it is possible to derive by Hamilton’s principle both the symmetrized Ma...
متن کاملReliability and performance of RAIDs - Magnetics, IEEE Transactions on
We define and analyze the ACATS declustering scheme for use with the classic Level 5 as well as MDS RAIDs. ACATS provides a paradigm for distributed sparing and checking as well. Using Markov models we calculate the reliability of classic Level 5 as well as MDS RAIDs both with and without ACATS. Our results demonstrate, for fixed hardware configurations, tradeoffs between performance and reliab...
