اغلب تحقیقات انجام شده در حوزه ی " یادگیری مشارکتی " نشان ازتاثیرات مثبت آن بر موفقیت تحصیلی ، افزایش دانش و توانش زبانی، انگیزه ، تعاملات میان دانش آموزان(مهارتهای گروهی و پذیرش افراد با سطح درسی ضعیفتردر گروه)، و هم چنین علاقه به محیط آموزشی دارد .البته لازم به ذکر است که تحقیقاتی هم حاکی از عدم تاثیر این نوع یادگیری وجود دارد. بر اساس این پیشینه ، پژوهش حاضر به بررسی تاثیر "مدل یادگیری با هم...
15 صفحه اولIntergalactic Matter And Cocoons of Radio Galaxies
The cocoons surrounding powerful radio sources can be extensive if the jet that feeds the cocoon is light and supersonic. They have been shown to remain overpressured with respect to the ambient medium for most of the life time of the sources. The observed lobes of the radio sources form parts of these extensive cocoons. We show that observations of the lobes of giant radio sources allow one to...
متن کاملStructure and physical properties of silkworm cocoons.
Silkworm cocoons have evolved a wide range of different structures and combinations of physical and chemical properties in order to cope with different threats and environmental conditions. We present our observations and measurements on 25 diverse types of cocoons in a first attempt to correlate physical properties with the structure and morphology of the cocoons. These two architectural param...
متن کاملExtragalactic MeV γ-ray emission from cocoons of young radio galaxies
Strong γ-ray emission from cocoons of young radio galaxies is newly predicted. Considering the process of adiabatic injection of the shock dissipation energy and mass of the relativistic jet in active nuclei (AGNs) into the cocoon, while assuming thermalizing electron plasma interactions, we find that the thermal electron temperature of the cocoon is typically predicted in ∼MeV, which is determ...
متن کاملThe impact behaviour of silk cocoons.
Silk cocoons, constructed by silkmoths (Lepidoptera), are protective structural composites. Some cocoons appear to have evolved towards structural and material optimisation in order to sustain impact strikes from predators and hinder parasite ingress. This study investigates the protective properties of silk cocoons with different morphologies by evaluating their impact resistance and damage to...
