Cloze-Elide Test as an Alternative Test Method: Linking Personality Types to Test Method Performance
More innovative test methods may measure language learners’ test performance more accurately, contributing to much fairer decisions. This study examined Iranian language learners’ performance on cloze-elide test as an innovative, integrative test method. It specifically focused on investigating whether personality types correlated with their performance and whether personality types could predi...
abstract cooperative learning refers to small groups of learners working together as a team to solve a problem, complete a task, or accomplish a common goal. in a cooperative environment one’s success is directly related to the success of other members because the focus on the individual shifts towards the group. to test the effectiveness of the method, using jigsaw technique, a study was cond...
this thesis attempts to measure learning styles, self efficacy and intrinsic motivation as predictors of iranian ielts reading comprehension. in order to address this issue, a quantitative study was conducted on some randomly selected intact students at ferdowsi university. these two groups were assigned as they were undergraduate (ba=91) and graduate (ma =74) students; they were all aged betwe...
When the Vlasov equation is investigated numerically using the method of test particles, the two-body interactions that inevitably arise in the simulation (but are not present in the Vlasov equation itself) drive the collection of test particles toward a state of classical thermal equilibrium. We estimate the relaxation time associated with this thermalization. The Vlasov equation plays a centr...
One of the most important advantages of particle simulation as compared to fluid simulation is the capacity for working with and tracing particles. In particle simulations, the test particle method is usually used to get some idea of the behavior of plasma or other substances. In this method, first, a small number of particles are injected into the frame of static electromagnetic fields. Then, ...
Magnetic particle testing (MT) is the most sensitive method to detect surface cracks in ferromagnetic materials [2]. This method can be executed by mobile equipment or stationary systems [3]. Magnetic particles are used for the visualisation of the surface cracks. The magnetic particles are an iron oxide powder coated with visible or fluorescent paint. They are also called test agent or magneti...
the angle of repose of soil particles is an important factor for determining critical shear stress for initiation of soil particles motion during the erosion process. there are different methods for measuring the angle of particle repose and the result of each method is somewhat different from those of the others. sliding and fixed-base piling methods are the two most common methods in the lite...
An efficient multigrid-FEM method for the detailed simulation of solid-liquid two phase flows with large number of moving particles is presented. An explicit fictitious boundary method based on a FEM background grid which covers the whole computational domain and can be chosen independently from the particles of arbitrary shape, size and number is used to deal with the interactions between the ...
The present report discusses our new simplified measuring method of masticatory efficiency by counting particles in the matter of making test materials and the standard equation for subjects with normal dentition. 1. Two kinds of hydrocolloid impression materials, reversible and irreversible, were used as the test materials. 2. For evaluating the shape of test materials, 12 subjects with normal...
the following question poped up: is there any relationship between iranian high school efl learners reading comprehension and listening comprehension? then the following null hypothesis (ho) was developed to the test the above, mentioned question. "there is no relationship between high school efl learners reading comprehension and listening comprehension. for nearly 16 weeks, the experimental g...
