a comparative study of the relationship between self-, peer-, and teacher-assessments in productive skills
تمایل به ارزیابی جایگزین و تعویض آن با آزمون سنتی مداد و کاغذ در سالهای اخیر افزایش یافته است. اکثر زبان آموزان در کلاس های زبان از نمره نهایی که استاد تعیین میکند ناراضی اند. این تحقیق جهت بررسی ارزیابی در کلاس های زبان انگلیسی به هدف رضایتمندی زبان آموزان از نمره هایشان انجام گرفته است که در آن نمرات ارائه شده توسط سه گروه ارزیاب (ارزیابی خود دانشجو، همسالان واستاد) در مهارت های تولید (تکل...
15 صفحه اولflexural strength of cold and heat cure acrylic resins reinforced with different materials
o bjectives: heat-polymerized acrylic resin has been the most commonly used denture base material for over 60 years. however, the mechanical strength of acrylic resin is not adequate for long-term clinical performance of dentures. consequently, fracture is a com- mon clinical occurrence, which often occurs in the midline of denture base.this study aimed to evaluate the efficacy of cold cure and...
متن کاملEffect of Storage Conditions and Disinfection with 2% Deconex® on Dimensional Stability of Two Self-Cure Acrylic Resins
Background and Aim: There is a gap of information on the effect of time, disinfectant, and storage conditions on the dimensional stability of direct post patterns made of self-cure acrylic resins. This study assessed the effect of Deconex® and wet or dry stor-age conditions on the dimensional stability of post patterns made of Duralay and GC acrylic resins. Materials and Methods: Sixty spe...
متن کاملComparison of Impact Strength and Fracture Morphology of Different Heat Cure Denture Acrylic Resins: An In vitro Study
BACKGROUND The fracture of acrylic resin denture is rather common occurrence and causes inconvenience to the patients. This study was carried out to evaluate and compare the impact strength and fracture morphology of four different heat cure acrylic materials. MATERIALS AND METHODS Acrylic resin specimens were prepared using preformed metal die of dimension 65 × 10 × 3 mm. The specimens were ...
متن کاملThe Evaluation of Water Sorption/Solubility on Various Acrylic Resins
OBJECTIVES The absorption of water by acrylic resins is a phenomenon of considerable importance since it is accompanied by dimensional changes, a further undesirable effect of absorbed water in acrylic resins to reduce the tensile strength of the material. Solubility is also an important property because it represents the mass of soluble materials from the polymers. METHODS Ten acrylic resin-...
