the impact of computer-assisted language learning on achievement motivation of high school students

چکیده انگیزه دلیل اصلی رفتارهای ما است. به نظر می رسد انگیزه جزء جدایی ناپذیر فرایند یادگیری باشد. ارزش ذاتی موفقیت تمایل به پیشرفت را در یادگیرنده ایجاد میکند. به عبارت ساده این تمایل انگیزه پیشرفت نامیده میشود. انگیزه پیشرفت را میتوان در احساس یادگیرنده هنگام چالش با درس های مدرسه، لذت انجام فعالیت درسی، یا حس کشف پاسخ مشاهده کرد.حتی ممکن است انگیزه پیشرفت را در تلاش یادگیرنده برای جلب تایید...

High-performance Tubular Evaporator Utilizing High Aspect Ratio Manifold Microchannels

Title of Document: HIGH-PERFORMANCE TUBULAR EVAPORATOR UTILIZING HIGH ASPECT RATIO MANIFOLD MICROCHANNELS Vibhash Chandra Jha, Doctor of Philosophy, 2012 Directed By: Michael Ohadi, Professor Department of Mechanical Engineering Heat recovery using absorption chillers has not been economical for small scale applications due to high capital requirements and heavy weight/volume as deterring facto...

EXPERIMENTAL INVESTIGATION OF OFFSHORE WAVE BUOY PERFORMANCE

The important characteristic of sea waves is their high energy density, which is the highest among renewable energy sources. Having up to 2700 km. of shoreline, Iran has a great potential in construction of offshore wave buoys (hereafter called OWB). In this article a OWB model with the possibility of assembling different buoy configurations is introduced. The system is exposed to regular and i...

An Experimental Investigation into the Effects of High Viscosity and Foamy Oil Rheology on a Centrifugal Pump Performance

This paper presents the effect of high viscosity oil and two-phase foamy-oil flow on the performance of a single stage centrifugal pump. As a part of this, the applicability of a pipe viscometer to determine the foamy oil viscosity is investigated. Unlike previous studies, a sealed fluid tank is used in a closed flow loop to allow conditioning the two-phase mixture to create foamy-oil. Furtherm...
