امروزه تصحیح همکلاسی در کلاسهای نگارش یکی از اجزاء لاینفک کلاسهای دانش آموز محور است. تاثیرات مفید تصحیح همکلاسی بر زبان آموزان، معلمان را متقاعد کرده است که علیرغم صرف زمان، انرژی و توان بسیار، از این شیوه ی آموزشی در کلاسهای آموزش نگارش بهره بگیرند. تحقیق حاضر بر آن است تا با مقایسه دو گروه از یادگیرندگان زبان انگلیسی، تاثیر تصحیح همکلاسی را بر توانایی نوشتاری آنها نشان دهد. 122 خانم زبان آمو...
15 صفحه اولClinical studies of dental erosion and erosive wear.
We define erosion as a partial demineralisation of enamel or dentine by intrinsic or extrinsic acids and erosive tooth wear as the accelerated loss of dental hard tissue through the combined effect of erosion and mechanical wear (abrasion and attrition) on the tooth surface. Most experts believe that during the last decade there has been a significant increase in the prevalence and severity of ...
متن کاملWear of dental amalgam.
The wear of cental amalgam was studied by single- and double-pass sliding and by a silicon carbide abrasion test. A dispersed amalgam showed significantly better resistance to two-body abrasion than the spherical amalgams tested. The wear amalgam was determined by resistance to penetration and by a ductile mode of surface failure over the load range studied. Differences in the wear of amalgam a...
متن کاملWear of Aged Dental Composites
Surface morphology and wear characteristics of five dental composites subjected to accelerated aging were investigated. Aging conditions caused degradation of the surface as evidenced by the formation of microcracks and the exposure and loss of filler particles. Wear parameters such as track width, transition load and mode of surface failure caused by single-pass sliding were influenced by agin...
