اگرکیفیت معلم کلاس برای بهبودیادگیری دانش آموزحیاتی است،پس کیفیت اساتیددانشجو-معلمان، یابه عبارتی معلمین معلمان نیزبرای پیشرفت آموزش بسیارمهم واساسی است.ناگفته پیداست که یک سیستم مناسب آموزش معلمان ،معلمین با کیفیتی را تربیت خواهدکرد.که این کار منجربه داشتن مدارس خوب، ودرنتیجه نیروی کارماهرتروشهروندبهتربرای جامعه خواهدشد. اساتیددانشجو-معلمان نقشی بسیارمهم را در سیستم اموزش معلمان درسراسرجهان ای...
the estimation of velocity distribution plays a major role in the hydrodynamics of vegetated streams or rivers of extensive natural floodplains. the velocity profile in vegetated channels can be divided into three zones: uniform zone which is close to bed with uniform velocity distribution, logarithmic zone which involves the main channel with no vegetive cover and the transition zone that is a...
in this paper an energy dissipation rate control (edrc) method is introduced, which could provide stable walking or running gaits for legged robots. this method is realized by developing a semi-analytical pattern generation approach for a robot during each single support phase (ssp). as yet, several control methods based on passive dynamic walking have been proposed by researchers to provide an...
in this article wee seek to suggest an analytical model for explaining the israeli foreign policy. to do this, we must, on the one hand, survey briefly the main theories of foreign polcy and, on the other, to review the literature about the israeli foreign policy. the major question this paper would ask is: what are the main factors shaping the israeli foreign policy and which one might be said...
The life of many people in the world is under the danger because of the accidents and unpredicted diseases, which require relief. Since, most of such cases occur in unpredictable condition, for an appropriate planning, the uncertain conditions should be investigated. Consequently, this paper investigates the integrated and multi-step process of locating, assigning and routing the air and la...
an aircraft wing needs to display different mechanical behavior in different directions. 1- stiffness in the spanwise (transverse to the corrugation) direction which enables the aerodynamic and inertial loads to be carried. 2- compliance in the chordwise (corrugation) direction which would allow shape changes and increases in surface area; whereas a corrugated sheet due to their special geometr...
Penetration into non-homogeneous concrete- steel target is of prime importance to applied scients and civilian analyzers. Due to complexly of the problem, most of the work done in this experimental in nature. In this Study, an analytical solution of long rod projectile penetrating depth into concrete targets with applying the analytical model of Alekseeveskiis-Tate, and for concrete/steel targe...
abstract the present study was conducted to investigate the effect of using model essays on the development of writing proficiency of iranian pre-intermediate efl learners. to fulfill the purpose of the study, 55 pre- intermediate learners of parsa language institute were chosen by means of administering proficiency test. based on the results of the pretest, two matched groups, one as the expe...
